From 673087d8b023faf34b84e8faf63bbeea3da87bab Mon Sep 17 00:00:00 2001 From: =?utf8?q?Ma=C3=ADra=20Canal?= Date: Sun, 12 May 2024 19:23:29 -0300 Subject: [PATCH] drm/v3d: Deprecate the use of the Performance Counters enum MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The Performance Counters enum used to identify the index of each performance counter and provide the total number of performance counters (V3D_PERFCNT_NUM). But, this enum is only valid for V3D 4.2, not for V3D 7.1. As we implemented a new flexible structure to retrieve performance counters information, we can deprecate this enum.
