[Qemu-devel] [patch] esp.c fast SCSI-bus reset

[Artyom Tarasenko]

It seems to make a little sense to raise an interrupt still having
"bus reset" status, since it makes the host think the bus is busy.
The proper way would be to tell all the scsi devices to reset before
the interrupt.
The patch makes scsi probe to come a little further when using OBP
under sparc32.
