bb44e0bbce block: Handle multiwrite errors only when all requests have completed
Don't try to be clever by freeing all temporary data and calling all callbacks
when the return value (an error) is certain. Doing so has at least two
important problems:

* The temporary data that is freed (qiov, possibly zero buffer) is still used
  by the requests that have not yet completed.
* Calling the callbacks for all requests in the multiwrite means for the caller
  that it may free buffers etc. which are still in use.

Just remember the error value and do the cleanup when all requests have
completed.

This is what needs to be used for image format metadata to maintain integrity

6fd82592ce block/vdi: Fix image opening and creation for odd disk sizes
The fix is based on a patch from Kevin Wolf. Here his comment:

"The number of blocks needs to be rounded up to cover all of the virtual hard
disk. Without this fix, we can't even open our own images if their size is not
a multiple of the block size."

While Kevin's patch addressed vdi_create, my modification also fixes
vdi_open which now accepts images with odd disk sizes.

v3:
Don't allow reading of disk images with too large disk sizes.
Neither VBoxManage nor old versions of qemu-img read such images.
This change requires rounding of odd disk sizes before we do the checks.

39187b5192 block/vpc: Fix conversion from size to disk geometry
The VHD algorithm calculates a disk geometry
which is usually smaller than the requested size.

QEMU tried to round up but failed for certain sizes:

qemu-img create -f vpc disk.vpc 9437184
would create an image with 9435136 bytes
(which is too small for qemu-img convert).

Instead of hacking the geometry algorithm, the patch
increases the number of sectors until we get enough
sectors.

a513171f80 qcow2: Fix corruption after error in update_refcount

all changed entries to disk. If a refcount block allocation fails, however,
there was no change yet and therefore first_index = last_index = -1. Don't

ff9e177617 qcow2: Fix corruption after refblock allocation
Refblock allocation code needs to take into consideration that update_refcount
will load a different refcount block into the cache, so it must initialize the
cache for a new refcount block only afterwards. Not doing this means that not
only the refcount in the wrong block is updated, but also that the caller will
work on the wrong block.

07442ab4a1 Fix multiboot compilation
Commit dd4239d657 broke multiboot. It replaced the
instruction "rep insb (%dx), %es:(%edi)" by the binary output of
"addr32 rep insb (%dx), %es:(%di)".

Linuxboot calls the respective helper function in a code16 section. So the
original instruction was automatically translated to its "addr32" equivalent.
For multiboot, we're running in code32 so gcc didn't add the "addr32" which
breaks the instruction.

This patch splits that helper function in one which uses addr32 and one which
does not, so everyone's happy.

The good news is that nobody probably cared so far. The bundled multiboot.bin
binary was built before the change and is thus correct.

Please also put this patch into -stable.

7dd007c2ed target-ppc: fix RFI by clearing some bits of MSR
Since commit 2ada0ed, "Return From Interrupt" is broken for PPC processors
because some interrupt specifics bits of SRR1 are copied to MSR.

SRR1 is a save of MSR during interrupt.
During RFI, MSR must be restored from SRR1.
But some bits of SRR1 are interrupt-specific and are not used for MSR saving.

This is the specification (ISA 2.06) at chapter 6.4.3 (Interrupt Processing):
"2. Bits 33:36 and 42:47 of SRR1 or HSRR1 are loaded with information specific
    to the interrupt type.
 3. Bits 0:32, 37:41, and 48:63 of SRR1 or HSRR1 are loaded with a copy of the
    corresponding bits of the MSR."

Below is a representation of MSR bits which are not saved:
0:15 16:31 32  33:36    37:41      42:47     48:63
——— | ——— | — X X X X — — — — — X X X X X X | ————
0000 0000 |    7   |   8   |   3   |   F    | 0000

History:
In the initial Qemu implementation (e1833e1), the mask 0x783F0000 was used for
saving MSR in SRR1. But all the bits 32:47 were cleared during RFI restoring.
This was wrong. The commit 2ada0ed explains that this breaks Altivec.
Indeed, bit 38 (for Altivec support) must be saved and restored.
The change of 2ada0ed was to restore all the bits of SRR1 to MSR.
But it's also wrong.

Explanation:
As an example, let's see what's happening after a TLB miss.
According to the e300 manual (E300CORERM table 5-6), the TLB miss interrupts
set the bits 44-47 for KEY, I/D, WAY and S/L. These bits are specifics to the
interrupt and must not be copied into MSR at the end of the interrupt.
With the current implementation, a TLB miss overwrite bits POW, TGPR and ILE.

Fix:
It shouldn't be needed to filter-out bits on MSR saving when interrupt occurs.
Specific bits overwrite MSR ones in SRR1.
But at the end of interrupt (RFI), specifics bits must be cleared before
restoring MSR from SRR1. The mask 0x783F0000 apply here.

Discussion:
The bits of the mask 0x783F0000 are cleared after an interrupt.
I cannot find a specification which talks about this
but I assume it is the truth since Linux can run this way.
Maybe it's not perfect but it's better (works for e300).

72d3457e8d arm_timer: reload timer when enabled
Reload the timer when TimerControl is written, if the timer is to be
enabled.  Otherwise, if an earlier write to TimerLoad was done while
periodic mode was not set, s->delta may incorrectly still have the value
of the maximum limit instead of the value written to TimerLoad.

This problem is evident on versatileap on current linux-next, which
enables TIMER_CTRL_32BIT before writing to TimerLoad and then enabling
periodic mode and starting the timer.  This causes the first periodic
tick to be scheduled to occur after 0xffffffff periods, leading to a
perceived hang while the kernel waits for the first timer tick.

1fb9798b69 block: fix sector comparism in multiwrite_req_compare
The difference between the start sectors of two requests can be larger
than the size of the "int" type, which can lead to a not correctly
sorted multiwrite array and thus spurious I/O errors and filesystem
corruption due to incorrect request merges.

So instead of doing the cute sector arithmetics trick spell out the
exact comparisms.

Spotted by Kevin Wolf based on a testcase from Michael Tokarev.

As a result, we both saved a wrong value

This leads to device and bus irq counts getting

8cef921d18 qemu-img: use the heap instead of the huge stack array for win32
The default stack size of PE is 1MB on win32 and IO_BUF_SIZE in
img_convert() & img_rebase() is 2MB, so qemu-img will crash when doing
"convert" & "rebase" on win32.
Although we can improve the stack size of PE to resolve it, I think we
should avoid using the huge stack variables.

d04d7cf158 Workaround for broken OSS_GETVERSION on FreeBSD, part two
Turns out on those versions of FreeBSD (>= 7.x) that know OSS_GETVERSION
the ioctl doesn't actually work yet (except in the Linuxolator), so if

Register s0 had been used for TCG_AREG1 in earlier releases,

69ff4e9dbd net: remove broken net_set_boot_mask() boot device validation
There are many problems with net_set_boot_mask():

1) It is broken when using the device model instead of "-net nic". Example:
   $ qemu-system-x86_64 -device rtl8139,vlan=0,id=net0,mac=52:54:00:82:41:fd,bus=pci.0,addr=0x4 -net user,vlan=0,name=hostnet0 -vnc 0.0.0.0:0 -boot n
   Cannot boot from non-existent NIC
   $
2) The mask was previously used to set which boot ROMs were supposed to be
   loaded, but this was changed long time ago. Now all ROM images are loaded,
   and SeaBIOS takes care of jumping to the right boot entry point depending on
   the boot settings.
3) Interpretation and validation of the boot parameter letters is done on
   the machine type code. Examples: PC accepts only a,b,c,d,n as valid boot
   device letters. mac99 accepts only a,b,c,d,e,f.

