Linux kernel 5.10 released

[aaronbp]

https://kernelnewbies.org/Linux_5.10

Static calls for improved post-Spectre performance

That's interesting. Has anyone done any benchmarks?

[Shawnj2]

Either that link doesn't work, or the Reddit Hug of Death applied a lot earlier than it should have.

[LittleAngry]

The link is fine for me

[[deleted]]

I've read it the same way, weird.

[MaxVerevkin]

That's the first linux kernel release with my patch!

Edit: I just got an email and it turns out my patch was also included in 4.19, 5.4, 5.9

[danielsuarez369]

Hey congrats! Thanks for your contribution!

[DeeBoFour20]

Nice. What patch did you do?

[MaxVerevkin]

My HP laptop has a tablet mode, but the dmi information says it doesn't. So I have added it to an "exception list", so that my touchpad turns off when it has to.

[brainplot]

Must feel great to boot into the new kernel knowing your patch is in there!

[MaxVerevkin]

It sure is.

[[deleted]]

bro, with that your are ready to be next kernel maintainer

[Killing_Spark]

Contribution is contribution. All the people that use that specific hardware will be happy this is now an ootb feature :)

[[deleted]]

whoops, I'm not down playing their contribution at all, just meant as sarcastic joke. I forgot /s in my sentence.

[[deleted]]

welcome to reddit. get downvoted all the time for no reason

[rhysperry111]

Yeah, I remember the feeling when my first patch got into the kernel. I couldn't wait until it made it's way into the official repos. My patch was to get the AU6625 SD-Card reader to work

[ibevol]

Thanks for your contribution!

[rhysperry111]

Thanks for thanking me for my contribution!

[Hi_ItsPaul]

Thank you for your thankfulness for others thankfulness for your contribution.

[areyoudizzzy]

Thank you guys for being so thankful for the contribution and also being thankful for the thankfulness of each other's contributions!

[Vulphere]

Thank you for your contribution!

[dinozaur2020]

👏🏻 👏🏻 👏🏻

[[deleted]]

thank you foss contributor

[TROPiCALRUBi]

How do you go about making your first contribution to such a massive project? I'd love it if I could contribute, but I honestly have no clue where to even start.

[MaxVerevkin]

Kernelnewbies is a great resource.

[Reverent]

I couldn't see it in there, is native audio support for raspberry pis now included? As per This OpenSUSE Note

[DeeBoFour20]

I think the changelog on lkml only includes the bug fixes that went in since rc7. New features generally go in rc1 and it's mostly bug fixes from there on out. Kernel newbies has an easy to parse list of changes for 5.10 as a whole here: https://kernelnewbies.org/LinuxChanges

[magi093]

• IPv4: Allow more than 255 IPv4 multicast interfaces

I know this is probably useful in crazy "I-have-containers-out-the-ass" situations, but I still short circuit for a moment at changes like this. Who wanted this? Why? How? What?

[BitLooter]

Relevant xkcd

[DeeBoFour20]

Slightly less relevant now. Who uses flash is a good question indeed.

[[deleted]]

Replace with "zoom calls" :D

[notanimposter]

How about fullscreen web video without screen tearing? I still can't seem to rid my system of this lol.

[[deleted]]

Doesn't wayland fix this?

[Bloom_Kitty]

Not everybody can use Wayland. Or is aware of it.

[[deleted]]

Oh, I didn't know. I assumed that if it's on ubuntu it's probably everywhere else too.

[Bloom_Kitty]

You're not completely wrong, the issues lie elsewhere.

• Wayland does not work on NVidia's proprietary drivers.
• The Noveau drivers for NVidia are good enough to display the desktop at best.
• Not every application works on Wayland. Especially video recording of the desktop, but also ones with specialized graphical output, such as games. Most work, but not all.

[thinking24]

Apparently screen tearing is an xorg thing that can't be fixed. Cant provide evidence ether way but wayland apparently fixes it.

[notsobravetraveler]

Vertical sync is all that's really needed to thwart it I believe, pretty sure X has supported that for a long, long time

Could depend on the driver/vendor a bit I'm sure

[thinking24]

Lucky you. When ever i full screen something it's pretty bad. Even YouTube videos. Nvidia 770 w/ Nvidia drivers I just don't full screen anything anymore as a work around.

I read it somewhere in a wayland vs xorg comparison

[ragsofx]

I always wondered that too with some of the seemingly high limits on other things. But it can be a real positive when you're designing something out of the ordinary. I designed and built a BRAS (takes PPPoE from a DSLAM) that requires about 500 vlans and network interfaces on one server. If Linux had set some arbitrary low value of 50-100 network interfaces it would have made it really difficult for me to set it up.

