2013-07-29spapr: Rename 'dprintf' to 'DPRINTF'Peter Maydell
'dprintf' is the name of a POSIX standard function so we should not be stealing it for our debug macro. Rename to 'DPRINTF' (in line with a number of other source files.)

2013-07-29spapr-vscsi: fix SOLNT bit in SRP_RSPAlexey Kardashevskiy
The driver calculates SOLNT bit from UCSOLNT and SCSOLNT bits from the request. The iu pointer has a type of srp_iu* which points to a union, so cmd and rsp overlap. As the vscsi_send_rsp function calls memset(iu, 0, sizeof(rsp)), it clears first 36 bytes of both cmd and rsp so cmd.sol_not is always zero at the moment of calculating rsp.sol_not. This fixes the bug. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Message-id: 1375073319-17488-1-git-send-email-aik@ozlabs.ru Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>

2013-07-29pseries: rework PAPR virtual SCSIAlexey Kardashevskiy
The patch reimplements handling of indirect requests in order to simplify upcoming live migration support. - all pointers (except SCSIRequest*) were replaces with integer indexes and offsets; - DMA'ed srp_direct_buf kept untouched (ie. BE format); - vscsi_fetch_desc() is added, now it is the only place where descriptors are fetched and byteswapped; - vscsi_req struct fields converted to migration-friendly types; - many dprintf()'s fixed. This also removed an unused field 'lun' from the spapr_vscsi device which is assigned, but never used. So, remove it.

2013-07-23hw: Avoid use of QOM type name macros in VMStateDescriptionsPeter Maydell
The name field in a VMStateDescription is part of the migration state versioning, so changing it will break migration. It's therefore a bad idea to use a QOM typename macro to initialize it, because in general we're free to rename QOM types as part of code refactoring and cleanup. For the handful of devices that were doing this by mistake, replace the QOM typenames with the corresponding literal strings.

2013-06-18scsi-disk: scsi-block device for scsi pass-through should not be removablePavel Hrdina
This patch adds a new SCSI_DISK_F_NO_REMOVABLE_DEVOPS feature.

2013-06-18scsi-generic: fix sign extension of READ CAPACITY(10) dataPaolo Bonzini
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 Hrdina
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 Gibson
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 Bellinger
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 ...
