Subject: [PATCH -next v2 0/2] drm: verisilicon: add hardware cursor support
Date: Tue, 24 Mar 2026 14:02:20 +0800 [thread overview]
Message-ID: <20260324060222.2029061-1-zhengxingda@iscas.ac.cn> (raw)
Verisilicon display controllers have the hardware cursor feature.
The hardware cursor layer is a simplistic and restrictive layer as the
topmost layer of the display output. It can only support ARGB8888 images
and some certain square power-of-two sizes (32x32 is supported on all
DCs).
This patchset adds support for the hardware cursor as a cursor plane.
