From c0c1151276aae83dffbe3f2837a3b1d893894115 Mon Sep 17 00:00:00 2001 From: James Smart Date: Tue, 24 May 2011 11:41:34 -0400 Subject: [PATCH] [SCSI] lpfc 8.3.24: Extended hardware support and support dump images Extended hardware support and support dump images: - Make the size to be MAILBOX_SYSFS_MAX (4096) so that it allows the maximum sysfs binary access interface possible. - Add ids and model names for new hardware - Add capability of inducing SLI4 firmware dump obj file Signed-off-by: Alex Iannicelli Signed-off-by: James Smart Signed-off-by: James Bottomley --- drivers/scsi/lpfc/lpfc_attr.c | 64 ++++++++++++++++++++++++++++++++++- drivers/scsi/lpfc/lpfc_hw.h | 4 ++- drivers/scsi/lpfc/lpfc_hw4.h | 19 +++++++++++ drivers/scsi/lpfc/lpfc_init.c | 18 +++++++--- 4 files changed, 98 insertions(+), 7 deletions(-) diff --git a/drivers/scsi/lpfc/lpfc_attr.c b/drivers/scsi/lpfc/lpfc_attr.c index 8dcbf8fff673..44816be4d724 100644 --- a/drivers/scsi/lpfc/lpfc_attr.c +++ b/drivers/scsi/lpfc/lpfc_attr.c @@ -754,6 +754,61 @@ lpfc_issue_reset(struct device *dev, struct device_attribute *attr, return status;
