Module Name: src
Committed By: pooka
Date: Tue Aug 24 11:23:35 UTC 2010
Modified Files:
src/sys/rump/dev: Makefile.rumpdev files.rump
Added Files:
src/sys/rump/dev/lib/libscsitest: Makefile SCSITEST.ioconf component.c
scsitest.c shlib_version
Log Message:
Implement enough of a SCSI target to be able to perform tests on
our SCSIPI driver stack. Currently we pretend to be a single CD
controller with an optional host file as the image, but I guess
the sky's the limit.
