So I don't know where to look. The code that fails is here https://github.com/freebsd/drm-kmod/blob/5.10-lts/drivers/gpu/drm/drm_mm.c#L167 and https://github.com/freebsd/drm-kmod/blob/5.10-lts/drivers/gpu/drm/drm_mm.c#L531 > Doug > > On 12/18/22 10:09, Emmanuel Vadot wrote: > > On Sun, 18 Dec 2022 19:34:19 -0500 > > Adam McDougall <mcdouga9@egr.msu.edu> wrote: > > > >> Hello, > >> > >> I have a Dell R6525 which I use to make new FreeBSD builds from -stable > >> and distribute them to other systems as upgrades.

As part of my testing yesterday (and what I described) was that I pulled down latest stable/13 and latest ports. Cleanly recompiled world, kernel, and drm-510-kmod but the system freezes when loading the amdgpu module. From my understanding drm-kmod is just meta port which will bring in drm-510-kmod so recompiling drm-kmod itself won't make s difference if I already recompiled drm-510-kmod. > >>>> > >>>> Jonathan Vasquez > >>>> PGP: 34DA 858C 1447 509E C77A D49F FB85 90B7 C4CA 5279 > >>>> Sent with ProtonMail Secure Email > >>>> > >>>> Sent from Proton Mail mobile > >>>> > >>>> -------- Original Message -------- > >>>> On Dec 17, 2022, 03:51, Emmanuel Vadot < manu@bidouilliste.com> wrote: > >>>> > >>>>> Hello Jonathan, On Sat, 17 Dec 2022 02:42:42 +0000 Jonathan Vasquez wrote: > Oh, I think I understand a bit better what you meant. Yup, after I found which stable/13 commit was problematic, I compiled HEAD~1 which still works, then I recompiled drm-510-kmod and it's working now. But I still wanted to report it since I'm guessing there will need to be some tweaks made to drm-510-kmod so that it works again with the latest stable/13. There is no tweaks to be done for drm-kmod. In fact in the last two days to commits who broke KBI between 13.1 and stable/13 were taken care of (one I've reverted and the other one being the one Doug fixed). Yes it's a bit unfortunate for stable/13 users that we broke KBI a few times and that you needed to recompile drm-kmod for it to work but what I want is when 13.2 is released users don't have to recompile the ports and can safely upgrade their machines (as the drm-510-kmod port will be compiled on 13.1 for 3 months).
