Subject: [PATCH 07/11] drm/amdgpu: add UAPI to query GFX shadow sizes
Date: Mon, 20 Mar 2023 13:38:06 -0400 [thread overview]
Message-ID: <20230320173810.250835-8-alexander.deucher@amd.com> (raw)
In-Reply-To: <20230320173810.250835-1-alexander.deucher@amd.com>
Add UAPI to query the GFX shadow buffer requirements
for preemption on GFX11. UMDs need to specify the shadow
areas for preemption.
