04786d1a2e gpu: nvgpu: add hal.gr.init hal to enable/disable fe_go_idle timeout
Add new hal operation g->ops.gr.init.fe_go_idle_timeout() in hal.gr.init
unit to enable/disable fe_go_idle timeout

Use this hal in gr_gk20a_init_golden_ctx_image() instead of direct
register access

Remove timeout disable/enable code in gk20a_init_sw_bundle() since
parent API gr_gk20a_init_golden_ctx_image() is already taking care of
that

56219f7c10 gpu: nvgpu: add more gr/init hal functions
Register write from gr_gk20a_init_fs_state function are moved to hal.

New hal added for setting the pd_tpc_per_gpc, pd_skip_table_gpc and
cwd_gpcs_tpcs_num.

pd_tpc_per_gpc helps to describe the number of tpcs in each logical
gpc.
pd_skip_table helps to skip certain TPCs during distribution.
cwd_gpcs_tpcs_num helps to set number of tpcs and gpcs in CWD.

remove write for depreciated NV_PBE_PRI_ZROP_SETTING_NUM_ACTIVE_FBPS
and NV_PBE_PRI_CROP_SETTINS_NUM_ACTIVE_FBPS fields from
BES_ZROP_SETTINGS and BES_CROP_SETTINGS registers. Both these fields
changed to NUM_ACTIVE_LTCS from gm20b onwards and those are being
set in existing hal functions.

cc74fd9303 gpu: nvgpu: unify cbc_init in cbc and fb units
Pre-volta, cbc config is part of hw ltc and from volta onwards this is
moved to hw fb. Because of this, cbc_init functions are present in both
cbc unit and fb unit. Pre-volta uses cbc_init from cbc unit and from
volta onwards it uses cbc_init from fb unit.

With this patch, unified two cbc_init functions to cbc unit and created
new fb hal for cbc_configure. cbc unit uses fb hal for cbc_config and
fb unit is independent of cbc unit.

- rename vgpu_gr_gm20b_init_cyclestats() to vgpu_gr_init_cyclestats()
moving to gr_vgpu.c common to all vgpu chips.

to all vgpu chips.

- rename vgpu_gr_gp10b_set_ctxsw_preemption_mode() to
vgpu_gr_set_ctxsw_preemption_mode() moving to ctx_vgpu.c common
to all vgpu chips.

- rename vgpu_gr_gp10b_set_preemption_mode() to
vgpu_gr_set_preemption_mode() moving to ctx_vgpu.c common
to all vgpu chips.

- rename vgpu_gr_gp10b_init_ctx_state() to vgpu_gr_init_ctx_state()
moving to ctx_vgpu.c common to all vgpu chips.

- combine vgpu_gr_gv11b_commit_ins() to vgpu_gr_commit_inst()
executing alloc/free subctx header code only if chip supports
subctx.

- remove inclusion of hw header files from vgpu gr code by
introducing hal ops for the following:
  - alloc_global_ctx_buffers:
    - hal op for getting global ctx cb buffer
    - hal op for getting global ctx pagepool buffer size
  - set_ctxsw_preemption_mode:
    - hal op for getting ctx spill size
    - hal op for getting ctx pagepool size
    - hal op for getting ctx betacb size
    - hal op for getting ctx attrib cb size
These chip specific function definitions are currently implemented in
chip specific gr files which will need to be moved to hal units.
Also use these hal ops for corresponding functions for native. This
makes gr_gv11b_set_ctxsw_preemption_mode() function redundant. Use
gr_gp10b_set_ctxsw_preemption_mode() for gv11b as well.

319eca3498 gpu: nvgpu: move get_ctx_id API to gr/ctx unit
API gr_gk20a_get_ctx_id() extracts ID of the context and as such
belongs to gr/ctx unit
Move it to gr/ctx and rename it as nvgpu_gr_ctx_get_ctx_id()

All the book keeping for valid ID is also done in same API using
ctx_id_valid flag in gr/ctx unit

Use new API in gr_gp10b_set_cilp_preempt_pending() to get the
context ID

a5eb150635 gpu: nvgpu: add new gr/config unit to initialize GR configuration
Add new unit gr/config to initialize GR configuration like GPC/TPC
count, MAX count and mask

Create new structure nvgpu_gr_config that stores all the configuration
and that is owned by the new unit

Move below fields from struct gr_gk20a to nvgpu_gr_config in gr/config.h
Struct gr_gk20a now only holds the pointer to struct nvgpu_gr_config

u32 max_gpc_count;
u32 max_tpc_per_gpc_count;
u32 max_zcull_per_gpc_count;
u32 max_tpc_count;

u32 gpc_count;
u32 tpc_count;
u32 ppc_count;
u32 zcb_count;

u32 pe_count_per_gpc;

u32 *gpc_tpc_count;
u32 *gpc_ppc_count;
u32 *gpc_zcb_count;
u32 *pes_tpc_count[GK20A_GR_MAX_PES_PER_GPC];

u32 *gpc_tpc_mask;
u32 *pes_tpc_mask[GK20A_GR_MAX_PES_PER_GPC];
u32 *gpc_skip_mask;

u8 *map_tiles;
u32 map_tile_count;
u32 map_row_offset;

Remove gr->sys_count since it was already no longer used

common/gr/config/gr_config.c unit now exposes the APIs to initialize
the configuration and also to query the configuration values

nvgpu_gr_config_init() is called to initialize GR configuration from
gr_gk20a_init_gr_config() and gr_gk20a_init_map_tiles() is simply
renamed as nvgpu_gr_config_init_map_tiles()

Expose new API nvgpu_gr_config_deinit() to deinit the configuration

Expose nvgpu_gr_config_get_*() APIs to query above configuration
fields stored in nvgpu_gr_config structure

Update vgpu_gr_init_gr_config() to initialize the configuration
from gr->config structure

Chip specific HALs that access GR register for initialization
are implemented in common/gr/config/gr_config_gm20b.c
Set these HALs for all GPUs

254253732c gpu: nvgpu: add new unit for GR subcontext
Add new unit common/gr/subctx.c to manage GR subcontext
This unit provides interfaces to allocate/free/load GR subcontext

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

Right now channel_gk20a structure directly includes a nvgpu_mem
for context header.
Declare a new structure nvgpu_gr_subctx for subcontext and include
this from channel_gk20a

Make all necessary changes to refer ctx_header from subctx instead
of directly referencing it from channel
