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

Revert "drm: Introduce pixel_source DRM plane property"

This reverts commit e50e5fed41c7eed2db4119645bf3480ec43fec11. Although the Solid Fill planes patchset got all reviews and acknowledgements, it doesn't fulfill requirements for the new uABI. It has neither corresponding open-source userspace implementation nor the IGT tests coverage. Reverting this patchset until userspace obligations are fulfilled.

Document and add support for solid_fill property to drm_plane. In addition, add support for setting and getting the values for solid_fill. To enable solid fill planes, userspace must assign a property blob to the "solid_fill" plane property containing the following information: struct drm_mode_solid_fill { u32 r, g, b, pad; }; Acked-by: Harry Wentland Acked-by: Sebastian Wick Signed-off-by: Jessica Zhang Reviewed-by: Dmitry Baryshkov Signed-off-by: Dmitry Baryshkov Link: https://patchwork.freedesktop.org/patch/msgid/20231027-solid-fill-v7-2-780188bfa7b2@quicinc.com
