Jan, Default behavior for all 3 buses (FC, SPI, and SAS) with respect to MSI is OFF. It is up to user, whether they want to enable/disable MSI. Latest patch on that regard was to just set proper description value only. Thanks Kashyap -----Original Message----- From: linux-scsi-owner@xxxxxxxxxxxxxxx [mailto:linux-scsi-owner@xxxxxxxxxxxxxxx] On Behalf Of Jan Beulich Sent: Tuesday, March 10, 2009 4:27 PM To: James.Bottomley@xxxxxxxxxxxxxxxxxxxxx; yinghai@xxxxxxxxxx; Desai, Kashyap Cc: linux-scsi@xxxxxxxxxxxxxxx Subject: MSI override changes in mptbase The original patch splitting the single control up into separate ones for SPI, FC, and SAS seemed to have had the intention of doing just that, without altering defaults. Since it didn't do this correctly, a subsequent patch corrected the mistaken use of the perm macro argument, but didn't restore the default to on for the SAS case (instead it made the comment match the changed behavior). So the question is - was it indeed intended to change the default to off for the SAS case?
