GR context associated with channel is updated in various driver paths.
Sequence to do the same is disable the TSG, preempt the TSG, update
the GR context or instance block and then enable the TSG.
These operations and runlist updates for channel have to be done under
TSG specific ctx_init_lock to avoid the race.
suspend_contexts and resume_contexts needs special handling which is
not covered in this patch.

This patch introduces following relationships among various nvgpu
objects to support multiple address spaces with subcontexts.
IOCTLs setting the relationships are shown in the braces.
nvgpu_tsg 1<---->n nvgpu_tsg_subctx (TSG_BIND_CHANNEL_EX)
nvgpu_tsg 1<---->n nvgpu_gr_ctx_mappings (ALLOC_OBJ_CTX)
nvgpu_tsg_subctx 1<---->1 nvgpu_gr_subctx (ALLOC_OBJ_CTX)
nvgpu_tsg_subctx 1<---->n nvgpu_channel (TSG_BIND_CHANNEL_EX)
nvgpu_gr_ctx_mappings 1<---->n nvgpu_gr_subctx (ALLOC_OBJ_CTX)
nvgpu_gr_ctx_mappings 1<---->1 vm_gk20a (ALLOC_OBJ_CTX)
On unbinding the channel, objects are deleted according
to dependencies.
Without subcontexts, gr_ctx buffers mappings are maintained in the
struct nvgpu_gr_ctx. For subcontexts, they are maintained in the
struct nvgpu_gr_subctx.
Preemption buffer with index NVGPU_GR_CTX_PREEMPT_CTXSW and PM
buffer with index NVGPU_GR_CTX_PM_CTX are to be mapped in all
subcontexts when they are programmed from respective ioctls.
Global GR context buffers are to be programmed only for VEID0.
Based on the channel object class the state is patched in
the patch buffer in every ALLOC_OBJ_CTX call unlike
setting it for only first channel like before.
PM and preemptions buffers programming is protected under TSG
ctx_init_lock.
tsg->vm is now removed. VM reference for gr_ctx buffers mappings
is managed through gr_ctx or gr_subctx mappings object.
For vGPU, gr_subctx and mappings objects are created to reference
VMs for the gr_ctx lifetime.
The functions nvgpu_tsg_subctx_alloc_gr_subctx and nvgpu_tsg_-
subctx_setup_subctx_header sets up the subcontext struct header
for native driver.
The function nvgpu_tsg_subctx_alloc_gr_subctx is called from
vgpu to manage the gr ctx mapping references.
free_subctx is now done when unbinding channel considering
references to the subcontext by other channels. It will unmap
the buffers in native driver case. It will just release the
VM reference in vgpu case.
Note that TEGRA_VGPU_CMD_FREE_CTX_HEADER ioctl is not called
by vgpu any longer as it would be taken care by native driver.

In order to maintain separate mappings of GR TSG and global context
buffers for different subcontexts, we need to separate the memory
struct and the mapping struct for the buffers. This patch moves
the mappings of all GR ctx buffers to new structure
nvgpu_gr_ctx_mappings.
This will be instantiated per subcontext in the upcoming patches.
Summary of changes:
1. Various context buffers were allocated and mapped separately.
All TSG context buffers are now stored in gr_ctx->mem[] array
since allocation and mapping is unified for them.
2. Mapping/unmapping and querying the GPU VA of the context
buffers is now handled in ctx_mappings unit. Structure
nvgpu_gr_ctx_mappings in nvgpu_gr_ctx holds the maps.
On ALLOC_OBJ_CTX this struct is instantiated and deleted
on free_gr_ctx.
3. Introduce mapping flags for TSG and global context buffers.
This is to map different buffers with different caching
attribute. Map all buffers as cacheable except
PRIV_ACCESS_MAP, RTV_CIRCULAR_BUFFER, FECS_TRACE, GR CTX
and PATCH ctx buffers. Map all buffers as privileged.
4. Wherever VM or GPU VA is passed in the obj_ctx allocation
functions, they are now replaced by nvgpu_gr_ctx_mappings.
5. free_gr_ctx API need not accept the VM as mappings struct
will hold the VM. mappings struct will be kept in gr_ctx.
6. Move preemption buffers allocation logic out of
nvgpu_gr_obj_ctx_set_graphics_preemption_mode.
7. set_preemption_mode and gr_gk20a_update_hwpm_ctxsw_mode
functions need update to ensure buffers are allocated
and mapped.
8. Keep the unit tests and documentation updated.
With these changes there is clear seggregation of allocation and
mapping of GR context buffers. This will simplify further change
to add multiple address spaces support. With multiple address
spaces in a TSG, subcontexts created after first subcontext
just need to map the buffers.

Query the num_perfmon requires golden context to be ready. Accessing
golden context might require gr_instance_id, specific to a GR engine.
On TOT, get_num_hwpm_perfmon() called from perfmon HAL which might
require to call nvgpu_gr_exec_with_err_for_instance().
It internally calls nvgpu_grmgr_config_gr_remap_window() to change
gr_window_remap register points to a current gr_instance_id for MIG.
This approach indirectly mandates to call
nvgpu_gr_exec_with_err_for_instance() which can be
completely avoided. get_num_hwpm_perfmon() is just a query call
which can be moved after the golden context creation.
Using this logic, we can avoid unnecessary invocation of
nvgpu_gr_exec_with_err_for_instance() during perform specific
HAL accesses.
1) Moved get_num_hwpm_perfmon() after golden context creation.
2) Added nvgpu_assert() if (g->num_sys_perfmon == 0U).

If user calls IOCTL to allocate object context for two channels in same
TSG in parallel, nvgpu_gr_setup_alloc_obj_ctx() could end up racing and
trying to allocate object context for both channels at the same time.
This could result in corrupting object context.
Fix this by introducing per-TSG mutex ctx_init_lock to serialize context
initialization for all channels within TSG.
In ideal scenario nvrm_gpu is the only caller of all the IOCTLs, and
nvrm_gpu makes sure to initialize object context for each channel in
serial order. Because of this new lock does not cause any contention.
