[Qemu-devel] [PATCH 01/10] ahci: Don't allow creating slave drives

[Kevin Wolf]

An IDE bus provided by AHCI can only take a single IDE drive. If you add
a drive as slave, qemu used to accept the command line but the device
wouldn't be actually usable. Catch the situation instead and error out.

[Qemu-devel] [PATCH 03/10] ide: Reset BMIDEA bit when the bus master is stopped

[Kevin Wolf]

The device is supposed to reset the Bus Master IDE Active bit in the
status register when 0 is written to the Start/Stop Bus Master bit in
the command register.

In the common cases this happens automatically because bdrv_drain_all()
flushes the requests, but with a large PRDT it could remain set.

[Kevin Wolf]

This adds a simple IDE test case and starts by verifying that IDENTIFY

[Qemu-devel] [PATCH 07/10] qtest/ide-test: Test short and long PRDTs

[Kevin Wolf]

This tests the behaviour of the DMA engine when the given PRDT contains
physical region descriptors for either more or less bytes than the
IDE request is for.

[Qemu-devel] [PATCH 08/10] qemu-iotests: exclude vmdk for test 042

[Kevin Wolf]

From: Fam Zheng <famz@redhat.com>

Zero sized disk is not supported by qemu vmdk driver, exclude vmdk from
the test script.

As tested on vmware-vdiskmanager and vmware workstation, zero sized disk
is not supported by vmware, either.

[Qemu-devel] [PATCH 10/10] qemu-iotests: fix 017 018 for vmdk

[Kevin Wolf]

From: Fam Zheng <famz@redhat.com>

017 and 018 use /bin/mv to move base img from t.IMGFMG to t.IMGFMT.base
after filling data, this is not enough for vmdk, when t.IMGFMT is only a
description text file who points to t-{flat,s001,f001,...}.IMGFMT as
data extent, so testing such subformats alway fails on them.

This patch use the trick of temprorily changing TEST_IMG to avoid using
/bin/mv.