As a side-effect of this change, qemu-kvm won't abort anymore if using "-boot n"
on a machine with no network devices. Checking if the requested boot device is
valid is now a task for the BIOS or the machine-type code.

fafc2e4b33 qcow2: Rewrite alloc_refcount_block/grow_refcount_table
The current implementation of alloc_refcount_block and grow_refcount_table has
fundamental problems regarding error handling. There are some places where an
I/O error means that the image is going to be corrupted. I have found that the
only way to fix this is to completely rewrite the thing.

In detail, the problem is that the refcount blocks itself are allocated using
alloc_refcount_noref (to avoid endless recursion when updating the refcount of
the new refcount block, which migh access just the same refcount block but its
allocation is not yet completed...). Only at the end of the refcount allocation
the refcount of the refcount block is increased. If an error happens in
between, the refcount block is in use, but has a refcount of zero and will
likely be overwritten later.

The new approach is explained in comments in the code. The trick is basically
to let new refcount blocks describe their own refcount, so their refcount will
be automatically changed when they are hooked up in the refcount table.

rest.

5c6892078a tcg/arm: correctly save/restore registers in prologue/epilogue
Since commit 6113d6d316 QEMU crashes
on ARM hosts. This is not a bug of this commit, but a latent bug
revealed by this commit.

The TCG code is called through a procedure call using the prologue
and epilogue code. This code does not save and restore enough registers.
The "Procedure Call Standard for the ARM Architecture" says:

  A subroutine must preserve the contents of the registers r4-r8, r10,
  r11 and SP (and r9 in PCS variants that designate r9 as v6).

The current code only saves and restores r9 to r11, and misses r4 to
r8. The patch fixes that by saving r4 to r12. Theoretically there is
no need to save and restore r12, but an even number of registers have
to be saved as per EABI.

18a21890ff workaround for cmd646 bmdma register access while no dma is active
This is a workaround only, and is a partial revert
of a few changes to BMDMAState which removed pci_dev
field on the way.

- cmd646 pci_from_bm() expects bm->unit value to
correspond with bm data being passed to callback
as opaque pointer. This breaks when write to dma
control register of second channel happens when no
dma operation is in progress, so bm->unit is zero
for second channel, and pci_from_bm() returns garbage
pointer. Crash happens shortly after that while
dereferencing that pointer.

v0->v1: cleaned up dead code from pci_from_bm.

57f9f4c9f5 don't dereference NULL after failed strdup
Most of these are obvious NULL-deref bug fixes, for example,
the ones in these files:

  block/curl.c
  net.c
  slirp/misc.c

and the first one in block/vvfat.c.
The others in block/vvfat.c may not lead to an immediate segfault, but I
traced the two schedule_rename(..., strdup(path)) uses, and a failed
strdup would appear to trigger this assertion in handle_renames_and_mkdirs:

	    assert(commit->path);

The conversion to use qemu_strdup in envlist_to_environ is not technically
needed, but does avoid a theoretical leak in the caller when strdup fails
for one value, but later succeeds in allocating another buffer(plausible,
if one string length is much larger than the others).  The caller does
not know the length of the returned list, and as such can only free
pointers until it hits the first NULL.  If there are non-NULL pointers
beyond the first, their buffers would be leaked.  This one is admittedly
far-fetched.

The two in linux-user/main.c are worth fixing to ensure that an
OOM error is diagnosed up front, rather than letting it provoke some
harder-to-diagnose secondary error, in case of exec failure, or worse, in
case the exec succeeds but with an invalid list of command line options.
However, considering how unlikely it is to encounter a failed strdup early
in main, this isn't a big deal.  Note that adding the required uses of
qemu_strdup here and in envlist.c induce link failures because qemu_strdup
is not currently in any library they're linked with.  So for now, I've
omitted those changes, as well as the fixes in target-i386/helper.c
and target-sparc/helper.c.

If you'd like to see the above discussion (or anything else)
in the commit log, just let me know and I'll be happy to adjust.

Subject: [PATCH] don't dereference NULL after failed strdup

Handle failing strdup by replacing each use with qemu_strdup,
so as not to dereference NULL or trigger a failing assertion.
* block/curl.c (curl_open): s/\bstrdup\b/qemu_strdup/
* block/vvfat.c (init_directories): Likewise.
(get_cluster_count_for_direntry, check_directory_consistency): Likewise.
* net.c (parse_host_src_port): Likewise.
* slirp/misc.c (fork_exec): Likewise.

beb8eab90c segfault due to buffer overrun in usb-serial
This fixes a segfault due to buffer overrun in the usb-serial device.
The memcpy was incrementing the start location by recv_used yet, the
computation of first_size (how much to write at the end of the buffer
before wrapping to the front) was not accounting for it. This causes the
next element after the receive buffer (recv_ptr) to get overwritten with

d3bf9367f2 QMP: Fix asynchronous events delivery
Commit f039a563f2 introduces
a regression as monitor_protocol_event() will return in
the first user Monitor it finds in the QLIST_FOREACH()
loop.

The right thing to do is to only delivery an asynchronous
event if the 'mon' is a QMP Monitor.

The aforementioned commit was an early version, if it was
applied to stable (it should) this one has to be applied
there too.

41ae9ece21 QMP: Emit asynchronous events on all QMP monitors
When using a control/QMP monitor in tandem with a regular monitor, asynchronous
messages can get lost depending on the order of the QEMU program arguments.
QEMU events issued by monitor_protocol_event() always go to cur_mon.  If the
user monitor was specified on the command line first (or it has ,default), the
message will be directed to the user monitor (not the QMP monitor).
Additionally, only one QMP session is currently able to receive async messages.

To avoid this confusion, scan through the list of monitors and emit the message
on each QMP monitor.

3999bf3244 Qemu's internal TFTP server breaks lock-step-iness of TFTP
According to RFC 1350 and RFC 2347, TFTP server should answer RRQ by
either OACK or DATA packet. Qemu's internal TFTP server answers RRQ with
additional options by sending both OACK and DATA packet, thus breaking
the "lock-step" feature of the protocol, and also confuses client.

  Proposed solution would be to, in case of OACK packet, wait for ACK
from client and just then start sending data. Attached patch implements
this.

