drm: Fix use-after-free on framebuffers and property blobs when calling drm_dev_unplug

2026-03-25T10:13:20+00:00

commit 6bee098b91417654703e17eb5c1822c6dfd0c01d upstream. When trying to do a rather aggressive test of igt's "xe_module_load --r reload" with a full desktop environment and game running I noticed a few OOPSes when dereferencing freed pointers, related to framebuffers and property blobs after the compositor exits. Solve this by guarding the freeing in drm_file with drm_dev_enter/exit, and immediately put the references from struct drm_file objects during drm_dev_unplug(). Related warnings for framebuffers on the subtest: [ 739.713076] ------------[ cut here ]------------ WARN_ON(!list_empty(&dev->mode_config.fb_list)) [ 739.713079] WARNING: drivers/gpu/drm/drm_mode_config.c:584 at drm_mode_config_cleanup+0x30b/0x320 [drm], CPU#12: xe_module_load/13145 ....

drm/client: Pass force parameter to client restore

2025-11-25T07:43:46+00:00

Add force parameter to client restore and pass value through the layers. The only currently used value is false. If force is true, the client should restore its display even if it does not hold the DRM master lock. This is be required for emergency output, such as sysrq. While at it, inline drm_fb_helper_lastclose(), which is a trivial wrapper around drm_fb_helper_restore_fbdev_mode_unlocked().

drm: add debugfs support on per client-id basis

2025-07-04T13:59:06+00:00

add support to add a directory for each client-id with root at the dri level. Since the clients are unique and not just related to one single drm device, so it makes more sense to add all the client based nodes with root as dri. Also create a debugfs file which show the process information for the client and create a symlink back to the parent drm device from each client.

drm/fdinfo: Protect against driver unbind

2025-04-28T18:04:15+00:00

If we unbind a driver from the PCI device with an active DRM client, subsequent read of the fdinfo data associated with the file descriptor in question will not end well. Protect the path with a drm_dev_enter/exit() pair.

drm/file: Add fdinfo helper for printing regions with prefix

2025-02-07T14:23:36+00:00

This is motivated by the desire of some drivers (eg. Panthor) to print the size of internal memory regions with a prefix that reflects the driver name, as suggested in the previous documentation commit. That means adding a new argument to print_size and making it available for DRM users.

drm: make drm-active- stats optional

2024-12-19T15:56:17+00:00

When memory stats is generated fresh everytime by going though all the BOs, their active information is quite easy to get. But if the stats are tracked with BO's state this becomes harder since the job scheduling part doesn't really deal with individual buffers. Make drm-active- optional to enable amdgpu to switch to the second method.
