Linux 2.4.15 is out; Linux 2.5.0 has also begun.

jbondjr writes: "It appears 2.4.15 is released. It's not quite updated on kernel.org's main page, but it is there if you dig through the tree. You can find 2.4.15 on one of your friendly Kernel.org Mirrors (note the 2.4.15 Changelog) From the 2.5 readme: "Linux-2.5.0 is exactly the same as 2.4.15, except for a version number change." So, enjoy the The 2.5 Tree

Preemptible kernel

[ThatComputerGuy]

Don't forget the Preemptible Kernel [tech9.net] patch. This will reduce latencies and overall make a desktop machine feel snappier.

From what I hear, however, it's not recommended for servers where bandwidth is more important. But then again, you wouldn't be putting a bleeding edge kernel on there anyway, now would you?

Re:Turkey!

[chabotc]

Ps, if anyone else, like me, likes his /lib/modules tree without holidays that are not celibrated here in europe; or is a religious vegitarian, simply edit the toplevel Makefile and remove the 'extraversion' (-greased-turkey) from it. Then you will have a 'plain' 2.4.15 ;-)

Re:patch for XFree86 4.0.3 dri?

[leine]

Linus has a little package in the v2.4 directory. It is called drm-4.0.x.tar.gz. You can use it to get DRM for XFreee86 4.0.x.

Re:Preemptible kernel

[chabotc]

Also, as we speak, the rml preempt patches for 2.4.15 have not yet been released, and the older ones (2.4.15-pre7) do not apply cleanly to the 2.4.15 tree. If you want to use that patch, wait a few hours/days. (they are very much worth using on a interactive desktop machine).

Re:Todo list?

[Dr.Dubious DDQ]

Don't forget the possibilities of (in no particular order):

• ALSA sound
• MOSIX
• BTTV2/V4L2

Use the mirrors

[jbondjr]

Looks like kernel.org has updated their main page and their 100Mbps connection looks pretty maxed.

http://www.kernel.org/mirrors/

Sorry, seldom post, so don't know how to make a link on /. Also surprised my first submission got accepted :)

ext3

[ma2tias]

Now, for the people who use ext3:
You will not need to download ac/ext3 patches anymore to get your journaling running.

Re:So who else is downloading 2.5

[krorvik]

Thought about it, but then I realized that I would have to go *back* to 2.4.16 to keep on the stable side. So I'll just stick with 2.4.15 for now ;)

how to make a link Re:Use the mirrors

[leuk_he]

just code html to make a link. you should type:

<a href="http://www.kernel.org/mirrors/">http://www.k ernel.org/mirrors/</a>

This works in html formatted <B> and </B> plain old text. (i think code as well).

just a tip.

Re:Todo list?

[chabotc]

To get a good feel for what the posible new cool things will be in the 2.5 kernel, check out the video / subscripts from the 2.5 kernel summit a while back. They mention

Raw access to block devices (DB work)

SCTP (nice network tricks)

Block layer redesign (scsi, ide, etc)

High performance file systems (xfs, jfs, etc)

Re-worked network driver API

Hot-Plug Devices (pci/pcmcia)

Kernel build system

Intergration of some NSA secure linux idea's (mandatory ACL's, etc)

Async-IO addons (non posix conforment)

ACPI / Power management (needed for hot plug?)
And a lot of other topics. 'Specialy make sure to check out the video's. They provide some nice insights into the wo the file systems (xfs, etc), raw access to block devices (oracle was hot on this i think),rld of kernel hero's ;-)

check out this link to the lwn article [lwn.net] for more details, descriptions and links.

DON'T open the link in the above post if you value your lunch.

Loopback device fixed..and new pcmcia-cs 3.1.29

[buserror]

For some reason I couldn't get the loopback block device module building in 2.4.14 on my laptop (depmod chocked on undefined symbols)

works again in 2.4.15

There is also a new (at last! almost 4 months since .29) 3.1.30 pcmcia-cs package there [sourceforge.net]

Re:hard packed versions

[w00d00]

since the name is different, the overall entropy is different. IMHO the packaged size then depends on the algorithm..
just my .02

Unprofessionalism has a price

[Sits]

If you use make bzlilo then you will end up with the error:

Fatal: Label "2415-greased-turkey" is too long

While it's easy enough to fix (edit lilo.conf), I bet this is going to cause problems for someone.

Re:Preemptible kernel

[areguly]

I use it flawlessy for a few weeks now. A few lines are pushed down in the source, but that doesn't hurd. I recommend it.

I apply first xfs then preempt patch.

2.5 not fully open yet

[kanelephant]

It will probably be at least a week until 2.5 really gets moving. Linus on the lkml

...when I release 2.4.15, I'll at the same time release a 2.5.0 that is identical except for version number (that makes synchronization easier later on). And I'll probably _not_ start accepting all the big waiting patches immediately, I'd rather wait for at least a week or two to see that there aren't any other issues.

It's much easier doing some of the IO patches in particular knowing that the base you start out from is stable.

Re:hard packed versions

[42forty-two42]

a: the subversion joke in 2.4.15 b: compression is very picky. A change of one byte makes a big difference.

Re:Preemptible kernel

[_Knots]

FYI, the patch *makes* it a compile option under "Processor Type and Features." It's a Y/N called "Preemptible Kernel."
