84f48df530 gpu: nvgpu: use vpr resize API
This patch adds nvgpu API in linux and qnx to query vpr resize.
The new API nvgpu_is_vpr_resize_enabled() is used in
nvgpu_submit_channel_gpfifo().
Previously, if non-deterministic channel has timeout disabled and
GPU cannot railgate on some platform, then channel doesn't power ref
count and results in video freeze. This requires non-determinstic
channel job tracking to be enabled if vpr resize is supported or if GPU
can railgate.

8b484c0b53 gpu: nvgpu: support usermode submit buffers
Import userd and gpfifo buffers from userspace if provided via
NVGPU_IOCTL_CHANNEL_ALLOC_GPFIFO_EX. Also supply the work submit token
(i.e., the hw channel id) to userspace.

To keep the buffers alive, store their dmabuf and attachment/sgt handles
in nvgpu_channel_linux. Our nvgpu_mem doesn't provide such data for
buffers that are mainly in kernel use. The buffers are freed via a new
API in the os_channel interface.

Fix a bug in gk20a_channel_free_usermode_buffers: also unmap the
usermode gpfifo buffer.

58ee7561f7 gpu: nvgpu: Add CHANNEL_SETUP_BIND IOCTL
For a long time now, the ALLOC_GPFIFO_EX channel IOCTL has done much
more than just gpfifo allocation, and its signature does not match
support that's needed soon. Add a new one called SETUP_BIND to hopefully
cover our future needs and deprecate ALLOC_GPFIFO_EX.

Change nvgpu internals to match this new naming as well.

47f6bc0c2e gpu: nvgpu: Fix the race between runtime PM and L2 flush
gk20a_mm_l2_flush flushes the L2 cache when "struct gk20a->power_on"
is true. But it doesn't acquire power lock when doing that, which
creates a race that runtime PM might suspend the GPU in the middle
of L2 flush. The FB flush looks having the same issue with L2 flushing.

This patch fixes that by calling pm_runtime_get_if_in_use at the
beginning of the ioctl. This API from PM does a compare and add to
the usage count. If the device was not in use, it simply returns
without incrementing the usage count as its unnecessary to wake up
the GPU(using e.g. a call to gk20a_busy()) as the caches are
flushed when the device would be resumed anyways.

PMU idle intr status register is used to monitor overflow. Overflow

3794afbeb1 gpu: nvgpu: add safe channel id lookup
Add gk20a_channel_from_id() to retrieve a channel, given a raw channel
ID, with a reference taken (or NULL if the channel was dead). This makes
it harder to mistakenly use a channel that's dead and thus uncovers bugs
sooner. Convert code to use the new lookup when applicable; work remains
to convert complex uses where a ref should have been taken but hasn't.

The channel ID is also validated against FIFO_INVAL_CHANNEL_ID; NULL is
returned for such IDs. This is often useful and does not hurt when
unnecessary.

However, this does not prevent the case where a channel would be closed
and reopened again when someone would hold a stale channel number. In
all such conditions the caller should hold a reference already.

The only conditions where a channel can be safely looked up by an id and
used without taking a ref are when initializing or deinitializing the
list of channels.

d6278955f6 gpu: nvgpu: RDMA implementation
This change adds RDMA supports for tegra iGPU.
1. Cuda Process allocates the memory and passes
   the VA and size to the custom kernel driver.
2. The custom kernel driver maps the user allocated
   buf and does the DMA to/from it.
3. Only supports iGPU + cudaHostAlloc sysmem
4. Works only for a given process.
5. Address should be sysmem page aligned and size should
   be multiple of sysmem page size.
6. The custom kernel driver must register a free_callback when get_page()
   function is called.

8789cafcfb gpu: nvgpu: Standardize HAS_SYNCPOINTs check
Nvgpu uses many ways to check if sync points are enabled. The four
ways used to be:

  platform->has_syncpoints
  g->has_syncpoints
  nvgpu_is_enabled(g, NVPGU_HAS_SYNCPOINTS)
  gk20a_platform_has_syncpoints()

This patch standardizes all usage to now be nvgpu_has_syncpoints()
which is based on gk20a_platform_has_syncpoints() - just renamed to
be general to nvgpu.

All usage of the other forms have now been consolidated. However,
under the hood nvgpu_has_syncpoints() does check the is_enabled
flag. This flag is now set where g->has_syncpoints used to be set
based on the platform data.

The basic dependency chain is this:

  nvgpu_has_syncpoints -> NVGPU_HAS_SYNCPOINTS ->
    platform->has_syncpoints

However, note: there are several places where syncpoints can be
disabled if some other driver initialization fails (for ex. host1x).
Also note that nvgpu_has_syncpoints() also considers a disable
variable set by debugfs.

2ab564937e gpu: nvgpu: enable HWPM Mode-E context switch
- This patch enables HWPM Mode-E context switch for gv11b.
- Write new pm mode to context buffer header. Ucode use
this mode to enable mode-e context switch. This is Mode-B
context switch of PMs with Mode-E streamout on one context.
If this mode is set, Ucode makes sure that Mode-E pipe
(perfmons, routers, pma) is idle before it context switches PMs.
- This allows us to collect counters in a secure way
(i.e. on context basis) with stream out.
- For Mode-E ctxsw it is required that engine_sel
is set to 0xFFFFFFFF.
- Default 0 is a valid signal and causes problems.

1) Update header path of gk20a.h files present in os/
to <nvgpu/gk20a.h>

2) os_fence_android_sema.c indirectly was dependent on gk20a.h via
semaphore.h. So, added #include <nvgpu/gk20a.h> in
os_fence_android_sema.c and replaced the header with forward
declaration of struct gk20a in semaphore.h
