There's some NFSv3 and other stuff pending, but those who have pending stuff should all know who they are, and for the rest it's just time to say nice try, see you in 2.5.x. The pre-2.4.x series will probably go on for a while, but these are the 'bug fixes only' trees. These are also the 'I hope a lot of people test them' trees, because without testing we'll never get to the eventual goal, which is a good and stable 2.4.x in the reasonably near future.

  • How stable is the current devel tree? 2.3.41 was fine for me... but later kernels either failed to compile or crashed on boot. Are we going to see a long pre- cycle, or is it relatively debugged already?
  • Reiser? Why not Ext3? I do understand that Ext3 is not better then Ext2 with journal, but still...

    BTW, did they move to DevFS? Or still the annoying major/minor thingy?
  • Devfs is in, but still experimental IIRC.
  • Anyone have any pointers or web sites on getting these pre2.4 kernels up and running? I'm going to try to get it running in Slackware 7. Thankfully, I have VMWare up and running and registered...

    From the looks of Linus's comments, it's only a move from the (currently very slushy) pretty-much-anything-goes-if-it-compiles-feature freeze to a (slightly more frozen) already-announced-but-not-yet-fully-included-featu re freeze+bugfix stage.

  • I don't believe ReiserFS is included (and neither are ext3 and jfs?), and if it was, as an AC pointed out below, it would be pretty hard to take a screenshot, a benchmark or a time to reboot comparison would be more accurate.
  • Anyone have any information on how this will integrate with Apache, and any news on a multi-threaded version?

    f you can't program you have no business using a pre-release kernel!

    Yes and no. Remember that even most kernel hackers aren't familiar with every part of the kernel and can't fix everything that goes wrong. There are kernels that should legitimately be avoided by everybody, and then there are those that pretty much just work. Linus is now aiming explicitly at the latter; the kernels near the end of a development cycle need to get used so that bugs can be found and fixed. With this in mind, it's time for everyone to start using 2.3/2.4pre on all the non-production machines you can find. Bugs won't get fixed if nobody is using these kernels.

    In answer to the original question, the best places to look are the Documentation/Changes file, which describes what software you need to build and successfully run the latest kernel, and the mailing list, which is archived at www.kernelnotes.org and other places.

  • In what way will devfs remove the need for the major/minor scheme? As far as I know, devfs only provides a major cleanup of the namespace bloat in /dev. Otherwise, drivers are still referenced by major and minor numbers through the vfs layer.
  • Poor fools. Windows is already at version 2000. Just more proof that this "Open Sores" crap will never make it in the real world. Come and use a real OS with a real version number sometime.
  • As far as I remember, getting 2.4 to run with say RH 6.1 is no problem what so ever. Just make dep ... and install with your favorite method. A few apps will be hit with quite substantial modifications of the layout in /proc but usually that will not prevent you from getting the system up and running.
    Changing to 2.4 from 2.2 is much easier compared to the transition from 2.0 to 2.2.
    If you want to try out devfs, read the docs and install devfsd.
  • If you do not know how to "get these pre2.4 kernels up and running" you should not be doing it. For those that say there needs to be as many people running these as possible, I say: if a person can't even figure out how to install the kernel, how much help are they going to be in isolating and helpfully reporting bugs?

    1.1.13 - May 22 1994 (cant find a 1.1.0 so I'm guessing its about mid-april or there abouts)
    1.1.95 - Mar 1 1995

    2.3.0 -- May 11 1999

    So we've run about the typical time elapsed between dev kernel versions but the current kernel version is half that of normal so it makes me wonder if we're ready yet.

  • The irq,dma,address is now either probed by the kernel or is given as a option to the kernel at boottime. read the help on the soundblaster option for more info.

  • I thought that was already done with oh-some-MS-supporting company (I can look up the name if somebody actualy cares), but not on open source basis :(.

    As far as experimental goes, you should have seen the IE (hooked with MS implementation of COM/DCOM services) on some-NIX boxes chewing up resources faster than 1k memory leak in 1-ms timer code (and that's a lot).

    I wasn't experimenting with any of the 2.3.x series kernels (last time I fiddled there was with 2.1.x series), but if you take open source definition of experimental (remember experimental ELF binary support) it will work on this kernel and not on next, and work again on next and so on... But the main point is that it WILL WORK! AND I LOVE IT!

    It might be on anyones checklist (I don't care about IT drones anyway, since I'm freelancer), but it'll do magic for ME AS A PROGRAMMER. Like (probably, I hope I'm wrong) most ppl. I make my day to day buck with MS products (let's face it: MS sells no matter what you say or do -- fortunately same goes for linux/GNU/... :)). The way it'll help me because I will be able to propose more cost efficient business solutions to potential customers. If I can take their already bought MS transaction server and use it on business tier, put linux on presentation (Web) tier and connect them without much hassle (DCOM comes as a glue) that's what I LIKE. Options for this kind of close integration will be endless.