66dbb62824 Handle TFTP ERROR from client
If a PXE client only wants to find out the size of a file, it will
open the file and then abort the transfer by sending a TFTP ERROR packet.

The ERROR packet should cause qemu to terminate the session. If not,
the sessions will soon run out and cause timeouts in the client.

Also, if a TFTP session already exists with same IP/UDP port, it
should be terminated when a new RRQ is received, instead of creating a
duplicate (which will never be used).

A patch for gPXE to send the ERROR packet is also being submitted to
gPXE. Together they resolve slowness/hanging when booting pxegrub from
qemu's internal TFTP server. The patch from Milan Plzik to return
after sending OACK is also required for a complete fix.

72bb3c7571 Support PCI based option rom loading
Currently, we preload option roms into the option rom space in memory.  This
prevents DDIM from functioning correctly which severely limits the number
of roms we can support.

This patch introduces a pci_add_option_rom() which registers the
PCI_ROM_ADDRESS bar which points to our option rom.  It also converts over
the cirrus vga adapter, the rtl8139, virtio, and the e1000 to use this
new mechanism.

The result is that PXE boot functions even with three unique types of cards.

4b5db3749c Fix VMware VGA depth computation
VMware VGA requires that the depth presented to the guest is the same as the
DisplaySurface that it renders to.  This is because it performs a very simple
memcpy() to blit from one surface to another.

We currently hardcode a 24-bit depth.  The surface allocator for SDL may, and
usually will, allocate a surface with a different depth causing screen
corruption.

This changes the code to allocate the DisplaySurface before initializing the
device which allows the depth of the DisplaySurface to be used instead of
hardcoding something.

3c547d7bb7 Make sure to enable dirty tracking of VBE vram mapping
Apparently, VBE maps the VGA vram to a fixed physical location.  KVM requires
that all mappings of the VGA vram have dirty tracking enabled on them.  Any
access to the VGA vram through the VBE mapping currently fails to result in
dirty page tracking updates causing a black screen.

This is the true root cause of VMware VGA not working correctly under KVM and
likely also an issue with some of the std-vga black screen issues too.

Cirrus does not enable VBE so it would not be a problem when using Cirrus.

5fd5f6999d monitor: Catch printing to non-existent monitor
The monitor_vprintf() function now touches the 'mon' pointer
before calling monitor_puts(), this causes block migration
to segfault as its functions call monitor_printf() with a
NULL 'mon'.

To fix the problem this commit moves the 'mon' NULL check
from monitor_puts() to monitor_vprintf().

This can potentially hide bugs, but for some reason this has
been the behavior for a long time.

9153014fa0 S390: Don't tell guest we're updating config space
Currently we always set the "config space changed" bit to 1 when triggering
any virtio interrupt. While that worked in 2.6.27, newer kernels interpret
that value as "only the config space changed and nothing else happened".

Since we usually trigger interrupts to tell the guest that something did
happen, we just not tell it the config space changed for now until we
implement the correct callback for that.

While that works, it's not exactly the fastest thing to do, since now the

97d949d9da osdep: Fix runtime failure on older Linux kernels
If QEMU finds newer kernel header files on compilation time, it will use
advertised features like pipe2 or SOCK_CLOEXEC by just doing a compile test.
If later the executables are executed on an older kernel (<2.6.27,
like Xen Dom0 2.6.18), then QEMU will fail on opening sockets and creating
pipes and returns the rather unspecific "qemu_init_main_loop failed".
This patch fixes this by checking the return values of these calls
for EINVAL and ENOSYS and falling back to the older versions automatically.

869ca150e7 target-mips: fix user-mode emulation startup
Running programs with the MIPS user-mode emulator fails during dynamic
loading, as floating-point instructions are not enabled in in
env->hflags.  Move the code for doing so from fpu_init to cpu_reset so
the MIPS_HFLAG_{FPU,F64} setting doesn't get clobbered by cpu_reset
setting env->hflags to MIPS_HFLAG_UM.

The same end can be achieved by swapping the ordering of fpu_init and
cpu_reset in cpu_mips_init, but it seemed better to consolidate the
CONFIG_USER_ONLY code into a single location.

d707483ce3 vnc: fix capslock tracking logic.
The capslock tracking logic added by commit
6b1325029d doesn't work correctly for vnc
clients without EXT_KEY_EVENT support.  The reason is that qemu converts
keysyms for letters to lowercase for the keysym2scancode lookup.  It
then also passes the lowercase value down to do_key_event(), but the
capslock tracking code needs it with the correct case to work properly.

This patch adds a new variable for the lowercase keysym so we'll keep
the unmodified value for do_key_event().

The keysym2scancode is not needed with EXT_KEY_EVENT capable clients
like any app based on the gtk-vnc widget, so I missed that case in
testing ...

6e792a557e scsi: fix drive hotplug.
This patch fills the DriveInfo->unit after hotplugging a scsi disk.
It makes a difference when auto-assigning a scsi id, where unit was
left filled with '-1' instead of the actual scsi id.

With this patch applied the the drive naming logic in drive_init() works
as good as it did in previous releases.  Which means it works fine with
a single scsi bus.

ea2138cf90 pci: don't hw_error() when no slot is available.
Current PCI code will simply hw_error() and thus abort in case no free
PCI slot is available or the requested PCI slot is already in use by
another device.  For the hotplug case this behavior is not acceptable.
This patch makes qemu pass up the error properly, so the calling code
can decide whenever it wants to exit with an error (on startup) or
whenever it wants to continue (hotplug).

992f3cb78e pci: don't abort() when trying to hotplug with acpi off.
The PCI bus on x86 requires ACPI for hotplug support, thus disbling ACPI
also disables hotplug for the PCI bus.  This patch makes qemu check
whenever the PCI bus in question can handle hotplug before trying to add
devices.  This is needed because qdev will abort() on any attempt to
hotplug devices into a non-hotpluggable bus.

828b2ff676 Set default console to virtio on S390x
All "normal" system emulation targets in qemu I'm aware of display
output on either VGA or serial output.

Our S390x virtio machine doesn't have such kind of legacy hardware. So
instead we need to default to a virtio console.

Add flags to QEMUMachine to indicate which kind of default devices make
sense for the machine in question.  Use it for S390x: enable virtcon,
disable serial, parallel and vga.

This patch adds a variable default_vga which says whenever a default

f49d2561cb qdev: add command line option to set global defaults for properties.
This patch adds infrastructure and command line option for setting
global defaults for device properties, i.e. you can for example use

  -global virtio-blk-pci.vectors=0

to turn off msi by default for all virtio block devices.  The config
file syntax is:

[global]
  driver = "virtio-blk-pci"
  property = "vectors"
  value = "0"

This can also be used to set properties for devices which are not
created via -device but implicitly via machine init, i.e.

  -global isa-fdc,driveA=<name>

This patch uses the mechanism which configures properties for the
compatibility machine types (pc-0.10 & friends).  The command line
takes precedence over the machine type values.

