73d62c0c52 gpu: nvgpu: move fecs_trace_enable/disable APIs to gr/fecs_trace
Move below APIs from gk20a/fecs_trace_gk20a.c
gk20a_fecs_trace_enable()
gk20a_fecs_trace_disable()
gk20a_fecs_trace_is_enabled()
gk20a_fecs_trace_reset_buffer()
gk20a_fecs_trace_buffer_size()
gk20a_gr_max_entries()

and move them to new gr/fecs_trace unit with below renames
nvgpu_gr_fecs_trace_enable()
nvgpu_gr_fecs_trace_disable()
nvgpu_gr_fecs_trace_is_enabled()
nvgpu_gr_fecs_trace_reset_buffer()
nvgpu_gr_fecs_trace_buffer_size()
nvgpu_gr_fecs_trace_max_entries()

Use new functions in the driver instead of old ones

Export gk20a_fecs_trace_periodic_polling() in fecs_trace_gk20a.h
header since it is needed in gr/fecs_trace for transition
This include and the function itself will be later moved to
gr/fecs_trace unit

Move struct nvgpu_gpu_ctxsw_trace_filter and all filter TSG
macros in the form NVGPU_GPU_CTXSW_TAG_* to gr/fecs_trace.h

ef15a7d2d3 gpu: nvgpu: move struct gk20a_fecs_trace_record to gr/fecs_trace unit
Move struct gk20a_fecs_trace_record to gr/fecs_trace unit and rename
it as struct nvgpu_fecs_trace_record

Move all of the APIs in nvgpu/fecs_trace.h to nvgpu/gr/fecs_trace.h
and rename them in nvgpu_gr_fecs_trace_*() format
Delete nvgpu/fecs_trace.h

Add new HAL unit common/gr/fecs_trace/fecs_trace_gm20b.c for register
accesses needed for gr/fecs_trace unit
Add below new HALs in this HAL unit
g->ops.fecs_trace.get_read_index()
g->ops.fecs_trace.get_write_index()
g->ops.fecs_trace.set_read_index()

2104ded777 gpu: nvgpu: move struct gk20a_fecs_trace to gr/fecs_trace unit
Move struct gk20a_fecs_trace to new gr/fecs_trace unit and rename
it as struct nvgpu_gr_fecs_trace

Add enable_lock mutex and enable_count to this structure to support
QNX use cases
Remove init field from struct gk20a_fecs_trace

Rename gk20a_fecs_trace_init() to nvgpu_gr_fecs_trace_init() and
move it to new unit
Rename gk20a_fecs_trace_deinit() to nvgpu_gr_fecs_trace_deinit()
and move it to new unit

Update gk20a_fecs_trace_enable() to start thread only when
enable_count == 1, otherwise we just increment enable_count
Update gk20a_fecs_trace_disable() to stop thread when
enable_count == 0, otherwise we just decrement enable_count

Before this patch struct gk20a_fecs_trace was not visible in new
unit, and hence all mutex_acquire for list_lock were done in
fecs_trace_gk20a.c file
Since new struct is now available in new unit, move mutex_lock/release
calls to gr/fecs_trace unit now

556041f425 gpu: nvgpu: create new gr/fecs_trace unit
Create new gr/fecs_trace unit with common/gr/fecs_trace/fecs_trace.c
as common source file and include/nvgpu/gr/fecs_trace.h as common
header file
This unit will be common between Linux and QNX
Corresponding HAL files will be added under common/gr/fecs_trace/
as more functionality is moved to new unit

For now move struct gk20a_fecs_trace_hash_ent to new unit and
rename it as struct nvgpu_fecs_trace_context_entry
Add vmid field to this struct since it is required for QNX

Remove use of hashtables and simply use linked list to simplify
the code. FECS tracing is not a performance sensitive use case
so perf hit could be ignored

Rename hash_lock mutex to list_lock

struct gk20a_fecs_trace and mutex list_lock are still declared in
gk20a/fecs_trace_gk20a.c, hence they cannot be used in new unit yet

Rename and update all gk20a_fecs_trace_hash_*() APIs to appropriate
nvgpu_gr_fecs_trace_*() APIs

Remove gk20a_fecs_trace_hash_dump() since it is not being used