    As far as dependencies go, linux already has orbit which provides component services and things depend on it. The point is no things depend on it. MS might like it a lot, people around me like it a lot (personally I hate it a lot), but if you take away (D)COM from WinNT platform you basically can't even send 'A' to ASCII printer (Win95 comes off beter by being built on top of DOS and gives you option of doing "echo A > LPT1:" but that's where it ends. You might find it a bit tricky [but not impossible] to send FF that would eject the page). I can strip linux (ANY linux) to core and put it on almost any CPU gifted with reasonable amount of RAM.

    Bottom line is that this will give my kind of comunity (day to day people that happen to live off computers) power of choice and this is what's all about! GNU is about choice, Linux is about choice, open source is about choice. I like having choices, options, brain food and http://www.userfriendly.org/! If 2.4.x kernel will give me that or any other choise to think about, I'll be first in line to grab it from nearest mirror!

    It is the 2.3.51 kernel running in a set of Linux processes. No need for a spare machine, and it doesn't have access to your hardware or filesystems, so it's less worrisome than a native kernel.

  • I don't know about ReiserFS and ext3 file systems, but jfs (if you're referring to IBM's jfs) is at such stage that it might appear in 2.5.x series, but probably not at the start of the cycle. Last time I checked the porting page, they were just able to read directories, no chances of even reading files in very-close-future.

    It was even mentioned that jfs will cause some major changes deep in kernel and that will probably make it candidate for 2.7.x series more likely than 2.5.x.
  • I have an old 486SX laptop that I use as a terminal to my main Linux box over an ethernet link. It runs mulinux using kernel 2.0something and drives a PCMCIA ethernet card with no problems (well it did until my 12 month old son dropped it on the floor, but that's another story.)

    There should be PCMCIA support in 2.2 kernels, unless it's a winmodem (i think most laptop modems are?), which isn't suported by anything except Windows AFAIK.
  • Well, the 2.3.x series has "pre-patch"es. So each point release in the 2.3.x series is probably equivalent to about two point releases on the earlier unstable release cycles.
  • It is, because linus said so.

    At the begining of this cycle it was made very clear, in lots of mediums from /. to the 'normal' press that the developement cycle was too long. Less features were added to the kernel, and some that are 'almost' ready that would have held up 2.4 just diddnt get in. This will give everybody some new feature now, and make the upgrade less painful.

I (for nice example) used to be C/C++ freak programmer (I still prefer C for personal stuff, that I try to write cross platform) and hated all those VB/Delphi/Builder "babies". With time I was forced to use other programming environments and languages and I found out each and every one of them has distinct advantages and handicaps (you just don't get REAL caffeine by drinking de-caf, no matter if you're in NYC or in Calcuta).

    At the moment I'm on project involving MS backends, MS tools, MS components, ... basically all MS. It's just the policy of customer to use MS only stuff. I can't go to the customer and say that all his systems are piece of crap, since I've been working with them for some 8 years now, I can't tell him to trash all his existing solutions so I can bring in one open source solution, I can't make a product that won't interoperate with existing software. That is privilege of MSs, IBMs, Suns and others.

    What I learned is that nothing can be done by hitting your head against the wall. Yes, it might be rotten publicity, but are we employing PR people to take care of our "faces" (used in japanese sense of the word) or are we trying to do something for ourselves! -- Exclamation, not question mark.

    I think we're trying to do something for ourselves. KDE has it's licencing quirks, but it's still popular. It obviously didn't die of bad publicity. Gnome has no licencing quirks and it's popular. What's the catch... I can have Corba, I can have DCOM, I can have my own protocols running around wild... The point is that user doesn't care what does it run on as long it runs well. COM, DCOM, Corba, ... are just tools to achieve that. Nothing more. No bad PR. If MS doesn't want to comunicate with other solutions, it's their problem. Right now it's my problem as well... If DCOM/Linux takes off, it won't be my problem any more [I still like MS DevStudio though... No Linux viable counterpart yet :(].

    The biggest non-speed related advantage is netfilter (a replacement for ipchains that's quite a bit more efficient). Everything else is for performace, scaleability, or both.

    On the memory front, it's a mixed bag between taking up less memory or taking up more. The kernel marks more memory as unusable in 2.3 than 2.2 (dmesg indicates that that memory is where ACPI sits, even though I have ACPI disabled on the motherboard).

    However, it certainly swaps less, even after several days of use.

    WRT memory consider it to be about the same as 2.2.x.

