Good news, thanks for pushing this !

Could you also add the libretech-cc ?

For wayland you should obviously use the wayland one, but this one is buggy, you should take the ARM HiKey binary instead at https://developer.arm.com/-/media/Files/downloads/mali-drivers/user-space/hikey/mali-450_r7p0-01rel0_linux_1arm64.tar.gz?revision=b8764bbe-c4d6-4825-a0d9-bceca4ee4b2d

For video acceleration, Mali is not involved her at all.

No, the armsoc driver doesn't need other x11 driver.
