This is disruptive to IOs and not required. So, make the firmware dump collection, followed by chip reset optional (not done by default). Firmware dump buffer and MPI dump buffer are independent of each other with this change and each can have dump that was taken at two different times for two different issues. The MPI dump is saved in a separate buffer and is retrieved differently from firmware dump. To collect full dump on MPI failure AEN, a module parameter is introduced: ql2xfulldump_on_mpifail (default: 0) Signed-off-by: Arun Easi Signed-off-by: Nilesh Javali Reported-by: kbuild test robot Reviewed-by: Himanshu Madhani --- drivers/scsi/qla2xxx/qla_attr.c | 30 +++++++- drivers/scsi/qla2xxx/qla_def.h | 13 +++- drivers/scsi/qla2xxx/qla_gbl.h | 3 + drivers/scsi/qla2xxx/qla_init.c | 2 + drivers/scsi/qla2xxx/qla_isr.c | 54 +++++++++----- drivers/scsi/qla2xxx/qla_os.c | 6 ++ drivers/scsi/qla2xxx/qla_tmpl.c | 121 ++++++++++++++++++++++++++------ 7 files changed, 186 insertions(+), 43 deletions(-) diff --git a/drivers/scsi/qla2xxx/qla_attr.c b/drivers/scsi/qla2xxx/qla_attr.c index 97cabd7e0014..3a5f6f27587e 100644 --- a/drivers/scsi/qla2xxx/qla_attr.c +++ b/drivers/scsi/qla2xxx/qla_attr.c @@ -26,7 +26,8 @@ qla2x00_sysfs_read_fw_dump(struct file *filp, struct kobject *kobj, struct qla_hw_data *ha = vha->hw;

This leads to hang in nvme_fc layer in nvme_fc_delete_association() which waits for all I/Os to be returned, which is seen as hang in the application.
