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.
