> that would be fine if you could load fkms on demand. I'm guessing that's not an option though? No

What OS are you running? Not having raspinfo/vcgencmd and the old date in "Raspberry Pi reference 2019-07-10" suggests it's not a recent RPiOS image.

This isn't an issue I've seen reported elsewhere. "Oops - undefined instruction" suggests memory corruption of the kernel code. That can be caused by overclock or power supply issues. Can...

Are both planes 32-bit RGBA? Are either planes resized (which is a more expensive operation)? one 1920x1080 32-bit RGBA plus one 1920x1080 YUV plane does work on a Pi3 with...

If you don't use the primary plane yourself, it will still be present (as an obscured framebuffer console) and will still be using HVS cycles and sdram bandwidth. RGBA32 1920x1080@60...

There is only one primary plane. The console will only ever have been using the primary plane. If you make sure you always use the primary plane then the console...

The latest rpi-update firmware contains a potential fix for this issue.

This does change the script from being for cross-compiling (i.e. building on a linux pc) to a native compile (on pi).

The SPI clock is a divided down version of the core clock. The core clock reduces when arm is not busy. If you want to force the full speed of...

The core clock changes outside of the spi driver's knowledge. Therefore it assumes the highest frequency and will run slower when the core runs slower. Typically core_freq=500 core_freq_min=200. So when...
