Mali open source driver #40

Open paju1986 opened 4 years ago

paju1986 commented 4 years ago

how do I enable the Mali open source kernel driver for 3d acceleration?

avafinger commented 4 years ago

lima is the mali open source. Choose the kernel with lima enabled and use Wayland Desktop such as gnome.

Start with this Image: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v2.4

And update the kernel with this: https://github.com/avafinger/bananapi-zero-ubuntu-base-minimal/releases/tag/v3.3

Then install your Gnome (with Wayland), but bear in mind you have 512MB of DRAM, maybe you should adjust CMA=128 (or less) in the boot command. if i remember correctly i had CMA=256 during kernel build. CMA is used by cedrus to do HW decoding.
