1528170f1c gpu: nvgpu: ga10b: update pri_hub and ptimer error handling
Replace ga10b_ptimer_isr with gk20a_ptimer_isr.

Remove GPU_PRI_ACCESS_VIOLATION reporting from gp10b hal as only
ga10b should be reporting these errors.

GPU_PRI_TIMEOUT_ERROR was only reported from ptimer ISR. However,
it is to be reported when error code is 0xbadf10xx that can be
seen through priv_ring ISR as well. Hence report this error
from ga10b_priv_ring_decode_error_code called from both bus
and priv_ring isr.

For other error cases GPU_PRI_ACCESS_VIOLATION is reported.

Other updates for priv_ring error handling are given below:

1. Add extra info decode functions for error codes:
 - 0xbad001xx, 0xbad002xx, 0xbad0daxx - decode_host_pri_error
 - 0xbadf13xx - decode_fecs_floorsweep_error
 - 0xbadf24xx, 0xbadf25xx, 0xbadf26xx - decode_gcgpc_error &
					decode_pri_local_decode_error
 - 0xbadf20xx, 0xbadf22xx - decode_fecs_pri_orphan_error
 - 0xbadf52xx - decode_pri_indirect_access_violation
 - 0xbadf60xx - decode_pri_lock_sec_sensor_violation

2. Add more info prints to decode_pri_falcom_mem_violation.

3. Add entry for extra info corresponding to 0x41 to
pri_client_error_extra_4x.

4. Separate extra info decode function for error 0xbadf50xx.

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.

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.

With this change, stall and nonstall interrupt for units are programmed
at MC level along with individual unit interrupts. Kept access to MC
interrupt registers through mc.intr_lock spinlock.

For doing this separated CE and GR interrupt mask functions.
mc.intr_enable is only used when there is global interrupt
control to be set. Removed mc_gp10b.c as mc_gp10b_intr_enable
is now removed. Removed following functions - mc_gv100_intr_enable,
mc_gv11b_intr_enable & intr_tu104_enable. Removed intr_pmu_unit_config
as we can use the generic unit interrupt control function.

69ef86e627 gpu: nvgpu: move safe code HAL files to fusa
This patch moves all the safe static and non-static functions as well
as its dependencies such as static declared structs into files with
_fusa.c extension. If the original file is left with no functions
remaining then the file is deleted.

Added changes in Makefile, Makefile.sources, nvgpu-hal-new.yaml for
compilation.
