From 7af9b47471e5201a8cd8e027c18955640fca0065 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ma=C3=ADra=20Canal?= Date: Tue, 25 Jul 2023 08:04:20 -0300 Subject: [PATCH] drm-uapi: extend interface for reset timestamp CPU job MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Extend the UAPI to support the reset timestamp user extension for the CPU job. This user extension will allow the creation of a CPU job that resets a timestamp query by updating the timestamp BO and reseting the timestamp's availability syncobj.
