14:42 <anthony25> I was using a patch from alexVinarskis[m] (iirc) for a while on the x1e, it works well

15:30 <steveej[m]> after a system and kernel update bluetooth is no longer working on my x13s. `bluetoothctl` can't find any controller. i checked that rfkill is unblocked. kernel seems to be happy with bluetooth. i see:... (full message at <https://matrix.org/oftc/media/v1/media/download/AboxE3o5StToc59Y-WJQsvakf19ozSFEDfSOFvr45ZSBPzAJ8vgSthqwRiv7rGX38R70EQR7GZ_3vJVTLQsUNPlCeZFVntWgAG1hdHJpeC5vcmcvem5JcENCWFRNYkJ0aW1xRWVZY2loeGFS>)

15:31 <travmurav[m]> missing mac address?

15:31 <travmurav[m]> if the previous kernel was quite old, at some point while ago the driver was changed to refuse to work with unset mac

15:32 <travmurav[m]> there was also a bug in the bt utility that didn't allow setting mac/etc, not sure if that was fixed

15:33 <steveej[m]> i have a systemd service for setting the mac. if i manually run the script it indeed doesn't work:

15:33 <steveej[m]> Unable to send Set Public Address cmd

15:33 <travmurav[m]> yeah probably the bug then

15:36 <travmurav[m]> https://github.com/bluez/bluez/issues/1394 it was fixed at some point I guess

15:37 <steveej[m]> just checked and that fix hasn't been released yet. i'm running the buggy bluez 5.83 on nixos unstable

15:38 <steveej[m]> thanks for pointing that out

18:32 <clover[m]> Spent a lot of time debugging grub-btrfs only to find it didn't like the initrd name lol

18:38 <JensGlathe[m]> I use btrfs, but boot from ext4

18:38 * clover[m] uploaded an image: (152KiB) < https://matrix.org/oftc/media/v1/media/download/Af9SMmSqt6rrkj4u7jExK-EvSoyfPJjR1iBwIdzAErwOquMWxcMi-nV2PXZkcr0Qby0FXTRjtRBoILnr5-EfldFCeZFgZHnwAGlyb25yb2Jpbi5uZXQvTHpGbW9HRFZlaE1kUkxXdUFUQmFUamVX >

18:39 <clover[m]> This was the fix basically. The probe needed something a little less customized

18:40 <tobhe[m]> yeah not sure if i'd trust grub filesystem drivers other than ext

18:43 <clover[m]> I dont want to look at another bash script for a while ugh

19:27 <JensGlathe[m]> as I recommended

19:33 <tobhe[m]> nothing wrong with btrfs imo but when you are using it for /boot you are using the grub implementation, not the Linux one for that

19:35 <tobhe[m]> afaict even fedora doesn't do that and probably for a reason

19:39 xeliteCJF has joined #aarch64-laptops

20:13 <robclark> yup, fedora has fat/esp partition so grub isn't involved w/ btrfs

21:34 <jdb[m]> Why is the patch series for the 4-lane support changing only the ThinkPad X13s devicetree? I guess other devices will have to get the same change upstream too?

22:33 <clover[m]> TIL about AES acceleration. It sped up my data migration a lot. protip if you are scp between arm servers and they have AES acceleration use Ciphers aes128-gcm@openssh.com

22:35 <clover[m]> default: ~76 MB/s.... (full message at <https://matrix.org/oftc/media/v1/media/download/AU1LcIUVtLQ8qLZuF64OfhrHv7HcBK49oOh7bXY0q85Y5NUvU1iO4SRoQmrwlOBIMZVHa2-Itwaw7vSwgBCE9IlCeZFt8YmQAG1hdHJpeC5vcmcvZVdlV2p1UXhMU1VHU0tHR2NxdVNoVUVE>)

22:39 <HdkR> Is this just AES instruction usage?

22:41 <clover[m]> yes

22:41 <HdkR> I'm surprised it's only 110MB/s

22:42 <clover[m]> it could be more, but i think thats about the cap for gigabit ethernet

22:42 <HdkR> ah I see, over the network

22:52 <Jasper[m]> There's a luks benchmark I think that does some transfer speed tests aswell iirc

22:52 <Jasper[m]> forgot what it's called

23:17 <clover[m]> migrated synapse and some other self hosted stuff from a rockpro64 to windows dev kit 2023. hopefully btrfs plays nice with me

23:30 <HdkR> I played a bit with btrfs directory compression a few days ago. It works surprisingly well.

23:31 <HdkR> As shame you can't set compression level per directory, only compression type, but still pretty cool.
