Update nvgpu_gr_zbc as:
struct nvgpu_gr_zbc {
struct nvgpu_mutex zbc_lock; /* Lock to access zbc table */
struct zbc_color_table *zbc_col_tbl; /* SW zbc color table pointer */
struct zbc_depth_table *zbc_dep_tbl; /* SW zbc depth table pointer */
struct zbc_stencil_table *zbc_s_tbl; /* SW zbc stencil table pointer */
u32 min_color_index; /* Minimum valid color table index */
u32 min_depth_index; /* Minimum valid depth table index */
u32 min_stencil_index; /* Minimum valid stencil table index */
u32 max_color_index; /* Maximum valid color table index */
u32 max_depth_index; /* Maximum valid depth table index */
u32 max_stencil_index; /* Maximum valid stencil table index */
u32 max_used_color_index; /* Max used color table index */
u32 max_used_depth_index; /* Max used depth table index */
u32 max_used_stencil_index; /* Max used stencil table index */
};
Add global struct nvgpu_gr_zbc_table_indices
struct nvgpu_gr_zbc_table_indices {
u32 min_color_index;
u32 min_depth_index;
u32 min_stencil_index;
u32 max_color_index;
u32 max_depth_index;
u32 max_stencil_index;
};
Currently, hw zbc table registers are written during both
gr_init_setup_sw() and gr_init_setup_hw().
- Modify nvgpu_gr_zbc_load_default_table() to
nvgpu_gr_zbc_load_default_sw_table() to only update sw copy of zbc table
during gr_init_setup_sw().
- Modify nvgpu_gr_zbc_load_table() to write zbc values stored in sw zbc
table to hw registers.
Re-structure zbc function as per zbc type i.e. color, depth and stencil.
Add gr.zbc.init_table_indices() hal to initialize zbc indices. Valid ZBC
table indices start from 1. HW indices start from 0 for color, depth and
stencil tables. Note that the corresponding format registers follow ZBC
index range starting at 1.
- void (*init_table_indices)(struct gk20a *g,
struct nvgpu_gr_zbc_table_indices *zbc_indices);
- Add corresponding functions for legacy chips
- Add zbc color, depth and stencil table size hw defines
- Remove ltc.zbc_table_size() hal
- Update ltc.set_zbc_s_entry(), ltc.set_zbc_color_entry and
ltc.set_zbc_depth_entry() accordingly.

Add separate flag gpu_dbg_gr to enable common.gr specific debugging.
Add this flag to all the existing debug logs that use gpu_dbg_fn or
gpu_dbg_info for debugging. Also add many other debugging logs that
might be helpful in debugging.
Removing debug log in gv11b_gr_init_get_nonpes_aware_tpc() as it dumps
too much data that does not seem useful.
Batch all interrupt enable functions in gr_init_setup_hw() together for
readability.

Currently, size of zbc index table is defined as a macro. This macro is
independent of the number of address bits in the ltc zbc index register.
Adding below hal will update zbc index table size as per number of
address bits.
Add hal to get gr_zbc_index_table_size:
u32 (*zbc_table_size)(struct gk20a *g);
ZBC index table address 0 is reserved. Logic to start zbc table index
from 1 is moved to corresponding hals.

Make the nvgpu_init_mutex function return void.
In linux case, this doesn't affect anything since mutex_init
returns void.
For posix, we assert() and die if pthread_mutex_init fails.
This alleviates the need to error inject for _every_
nvgpu_mutex_init function in the driver.

Some functions are not accessing hardware directly
but are being called using HAL ops: For example
g->ops.pmu.pmu_elpg_statistics,
g->ops.pmu.pmu_pg_init_param,
g->ops.pmu.pmu_pg_supported_engines_list,
g->ops.pmu.pmu_pg_engines_feature_list,
g->ops.pmu.pmu_is_lpwr_feature_supported,
g->ops.pmu.pmu_lpwr_enable_pg,
g->ops.pmu.pmu_lpwr_disable_pg,
g->ops.pmu.pmu_pg_param_post_init,
g->ops.pmu.save_zbc
Change the function access by using sw ops, like:
Create new functions:
int nvgpu_pmu_elpg_statistics(struct gk20a *g, u32 pg_engine_id,
struct pmu_pg_stats_data *pg_stat_data);
void nvgpu_pmu_save_zbc(struct gk20a *g, u32 entries);
bool nvgpu_pmu_is_lpwr_feature_supported(struct gk20a *g,
u32 feature_id);
