From 5cb995c7510e0290956a3aa221c6a77d4020b3ff Mon Sep 17 00:00:00 2001 From: Ashutosh Jain Date: Wed, 20 Jan 2016 20:06:23 +0530 Subject: gpu: nvgpu: Fix wait for sm lock down. global_esr and warp_esr are edge-triggered and are cleared in kernel isr so skip checking them when wait_for_pause is called from UMD via ioctl.
