a1ef716f9d gpu: nvgpu: set graphics specific PRI values for graphics contexts
Add new HAL gops.gr.init.set_default_gfx_regs() to set graphics specific
PRI values for graphics contexts in function nvgpu_gr_obj_ctx_alloc().

Add new HAL gops.gr.init.capture_gfx_regs() to capture and save init
values for the PRIs. Add new struct nvgpu_gr_obj_ctx_gfx_regs to hold the
PRI init values.

Define HAL functions gv11b_gr_init_set_default_gfx_regs() and
gv11b_gr_init_capture_gfx_regs(). Set the HAL functions for
gv11b and ga10b.

Register accessors required to set PRIs are auto-generated.

9b7c8cdd8c gpu: nvgpu: Update GR intr code as per Orin HSIs
Most SM RAMs are protected with parity (except L1 D-cache TAG mem
which is protected with SEC-DED ECC). The memory corruption errors
reported by these RAMs are therefore uncorrected errors only.
Remove the code to handle corrected errors from GR SM ECC.

The SM RAMS ECC errors currently report error to SDL using ID
GPU_SM_L1_TAG_ECC_(UN)CORRECTED. Update the error reporting to
use the newly created error IDs for Drive 6.0.

94255220f7 gpu: nvgpu: ga10b: add TPC interleaved priv segment support
The ctxsw ucode saves all the ctxsw'ed TPC priv registers in the TPC
priv segment of the ctxsw image. In ga10b, these registers can be stored
in either of the two arrangements:
- INTERLEAVED: means the format is sorted by address first, then by TPC number
- MIGRATION: exact opposite of interleaved.

Update HAL functions gr_ga10b_process_context_buffer_priv_segment,
gr_ga10b_find_priv_offset_in_buffer to detect the register layout and
calculate the register offset accordingly.

- Compiles-out unused error reporting APIs and the related
  data structures from safety build. For this purpose, it
  introduces the new flag: CONFIG_NVGPU_INTR_DEBUG
- Updates nvgpu_report_err_to_sdl() API with one more argument,
  hw_unit_id. This aids in finding whether an error to be reported
  is corrected or uncorrected from LUT.
- Triggers SW quiesce, if an uncorrected error is reported to
  Safety_Services, in safety build.
- Renames files in cic folder by replacing gv11b with ga10b,
  since error reporting for gv11b is not supported in dev-main.

7dc013d242 gpu: nvgpu: merge error reporting apis
In DRIVE 6.0, NvGPU is allowed to report only 32-bit metadata to
Safety_Services. So, there is no need to have distinct APIs for
reporting errors from units like GR, MM, FIFO to SDL unit. All
these error reporting APIs will be replaced with a single API. To
meet this objective, this patch does the following changes:
- Replaces nvgpu_report_*_err with nvgpu_report_err_to_sdl.
- Removes the reporting of error messages.
- Replaces nvgpu_log() with nvgpu_err(), for error reporting.
- Removes error reporting to Safety_Services from nvgpu_report_*_err.

However, nvgpu_report_*_err APIs and their related files are not
removed. During the creation of nvgpu-mon, they will be moved under
nvgpu-rm, in debug builds.

Note:
- There will be a follow-up patch to fix error IDs.
- As discussed in https://nvbugs/3491596 (comment #12), the high
level expectation is to report only errors.

-Replace gr.vab_release and gr.vab_recover with gr.vab_configure HAL.

b67a3cd053 gpu: nvgpu: ga10b: Correct VAB implementation
This patch performs the following improvements for VAB:
1) It avoids an infinite loop when collecting VAB information.
   Previously, nvgpu incorrectly assumed that the valid bit would
   be eventually set for the checker when polling. It may not be set
   if a VAB-related fault has occurred.
2) It handles the VAB_ERROR mmu fault which may be caused for various
   reasons: invalid vab buffer address, tracking in protected mode,
   etc. The recovery sequence is to set the vab buffer size to 0 and
   then to the original size. This clears the VAB_ERROR bit. After
   reseting, the old register values are again set in the recovery
   code sequence.
3) Use correct number of VAB buffers. There's only one VAB buffer on
   ga10b, not two.
4) Simplify logic.

3d9c67a0e7 gpu: nvgpu: enable Orin support in safety build
Most of the Orin chip specific code is compiled out of safety build
with CONFIG_NVGPU_NON_FUSA and CONFIG_NVGPU_HAL_NON_FUSA. Remove the
config protection from Orin/GA10B specific code. Currently all code
is enabled. Code not required in safety will be compiled out later
in separate activity.

