547435f550 migration: disable auto-converge during bulk block migration
auto-converge and block migration currently do not play well together.
During block migration the auto-converge logic detects that ram
migration makes no progress and thus throttles down the vm until
it nearly stalls completely. Avoid this by disabling the throttling
logic during the bulk phase of the block migration.

6a903482b1 Revert "ACPI: don't call acpi_pcihp_device_plug_cb on xen"
This reverts commit 153eba4726.

This patch prevents PCI passthrough hotplug on Xen. Even if the Xen tool
stack prepares its own ACPI tables, we still rely on QEMU for hotplug
ACPI notifications.

The original issue is fixed by the two previous patch:
  hw/acpi: Limit hotplug to root bus on legacy mode
  hw/acpi: Move acpi_set_pci_info to pcihp

8edf4c6adc hw/acpi: Move acpi_set_pci_info to pcihp
HW part of ACPI PCI hotplug in QEMU depends on ACPI_PCIHP_PROP_BSEL
being set on a PCI bus that supports ACPI hotplug. It should work
regardless of the source of ACPI tables (QEMU generator/legacy SeaBIOS/Xen).
So move ACPI_PCIHP_PROP_BSEL initialization into HW ACPI implementation
part from QEMU's ACPI table generator.

To do PCI passthrough with Xen, the property ACPI_PCIHP_PROP_BSEL needs
to be set, but this was done only when ACPI tables are built which is
not needed for a Xen guest. The need for the property starts with commit
"pc: pcihp: avoid adding ACPI_PCIHP_PROP_BSEL twice"
(f0c9d64a68).

Adding find_i440fx into stubs so that mips-softmmu target can be built.

The problem is that nbd_client_init() uses
nbd_client_attach_aio_context() -> aio_co_schedule(new_context,
client->read_reply_co).  Execution of read_reply_co is deferred to a BH
which doesn't run until later.

In the mean time blk_co_preadv() can be called and nbd_coroutine_end()
calls aio_wake() on read_reply_co.  At this point in time
read_reply_co's ctx isn't set because it has never been entered yet.

This patch simplifies the nbd_co_send_request() ->
nbd_co_receive_reply() -> nbd_coroutine_end() lifecycle to just
nbd_co_send_request() -> nbd_co_receive_reply().  The request is "ended"
if an error occurs at any point.  Callers no longer have to invoke
nbd_coroutine_end().

This cleanup also eliminates the segfault because we don't call
aio_co_schedule() to wake up s->read_reply_co if sending the request
failed.  It is only necessary to wake up s->read_reply_co if a reply was
received.

Note this only happens with UNIX domain sockets on Linux.  It doesn't
seem possible to reproduce this with TCP sockets.

4d824886c8 accel/tcg/cputlb: avoid recursive BQL (fixes #1706296)
The mmio path (see exec.c:prepare_mmio_access) already protects itself
against recursive locking and it makes sense to do the same for
io_readx/writex. Otherwise any helper running in the BQL context will
assert when it attempts to write to device memory as in the case of
the bug report.

33a599667a osdep: Fix ROUND_UP(64-bit, 32-bit)
When using bit-wise operations that exploit the power-of-two
nature of the second argument of ROUND_UP(), we still need to
ensure that the mask is as wide as the first argument (done
by using a ternary to force proper arithmetic promotion).
Unpatched, ROUND_UP(2ULL*1024*1024*1024*1024, 512U) produces 0,
instead of the intended 2TiB, because negation of an unsigned
32-bit quantity followed by widening to 64-bits does not
sign-extend the mask.

Broken since its introduction in commit 292c8e50 (v1.5.0).
Callers that passed the same width type to both macro parameters,
or that had other code to ensure the first parameter's maximum
runtime value did not exceed the second parameter's width, are
unaffected, but I did not audit to see which (if any) existing
clients of the macro could trigger incorrect behavior (I found
the bug while adding a new use of the macro).

