a765a76c81 gpu:nvgpu: Expose physical gpc,tpc layout for ecc sysfs nodes.
Added new gr_config member to hold TPC physical id map.
Updated ecc stats structures to hold physical gpc,tpc
numbers. Previously logical id's were exposed via ecc
sysfs nodes.
Consumers of ecc sysfs nodes refer tpc_fs_mask which is
physical gpc/tpc layout whereas ecc sysfs nodes were updated
with logical gpc/tpc layout. This change ensures that both
use the same framework.

62d6f753d2 gpu: nvgpu: add support for PES, ROP floorsweeping
Volta+ chips supports PES floorsweeping and Ampere+(iGPU) chips supports
ROP floorsweeping. At present, the driver isn't aware of PES, ROP
floorsweeping, make the driver PES, ROP floorsweeping aware by introducing the
following fields in nvgpu_gr_config:
- gpc_(rop/pes)_mask: Contains the bit mask of non FSed ROP/PES units per GPC.
- gpc_(rop/pes)_logical_id_map: Translates per GPC ROP/PES physical id to
  logical id.

Introduce the following HAL functions to read PES/ROP FS data:
- gops_fuse.fuse_status_opt_(pes/rop)_gpc: This fuction gets the FS
  config from the fuse.
- gops_top.get_max_(pes/rop)_per_gpc: Gets the maximum number of PES/ROP
  units that can be present in a GPC.

In addition, introduce the enabled flag NVGPU_SUPPORT_PES_FS to identify chips
which support PES floorsweeping, piggyback on NVGPU_SUPPORT_ROP_IN_GPC
enabled flag to identify ROP floorsweeping.

3d01b89e68 gpu: nvgpu: expose physical masks for GPCS/FBPs for MIG
Following changes are added
1) nvgpu_gr_config->gpc_tpc_mask_physical is now indexed by physical
gpc id instead of logical id.
2) Removed the conversion of logical fbp ids and replace them with
physical ids.
3) nvgpu_gpu_instance->fbp_en_mask now contains the mask of physical fbp ids.
4) gk20a_ctrl_ioctl_gpu_characteristics returns gpu.gpc_mask returns mask
of physical ids.

f80dccb543 gpu: nvgpu: report gpc_tpc_mask in physical order
At present, there is an inconsistency in the order in which
gpc_tpc masks are reported to the userspace. Both gpc and
tpc masks are reported using physical-ids. However, the
gpc_tpc_masks array is ordered by logical gpc-ids and
not physical-ids. This creates a mismatch between the gpc
reported as enabled in the gpc_mask and its corresponding
gpc_tpc_mask.

Introduce field "gpc_tpc_mask_physical" which stores the
gpc_tpc_masks in physical order and update
NVGPU_GPU_IOCTL_GET_TPC_MASKS to return this field.

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.
