Intel Alder Lake S Enablement Code Sent In To DRM-Next For Linux 5.13
A big batch of Intel kernel graphics driver code was sent in as a pull request on Tuesday for DRM-Next ahead of the Linux 5.13 merge window, which should be opening around the end of April and then releasing as stable this summer. Like clockwork with Intel being well known for their timely Linux hardware support, Alder Lake S graphics support headlines this pull.
With building off the existing and mature Gen12 Xe graphics code path, the Alder Lake S enablement isn't all that big but still significant. This Alder Lake S graphics enabling goes along with a lot of other Alder Lake enablement that has been happening in the kernel from sound support to other device enablement.
In recent days Intel also sent out Alder Lake P driver support but that is not part of Tuesday's merge request. But given Intel's longstanding history of timely open-source support, all this Alder Lake support should be squared away in time for these hybrid CPUs/SoCs appearing around the end of 2021 or early 2022.
Besides Alder Lake S enabling, the drm-intel-next-2021-03-16 pull also has improvements to the display code, more Gen9 and Tiger Lake PCH combinations enabled, eDP MSO, and a variety of other mostly display improvements/fixes. The eDP MSO is Multi-SST Operation and is for splitting the panel into two or four horizontal segments.
This latest batch of Intel kernel graphics driver material for Linux 5.13 can be found on dri-devel.
