Just published a blog post talking about some iOS kernel framebuffer research I’ve been looking at over the last couple weeks. Have a read if you’re interested :)https://link.medium.com/3155zMpgm3

Really looking forward to when this is updated with support for more devices, though you said we could manually add in more devices... could you be a bit more specific on how we go about doing this? Also, what does this support? I'm assuming any device with tfp0?

To add support for another device you can follow the same process I outline in the post to find the address of the framebuffer. Then just use that address in the code instead of the one I have there by default :) yea should work on any tfp0 enabled device

you can also get an IOSurface from IOMobileFramebuffer and map that in userspace without tfp0 (it's gated by an entitlement, however)
