From 116046127d1a3bad2853d02781ad9fee33f05e5a Mon Sep 17 00:00:00 2001 From: Mahesh Rajashekhara Date: Wed, 8 Feb 2012 22:51:04 -0800 Subject: [PATCH] [SCSI] aacraid: Added Sync.mode to support series 7/8/9 controllers Added Sync. mode to support Series 7/8/9 controller families: This is a compatibility mode for all these controller families. The Async. (Performance) mode can be changed in the future. First Async. mode version added for Series 7; Controller parameter aac_sync_mode added Signed-off-by: Mahesh Rajashekhara Signed-off-by: James Bottomley --- drivers/scsi/aacraid/aachba.c | 4 + drivers/scsi/aacraid/aacraid.h | 27 ++- drivers/scsi/aacraid/comminit.c | 21 ++- drivers/scsi/aacraid/commsup.c | 26 +++ drivers/scsi/aacraid/linit.c | 28 ++- drivers/scsi/aacraid/rx.c | 1 + drivers/scsi/aacraid/sa.c | 1 + drivers/scsi/aacraid/src.c | 293 ++++++++++++++++++++++++++------ 8 files changed, 338 insertions(+), 63 deletions(-) diff --git a/drivers/scsi/aacraid/aachba.c b/drivers/scsi/aacraid/aachba.c index 409f5805bdd6..52551662d107 100644 --- a/drivers/scsi/aacraid/aachba.c +++ b/drivers/scsi/aacraid/aachba.c @@ -151,7 +151,11 @@ int aac_msi; int aac_commit = -1; int startup_timeout = 180; int aif_timeout = 120; +int aac_sync_mode; /* Only Sync. transfer - disabled */ +module_param(aac_sync_mode, int, S_IRUGO|S_IWUSR); +MODULE_PARM_DESC(aac_sync_mode, "Force sync. transfer mode" + " 0=off, 1=on"); module_param(nondasd, int, S_IRUGO|S_IWUSR); MODULE_PARM_DESC(nondasd, "Control scanning of hba for nondasd devices."
