Linux Kernel 2.6.21 Released

diegocgteleline.es writes "Linus Torvalds has released Linux 2.6.21 after months of development. This release improves the virtualization with VMI, a paravirtualization interface that will be used by Vmware. KVM does get initial paravirtualization support along with live migration and host suspend/resume support. 2.6.21 also gets a tickless idle loop mechanism called 'Dynticks', built in top of 'clockevents', another feature that unifies the timer handling and brings true high-resolution timers. Other features are: bigger kernel parameter-line, support for the PA SEMI PWRficient CPU and for the Cell-based 'celleb' Toshiba architecture, NFS IPv6 support, IPv4 IPv6 IPSEC tunneling, UFS2 write, kprobes for PPC32, kexec and oprofile for ARM, public key encryption for ecryptfs, Fcrypt and Camilla cipher algorithms, NAT port randomization, audit lockdown mode, some new drivers and many other small improvements."

Immediately modded down, and not even first.

Can you say pwnd?

Damnit!

[FunWithKnives]

And I just upgraded to 2.6.20-15! (Kubuntu Feisty Fawn)

please help...

[fattmatt]

I'm still running 1.0 Patch 9 ... should I upgrade?

That's nice and all...

[rob1980]

... but does it run Linux?

Another solution to a timeless problem!

[iamacat]

Once again, it took many months of work to optimize an idle loop.

who the h3!! marked that flamebait?

[1800maxim]

Must be Linus!

paravirtualization? Dynticks? new drivers?

[Anonymous Coward]

This seems like pretty good evidence that Linux is a kernel.

At last!

[Dr. Stavros]

Glad to hear that it's been published. Where can I download the PDF? I heard that Darl dies near the end, but I want to read it for myself.

Sooner or later...

[heretic108]

Sooner or later, my /boot/grub/menu.lst will look like:

...
title Ubuntu, kernel 2.6.29-5-generic
root (hd0,0)
kernel /boot/vmlinuz-2.6.29-5-generic root=/dev/hda1 ro \
  coffee=cappucino,sugar=0,hourly \
  massageareas=head,neck,shoulders \
  catfeedingtimes=4_hours,15_grams
initrd /boot/initrd.img-2.6.29-5-generic
quiet
savedef ault
boot
...

Re:That's nice and all...

[diegocgteleline.es]

Since it supports para/virtualization yes, of course, it runs linux!

(Damn, finally there's an answer for this!)

Re:You joke,

[Anonymous Coward]

I wonder if we're ever going to see 2.8 at this rate

Linux 2.8 will compete with SunOS 6.0 as the best platform for running Duke Nukem Forever.

Re:Hotplug CPU support!

[harrkev]

Hotplug CPU support? That must burn

Nope. Works great. Let me demonstrate...fsdjlksd+++

Re:You joke,

[Vulva R. Thompson, P]

Well, the upcoming sister-raping feature could qualify as "major".

Details: [kernelnewbies.org]
"The features are tested in the -mm tree, but be warned, it can crash your machine, eat your data (unlikely but not impossible) or rape your sister (just because it has never happened it doesn't means you're safe):"

Re:Does it still crash after 49.7 days??

[Cro Magnon]

497 day wrap around? You should switch to Windows. I'm sure no such problem has ever been reported on that OS.

Re:Sooner or later...

[ady1]

massageareas=head,neck,shoulders

In this revision, they've changed added a additional feature. Now the line is like:

massageareas=head[0],neck[0],shoulder[0-1]

Massage the wrong array member and the kernel will panic.

Re:Bloat?

[ehrichweiss]

Are you referring to the 2.4 days as actual compile time or time it took you to work out what to include in the kernel config? I don't think it ever took more than 8 hours to configure and compile a new kernel on my end even if the machine doing the compiling was 1/10th the speed of, then, current computers.

Plus, I don't find it THAT hard to configure the new kernels but I take my distro's config file and remove anything I know I don't need rather than starting with a blank-slate config and THEN trying to figure out what to include/remove.

catfeedingtimes=4_hours,15_grams

you forgot the

Right, brothers...

[Slashcrap]

But apart from virtualization with VMI, paravirtualization, live migration and host suspend/resume supportsupport for kvm, a tickless idle loop mechanism with unified high resolution timer handling, bigger kernel parameter-lines, support for the PA SEMI PWRficient CPU and for the Cell-based 'celleb' Toshiba architecture, NFS IPv6 support, IPv4 IPv6 IPSEC tunneling, UFS2 write, kprobes for PPC32, kexec and oprofile for ARM, public key encryption for ecryptfs, Fcrypt and Camilla cipher algorithms, NAT port randomization, audit lockdown mode, some new drivers and many other small improvements, what has Linus ever done for us?

Re:Published?

[Anonymous Coward]

At least they didn't publish it to Google, or it would be gone.

Re:You joke,

[einhverfr]

Linux 2.8 will compete with SunOS 6.0 as the best platform for running Duke Nukem Forever.

I dunno. Hurd will probably give them both a run for their money.

Anyway, isn't Duke Nukem Forever written in Perl 6?
