Paolo Bonzini 58803ce74f test-coroutine: add baseline test that times the cost of function calls
This can be used to compute the cost of coroutine operations.  In the
end the cost of the function call is a few clock cycles, so it's pretty
cheap for now, but it may become more relevant as the coroutine code
is optimized.

For example, here are the results on my machine:

   Function call 100000000 iterations: 0.173884 s
   Yield 100000000 iterations: 8.445064 s
   Lifecycle 1000000 iterations: 0.098445 s
   Nesting 10000 iterations of 1000 depth each: 7.406431 s

One yield takes 83 nanoseconds, one enter takes 97 nanoseconds,
one coroutine allocation takes (roughly, since some of the allocations
in the nesting test do hit the pool) 739 nanoseconds:

   (8.445064 - 0.173884) * 10^9 / 100000000 = 82.7
   (0.098445 * 100 - 0.173884) * 10^9 / 100000000 = 96.7
   (7.406431 * 10 - 0.173884) * 10^9 / 100000000 = 738.9

Paolo Bonzini acd727e7cb acpi-dsdt: procedurally generate _PRT
This replaces the _PRT constant with a method that computes it.

The problem is that the DSDT+SSDT have grown from 2.0 to 2.1,
enough to cross the 8k barrier (we align the ACPI tables to 4k
before putting them in fw_cfg).  This causes problems with
migration and the pc-i440fx-2.0 machine type.

The solution to the problem is to hardcode 64k as the limit,
but this doesn't solve the bug with pc-i440fx-2.0.  The fix will be
for QEMU 2.1 to use exactly the same size as QEMU 2.0 for the
ACPI tables.  First, however, we must make the actual AML
equal or smaller; to do this, rewrite _PRT in a way that saves
over 1k of bytecode.

Stefan Hajnoczi 8283c5c316 qemu-iotests: fix 028 failure due to disk image path
The disk image path is echoed by QEMU's readline when the "drive_backup
disk ${TEST_IMG}.copy" HMP command is issued.  Unfortunately it is very
hard to filter out the path due to readline's character-by-character
output (with terminal escape sequences).  Just redirect this command to
/dev/null for now.

Kevin Wolf 12ac6d3db7 qcow2: Fix error path for unknown incompatible features
qcow2's report_unsupported_feature() had two bugs: A 32 bit truncation
would prevent feature table entries for bits 32-63 from being used, and
it could assign errp multiple times if there was more than one unknown

Fix the truncation, make sure to set the error exactly once and add a
qemu-iotests case for it.

Paolo Bonzini acfb23ad3d AioContext: do not rely on aio_poll(ctx, true) result to end a loop
Currently, whenever aio_poll(ctx, true) has completed all pending
work it returns true *and* the next call to aio_poll(ctx, true)
will not block.

This invariant has its roots in qemu_aio_flush()'s implementation
as "while (qemu_aio_wait()) {}".  However, qemu_aio_flush() does
not exist anymore and bdrv_drain_all() is implemented differently;
and this invariant is complicated to maintain and subtly different
from the return value of GMainLoop's g_main_context_iteration.

All calls to aio_poll(ctx, true) except one are guarded by a
while() loop checking for a request to be incomplete, or a
BlockDriverState to be idle.  The one remaining call (in
iothread.c) uses this to delay the aio_context_release/acquire
pair until the AioContext is quiescent, however:

- we can do the same just by using non-blocking aio_poll,
  similar to how vl.c invokes main_loop_wait

- it is buggy, because it does not ensure that the AioContext
  is released between an aio_notify and the next time the
  iothread goes to sleep.  This leads to hangs when stopping
  the dataplane thread.

In the end, these semantics are a bad match for the current
users of AioContext.  So modify that one exception in iothread.c,
which also fixes the hangs, as well as the testcase so that
it use the same idiom as the actual QEMU code.

Kevin Wolf d40593dd90 block/backup: Fix hang for unaligned image size
When doing a block backup of an image with an unaligned size (with
respect to the BACKUP_CLUSTER_SIZE), qemu would check the allocation
status of sectors after the end of the image. bdrv_is_allocated()
returns a result that is valid for 0 sectors in this case, so the backup
job ran into an endless loop.

Stop looping when seeing a result valid for 0 sectors, we're at EOF then.

The test case looks somewhat unrelated at first sight because I
originally tried to reproduce a different suspected bug that turned out
to not exist. Still a good test case and it accidentally found this one.

Paolo Bonzini 563890c7c7 libqtest: escape strings in QMP commands, fix leak
libqtest is using g_strdup_printf to format QMP commands, but
this does not work if the argument strings need to be escaped.
Instead, use the fancy %-formatting functionality of QObject.
The only change required in tests is that strings have to be
formatted as %s, not '%s' or \"%s\".  Luckily this usage of
parameterized QMP commands is not that frequent.

The leak is in socket_sendf.  Since we are extracting the send
loop to a new function, fix it now.

Chunyan Liu 4ab1559085 qemu-img create: add 'nocow' option
Add 'nocow' option so that users could have a chance to set NOCOW flag to
newly created files. It's useful on btrfs file system to enhance performance.

Btrfs has low performance when hosting VM images, even more when the guest
in those VM are also using btrfs as file system. One way to mitigate this bad
performance is to turn off COW attributes on VM files. Generally, there are
two ways to turn off NOCOW on btrfs: a) by mounting fs with nodatacow, then
all newly created files will be NOCOW. b) per file. Add the NOCOW file
attribute. It could only be done to empty or new files.

This patch tries the second way, according to the option, it could add NOCOW
per file.

For most block drivers, since the create file step is in raw-posix.c, so we
can do setting NOCOW flag ioctl in raw-posix.c only.

But there are some exceptions, like block/vpc.c and block/vdi.c, they are
creating file by calling qemu_open directly. For them, do the same setting
NOCOW flag ioctl work in them separately.

iotest 083 filters out debug messages from nbd, which are prefixed (and
recognized) by __FILE__. However, the current filter (/^nbd\.c…/) is
valid for in-tree builds only, as out-of-tree builds will have a path
before that filename (e.g. "/tmp/qemu/nbd.c"). Fix this by adding .*
before "nbd\.c".

While working on this, also fix the regexes: '.' should be escaped and a

Max Reitz e8f8624d3b iotests: Allow out-of-tree run
As out-of-tree builds are preferred for qemu, running the qemu-iotests
in that out-of-tree build should be supported as well. To do so, a
symbolic link has to be created pointing to the check script in the
source directory. That script will check whether it has been run through
a symlink, and if so, will assume it is run in the build tree. All
output and temporary operations performed by iotests are then redirected
here and, unless specified otherwise by the user, QEMU_PROG etc. will be
set to paths appropriate for the build tree.

Also, drop making every test case executable if it is not yet, as this
would modify the source tree which is not desired for out-of-tree runs
and should be fixed in the repository anyway.
