Linux 5.13 Graphics Drivers Are Exciting From Intel Alder Lake S Bring-Up To AMD FreeSync HDMI

Highlights of the kernel graphics/display driver work for Linux 5.13 includes:
- The Intel driver has added support for Alder Lake S hardware. There is also other next-gen hardware work around DDR5/LPDDR5 and other work.
- Lots of Intel graphics driver churn continues around bringing up DG1 / discrete graphics support into this driver.
- The AMDGPU driver finally has support for HDMI FreeSync support! FreeSync via DisplayPort has been supported by this open-source AMD Radeon driver for years while finally the HDMI code is wired up for the pre-HDMI-2.1 FreeSync spec. HDMI 2.1 Variable Rate Refresh is still blocked in open-source drivers by the HDMI Forum.
- Initial support for the AMD Aldebaran accelerator / CDNA compute card.
- Various AMDGPU power management and display improvements.
- The Freedreno DRM driver has initial support for the Qualcomm SC7280.
- Raspberry Pi 4 CEC support within the VC4 DRM driver for HDMI Consumer Electronic Controls.
- DRM core code has seen work around DisplayID handling.
- The GUD Generic USB display driver was added to make for some innovative use-cases moving forward.
Overall it's quite a lively cycle on the open-source graphics/display driver front between new features and hardware support for yet-to-be-released graphics processors. The full list of DRM feature patches for the Linux 5.13 merge window can be found via this pull request that was already merged to mainline.
