a55491015c gpu: nvgpu: exit early in cbc debugfs under hv
This patch updates the logic for the cbc debugfs node
to fail early if running under HV. The reason is that
the CBC region is maintained by HV and cannot be accessed
by nvgpu.

This avoids a subsequent null-ptr deref for Linux + HV.

9bf41e7ae6 gpu: nvgpu: Fix build for Linux v6.3
Upstream Linux commit bc292ab00f6c ("(HEAD) mm: introduce vma->vm_flags
wrapper functions") breaking building the NVGPU driver because the
vm_flags variable is made a const and can no longer be set directly. Fix
the build for Linux v6.3 by using the helper functions for setting the
flags.

02ab4c3880 gpu: nvgpu: Correct permissions for cbc_ctrl debug node
The cbc_ctrl debugfs node is created with both read and write
permissions, however, this node only supports being written and
not read. Fix this by removing read permissions for this debugfs
node.

64d2e25382 gpu: nvgpu: Expose cbc status and ctrl debug nodes
This patch adds two new debug nodes:
- cbc_status to retrieve cbc state information
- cbc_ctrl to flush and mmap cbc

These two nodes are to be used for purpose of testing
and debugging. One immediate goal is to use them for
verifying if CBC is programmed correctly via a user
space test.

Debug boolean flag dump_ctxsw_stats_on_channel_close is right now stored

This flag logically is property of gr.ctx units since it indicates
whether each context should dump ctxsw stats on channel/context close

gr_gk20a.ctx_vars

Expose below API from gr.ctx unit to check if flag is set
nvgpu_gr_ctx_desc_dump_ctxsw_stats_on_channel_close()

Move debugfs creation code to create corresponding debugfs to
gr_gk20a_debugfs_init() and change debugfs type from "u32" to "file"

Struct gr.gr_ctx_desc is created only during first poweron.
Return error if this struct is not available.

Remove unnecessary initialization of this variable from platform
specific probe functions

Remove below variables from struct gr_gk20a
u32 bundle_cb_default_size;

u32 bundle_cb_token_limit;
u32 attrib_cb_default_size;

u32 attrib_cb_gfxp_default_size;
u32 attrib_cb_gfxp_size;
u32 attrib_cb_size;
u32 alpha_cb_size;

u32 (*get_bundle_cb_default_size)(struct gk20a *g);
u32 (*get_min_gpm_fifo_depth)(struct gk20a *g);
u32 (*get_bundle_cb_token_limit)(struct gk20a *g);

u32 (*get_alpha_cb_size)(struct gk20a *g, u32 tpc_count);
u32 (*get_global_attr_cb_size)(struct gk20a *g, u32 max_tpc);

Define these hals for all gm20b/gp10b/gv11b/gv100/tu104 chips
Also add hal.gr.init support for gv100 chip

Remove all accesses to variables from struct gr_gk20a and start using
newly defined hals

Remove below hals to initialize sizes since they are no more required
g->ops.gr.bundle_cb_defaults(g);
g->ops.gr.cb_size_default(g);
g->ops.gr.calc_global_ctx_buffer_size(g);

Also remove definitions of above hals from all the chip files
