qla82xx_idc_lock() spins on a certain hardware state until it's updated. At
the end of each spin, if in_interrupt() is true, it does 20 loops of
cpu_relax(). Otherwise, it yields the CPU.
While in_interrupt() is ill-defined and does not provide what the name
suggests, it is not needed here: qla82xx_idc_lock() is always called from
process context. Below is an analysis of its callers, in order of
appearance:
- qla_nx.c: qla82xx_device_bootstrap(), only called by
qla82xx_device_state_handler(), has multiple msleep()s.
- qla_nx.c: qla82xx_need_qsnt_handler(), has one second msleep()
- qla_nx.c: qla82xx_wait_for_state_change(), one second msleep()
- qla_nx.c: qla82xx_need_reset_handler(), can sleep up to 10 seconds
- qla_nx.c: qla82xx_device_state_handler(), has multiple msleep()s
- qla_nx.c: qla82xx_abort_isp(), if it's a qla82xx controller, calls
qla82xx_device_state_handler(), which sleeps. It's also bound to
isp_operations ->abort_isp() hook, where all the callers are in process
context.
- qla_nx.c: qla82xx_beacon_on(), bound to isp_operations ->beacon_on()
hook. That hook is only called once, in a mutex locked context, from
qla2x00_beacon_store().
- qla_nx.c: qla82xx_beacon_off(), bound to isp_operations ->beacon_off()
hook. Like ->beacon_on(), it's only called once, in a mutex locked
context, from qla2x00_beacon_store().
- qla_nx.c: qla82xx_fw_dump(), calls qla2x00_wait_for_chip_reset(), which
has msleep() in a loop. It is bound to isp_operations ->fw_dump()
hook. That hook *is* called from atomic context at qla_isr.c by
multiple interrupt handlers. Nonetheless, it's other controllers
interrupt handlers, and not the qla82xx.
- qla82xx_msix_default() and qla82xx_msix_rsp_q() call
qla24xx_process_response_queue() which doesn't implement the firmware
dumping.
- qla_attr.c: qla2x00_sysfs_write_fw_dump(), and
qla2x00_sysfs_write_reset(), process-context sysfs ->write() hooks.
- qla_os.c: qla2x00_probe_one(). PCI ->probe(), process context.
- qla_os.c: qla2x00_clear_drv_active(), called solely from
qla2x00_remove_one(), which is PCI ->remove() hook, process context.
- qla_os.c: qla2x00_do_dpc(), kthread function, process context.
Remove the in_interrupt() check. Change qla82xx_idc_lock() specification to
a purely process-context function. Mark it with "Context: task, might
sleep".
Change qla82xx_idc_lock() implementation to sleep 100ms, instead of a
schedule(), for each spin. This is more deterministic, and it matches the
other qla models idc_lock() functions.

qla4_82xx_crb_win_lock() spins on a certain hardware state until it's
updated. At the end of each spin, if in_interrupt() is true, it does 20
loops of cpu_relax(). Otherwise, it yields the CPU.
The in_interrupt() macro is ill-defined as it does not provide what the
name suggests, and it does not catch the intended use-case here.
qla4_82xx_crb_win_lock() is always invoked with scsi_qla_host::hw_lock
acquired, with disabled interrupts. If the caller is in process context, as
in qla4_82xx_need_reset_handler(), then in_interrupt() will return false
even though it is not allowed to call schedule().
Remove the in_interrupt() check.
Change qla4_82xx_crb_win_lock() specification to a purely atomic
function. Mark it as static, remove its forward declaration, and move it
above its callers. To avoid hammering the PCI bus while spinning, use a 10
micro-second delay instead of cpu_relax().

hisi_sas_task_exec() uses preemptible() to see if it's safe to block. This
does not work for CONFIG_PREEMPT_COUNT=n kernels in which preemptible()
always returns 0.
The problem is masked when enabling some of the common Kconfig.debug
options (like CONFIG_DEBUG_ATOMIC_SLEEP), as they implicitly enable the
preemption counter.
In general, driver leaf functions should not make logic decisions based on
the context they're called from. The caller should be the entity
responsible for explicitly indicating context.
Since hisi_sas_task_exec() already has a gfp_t flags parameter, use it as
the explicit context marker.

Drivers should do only device-specific jobs. But in general, drivers using
legacy PCI PM framework for .suspend()/.resume() have to manage many PCI
PM-related tasks themselves which can be done by PCI Core itself. This
brings extra load on the driver and it directly calls PCI helper functions
to handle them.
Switch to the new generic framework by updating function signatures and

Every PM8001_<FOO>_DBG macro uses an internal call to pm8001_printk.
Convert all uses of:
PM8001_<FOO>_DBG(hba, pm8001_printk(fmt, ...))
to
pm8001_dbg(hba, <FOO>, fmt, ...)
so the visual complexity of each macro is reduced.
The repetitive macro definitions are converted to a single pm8001_dbg and
the level is concatenated using PM8001_##level##_LOGGING for the specific
level test.
Done with coccinelle, checkpatch and a little typing of the new macro
definition.
Miscellanea:
- Coalesce formats
- Realign arguments
- Add missing terminating newlines to formats
- Remove trailing spaces from formats