    So 2.4's firewall code will transparently work both like 2.2 and like 2.0 did.

    Yes--If. That is if you have installed Netfilter and configured it for backwards compatibility. Trying to run ipchains rules on 2.3.xx kernels will just return messages like "The use of Ipchains is not supported by this kernel." Enabling packet filtering (which is the replacement for ipchains according to the kernel menuconfig help file) isn't sufficient to allow ipchains to work transparently. Or it wasn't, ca. 2.3.42

    I am just a user out there in TVLand, and I've been kind of hoping/petitioning certain sites like Linux.com to to run an article on transitioning from 2.2 ->2.4::ipchains -> netfilter+iptables. It would make a great newbie HOWTO for someone who's smarter than me. Which is an open invitation for lots of you geeks out there to show us how brilliant you are! So far i've just gotten polite refusals from the sites I've contacted.

    Will the need to have firewalling for 2.3xx overcome my innate laziness and stupidity before some perspicacious, valiant soul writes a guide for the netfilter-perplexed? Lord I hope not. That shit be hard to read you know what I'm sayin'?. Will I be hacked meanwhile? (If you want know what it's like to be buggered with Comet cleanser lube, just try it.)

  • In the documentation on Corel's Linux website, they mention that "UDMA66 support" will not be available until the "2.4 kernel."

    Does anyone know if this means Linux 2.4 will be the first version with built-in support for Ultra DMA66 hard drives and (hopefully) up to four IDE buses like on the ABIT BE-6/BP-6/BX-6 motherboards?

    C) I love our closed spec obfuscated source buddy nVidia still. I'm a pretty happy camper. My card runs fast as hell, and I have no religious attachment to Linux/Be/etc.
    D) I think you missed the subtlety abou the DRI thing. They only DRI compenent that goes in the kernel is the DRI kernel driver. That is accelerator non-specific. Thus it will work with any card, it is just a system for the DRI driver to communicate through the kernel. It is a symantical thing, no DRI support for a particular card acutally goes in the kernel, it is loaded by the X server which uses the hardware independant kernel driver to talk to the hardware. I really don't care if Linux has no place on your drive. If you aren't willing to use a GeForce just because it doesn't run on your precious Linux, thats your problem. Don't, however, blame nVidia for it. Their product kicks ass. Have you ever run 3D Studio on a GeForce? You'd think you were on an SGI! They will have accel. OpenGL on Linux soon. If you have some problem with it being closed source and propriotry, fine. But I'm just sitting here waiting for Redhat 7 and nVidia's super tweeked OpenGL support. (BTW nVidia's drivers won't use DRI.)

    2.4 will be the first stable release with UDMA66 support included with the source. 2.3.x (I don't know what the earliest version that had it was) also has it included. There is also a patch [kernel.org] for 2.2.x. Make sure to check the documentation there.

    As for four IDE buses, yes, they will be supported. I've used both 2.2.14+patch and the 2.3.x with a Promise UDMA66 add-in controller along with the 2 controllers on my motherboard with no problems. The ABIT motherboards are also supported by the drivers.

  • So we've run about the typical time elapsed between dev kernel versions but the current kernel version is half that of normal so it makes me wonder if we're ready yet.
    Yes.

    Linus set out to only include a limited set of stuff in the new kernel, so that that thumping huge 27-month gap wouldn't happen again. The fact that there have only been 51 blockpoints is a reflection of the decreased new-feature count. As it is, he'd have liked to have been done by December, but you know how things go... as it is we're getting one a year and being lucky to do so, at this rate.

  • There's a UDMA patch available for the 2.2 kernels. It's linked to in the UDMA mini-howto (see ldp.org). It's basically the same as what's going into 2.4 (aka, in 2.3 right now). However, I haven't had any luck getting it to work on my ABIT BE6.

  • They've had that for a while now. If you look in the Makefile, you'll see that `uname -r`=2.3 gets mapped to the 2.4 defines, so for a while there I was compiling a module for a 2.4 kernel! I went back to the stable because I had some very serious filesystem corruption (like stuff in /lib ... ick!), giving me a good excuse to change distros to Debian.

    On the subject of sound, I noticed that Debian does not have a save/load of sound settings (volume in particular) like Red Hat and company do. So I wrote my own little script to do that. If you want it, e-mail me, but it's really very simple so you could probably write it yourself. Another Debian quirk -- ahem, feature -- is that the sound module is not loaded automatically like in RH, but if you put it in /etc/modules with all other modules you want loaded at boot time, there it will be. If you have to give the module any parameters, you can do it there or put them in /etc/modutils/$modulename (I have in ./ne, 'options ne io=0x200', to match my isapnp setting it to io 0x200, for example).

