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.
Why is that change in behavior for SAS needed then?
Thanks, Jan
Jan,
Best approach is to enable/disable MSI Interrupt on the fly. We are not supporting that feature currently. Something like setting DMA mask through probe code, we should enable/disable MSI interrupt through init code. Eventually, If MSI enable/disable is not on the fly, it will be always better to keep in default disable in module para of driver.
