From f4b77e465648e87b19a7df4bb2a121ac8ac1b851 Mon Sep 17 00:00:00 2001 From: Thomas Fleury Date: Thu, 16 Jun 2016 17:31:45 -0700 Subject: gpu: nvgpu: process granularity for FECS traces When processing FECS traces, a hash table is used to retrieve the 'pid' of the process that created the channel/TSG. Report process identifer (aka tgid in kernel) instead of thread identifier (aka pid) for FECS traces.
