Subject: [PATCH 2/2] drm/amdkfd: Make KFD support on Hawaii experimental
Date: Wed, 8 Dec 2021 03:25:31 -0500	[thread overview]
Message-ID: <20211208082531.918062-2-Felix.Kuehling@amd.com> (raw)
In-Reply-To: <20211208082531.918062-1-Felix.Kuehling@amd.com>

Hawaii support is mostly untested these days. ROCm user mode also
depends on custom firmware for AQL packet processing, that was never
pushed upstream due to quality regressions in graphics driver testing.
