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/tests/drm_buddy: Add tests for allocations exceeding max_order

2026-01-21T05:36:05Z

Add kunit tests that exercise edge cases where allocation requests exceed mm->max_order after rounding. This can happen with non-power-of-two VRAM sizes when the allocator rounds up requests. For example, with 10G VRAM (8G + 2G roots), mm->max_order represents the 8G block. A 9G allocation can round up to 16G in multiple ways: CONTIGUOUS allocation rounds to next power-of-two, or non-CONTIGUOUS with 8G min_block_size rounds to next alignment boundary. The test validates CONTIGUOUS and RANGE flag combinations, ensuring that only CONTIGUOUS-alone allocations use try_harder fallback, while other combinations return -EINVAL when rounded size exceeds memory, preventing BUG_ON assertions.

drm/tests: hdmi: fix build failure

2026-01-20T08:59:37Z

The commit ca59e33f5a1f ("drm/atomic: add max_size check to drm_property_replace_blob_from_id()") added a new parameter to drm_property_replace_blob_from_id(), however commit 7436a87db99d ("drm/tests: hdmi: check the infoframes behaviour") was based on the older tree and used the old number of params (with me failing to run kunit tests when applying). Fix the build error by specifying -1 as the max_size (as expected).

drm/display: hdmi_state_helper: split InfoFrame functions per type

2026-01-19T11:11:46Z

Havign a single set of InfoFrame callbacks doesn't provide enough information to the DRM framework about the InfoFrame types that are actually supported. Also it's not really future-proof: it provides a way to program only a single Vendor-Specific frame, however we might need to support multiple VSIs at the same time (e.g. HDMI vs HDMI Forum VSIs). Provide separate sets of callbacks, one per the InfoFrame type.

drm/connector: make clear_infoframe callback mandatory for HDMI connectors

2026-01-19T11:10:35Z

We already require both hdmi_write_infoframe and hdmi_clear_infoframe for bridges implementing DRM_BRIDGE_OP_HDMI. It makes sense to require the clear_infoframes callback for HDMI connectors utilizing drmm_connector_hdmi_init().

drm/tests: hdmi: check the infoframes behaviour

2026-01-19T11:10:35Z

Verify the InfoFrames behaviour. Check that reporting InfoFrame as unsupported doesn't result in a commit error. Also check that HDR and Audio InfoFrames are not triggered if corresponding features are not enabled.