While preparing the patch, checkpatch complained about poor
spacing, so I also fixed that here and in the nearby DIV_ROUND_UP.

e90997dc8f 9pfs: fix readdir() for 9p2000.u
If the client is using 9p2000.u, the following occurs:

$ cd ${virtfs_shared_dir}
$ mkdir -p a/b/c
$ ls a/b
ls: cannot access 'a/b/a': No such file or directory
ls: cannot access 'a/b/b': No such file or directory
a  b  c

instead of the expected:

$ ls a/b
c

This is a regression introduced by commit f57f5878578a;
local_name_to_path() now resolves ".." and "." in paths,
and v9fs_do_readdir_with_stat()->stat_to_v9stat() then
copies the basename of the resulting path to the response.
With the example above, this means that "." and ".." are
turned into "b" and "a" respectively...

stat_to_v9stat() currently assumes it is passed a full
canonicalized path and uses it to do two different things:
1) to pass it to v9fs_co_readlink() in case the file is a symbolic
   link
2) to set the name field of the V9fsStat structure to the basename
   part of the given path

It only has two users: v9fs_stat() and v9fs_do_readdir_with_stat().

v9fs_stat() really needs 1) and 2) to be performed since it starts
with the full canonicalized path stored in the fid. It is different
for v9fs_do_readdir_with_stat() though because the name we want to
put into the V9fsStat structure is the d_name field of the dirent
actually (ie, we want to keep the "." and ".." special names). So,
we only need 1) in this case.

This patch hence adds a basename argument to stat_to_v9stat(), to
be used to set the name field of the V9fsStat structure, and moves
the basename logic to v9fs_stat().

83b23fe55c ide: ahci: unparent children buses before freeing their memory
Fixes read after freeing error reported
  https://lists.gnu.org/archive/html/qemu-devel/2017-08/msg04243.html
  Message-Id: <59a56959-ca12-ea75-33fa-ff07eba1b090@redhat.com>

ich9-ahci device creates ide buses and attaches them as QOM children
at realize time, however it forgets to properly clean them up
at unrealize time and frees memory containing these children,
with following call-chain:

   qdev_device_add()
     object_property_set_bool('realized', true)
       device_set_realized()
          ...
          pci_qdev_realize() -> pci_ich9_ahci_realize() -> ahci_realize()
               ...
               s->dev = g_new0(AHCIDevice, ports);
               ...
                  AHCIDevice *ad = &s->dev[i];
                  ide_bus_new(&ad->port, sizeof(ad->port), qdev, i, 1);
                  ^^^ creates bus in memory allocated by above gnew()
                      and adds it as child propety to ahci device
          ...
          hotplug_handler_plug(); -> goto post_realize_fail;
          pci_qdev_unrealize() -> pci_ich9_uninit() -> ahci_uninit()
              ...
               g_free(s->dev);
               ^^^ free memory that holds children busses

          return with error from device_set_realized()

As result later when qdev_device_add() tries to unparent ich9-ahci
after failed device_set_realized(),
    object_unparent() -> object_property_del_child()
iterates over existing QOM children including buses added by
ide_bus_new() and tries to unparent them, which causes access to
freed memory where they where located.

de4ad17a8e hw/arm/digic: Mark device with user_creatable = false
QEMU currently shows some unexpected behavior when the user trys to
do a "device_add digic" on an unrelated ARM machine like integratorcp

later results in a "qemu/qdev-monitor.c:872:qdev_unplug: assertion

Looking at the realize function of the device, it uses serial_hds
directly and this means that the device can not be added a second

tries to do a "device_add s390-ipl" via the monitor later, QEMU aborts with
a "ROM images must be loaded at startup" error message.

d3f05848fc watchdog/wdt_diag288: Mark diag288 watchdog as non-hotpluggable
QEMU currently aborts when the user tries to hot-unplug a diag288
device:

$ qemu-system-s390x -nographic -nodefaults -S -monitor stdio
QEMU 2.9.92 monitor - type 'help' for more information
(qemu) device_add diag288,id=x
(qemu) device_del x
**
ERROR:qemu/qdev-monitor.c:872:qdev_unplug: assertion failed: (hotplug_ctrl)
Aborted (core dumped)

