drm, drm/xe: Fix xe userptr in the absence of CONFIG_DEVICE_PRIVATE

2026-01-22T09:41:18+00:00

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.

drm/client: Support emergency restore via sysrq for all clients

2025-11-25T07:43:47+00:00

Move the sysrq functionality from DRM fbdev helpers to the DRM device and in-kernel clients, so that it becomes available on all clients. DRM fbdev helpers support emergency restoration of the console output via a special key combination. Press SysRq+v to replace the current compositor with the kernel's output on the framebuffer console. This allows users to see the log messages during system emergencies. By moving the functionality from fbdev helpers to the DRM device, any in-kernel client can serve as emergency output. This can be used to bring up drm_log, for example. Each DRM device registers itself to the list of possible sysrq handlers. On receiving SysRq+v, the DRM core goes over all registered devices and restores an in-kernel DRM client for each of them. See Documentation/admin-guide/sysrq.rst on how to invoke SysRq. Switch VTs to bring back the user-space compositor. v2: - declare placeholders as 'static inline' (kernel test robot) - fix grammar in commit description Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://patch.msgid.link/20251110154616.539328-3-tzimmermann@suse.de

kbuild: Let kernel-doc.py use PYTHON3 override

2025-11-09T02:42:22+00:00

It is possible to force a specific version of python to be used when building the kernel by passing PYTHON3= on the make command line. However kernel-doc.py is currently called with python3 hard-coded and thus ignores this setting. Use $(PYTHON3) to run $(KERNELDOC) so that the desired version of python is used.
