Linux 2.6.22 Kernel Released

[harry]

Updated version of Linux Kernal has been released, this new 2.6.22 kernel have some good features such as SLUB allocator which replaces the slab allocator, a new wireless stack, a new Firewire stack, and support for the Blackfin architecture which will help webmasters.

So what's a SLUB allocator (and why would I want a SLUB that would subsequently need allocating) and why will the Blackfin architecture help Webmasters?

SLUB is all about kernel's memory management which is more advance then slab allocator.
Using SLUB allocator you can save huge memory if your kernal is running on a huge farm of processors (may have thousands of processor ) which was a big overhead for slab allocation.

ah that will be handy for my huge processor farm then and what about Blackfin architecture - why will that be useful for Webmasters?

How many processor do you have in your farm now

what about Blackfin architecture - why will that be useful for Webmasters?

Blackfin architecture enables you to design a system specifically to meet
large computational demands as required by multi-format audio, video, voice and image processing; multi-mode baseband and packet processing; control processing; and real-time security.
These interfaces are ideally designed in a way, that they can be operated with very low or none overhead impact to the processor core, leaving enough CPU time for running the OS and processing the incoming or outgoing data.

[ This post was just for making LINUX administrator aware of this new release who works on kernal....]

lol - just enjoying watching you squirm Harry. Blackfin is a processor that is used in some embedded applications, you would have to be a pretty strange Webmaster to get much value out of it and I don't suppose the fact that you can now run Linux on it is going to impact on many people.

Interesting in a uber-geek kind of way though and it did make me read some Linux stuff on memory allocation...which made me remember why I never want to do any very low level application programming

That's very true.... " Blackfin is a processor that is used in some embedded applications " but now we can implement such Blackfin architecture on Linux servers which are serving huge audio, video and image processing requests. This architecture will
help in lowering the load on CPU and will response to queries more faster;

This new improvement in kernel will help sites like YouTube, flickr, social bookmarking sites, video-images sharing sites and other sites which require huge processing of data at server side.

Oh really, you embarrassed me Kev.... but was happy to answer you and do some research for you

Also Slub would be obviously better than slab, there are also Source-level changes what I observed, that you can track through here; git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=summary
Just wondering can 2.6.22 run on iPhone?

[kev woodman]

Nothing that does not come direct from Apple runs on the iPhone does it? I thought that it was competely locked out to outside devs?

[paul]

I would wait to learn from ultimate users experience those put their hand first.

[kev woodman]

Actually I should clarify my earlier comment - I think that anything that runs inside Safari will run on the iPhone but there is no JVM so no way to develop stand alone apps.
