Bounty for SDM845 camera support (gitlab.com)

I would like to incentivize timely (1-2 months max.) implementation of pmOS camera-support for SDM845 devices by offering a bounty of 6 XMR (Monero, the digital cash). The intent to win the bounty has to be discussed here beforehand.

If supporting the entire list of devices implies significantly more effort than a subset, the minimum should be OnePlus and Shift. Details from comment:

When one opens a camera application (like millipixels), the screen should show what the camera points at and capturing color photo and video of that content should be possible. It should run in a stable manner (meaning no anticipated crashes) and the required changes should be accepted into the postmarketOS edge branch.

If bounties happen to be against the ethos of the project, let me know.

On the contrary, I hereby invite others to chip in.

Comment if interested.

Interestingly, I'm already planning to meet with one of the PmOS developers this weekend at FOSDEM to work on this. But I would probably say I'd recommend this bounty goes to either the PMOS or libcamera projects rather than myself if/when we get this completed.

Great. Maybe you can give a little heads-up after the weekend.

Quick updates here.

We managed to get the IMX519 driver probing successfully with the CCS driver (an alternative driver that should be able to run this module), but discovered that the camera is connected over C-PHY instead of D-PHY, which explains our earlier difficulties and inability to capture so far.

The good news is that, knowing that helps a long way to the next steps. The bad news is that as I understand it, C-PHY is not yet supported in the camss driver. So the next development steps are to first determine getting C-PHY support added, and then we can come back to testing and validating the IMX519. With a blocker on the C-PHY, for now I wouldn't expect this to be achievable in the next two months.

Thank you - are you looking at adding that support to camss yourself?

Kudos on the progress!
