This Raspberry Pi 4 It has been the main topic of many electronics enthusiasts and many software developers who love the platform. Raspberry Pi 4 introduces two micro HDMI ports, one port provides 4k 60 Hz, and two ports provide up to 4k 30 Hz.According to the latest round of patches submitted by Maxime Ripard, we will soon receive improved support 4K 60 Hz resolution Use Broadcom VC4 processor and HDMI.
According to the original text Phoenix Report, Broadcom VC4 kernel direct rendering manager (DRM) has seen the main work to support 4K resolution at 60 Hz refresh rate.
Broadcom VC4 is the fourth iteration of Broadcom Video core Low-power mobile multimedia accelerator. It is essentially a series of graphics cards designed for low-power devices.
Maxime Ripard, a developer trying to provide support for the Linux kernel, has modified the DRM of VC4 for the seventh time and submitted the changes to the public Linux repository. Since the deadline for this version of DRM has ended, it is unlikely to support the upcoming Linux kernel version 5.15. However, we can see it in the upcoming kernel revision.
The important thing to note is that the 4K 60 Hz support of VC4 is only available for the Raspberry Pi 4 module with BCM2711 SoC and the HDMI port on the updated version of the Raspberry Pi platform.
