cc0bd7ec83 wdt_i6300esb: fix vmstate versioning
When this VMSD was introduced it's version fields were set to
sizeof(I6300State), making them essentially random from build to build,
version to version.

To fix this, we lock in a high version id and low minimum version id to
support old->new migration from all prior versions of this device's
state. This should work since the device state has not changed since
its introduction.

The potentially breaks migration from 1.5+ to 1.5, but since the
versioning was essentially random prior to this patch, new->old
migration was not consistently functional to begin with.

9c4f5dd03a scsi-generic: fix sign extension of READ CAPACITY(10) data
Issuing the READ CAPACITY(10) command in the guest will cause QEMU
to update its knowledge of the maximum accessible LBA in the disk.
The recorded maximum LBA will be wrong if the disk is bigger than
1TB, because ldl_be_p returns a signed int.

When this is fixed, a latent bug will be unmasked.  If the READ
CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must
not overwrite the previously-known maximum accessible LBA, or the guest
will fail to access the disk above the first 2TB.

3abd71cd98 scsi: reset cdrom tray statuses on scsi_disk_reset
Tray statuses should be also reset. Some guests may lock the tray and
right after resetting the guest it should be unlocked and closed. This
is done on power-on, reset and resume from suspend/hibernate on bare-metal.

This fix is already committed for IDE CD.
Check the commit a7f3d65b65.

Test results on bare-metal:
  - on reset/power-on the CD-ROM tray is closed even before the monitor
    is turned on
  - on resume from suspend/hibernate the tray is also closed before
    the monitor is turned on

From test results it seems that this behavior is OS and probably BIOS
independent.

2) vhostfds were specified but fds were not specified

monitor_handle_fd_param(), which may crash the qemu.

Also remove the unnecessary has_fd check.

0817fa9767 create qemu_openpty_raw() helper function and move it to a separate file
In two places qemu uses openpty() which is very system-dependent,
and in both places the pty is switched to raw mode as well.
Make a wrapper function which does both steps, and move all the
system-dependent complexity into a separate file, together
with static/local implementations of openpty() and cfmakeraw()
from qemu-char.c.

It is in a separate file, not part of oslib-posix.c, because
openpty() often resides in -lutil which is not linked to
every program qemu builds.

This change removes #including of <pty.h>, <termios.h>
and other rather specific system headers out of qemu-common.h,
which isn't a place for such specific headers really.

This version has been verified to build correctly on Linux,
OpenBSD, FreeBSD and OpenIndiana.  On the latter it lets qemu
to be built with gtk gui which were not possible there due to
missing openpty() and cfmakeraw().

5810174865 blockdev: reset werror/rerror on drive_del
Paolo Bonzini <pbonzini@redhat.com> suggested the following test case:

1. Launch a guest and wait at the GRUB boot menu:

  qemu-system-x86_64 -enable-kvm -m 1024 \
   -drive if=none,cache=none,file=test.img,id=foo,werror=stop,rerror=stop
   -device virtio-blk-pci,drive=foo,id=virtio0,addr=4

2. Hot unplug the device:

  (qemu) drive_del foo

3. Select the first boot menu entry

Without this patch the guest pauses due to ENOMEDIUM.  The guest is
stuck in a continuous pause loop since the I/O request is retried and
fails immediately again when the guest is resumed.

With this patch the error is reported to the guest.

Note that this scenario actually happens sometimes during libvirt disk
hot unplug, where device_del is followed by drive_del.  I/O may still be
submitted to the drive after drive_del if the guest does not process the
PCI hot unplug notification.

eeaa8d33e4 q35: set fw_name
PCI host bridges need to set fw_name to be discoverable
by bios for boot device selection.

In particular, seabios expects root device to be called
"/pci/@i0cf8", so let's set it up like that for Q35.

c1270701c0 target-i386: Fix aflag logic for CODE64 and the 0x67 prefix
The code reorganization in commit 4a6fd938 broke handling of PREFIX_ADR.
While fixing this, tidy and comment the code so that it's more obvious
what's going on in setting both aflag and dflag.

The TARGET_X86_64 ifdef can be eliminated because CODE64 expands to the
constant zero when TARGET_X86_64 is undefined.

