From 201ccbfa8503daee9562a22f50a5b626fe4cc6a1 Mon Sep 17 00:00:00 2001 From: seshendra Gadagottu Date: Mon, 16 Oct 2017 12:14:29 -0700 Subject: gpu: nvgpu: gv11b: update dbg ops Updated following hal functions for gv11b and reused them for gv100: perfbuffer_enable perfbuffer_disable These changes are needed because of following reasons: 1. Register offsets for perf_pmasys_* are changed for gv11b/gv100 from gk20a. 2. Updated memory type for perf_pmasys_mem_block_target to sys_ncoh_f().
