This is my QEMU Google Summer of Code project.
Here I introduce new device - ATAPI-SCSI bridge.
Its purpose is to unify IDE ATAPI CD-ROM emulation
with SCSI CD-ROM emulation to reduce code duplication and squash bugs.
It's purpose is simple - it just forwards ATAPI commands
to SCSI side for parsing and execution.
Example of using:
qemu-system-x86_64 \
-drive if=none,file=<filename>,id=cdrom \
-drive if=none,id=fake \
-device ide-bridge,id=bridge,drive=fake \
-device scsi-cd,drive=cdrom,bus=bridge.0 \
-hda diskimage \
-m 1024
Alexander Bezzubikov (5):
ide: ATAPI-SCSI bridge TypeInfo and init function created
ide: necessary checks corrected to treat ATAPI-SCSI bridge as CDROM
ATAPI-SCSI bridge functions created an can be used by bridge
scsi: SCSIDiskReq declaration moved to header
ide: ATAPI-SCSI bridge transfer is treated as PIO
