In Drive 6.0, the error reporting is supported only for orin (ga10b)
in dev-main. For this purpose, this patch does the following:
- Removes the redundant reporting of following IDs from gv11b:
- GPU_HOST_PFIFO_SCHED_ERROR
- GPU_HOST_PFIFO_CTXSW_TIMEOUT_ERROR
- GPU_HOST_PBDMA_HCE_ERROR
- GPU_MMU_L1TLB_SA_DATA_ECC_UNCORRECTED
- GPU_MMU_L1TLB_FA_DATA_ECC_UNCORRECTED
- GPU_LTC_CACHE_DSTG_ECC_CORRECTED
- GPU_LTC_CACHE_TSTG_ECC_UNCORRECTED
- Migrates the reporting of following IDs from gv11b to ga10b:
- GPU_SM_L1_TAG_ECC_CORRECTED
- GPU_SM_L1_TAG_ECC_UNCORRECTED
- GPU_SM_CBU_ECC_UNCORRECTED
- GPU_SM_LRF_ECC_UNCORRECTED
- GPU_SM_L1_DATA_ECC_UNCORRECTED
- GPU_SM_ICACHE_L1_DATA_ECC_UNCORRECTED
- GPU_SM_ICACHE_L0_PREDECODE_ECC_UNCORRECTED
- GPU_SM_L1_TAG_MISS_FIFO_ECC_UNCORRECTED
- GPU_SM_L1_TAG_S2R_PIXPRF_ECC_UNCORRECTED
- Removes the unused ID that doesn't have any HSI related to it:
- GPU_HOST_PBDMA_PREEMPT_ERROR
In addition to the above, this patch does the following:
- Updates error IDs related to page fault error.
- Updates look-up table to remove unused error IDs.

This patch does the following:
- Adds error IDs for GSP ACR and GSP SCHED.
- Updates error IDs for PMU.
- Removes reporting of DMEM ECC_CORRECTED since DMEM RAMs in PWR is
protected only with parity mechanism, (ref: T23x_UPROC_Safety_IAS)
- Removes reporting of IMEM ECC_CORRECTED since IMEM RAMs for PROC in
PWR is protected only with parity mechanism, (ref: T23x_UPROC_Safety_IAS)

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.

Below CE interrupts do not have any users(usecases) on safety build;
disable them only on safety build.
1. BLOCKPIPE stall intr: Not used by GFX(VKSC) and CUDA on safety.
2. NONBLOCK_PIPE nonstall intr: Non-stall intrs are not supported
on safety build. Also, this one is not used by GFX(VKSC)
and CUDA.
3. STALLING_DEBUG intr: Added in Orin tree. It is only needed for
debugging. Disable on safety build as there is no current
usage in driver.
4. POISON_ERROR intr: Poison is a fault containment and not
supported on GA10b.
5. INVALID_CONFIG intr: Floor sweeping not supported on functional

This patch does the following changes:
- 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.

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.

Add a new Central Interrupt Controller(CIC) unit in common code.
The interrupt handling is done in a distributed manner currently.
The error handling policy for different errors resides in each unit's
ISR code. The goal is to converge this data under one central place -
the CIC unit.
This patch creates framework for CIC unit and moves the gv11b QNX
safety LUT to CIC unit. All the error reporting APIs from different
units are also moved to CIC.
New APIs are exposed by CIC unit to access its internal data like:
1. Struct err_desc - the static err handling /injection data per
error id
2. Num_hw_modules - the number of error reporting HW units
supported by CIC
Init and deinit of CIC unit:
1. CIC unit should be initialized earlyon during boot so that it
is available for any interrupt handling.
2. Initialize CIC just before the interrupts are enabled during
boot.
3. Similarly, CIC is disabled late during deinit cycle; right
after the interrupts are masked.
LUT:
1. LUT is currently used only for reporting error to safety
services in gv11b QNX safety build.
2. This error handling policy LUT currently has only two levels
of handing - correctable and quiecse.
3. Once, the error handling policy decision is moved from leaf
unit nodes to CIC, LUT will be updated to have additional levels
like fast recovery and full recovery.
4. Also, then a separate LUT will be added for each platform/build.
5. In current framework, the LUT is set to NULL for all
configurations except gv11b.
report_err() ops is added to report error to safety services.
This ops is only effective for gv11b qnx build; and set to NULL for
other configurations.
