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.

a73ca0b70e gpu: nvgpu: split GR ECC initialization
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
acr_construct_execute.

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.

34873d561a gpu: nvgpu: fix bug in fecs method submission
When a method is submitted to the FECS ucode using
gm20b_gr_falcon_submit_fecs_method_op, the status of the operation
is updated in the mailbox register. The driver can choose to skip validation of
the return status by setting op.cond.ok/fail = GR_IS_UCODE_OP_SKIP. At present
the driver continues to check for mailbox status despite the flag being set and
eventually times out.

Update gm20b_gr_falcon_submit_fecs_method_op so that mailbox status check is
skipped if op.cond.ok/fail is set to GR_IS_UCODE_OP_SKIP.
