Linux 6.2 To Introduce Allwinner A100 & D1 Display Support

Written by Michael Larabel in Linux Kernel on 10 November 2022 at 05:05 AM EST. 2 Comments
Sent out today was this week's batch of "drm-misc-next" code containing Direct Rendering Manager updates to the core infrastructure and smaller drivers of material that is ready for queuing ahead of the Linux 6.2 cycle.

Notable among the smaller display/graphics driver updates this week is the Sun4i DRM/KMS driver for Allwinner SoCs adding support for the A100 and D1 SoCs. The Allwinner A100 is a tablet SoC making use of Arm Cortex-A53 cores. The A100 has an Imagination PowerVR GE8300 GPU while the Sun4i driver is just about handling the display support. The Allwinner D1 meanwhile is notable in being their first RISC-V SoC. Or in particular, the D1-H that has HDMI output support.

Coming by way of drm-misc-next is also a big update to the DRM scheduler code and the AMDGPU integration. The DRM scheduler patches and associated AMDGPU driver patches are there to fix a scheduler hang that can occur when killing a process.

There is also a variety of fixes to the smaller drivers and other improvements as part of this week's drm-misc-next pull request for this feature code that will be found in Linux 6.2.