The device is not designed as hot-pluggable (it should only be used
via the "-watchdog" parameter), so let's simply remove the possibility
to hotplug it to prevent that users can run into this ugly situation.

fca5f37fe9 multiboot: validate multiboot header address values
While loading kernel via multiboot-v1 image, (flags & 0x00010000)
indicates that multiboot header contains valid addresses to load
the kernel image. These addresses are used to compute kernel
size and kernel text offset in the OS image. Validate these
address values to avoid an OOB access issue.

This is CVE-2017-14167.

2965be1f00 vga: stop passing pointers to vga_draw_line* functions
Instead pass around the address (aka offset into vga memory).
Add vga_read_* helper functions which apply vbe_size_mask to
the address, to make sure the address stays within the valid
range, similar to the cirrus blitter fixes (commits ffaf857778
and 026aeffcb4).

Impact:  DoS for privileged guest users.  qemu crashes with
a segfault, when hitting the guard page after vga memory
allocation, while reading vga memory for display updates.

b24304ca13 vhost: Release memory references on cleanup
vhost registers a MemoryListener where it adds and removes references
to MemoryRegions as the MemoryRegionSections pass through.  The
region_add callback is invoked for each existing section when the
MemoryListener is registered, but unregistering the MemoryListener
performs no reciprocal region_del callback.  It's therefore the
owner of the MemoryListener's responsibility to cleanup any persistent
changes, such as these memory references, after unregistering.

The consequence of this bug is that if we have both a vhost device
and a vfio device, the vhost device will reference any mmap'd MMIO of
the vfio device via this MemoryListener.  If the vhost device is then
removed, those references remain outstanding.  If we then attempt to
remove the vfio device, it never gets finalized and the only way to
release the kernel file descriptors is to terminate the QEMU process.

65a24b5c44 hw/arm/allwinner-a10: Mark the allwinner-a10 device with user_creatable = false
QEMU currently exits unexpectedly when the user accidentially
tries to do something like this:

$ aarch64-softmmu/qemu-system-aarch64 -S -M integratorcp -nographic
QEMU 2.9.93 monitor - type 'help' for more information
(qemu) device_add allwinner-a10
Unsupported NIC model: smc91c111

Exiting just due to a "device_add" should not happen. Looking closer
at the the realize and instance_init function of this device also
reveals that it is using serial_hds and nd_table directly there, so
this device is clearly not creatable by the user and should be marked
accordingly.

This logic error meant we were not setting the PTZ

168ff32c5d virtfs: error out gracefully when mandatory suboptions are missing
We internally convert -virtfs to -fsdev/-device. If the user doesn't
provide the path or security_model suboptions, and the fsdev backend
requires them, we hit an assertion when populating the internal -fsdev
option:

util/qemu-option.c:547: opt_set: Assertion `opt->str' failed.
Aborted (core dumped)

Let's test the suboption presence on the command line before trying
to set it in the internal -fsdev option, and let the backend code
error out gracefully (ie, like it already does when the user passes
-fsdev on the command line).

QEMU Coding Style
=================
Please use the script checkpatch.pl in the scripts directory to check
patches before submitting.
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 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.
2. 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.
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. 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.
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");
}
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:
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.
5. 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.
6. Conditional statements
When comparing a variable for (in)equality with a constant, list the
constant on the right, as in:
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.
7. 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.
8. trace-events style
8.1 0x prefix
In trace-events files, use a '0x' prefix to specify hex numbers, as in:
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):
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.:
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.
8.2 '#' 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