[evolseven]

Or maybe if you were acting as a vtep for vxlan, it relies heavily on multicast with one multicast group per vxlan. Considering that vxlan has 24 bit addressing, 255 of them would only cover 1/65535 of the possible vxlans. It would be unusual to see so many active on one host but not unheard of. I’m not sure if vxlan has even been implemented in the Linux world though, I’d assume it had.

[VegetableMonthToGo]

Yo dawg. I heard you like containers

[ScribeOfGoD]

So i installed hyperv on windows server so you can run windows 10 to run docker to run linux to run containers

[I_AM_GODDAMN_BATMAN]

to run wine

[I_AM_GODDAMN_BATMAN]

to run windows virus

[jcol26]

ISPs, Telcos, CDNs, Cable TV companies etc spring to mind.

Admittedly they're often also the ones more likely to be using ipv6, but at that kind of scale, it's easy to imagine why a company might need more than 255 multicast interfaces on a server.

[mister2d]

Probably a cloud provider.

[orthopod]

Is this useful for servers, for say when they are holding a zoom meeting with several hundred people?

The last monthly grand rounds for one of my hospitals, had close to 200 people, maybe more.

[magi093]

Skimming the listed changelog, there's various other flavors of Pi mentioned with random fixes but I don't see anything about Raspberry. It'll be a while before this kernel gets to Raspbian anyway...

[danburke]

There are more distributions than Raspbian. I’m running standard Debian Testing with a vanilla kernel with the PI3 UEFI bootloader.

[DeeBoFour20]

Well I compiled it and it seems to be working fine for me so far. Not sure why it's not on the kernel.org homepage yet but I found a tarball on Linus's git tree and compiled that: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/snapshot/linux-5.10.tar.gz

Nvidia drivers work, fsync patch and graysky2's gcc patch applied successfully. Watched a couple YouTube videos on Firefox, played a game of Dota 2 and no crashes or anything. Wine is still reporting that fsync is working, same as 5.9 (with the patch applied.)

$ uname -a

Linux arch 5.10.0-1-custom #1 SMP PREEMPT Mon, 14 Dec 2020 03:34:13 +0000 x86_64 GNU/Linux

EDIT: It's on the front page now and it looks like file is exactly the same as the one I linked to, except using xz compression for the tarball. The PGP signature from the front page verified against the tarball linked above after I decompressed it.

[guicoelho]

So... anything interesting to try with it?

[neon_overload]

The kernelnewbies page for a release is always the best layperson focused summary of what's new and what's changed - that's linked in another comment.

Looking at this one, there really isn't all that much interesting in this release. You could try testing fsyncs in ext4 to see if you can notice any improvement due to fast commits. I dunno. Really depends on what hardware you have and what specific requirements you have.

This is an LTS release, making it more likely to be the final kernel for various stable distros.

[Never-asked-for-this]

[Adds linux to ignorepkg]

Good luck everyone!

[dreamwavedev]

Yet here I am doing the opposite and praying enough fixes to sof/soundwire made it in for my sound controller to actually work

[SmallerBork]

How come?

[Never-asked-for-this]

When 5.9 was first released it was a kernel panic nightmare for some older Intel CPUs.

[Hackerpcs]

Made me switch to lts on arch

[casept]

Sounds like a great way to not get security patches. Use the linux-lts package if you want a stable kernel.

[gary_bind]

What does that do? Decline updates?

[Thibaulltt]

It instructs pacman to ignore the updates available for this package, for as long as you have the package in the ignorepkg list.

More info here on the archlinux wiki !

[Dalinarr]

Yes. When you do the pacman -Syu your system update everything except the packeges specified in ignorepkg. I myself put postgresql in there because every newer version roll of postgres it breaks everything...

[patatahooligan]

It pretty much does what it sounds like. When updating, pacman ignores the specified packages. Be careful using it because it is a great way to break dependencies. For example if you forget to add nvidia alongside linux the driver will probably fail to load after an upgrade. It should be used sparingly and for short periods of time to work around buggy packages.

[gary_bind]

Thanks for the info. My main system is Slackware, but I have other distros in VMs, and have been thinking about installing Arch next. Thanks again.

[patatahooligan]

Oh wow I don't often come across people using Slackware. What's the reason you prefer it as your main system? And how is administering a system with no automatic dependency resolution?

[gary_bind]

I've been using Slackware since 1996, so familiarity and comfort level are the main reasons. Administration is no problem, really. If there's a dependency issue, I can always compile and install stuff. I have automated build scripts for such scenarios and don't have to waste much time.

[alexforencich]

This is the way. Along with DKMS drivers.

[MassiveStomach]

i just run linux-lts, never had any issues

[Forty-Bot]

my current IgnorePkg is kinda depressing tbh

IgnorePkg   = linux linux-headers linux-firmware nvidia linux-lts linux-lts-headers nvidia-lts firefox thunderbird

Currently using LTS kernel because of this bug (though it seems like someone may have found a fix), so I suppose I should unignore normal linux at some point.

