From bc73905abf7701920fe687564ecd3c6b316b9a2e Mon Sep 17 00:00:00 2001 From: James Smart Date: Wed, 4 Aug 2010 16:11:18 -0400 Subject: [PATCH] [SCSI] lpfc 8.3.16: SLI Additions, updates, and code cleanup - Remove unneeded Endian swap for Block Guard IOCB response - Add a check for mailbox active before issuing the heartbeat command - Correct heartbeat last_completion updates to avoid unneeded heartbeats - Add Security crypto support to CONFIG_PORT mailbox command - Add fips level and fips spec revision sysfs parameters - Remove duplicate setting of ext_byte_len fields in lpfc_bsg_issue_mbox - Switch call to memcpy_toio to __write32_copy to prevent unaligned 64 bit copy - Change log message 0318 from an error to a warning as it is not an error - Patch an incorrect call to lpfc_drain_txq on SLI-3 functions Signed-off-by: Alex Iannicelli Signed-off-by: James Smart Signed-off-by: James Bottomley --- drivers/scsi/lpfc/lpfc.h | 3 +++ drivers/scsi/lpfc/lpfc_attr.c | 46 +++++++++++++++++++++++++++++++++- drivers/scsi/lpfc/lpfc_bsg.c | 9 ------- drivers/scsi/lpfc/lpfc_compat.h | 3 +-- drivers/scsi/lpfc/lpfc_hbadisc.c | 2 +- drivers/scsi/lpfc/lpfc_hw.h | 26 +++++++++++--------- drivers/scsi/lpfc/lpfc_init.c | 53 +++++++++++++++++++++++++++------------- drivers/scsi/lpfc/lpfc_scsi.c | 8 +++--- drivers/scsi/lpfc/lpfc_sli.c | 29 +++++++++++++++++----- 9 files changed, 128 insertions(+), 51 deletions(-) diff --git a/drivers/scsi/lpfc/lpfc.h b/drivers/scsi/lpfc/lpfc.h index 3482d5a..a50aa03 100644 --- a/drivers/scsi/lpfc/lpfc.h +++ b/drivers/scsi/lpfc/lpfc.h @@ -775,6 +775,7 @@ struct lpfc_hba { uint8_t temp_sensor_support;
