drm/sysfb: Fix efidrm error handling and memory type mismatch

2026-03-31T11:04:51+00:00

Fix incorrect error checking and memory type confusion in efidrm_device_create(). devm_memremap() returns error pointers, not NULL, and returns system memory while devm_ioremap() returns I/O memory. The code incorrectly passes system memory to iosys_map_set_vaddr_iomem(). Restructure to handle each memory type separately. Use devm_ioremap*() with ERR_PTR(-ENXIO) for WC/UC, and devm_memremap() with ERR_CAST() for WT/WB.

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/sysfb: Remove duplicate declarations

sysfb: Move edid_info into sysfb_primary_display

2025-12-16T13:12:44+00:00

Move x86's edid_info into sysfb_primary_display as a new field named edid. Adapt all users. An instance of edid_info has only been defined on x86. With the move into sysfb_primary_display, it becomes available on all architectures. Therefore remove this contraint from CONFIG_FIRMWARE_EDID. x86 fills the EDID data from boot_params.edid_info. DRM drivers pick up the raw data and make it available to DRM clients. Replace the drivers' references to edid_info and instead use the sysfb_display_info as passed from sysfb.

drm: include drm_print.h where needed

2025-10-31T08:34:52+00:00

There are a gazillion files that depend on drm_print.h being indirectly included via drm_buddy.h, drm_mm.h, or ttm/ttm_resource.h. In preparation for removing those includes, explicitly include drm_print.h where needed.