  • If a person cannot figure out how to read and assimiliate the abundance of information regarding the downloading, configuration, and installation of either the Stable or Development kernels, what I said above still applies.

  • Actually, it does :)

    The package you are after is called "gom", and once you manage to configure it properly, it will load/save mixer settings on reboot.

    I had it working with my old SB16, but since i upgraded to an sb-live i havent been bothered getting the module "installed" correctly. (ie i insmod -f /usr/local/src/emu10k/emu10k.o every reboot by hand..)

    On that subject... anyone know the status of an SB-Live driver ever being included in the kernel? Its no longer a binary only module, and I know Alan (cox) has been working on the driver a bit... Its just a pain to recompile/re-download it every time you upgrade kernels...

    I don't see why a humanities journal shouldn't have reviewers, if only for the simple reason that it'd be silly to pull the top twelve papers off the incoming pile and call it a journal. Maybe the reviewers wouldn't necessarily play the same "objective" role that they do in a more technical journal, but no one that I know of (except the postmodernists, which was the point of Sokal's stunt) is making any such pretenses to "objectivity".

  • The trouble with that plan is that the whole reason to bang on these pre-release kernels is so that faults can be caught and squashed when the real one is released.

    If you tried to log a fault with a user-mode kernel you'd not get very far on the lkml. Worse, you're going to cause confusion and dilute the testing process.

    The only benefit would be if you were an absolute testing god, and could weed implementation bugs out from the inherant kernel bugs, do some fancy debugging from the working system to the broken one and send the lkml a proper fault analysis and patched code. THEN I'd be impressed.
  • Try adding append="parport=0x378,7" at the start of your /etc/lilo.conf. Change the values appropriately.

  • This question does not make any sence. 2.3 is a development tree (much like 2.1). 2.2 and 2.4 are the stable trees.

    By convention, Linux kernels with the odd minor number (as in 2.1, 2.3, etc.) are development kernels (read: not stable, constantly changing). Kernels with even minor number (as in 2.0, 2.2, etc.) are stable (only changed due to bug fixes). So the "stable 2.3" is 2.4.

  • There is a reason Matrox, ati and 3dfx have taken the pledge to be open. They are either tiny in the case of Matrox, or dying in the case of ATI and 3Dfx. A market leader has no real incentive to support Linux until it becomes big. And when it does, they still won't need to open the source. Corperate users really don't have the time/resources to hack a graphics driver. Second, I'm pretty sure the nVida GL will not use DRI. They made a statement that DRI was not exactly appropriate for their graphics pipelines. Most likely, it wil just be a patch to the kernel. I don't play Quake that often. I do, however, have a problem with not using my hardware to its 100% just because some OSS guys want their precious, divinly inspired idea to succeed. Hey, there is nothing ethically ambigious about my point. I could care less if their wasn't a single Open Source driver on Linux. You may, and I have nothing against that. I just want my hardware to work, and work at 100%.
  • Just because it's a pre does not mean that it is stable at all. It merely means that there will be no more non-pending features added. In other words, the focus will be on making it stable, rather than on adding new features. Consequently, this pre/2.3.51 should not be expected to be any more stable than 2.3.50 or any other 2.3.x It is merely the beginning of making the kernel stable for 2.4

    Chris Hagar
  • All minor-odd numbered kernels are designated Development, a tree where new features can be added to the kernel without sacrificing stability. All minor-even numbered kernels are designated Stable. Consequently, by the very definition of the numbering of Linux kernel's, a 2.3.x kernel cannot be Stable.

    Regardless, the very process by which one would make the 2.3 kernel stable would produce a kernel for the 2.4 kernel tree, and consequently be a Stable kernel.

    If all you want is USB support, there are patches to add USB support to the current Stable kernel, if you just look around for them.

    Chris Hagar

  • This definitely is an interesting phenomenon, but I don't think it indicates that the new kernel might not be ready to see the light of day. If you think back to who was using Linux in 1994, and who's using it now, or, rather, who was aware of it then and now, there is significantly increased awareness now. I think the shortened development time is due to more eyeballs.

  • 1. All changes to /etc/conf.modules get wiped out when you do a update-modules (some package installations may do that, possibly the kerenel package; I don't know). Make all local changes in /etc/modutils/(whatever file is appropriate). It does what is equivalent to a run-parts in that directory, except it filters by architecture. 2. Depmod should handle all module dependancies, and when modprobe comes and loads the sound module, it'll see the dependancy, and automagically load the depended-on module first. Instead, in /etc/modutils/aliases: alias sound emu10k1 and in /etc/modules (this does not get update-modules-ized AFAIK): sound And you should be set. 3.