On hosts without high-res timers it is impossible to inject rtc interrupt
faster then 1kHz. Windows sometimes configures RTC to generate 1kHz
interrupts, so we can't inject missed interrupts when running on such
hosts. Always injecting an interrupt on REG_C read is also not an option
since Windows wait for REG_C to become zero with interrupt disabled
during boot. This patch uses mixed approach: accelerate timer + inject
up to 1000 interrupts on REG_C read.

b3dfdb5a3b monitor: Introduce 'block_passwd' command
When using encrypted disk images, QEMU will prompt the user
for passwords when started.

This makes sense for the user protocol, but doesn't for QMP.

The solution is to have Monitor command which allows the user
or a Client to set passwords in advance, so that we avoid
the prompt completely.

This is what block_passwd does, for example:

(QEMU) block_passwd ide0-hd0 foobar

This rearranges code in preparation for interrupt state
implementation.
Changes:
	- split up bus walk away from interrupt handling
          into a subroutine
	- change irq_state from an array to bitmask
	- verify that irq_state values are 0 or 1 on load

There are no functional changes.

066263f377 cpuid: Fix multicore setup on Intel
The multicore CPUID code detects whether the guest is an Intel or an
AMD CPU, because the Linux kernel is picky about the CmpLegacy bit.
KVM by default passes through the host's vendor, which was not
catched by the code. So fork out the vendor determining bits into a
separate function to be used from both places and always get the real
vendor.
This fixes KVM's multicore setup on Intel CPUs.

20c1a35211 kvm: x86: Fix initial kvm_has_msr_star
KVM_GET_MSR_INDEX_LIST returns -E2BIG when the provided space is too
small for all MSRs. But this is precisely the error we trigger with the
initial request in order to obtain that size. Do not fail in that case.

This caused a subtle corruption of the guest state as MSR_STAR was not
properly saved/restored. The corruption became visible with latest kvm
optimizing the MSR updates.

# This mailmap fixes up author names/addresses.
#
# If you are adding to this file consider if a similar change needs to
# be made to contrib/gitdm/aliases. They are not however completely
# analogous. .mailmap is concerned with fixing up damaged author
# fields where as the gitdm equivalent is more concerned with making
# sure multiple email addresses get mapped onto the same author.
#
# From man git-shortlog the forms are:
#
# Proper Name <commit@email.xx>
# <proper@email.xx> <commit@email.xx>
# Proper Name <proper@email.xx> <commit@email.xx>
# Proper Name <proper@email.xx> Commit Name <commit@email.xx>
#
# The first section translates weird addresses from the original git import
# into proper addresses so that they are counted properly by git shortlog.

Qemu Coding Style
=================
1. Whitespace
Of course, the most important aspect in any coding style is whitespace.
Crusty old coders who have trouble spotting the glasses on their noses
can tell the difference between a tab and eight spaces from a distance
of approximately fifteen parsecs. Many a flamewar have been fought and
lost on this issue.
QEMU indents are four spaces. Tabs are never used, except in Makefiles
where they have been irreversibly coded into the syntax.
Spaces of course are superior to tabs because:
- You have just one way to specify whitespace, not two. Ambiguity breeds
mistakes.
- The confusion surrounding 'use tabs to indent, spaces to justify' is gone.
- Tab indents push your code to the right, making your screen seriously
unbalanced.
- Tabs will be rendered incorrectly on editors who are misconfigured not
to use tab stops of eight positions.
- Tabs are rendered badly in patches, causing off-by-one errors in almost
every line.
- It is the QEMU coding style.
Do not leave whitespace dangling off the ends of lines.
2. Line width
Lines are 80 characters; not longer.
Rationale:
- Some people like to tile their 24" screens with a 6x4 matrix of 80x24
xterms and use vi in all of them. The best way to punish them is to
let them keep doing it.
- Code and especially patches is much more readable if limited to a sane
line length. Eighty is traditional.
- It is the QEMU coding style.
3. Naming
Variables are lower_case_with_underscores; easy to type and read. Structured
type names are in CamelCase; harder to type but standing out. Scalar type
names are lower_case_with_underscores_ending_with_a_t, like the POSIX
uint64_t and family. Note that this last convention contradicts POSIX
and is therefore likely to be changed.
Typedefs are used to eliminate the redundant 'struct' keyword. It is the
QEMU coding style.
4. Block structure
Every indented statement is braced; even if the block contains just one
statement. The opening brace is on the line that contains the control
flow statement that introduces the new block; the closing brace is on the
same line as the else keyword, or on a line by itself if there is no else
keyword. Example:
if (a == 5) {
printf("a was 5.\n");
} else if (a == 6) {
printf("a was 6.\n");
} else {
printf("a was something else entirely.\n");
}
An exception is the opening brace for a function; for reasons of tradition
and clarity it comes on a line by itself:
void a_function(void)
{
do_something();
}
Rationale: a consistent (except for functions...) bracing style reduces
ambiguity and avoids needless churn when lines are added or removed.
Furthermore, it is the QEMU coding style.

