Yes, it sounds like a bug. It should take the mutex locally. From: amd-gfx [mailto:amd-gfx-bounces@xxxxxxxxxxxxxxxxxxxxx] On Behalf Of StDenis, Tom Sent: Thursday, August 11, 2016 9:42 AM To: amd-gfx list Subject: GRBM lock in vce_v3_0_check_soft_reset(void *handle) I'm working on tidying up vce v3 and came across the function static int vce_v3_0_check_soft_reset(void *handle) Which writes to the GRBM_GFX_INDEX but doesn't take the mutex around it. Nor does the parent function in amdgpu_device.c which calls all of the check_soft_reset callbacks. Is this a bug? Tom -------------- next part -------------- An HTML attachment was scrubbed...