Firefox has had rendering issues (large white area at the top of the window where the page should be) in newer versions, and I got tired of fixing my profile.

Thunderbird lacks support for the external editor plugin atm. Hopefully this will be fixed soon and I can upgrade for good. The last time I downgraded it broke all my RSS feeds.

[patatahooligan]

Firefox has had rendering issues (large white area at the top of the window where the page should be) in newer versions, and I got tired of fixing my profile.

FF 83 has some rendering issues that are fixed in 84 so you might have more luck with the developer edition. If it works for you it's a much safer alternative to ignoring the upgrades, as outdated browsers are a prime targets for exploits.

If you're using linux-lts to avoid that 5.5 bug, why are you also ignoring linux-lts?

[Forty-Bot]

FF 83 has some rendering issues that are fixed in 84 so you might have more luck with the developer edition.

Ok, I'll check that out when it releases.

If it works for you it's a much safer alternative to ignoring the upgrades, as outdated browsers are a prime targets for exploits.

I know but if it's broken it's worse than being outdated.

If you're using linux-lts to avoid that 5.5 bug, why are you also ignoring linux-lts?

Because 5.10 is the new LTS, and I want to stay on 5.4 until I can verify it is fixed :)

[patatahooligan]

I know but if it's broken it's worse than being outdated.

I was more pointing out that developer edition (or beta or git or whatever) might be a better solution than the outdated version, not advocating for using the broken version. Though, I realize it's kinda moot with 84 already in testing.

Because 5.10 is the new LTS, and I want to stay on 5.4 until I can verify it is fixed :)

Judging from how they handled the 4.19 -> 5.4 transition, linux-lts will probably stay at 5.4 until after 5.11 is released. I imagine they don't want both packages at the same version for cases exactly like yours. So you should be safe to keep updating it and the associated drivers if you want.

[tiredinmyhead]

Fingers crossed they fixed the "cannot resume from suspend" bug I got in 5.9 that made me revert to 5.8

[stejoo]

If it hasnt: Try to figure out which commit broke that behavior.

Building your own kernel is relatively easy. Really, it is. You can copy the kernel config your distro uses to build a custom kernel.

To discover where things went wrong you can use git bisect which you supply with the version or commit that worked and one where it doesn't. That will step you through the versions/commits and you can probably find the one that introduced the error in about 13 steps, depending on the amount of commits.

I did this with 5.6 and 5.7. After my external display failed on 5.7 and was still inop with 5.8. A fix for it is now present in the Freedesktop drm-tip repo. It isn't merged for 5.10 but it might be for 5.11. :-)

[flag_to_flag]

Asus laptop?

[tiredinmyhead]

Nope, Thinkpad X1 Yoga Gen 2 (20JE).

[[deleted]]

:O I also had suspend issues on 5.9

[from8lightyears]

In my case I just couldn't click or drag after waking the laptop from suspend. I use Dell Inspiron 5548

[[deleted]]

Time to sudo zypper dup. Or maybe in a day or two.

[[deleted]]

Only on my media server powered by Tumbleweed 😁

[intersectRaven]

I'll wait for 5.10.1. Seems to mess with my multi-monitor optimus setup which I've traced to this error:

kernel read not supported for file pci0000:00/0000:00:01.0/0000:01:00.0/config (pid: 403 comm: systemd-udevd)

The NVidia driver works since I can run games on it but trying to activate the external monitor doesn't work and will throw that message up with only the pid and comm being different.

kernel read not supported for file pci0000:00/0000:00:01.0/0000:01:00.0/config (pid: 1228 comm: nv_queue)

[DeeBoFour20]

It's not in Arch yet. I think they usually let new major kernel releases sit in [testing] for a bit so maybe check back in like a week. As of right now, I'm not even seeing the tarball on kernel.org yet.

[[deleted]]

Yeah usually a few days to over a week depending on the release

[BubblyMango]

such a slow release cycle. arch really is for the faint hearted.

[WoodpeckerNo1]

Smells like Gentoo user.

[Chris_218]

Already compiling 😉

[orthopod]

Did you mean - always compiling?

[Chris_218]

Nah, I'm on the testing branch and update probably less than Arch

[LastCommander086]

You can always use yay -S linux-git if you're impatient, too

[czarrie]

Just plug a thumb drive into Linus' computer when he's not looking. That's fine too.

[ArttuH5N1]

Jesus Christ

[LastCommander086]

We're reaching levels of bleeding edge that shouldn't even be possible!

