Several additional audio clocks need to be initialized before

Increase the wait delays in do_idle() to 2000 mS and make use
of msleep instead of mdelays

Also, to check if GPU is rail gated or not, add a do-while()
loop which will keep checking the status and bail out as soon
as GPU is rail gated

This increase in delays is required to allow GPU sufficient
time to complete its work and get rail gated

These delays are specially needed during stress testing where
it is possible that a large amount of GPU work is blocked
during do_idle() and then it might take more time to complete
it while next do_idle() is waiting for it

Also, remove waiting on API gk20a_wait_channel_idle() for each
channels since it is sufficient to wait for refcount to be 1

gpu: nvgpu: remove redundant busy()/idle() calls

gk20a_busy() call in channel_syncpt_incr() and corresponding
gk20a_idle() call in channel_update() are redundant since they
are already encapsulated inside another pair of busy/idle calls

This busy/idle pair will be called only from submit_gpfifo()
and submit_gpfifo() already has its own busy/idle which it
preserves for whole path and hence this redundant pair can be
removed

Also, this prevents a dead lock scenario while do_idle() is in
progress as follows :
- in submit_gpfifo() we call first gk20a_busy() which acquires
  busy read semaphore
- in do_idle() we acquire busy write semaphore and wait for
  current jobs to finish
- now submit_gpfifo() encounters second gk20a_busy() and requests
  busy read semaphore again
- this results in dead lock where do_idle() is waiting for
  submit_gpfifo() to complete and submit_gpfifo() is waiting for
  busy lock held by do_idle() and hence it cannot complete

gpu: nvgpu: fix race between do_idle() and unrailgate()

While we are executing do_idle() API, it is possible that
unrailgate() gets invoked in midst of idling the GPU and
this can result in failure of do_idle()

To prevent simultaneous execution of these methods,
add a mutex railgate_lock and acquire it during
do_idle() and unrailgate() APIs

Also, keep this lock held if do_idle() is successful.
In success, lock will be released in do_unidle(),
otherwise release this lock before returning

Note that this lock should not be held in railgate() API
since we do not want it to be blocked during do_idle()

5 years agomedia: tegra: nvavp: fix deadlock issue
Allen Yu [Wed, 2 Jul 2014 07:14:24 +0000]
media: tegra: nvavp: fix deadlock issue

In nvavp_pushbuffer_update(), we acquire channel_info->pushbuffer_lock first
then nvavp->open_lock. While in clock_disable_handler(), open_lock is acquired
before pushbuffer_lock, causing the deadlock if clock_disable_work happens to
be executing while running nvavp_pushbuffer_update().

This change reorder the locks in clock_disable_handler to avoid deadlock issue.
And also in tegra_nvavp_release(), need to release nvavp->open_lock first before
calling nvavp_uninit(), since nvavp_uninit() need to cancel clock_disable_work
in a synchronous manner.

5 years agogpu: nvgpu: fix possible PMU isr race
Deepak Nibade [Wed, 25 Jun 2014 13:27:23 +0000]
gpu: nvgpu: fix possible PMU isr race

Possible race description :
- while PMU is booting, it sends messages to kernel which we process
  in gk20a_pmu_isr()
- but when messages are processed it is possible that we are on the way
  to rail gate the GPU and we have already called pmu_destroy()
- this could lead to hangs if while processing messages, GR is
  already off

To fix this, introduce another mutex isr_enable_lock and a flag to
turn on/off ISRs
- when we enable PMU, get the lock and set the flag
- in pmu_destroy(), get the lock and remove the flag
- in pmu_isr(), take the lock, check if flag is set or not. If flag
  is not set return, otherwise proceed with the messages

net: wireless: bcmdhd: correct sdio_ids

Usage of SDIO_DEVICE(SDIO_VENDOR_ID_BROADCOM, SDIO_ANY_ID) is
causing device hang when BRCM chipsets BCM433341 are used.
This is because SDIO_DEVICE MACRO uses, SDIO_ANY_ID for class.

Use SDIO_CLASS_NONE instead resolves device hang issue.
