* scsi: qla2xxx: Simplify the functions for dumping firmwareBart Van Assche2020-05-191-10/+11
| | | | | | | | | | | | | | | | | | | | | | | | | Instead of passing an argument to the firmware dumping functions that tells these functions whether or not to obtain the hardware lock, obtain that lock before calling these functions.

* scsi: qla2xxx: Fix MPI failure AEN (8200) handlingArun Easi2020-04-241-0/+3
| | | | | | | | | | | | | | | | | | | | | | | Today, upon an MPI failure AEN, on top of collecting an MPI dump, a regular firmware dump is also taken and then chip reset. This is disruptive to IOs and not required. 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) Link: https://lore.kernel.org/r/20200331104015.24868-2-njavali@marvell.com Reported-by: kbuild test robot <lkp@intel.com> Reviewed-by: Himanshu Madhani <himanshu.madhani@oracle.com> Signed-off-by: Arun Easi <aeasi@marvell.com> Signed-off-by: Nilesh Javali <njavali@marvell.com> Signed-off-by: Martin K.

* scsi: qla2xxx: Update BPM enablement semantics.Andrew Vasquez2020-02-281-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | commit e4e3a2ce9556 ("scsi: qla2xxx: Add ability to autodetect SFP type") takes a heavy handed approach to BPM (Buffer Plus Management) enablement: 1) During hardware initialization, if an LR-capable transceiver is recognized, the driver schedules a disruptive post-initialization chip-reset (ISP-ABORT) to allow the BPM settings to be sent to the firmware. This chip-reset will result in (short-term) path-loss to all fc-rports and their attached SCSI devices. 2) LR-detection is triggered during any link-up event, resulting in a refresh and potential chip-reset Based on firmware-team guidance, upon LR-capable transceiver recognition, the driver's hardware initialization code will now re-execute firmware with the new BPM settings, then continue on with driver initialization. To address the second issue, the driver performs LR-capable detection upon the driver receiving a transceiver-insertion asynchronous event from firmware. No short-term path loss is needed with this new semantic.

| | | | | | | | | | | When SGE buffer containing DIF information crosses 4G boundary, it results in DMA error. This patch fixes this issue by calculating SGE buffer size and if it crosses 4G boundary, driver will split it into multiple SGE buffers to avoid DMA error.

* scsi: qla2xxx: Add mode control for each physical portQuinn Tran2018-09-111-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add ability to allow each physical port to control operating mode. Current code forces all ports to behave in one mode (i.e. initiator, target or dual). This patch allows user to select the operating mode for each port. - Driver must be loaded in dual mode to allow resource allocation modprobe qla2xxx qlini_mode=dual - In addition user can make adjustment to exchange resources using following command echo 1024 > /sys/class/scsi_host/host<x>/ql2xiniexchg echo 1024 > /sys/class/scsi_host/host<x>/ql2xexchoffld - trigger mode change and new setting of ql2xexchoffld|ql2xiniexchg echo [<value>] > /sys/class/scsi_host/host<x>/qlini_mode where, value can be one of following - enabled - disabled - dual - exclusive Signed-off-by: Quinn Tran <quinn.tran@cavium.com> Signed-off-by: Himanshu Madhani <himanshu.madhani@cavium.com> Signed-off-by: Martin K.

| | | | | | | | | | | | | | Using GPNFT/GNNFT command will be able to cover switch database with less number of scans. This patch removes Get NportID with provided WWPN/GIDPN switch command. By making this change, in large fabric with lots of remote port or NPIV ports with noisy SAN, the number of GIDPN commands issued by a port when it detects large number of remote ports going away or coming back, can overwhelmn the switch and it can becomde unresponsive. In a case where the fabric has not change, GIDPN is not required.

* scsi: qla2xxx: Move rport registration out of internal work_listQuinn Tran2018-09-111-2/+3
| | | | | | | | | | | | | | | | | | Currently, the rport registration is being called from a single work element that is used to process QLA internal "work_list". This work_list is meant for quick and simple task (ie no sleep). The Rport registration process sometime can be delayed by upper layer. This causes back pressure with the internal queue where other jobs are unable to move forward. This patch will schedule the registration process with a new work element (fc_port.reg_work). While the RPort is being registered, the current state of the fcport will not move forward until the registration is done. If the state of the fabric has changed, a new field/next_disc_state will record the next action on whether to 'DELETE' or 'Reverify the session/ADISC'.

The biggest observable change is going to be that we're (again) trying to switch to mulitqueue as the default (a user can still override the setting on the kernel command line).
