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.