Formatting and style
********************
Whitespace
==========
Of course, the most important aspect in any coding style is whitespace.
Crusty old coders who have trouble spotting the glasses on their noses
can tell the difference between a tab and eight spaces from a distance
of approximately fifteen parsecs. Many a flamewar has been fought and
lost on this issue.
QEMU indents are four spaces. Tabs are never used, except in Makefiles
where they have been irreversibly coded into the syntax.
Spaces of course are superior to tabs because:
* You have just one way to specify whitespace, not two. Ambiguity breeds
mistakes.
* The confusion surrounding 'use tabs to indent, spaces to justify' is gone.
* Tab indents push your code to the right, making your screen seriously
unbalanced.
* Tabs will be rendered incorrectly on editors who are misconfigured not
to use tab stops of eight positions.
* Tabs are rendered badly in patches, causing off-by-one errors in almost
every line.
* It is the QEMU coding style.
Do not leave whitespace dangling off the ends of lines.
Multiline Indent
----------------
There are several places where indent is necessary:
* if/else
* while/for
* function definition & call
When breaking up a long line to fit within line width, we need a proper indent
for the following lines.
In case of if/else, while/for, align the secondary lines just after the
opening parenthesis of the first.
For example:
.. code-block:: c
if (a == 1 &&
b == 2) {
while (a == 1 &&
b == 2) {
In case of function, there are several variants:
* 4 spaces indent from the beginning
* align the secondary lines just after the opening parenthesis of the first
For example:
.. code-block:: c
do_something(x, y,
z);
do_something(x, y,
z);
do_something(x, do_another(y,
z));
Line width
==========
Lines should be 80 characters; try not to make them longer.
Sometimes it is hard to do, especially when dealing with QEMU subsystems
that use long function or symbol names. Even in that case, do not make
lines much longer than 80 characters.
Rationale:
* Some people like to tile their 24" screens with a 6x4 matrix of 80x24
xterms and use vi in all of them. The best way to punish them is to
let them keep doing it.
* Code and especially patches is much more readable if limited to a sane
line length. Eighty is traditional.
* The four-space indentation makes the most common excuse ("But look
at all that white space on the left!") moot.
* It is the QEMU coding style.
Naming
======
Variables are lower_case_with_underscores; easy to type and read. Structured
type names are in CamelCase; harder to type but standing out. Enum type
names and function type names should also be in CamelCase. Scalar type
names are lower_case_with_underscores_ending_with_a_t, like the POSIX
uint64_t and family. Note that this last convention contradicts POSIX
and is therefore likely to be changed.
When wrapping standard library functions, use the prefix ``qemu_`` to alert
readers that they are seeing a wrapped version; otherwise avoid this prefix.
Block structure
===============
Every indented statement is braced; even if the block contains just one
statement. The opening brace is on the line that contains the control
flow statement that introduces the new block; the closing brace is on the
same line as the else keyword, or on a line by itself if there is no else
keyword. Example:
.. code-block:: c
if (a == 5) {
printf("a was 5.\n");
} else if (a == 6) {
printf("a was 6.\n");
} else {
printf("a was something else entirely.\n");
}
Note that 'else if' is considered a single statement; otherwise a long if/
else if/else if/.../else sequence would need an indent for every else
statement.
An exception is the opening brace for a function; for reasons of tradition
and clarity it comes on a line by itself:
.. code-block:: c
void a_function(void)
{
do_something();
}
Rationale: a consistent (except for functions...) bracing style reduces
ambiguity and avoids needless churn when lines are added or removed.
Furthermore, it is the QEMU coding style.
Declarations
============
Mixed declarations (interleaving statements and declarations within
blocks) are generally not allowed; declarations should be at the beginning
of blocks.
Every now and then, an exception is made for declarations inside a
#ifdef or #ifndef block: if the code looks nicer, such declarations can
be placed at the top of the block even if there are statements above.
On the other hand, however, it's often best to move that #ifdef/#ifndef
block to a separate function altogether.
Conditional statements
======================
When comparing a variable for (in)equality with a constant, list the
constant on the right, as in:
.. code-block:: c
if (a == 1) {
/* Reads like: "If a equals 1" */
do_something();
}
Rationale: Yoda conditions (as in 'if (1 == a)') are awkward to read.
Besides, good compilers already warn users when '==' is mis-typed as '=',
even when the constant is on the right.
Comment style
=============
We use traditional C-style /``*`` ``*``/ comments and avoid // comments.
Rationale: The // form is valid in C99, so this is purely a matter of
consistency of style. The checkpatch script will warn you about this.
Multiline comment blocks should have a row of stars on the left,
and the initial /``*`` and terminating ``*``/ both on their own lines:
.. code-block:: c
/*
* like
* this
*/
This is the same format required by the Linux kernel coding style.
(Some of the existing comments in the codebase use the GNU Coding
Standards form which does not have stars on the left, or other
variations; avoid these when writing new comments, but don't worry
about converting to the preferred form unless you're editing that
comment anyway.)
Rationale: Consistency, and ease of visually picking out a multiline
comment from the surrounding code.
Language usage
**************
Preprocessor
============
Variadic macros
---------------
For variadic macros, stick with this C99-like syntax:
.. code-block:: c
#define DPRINTF(fmt, ...) \
do { printf("IRQ: " fmt, ## __VA_ARGS__); } while (0)
Include directives
------------------
Order include directives as follows:
.. code-block:: c
#include "qemu/osdep.h" /* Always first... */
#include <...> /* then system headers... */
#include "..." /* and finally QEMU headers. */
The "qemu/osdep.h" header contains preprocessor macros that affect the behavior
of core system headers like <stdint.h>. It must be the first include so that
core system headers included by external libraries get the preprocessor macros
that QEMU depends on.
Do not include "qemu/osdep.h" from header files since the .c file will have
already included it.
C types
=======
It should be common sense to use the right type, but we have collected
a few useful guidelines here.
Scalars
-------
If you're using "int" or "long", odds are good that there's a better type.
If a variable is counting something, it should be declared with an
unsigned type.
If it's host memory-size related, size_t should be a good choice (use
ssize_t only if required). Guest RAM memory offsets must use ram_addr_t,
but only for RAM, it may not cover whole guest address space.
If it's file-size related, use off_t.
If it's file-offset related (i.e., signed), use off_t.
If it's just counting small numbers use "unsigned int";
(on all but oddball embedded systems, you can assume that that
type is at least four bytes wide).
In the event that you require a specific width, use a standard type
like int32_t, uint32_t, uint64_t, etc. The specific types are
mandatory for VMState fields.
Don't use Linux kernel internal types like u32, __u32 or __le32.
Use hwaddr for guest physical addresses except pcibus_t
for PCI addresses. In addition, ram_addr_t is a QEMU internal address
space that maps guest RAM physical addresses into an intermediate
address space that can map to host virtual address spaces. Generally
speaking, the size of guest memory can always fit into ram_addr_t but
it would not be correct to store an actual guest physical address in a
ram_addr_t.
For CPU virtual addresses there are several possible types.
vaddr is the best type to use to hold a CPU virtual address in
target-independent code. It is guaranteed to be large enough to hold a
virtual address for any target, and it does not change size from target
to target. It is always unsigned.
target_ulong is a type the size of a virtual address on the CPU; this means
it may be 32 or 64 bits depending on which target is being built. It should
therefore be used only in target-specific code, and in some
performance-critical built-per-target core code such as the TLB code.
There is also a signed version, target_long.
abi_ulong is for the ``*``-user targets, and represents a type the size of
'void ``*``' in that target's ABI. (This may not be the same as the size of a
full CPU virtual address in the case of target ABIs which use 32 bit pointers
on 64 bit CPUs, like sparc32plus.) Definitions of structures that must match
the target's ABI must use this type for anything that on the target is defined
to be an 'unsigned long' or a pointer type.
There is also a signed version, abi_long.
Of course, take all of the above with a grain of salt. If you're about
to use some system interface that requires a type like size_t, pid_t or
off_t, use matching types for any corresponding variables.
Also, if you try to use e.g., "unsigned int" as a type, and that
conflicts with the signedness of a related variable, sometimes
it's best just to use the *wrong* type, if "pulling the thread"
and fixing all related variables would be too invasive.
Finally, while using descriptive types is important, be careful not to
go overboard. If whatever you're doing causes warnings, or requires
casts, then reconsider or ask for help.
Pointers
--------
Ensure that all of your pointers are "const-correct".
Unless a pointer is used to modify the pointed-to storage,
give it the "const" attribute. That way, the reader knows
up-front that this is a read-only pointer. Perhaps more
importantly, if we're diligent about this, when you see a non-const
pointer, you're guaranteed that it is used to modify the storage
it points to, or it is aliased to another pointer that is.
Typedefs
--------
Typedefs are used to eliminate the redundant 'struct' keyword, since type
