e1cdfaa208 gpu: nvgpu: fix CERT EXP34-C issue
Fix CERT issue in nvgpu_gr_falcon_bind_fecs_elpg where nvgpu_pmu_pg_buf
could return NULL. nvgpu_pmu_pg_buf is called from context where PG
will be enabled hence remove the NULL return logic as it is dead
code.

Replace nvgpu_pmu_pg_buf and nvgpu_pmu_pg_buf_get_cpu_va functions by
new function nvgpu_pmu_pg_buf_alloc.

fb019bf43a gpu: nvgpu: async cmd resp for gv11b
- When DISALLOW cmd is sent from driver to PMU the actual
  completion of the disallow will be acknowledged by PMU
  via a PG EVENT: ASYNC_CMD_RESP.
- Disallow needs a delayed ACK from PMU in order to disable
  the ELPG.
- If ELPG is already engaged, the DISALLOW cmd will trigger
  ELPG exit and then transition to PMU_PG_STATE_DISALLOW.
- After this whole process is completed, PMU will send
  DISALLOW_ACK through ASYNC_CMD_RESP msg.
- After disallow command is sent from the driver, NvGPU driver
  waits/polls for disallow command ack. This is sent immediately
  by msg framework of PMU.
- Then, the driver will poll/wait for ASYNC_CMD_RESP event which
  is the delayed DISALLOW ACK.
- The driver captures the ASYNC_CMD_RESP sent from PMU.
- set disallow_state to ELPG_OFF.
- If the driver does not wait/poll for this delayed disallow
  ack from PMU, it can result in erros  as PMU is still
  processing DISALLOW cmd but the driver progressed further.

6609a05683 gpu: nvgpu: Move ACR WPR init region cmd to LSFM
Move ACR WPR init region cmd from ISR to LSFM as part of LSF bootstrap
request to execute the ACR commands sequentially as well as a blocking
call by polling is_wpr_init_done status till set to true. Needed to
add dealy after each ACR command for ga10b LSPMU due to nvriscv priv
lockdown for ACR commands asynchronously from the nvgpu as detailed
below,

LSPMU engages priv lockdown whenever ACR commands needs to be
processed, and nvgpu polls for interrupt status by polling
pwr_falcon_irqstat_r registers once command is sent to PMU to
process the ACK message from LSPMU if priv lockdown is not
engaged. During NVRISCV priv lockdown couple of register are
not accessible including irqstat register, priv lockdown is
done by LSPMU upon ACR command receive and its asynchronous
to nvgpu which cause nvgpu irqstat read data to be 0xbadf*
during polling at corner cases even though priv lockdown
check is present and interpreting wrongly the irq stat
register.

Add delay of 5ms after ACR command sent to LSPMU(LSPMU takes
~3.5msec to complete the command process) and before polling
the irqstat register in nvgpu to engage priv lockdown in LSPMU.
This additional delay will help to skip reading the irqstat at
corner case during the priv lockdown process.

- 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.

9446cfa320 gpu: nvgpu: update golden image flag for RG seq
The flag pmu->pg->golden_image_initialized is set to
true during initial GPU context creation and is not
cleared while the GPU goes into pm_suspend (during railgate).
Hence, when the GPU resumes after un-railgate it retains
the previous value which can cause ELPG to kick in immediately.
Due to this, when ELPG and Railgating are enabled, IDLE_SNAP
is seen for read access of gr_gpc0_tpc0_sm_arch_r reg.

