a. LAUNCH_ERR
- Userspace error.
- Triggered due to faulty launch.
- Handle using recovery to reset CE engine and teardown the
faulty channel.
b. An INVALID_CONFIG -
- Triggered when LCE is mapped to floorswept PCE.
- On iGPU, we use the default PCE 2 LCE HW mapping.
The default mapping can be read from NV_CE_PCE2LCE_CONFIG
INIT value in CE refmanual.
- NvGPU driver configures the mapping on dGPUs (currently only on
Turing).
- So, this interrupt can only be triggered if there is
kernel or HW error
- Recovery ( which is killing the context + engine reset) will
not help resolve this error.
- Trigger Quiesce as part of handling.
c. A MTHD_BUFFER_FAULT -
- NvGPU driver allocates fault buffers for all TSGs or contexts,
maps them in BAR2 VA space and writes the VA into channel
instance block.
- Can be triggered only due to kernel bug
- Recovery will not help, need quiesce
d. FBUF_CRC_FAIL
- Triggered when the CRC entry read from the method fault buffer
does not match the computed CRC from the methods contained in
the buffer.
- This indicates memory corruption and is a fatal interrupt which
at least requires the LCE to be reset before operations can
start again, if not the entire GPU.
- Better to quiesce on memory corruption
CE Engine reset (via recovery) will not help.
e. FBUF_MAGIC_CHK_FAIL
- Triggered when the MAGIC_NUM entry read from the method fault
buf does not match NV_CE_MTHD_BUFFER_GLOBAL_HDR_MAGIC_NUM_VAL
- This indicates memory corruption and is a fatal interrupt
- Better to quiesce on memory corruption

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.

Create device nodes for user-created scheduling domains. This helps
leverage filesystem based access control: domains can be chosen to be
available for a limited set of users on a system.
The device nodes are dynamic: they can be removed while the driver is
running normally. This is a bit different from the nodes that exist
until the driver is unloaded, so the devno/domain mapping is stored in a
separate list. The usual container_of pattern would suffer from an
unavoidable race condition if a domain file was opened while the same
domain would get removed.
As usual, domain refcounting prevents a domain from being removed. Now
the open device files hold refs and thus any open domain files prevent a
domain from getting removed, in addition to the userspace-invisible ref
that is taken when a TSG is bound to a domain.
While at it, make the query ioctl guarded by the sched domain mutex, as
domains might technically get added or removed during the querying code.

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.

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

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.

- implemented device info cmd to send device info to the gsp for
runlist submission. Currently GSP scheduler support only GR
engine '0' instance.
- implemented runlist submit cmd. GSP firmware will submit the
corresponding runlist by writing into submit registers. This
command is direct replacement of hw_submit ga10b hal for GR engine.

- NVGPU need to check for priv lockdown release before configuring
any priv registers. In current GSP bootstrap sequence has irq
configuration after GSP engine reset which is causing priv errors.
So irq configuration should be done after GSP firmware releases
priv lockdown.
- Removed clearing irq mask and dest registers before configuring
them as GSP firmware would have done partial irq configuration
before releasing the priv.
