From e0dbf3a784f6cb1a6e1c41a23123b19ec73b8708 Mon Sep 17 00:00:00 2001 From: Deepak Goyal Date: Thu, 18 Jan 2018 11:44:47 +0530 Subject: gpu: nvgpu: gv11b: Enable perfmon. t19x PMU ucode uses RPC mechanism for PERFMON commands. - Declared "pmu_init_perfmon", "pmu_perfmon_start_sampling", "pmu_perfmon_stop_sampling" and "pmu_perfmon_get_samples" in pmu ops to differenciate for chips using RPC & legacy cmd/msg mechanism. - Defined and used PERFMON RPC commands for t19x - INIT - START - STOP - QUERY - Adds RPC handler for PERFMON RPC commands. - For guerying GPU utilization/load, we need to send PERFMON_QUERY RPC command for gv11b. - Enables perfmon for gv11b.
