From a37cec19f0cf5212cbd472cd8d94acaa1e1cff6d Mon Sep 17 00:00:00 2001 From: Aparna Das Date: Mon, 30 Oct 2017 15:55:11 -0700 Subject: gpu: nvgpu: vgpu: modify tsg enable sequence TSG enable sequence in native has been modified due to a hardware bug requiring enabling all channels with NEXT and CTX_RELOAD set in a TSG, and then enabling rest of channels. However it is not possible to check if NEXT and CTX_RELOAD is set in vgpu. Have a separate implementation for enabling tsg sequence in vgpu till the fix for hardware bug is implemented for virtualized configuration.
