4acf78dff3 gpu: nvgpu: guard sync cmd hals properly
Make the syncpt and sema wait and incr command HAL ops consistent. Add
CONFIG_NVGPU_SW_SEMAPHORE guards for the semaphore ops. The syncpoint
ops already have CONFIG_TEGRA_GK20A_NVHOST around them.

Delete the dummy syncpt ops. They are not used; the ops are only needed
when the real versions exist.

6202ead057 gpu: nvgpu: split sema sync hal to wait and incr
Instead of one HAL op with a boolean flag to decide whether to do one
thing or another entirely different thing, use two separate HAL ops for
filling priv cmd bufs with semaphore wait and semaphore increment
commands. It's already two ops for syncpoints, and explicit commands are
more readable than boolean flags.

Change offset into cmdbuf in sem wait HAL to be relative to the cmdbuf,
so the HAL adds the cmdbuf internal offset to it.

While at it, modify the syncpoint cmdbuf HAL ops' prototypes to be
consistent.

9a16bc3fd4 gpu: nvgpu: wait ACK for FECS watchdog timeout
From gv11b onwards, FECS ucode returns an ACK for set watchdog
timeout method. Failure to wait for this ACK was leading to races,
and in some cases, the ACK could be mistaken for the reply to the
next method.

In particular, this happened for the discover golden image size
method which is sent after set watchdog timeout.

With instrumented FECS ucode, it takes longer for the code to
process the set watchdog timeout method, and the write to ack
that method could happen after nvgpu driver clears the mailbox to
send the discover image size method.

With an invalid golden context image size, FECS ended up causing
an MMU fault while attempting to save past allocated buffer.

Added NVGPU_GR_FALCON_METHOD_SET_WATCHDOG_TIMEOUT to be used with
gops_gr_falcon.ctrl_ctxsw, and implemented 2 variants:
- gm20b_gr_falcon_ctrl_ctxsw, without ACK
- gv11b_gr_falcon_ctrl_ctxsw, with ACK

Added NVGPU_GR_FALCON_SUBMIT_METHOD_F_LOCKED flag to allow
executing above method without re-acquiring FECS lock. Longer term,
the 'flags' could be added to gop_gr_falcon.ctrl_ctxsw parameters.

Use gops_gr_falcon.ctrl_ctxsw instead of register writes to invoke
set watchdog timeout method in gm20b_gr_falcon_wait_ctxsw_ready.

Also replaced calls to gm20b_gr_falcon_ctrl_ctxsw to
gops_gr.falcon.ctrl_ctxsw when appropriate, since there are
multiple variants (gm20b, gp10b and gv11b).

Last, fixed clearing of mailbox 0 in gm20b_gr_falcon_bind_instblk.

1c991a58af gpu: nvgpu: Add SM diversity support
To achieve permanent fault coverage, the CTAs launched by
each kernel in the mission and redundant contexts must execute on
different hardware resources. This feature proposes modifications
in the software to modify the virtual SM id to TPC mapping across
the mission and redundant contexts. The virtual SM identifier to TPC
mapping is done by nvgpu when setting up the patch context.

The recommendation for the redundant setting is to offset the
assignment by one TPC, and not by one GPC. This will ensure that both
GPC and TPC diversity. The SM and Quadrant diversity will happen
naturally. For kernels with few CTAs, the diversity is guaranteed
to be 100%. In case of completely random CTA allocation,
e.g. large number of CTAs in the waiting queue, the diversity is
1 - 1/#SM, or 87.5% for GV11B, 97.9% for TU104.

Added NvGpu CFLAGS to enable/disable the SM diversity support
"CONFIG_NVGPU_SM_DIVERSITY".

This support is only enabled on gv11b and tu104 QNX non safety build.

fba516ffae gpu: nvgpu: enable PMU ECC interrupt early
PMU IRQs were not enabled assuming entire functionality for LS PMU.
Debugging early init issues of PMU falcon ECC errors triggered
during nvgpu power-on will be cumbersome if interrupts are not
enabled early. FMEA analysis of the nvgpu init path also
requires this interrupt be enabled earlier.

Hence, Enable the PMU ECC IRQ early during nvgpu_finalize_poweron.
pmu_enable_irq is updated to enable interrupts differently for
safety and non-safety. PMU interrupts disabling is moved out
of nvgpu_pmu_destroy to nvgpu_prepare_poweroff. Prepared new
wrapper API nvgpu_pmu_enable_irq.

PMU ECC init and isr mutex init is moved to the beginning of
nvgpu_pmu_early_init as for safety, ls pmu code path is
disabled. Fixed the pmu_early_init dependent and mc
interrupt related unit tests.

Update the doxygen for changed functions.

Split GR ECC initialization into GPC/TPC and FECS ECC init as FECS ECC
errors during acr_construct_execute need to be reported and handled
hence FECS ECC counters are required to be initialized before

GPC/TPC ECC counters are dependent on the GR config that will be
initialized only after acr_construct_execute.

nvgpu_gr_intr_init_support is moved to nvgpu_gr_prepare_sw.

FECS ECC interrupt is enabled by default hence interrupt is not
enabled through gr_fecs_host_int_enable_r in nvgpu_gr_prepare_sw.
