Add a sysfs node to allow root user to set PRI_FE_GFXP_WFI_TIMEOUT, for gp10b
only, in units of sysclk cycles. Store the set value in a variable, and write
the set value to register after GPU is un-railgated.
NV_PGRAPH_PRI_FE_GFXP_WFI_TIMEOUT is engine_reset after Bug 1623341.
Change default value to be specified in cycles, rather than time. This value

NVGPU_SUBMIT_GPFIFO_FLAGS_RESCHEDULE_RUNLIST is only used by realtime
priority EGL context, which checks for CAP_SYS_NICE during context
creation in userspace, so it wasn't secure against unprivileged program
spoofing submit ioctl with this flag to stall GPU progress of others.
This flag does increase duration of submit by approx 16us,
mostly due to register accesses and PMU FIFO mutex.

samples. In virtualization case, it is possible for
a guest to get GPU timestamps by using read_ptimer.
However, if the CPU timestamp is read on guest side,
and the GPU timestamp is read on vm-server side,
then it introduces some latency that will create an
artificial offset for GPU timestamps (~2 us in
average). For better CPU / GPU timestamps correlation,
Added a command to collect all timestamps on vm-server

Support for hwpm reservations in the virtual case:
- Add session ops for checking and setting global and context reservations, and
releasing reservations
- in the native case, these just update reservation counts and flags
- in the vgpu case, when the reservation count is 0, check with the RM server
that a reservation is possible: for global reservations, no other guest
can have a reservation; for context reservations, no other guest can have
a global reservation
- in the vgpu case, when the reservation count is decremented to 0, notify
the RM server that the guest no longer has any reservations

The main driver structure is not refcounted properly,
so when the driver unload, file desciptors associated to the
driver are kept open with dangling references to the main object.
This change adds referencing to the gk20a structure.

We have a gk20a_busy() call in gk20a_buffer_convert_gpu_to_cde()
and we again call gk20a_busy() in gk20a_submit_channel_gpfifo()
If gk20a_do_idle() is triggered in between these two calls,
then this leads to a deadlock and results in idle failure
Hence to avoid this take power refcount in a more fine-grained
way i.e. in gk20a_cde_convert() instead of taking in
gk20a_buffer_convert_gpu_to_cde()
Keep gk20a_cde_execute_buffer() out of the gk20a_busy()/
gk20a_idle() pair since we take power refcount in submit path
anyways
Add correct error handling path in gk20a_cde_convert()

In gk20a_cde_convert(), we hold cde_app.mutex almost
for everything which is unnecessary
Also, this causes a deadlock scenario when gk20a_do_idle()
is called
In some cases it is possible that Thread 1
holds the lock and is trying to power on GPU, and
Thread 2 is trying to power off GPU and then grab
cde_app.mutex to cleanup GPU state
To fix this, grab the mutex only for gk20a_cde_get_context()
and then release it

(*) Refactor the non-stalling interrupt path to execute clear on the
top half, so on dGPU case processing of stalling interrupts does not
block non-stalling one.
(*) Use a worker thread to do semaphore wakeups and allow batching of
the non-stalling operations.
(*) Fix a bug where some gpus will not properly track the completion
of interrupts, preventing safe driver unloads

Currently callbacks from the PM_QOS framework (for
thermal events), result in a RPC call to set GPU frequency.
Since the governor will now be responsible for setting desired
rate, the max PM_QOS callback will now cap the possible
GPU frequency w/ a new RPC call to the server. The server
is responsible for setting the ultimate frequency
based on the cap & desired rates.
