in the case of image processing it was "we paid a lot of money for it so you cant have it without drm"

>The GPU contains a very sophisticated ISP - the pipeline of image processing to get some raw camera data to pretty JPG's. This pipeline also needs to be 'tuned' to the particular camera and this can take some times (months for a specialised team to do a really good job) >All the work above needs to be done for each new camera module - and will be done for any camera sold for the Raspi.

Raspi cameras ship with drm https://gist.github.com/marcan/6dde73a9a0c917cd4fc9784a0a73e...

libcamera also supports the rpi and moves all of that control loop stuff into linux userland, so you would think there are no secrets left

but the actual register writes to drive the ISP are still in the blob, and libcamera is just telling the blob how to tweak every knob in the hardware

it makes no sense why they have opened it up so much, yet still insist on keeping that last bit a secret
