In nvgpu_gr_ctx_alloc_ctxsw_buffers, just return if
ctxsw buffers have already been allocated.

4883f14fbb gpu: nvgpu: map global_ctx buffers from gr/ctx unit
Currently all the global contex buffers are mapped into each graphics
context. Move all the mapping/unmapping support to gr/ctx unit since
all the mappings are owned by context itself

Add nvgpu_gr_ctx_map_global_ctx_buffers() that maps all the global
context buffers into given gr_ctx
Add nvgpu_gr_ctx_get_global_ctx_va() that returns VA of the mapping
for requested index

Remove g->ops.gr.map_global_ctx_buffers() since it is no longer
required. Also remove below APIs
gr_gk20a_map_global_ctx_buffers()
gr_gk20a_unmap_global_ctx_buffers()
gr_tu104_map_global_ctx_buffers()

Remove global_ctx_buffer_size from nvgpu_gr_ctx since it is no
longer used

1c17ae310c gpu: nvgpu: add new unit for GR context
Add new unit common/gr/ctx.c to manage GR context

This unit provides interfaces to allocate/free/map/unmap GR context,
patch context, pm context, ctxsw {preempt/spill/betacb/pagepool/rtvcb}
buffers.
It also provides APIs to set size of above buffers

Add new header file include/nvgpu/gr/ctx.h to declare all the interfaces.

Move nvgpu_gr_ctx, patch_desc, pm_ctx_desc, zcull_ctx_desc structures
to this unit

Add new structure nvgpu_gr_ctx_desc to hold context description
parameters. For now we add sizes of all the buffers here.
Add this structure to gr_gk20a for global reference

Remove gr_gp10b_alloc_buffer() since it is no longer used

Rename g->ops.gr.alloc_gfxp_rtv_cb() to g->ops.gr.init_gfxp_rtv_cb()
since this HAL now only sets the size of rtvcb ctxsw buffer

Remove gr->ctx_vars.buffer_size and gr->ctx_vars.buffer_total_size
since they were redundant. We already have gr->ctx_vars.golden_image_size
to denote golden image size

9241635805 gpu: nvgpu: move local golden image to global ctx unit
Local golden image is copy of global GR context buffer hence move its
ownership to global context unit

Add new structure nvgpu_gr_global_ctx_local_golden_image to hold all meta
data for local golden image and move it to struct gr_gk20a

Expose and use new APIs to initialize/deinitialize and load local golden image

98c034869a gpu: nvgpu: remove GOLDEN_CTX from global buffers
Current code creats golden image using dedicated gr_ctx called
GOLDEN_CTX. But on RM server it's no easy to create a GOLDEN_CTX since
virtual addresses are managed by guest OSes. There's no special reason
why we have to use a separate gr_ctx for golden image. This patch moves
it to use current channel gr_ctx. And the function will be re-useable
by RM server.

ef580aee38 gpu: nvgpu: add new unit for GR global context buffers
Add new unit common/gr/global_ctx.c to manage GR global context buffers

This unit provides interfaces to allocate/free/map/unmap all the global
context buffers. It also provides APIs to get/set size of the buffers,
and to get memory handle of the buffers

Use interfaces exposed by this unit instead of directly accessing global
context buffers in common code

Add new header file include/nvgpu/gr/global_ctx.h to declare all the
interfaces.

Rename "struct gr_ctx_buffer_desc" to "struct nvgpu_gr_global_ctx_buffer_desc"
which holds all data for each global context
Remove void *priv since it is no longer used
Add size to the desc structure to store the requested size

Remove global_ctx_buffer_size from struct nvgpu_gr_ctx since it is no longer
used for any real purpose

6777bd5ed2 gpu: nvgpu: add separate unit for gr/ctxsw_prog
Add separate new unit gr/ctxsw_prog that provides interface to access
h/w header files hw_ctxsw_prog_*.h

Add below chip specific files that access above h/w unit and provide
interface through g->ops.gr.ctxsw_prog.*() HAL for rest of the units

common/gr/ctxsw_prog/ctxsw_prog_gm20b.c
common/gr/ctxsw_prog/ctxsw_prog_gp10b.c
common/gr/ctxsw_prog/ctxsw_prog_gv11b.c

Remove all the h/w header includes from rest of the units and code.
Remove direct calls to h/w headers ctxsw_prog_*() and use HALs
g->ops.gr.ctxsw_prog.*() instead

In gr_gk20a_find_priv_offset_in_ext_buffer(), h/w header
ctxsw_prog_extended_num_smpc_quadrants_v() is only defined on gk20a
And since we don't support gk20a remove corresponding code

Add missing h/w header ctxsw_prog_main_image_pm_mode_ctxsw_f() for
some chips
Add new h/w header ctxsw_prog_gpccs_header_stride_v()
