Has there been any progress with this? I know followmsi is done with LinageOS 17.1 for the Pixel C, I don't know if that means hes concentrating on 18. At the very least his appears to be done with this kernel development. I've seen in his change log and issue tracker that due to the pixel c's old nvidia codec, video in the browser doesnt work in all cases. I dont know if this kernel development will have any impact on the revocation of the L1 widevine support, but any information is appreciated. Thanks for all the hard work you all put into keeping these old devices working as well as they are, that is truly appreciated.I can see that Aaron is busy with Lineage 18 trees for Nvidia devices. Not particular just for ours but all of them so I think that work on the kernel side of the pixel C is not yet continued. You can follow his work here:
I will check if we could do a kernel build for lOS 17 in it's current state for people to try.
