32 bit variable is used for storing number of bytes copied to DSP,
which can overflow when playback duration goes beyond 24 hours.
Change data type for this variable to uint64_t to prevent overflow

Some driver modules require the ability to parse the kernel command
line outside the <modulename>.parm=<val> set on Android. For example
androidboot.console=. Past attempts ('03) to upstream and export
this key piece of content has come under resistance because
preference has been to support the existing api __setup(str,func),
which is only available to built-in, and push modules towards only
using the documented kernel parameter interface cited above or to
Device Tree and not react to any other out-of-band content.

When compressed and pcm session is started the buffer pull will
Be from the DSP, in mmap mode for the scenario Hardware pointer
Is same as application pointer implies application has not filled the
Buffer to be send to DSP, and platform driver has to break and restart
The de queue process when the application has sufficient buffers.
When hardware pointer is same as application pointer it is an under run
Scenario where the ALSA framework has to trigger the under run and in HAL
The session has to re-prepare and re-triggered. based on the stop
Threshold, but in our system the stop threshold is INT_MAX which
Indicates that under run is not triggered in practical cases.
We have a brodcast usecase in which the mentioned under run case
Is hit mulitple times, and every time re-prepare and re-trigger will be
Expensive
Update the ASoC core framework to restart de queue process stopped
By platform Driver when the under run is hit, based on the available
Buffer and render flag, so the System will recover from the hang state.
To restart de queue process the ASoC core will be calling the restart
Callback registered by platform driver and this callback will be running in
Atomic context.

When doing Clang builds of the kernel, it is possible to link with
either ld.bfd (binutils) or ld.lld (LLVM), but it is not possible to
discover this from a running kernel. Add the "$LD -v" output to

Bug: 149990629
QoS request for CPU_DMA_LATENCY can be better optimized if the request
can be set only for the required cpus and not all cpus. This helps save
power on other cores, while still gauranteeing the quality of service.
Enhance the QoS constraints data structures to support target value for
each core. Requests specify if the QoS is applicable to all cores
(default) or to a selective subset of the cores or to a core(s), that the
IRQ is affine to.
QoS requests that need to track an IRQ can be set to apply only on the
cpus to which the IRQ's smp_affinity attribute is set to. The QoS
framework will automatically track IRQ migration between the cores. The
QoS is updated to be applied only to the core(s) that the IRQ has been
migrated to.
Idle and interested drivers can request a PM QoS value for a constraint
across all cpus, or a specific cpu or a set of cpus. Separate APIs have
been added to request for individual cpu or a cpumask. The default
behaviour of PM QoS is maintained i.e, requests that do not specify a
type of the request will continue to be effected on all cores. Requests
that want to specify an affinity of cpu(s) or an irq, can modify the PM
QoS request data structures by specifying the type of the request and
either the mask of the cpus or the IRQ number depending on the type.
Updating the request does not reset the type of the request.
The userspace sysfs interface does not support CPU/IRQ affinity.

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.

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.

Bug: 152343889
(cherry picked from commit 8bf200e713)
Signed-off-by: Saravana Kannan <saravanak@google.com>
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.