252a7c6e11 qemu-char: don't issue CHR_EVENT_OPEN in a BH
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET,
and it was issued as a bottom-half:

86e94dea5b

Which we basically used to print out a greeting/prompt for the
monitor.

AFAICT the only reason this was ever done in a BH was because in
some cases we'd modify the chr_write handler for a new chardev
backend *after* the site where we issued the reset (see:
86e94d:qemu_chr_open_stdio())

At some point this event was renamed to CHR_EVENT_OPENED, and we've
maintained the use of this BH ever since.

However, due to 9f939df955, we schedule
the BH via g_idle_add(), which is causing events to sometimes be
delivered after we've already begun processing data from backends,
leading to:

 known bugs:

  QMP:
    session negotation resets with OPENED event, in some cases this
    is causing new sessions to get sporadically reset

 potential bugs:

  hw/usb/redirect.c:
    can_read handler checks for dev->parser != NULL, which may be
    true if CLOSED BH has not been executed yet. In the past, OPENED
    quiesced outstanding CLOSED events prior to us reading client
    data. If it's delayed, our check may allow reads to occur even
    though we haven't processed the OPENED event yet, and when we
    do finally get the OPENED event, our state may get reset.

  qtest.c:
    can begin session before OPENED event is processed, leading to
    a spurious reset of the system and irq_levels

  gdbstub.c:
    may start a gdb session prior to the machine being paused

To fix these, let's just drop the BH.

Since the initial reasoning for using it still applies to an extent,
work around that by deferring the delivery of CHR_EVENT_OPENED until
after the chardevs have been fully initialized, toward the end of
qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This
defers delivery long enough that we can be assured a CharDriverState
is fully initialized before CHR_EVENT_OPENED is sent.

Also, rather than requiring each chardev to do an explicit open, do it
automatically, and allow the small few who don't desire such behavior to
suppress the OPENED-on-init behavior by setting a 'explicit_be_open'
flag.

We additionally add missing OPENED events for stdio backends on w32,
which were previously not being issued, causing us to not recieve the
banner and initial prompts for qmp/hmp.

032ce1baac qdev: fix get_fw_dev_path to support to add nothing to fw_dev_path
Recent virtio refactoring in QEMU made virtio-bus become the parent bus
of scsi-bus, and virtio-bus doesn't have get_fw_dev_path implementation,
typename will be added to fw_dev_path by default, the new fw_dev_path
could not be identified by seabios. It causes that bootindex parameter
of scsi device doesn't work.

This patch implements get_fw_dev_path() in BusClass, it will be called
if bus doesn't implement the method, tyename will be added to
fw_dev_path. If the implemented method returns NULL, nothing will be
added to fw_dev_path.

It also implements virtio_bus_get_fw_dev_path() to return NULL. Then
QEMU will still pass original style of fw_dev_path to seabios.

d503afb28d target-i386: fix abort on bad PML4E/PDPTE/PDE/PTE addresses
The code used to walk IA-32e page-tables, and possibly PAE page-tables,
uses the bit mask ~0xfff to get the next PML4E/PDPTE/PDE/PTE address.

However, as we use a uint64_t to store the resulting address, that mask
gets expanded to 0xfffffffffffff000 which not only ends up selecting
reserved bits but also selects the XD bit (execute-disable) which
happens to be enabled by Windows 8, causing qemu_get_ram_ptr() to abort.

This commit fixes that problem by replacing ~0xfff by a correct mask
that only selects the address bit range (ie. bits 51:12).

0565700d78 ide: Set BSY bit during FLUSH
The implementation of the ATA FLUSH command invokes a flush at the block
layer, which may on raw files on POSIX entail a synchronous fdatasync().
This may in some cases take so long that the SLES 11 SP1 guest driver
reports I/O errors and filesystems get corrupted or remounted read-only.

Avoid this by setting BUSY_STAT, so that the guest is made aware we are
in the middle of an operation and no ATA commands are attempted to be
processed concurrently.

Addresses BNC#637297.

