Linux DRM: New Picture Processing API

on YouTube ↗46m

" summary

Describes a proposed DRM (Direct Rendering Manager) kernel API extension to expose picture processing hardware—copying, colorspace conversion, scaling, rotation, etc.—through a unified, vendor-neutral interface alongside existing KMS/atomic and universal planes. Focus is on enabling hardware-independent applications on embedded platforms by providing generic access to picture-processing blocks instead of vendor-specific extensions.
