f95cb5f4f8 gpu: nvgpu: maintain ctx buffers mappings separately from ctx mems
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.

fb466b5b25 gpu: nvgpu: Enable ptimer
This is enabling ptimer in mme_config and

Debugger is expected to make use of ptimer.
So this is required for nvgpu to enable ptimer
in the register.

7fa6976a98 gpu: nvgpu: remove dead code
nvgpu_gr_subctx_set_patch_ctx was earlier used in the HAL
gops.gr.ctx_patch_smpc. Usage was removed since that HAL
applies to only gm20b that doesn't support subcontexts.
Remove that function.

gp10b_gr_init_commit_global_attrib_cb is also not used by
any chip, so remove that also.

019bee2174 gpu: nvgpu: add additional registers to allowlist
To add GL/VK support for shader debugging via the SM trap handler
functionality, a write operation to the following PRI registers need to
be allowed in all chips (ga10b, gv11b, gm20b, gp10b):

- NV_PGRAPH_PRI_GPCS_MMU_DEBUG_CTRL
- NV_PGRAPH_PRI_GPCS_TPCS_SM_SCH_MACRO_SCHED
- NV_PGRAPH_PRI_GPCS_TPCS_SMS_DBGR_CONTROL0
- NV_PGRAPH_PRI_GPCS_TPCS_SMS_HWW_WARP_ESR_REPORT_MASK
- NV_PGRAPH_PRI_GPCS_TPCS_SMS_HWW_GLOBAL_ESR_REPORT_MASK

In this patch, we are adding the above registers into allowlist, if they
were absent. Note that these registers included only in non-safety using
CONFIG_NVGPU_SET_FALCON_ACCESS_MAP flag.

61ae0b7642 gpu: nvgpu: fix emulate mode enable
The emulate mode support is determined after chip detect and is flagged
by using NVGPU_SUPPORT_EMULATE_MODE flag. The present logic prevents
user from configuring the emulate mode sysfs knobs if this flag is not
set, however the emulate mode usecase requires the user to configure the
syfs knob prior to power-on, hence defer emulate mode check to a later
stage after chip detect.

two most common cases - cpu clock based and a retry based timeout - to
functions that cannot fail and thus return nothing. Adjust all callers
to use those, simplfying error handling quite a bit.

c4dee40c49 gpu: nvgpu: fix MISRA violations in common.gr
1. misra_c_2012_rule_8_6_violation: "gm20b_gr_init_fe_go_idle_timeout"
   is declared but never defined.

Fix by adding config CONFIG_NVGPU_HAL_NON_FUSA for header declaration
of "gm20b_gr_init_fe_go_idle_timeout"

2. misra_c_2012_rule_5_7_violation: Identifier "ops" is already used
   to represent a type.

Fix by renaming local variable ops to nonstall_ops in
gm20b_gr_intr_nonstall_isr()

3. missing_default: No default case found for the switch statement
   "switch (offset << 2)"

Fix by adding break and default statements to switch case in
gv11b_gr_intr_handle_sw_method()

9034b1676e gpu: nvgpu: compile out GFxP support in safety
GFxP preemption for graphics contexts is not supported in safety.
But the support was enabled along with CONFIG_NVGPU_GRAPHICS since GFxP
preemption was protected under same config.

Add a separate config CONFIG_NVGPU_GFXP to protect all GFxP specific
code, enum values, and HALs.

Disable the config in safety profile.

c08719cb0b gpu: nvgpu: move graphics specific HALs to fusa files
All graphics code is under CONFIG_NVGPU_GRAPHICS and all the HALs are
in non-fusa files. In order to support graphics in safety,
CONFIG_NVGPU_GRAPHICS needs to be enabled. But since most of the HALs
are in non-fusa files, this causes huge compilation problem.

Fix this by moving all graphics specific HALs used on gv11b to fusa
files. Graphics specific HALs not used on gv11b remain in non-fusa files
and need not be protected with GRAPHICS config.

Protect call to nvgpu_pmu_save_zbc() also with config
CONFIG_NVGPU_POWER_PG, since it is implemented under that config.

Delete hal/ltc/ltc_gv11b.c since sole function in this file is moved to
fusa file.

Enable nvgpu_writel_loop() in safety build since it is needed for now.
This will be revisited later once requirements are clearer.

Move below CTXSW methods under CONFIG_NVGPU_NON_FUSA for now. Safety
CTXSW ucode does not support these methods. These too will be revisited
later once requirements are clearer.

asserts

gp10b_gr_init_commit_global_bundle_cb() function checks if size <=
U32_MAX value. But since size is declared as u32, it will always be
<= U32_MAX value so there is no point in the check.
Remove unnecessary check.

1c991a58af gpu: nvgpu: Add SM diversity support
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute on
different hardware resources. This feature proposes modifications
in the software to modify the virtual SM id to TPC mapping across
the mission and redundant contexts. The virtual SM identifier to TPC
mapping is done by nvgpu when setting up the patch context.

The recommendation for the redundant setting is to offset the
assignment by one TPC, and not by one GPC. This will ensure that both
GPC and TPC diversity. The SM and Quadrant diversity will happen
naturally. For kernels with few CTAs, the diversity is guaranteed
to be 100%. In case of completely random CTA allocation,
e.g. large number of CTAs in the waiting queue, the diversity is
1 - 1/#SM, or 87.5% for GV11B, 97.9% for TU104.

Added NvGpu CFLAGS to enable/disable the SM diversity support
"CONFIG_NVGPU_SM_DIVERSITY".

This support is only enabled on gv11b and tu104 QNX non safety build.

  it is really not doing anything in safety
- Remove the switch statement in nvgpu_gr_obj_ctx_set_compute_preemption_mode
  since it is not possible to receive any other value than supported.
  Previous function calls ensure that input values are validated.
- nvgpu_gr_obj_ctx_commit_global_ctx_buffers() does not return any
  error, change the return type to void
- gops.gr.init.preemption_state HAL is not needed in safety since it
  only configures gfxp related timeout
- remove redundant call to gops.gr.init.wait_idle in
  nvgpu_gr_obj_ctx_commit_hw_state. We trigger wait despite earlier
  failure in same function call.

This HAL function does not return any real error at all.
So just change the return type to void.

In case of vGPU, this function only calls another HAL
gops.gr.config.init_sm_id_table(). So unset gops.gr.init.fs_state()
for vGPU, and call gops.gr.config.init_sm_id_table() directly.
