01dccf163d gpu: nvgpu: add logic for index conversion of GPCs/FBPs
For SMC mode, userspace is expected to use local indexing
for accessing GPC/FBP specific perf registers where local indexing
refers to indexes localized to a given SMC instance. H/W however expects
logical id based indexing for these registers. Currently, nvgpu driver maintains
a mapping between local <-> logical/physical ids of the GPCs for SMC specific
configurations/instances.

These register accesses are performed by the Debugger/Profiler interfaces and uses regops
for read/writes. In their current state, regops simply validates register addresses and performs
the required operation on them. These registers are currently indexed using local ids
and there is a need to convert them to use logical ids for supporting SMC modes. For non-SMC case
local ids are equivalent to logical ids and hence the conversion would have no effect on them.

Following changes are added to facilitate the above conversion from
local ids to logical ids in the regops path.

1) nvgpu_profiler_allowlist_range_search is modified to update
a nvgpu_pm_resource_register_range_map entry instead of just the
type.

2) added two APIs, one meant for profiler V2 based interfaces
and the other for legacy profiler interface. The logic for
legacy profiler interface extends into the more generic profiler
V2 logic to help retain future compatibility. These APIs are added
just after the validation stage for nvgpu_exec_regops.

3) The above APIs return an error if the local ids exceed the number
of GPCs/FBPs for a particular instance.

3e4fb49270 gpu: nvgpu: Exit early on VAB_ERROR MMU fault
This patch updates the interaction between the VAB
packet polling code and the VAB_ERROR MMU fault handling
code. A shared atomic flag is used to determine if a
VAB_ERROR MMU fault has happened while polling, which will
result in polling be terminated immediately instead of
waiting on a timeout to happen. This allows testing VAB_ERROR
MMU fault handling in environments where a timeout may never
happen or happen very slowly.

The sequence for this to work is the following:
1) before requesting a VAB dump, which may trigger a fault,
   the atomic flag is atomically reset to 0.
2) polling eventually starts which atomically checks the flag
   in the loop. If flag is set, polling exits because the VAB
   result will never be available.
3) If a VAB_ERROR MMU fault is raised, this sets the flag to 1
   atomically.

Note that while there could be a race in this sequence if the
VAB_ERROR MMU fault handling is somehow delayed, the chance is
extremely slim because:
1) the race could only happen if the VAB dump code is re-entered
   before the earlier VAB_ERROR MMU fault is still pending.
2) the polling code has a large timeout
3) re-entering means a new ioctl/devctl

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.

This now occurs from _PAGESIZE_ flags which are required by

8736c0d467 gpu: nvgpu: add and use sw-only timers
The nvgpu timeout API has an internal override for presilicon mode by
default: in presi simulation environments the timeouts never trigger.
This behaviour is intended in the original usecase of the timer unit
with hardware polling loops. In pure software logic though, the timer
must trigger after the specified timeout even in presi mode so add a new
init function to produce a timer for software logic. Use this new kind
of timer in channel and scheduling worker threads.

The channel worker currently times out for just the purpose of the
channel watchdog timer which has its own internal timer. Although that's
just software, the general expectation is that the watchdog does not
trigger in presilicon tests that run slower than usual. The internal
watchdog timer thus keeps the non-sw mode.

40397ac0c4 gpu: nvgpu: update CBC init sequence
At present, for each resume cycle the driver sends the
"nvgpu_cbc_op_clear" command to L2 cache controller, this causes the
contents of the compression bit backing store to be cleared, and results
in corrupting the metadata for all the compressible surfaces already allocated.
Fix this by updating cbc.init function to be aware of resume state and
not clear the compression bit backing store, instead issue
"nvgpu_cbc_op_invalide" command, this should leave the backing store in a
consistent state across suspend/resume cycles.

The updated cbc.init HAL for gv11b is reusable acrosss multiple chips, hence
remove unnecessary chip specific cbc.init HALs.

535a27411a gpu: nvgpu: fix allocator debugfs deinit
Allocator (bitmap, buddy, page) debugfs files are not cleaned up when
the allocators are destroyed. This leads to warning logs from nvgpu
like below:

[21073.493000] debugfs: File 'gk20a_as_17' in directory 'allocators' already present!
[21073.493026] debugfs: File 'gk20a_as_17-sys' in directory 'allocators' already present!

Remove the per-allocator debugfs node when destroying an allocator in
runtime.

While at this, add missing nvgpu_allocator locking to the function
nvgpu_bitmap_alloc_destroy. And create nop functions for the
functions nvgpu_init_alloc_debug and nvgpu_fini_alloc_debug
when CONFIG_DEBUG_FS is not defined to avoid adding the
CONFIG checks at multiple places.

Move gk20a_debug_deinit to the end of gk20a_free_cb called in nvgpu_put
as that tears down all debugfs entries. Allocator destroy happens as
part of nvgpu_put call and it can lead to invalid debugfs dentry
access if gk20a_debug_deinit is called before it.

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.

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.

ae166bba8a gpu: nvgpu: posix: print WARN*() location
WARN() and WARN_ON() are most useful when the log explains where they
happened. The posix implementation of these prints neither that nor the
warning message (if any). Extend the macros to include function name and
line number, and print those plus the format string.

Actually formatting the format string is problematic wrt. MISRA rules,
so the arguments are not formatted.

The implementation of BUG() already prints the function name and line
number.

632644b44a gpu: nvgpu: couple runlist domains and nvs
Now that the main nvsched code exists in the nvgpu build, make it
control the runlist domains. As a new nvs domain is created, create the
relevant runlist data too. To support the default domain, create a
default nvs domain at boot.

The scheduling domain code owns the responsibility of domain lifetime,
and runlist domains exist to serve that logic although the RL domains
are directly used by channel and TSG logic. Add refcounting to the
scheduler uapi level to make sure that busy domains (that still have TSG
participants) do not get removed too early.

Adjust error injection sensitive unit tests to match the updated logic.
