From ae175e45edc5807131dfb1b63d3e4795e96a3f86 Mon Sep 17 00:00:00 2001 From: Divya Singhatwaria Date: Tue, 23 Jul 2019 10:43:35 +0530 Subject: gpu: nvgpu: Use TPC_PG_MASK to powergate the TPC - In GV11B, read fuse_status_opt_tpc_gpc register to read which TPCs are floorswept. - The driver will also read sysfs node: tpc_pg_mask - Based on these two values "can_tpc_powergate" will be set to true or false and mask will be used to write to fuse_ctrl_opt_tpc_gpc register to powergate the TPC. - can_tpc_powergate = true indicates that the mask value sent from userspace is valid and can be used to power gate the desired TPC - can_tpc_powergate = false indicates that the mask value sent from userspace is not valid and cannot be used to power gate the desired TPC.