To resolve this, if golden image is ready set the
pmu->pg->golden_image_initialized to suspend state during railgate,
to delay the early enable of ELPG. Add a new
pmu_init_golden_img_state hal in the NVGPU_INIT_TABLE_ENTRY.
This will be called after all the GR access is done and GPU resumes
completely after un-railgate. This hal will then check if
golden_image_initialized flag is in suspend state, it will set it
to ready state and then re-enable ELPG.

  completion of the disallow will be acknowledged by PMU
  via a new RPC: ASYNC_CMD_RESP.
- Disallow needs a delayed ACK from PMU in order to disable
  the ELPG.
- If ELPG is already engaged, the DISALLOW cmd will trigger
  ELPG exit and then transition to PMU_PG_STATE_DISALLOW.
- After this whole process is completed, PMU will send
  DISALLOW_ACK through ASYNC_CMD_RESP RPC.
- After disallow command is sent from the driver, NvGPU driver
  waits/polls for disallow command ack. This is sent immediately
  by RPC framework of PMU.
- Then, the driver will poll/wait for ASYNC_CMD_RESP event which
  is the delayed DISALLOW ACK.
- The driver captures the ASYNC_CMD_RESP RPC sent from PMU.
- set disallow_state to ELPG_OFF.
- If the driver does not wait/poll for this delayed disallow
  ack from PMU, it can result in pmu halt issues as PMU is still
  processing DISALLOW cmd but the driver progressed further which
  can result in errors.

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.

nvgpu_timeout_init() returns an error code only when the flags parameter
is invalid. There are very few possible values for flags, so extract the
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.

* As of now, working on multiple chip bringup in nvgpu-next repo has
   an issue because we end with losing control on source code (hard to
   find which part of the code belongs to which chip) and it's valuable
   history this affects chip migration on release.

 * To support multiple chip bringup simultaneously, we need new
   guidelines to avoid losing control on source code and make migration
   easier. This change adds links to nvgpu-next repo.

 * Updated return code to ENODEV for consistency
 * Updated ACR unittest to work with ENODEV return code

NOTE:
     These are the initial set of infrastructure changes, guidelines
     will evolve, and source code will get updated accordingly.

     Based on future chip features, Which part of the source code falls
     under nvgpu-next repo is decided.

Enable nvriscv debug buffer feature in NVGPU.
Debug buffer is a feature to print the debug log from ucode onto console
in real time.
Debug buffer feature uses the DMEM, queue and SWGEN1 interrupt to share
ucode debug data with NVGPU.
Ucode writes debug message to DMEM and updates offset in queue to trigger
interrupt to NVGPU.
NVGPU copies the debug message from DMEM to local buffer to process and
print onto console.

Debug buffer feature is added under falcon unit and required engine
can utilize the feature by providing required param through public
functions.

Currently GA10B NVRISCV NS/LS PMU ucode has support for this feature
and enabled support on NVGPU side by adding required changes, with this
feature enabled, it is now possible to see prints in real time.

Replace all nvgpu_next functions/structs either by 1) collapsing them
into nvgpu legacy functions/structs 2) renaming them as follows:
- nvgpu_next_*() => nvgpu_(ga10b/ga100)_*()
- nvgpu_next_*() => (ga10b/ga100)_*()
- nvgpu_next_*() => nvgpu_*() [only if this doesn't cause collision]
- nvgpu_next_*() = > nvgpu_*_extra()

Create hal.sim unit and move Ampere+ SIM code into it.

c7d43f5292 gpu: nvgpu: remove usage of CONFIG_NVGPU_NEXT
The CONFIG_NVGPU_NEXT config is no longer required now that ga10b and
ga100 sources have been collapsed. However, the ga100, ga10b sources
are not safety certified, so mark them as NON_FUSA by replacing
CONFIG_NVGPU_NEXT with CONFIG_NVGPU_NON_FUSA.

Move CONFIG_NVGPU_MIG to Makefile.linux.config and enable MIG support
by default on standard build.

4d3a935b1a gpu: nvgpu: enable lazy bootstrap support for NVRISCV pmu
Lazy bootstrap is a secure iGPU feature where LS falcons(FECS and
GPCCS) are bootstrapped by LSPMU in both cold boot and recovery boot.
As there is no ACR running after boot, we need LSPMU to bootstrap LS
falcons to support recovery.
In absence of LSPMU, ACR will bootstrap LS falcons but recovery is
not supported.
This CL will enable Low secure falcon manager(lsfm) to support
Lazy bootstrap feature. This will allow nvgpu to send cmds
to lspmu to bootstrap LS falcons.
