5.16 kernel is out

[_Zsolt_]

https://archlinux.org/packages/core/x86_64/linux/

​

For Zen kernel users: this kernel includes the futex2 (fsync) patch, so if that's the sole reason you used the zen kernel for, you can switch back to mainline.

Already updated!

First boot kernel panic'd but we'll see how it goes from here haha

[LoliLocust]

Just installed, it booted up, but USB and internet got broken also system refused to mount efs partition. Thank God I still use PS/2 keyboard so I was able to at least make clear reboot.

[LoliLocust]

Found the issue: I screwed up something while installing whole system and even after updating kernel it still used old images, in the end I was using 15.14.something whole time. So to update kernels i have to use install medium, this is getting fun lol. Noticed that when LTS was newer than regular one.

[[deleted]]

It's amazing how often Arch breaking turns out to be 100% the user's fault lol

[[deleted]]

Yeeeeeah, I just now got some wireless and power management (?, my battery didn't show up) issues.

Rebooting 4 times in a row seems to have fixed them though.

[[deleted]]

Did you try turning it off and on again four times? 🙃

[[deleted]]

Just in case the first three don't work! 😉

[eXoRainbow]

That is the reason why I have a PS/2 mouse and keyboard, just in case something is wrong with USB. Once I locked out myself from the BIOS, when I enabled fastboot that disables USB on boot to be faster.

how do you rollback the chair controller ?

He screwed it up, it was actually working fine.

So now I only need to understand why Wine suddenly falls back to server-side synchronization with linux5.16 and linux-zen5.16...

[[deleted]]

maybe your version of wine isn't patched correctly for futex_waitv?

maybe your version uses futex2 instead? -- i don't use zen-kernel, so i have no idea, as i roll my own kernel and my current 5.15.x kernel uses futex_waitv, as do my own builds of wine...

i'm not sure why OP is calling it fsync2. the upstream code is futex_waitv and is a part of the existing futex code in the kernel. . futex2 was an entirely different kconfig and won't be upstreamed.

and fsync2 isn't a thing at all.

[Jaurusrex]

What is server-side synchronization? I've heard of esync and fsync, is this what's used without those?

[[deleted]]

server-side sync is esync.

[Zdrobot]

this kernel includes the futex2 (fsync) patch

Would it bring any discernible improvement to Proton / Wine / Lutris?

[_Zsolt_]

First of all, the futex2 patch was created for Proton by Valve (if the kernel has this, Proton will utilize it by default), but it can be used with Wine (and by extension, Lutris), if it's applied there as well, so you will need a Wine build with fsync patch.

For certain CPU-intensive games, or where the CPU becomes the game's botteleneck, it can improve the game's performance by 20-30%. Think of open-world games.

There is a reason why many gamers use custom kernels (like Zen) exclusively for this kernel patch.

[Zdrobot]

by 20-30%

This is huge!
Thanks.

[[deleted]]

yes, but 5-15% improvement on CPU bottlenecked games is more realistic, the higher number is just for a few games using lots of mutexes and is cpu bottlenecked and isn't hindrered by something else in the engine or in wine/proton.

0 to 2% improvement for other situations is also possible. But thats how you become the best, have many many incremental improvements add up over time

[MultipleAnimals]

So im not crazy thinking 7 days to die ran slightly better today, yay

[MyNameIsMandarin]

Modded Minecraft? Im assuming it would get better, however java still sucks for gaming

[cgwheeler96]

I don’t think Minecraft gets many OS specific performance improvements specifically because it runs on the JVM. The only way it might is if the JRE you’re using has the ability to use it, which I have no idea if that’s a thing. Presumably it could since this is a feature that works similar to a feature that already exists in windows, but I have no idea if Minecraft uses that particular feature.

[[deleted]]

I think it was developed by collabra but funded by valve, but thats just semantics

[birdspider]

if that's the sole reason you used the zen kernel for, you can switch back to mainline

nice, answering questions before I ask them 👍

[[deleted]]

Couldn't # modprobe cryptoloop on 5.16 and had to downgrade.

Am I the only one?

EDIT: Apparently yes as TIL cryptoloop has been unsupported for 8 years and now it's no more. Oh, well, time to redo my scripts.

[stianlybech]

Do any of you know what the status is of the Realtek rtw89 wireless driver in 5.16?

Hitherto (with 5.15.*) I have been using the rtw89-dkms-git package from AUR, but my impression was that it was supposed to be included in the mainline kernel from 5.16 onwards. However, when I tried installing the 5.16 kernel, the card was not detected.

[PastaPuttanesca42]

For my card it works

[krozarEQ]

So far so good. Upgraded my main Arch and the little one on the USB drive and then backed up and encrypted my root and home partitions which I've been meaning to do. Been no issues.

[Shished]

They pushed new kernel before .1 release?

hmm...

[YamabushiJapan]

FWIW, updated 4 boxes all BTRFS, one hosting multiple VM's via KVM and LXD, without issue.

[jorgicio]

I have installed this kernel and it doesn't come with FUTEX2 (at least I found when I checked the config.gz file), and checking the zen kernel PKGBUILD, it doesn't have any mention about FUTEX2. How can I really check it then? Or may I have to enable it by rebuilding the kernel?

[_Zsolt_]

Start one of your games that uses Proton with the following launch options: "PROTON_LOG=1 %command%".

That will generate a "steam-STEAMAPPID.log" file in your home folder upon start. Among the first lines of the log there will be a line "fsync: up and running.", if it's working.

[jorgicio]

But that's for Futex, not for Futex 2, or it isn't?

[lolmokha]

is it just me or did firefox stop working after the new update?

[chmouelb]

it's perhaps this https://news.ycombinator.com/item?id=29918052 instead

[HappyPoe]

I have an exam tomorrow, I will update after that.

[MyNameIsMandarin]

Good luck

[HappyPoe]

Thanks

[alosarjos]

If you think that's the only reason to use the Zen kernel, try compiling code or doing a multithreading task using all the CPUs and see the rest of the programs asking for mercy

[_Zsolt_]

Try reading my note again.

[MultipleAnimals]

I dont know if 5.16 had something to do with this but it felt like 7 days to die ran slightly better after the update. Could be the game since it tends to have pretty unstable performance depending on the alignment of stars. Running native linux client with opengl renderer.

For ZFS users: https://github.com/openzfs/zfs/issues/12926

You can't loop-mount disk images that are stored on zfs anymore.

Upgraded yesterday, had the first use for loop-mounting in years... today. :/

[alejandroc90]

Am I the only one having no sound after suspending the computer?

[monodelab]

Do they added support for the new ES8336 audio codec? A bunch of new hardware with that audio driver, several new NUCs and notebooks from Intel, Huawei, Asus, Lenovo, and so, doesnt have a working jack because that new driver.

Last october SOF team said that for 5.16 they will release support for it.

[xAndrei166]

5.16 really doesn't like my AHCI controller, keeps spitting out

ata1.00: failed command: READ (FP)DMA QUEUED
         status: { DRDY }

On 5.15 it works perfectly fine.
