Edit Reason: added Lima, misc
)
Or ultimately Vulkan. I've been going in circles for a week or so between my Rock64 and my Odroid N2 trying to get the Malis to do anything remotely like acceleration or being controlled by a language like OpenGL ES or Vulkan, under X11 anyway. ARM/Mali only supports Wayland (and Android) at least from some point on. Panfrost is supposed to work with the older 2Mali families, not Bifrost but Utgard and Midgard.
So Panfrost https://panfrost.freedesktop.org/ attempts to change that. I have Panfrost installed on my Rock64 but there's one catch:
If I run es2gears it runs at about 200 FPS but it's also using 120% of the CPU because it's doing software emulation instead of using the Mali. When I first got this Rock64 about a year ago I thought es2gears ran at about 600 FPS. Then something broke, it sat for 6 months, I reloaded with Ayufan's Buster image, and now it's slow. The kernel part of a Mali driver is free and open source https://developer.arm.com/tools-and-soft...ard-kernel I'm not sure if I need to try to get Ayufan's kernel config and set up a kernel or not. I have a /dev/dri and /dev/mali and /dev/fb0.

OK, I just tried Lima too, it's about the same. There are some Mali userspace drivers at https://developer.arm.com/tools-and-soft...user-space but it's hit-or-miss. The Rock64 has a Mali 450mp2 which is an Utgard family so Lima should work. https://gitlab.freedesktop.org/lima
My dmesg shows "mali-utgard" like it's a driver name or something and locate "drivers/gpu/arm" finds
lsmod shows a mali module loaded, I have a /dev/mali, so how come it doesn't work? (or is it?)
When I'm running es2gears lsof doesn't list /dev/mali as being open.
So Panfrost https://panfrost.freedesktop.org/ attempts to change that. I have Panfrost installed on my Rock64 but there's one catch:
Quote:Use a mainline kernel version 5.2 or later with CONFIG_DRM_PANFROST enabled
