From bdcdf968be314b6fc8835b99fb4519e7619671e6 Mon Sep 17 00:00:00 2001 From: Thomas Hellström Date: Wed, 21 Jan 2026 10:10:47 +0100 Subject: drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATE MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit CONFIG_DEVICE_PRIVATE is not selected by default by some distros, for example Fedora, and that leads to a regression in the xe driver since userptr support gets compiled out. It turns out that DRM_GPUSVM, which is needed for xe userptr support compiles also without CONFIG_DEVICE_PRIVATE, but doesn't compile without CONFIG_ZONE_DEVICE. Exclude the drm_pagemap files from compilation with !CONFIG_ZONE_DEVICE, and remove the CONFIG_DEVICE_PRIVATE dependency from CONFIG_DRM_GPUSVM and the xe driver's selection of it, re-enabling xe userptr for those configs. v2: - Don't compile the drm_pagemap files unless CONFIG_ZONE_DEVICE is set. - Adjust the drm_pagemap.h header accordingly.
