beb5270034 fix I2C slave addressing
With the recent device handling changes the I2C slave addressing code
was broken. With current code, if a slave with the correct address is

not found on the bus the last scanned slave on the bus will be
addressed. This is wrong. Please find attached a patch to fix it.

3e01c7b93d net: disable draining tap queue in one go
If qemu_send_packet_async() returns zero, it means the packet has been
queued and the sent callback will be invoked once it has been flushed.

This is only possible where the NIC's receive() handler returns zero
and promises to notify the networking core that room is available in its
queue again.

In the case where the receive handler does not have this capability
(and its queue fills up) it returns -1 and the networking core does not
queue up the packet. This condition is indicated by a -1 return from
qemu_send_packet_async().

Currently, tap handles this condition simply by dropping the packet. It
should do its best to avoid getting into this situation by checking such
NIC's have room for a packet before copying the packet from the tap
interface.

tap_send() used to achieve this by only reading a single packet before
returning to the mainloop. That way, tap_can_send() is called before
reading each packet.

tap_send() was changed to completely drain the tap interface queue
without taking into account the situation where the NIC returns an
error and the packet is not queued. Let's start fixing this by
reverting to the previous behaviour of reading one packet at a time.

babd03fde6 usb-linux.c: fix buffer overflow
In usb-linux.c:usb_host_handle_control, we pass a 1024-byte buffer and
length to the kernel.  However, the length was provided by the caller
of dev->handle_packet, and is not checked, so the kernel might provide
too much data and overflow our buffer.

For example, hw/usb-uhci.c could set the length to 2047.
hw/usb-ohci.c looks like it might go up to 4096 or 8192.

This causes a qemu crash, as reported here:
  http://www.mail-archive.com/kvm@vger.kernel.org/msg18447.html

This patch increases the usb-linux.c buffer size to 2048 to fix the
specific device reported, and adds a check to avoid the overflow in
any case.

621cc70bfb RTC polling mode broken
The RTC emulation does not set the IRQ flags independent of the IRQ enable bits.

The original MC146818A datasheet from 1984 notes:
        "flag bits in Register C [...] are set independent of the
        state of the corresponding enable bits in Register B"
Similar sections can be found in newer documentation e.g. in rtc82885.

Qemu and Bochs set the IRQ flags only if they are enabled,
which breaks drivers polling on them.

The following patch corrects this for the update-ended-flag in Qemu only.
It does not fix the handling of the other flags.

ebeab049b0 qcow2: Order concurrent AIO requests on the same unallocated cluster
When two AIO requests write to the same cluster, and this cluster is
unallocated, currently both requests allocate a new cluster and the second one
merges the first one when it is completed. This means an cluster allocation, a
read and a cluster deallocation which cause some overhead. If we simply let the
second request wait until the first one is done, we improve overall performance
with AIO requests (specifially, qcow2/virtio combinations).

This patch maintains a list of in-flight requests that have allocated new
clusters. A second request touching the same cluster is limited so that it
either doesn't touch the allocation of the first request (so it can have a
non-overlapping allocation) or it waits for the first request to complete.

currently the vga screen_dump code doesn't use the DisplayState

52668cf7b3 sdl.c: support 32 bpp cursors
Hello,
currently when a 32 bpp cursor gets defined the result is all-black in
the areas that are not transparent (you'll get a 32 bpp cursor if you
use my previous patch to allow vmware_vga to use a 32 bpp framebuffer).
This is because the switch in sdl.c lacks a 32 bpp case.
The thing I am unsure about though is which byte is the unused one and
should be skipped, the first or the last - for the black-and-white
cursors I tested it doesn't make a difference...

for what I can tell, there is no way for vmware_vga to work correctly

with the current version of DisplaySurface.

b0f6d6c744 make windows notice media change
Windows seems to be very stupid about cdrom media change. It polls
cdrom status and if status goes ready->media not present->ready
it assumes that media was changed. If "media not present" step doesn't
happen even if "medium may have changed" was seen it assumes media
haven't changed. Fake "media not present" step.

Filip Navara did a great job debugging this issue in Windows and this is
what he found out:

BINGO! ... The media present notifications were broken ever since
Windows 2000 it seems. The media change is detected properly and it's
passed to ClassSetMediaChangeState function which in turn calls
ClasspInternalSetMediaChangeState. This function is responsible for
changing some internal state of the device object and sending the PnP
events which later result in application notifications. It has this
tiny bit of code (not copied byte for byte):

if (oldMediaState == NewState) {
  // Media is in the same state it was before.
  return;
}

so the end result is that for the case of UNIT NEEDS ATTENTION /
MEDIUM MAY HAVE CHANGED without NOT READY in-between is really broken.
It results in the internal media change counter incremented, so the
media contents are re-read when necessary, instead of relying on the
cache, but the notifications to applications are never sent.

cfd28938fc e1000.c doesn't properly emulate EERD and ICS registers
Once again, the emulation of the EERD and ICS registers in e1000.c is
incorrect. Nobody has noticed this before because none of the Intel-written
e1000 drivers use these registers, and all of the independently written open
source drivers copy Intel's example, so they don't use them either.
Regardless, these registers are documented in the programmer's manuals, and
their emulated behavior doesn't match the verified behavior of real hardware,
so any software that does use them doesn't function correctly.

