c2f3029fbc ahci: Add test_hba_spec to ahci-test.
Add a test routine that checks the boot-up values of the HBA
configuration memory space against the AHCI 1.3 specification
and Intel ICH9 data sheet (for Q35 machines) for adherence and
sane values.

The HBA is not yet engaged or put into the idle state.

[Replaced g_assert_false(...) with g_assert(!...) for glib <2.38
compatibility, reported by Peter Maydell <peter.maydell@linaro.org>.

96d6d3bad9 ahci: add test_pci_enable to ahci-test.
This adds a test wherein we engage the PCI AHCI
device and ensure that the memory region for the
HBA functionality is now accessible.

Under Q35 environments, additional PCI configuration
is performed to ensure that the HBA functionality
will become usable.

8840a843dc ahci: Add test_pci_spec to ahci-test.
Adds a specification adherence test for AHCI
where the boot-up values for the PCI configuration space
are compared against the AHCI 1.3 specification.

This test does not itself attempt to engage the device.

1cd1031ddc ahci: Adding basic functionality qtest.
Currently, there is no qtest to test the functionality of
the AHCI functionality present within the Q35 machine type.

This patch adds a skeleton for an AHCI test suite,
and adds a simple sanity-check test case where we
identify that the AHCI device is present, then
disengage the virtual machine.

3391f5e51c thread-pool: Convert thread_pool_aiocb_info.cancel to cancel_async
The .cancel_async shares the same the first half with .cancel: try to
steal the request if not submitted yet. In this case set the elem to
THREAD_DONE status and ret to -ECANCELED, which means
thread_pool_completion_bh will call the cb with -ECANCELED.

If the request is already submitted, do nothing, as we know the normal
completion will happen in the future.

Testing code update:

Before, done_cb is only called if the request is already submitted by
thread pool. Now done_cb is always called, even before it is submitted,
because we emulate bdrv_aio_cancel with bdrv_aio_cancel_async. So also
update the test criteria accordingly.

b3ce84fea4 qdev: Move global validation to a single function
Currently GlobalProperty.not_used=false has multiple meanings:

* It may be a property for a hotpluggable device, which may or may not
  have been used by a device;
* It may be a machine-type-provided property, which may or may not have
  been used by a device.
* It may be a user-provided property that was actually not used by
  any device.

Simplify the logic by having two separate fields: 'user_provided' and
'used'. This allows the entire global property validation logic to be
contained in a single function, and allows more specific error messages.

2177801a48 test-qdev-global-props: Run tests on subprocess
There are multiple reasons for running the global property tests on a
subprocess:

* We need the global_props lists to be empty for each test case, so
  global properties from the previous test won't affect the next one;
* We don't want the qdev_prop_check_global() warnings to pollute test
  output;
* With a subprocess, we can ensure qdev_prop_check_global() is printing
  the warning messages it should.

9d41401b90 tests: disable global props test for old glib
follow-up patch moves global property tests to subprocesses.
Unfortunately with old glib this causes:

tests/test-qdev-global-props.c: In function
‘test_static_prop’:
tests/test-qdev-global-props.c:80:5: error: implicit
declaration of function ‘g_test_trap_subprocess’
[-Werror=implicit-function-declaration]
tests/test-qdev-global-props.c:80:5: error: nested extern
declaration of ‘g_test_trap_subprocess’ [-Werror=nested-externs]

This function was only added in glib 2.38, and our
minimum version is 2.12.

To fix, disable the test for glib < 2.38.

Apply before that patch to avoid breaking bisect.

c2eb918e32 block: round up file size to nearest sector
Currently the file size requested by user is rounded down to nearest
sector, causing the actual file size could be a bit less than the size
user requested. Since some formats (like qcow2) record virtual disk
size in bytes, this can make the last few bytes cannot be accessed.

This patch fixes it by rounding up file size to nearest sector so that
the actual file size is no less than the requested file size.

Additionally, allow the user to specify when

blocks in use. This may be useful for identifying
problems in qtests that use more complicated
set-up and tear-down routines.

This functionality is used in my upcoming ahci-test v2

Replace "init/destroy" with "realize/unrealize" in SCSIDeviceClass,
which has errp as a parameter. So all the implementations now use
error_setg instead of error_report for reporting error.

Also in scsi_bus_legacy_handle_cmdline, report the error when
initializing the if=scsi devices, before returning it, because in the
callee, error_report is changed to error_setg. And the callers don't
have the right locations (e.g. "-drive if=scsi").

18a7d0c56e runner: Kill a program under test by time-out
If a program under test get frozen, the test should finish and report about its
failure.
In such cases the runner waits for 10 minutes until the program ends its
execution. After this time-out the program will be terminated and the test will
be marked as failed.

For current limitation of test image size to 10 MB as a maximum an execution of
each command takes about several seconds in general, so 10 minutes is enough to
discriminate freeze, but not drastically increase an overall test duration.

e.g. has L1/L2 tables but no refcount ones. Generation of an entirely

6d5e9372f6 image-fuzzer: Fuzzing functions for qcow2 images
The fuzz submodule of the qcow2 image generator contains fuzzing functions for
image fields.
Each fuzzing function contains a list of constraints and a call of a helper
function that randomly selects a fuzzed value satisfied to one of constraints.
For now constraints include only known as invalid or potentially dangerous
values. But after investigation of code coverage by fuzz tests they will be
expanded by heuristic values based on inner checks and flows of a program
under test.

Now fuzzing of a header, header extensions and a backing file name is
supported.

The purpose of the test runner is to prepare the test environment (e.g. create

parameters, indicate a test failure if the program was killed during the test
execution and collect core dumps, logs and other test artifacts.

The test runner doesn't depend on an image format, so it can be used with any
external image generator.

[Fixed path to qcow2 format module "qcow2" instead of "../qcow2" since
runner.py is no longer in a sub-directory.

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

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.

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.

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
feature, resulting in an error_set() assertion failure.

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

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.

87f68d3182 block: drop aio functions that operate on the main AioContext
The main AioContext should be accessed explicitly via qemu_get_aio_context().
Most of the time, using it is not the right thing to do.

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.

c6ea9b73b1 pc,vhost,virtio fixes, test
Bugfixes all over the place.
 
 There's a  non bugfix here: re-enabling the vhost-user test,
 though the patch just brings back functionality that
 I disabled earlier to fix mingw build failures.
 This is now sorted, and keeping the unit test enabled
 seems important since the feature relies on an external
 server to work, so isn't easy to test.
