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/display: hdmi_state_helper: split InfoFrame functions per type

2026-01-19T11:11:46+00:00

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/sun4i: Nuke mixer pointer from layer code

It's not used anymore, so remove it. This allows trully independent layer state from mixer. Reviewed-by: Chen-Yu Tsai Tested-by: Ryan Walklin Signed-off-by: Jernej Skrabec Link: https://patch.msgid.link/20251104180942.61538-31-jernej.skrabec@gmail.com Signed-off-by: Chen-Yu Tsai

drm/sun4i: vi_scaler: Find mixer from crtc

2025-11-12T09:18:25+00:00

With "floating" planes in DE33, mixer can't be stored in layer structure anymore. Find mixer using currently bound crtc.

Later special plane only driver for DE33 will provide separate configuration. This change will also help layer driver migrate away from mixer structure.

drm/sun4i: mixer: Add quirk for number of VI scalers

2025-11-12T09:18:25+00:00

On DE2 and DE3, UI scalers are located right after VI scalers. So in order to calculate proper UI scaler base address, number of VI scalers must be known. In practice, it is same as number of VI channels, but it doesn't need to be. Let's make a quirk for this number. Code for configuring channels and associated functions won't have access to vi_num quirk anymore after rework for independent planes.

They can't be triggered if mixer configuration is properly specified in quirks. Additionally, number of VI channels won't be available in future due to rework for DE33 support.
