[Qemu-devel] [PULL 01/10] fdc: remove sparc sun4m mutations

[John Snow]

From: Hervé Poussineau <hpoussin@reactos.org>

They were introduced in 6f7e9aec5eb5bdfa57a9e458e391b785c283a007 and
82407d1a4035e5bfefb53ffdcb270872f813b34c and lots of bug fixes were done after that.

This fixes (at least) the detection of the floppy controller on Debian 4.0r9/SPARC,
and SS-5's OBP initialization routine still works.

[Qemu-devel] [PULL 02/10] qtest/ahci: add qcow2 support to ahci-test

[John Snow]

This will enable the testing of high offsets without
wasting a lot of disk space, and does not impact the
previous tests.

mkimg and mkqcow2 are added to libqos for other tests.

[Qemu-devel] [PULL 07/10] libqtest: add qmp_async

[John Snow]

Add qmp_async, which lets us send QMP commands asynchronously.
This is useful when we want to send commands that will trigger
event responses, but we don't know in what order to expect them.

Sometimes the event responses may arrive even before the command
confirmation will show up, so it is convenient to leave the responses
in the stream.

I've just discovered that this change means that "make check"
will fail on a system which doesn't have an installed qemu-img
and where the build was configured with --disable-tools, and
with a confusing error message:

Failed to execute child process "(null)" (No such file or directory)
**
ERROR:/Users/pm215/src/qemu/tests/libqos/libqos.c:171:void mkimg(const
char *, const char *, unsigned int): assertion failed: (ret && !err)

The test should probably be skipped if qemu-img isn't available.

thanks

In part I feel that it's reasonable to expect that you have tools
available in order to run tests, but I don't want to be the first to
break rank.

(At the very least, the error is extremely confusing.)

I'm writing a patch now to skip the LBA48 high-sector tests if qemu-img
isn't available and fall back to raw.
