Hi,
Doesn't fly. Either every SCSI HBA uses QEMUSG64List (thus making this
aequivalent to the next option from the scsi point of view), or
scsi-disk would have to support both formats.
A device or device set which is always 64-bit would always use
QEMUSG64List. A device which is always 32-bit would use QEMUSG32List.
A scsi-disk can be connected to both 32-bit and 64-bit HBAs though ...
Question is how big the performance hit actually is and whenever we
are willing to accept that or not ...
Probably unmeasurable, but the qemu-devel thread size will be very
measurable so not worth it.
;)
cheers,
Gerd
