The repository for linux-rt and linux-rt-lts has moved to a new location.

If you use the custom repository, please update your pacman.conf accordingly, as the other one is going away by the end of the month (January 2021)!

@dvzrv: Thanks for adding to the wiki! Very useful to know, especially as it is vital to the functioning of firmware updates. Just curious, though: is there a specific reason for disabling efivars in the rt-kernels? Does it impact performance in any way?

dvzrv commented on 2020-02-12 21:51

@kflak: It seems @Alvo alread provided the answer. Should've checked the mailing list earlier. These questions keep popping up from time to time :)

As a sidenote: I've added it to the wiki (for next time ;-) ).

@Alvo: efi=runtime kernel parameter seems to do the trick. Thanks a lot!

Alvo commented on 2020-02-12 14:35

@kflak Try adding efi=runtime to your kernel parameters.

@dvzrv: same story on linx-rt-lts. No efivars available there either.

kflak commented on 2020-02-12 10:54

@dvzrv: Thanks! I'll check the linux-rt-lts as well and see if this works.

dvzrv commented on 2020-02-12 10:49

@kflak: That's an odd one for sure. I'll try to reproduce this and get back to you!

@dvzrv: I marked it as solved because I accomplished my firmware upgrade objective by using the vanilla kernel. I'm using the prebuilt binary. Huge thanks for that, by the way! My glibc version is 2.31-1, linux-rt 5.4.17-rt9-2-rt

@kflak: Hm, I don't see why this wouldn't work. The config is the same as the config for the linux package in [core] in that regard (although there are other differences, which I'll look into in the coming weeks).

Did you rebuild this package for or did you install it from the unofficial repository in that version? If you're still on, but have glibc 2.31 there might be breakage and you should rebuild/upgrade.

Also, why do you mark the topic as [SOLVED], if it isn't solved?

linux-rt is not able to mount efivarfs on my system. With the vanilla kernel this works fine. Any pointers? For more details, check my post on the forum:
