2010-05-18target-s390: add firmware codeAlexander Graf
This patch adds a firmware blob to the S390 target. The blob is a simple implementation of a virtio client that tries to read the second stage bootloader from sectors described as of offset 0x20 in the MBR. In combination with an updated zipl this allows for booting from virtio block devices. This firmware is built from the same sources as the second stage bootloader. You can find a virtio capable s390-tools in this repo: git://repo.or.cz/s390-tools.git Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Aurelien Jarno <aurelien@aurel32.net>

2010-05-17ide: Fix ide_dma_cancelKevin Wolf
When cancelling a request, bdrv_aio_cancel may decide that it waits for completion of a request rather than for cancellation. IDE therefore can't abandon its DMA status before calling bdrv_aio_cancel; otherwise the callback of a completed request would use invalid data. Signed-off-by: Kevin Wolf <kwolf@redhat.com>

2010-05-15serial: Register vmstate via qdevJan Kiszka

2010-05-15vmstate: Add support for alias IDJan Kiszka
Some legacy users (mostly PC devices) of vmstate_register manage instance IDs on their own, and that unfortunately in a way that is incompatible with automatically generated ones. This so far prevents switching those users to vmstates that are registered by qdev. To establish a migration path, this patch introduces the concept of alias IDs. They can be passed to an extended vmstate registration service, and qdev provides a set service to be used during device init. find_se will consider the alias in addition to the default ID. We can then start generating the default ID automatically and writing it on vmsave, thus converting that format without breaking support for upward migration. The user is required specify the highest vmstate version for which the alias is required. Once this version falls behind the minimum required for a specific vmstate, an assertion triggers to motivate cleaning up the obsolete alias.

2010-05-15sh: sm501: add 2D engine supportShin-ichiro KAWASAKI
In linux kernel v2.6.33, sm501 frame buffer driver modified to support 2D graphics engine on sm501 chip. One example is "fill rectangle" operation. But current qemu's sm501 emulation doesn't support it. This results in graphics console disturbance. This patch introduces sm501 2D graphics engine emulation and solve this problem. Add SM501 2D hardware engine support. - Add 2D engine register set read/write handlers. - Support 'fill rectangle'. Other operations are left for future work. - Update SM501 support status comment.

2010-05-12pci: irq_state vmstate breakageMichael S. Tsirkin
Code for saving irq_state got vm_state macros wrong, passing in the wrong parameter. As a result, we both saved a wrong value and restored it to a wrong offset. This leads to device and bus irq counts getting out of sync, which in turn leads to interrupts getting lost or never cleared, such as https://bugzilla.redhat.com/show_bug.cgi?id=588133 Signed-off-by: Michael S.

2010-05-12pci: cleanly backout of pci_qdev_init()Alex Williamson
If the init function of a device fails, as might happen with device assignment, we never undo the work done by do_pci_register_device().
