From c6eabbab359c156669e10d5dec3e71e80ff09bd2 Mon Sep 17 00:00:00 2001 From: Christian Gmeiner Date: Mon, 2 Dec 2024 15:06:13 +0100 Subject: drm/v3d: Add DRM_IOCTL_V3D_PERFMON_SET_GLOBAL MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a new ioctl, DRM_IOCTL_V3D_PERFMON_SET_GLOBAL, to allow configuration of a global performance monitor (perfmon). Use the global perfmon for all jobs to ensure consistent performance tracking across submissions. This feature is needed to implement a Perfetto datasources in user-space.
