PM/devfreq: Do not switch governors from sysfs when device is suspended
There is a possibility to switch the governors from sysfs even when the
device is in suspended state. This can cause a NOC error at times when
trying to access the device's monitor registers in a suspended state. This
change fixes this issue. Introduce a variable dev_suspended to know if
the device is in suspended state or not. Check if the device is suspended
before switching the governor from sysfs.

PM / devfreq: Fix race condition between suspend/resume and governor_store
There is a race condition when the event governor_store is being executed
from sysfs and the device issues a suspend. The devfreq data structures
would become stale when the suspend tries to access them in the middle
of the governor_store operation. Fix this issue by taking a lock around
suspend and resume operations so that these operations are not concurrent
with the other events from sysfs.

Also rename the sysfs_lock as event_lock since the same lock is used
for non sysfs operations like suspend and resume as well.

devfreq: Weight stall cycles more for GPU bus DCVS
Update GPU Bus DCVS to weight high stall cycles (as a percentage
of total bus usage) heavier in order to vote up the bus when the
GPU is stalling a lot waiting for data.

PM / devfreq: tegra30: Fix integer overflow on CPU's freq max out
[ Upstream commit 53b4b2aeee26f42cde5ff2a16dd0d8590c51a55a ]

There is another kHz-conversion bug in the code, resulting in integer
overflow. Although, this time the resulting value is 4294966296 and it's
close to ULONG_MAX, which is okay in this case.

To build test, add COMPILE_TEST depedency to both ARM_RK3399_DMC_DEVFREQ

used the SMCCC interface so that add HAVE_ARM_SMCCC dependency to prevent

PM / devfreq: Don't fail devfreq_dev_release if not in list
[ Upstream commit 42a6b25e67df6ee6675e8d1eaf18065bd73328ba ]

Right now devfreq_dev_release will print a warning and abort the rest of
the cleanup if the devfreq instance is not part of the global
devfreq_list. But this is a valid scenario, for example it can happen if
the governor can't be found or on any other init error that happens
after device_register.

Initialize devfreq->node to an empty list head in devfreq_add_device so
that list_del becomes a safe noop inside devfreq_dev_release and we can
continue the rest of the cleanup.

PM / devfreq: Lock devfreq in trans_stat_show
commit 2abb0d5268ae7b5ddf82099b1f8d5aa8414637d4 upstream.

There is no locking in this sysfs show function so stats printing can
race with a devfreq_update_status called as part of freq switching or
with initialization.

Also add an assert in devfreq_update_status to make it clear that lock
must be held by caller.

Regulators should be enabled before clocks to avoid h/w hang. This
require change in exynos_bus_probe() to move exynos_bus_parse_of()

Similar change is needed in exynos_bus_exit() where clock should be
disabled before regulators.

PM / devfreq: passive: Use non-devm notifiers
[ Upstream commit 0ef7c7cce43f6ecc2b96d447e69b2900a9655f7c ]

The devfreq passive governor registers and unregisters devfreq
transition notifiers on DEVFREQ_GOV_START/GOV_STOP using devm wrappers.

If devfreq itself is registered with devm then a warning is triggered on
rmmod from devm_devfreq_unregister_notifier. Call stack looks like this:

	devm_devfreq_unregister_notifier+0x30/0x40
	devfreq_passive_event_handler+0x4c/0x88
	devfreq_remove_device.part.8+0x6c/0x9c
	devm_devfreq_dev_release+0x18/0x20
	release_nodes+0x1b0/0x220
	devres_release_all+0x78/0x84
	device_release_driver_internal+0x100/0x1c0
	driver_detach+0x4c/0x90
	bus_remove_driver+0x7c/0xd0
	driver_unregister+0x2c/0x58
	platform_driver_unregister+0x10/0x18
	imx_devfreq_platdrv_exit+0x14/0xd40 [imx_devfreq]

This happens because devres_release_all will first remove all the nodes
into a separate todo list so the nested devres_release from
devm_devfreq_unregister_notifier won't find anything.

Fix the warning by calling the non-devm APIS for frequency notification.
Using devm wrappers is not actually useful for a governor anyway: it
relies on the devfreq core to correctly match the GOV_START/GOV_STOP
notifications.

