From ed5915cfce2abb9a553c3737badebd4a11d6c9c7 Mon Sep 17 00:00:00 2001 From: Joonas Lahtinen joonas.lahtinen@linux.intel.com Date: Thu, 22 May 2025 09:41:27 +0300 Subject: [PATCH] Revert "drm/i915/gem: Allow EXEC_CAPTURE on recoverable contexts on DG1" MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit

This reverts commit d6e020819612a4a06207af858e0978be4d3e3140.

The IS_DGFX check was put in place because error capture of buffer objects is expected to be broken on devices with VRAM.

Userspace fix[1] to the impacted media driver has been submitted, merged and a new driver release is out as 25.2.3 where the capture flag is dropped on DG1 thus unblocking the usage of media driver on DG1.
