Re: [Qemu-devel] [PATCH 0/4] megaraid_sas HBA emulation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



  Hi,

The device can be accessed by

-drive if=raid,file=XXX

Don't extend that qemu automagic please.  The new way to handle this is:

  -drive if=none,id=mydisk,file=/path/to/some/disk.img
  -device megasas,id=raid
  -device scsi-disk,bus=raid.0,scsi-id=1,drive=mydisk

In order to support SCSI command emulation I had to update /
patch up the existing SCSI disk support. This might be
not to everyones taste, so I'm open to alternative
suggestions.

But I certainly do _not_ want to update the SCSI disk
emulation, as this is really quite tied to the SCSI parallel
interface used by the old lsi53c895a.c.

--verbose please. I'd prefer to fix scsi-disk bugs and/or limitations instead of working around them.

Plus it doesn't do scatter-gather list handling,

Which should be fixed anyway.

cheers,
  Gerd