DEVFREQ_GOV_SUSPEND events by calling devfreq_monitor_stop
and devfreq_monitor_suspend respectively, prior to disabling
the bw_hwmon irq. Doing so allows for the following race condition:

	T0:  				   bw_hwmon irq thread:

/* df->governor == bw_hwmon
 * changing to
 * powersave governor
 */
governor_store()
 /* Calls bw_hwmon governor event
  * handler with DEVFREQ_GOV_STOP
  * event
  */
 df->governor->event_handler()
  gov_stop()
  stop_monitor()
                                        update_bw_hwmon()
                                        devfreq_monitor_stop()
   /* Cancels timer for future calls
    * to devfreq_monitor
    */
   devfreq_monitor_stop()
   /* Calls free_irq(), which waits
    * for the bw_hwmon IRQ thread
    * to finish.
    */
   hw->stop_hwmon()
                                        --finishes update_devfreq()--
                                        /* Incorrectly starts
					 * devfreq_monitoring
                                         */
                                        devfreq_monitor_start()
                                       --thread finishes execution--
   --finishes DEVFREQ_GOV_STOP
     handling--
 --switches governor to powersave--
/* devfreq monitor for this
 * instance. This will call
 * queue_delayed_work()
 * which internally queues
 * the timer for this devfreq
 * structure.
 */
devfreq_monitor()
/* df->governor == powersave
 * changing to bw_hwmon
 */
governor_store()
 /* powersave: DEVFREQ_GOV_STOP
  */
 df->governor->event_handler()
 /* bw_hwmon: DEVFREQ_GOV_START
  */
 df->governor->event_handler()
  gov_start()
   /* Will incorrectly adjust
    * the fields within the
    * timer and corrupt the
    * timer data structure
    */
   devfreq_monitor_start()

Since this corrupts the timer data structures, when the timer
gets expired, it will be expired twice. Fix this race condition
by introducing new lock to synchronize the access to the
mon_started variable, so that the irq thread does not restart
the devfreq monitor after it has been stopped.

PM / devfreq: Fix potential NULL pointer dereference in governor_store
[ Upstream commit 63f1e05f7fe9ca509c60154d6a833abf96eecdc9 ]

df->governor is being dereferenced before it is null checked,
hence there is a potential null pointer dereference.

Notice that df->governor is being null checked at line 1004:
if (df->governor) {, which implies it might be null.

Fix this by null checking df->governor before dereferencing it.

PM / devfreq: Introduce a sysfs lock
Currently, concurrent writes to sysfs entries leave the	possibility for
race conditions within the devfreq framework.  For example, concurrently
executing max_freq_store and governor_store can result in attempting to
perform an update_devfreq() before the new governor's start handler can be
executed.

A more concrete case is a race between polling_interval_store and
governor_store.  Because no lock is used after calling into the event
handler of the old governor and there's nothing preventing work from being
queued after the monitor is stopped, it's possible to accidentally cause
delayed work to be queued on the governor being switched to.  This can be
seen if you create two threads, one which changes a device's governor
between simple_ondemand and performance, and one which changes its polling
interval between 45 and 50.

All of these races can be addressed with the introduction of a lock that
prevents sysfs operations from interleaving in this fashion.

PM / devfreq: Propagate error from devfreq_add_device()
commit d1bf2d30728f310f72296b54f0651ecdb09cbb12 upstream.

Propagate the error of devfreq_add_device() in devm_devfreq_add_device()
rather than statically returning ENOMEM. This makes it slightly faster
to pinpoint the cause of a returned error.

PM / devfreq: memlat: Look for min stall% in addition to ratio criteria
Some workloads doing memory access might appear memory latency bound even
though they might not actually be memory latency bound.

This error can happen when the core that's running the workload is very
parallelized or can do out of order executions, etc so not all memory
accesses would actually stall the core.

This can also happen when the the memory access monitoring capabilities
aren't ideal and end up counting more kinds of memory accesses than what
would be ideal. In this case, the IPM ratio can be lower than what it would
be if we had ideal monitoring capabilities.

To account for these errors, if the core has a stall cycle counting
capabilities, check for a minimum stall% before the workload is considered
memory latency bound. This would help reduce the inaccuracies, but is not a
replacement for IPM ratio scheme because the stall% method doesn't allow us
to detect which level of memory the workload is latency bound on, but the
IPM ratio does (based on which memory accesses we use for calculating the
ratio).

restart the hardware monitor.  Fix this by adding locking to the event
handler.

PM / devfreq: bimc-bwmon: Don't always round up BWMON5 measurements
All BWMON5 counters currently have very coarse resolution. So, rounding up
to the next resolvable measurement results in very high bandwidth
measurement event for use cases that generate almost no traffic. So,
instead of always rounding up to the next resolvable measurement, round up
only when the measurement is non-zero.

PM / devfreq: arm-memlat-mon: Simplify event initialization code
Instead of repeating the event initialization code for each event, just
keep an array of events and initialize them all using a for loop.

PM / devfreq: memlat: Improve tracing of stats and votes
When the memlat governor votes for 0, it didn't generate any "update" trace
points to avoid spamming the trace buffer. But this can sometimes make it
harder to interpret some traces logs.

So, as a middle ground betweem making the trace harder to interpret vs
spamming the trace buffer, generate one trace point, when the vote
transitions from a non-zero value to a zero.

At the same time, the memlat governor was also generating "meas" trace
points for completely idle cores during every polling interval. This causes
a significant amount of spamming of the trace buffer. So, when a core is
idle, don't generate any "meas" trace points for it.
