  • HDMI 2.0 support for Tegra

    Unfortunately Nvidia won't be releasing a Ubuntu 20.04 or 22.04 version of Jackpack or L4T for the Jetson Nano so those who want newer software for their Nano are forced to look elsewhere.

    This week I've tried several different builds of Armbian on my Nano but all of them that are using a mainline 5.x kernel produce a flickery and distorted HDMI output under both the fb console and under X. I believe this is because the tegra drm driver doesn't support HDMI 2.0 yet and my display defaults to 4K @ 60 Hz which requires HDMI 2.0 or later.

    Linux 5.16 added open source NVDEC support so I'm keen to test that out but its no use without working HDMI output. Is anybody working on the open source Tegra drm driver?
