This was done entirely with mindless brute force, using git grep -l '\

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: 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.

drm/virtio: Add drm_panic support

2025-02-09T17:36:51+00:00

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: Set missing bo->attached flag

2025-01-09T13:53:19+00:00

VirtIO-GPU driver now supports detachment of shmem BOs from host, but doing it only for imported dma-bufs. Mark all shmem BOs as attached, not just dma-bufs. This is a minor correction since detachment of a non-dmabuf BOs not supported today.

drm/virtio: Implement VIRTIO_GPU_CMD_RESOURCE_DETACH_BACKING cmd

2024-11-26T09:52:18+00:00

This cmd is useful to let the VMM (i.e, Qemu) know that the backing store associated with a resource is no longer valid, so that the VMM can perform any cleanup or unmap operations. The fence related changes and virtio_gpu_object_detach()/ virtio_gpu_detach_object_fenced() routines are extracted from a patch by Dmitry Osipenko .
