4f6a57c23b scsi: qla2xxx: Remove in_interrupt() from qla83xx-specific code
qla83xx_wait_logic() is used to control the frequency of device IDC lock
retries. If in_interrupt() is true, it does 20 loops of cpu_relax().
Otherwise, it sleeps for 100ms and yields the CPU.

While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: that qla83xx_wait_logic() is exclusively
called by qla83xx_idc_lock() / unlock(), and they always run from process
context. Below is an analysis of all the idc lock/unlock callers, in order
of appearance:

  - qla_os.c:
      qla83xx_nic_core_unrecoverable_work(),
      qla83xx_idc_state_handler_work(),
      qla83xx_nic_core_reset_work(),
      qla83xx_service_idc_aen(), all workqueue context

  - qla_os.c: qla83xx_check_nic_core_fw_alive(), has msleep()

  - qla_os.c: qla83xx_set_drv_presence(), called once from
    qla2x00_abort_isp(), which is bound to process-context ->abort_isp()
    hook. It also invokes wait_for_completion_timeout() through the chain
    qla2x00_configure_hba() => qla24xx_link_initialize() =>
    qla2x00_mailbox_command().

  - qla_os.c: qla83xx_clear_drv_presence(), which is called from
    qla2x00_abort_isp() discussed above, and from qla2x00_remove_one()
    which is PCI process-context ->remove() hook.

  - qla_os.c: qla83xx_need_reset_handler(), has a one second msleep() in
    a loop.

  - qla_os.c: qla83xx_device_bootstrap(), called only by
    qla83xx_idc_state_handler(), which has multiple msleep()
    invocations.

  - qla_os.c: qla83xx_idc_state_handler(), multiple msleep()
    invocations.

  - qla_attr.c: qla2x00_sysfs_write_reset(), sysfs bin_attribute
    ->write() hook, process context

  - qla_init.c: qla83xx_nic_core_fw_load()
      => qla_init.c: qla2x00_initialize_adapter()
        => bound to isp_operations ->initialize_adapter() hook
        ** => qla_os.c: qla2x00_probe_one(), PCI ->probe() process ctx

  - qla_init.c: qla83xx_initiating_reset(), msleep() in a loop.

  - qla_init.c: qla83xx_nic_core_reset(), called by
    qla83xx_nic_core_reset_work(), workqueue context.

Remove the in_interrupt() check, and thus replace the entirety of
qla83xx_wait_logic() with an msleep(QLA83XX_WAIT_LOGIC_MS).

Mark qla83xx_idc_lock() / unlock() with "Context: task, can sleep".

Driver was using a shorter timeout waiting for PLOGI from the peer in
point-to-point configurations. Some devices takes some time (~4 seconds) to
initiate the PLOGI. This peer initiating PLOGI is when the peer has a
higher P-WWN.

Increase the wait time based on N2N R_A_TOV.

8d1f1ffaeb scsi: qla2xxx: Remove pci-dma-compat wrapper API
The legacy API wrappers in include/linux/pci-dma-compat.h should go away as
they create unnecessary midlayering for include/linux/dma-mapping.h API.
Instead use dma-mapping.h API directly.

The patch has been generated with the coccinelle script below.  Compile
tested.

FCP T10-PI and NVMe features are independent of each other. This patch
allows both features to co-exist.

This reverts commit 5da05a26b8305a625bc9d537671b981795b46dab.

cast explicitly to uint16_t and uint32_t. Additionally, remove superfluous
void * casts.

The issue happens because no real ISP reset is executed.  The

vha->flags.online will be not zero for ISP reset procedure.  This patch
sets vha->flags.online to 1 before calling ->abort_isp() for starting the
ISP reset.

cbb01c2f2f scsi: qla2xxx: Fix MPI failure AEN (8200) handling
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)

5a263892d7 scsi: qla2xxx: check UNLOADING before posting async work
qlt_free_session_done() tries to post async PRLO / LOGO, and waits for the
completion of these async commands. If UNLOADING is set, this is doomed to
timeout, because the async logout command will never complete.

The only way to avoid waiting pointlessly is to fail posting these commands
in the first place if the driver is in UNLOADING state.  In general,
posting any command should be avoided when the driver is UNLOADING.

With this patch, "rmmod qla2xxx" completes without noticeable delay.

856e152a3c scsi: qla2xxx: set UNLOADING before waiting for session deletion
The purpose of the UNLOADING flag is to avoid port login procedures to
continue when a controller is in the process of shutting down.  It makes
sense to set this flag before starting session teardown.

Furthermore, use atomic test_and_set_bit() to avoid the shutdown being run
multiple times in parallel. In qla2x00_disable_board_on_pci_error(), the
test for UNLOADING is postponed until after the check for an already
disabled PCI board.

b0f18eee6f scsi: qla2xxx: Update BPM enablement semantics.
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.

c81ef0ed44 scsi: qla2xxx: Simplify the code for aborting SCSI commands
Since the SCSI core does not reuse the tag of the SCSI command that is
being aborted by .eh_abort() before .eh_abort() has finished it is not
necessary to check from inside that callback whether or not the SCSI
command has already completed. Instead, rely on the firmware to return an
error code when attempting to abort a command that has already
completed. Additionally, rely on the firmware to return an error code when
attempting to abort an already aborted command.

In qla2x00_abort_srb(), use blk_mq_request_started() instead of
sp->completed and sp->aborted.
