treewide: Replace kmalloc with kmalloc_obj for non-scalar types

2026-02-21T09:02:28Z

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: include drm_print.h where needed

2025-10-31T08:34:52Z

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.

drm/virtio: Test for imported buffers with drm_gem_is_imported()

2025-04-16T07:05:03Z

Instead of testing import_attach for imported GEM buffers, invoke drm_gem_is_imported() to do the test. The helper tests the dma_buf itself while import_attach is just an artifact of the import. Prepares to make import_attach optional.

drm/virtio: Add drm_panic support

Virtio gpu supports the drm_panic module, which displays a message to the screen when a kernel panic occurs. It is supported where it has vmapped shmem BO.

drm/virtio: Add prepare and cleanup routines for imported dmabuf obj

2024-11-26T10:28:02Z

When an imported dmabuf obj is used as part of an atomic commit, we need to pin it as part of prepare and unpin it during cleanup of the associated FB, to make sure that it does not move until the commit is completed (and also while it is being used on the Host).