names have a different style than other identifiers ("CamelCase" versus
"snake_case"). Each named struct type should have a CamelCase name and a
corresponding typedef.
Since certain C compilers choke on duplicated typedefs, you should avoid
them and declare a typedef only in one header file. For common types,
you can use "include/qemu/typedefs.h" for example. However, as a matter
of convenience it is also perfectly fine to use forward struct
definitions instead of typedefs in headers and function prototypes; this
avoids problems with duplicated typedefs and reduces the need to include
headers from other headers.
Reserved namespaces in C and POSIX
----------------------------------
Underscore capital, double underscore, and underscore 't' suffixes should be
avoided.
Low level memory management
===========================
Use of the malloc/free/realloc/calloc/valloc/memalign/posix_memalign
APIs is not allowed in the QEMU codebase. Instead of these routines,
use the GLib memory allocation routines g_malloc/g_malloc0/g_new/
g_new0/g_realloc/g_free or QEMU's qemu_memalign/qemu_blockalign/qemu_vfree
APIs.
Please note that g_malloc will exit on allocation failure, so there
is no need to test for failure (as you would have to with malloc).
Calling g_malloc with a zero size is valid and will return NULL.
Prefer g_new(T, n) instead of g_malloc(sizeof(T) ``*`` n) for the following
reasons:
* It catches multiplication overflowing size_t;
* It returns T ``*`` instead of void ``*``, letting compiler catch more type errors.
Declarations like
.. code-block:: c
T *v = g_malloc(sizeof(*v))
are acceptable, though.
Memory allocated by qemu_memalign or qemu_blockalign must be freed with
qemu_vfree, since breaking this will cause problems on Win32.
String manipulation
===================
Do not use the strncpy function. As mentioned in the man page, it does *not*
guarantee a NULL-terminated buffer, which makes it extremely dangerous to use.
It also zeros trailing destination bytes out to the specified length. Instead,
use this similar function when possible, but note its different signature:
.. code-block:: c
void pstrcpy(char *dest, int dest_buf_size, const char *src)
Don't use strcat because it can't check for buffer overflows, but:
.. code-block:: c
char *pstrcat(char *buf, int buf_size, const char *s)
The same limitation exists with sprintf and vsprintf, so use snprintf and
vsnprintf.
QEMU provides other useful string functions:
.. code-block:: c
int strstart(const char *str, const char *val, const char **ptr)
int stristart(const char *str, const char *val, const char **ptr)
int qemu_strnlen(const char *s, int max_len)
There are also replacement character processing macros for isxyz and toxyz,
so instead of e.g. isalnum you should use qemu_isalnum.
Because of the memory management rules, you must use g_strdup/g_strndup
instead of plain strdup/strndup.
Printf-style functions
======================
Whenever you add a new printf-style function, i.e., one with a format
string argument and following "..." in its prototype, be sure to use
gcc's printf attribute directive in the prototype.
This makes it so gcc's -Wformat and -Wformat-security options can do
their jobs and cross-check format strings with the number and types
of arguments.
C standard, implementation defined and undefined behaviors
==========================================================
C code in QEMU should be written to the C99 language specification. A copy
of the final version of the C99 standard with corrigenda TC1, TC2, and TC3
included, formatted as a draft, can be downloaded from:
`<http://www.open-std.org/jtc1/sc22/WG14/www/docs/n1256.pdf>`_
The C language specification defines regions of undefined behavior and
implementation defined behavior (to give compiler authors enough leeway to
produce better code). In general, code in QEMU should follow the language
specification and avoid both undefined and implementation defined
constructs. ("It works fine on the gcc I tested it with" is not a valid
argument...) However there are a few areas where we allow ourselves to
assume certain behaviors because in practice all the platforms we care about
behave in the same way and writing strictly conformant code would be
painful. These are:
* you may assume that integers are 2s complement representation
* you may assume that right shift of a signed integer duplicates
the sign bit (ie it is an arithmetic shift, not a logical shift)
In addition, QEMU assumes that the compiler does not use the latitude
given in C99 and C11 to treat aspects of signed '<<' as undefined, as
documented in the GNU Compiler Collection manual starting at version 4.0.
Automatic memory deallocation
=============================
QEMU has a mandatory dependency either the GCC or CLang compiler. As
such it has the freedom to make use of a C language extension for
automatically running a cleanup function when a stack variable goes
out of scope. This can be used to simplify function cleanup paths,
often allowing many goto jumps to be eliminated, through automatic
free'ing of memory.
The GLib2 library provides a number of functions/macros for enabling
automatic cleanup:
`<https://developer.gnome.org/glib/stable/glib-Miscellaneous-Macros.html>`_
Most notably:
* g_autofree - will invoke g_free() on the variable going out of scope
* g_autoptr - for structs / objects, will invoke the cleanup func created
by a previous use of G_DEFINE_AUTOPTR_CLEANUP_FUNC. This is
supported for most GLib data types and GObjects
For example, instead of
.. code-block:: c
int somefunc(void) {
int ret = -1;
char *foo = g_strdup_printf("foo%", "wibble");
GList *bar = .....
if (eek) {
goto cleanup;
}
ret = 0;
cleanup:
g_free(foo);
g_list_free(bar);
return ret;
}
Using g_autofree/g_autoptr enables the code to be written as:
.. code-block:: c
int somefunc(void) {
g_autofree char *foo = g_strdup_printf("foo%", "wibble");
g_autoptr (GList) bar = .....
if (eek) {
return -1;
}
return 0;
}
While this generally results in simpler, less leak-prone code, there
are still some caveats to beware of
* Variables declared with g_auto* MUST always be initialized,
otherwise the cleanup function will use uninitialized stack memory
* If a variable declared with g_auto* holds a value which must
live beyond the life of the function, that value must be saved
and the original variable NULL'd out. This can be simpler using
g_steal_pointer
.. code-block:: c
char *somefunc(void) {
g_autofree char *foo = g_strdup_printf("foo%", "wibble");
g_autoptr (GList) bar = .....
if (eek) {
return NULL;
}
return g_steal_pointer(&foo);
}
QEMU Specific Idioms
********************
Error handling and reporting
============================
Reporting errors to the human user
----------------------------------
Do not use printf(), fprintf() or monitor_printf(). Instead, use
error_report() or error_vreport() from error-report.h. This ensures the
error is reported in the right place (current monitor or stderr), and in
a uniform format.
Use error_printf() & friends to print additional information.
error_report() prints the current location. In certain common cases
like command line parsing, the current location is tracked
automatically. To manipulate it manually, use the loc_``*``() from
error-report.h.
Propagating errors
------------------
An error can't always be reported to the user right where it's detected,
but often needs to be propagated up the call chain to a place that can
handle it. This can be done in various ways.
The most flexible one is Error objects. See error.h for usage
information.
Use the simplest suitable method to communicate success / failure to
callers. Stick to common methods: non-negative on success / -1 on
error, non-negative / -errno, non-null / null, or Error objects.
Example: when a function returns a non-null pointer on success, and it
can fail only in one way (as far as the caller is concerned), returning
null on failure is just fine, and certainly simpler and a lot easier on
the eyes than propagating an Error object through an Error ``*````*`` parameter.
Example: when a function's callers need to report details on failure
only the function really knows, use Error ``*````*``, and set suitable errors.
Do not report an error to the user when you're also returning an error
for somebody else to handle. Leave the reporting to the place that
consumes the error returned.
Handling errors
---------------
Calling exit() is fine when handling configuration errors during
startup. It's problematic during normal operation. In particular,
monitor commands should never exit().
Do not call exit() or abort() to handle an error that can be triggered
by the guest (e.g., some unimplemented corner case in guest code
translation or device emulation). Guests should not be able to
terminate QEMU.
Note that &error_fatal is just another way to exit(1), and &error_abort
is just another way to abort().
trace-events style
==================
0x prefix
---------
In trace-events files, use a '0x' prefix to specify hex numbers, as in:
.. code-block::
some_trace(unsigned x, uint64_t y) "x 0x%x y 0x" PRIx64
An exception is made for groups of numbers that are hexadecimal by
convention and separated by the symbols '.', '/', ':', or ' ' (such as
PCI bus id):
.. code-block::
another_trace(int cssid, int ssid, int dev_num) "bus id: %x.%x.%04x"
However, you can use '0x' for such groups if you want. Anyway, be sure that
it is obvious that numbers are in hex, ex.:
.. code-block::
data_dump(uint8_t c1, uint8_t c2, uint8_t c3) "bytes (in hex): %02x %02x %02x"
Rationale: hex numbers are hard to read in logs when there is no 0x prefix,
especially when (occasionally) the representation doesn't contain any letters
and especially in one line with other decimal numbers. Number groups are allowed
to not use '0x' because for some things notations like %x.%x.%x are used not
only in Qemu. Also dumping raw data bytes with '0x' is less readable.
'#' printf flag
---------------
Do not use printf flag '#', like '%#x'.
Rationale: there are two ways to add a '0x' prefix to printed number: '0x%...'
and '%#...'. For consistency the only one way should be used. Arguments for
'0x%' are:
* it is more popular
* '%#' omits the 0x for the value 0 which makes output inconsistent

