13:43 <jannh> is there a guide somewhere on how to run a mainline kernel you've built yourself on the rock 5b? (or is that a bad idea and I should be using another tree?)

13:47 <jannh> should I be using https://gitlab.collabora.com/hardware-enablement/rockchip-3588/debian-image-recipes ?

13:57 <CounterPillow> Most stuff should be in 6.11, so just building the mainline kernel from kernel.org will work if you have all the right drivers enabled. But the debian images from collabora are definitely an easy way to run something close to mainline

19:14 <jannh> wow, that was easy, I just built an upstream kernel, installed it as normal, rebooted it, and the machine comes up. I did not realize running a custom kernel on an arm64 system could be this easy

19:15 <jannh> magical

19:15 <jannh> well, not entirely magical, my display doesn't show anything, but that's fine, I really only need my ssh shell ^^

19:20 <jannh> (and the kernel is complaining that the collabora debian image doesn't have the firmware-realtek package from non-free-firmware)

19:28 <bluetail> CounterPillow jannh from 6.10 to 6.11 there are a couple regressions. I just faced https://forums.gentoo.org/viewtopic-p-8845746.html today. So now my server is on LTS.

19:32 <CounterPillow> why would that be relevant to rk3588

19:34 <bluetail> I tried to say, please start testing from the earliest supported kernel, then work your way up, recent kernels have regressions.

20:03 <CounterPillow> every kernel has regressions

20:06 <bluetail> Even the first kernel ever made? Sorry. This is too much what about for me :D

20:31 <linkmauve> bluetail, the point is, instead of staying on LTS forever, it’s much more helpful to run mainline and to report the regressions you find on the way.

20:32 <bluetail> Thanks for the clarification. Appreciate it.

20:32 <linkmauve> Although last time I did find a regression, it had already been fixed a few days before but not yet in mainline, only in drm-next or something.

20:38 <CounterPillow> bluetail: you won't get any less bugs running older kernels. Even LTS branches that just get fixes backported introduce new regressions (see, recent ext4 corruption bug). "But new kernel has some unrelated bugs to the platform at hand" is not useful information.

20:40 <bluetail> but when I used most recent one, my disk went into read-only state despite nothing wrong, I guess using the old kernel is better for me at the moment... I need to use the machine, maybe I should just upgrade very rarely on my server

20:57 <jannh> ah, my usecase is different, I just want to tinker with the newest panthor driver
