From: Moore, Eric Date: Fri, 13 Jan 2006 23:25:29 +0000 (-0700) Subject: [SCSI] fusion - fix pci express bug X-Git-Tag: firefly_0821_release~38898^2~25 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=569b11dcfa9d764e775f9e964a680c32265ab7f2;p=firefly-linux-kernel-4.4.55.git [SCSI] fusion - fix pci express bug The fix is to write 'MPI_HIM_DIM' to the Host Interrupt Mask register, when enabling interrupts. Instead of the tilde of MPI_HIM_RIM. Apparently writing '1's to some of the reserved bits was causing all the bits to go to `1`, which effectly disabled all interrupts.
