This setting does not need to be conditional on Atari ST or TT. Signed-off-by: Finn Thain Tested-by: Michael Schmitz --- Changed since v1: - Set the default cmd_per_lun to 4 based on test results. Changed since v2: - Revert the default cmd_per_lun to 2, like in the v1 patch, because a uniform default across all ten 5380 wrapper drivers is worth more than a tiny improvement in one particular microbenchmark on one system. Michael tells me that 2 is also the best setting for his Atari Falcon. --- drivers/scsi/atari_scsi.c | 3 +-- 1 file changed, 1 insertion(+), 2 deletions(-) Index: linux/drivers/scsi/atari_scsi.c =================================================================== --- linux.orig/drivers/scsi/atari_scsi.c 2016-03-21 13:31:33.000000000 +1100 +++ linux/drivers/scsi/atari_scsi.c 2016-03-21 13:31:43.000000000 +1100 @@ -752,6 +752,7 @@ static struct scsi_host_template atari_s .eh_abort_handler = atari_scsi_abort, .eh_bus_reset_handler = atari_scsi_bus_reset, .this_id = 7, + .cmd_per_lun = 2, .use_clustering = DISABLE_CLUSTERING, .cmd_size = NCR5380_CMD_SIZE, }; @@ -788,11 +789,9 @@ static int __init atari_scsi_probe(struc */ if (ATARIHW_PRESENT(TT_SCSI)) { atari_scsi_template.can_queue = 16; - atari_scsi_template.cmd_per_lun = 8; atari_scsi_template.sg_tablesize = SG_ALL; } else { atari_scsi_template.can_queue = 8; - atari_scsi_template.cmd_per_lun = 1; atari_scsi_template.sg_tablesize = SG_NONE; }
