Date: Wed, 4 Dec 2024 14:44:00 +0100 Message-ID: <20241204134410.1161769-1-dev@lankhorst.se> X-Mailer: git-send-email 2.43.0 Precedence: bulk X-Mailing-List: linux-kernel@vger.kernel.org List-Id: List-Subscribe: List-Unsubscribe: MIME-Version: 1.0 Content-Transfer-Encoding: 8bit New update. Instead of calling it the 'dev' cgroup, it's now the 'dmem' cgroup. Because it only deals with memory regions, the UAPI has been updated to use dmem.min/low/max/current, and to make the API cleaner, the names are changed too. dmem.current could contain a line like: "drm/0000:03:00.0/vram0 1073741824" But I think using "drm/card0/vram0" instead of PCIID would perhaps be good too. I'm open to changing it to that based on feedback. I've created an IGT test for min and max, and found the changes from Friedrich Vock sent as feedback were needed. I've integrated those into the first patch.
