Raspberry Pi VC4 DRM To Get Lower Memory/CPU Overhead On Linux 4.9
The latest Raspberry Pi VC4 DRM driver changes have now landed in DRM-Next for in turn landing in the mainline kernel when the Linux 4.9 merge window opens in a few weeks.
The two main feature additions for the VC4 DRM driver are interlaced vblank timing and a memory/CPU overhead reduction when 3D rendering is taking place. The overhead reduction is from not forcing the new binner overflow allocation per-draw. Aside from the VC4 DRM driver work, with Linux 4.9 is where there finally might be mainline support for the Raspberry Pi Zero.
The VC4 pull into DRM-Next can be found here. The Linux 4.9 merge window should be open in early October.
