Subject: [PATCH 1/8] drm/amdkfd: Add gws number to kfd topology node properties
Date: Thu, 23 May 2019 22:41:12 +0000	[thread overview]
Message-ID: <1558651263-3478-1-git-send-email-Oak.Zeng@amd.com> (raw)

Add amdgpu_amdkfd interface to get num_gws and add num_gws
to /sys/class/kfd/kfd/topology/nodes/x/properties. Only report
num_gws if MEC FW support GWS barriers. Currently it is
determined by a module parameter which will be replaced
with MEC FW version check when firmware is ready.