Other noteworthy changes in this patch related to safety build:

- In ga10b_ce_request_idle(), add a log print to dump num_pce so that
  compiler does not complain about unused variable num_pce.
- In ga10b_fifo_ctxsw_timeout_isr(), protect variables active_eng_id and
  recover under CONFIG_NVGPU_KERNEL_MODE_SUBMIT to fix compilation
  errors of unused variables.
- Compile out HAL gops.pbdma.force_ce_split() from safety since this HAL
  is GA100 specific and not required for GA10B.
- Compile out gr_ga100_process_context_buffer_priv_segment() with
  CONFIG_NVGPU_DEBUGGER.
- Compile out VAB support with CONFIG_NVGPU_HAL_NON_FUSA.
- In ga10b_gr_intr_handle_sw_method(), protect left_shift_by_2 variable
  with appropriate configs to fix unused variable compilation error.
- In ga10b_intr_isr_stall_host2soc_3(), compile ELPG function calls
  with CONFIG_NVGPU_POWER_PG.
- In ga10b_pmu_handle_swgen1_irq(), move whole function body under
  CONFIG_NVGPU_FALCON_DEBUG to fix unused variable compilation errors.
- Add below TU104 specific files in safety build since some of the code
  in those files is required for GA10B. Unnecessary code will be
  compiled out later on.
	hal/gr/init/gr_init_tu104.c
	hal/class/class_tu104.c
	hal/mc/mc_tu104.c
	hal/fifo/usermode_tu104.c
	hal/gr/falcon/gr_falcon_tu104.c
- Compile out GA10B specific debugger/profiler related files from
  safety build.
- Disable CONFIG_NVGPU_FALCON_DEBUG from safety debug build temporarily
  to work around compilation errors seen with keeping this config
  enabled. Config will be re-enabled in safety debug build later.

e0db40c3a5 gpu: nvgpu: support SW methods in safety temporarily
Removing SW methods completely requires CUDA changes in perforce.
Because of stage-main and module codelines infrastructure this cannot be
done in single series. Hence keep alive couple of SW methods for CUDA
compatibility until SW methods are removed from CUDA code. SW methods
do not perform any action.

Next steps are for CUDA to stop using SW methods. Once that is
integrated this patch can be reverted to completely remove SW method
support in safety build.

d1f3f81553 gpu: nvgpu: remove SW methods from safety build
Improved SDL heartbeat mechanism detects the interrupts triggered by
SW method and treats them as errors. Hence remove the SW method support
completely from safety build. Registers set by SW methods are now set
by default for all the contexts.

Implement new HAL gops.gr.init.set_default_compute_regs() to set the
registers in patch context. Call this HAL while creating each context.

Update gv11b_gr_intr_handle_sw_method() to treat all compute SW methods
as invalid.

Update unit test test_gr_intr_sw_exceptions() so that it now expects
failure for any method/data.

ECC counter structures are freed without removing the node from the

Update the ecc counter free logic to set them to NULL upon free, to
remove them from stats_list and free them by validation.

Also updated some of the ecc init paths where error was not propa-
gated to callers and full ecc counters deallocation was not done.

Now, calling unit ecc_free from any context (with counters alloc-
ated or not) is harmless as requisite checks are in place.

Currently, the ECC errors go unnoticed. ECC errors in GR are handled
by incrementing the ecc counters and clearing the intr registers. No
action is taken bassed on the ECC counters. The ECC intr prints are
also not printed by default.
Ideally, the ECC errors should trigger recovery if they cross the
error threshold. While we wait for the ideal ECC handling, convert
the conditional ECC prints to error messages.

0526e7eaa9 gpu: nvgpu: Create CIC-mon and CIC-rm subunits
common.cic unit is divided into common.cic.mon and common.cic.rm
based on rm and mon process split.

CIC-mon subunit includes the code which is utilized in critical
interrupt handling path like initialization, error detection and
error reporting path. CIC-rm subunit includes the code corresponding
to rest of interrupt handling(like collecting error debug data from
registers) and ISR status management (status of deferred interrupts).

Split the CIC APIs and data-members into above two subunits.

8ccf9820ba gpu: nvgpu: check for valid sm_id in nvgpu_gr_config_get_sm_info
Check if requested sm_id is valid in nvgpu_gr_config_get_sm_info()
function. Also update doxygen documentation for same.

Also, ensure SM count is set using nvgpu_gr_config_set_sm_info() before
usig nvgpu_gr_config_get_sm_info() to retrieve it.

Update unit test test_gr_config_set_get to set valid SM count instead of
random number. With random number it is possible that SM count is set
higher than size of SM info struct. This could result into test process
crash.

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()

   "switch (offset << 2)"

Fix by adding break and default statements to switch case in