1. Preprocessor
1.1. Variadic macros
For variadic macros, stick with this C99-like syntax:
#define DPRINTF(fmt, ...) \
do { printf("IRQ: " fmt, ## __VA_ARGS__); } while (0)
1.2. Include directives
Order include directives as follows:
#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.
2. C types
It should be common sense to use the right type, but we have collected
a few useful guidelines here.
2.1. 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.
2.2. 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.
2.3. Typedefs
Typedefs are used to eliminate the redundant 'struct' keyword.
2.4. Reserved namespaces in C and POSIX
Underscore capital, double underscore, and underscore 't' suffixes should be
avoided.
3. 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.
Memory allocated by qemu_memalign or qemu_blockalign must be freed with
qemu_vfree, since breaking this will cause problems on Win32.
4. 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:
void pstrcpy(char *dest, int dest_buf_size, const char *src)
Don't use strcat because it can't check for buffer overflows, but:
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:
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.
5. 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.
6. 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.
7. Error handling and reporting
7.1 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.
7.2 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.
7.3 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().

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:
mkdir build
cd build
../configure
make
Additional information can also be found online via the QEMU website:
http://qemu-project.org/Hosts/Linux
http://qemu-project.org/Hosts/Mac
http://qemu-project.org/Hosts/W32
Submitting patches
==================
The QEMU source code is maintained under the GIT version control system.
git clone git://git.qemu-project.org/qemu.git
When submitting patches, the preferred 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 HACKING and CODING_STYLE files.
Additional information on submitting patches can be found online via
the QEMU website
http://qemu-project.org/Contribute/SubmitAPatch
http://qemu-project.org/Contribute/TrivialPatches
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:
http://qemu-project.org/Contribute/ReportABug
Contact
=======
The QEMU community can be contacted in a number of ways, with the two
main methods being email and IRC
- qemu-devel@nongnu.org
http://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:

Documentation
=============
Documentation can be found hosted online at
`<https://www.qemu.org/documentation/>`_. The documentation for the
current development version that is available at
`<https://www.qemu.org/docs/master/>`_ is generated from the ``docs/``
folder in the source tree, and is built by `Sphinx
<https://www.sphinx-doc.org/en/master/>_`.
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://gitlab.com/qemu-project/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 `style section
<https://www.qemu.org/docs/master/devel/style.html>` of
the Developers Guide.
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://gitlab.com/qemu-project/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.

* License: GNU GPL, version 2 or later.
* See the COPYING file in the top-level directory.
*
* We support instrumentation at an instruction granularity. That is,
* if a plugin wants to instrument the memory accesses performed by a
* particular instruction, it can just do that instead of instrumenting
* all memory accesses. Thus, in order to do this we first have to
* translate a TB, so that plugins can decide what/where to instrument.
*
* Injecting the desired instrumentation could be done with a second
* translation pass that combined the instrumentation requests, but that
* would be ugly and inefficient since we would decode the guest code twice.
* Instead, during TB translation we add "empty" instrumentation calls for all
* possible instrumentation events, and then once we collect the instrumentation
* requests from plugins, we either "fill in" those empty events or remove them
* if they have no requests.
*
* When "filling in" an event we first copy the empty callback's TCG ops. This
* might seem unnecessary, but it is done to support an arbitrary number
* of callbacks per event. Take for example a regular instruction callback.
* We first generate a callback to an empty helper function. Then, if two
* plugins register one callback each for this instruction, we make two copies
* of the TCG ops generated for the empty callback, substituting the function
* pointer that points to the empty helper function with the plugins' desired
* callback functions. After that we remove the empty callback's ops.
*
* Note that the location in TCGOp.args[] of the pointer to a helper function
* varies across different guest and host architectures. Instead of duplicating
* the logic that figures this out, we rely on the fact that the empty
* callbacks point to empty functions that are unique pointers in the program.
* Thus, to find the right location we just have to look for a match in
* TCGOp.args[]. This is the main reason why we first copy an empty callback's
* TCG ops and then fill them in; regardless of whether we have one or many
* callbacks for that event, the logic to add all of them is the same.
*
* When generating more than one callback per event, we make a small
* optimization to avoid generating redundant operations. For instance, for the
* second and all subsequent callbacks of an event, we do not need to reload the
* CPU's index into a TCG temp, since the first callback did it already.
