From 6fe52b63f569c11a70b737751055afd46c4454b3 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Andr=C3=A9=20Almeida?= Date: Tue, 4 Feb 2025 12:35:28 +0530 Subject: [PATCH 1995/5403] drm/amdgpu: Use device wedged event MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Use DRM's device wedged event to notify userspace that a reset had happened. For now, only use `none` method meant for telemetry capture. In the future we might want to report a recovery method if the reset didn't succeed.
