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.
