[PATCH 2/3] media: qcom: venus: relax encoder frame/blur dimension steps on v4

Renjiang Han
2026-03-31T04:37:44Z

Encoder HFI capabilities on v4 advertise a 16-pixel step for frame and
blur dimensions. This is overly restrictive and can cause userspace caps
negotiation to fail even for valid resolutions.

Relax the advertised step size to 1 and keep alignment enforcement in
buffer layout and size calculations.

Fixes: 8b88cabef404e ("media: venus: hfi_plat_v4: Populate codecs and capabilities for v4")