38ec6c1071 xen_machine_pv: do not create a dummy CPU in machine->init
This fixes a regression introduced by:

commit 62fc403f11
Author: Igor Mammedov <imammedo@redhat.com>
Date:   Mon Apr 29 18:54:13 2013 +0200

    target-i386: Attach ICC bus to CPU on its creation

    X86CPU should have parent bus so it could provide bus for child APIC.

The commit makes it mandatory to pass a valid ICC bus to cpu_x86_create,
but cpu_x86_init just passes NULL to it.
xen_machine_pv uses cpu_x86_init, therefore it has been broken.

This patch fixes the problem by removing the dummy CPU creation
altogether from xen_init_pv, relying on the fact that QEMU can now cope
with a machine without an emulated CPU.

749806d1a7 rtl8139: flush queued packets when RxBufPtr is written
Net queues support efficient "receive disable".  For example, tap's file
descriptor will not be polled while its peer has receive disabled.  This
saves CPU cycles for needlessly copying and then dropping packets which
the peer cannot receive.

rtl8139 is missing the qemu_flush_queued_packets() call that wakes the
queue up when receive becomes possible again.

As a result, the Windows 7 guest driver reaches a state where the
rtl8139 cannot receive packets.  The driver has actually refilled the
receive buffer but we never resume reception.

The bug can be reproduced by running a large FTP 'get' inside a Windows
7 guest:

  $ qemu -netdev tap,id=tap0,...
         -device rtl8139,netdev=tap0

The Linux guest driver does not trigger the bug, probably due to a
different buffer management strategy.

# 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

# 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>

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 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

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.

QEMU Coding Style

patches before submitting.
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

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)

QEMU Monitor Protocol
=====================
Introduction
-------------
The QEMU Monitor Protocol (QMP) allows applications to communicate with
QEMU's Monitor.
QMP is JSON[1] based and currently has the following features:
- Lightweight, text-based, easy to parse data format
- Asynchronous messages support (ie. events)
- Capabilities Negotiation
For detailed information on QMP's usage, please, refer to the following files:
o qmp-spec.txt QEMU Monitor Protocol current specification
o qmp-commands.txt QMP supported commands (auto-generated at build-time)
o qmp-events.txt List of available asynchronous events
There is also a simple Python script called 'qmp-shell' available.
IMPORTANT: It's strongly recommended to read the 'Stability Considerations'
section in the qmp-commands.txt file before making any serious use of QMP.
[1] http://www.json.org
Usage
-----
To enable QMP, you need a QEMU monitor instance in "control mode". There are
two ways of doing this.
The simplest one is using the '-qmp' command-line option. The following
example makes QMP available on localhost port 4444:
$ qemu [...] -qmp tcp:localhost:4444,server
However, in order to have more complex combinations, like multiple monitors,
the '-mon' command-line option should be used along with the '-chardev' one.
For instance, the following example creates one user monitor on stdio and one
QMP monitor on localhost port 4444.
$ qemu [...] -chardev stdio,id=mon0 -mon chardev=mon0,mode=readline \
-chardev socket,id=mon1,host=localhost,port=4444,server \
-mon chardev=mon1,mode=control
Please, refer to QEMU's manpage for more information.
Simple Testing
--------------
To manually test QMP one can connect with telnet and issue commands by hand:
$ telnet localhost 4444
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
{"QMP": {"version": {"qemu": {"micro": 50, "minor": 13, "major": 0}, "package": ""}, "capabilities": []}}
{ "execute": "qmp_capabilities" }
{"return": {}}
{ "execute": "query-version" }
{"return": {"qemu": {"micro": 50, "minor": 13, "major": 0}, "package": ""}}
Development Process
-------------------
When changing QMP's interface (by adding new commands, events or modifying
existing ones) it's mandatory to update the relevant documentation, which is
one (or more) of the files listed in the 'Introduction' section*.
Also, it's strongly recommended to send the documentation patch first, before
doing any code change. This is so because:
1. Avoids the code dictating the interface
2. Review can improve your interface. Letting that happen before
you implement it can save you work.
* The qmp-commands.txt file is generated from the qmp-commands.hx one, which
is the file that should be edited.

