treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28+00:00

This is the result of running the Coccinelle script from scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to avoid scalar types (which need careful case-by-case checking), and instead replace kmalloc-family calls that allocate struct or union object instances: Single allocations: kmalloc(sizeof(TYPE), ...) are replaced with: kmalloc_obj(TYPE, ...) Array allocations: kmalloc_array(COUNT, sizeof(TYPE), ...) are replaced with: kmalloc_objs(TYPE, COUNT, ...) Flex array allocations: kmalloc(struct_size(PTR, FAM, COUNT), ...) are replaced with: kmalloc_flex(*PTR, FAM, COUNT, ...) (where TYPE may also be *VAR) The resulting allocations no longer return "void *", instead returning "TYPE *". Signed-off-by: Kees Cook

drm/log: avoid WARN when searching for usable format

2025-12-19T22:06:41+00:00

Use drm_draw_can_convert_from_xrgb8888() instead of drm_draw_color_from_xrgb8888() while searching for a usable color format. This avoids a WARN in case the first format is not usable.

drm/client: log: Implement struct drm_client_funcs.restore

2025-11-25T07:43:48+00:00

Restore the log client's output when the DRM core invokes the restore callback. Follow the existing behavior of fbdev emulation wrt. the value of the force parameter. If force is false, acquire the DRM master lock and reprogram the display. This is the case when the user-space compositor exits and the DRM core transfers the display back to the in-kernel client. This also enables drm_log output during reboot and shutdown. If force is true, reprogram without considering the master lock. This overrides the current compositor and prints the log to the screen. In case of system malfunction, users can enter SysRq+v to invoke the emergency error reporting. See Documentation/admin-guide/sysrq.rst for more information. v2: - s/exists/exits/ in second paragraph of commit description - fix grammar in commit description Signed-off-by: Thomas Zimmermann Reviewed-by: Jocelyn Falempe Link: https://patch.msgid.link/20251110154616.539328-4-tzimmermann@suse.de

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/client: Create client buffers with drm_client_buffer_create_dumb()

2025-10-30T20:01:35+00:00

Rename drm_client_framebuffer_create() to drm_client_buffer_create_dump() and adapt callers. The new name reflects the function's purpose. Using dumb buffers is the easiest way for creating a GEM buffer in a drivers- independent way. There's also drm_client_buffer_create(), which creates the client buffer from a preexisting buffer object. This helper can be exported for drivers that create their own GEM buffer object.
