37c6b8b1c3 gpu: nvgpu: update reporting of errors to sdl
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.

0699220b85 gpu: nvgpu: compile-out unused apis from safety build
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.

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.

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.

6fb2b892ce gpu: nvgpu: set/check mmu nack flags only for GPC exceptions
gv11b_mm_mmu_fault_handle_mmu_fault_refch() right now checks/sets
mmu_nack_handled flag for MMU faults from all clients (i.e. GPC/HUB).

Handling of MMU nack in MMU fault handling path is only needed if MMU
nack exception is triggered by SM in GPC. Hence set and check this flag
only if source client is GPC.

In certain cases it is possible that CE engine triggers back to back
MMU faults on same channel. When this happens, and because of above
incorrect mmu_nack_handled flag handling, mmu_nack_handled flag is set
while handling second MMU fault from CE.

And because of this gv11b_mm_mmu_fault_handle_mmu_fault_refch() function
could end up dropping extra channel refcounts and trigger access after
free scenarios on that channel.

096f4ef055 gpu: nvgpu: fix l2_flush errors during rmmod
The function gk20a_mm_l2_flush incorrectly returns an error value
when it skips l2_flush when hardware is powered off.
This causes the following prints to occur even when the behavior is expected.

gv11b_mm_l2_flush:43 [ERR] gk20a_mm_l2_flush failed
nvgpu_gmmu_unmap_locked:1043 [ERR] gk20a_mm_l2_flush[1] failed

The above errors occur from the following paths
1) gk20a_remove -> gk20a_free_cb -> gk20a_remove_support ->
	nvgpu_pmu_remove_support -> nvgpu_pmu_pg_deinit ->
	nvgpu_dma_unmap_free

2) gk20a_remove -> gk20a_free_cb -> gk20a_remove_support ->
	nvgpu_remove_mm_support -> gv11b_mm_mmu_fault_info_mem_destroy ->
        nvgpu_dma_unmap_free

Since, these do not belong in the Poweron/Poweroff path, its okay to
skip flushing them when the hardware has powered off.

Fixed the userspace tests by allocating g->mm.bar1.vm to prevent NULL access
in gv11b_mm_l2_flush->tlb_invalidate.

650ce63466 gpu: nvgpu: make iommu bit getting hal NULL for turing
For dgpu iommu bit is causing smmu fault when sysmem is accessed
via pcie. Since pcie is always having iommu enabled on linux that
creates issue for linux. So don't set the iommu bit for dgpu in any
case.

bbb63c0a8c gpu: nvgpu: remove "trace/events/gk20a.h" from QNX build
- "include/trace/events/gk20a.h" file was having GPL2 license
(which should not used for QNX code). This file was used for
compiling linux userspace driver("libnvgpu-drv.so") and was used for
unit testing on QNX.
- This patch removes stubs in "include/trace/events/gk20a.h" file.
(which were used for linux userspace driver.)
- For QNX driver, "nvgpu_rmos/trace/events/gk20a.h" was used.
This patch moves that file to "include/nvgpu/posix/trace_gk20a.h" and
does relevant license change. This same file will be used for linux
userspace driver.
- This patch also creates a new file "include/nvgpu/trace.h" which
selects proper trace file depending on the config.

name space with overlapping visibility should be typographically
unambiguous.

In both the nvgpu_locate_pte_last_level() and gp10b_get_pde0_pgz()
routines this violation is raised because a variable used as
a for-loop index ('i') is ambiguous with a parameter that points
to a struct gk20a_mmu_level ('l').

To fix these violations the loop index 'i' is renamed to 'idx'.

7a62265dde gpu: nvgpu: enable irqs before nvgpu_finalize_poweron
IRQs were not enabled before nvgpu_finalize_poweron, so debugging early
init issues such as MMU fault, invalid PRIV ring or bus access etc.
triggered during nvgpu power-on was cumbersome. Hence, Enable the
IRQs before nvgpu_finalize_poweron is called.

In HUB (MMU fault) ISR, MMU fault handling is only limited to snapped
in priv reg in case of fault during nvgpu power-on.

In HUB (MMU fault) ISR, access to fault buffers is synchronized as
nvgpu driver reads the fault buffer registers before proceeding
with fault handling. However, additional MMU fault handling
needs to be synchronized with GR/FIFO/quiesce/recovery setup
through nvgpu power-on state.

IRQs can get triggered during nvgpu power-on due to MMU fault, invalid
PRIV ring or bus access etc. Handlers for those IRQs can't access the
full state related to the IRQ unless nvgpu is fully powered on.

In order to let the IRQ handlers know about the nvgpu power-on state
gk20a.power_on_state variable has to be protected through spinlock
to avoid the deadlock due to usage of earlier power_lock mutex.

Further the IRQs need to be disabled on local CPU while updating the
power state variable hence use spin_lock_irqsave and spin_unlock_-
irqrestore APIs for protecting the access.

252ddc4f05 gpu: nvgpu: add coverity whitelisting support
Add macros for whitelisting coverity violations. These macros use pragma
directives. The pragma directives and whitelisting macros are only
enabled when a coverity scan is being run.

The whitelisting macros have been added to a new header called
static_analysis.h. The contents of safe_ops.h (CERT C safe ops) have
been moved into static_analysis.h because this will be the new header
for static analysis related macros/defines/etc.