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
ready for capabilities negotiation (for more information refer to section
'4. Capabilities Negotiation').
The format is:
{ "QMP": { "version": json-object, "capabilities": json-array } }
Where,
- The "version" member contains the Server's version information (the format
is the same of the 'query-version' command)
- 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, "desc": json-string }, "id": json-value }
Where,
- The "class" member contains the error class name (eg. "GenericError")
- 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": {"version": {"qemu": "0.12.50", "package": ""}, "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": "GenericError", "desc": "Invalid JSON syntax" } }
3.5 Powerdown event
-------------------
S: {"timestamp": {"seconds": 1258551470, "microseconds": 802384}, "event":
"POWERDOWN"}
4. Capabilities Negotiation
----------------------------
When a Client successfully establishes a connection, the Server is in
Capabilities Negotiation mode.
In this mode only the 'qmp_capabilities' command is allowed to run, all
other commands will return the CommandNotFound error. Asynchronous messages
are not delivered either.
Clients should use the 'qmp_capabilities' command to enable capabilities
advertised in the Server's greeting (section '2.2 Server Greeting') they
support.
When the 'qmp_capabilities' command is issued, and if it does not return an
error, the Server enters in Command mode where capabilities changes take
effect, all commands (except 'qmp_capabilities') are allowed and asynchronous
messages are delivered.
5 Compatibility Considerations
------------------------------
All protocol changes or new features which modify the protocol format in an
incompatible way are disabled by default and will be advertised by the
capabilities array (section '2.2 Server Greeting'). Thus, Clients can check
that array and enable the capabilities they support.
The QMP Server performs a type check on the arguments to a command. It
generates an error if a value does not have the expected type for its
key, or if it does not understand a key that the Client included. The
strictness of the Server catches wrong assumptions of Clients about
the Server's schema. Clients can assume that, when such validation
errors occur, they will be reported before the command generated any
side effect.
However, Clients must not assume any particular:
- Length of json-arrays
- Size of json-objects; in particular, future versions of QEMU may add
new keys and Clients should be able to ignore them.
- 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
Of course, the Server does guarantee to send valid JSON. But apart from
this, a Client should be "conservative in what they send, and liberal in
what they accept".
6. Downstream extension of QMP
------------------------------
We recommend that downstream consumers of QEMU do *not* modify QMP.
Management tools should be able to support both upstream and downstream
versions of QMP without special logic, and downstream extensions are
inherently at odds with that.
However, we recognize that it is sometimes impossible for downstreams to
avoid modifying QMP. Both upstream and downstream need to take care to
preserve long-term compatibility and interoperability.
To help with that, QMP reserves JSON object member names beginning with
'__' (double underscore) for downstream use ("downstream names"). This
means upstream will never use any downstream names for its commands,
arguments, errors, asynchronous events, and so forth.
Any new names downstream wishes to add must begin with '__'. To
ensure compatibility with other downstreams, it is strongly
recommended that you prefix your downstram names with '__RFQDN_' where
RFQDN is a valid, reverse fully qualified domain name which you
control. For example, a qemu-kvm specific monitor command would be:
(qemu) __org.linux-kvm_enable_irqchip
Downstream must not change the server greeting (section 2.2) other than
to offer additional capabilities. But see below for why even that is
discouraged.
Section '5 Compatibility Considerations' applies to downstream as well
as to upstream, obviously. It follows that downstream must behave
exactly like upstream for any input not containing members with
downstream names ("downstream members"), except it may add members
with downstream names to its output.
Thus, a client should not be able to distinguish downstream from
upstream as long as it doesn't send input with downstream members, and
properly ignores any downstream members in the output it receives.
Advice on downstream modifications:
1. Introducing new commands is okay. If you want to extend an existing
command, consider introducing a new one with the new behaviour
instead.
2. Introducing new asynchronous messages is okay. If you want to extend
an existing message, consider adding a new one instead.
3. Introducing new errors for use in new commands is okay. Adding new
errors to existing commands counts as extension, so 1. applies.
4. New capabilities are strongly discouraged. Capabilities are for
evolving the basic protocol, and multiple diverging basic protocol
dialects are most undesirable.

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>`_

* 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.
