Most notable with the Broadcom VC4 driver work for Linux 6.2 is fixing 4K 60Hz detection for the Raspberry Pi as well as reworking that 4K detection code in general, better core clock calculation, and other increased checks around 4K resolutions. The Broadcom VC4 DRM/KMS driver most notably used by the Raspberry Pi single board computers has received several improvements. Sent out today was the latest batch of drm-misc-next updates targeting the Linux 6.2 kernel and for now being queued into the DRM-Next tree. With the Linux 6.2 cycle in December there are several 4K related improvements to the Raspberry Pi open-source display driver for addressing that prior regression as well as making the 4K monitor handling more robust. But since Linux 5.18 at least some of the 4K handling had regressed for this budget Arm single board computer. Since last year have been patches enabling the Raspberry Pi to output at 4K with a 60Hz refresh rate.
