2013-04-19vhost-scsi: new device supporting the tcm_vhost Linux kernel moduleNicholas Bellinger5-1/+378
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 The tgpt field of the SET_ENDPOINT ioctl is obsolete now, so it is not available from the QEMU command-line.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 ...

2013-04-19vhost: Add vhost_commit callback for SeaBIOS ROM region re-mappingNicholas Bellinger2-15/+41
This patch follows MST's recommendation to move checks for vhost_verify_ring_mappings() -> cpu_physical_memory_map() operations from MemoryListener->region_[add,del]() -> vhost_set_memory() into final MemoryListener->commit() -> vhost_commit() callback. It addresses the case where virtio-scsi vq ioport RAM re-mapping to read-only SeaBIOS ROM triggers a cpu_physical_memory_map() NIL MemoryRegionSection pointer failure. Also save vhost_dev->mem_changed_[start,end]_addr values in vhost_set_memory() for final ranges_overlap checks. (Thanks Paolo!) Cc: Michael S.

Configure to use the DTC submodule to build libfdt when no system libfdt is found. Prompt to install the DTC submodule if --enable-fdt is set but no DTC can be found. DTC has no out-of-tree build capability, so the configure will symlink the Makefile and scripts directory in the out of tree build directory and pass in all the needed DTC arguments to make out of tree build happen. Ideally we fix the DTC make to support out of tree, but did it this way to avoid commits to DTC.

This test compares all of the default register values against the spec. It turns out we deviate in quite a few places.
