@mntmn - so you're not using textures yet? Mainline should be lacking texture support on gc7000.

We have USB working here, e.g. https://developer.puri.sm/Librem5/Development_Environment/Boards/HowTo/Ethernet_over_USB.html and https://source.puri.sm/Librem5/linux-next/blob/imx8-linux-next-devkit/arch/arm64/boot/dts/freescale/imx8mq-librem5-devkit.dts

@agx it looks textured to me :) but chromium doesn’t work, for example... black window and GL out of memory errors

@mntmn but there's no texture descriptor support in mainline mesa yet for gc7000 (just checked again). Sure you're rendering via the render node?

@agx sorry, you are correct. i have some patches for this that i agreed not to disclose/share because they're not ready yet, but i assume they will be released very soon.

@mntmn ah...that makes sense. our gc7000 patches are public btw but they're not in a mainlineable form.

@agx thanks, but this is with fsl kernel i guess?

@mntmn nope, we're running mainline with a (compared to our 4.18 tree) rather small set of patches: https://source.puri.sm/Librem5/linux-next

@agx oh, ok, so USB _should_ work for me then. gotta dig deeper to find the cause
