benjamin545: there is probably no matching pixel format, consider using glimagesink (hense the GPU) to render, it *should* also work headless
<ndufresne>
That being said, perhaps try again with force-modesettig=1 on kmssink, perhaps primary plane do nv12
<benjamin545>
yes, i had seen you can specify the plane with kmssink, and with modetest i could see the planes, 34 and 37. if i specify the plane 34, looks like the normally used plane, it renders but its slow because it doesnt support NV12, the other plane supports only NV12, but when selected gst-launch doesn't want to run, it looks like its not attached to display

Hi
<hipboi>
We plan to donate some Radxa Zero to developers with mainline support

@narmstrong I have some questions about the mainline u-boot, it seems currently the dram timing is not passed to the amlogic ddr.fw?

thank you ndufresne, glimagesink works. i can play h264 1080 hdr content at high bitrates. im running into an issue with 4k content, playback is choppy, i suspect there could be a memory bandwidth issue? the gpu has to access and color convert all that data.

benjamin545: for non sloppy 4k, avoiding gl is necessary and import directly into the DRM video plane, but this ain't easy
<narmstrong>
hipboi: no idea, ddr setup is done in the binary ATF provided by amlogic by loading the config data in from the acs.bin generated from the vendor u-boot tree
<narmstrong>
hipboi: there is no link with mainline u-boot, mainline u-boot only gets the reserved memory zones and the DDR size from registers filled by the amlogic binaries

Ok, great. Now my N2 is dying after 15 minutes or so.
<alyssa>
As in, all SSH freezes, all the LEDs on the board go out, have to unplug and replug the power for it to come back.
<alyssa>
I can't.

Smells like kernel but ugh

narmstrong: Please tell me there's a patch I can cherrypick 🙁 ^

Is importing directly to the video layer an issue in general with v4l2 m2m drivers or is this something specific to amlogic right now?

Gpu is not powerful enough and ddr bandwidth is too limited
