Busy on other stuff at the moment. I'll have a quick look when I get a chance.

Yes, I work at Raspberry Pi. Docs for V4L2 I had already linked to - https://linuxtv.org/downloads/v4l-dvb-apis-new/uapi/v4l/pixfmt-srggb10p.html It's part of the CSI2 spec (I would link to it, but it's closed...

I'd somehow totally missed this one, but it's been brought up through #6242. If I'm reading it correctly, you're effectively trying to hack the DRM mode around to influence the...

Yes it creates source changed events should the resolution on the CAPTURE queue change. If you program the CAPTURE queue in accordance with the stream, then there is no change,...

The Pi has a bitstream parsing FIFO which IIRC is 2MB in size. It'll swallow OUTPUT buffers until that FIFO is full. V4L2 mandates that there is one NAL per...

> A stateful decoder should be able to generate that event per the specification: https://www.kernel.org/doc/html/latest/userspace-api/media/v4l/dev-decoder.html#initialization > > Setting up the CAPTURE queue prior to start sending the stream is kind...

Kernel module bcm2835-codec has a module parameter "debug". Increase that to 5 to get all the logging out of the module. You should get any format changed callbacks logged via...

I'll dig out my patches again. Is there a quick and easy test (for someone who has never used rust at all) that I can run?

If you're after an open source driver for these panels, could you try https://github.com/raspberrypi/linux/pull/5433 ? It's been verified on the 2.8", 7", 7.9", 8.0" and 10.1" panels.

If you are running 6.1.54 built from the https://github.com/raspberrypi/linux repo, then adding `dtoverlay=vc4-kms-dsi-waveshare-panel,` to config.txt should configure your system to look for the appropriate Waveshare panel. See the Waveshare wiki...