9d61a50bdd Fix VM state change handlers running out of order
When a VM state change handler changes VM state, other VM state change
handlers can see the state transitions out of order.

bmdma_map(), scsi_disk_init() and virtio_blk_init() install VM state
change handlers to restart DMA.  These handlers can vm_stop() by
running into a write error on a drive with werror=stop.  This throws
the VM state change handler callback into disarray.  Here's an example
case I observed:

0. The virtual IDE drive goes south.  All future writes return errors.

1. Something encounters a write error, and duly stops the VM with
   vm_stop().

2. vm_stop() calls vm_state_notify(0).

3. vm_state_notify() runs the callbacks in list vm_change_state_head.
   It contains ide_dma_restart_cb() installed by bmdma_map().  It also
   contains audio_vm_change_state_handler() installed by audio_init().

4. audio_vm_change_state_handler() stops audio stuff.

5. User continues VM with monitor command "c".  This runs vm_start().

6. vm_start() calls vm_state_notify(1).

7. vm_state_notify() runs the callbacks in vm_change_state_head.

8. ide_dma_restart_cb() happens to come first.  It does its work, runs
   into a write error, and duly stops the VM with vm_stop().

9. vm_stop() runs vm_state_notify(0).

10. vm_state_notify() runs the callbacks in vm_change_state_head.

11. audio_vm_change_state_handler() stops audio stuff.  Which isn't
   running.

12. vm_stop() finishes, ide_dma_restart_cb() finishes, step 7's
   vm_state_notify() resumes running handlers.

13. audio_vm_change_state_handler() starts audio stuff.  Oopsie.

Fix this by moving the actual write from each VM state change handler
into a new bottom half (suggested by Gleb Natapov).

96bc323100 target-mips: fix conditional moves off fp condition codes
Conditional moves off fp condition codes were using the result of
get_fp_bit to isolate and test the relevant condition code.  However,
get_fp_bit returns the bit number of the condition code, not a
bitmask.  (Compare the use of get_fp_bit in gen_compute_branch1, for
instance.)

Fixed by shifting a bitmask into place using the result of get_fp_bit in
the relevant functions (gen_mov{ci,cf_s,cf_d,cf_ps}).

b87d79698d HPET fixes for reg writes
This patch addresses the problems found by Andriy Gapon:

- The code was incorrectly overwriting the high order 32
  bits of the timer and hpet config registers. This didn't show up
  in testing because linux and windows use hpet in legacy mode,
  where the high order 32 bits (advertising available interrupts)
  of the timer config register are ignored, and the high order 32
  bits of the hpet config register are reserved and unused.

- The mask for level-triggered interrupts was off by a bit. (hpet
  doesn't currently support level-triggered interrupts).

In addition, I removed some unused #defines, and corrected the ioapic
interrupt values advertised. I'd set this up early in hpet development
and never went back to correct it, and no bugs resulted since linux and
windows use hpet in legacy mode where available interrupts are ignored.

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

QEMU Coding Style

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

===========
QEMU 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>`_

General:
-------
- cycle counter for all archs
- cpu_interrupt() win32/SMP fix
- merge PIC spurious interrupt patch
- warning for OS/2: must not use 128 MB memory (merge bochs cmos patch ?)
- config file (at least for windows/Mac OS X)
- update doc: PCI infos.
- basic VGA optimizations
- better code fetch
- do not resize vga if invalid size.
- TLB code protection support for PPC
- disable SMC handling for ARM/SPARC/PPC (not finished)
- see undefined flags for BTx insn
- keyboard output buffer filling timing emulation
- tests for each target CPU
- fix all remaining thread lock issues (must put TBs in a specific invalid
state, find a solution for tb_flush()).
ppc specific:
------------
- TLB invalidate not needed if msr_pr changes
- enable shift optimizations ?
linux-user specific:
-------------------
- remove threading support as it cannot work at this point
- improve IPC syscalls
- more syscalls (in particular all 64 bit ones, IPCs, fix 64 bit
issues, fix 16 bit uid issues)
- use kernel traps for unaligned accesses on ARM ?
lower priority:
--------------
- int15 ah=86: use better timing
- use -msoft-float on ARM

* 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.
