2013-06-20dma: eliminate DMAContextPaolo Bonzini3-4/+4
The DMAContext is a simple pointer to an AddressSpace that is now always already available. Make everyone hold the address space directly, and clean up the DMA API to use the AddressSpace directly.

2013-06-18vhost-scsi: fix k->set_guest_notifiers() NULL dereferenceStefan Hajnoczi1-1/+1
Coverity picked up a copy-paste bug. In vhost_scsi_start() we check for !k->set_guest_notifiers and error out. The check probably got copied but instead of erroring we actually use the function pointer!

2013-06-18scsi-disk: scsi-block device for scsi pass-through should not be removablePavel Hrdina1-3/+11
This patch adds a new SCSI_DISK_F_NO_REMOVABLE_DEVOPS feature. By this feature we can set that the scsi-block (scsi pass-through) device will still be removable from the guest side, but from monitor it cannot be removed.

2013-06-18scsi-generic: check the return value of bdrv_aio_ioctl in execute_commandPavel Hrdina1-0/+3
This fixes the bug introduced by this commit ad54ae80c73f. The bdrv_aio_ioctl() still could return null and we should return an error in that case. Cc: qemu-stable@nongnu.org Signed-off-by: Pavel Hrdina <phrdina@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2013-06-18scsi-generic: fix sign extension of READ CAPACITY(10) dataPaolo Bonzini1-2/+3
Issuing the READ CAPACITY(10) command in the guest will cause QEMU to update its knowledge of the maximum accessible LBA in the disk. The recorded maximum LBA will be wrong if the disk is bigger than 1TB, because ldl_be_p returns a signed int. When this is fixed, a latent bug will be unmasked. If the READ CAPACITY(10) command reported an overflow (0xFFFFFFFF), we must not overwrite the previously-known maximum accessible LBA, or the guest will fail to access the disk above the first 2TB.

2013-06-18scsi: reset cdrom tray statuses on scsi_disk_resetPavel Hrdina1-0/+3
Tray statuses should be also reset. Some guests may lock the tray and right after resetting the guest it should be unlocked and closed. This is done on power-on, reset and resume from suspend/hibernate on bare-metal. This fix is already committed for IDE CD. Check the commit a7f3d65b65b8c86a5ff0c0abcfefb45e2ec6fe4c. Test results on bare-metal: - on reset/power-on the CD-ROM tray is closed even before the monitor is turned on - on resume from suspend/hibernate the tray is also closed before the monitor is turned on From test results it seems that this behavior is OS and probably BIOS independent.

2013-04-26pseries: Convert VIO code to QOM style type safe(ish) castsDavid Gibson1-6/+9
Curerntly the pseries VIO device code contains quite a few explicit uses of DO_UPCAST and plain C casts. This is (obviously) type unsafe, and not the conventional way of doing things in the QOM model. This patch converts the code to use the QOM convention of per-type macros to do verified casts with OBJECT_CHECK().

2013-04-19vhost-scsi: new device supporting the tcm_vhost Linux kernel moduleNicholas Bellinger2-1/+293
The WWPN specified in configfs is passed to "-device vhost-scsi-pci". The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line. Instead, I hardcode it to zero. Changes in Patch-v2: - Add vhost_scsi_get_features() in order to determine feature bits supports by host kernel (mst + nab) - Re-enable usage of DEFINE_VIRTIO_COMMON_FEATURES, and allow EVENT_IDX to be disabled by host in vhost_scsi_get_features() - Drop unused hotplug bit in DEFINE_VHOST_SCSI_PROPERTIES Changes in Patch-v1: - Set event_idx=off by default (nab, thanks asias) - Disable hotplug feature bit for v3.9 tcm_vhost kernel code, need to re-enable in v3.10 (nab) - Update to latest qemu.git/master HEAD Changes in WIP-V3: - Drop ioeventfd vhost_scsi_properties (asias, thanks stefanha) - Add CONFIG_VHOST_SCSI (asias, thanks stefanha) - Add hotplug feature bit Changes in WIP-V2: - Add backend guest masking support (nab) - Bump ABI_VERSION to 1 (nab) - Set up set_guest_notifiers (asias) - Set up vs->dev.vq_index (asias) - Drop vs->vs.vdev.{set,clear}_vhost_endpoint (asias) - Drop VIRTIO_CONFIG_S_DRIVER check in vhost_scsi_set_status (asias) Howto: Use the latest seabios, at least commit b44a7be17b git clone git://git.seabios.org/seabios.git make cp out/bios.bin /usr/share/qemu/bios.bin qemu -device vhost-scsi-pci,wwpn=naa.6001405bd4e8476d,event_idx=off ...
