2010-05-19Revert "monitor: Convert do_pci_device_hot_remove() to QObject"Markus Armbruster1-3/+2
We don't want pci_del in QMP. Use device_del instead. This reverts commit 6848d827162fea039f2658414a4adb6164a4f9b0. Conflicts: hw/pci-hotplug.c sysemu.h Signed-off-by: Markus Armbruster <armbru@redhat.com>
2010-05-19Revert "PCI: Convert pci_device_hot_add() to QObject"Markus Armbruster1-41/+5
Short story: We don't want pci_add in QMP. Long story follows. pci_add can do two things: * Hot plug a PCI NIC. device_add is more general. * Hot plug a PCI disk controller, and a drive connected to it. The controller is either virtio-blk-pci (if=virtio) or lsi53c895a (if=scsi). With the latter, the drive is optional. Use drive_add to hotplug additional SCSI drives. Except drive_add is not available in QMP. device_add is more general for controllers and the guest part of drives. I'm working on a more general alternative for the host part of drives. Why am I proposing to remove pci_add from QMP before its replacement is ready? I want it out sooner rather than later, because it isn't fully functional (errors and drive_add are missing), and we do not plan to complete the job. In other words, it's not really usable over QMP now, and it's not what we want for QMP anyway. Since we don't want it to be used over QMP, we should take it out, not leave it around as a trap for the uninitiated. Dan Berrange confirmed that libvirt has no need for pci_add & friends over QMP.

2010-05-18target-s390: add firmware codeAlexander Graf1-0/+26
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 Wolf1-4/+4
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>

2010-05-15vmstate: Add support for alias IDJan Kiszka3-2/+22
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 KAWASAKI1-3/+169
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.