QEMU Monitor Protocol
=====================
Introduction
-------------
The QEMU Monitor Protocol (QMP) allows applications to communicate with
QEMU's Monitor.
QMP is JSON[1] based and has the following features:
- Lightweight, text-based, easy to parse data format
- Asynchronous events support
- Stability
For more information, please, refer to the following files:
o qmp-spec.txt QEMU Monitor Protocol current specification
o qmp-events.txt List of available asynchronous events
There are also two simple Python scripts available:
o qmp-shell A shell
o vm-info Show some information about the Virtual Machine
[1] http://www.json.org
Usage
-----
To enable QMP, QEMU has to be started in "control mode". There are
two ways of doing this, the simplest one is using the the '-qmp'
command-line option.
For example:
$ qemu [...] -qmp tcp:localhost:4444,server
Will start QEMU in control mode, waiting for a client TCP connection
on localhost port 4444.
It is also possible to use the '-mon' command-line option to have
more complex combinations. Please, refer to the QEMU's manpage for
more information.
Simple Testing
--------------
To manually test QMP one can connect with telnet and issue commands:
$ telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
{"QMP": {"capabilities": []}}
{ "execute": "query-version" }
{"return": {"qemu": "0.11.50", "package": ""}}

QEMU Monitor Protocol Specification - Version 0.1
1. Introduction
===============
This document specifies the QEMU Monitor Protocol (QMP), a JSON-based protocol
which is available for applications to control QEMU at the machine-level.
To enable QMP support, QEMU has to be run in "control mode". This is done by
starting QEMU with the appropriate command-line options. Please, refer to the
QEMU manual page for more information.
2. Protocol Specification
=========================
This section details the protocol format. For the purpose of this document
"Client" is any application which is communicating with QEMU in control mode,
and "Server" is QEMU itself.
JSON data structures, when mentioned in this document, are always in the
following format:
json-DATA-STRUCTURE-NAME
Where DATA-STRUCTURE-NAME is any valid JSON data structure, as defined by
the JSON standard:
http://www.ietf.org/rfc/rfc4627.txt
For convenience, json-object members and json-array elements mentioned in
this document will be in a certain order. However, in real protocol usage
they can be in ANY order, thus no particular order should be assumed.
2.1 General Definitions
-----------------------
2.1.1 All interactions transmitted by the Server are json-objects, always
terminating with CRLF
2.1.2 All json-objects members are mandatory when not specified otherwise
2.2 Server Greeting
-------------------
Right when connected the Server will issue a greeting message, which signals
that the connection has been successfully established and that the Server is
waiting for commands.
The format is:
{ "QMP": { "capabilities": json-array } }
Where,
- The "capabilities" member specify the availability of features beyond the
baseline specification
2.3 Issuing Commands
--------------------
The format for command execution is:
{ "execute": json-string, "arguments": json-object, "id": json-value }
Where,
- The "execute" member identifies the command to be executed by the Server
- The "arguments" member is used to pass any arguments required for the
execution of the command, it is optional when no arguments are required
- The "id" member is a transaction identification associated with the
command execution, it is optional and will be part of the response if
provided
2.4 Commands Responses
----------------------
There are two possible responses which the Server will issue as the result
of a command execution: success or error.
2.4.1 success
-------------
The success response is issued when the command execution has finished
without errors.
The format is:
{ "return": json-object, "id": json-value }
Where,
- The "return" member contains the command returned data, which is defined
in a per-command basis or an empty json-object if the command does not
return data
- The "id" member contains the transaction identification associated
with the command execution (if issued by the Client)
2.4.2 error
-----------
The error response is issued when the command execution could not be
completed because of an error condition.
The format is:
{ "error": { "class": json-string, "data": json-object, "desc": json-string },
"id": json-value }
Where,
- The "class" member contains the error class name (eg. "ServiceUnavailable")
- The "data" member contains specific error data and is defined in a
per-command basis, it will be an empty json-object if the error has no data
- The "desc" member is a human-readable error message. Clients should
not attempt to parse this message.
- The "id" member contains the transaction identification associated with
the command execution (if issued by the Client)
NOTE: Some errors can occur before the Server is able to read the "id" member,
in these cases the "id" member will not be part of the error response, even
if provided by the client.
2.5 Asynchronous events
-----------------------
As a result of state changes, the Server may send messages unilaterally
to the Client at any time. They are called 'asynchronous events'.
The format is:
{ "event": json-string, "data": json-object,
"timestamp": { "seconds": json-number, "microseconds": json-number } }
Where,
- The "event" member contains the event's name
- The "data" member contains event specific data, which is defined in a
per-event basis, it is optional
- The "timestamp" member contains the exact time of when the event occurred
in the Server. It is a fixed json-object with time in seconds and
microseconds
For a listing of supported asynchronous events, please, refer to the
qmp-events.txt file.
3. QMP Examples
===============
This section provides some examples of real QMP usage, in all of them
'C' stands for 'Client' and 'S' stands for 'Server'.
3.1 Server greeting
-------------------
S: {"QMP": {"capabilities": []}}
3.2 Simple 'stop' execution
---------------------------
C: { "execute": "stop" }
S: {"return": {}}
3.3 KVM information
-------------------
C: { "execute": "query-kvm", "id": "example" }
S: {"return": {"enabled": true, "present": true}, "id": "example"}
3.4 Parsing error
------------------
C: { "execute": }
S: {"error": {"class": "JSONParsing", "desc": "Invalid JSON syntax", "data":
{}}}
3.5 Powerdown event
-------------------
S: {"timestamp": {"seconds": 1258551470, "microseconds": 802384}, "event":
"POWERDOWN"}
4. Compatibility Considerations
--------------------------------
In order to achieve maximum compatibility between versions, Clients must not
assume any particular:
- Size of json-objects or length of json-arrays
- Order of json-object members or json-array elements
- Amount of errors generated by a command, that is, new errors can be added
to any existing command in newer versions of the Server
Additionally, Clients should always:
- Check the capabilities json-array at connection time
- Check the availability of commands with 'query-commands' before issuing them
5. Recommendations to Client implementors
-----------------------------------------
5.1 The Server should be always started in pause mode, thus the Client is
able to perform any setup procedure without the risk of race conditions
and related problems

