Talk:Raspberry Pi VC4

''It's also recommended to bump your gpu_mem to 128 (it's what raspi-config does when you enable the driver through it). ''

The vc4 driver uses the kernels contiguous memory allocator for RAM.

When the dtoverlay=vc4-kms-v3d overlay is loaded you get cma=256M@256 added to the kernel command line for free.

Memory allocated to the old graphics driver is wasted, so gpu_mem=16 is a better setting.

"you're almost there"
Section "Is it working?" does not suggest any course of action when llvmpipe is the GL renderer. This is a dead end, at least for me. Grepwood