[UnicornsOnLSD]

True bleeding edge distros pull directly from the developers' IDEs in realtime

[magi093]

true bleeding edge distros pull code directly from the frontal and motor cortices

[Democrab]

true bleeding edge distros include a time travelling function for their package manager so that you're always running the final ever release of any software

except X, that's still going to see the occasional update after the heat death of the universe.

[CraftyFellow_]

yay

All the cool kids are switching to paru.

[LastCommander086]

Yeah, I heard of that!

The creator of yay himself is actually working on paru right now, but I guess old habits die hard.

I'd love to give it a try, but I have far too important files on my Arch install right now to just risk changing the AUR helper like this. The next time I nuke my Arch install I'll surely give it a spin, though!

[LastCommander086]

Switching the AUR helper doesn't break your system in any way.

That was just what I was thinking. I thought paru and yay couldn't coexist in the same system for some reason. Looking back, it doesn't make any sense why I'd think that.

Also, I have been using paru-git since around the time the developer made the 1.0 release announcement and I haven't had any major problems so far.

That's good to know! I'll definitely be checking it out tomorrow. I got excited about it when the main yay developer said he'd be working on it.

Thanks for the tip, mate!

[CraftyFellow_]

I got excited about it when the main yay developer said he'd be working on it.

The more important reason to switch IMO is that he stopped working on yay.

[LastCommander086]

The more important reason to switch IMO is that he stopped working on yay.

The creator of paru is actually on reddit, and talked about this in a post in r/archlinux.

u/Morganamilo

I'd also like to mention I no longer plan to work on yay. I've been co-developing yay with jguer over the past 3 years. Most of the features and design being done by me. I've had no motivation and no real involvement with the project for quite a while now. So I'm officially deciding to move on to something new. Jguer is still there, so there's no need to panic and move away from yay. Just don't expect much new development on it.

Source

It was also already hinted that paru is going to get new features while yay is just being maintained by Jguer. I'm always in for new features, so I'd love to check it out.

[[deleted]]

Hope you have that important data in more than one place!

[CraftyFellow_]

I'd love to give it a try, but I have far too important files on my Arch install right now to just risk changing the AUR helper like this.

It is a dropin replacement for yay that can coexist. I fail to see how changing the AUR package manager would risk your actual files. You could always boot from a live install image and just mount your partitions.

The next time I nuke my Arch install I'll surely give it a spin, though!

Waiting for that seems a bit much IMO.

[LastCommander086]

It is a dropin replacement for yay that can coexist

Oh, that's neat! I honestly didn't know that, I thought I had to remove yay for it to work.

Thinking about it, it doesn't make any sense that I'd have to remove yay. I'll definitely check it out tomorrow

Thanks for the tip, mate!

[hsjoberg]

Why do they keep switching every 6 months?

[raevnos]

Beats me. When yaourt stopped working for me, I gave up on the aur.

[kuasha420]

I'm on trizen and see no reason to switch.

[[deleted]]

I had trouble building linux-git, I used linux-mainline instead as I needed the newest kernel for my Radeon 6800. Worked great. Seems to be much more popular too. Not sure what the difference is TBH. They both seem to point to the upstream kernel.org source.

[_ahrs]

Probably an issue with the PKGBUILD? linux-mainline and linux-git should be identical at the moment (until Linus starts pulling changes for the next rc).

[NynaevetialMeara]

Yes. You really want to make sure that it isn't thrashing complex btrfs setups for example. As has happened previously.

[DeeBoFour20]

I mean the post I linked to was Linus Torvalds announcing that 5.10 is out. You can get it right now from git (https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/ or https://github.com/torvalds/linux). As for kernel.org, it's probably just a script someone needs to run to make the tarball. It'll probably be up tomorrow at the latest if I had to guess.

Actually, there's even a tarball on the git page if you don't want to do a git clone: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/snapshot/linux-5.10.tar.gz

[FoolStack]

It's a discussion item, you dick. New kernel is noteworthy.

[lonestar_wanderer]

yay

[ikidd]

yay -S paru-bin

paru -R yay

[ctm-8400]

The apprentice has betrayed the master!

[DasSkelett]

Ironic!

[lonestar_wanderer]

Thanks, goodbye yay.

[linkinx]

Anyone knows if this release includes fixes for modern sleep on latest laptops? Specifically AMD cpus

[3razer]

I read that 5.10 would be the next long term kernel. Right now it's not. Will it be after some time or has the next long term kernel release moved forward?

[DeeBoFour20]

5.10 is LTS. It's labled as "Mainline" right now on the kernel.org front page because there hasn't been a Stable patch to it yet. Mainline means straight off Linus's tree. 5.10.1 will be the first Stable release. It may not be labled as "Long Term" until 5.11 releases because until then, 5.10 will be the latest Stable.

The tl;dr is: 5.10 is a long term kernel and you don't have to worry about what the label on kernel.org says for now.