===========
QEMU README
===========
QEMU is a generic and open source machine & userspace emulator and
virtualizer.
QEMU is capable of emulating a complete machine in software without any
need for hardware virtualization support. By using dynamic translation,
it achieves very good performance. QEMU can also integrate with the Xen
and KVM hypervisors to provide emulated hardware while allowing the
hypervisor to manage the CPU. With hypervisor support, QEMU can achieve
near native performance for CPUs. When QEMU emulates CPUs directly it is
capable of running operating systems made for one machine (e.g. an ARMv7
board) on a different machine (e.g. an x86_64 PC board).
QEMU is also capable of providing userspace API virtualization for Linux
and BSD kernel interfaces. This allows binaries compiled against one
architecture ABI (e.g. the Linux PPC64 ABI) to be run on a host using a
different architecture ABI (e.g. the Linux x86_64 ABI). This does not
involve any hardware emulation, simply CPU and syscall emulation.
QEMU aims to fit into a variety of use cases. It can be invoked directly
by users wishing to have full control over its behaviour and settings.
It also aims to facilitate integration into higher level management
layers, by providing a stable command line interface and monitor API.
It is commonly invoked indirectly via the libvirt library when using
open source applications such as oVirt, OpenStack and virt-manager.
QEMU as a whole is released under the GNU General Public License,
version 2. For full licensing details, consult the LICENSE file.
Building
========
QEMU is multi-platform software intended to be buildable on all modern
Linux platforms, OS-X, Win32 (via the Mingw64 toolchain) and a variety
of other UNIX targets. The simple steps to build QEMU are:
.. code-block:: shell
mkdir build
cd build
../configure
make
Additional information can also be found online via the QEMU website:
* `<https://qemu.org/Hosts/Linux>`_
* `<https://qemu.org/Hosts/Mac>`_
* `<https://qemu.org/Hosts/W32>`_
Submitting patches
==================
The QEMU source code is maintained under the GIT version control system.
.. code-block:: shell
git clone https://git.qemu.org/git/qemu.git
When submitting patches, one common approach is to use 'git
format-patch' and/or 'git send-email' to format & send the mail to the
qemu-devel@nongnu.org mailing list. All patches submitted must contain
a 'Signed-off-by' line from the author. Patches should follow the
guidelines set out in the CODING_STYLE.rst file.
Additional information on submitting patches can be found online via
the QEMU website
* `<https://qemu.org/Contribute/SubmitAPatch>`_
* `<https://qemu.org/Contribute/TrivialPatches>`_
The QEMU website is also maintained under source control.
.. code-block:: shell
git clone https://git.qemu.org/git/qemu-web.git
* `<https://www.qemu.org/2017/02/04/the-new-qemu-website-is-up/>`_
A 'git-publish' utility was created to make above process less
cumbersome, and is highly recommended for making regular contributions,
or even just for sending consecutive patch series revisions. It also
requires a working 'git send-email' setup, and by default doesn't
automate everything, so you may want to go through the above steps
manually for once.
For installation instructions, please go to
* `<https://github.com/stefanha/git-publish>`_
The workflow with 'git-publish' is:
.. code-block:: shell
$ git checkout master -b my-feature
$ # work on new commits, add your 'Signed-off-by' lines to each
$ git publish
Your patch series will be sent and tagged as my-feature-v1 if you need to refer
back to it in the future.
Sending v2:
.. code-block:: shell
$ git checkout my-feature # same topic branch
$ # making changes to the commits (using 'git rebase', for example)
$ git publish
Your patch series will be sent with 'v2' tag in the subject and the git tip
will be tagged as my-feature-v2.
Bug reporting
=============
The QEMU project uses Launchpad as its primary upstream bug tracker. Bugs
found when running code built from QEMU git or upstream released sources
should be reported via:
* `<https://bugs.launchpad.net/qemu/>`_
If using QEMU via an operating system vendor pre-built binary package, it
is preferable to report bugs to the vendor's own bug tracker first. If
the bug is also known to affect latest upstream code, it can also be
reported via launchpad.
For additional information on bug reporting consult:
* `<https://qemu.org/Contribute/ReportABug>`_
Contact
=======
The QEMU community can be contacted in a number of ways, with the two
main methods being email and IRC
* `<mailto:qemu-devel@nongnu.org>`_
* `<https://lists.nongnu.org/mailman/listinfo/qemu-devel>`_
* #qemu on irc.oftc.net
Information on additional methods of contacting the community can be
found online via the QEMU website:
* `<https://qemu.org/Contribute/StartHere>`_

* An AsyncContext protects the callbacks of AIO requests and Bottom Halves
* against interfering with each other. A typical example is qcow2 that accepts
* asynchronous requests, but relies for manipulation of its metadata on
* synchronous bdrv_read/write that doesn't trigger any callbacks.
*
* However, these functions are often emulated using AIO which means that AIO
* callbacks must be run - but at the same time we must not run callbacks of
* other requests as they might start to modify metadata and corrupt the
* internal state of the caller of bdrv_read/write.
*
* To achieve the desired semantics we switch into a new AsyncContext.
* Callbacks must only be run if they belong to the current AsyncContext.
* Otherwise they need to be queued until their own context is active again.
* This is how you can make qemu_aio_wait() wait only for your own callbacks.
*
* The AsyncContexts form a stack. When you leave a AsyncContexts, you always
* return to the old ("parent") context.
