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

A. HISTORY OF THE SOFTWARE
|
||||
==========================
|
||||
|
||||
Python was created in the early 1990s by Guido van Rossum at Stichting
|
||||
Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
|
||||
as a successor of a language called ABC. Guido remains Python's
|
||||
principal author, although it includes many contributions from others.
|
||||
|
||||
In 1995, Guido continued his work on Python at the Corporation for
|
||||
National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
|
||||
in Reston, Virginia where he released several versions of the
|
||||
software.
|
||||
|
||||
In May 2000, Guido and the Python core development team moved to
|
||||
BeOpen.com to form the BeOpen PythonLabs team. In October of the same
|
||||
year, the PythonLabs team moved to Digital Creations (now Zope
|
||||
Corporation, see http://www.zope.com). In 2001, the Python Software
|
||||
Foundation (PSF, see http://www.python.org/psf/) was formed, a
|
||||
non-profit organization created specifically to own Python-related
|
||||
Intellectual Property. Zope Corporation is a sponsoring member of
|
||||
the PSF.
|
||||
|
||||
All Python releases are Open Source (see http://www.opensource.org for
|
||||
the Open Source Definition). Historically, most, but not all, Python
|
||||
releases have also been GPL-compatible; the table below summarizes
|
||||
the various releases.

|
||||
Footnotes:
|
||||
|
||||
(1) GPL-compatible doesn't mean that we're distributing Python under
|
||||
the GPL. All Python licenses, unlike the GPL, let you distribute
|
||||
a modified version without making your changes open source. The
|
||||
GPL-compatible licenses make it possible to combine Python with
|
||||
other software that is released under the GPL; the others don't.
|
||||
|
||||
(2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
|
||||
because its license has a choice of law clause. According to
|
||||
CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
|
||||
is "not incompatible" with the GPL.
|
||||
|
||||
Thanks to the many outside volunteers who have worked under Guido's
|
||||
direction to make these releases possible.

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
|
||||
===========
|
||||
The QEMU x86 emulator
|
||||
---------------------
|
||||
|
||||
QEMU is a generic and open source machine & userspace emulator and
|
||||
virtualizer.
|
||||
INSTALLATION
|
||||
------------
|
||||
|
||||
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).
|
||||
Type
|
||||
|
||||
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.
|
||||
./configure
|
||||
make
|
||||
|
||||
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.
|
||||
to build qemu, qemu-CPU and libqemu.a (CPU is the name of the various
|
||||
supported target CPUs).
|
||||
|
||||
QEMU as a whole is released under the GNU General Public License,
|
||||
version 2. For full licensing details, consult the LICENSE file.
|
||||
Type
|
||||
|
||||
make install
|
||||
|
||||
to install QEMU in /usr/local
|
||||
|
||||
Tested tool versions
|
||||
--------------------
|
||||
|
||||
In order to compile QEMU succesfully, it is very important that you
|
||||
have the right tools. The most important one is gcc. I cannot guaranty
|
||||
that QEMU works if you do not use a tested gcc version. Look at
|
||||
'configure' and 'Makefile' if you want to make a different gcc
|
||||
version work.
|
||||
|
||||

[1] On Alpha, QEMU needs the gcc 'visibility' attribute only available
|
||||
for gcc version >= 3.3.
|
||||
[2] Linux >= 2.4.20 is necessary for precise exception support
|
||||
(untested).
|
||||
[3] 2.4.9-ac10-rmk2-np1-cerf2
|
||||
|
||||
[4] gcc 2.95.x generates invalid code when using too many register
|
||||
variables. You must use gcc 3.x on PowerPC.

Documentation
|
||||
-------------
|
||||
|
||||
Read the documentation in qemu-doc.html.
|
||||
|
||||
|
||||
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:
|
||||
|
||||
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.
|
||||
|
||||
git clone git://git.qemu.org/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 HACKING and CODING_STYLE files.
|
||||
|
||||
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.
|
||||
|
||||
git clone git://git.qemu.org/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:
|
||||
|
||||
$ 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:
|
||||
|
||||
$ 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
|
||||
|
||||
- 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:

short term:
|
||||
----------
|
||||
- physical memory cache (reduce qemu-fast address space size to about 32 MB)
|
||||
- better code fetch (different exception handling + CS.limit support)
|
||||
- do not resize vga if invalid size.
|
||||
- avoid looping if only exceptions
|
||||
- handle fast timers + add explicit clocks
|
||||
- cycle counter for all archs
|
||||
- TLB code protection support for PPC
|
||||
- add sysenter/sysexit and fxsr for L4 pistachio 686
|
||||
- basic VGA optimizations
|
||||
- disable SMC handling for ARM/SPARC/PPC (not finished)
|
||||
- see undefined flags for BTx insn
|
||||
- user/kernel PUSHL/POPL in helper.c
|
||||
- keyboard output buffer filling timing emulation
|
||||
- return UD exception if LOCK prefix incorrectly used
|
||||
- test ldt limit < 7 ?
|
||||
- tests for each target CPU
|
||||
- fix CCOP optimisation
|
||||
- fix all remaining thread lock issues (must put TBs in a specific invalid
|
||||
state, find a solution for tb_flush()).
|
||||
- fix arm fpu rounding (at least for float->integer conversions)
|
||||
- SMP support
|
||||
|
||||
lower priority:
|
||||
--------------
|
||||
- HDD geometry in CMOS (not used except for very old DOS programs)
|
||||
- suppress shift_mem ops
|
||||
- fix some 16 bit sp push/pop overflow (pusha/popa, lcall lret)
|
||||
- sysenter/sysexit emulation
|
||||
- optimize FPU operations (evaluate x87 stack pointer statically)
|
||||
- add IPC syscalls
|
||||
- use -msoft-float on ARM
|
||||
- use kernel traps for unaligned accesses on ARM ?
|
||||
- handle rare page fault cases (in particular if page fault in heplers or
|
||||
in syscall emulation code).
|
||||
- fix thread stack freeing (use kernel 2.5.x CLONE_CHILD_CLEARTID)
|
||||
- more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
|
||||
issues, fix 16 bit uid issues)
|
||||
- use page_unprotect_range in every suitable syscall to handle all
|
||||
cases of self modifying code.
|
||||
- use gcc as a backend to generate better code (easy to do by using
|
||||
op-i386.c operations as local inline functions).
|
||||
- add SSE2/MMX operations
