  3. May I ask how to use panfrost on hdmi display? From what I see, panfrost driver seems supported now with the great work of our developers, but I can't get images on my display with current armbian builds(5.x kernel). I tried orangepi-build to build linux 5.13 kernel, which boots but "modprobe panfrost" doesn't work. Checked the device tree, not gpu sections. Tried also armbian-build, but the config for orange pi zero 2 is still using 4.9 kernel, not including the panfrost driver. At first I thought of using armbian-build with xunlong's config(5.13 kernel), but then I realised it's not possible. Patches are different on both sides. Since there are so many great works done by many great developers, I guess it's possible to use panfrost but I just dont know how. Thank everyone for advising.
