Arch kernel designation

How come the full kernel version isn't included in the arch kernel? Like when doing uname -r, it only shows 2.6.27-ARCH, and not what further revision of .27 it is. Would it be too hard to include that, so we could know whether it was 2.6.27.1, or 2.6.27.5, etc?

How come the full kernel version isn't included in the arch kernel?
As far as uname goes, so that /lib/modules/2.6.27-ARCH does not become...
/lib/modules/2.6.27.1-ARCH
/lib/modules/2.6.27.2-ARCH
/lib/modules/2.6.27.3-ARCH
/lib/modules/2.6.27.4-ARCH
/lib/modules/2.6.27.5-ARCH
It means that the NVIDIA, VirtualBox etc modules always stay in the same place so if their bindings arent changed (unusual in a kernel fix update) then the modules just keep on working rather than needing a new version of them for every kernel update.
Just shows pacman > uname

[SOLVED] Arch Kernel causes problems

Since my very first time installing Arch, i was getting some errors like
Cannot parse block device ids for /dev/sdb2
Cannot find root device /dev/sdb2
and eventually i had found a work-around, by taking the kernel and initramfs files (both 2.6.25.20-114) from another Linux, and also the corresponding modules directory. (Works perfect, using Firefox on it at the moment.)
Now i want to upgrade my kernel eventually (don't have to actually, but i want to, and the problem should not happen anyway) and still, after retrieving the new kernel through pacman (creating the vmlinuz26 and kernel26.img files in /boot, as well as the modules directory) and using it, i get the SAME problem.
The Arch kernels just won't work for me...
Does anyone have an idea what it could be?
(And is there any way to copy the exact error-output i get while trying to boot?)
Thanks.

Why no bootsplash or fbsplash in arch kernel?

I'm not begging for a feature, if I wanted it I'd compile it myself, but I was genuinely wondering, why no bootsplash or fbsplash patches applied to the default arch kernel?
If a splash patch is included in the kernel, it doesn't have to be used if the user doesn't want, right? And bootsplash has been around for quite some time, and every time I used it it felt like stable software (as in, I had no problems with it). Now I never tried fbsplash, but why not include one of them?
I'm sure there's a good reason not to have arch patch the default kernel with either patch, I was just wondering what it is.

Amazingly, people use Arch on their laptops too.
IE Me, So I am constantly rebooting, software suspend isnt worth the effort when I boot up in under a minute.
bootsplash is also nice when you want to do some console based work, or operate entirely from the console.
As has been said, bootsplash isnt included because of Arch's keep it simple philosophy, developers only patch the kernel with what they need, no more.
Another reason, could well be that the patches are not well maintained, take a look at bootsplash.org, no recent kernels have patches. Sure bootsplash.de have them, but they always arent out until even a few weeks after the kernel.
And finally, compiling the kernel with either bootsplash or fbsplash would stop a user from having a choice between the two.

Instead, I switched to catalyst-hook (I used catalyst) and upgraded to kernel 3.11.4, the latest version of xorg (there was a new one), gnome 3.10 and the module compiled perfectly, so now everything works on my system
You right, but you know... I have a lot projects in queue and not have time to search and test evertying
But, now... catalyst has installed successfully, but, I think isn't working 100%, because, when I click (for example), in a Google Chrome tab, and move to left/right, all tabs disappear or are blurry.
Anyway, thanks.

TRIM command (as it applies to SSD) and the vanilla arch kernel

According to this wikipedia article, the TRIM command has been implemented in Linux since kernel version 2.6.28. I'm wondering if the vanilla Arch kernel (x86_64) has support for this compiled in and if so which module would one need to modprobe to use it?
Thanks!

graysky wrote:hmmmm... is NOMMU_INITIAL_TRIM_EXCESS the so-called "TRIM" support in the kernel?
I don't think so, that seems to be memory (ram) related (NOMMU.... MMU is related to memory access as far as I know).
All I could find with a quick google search were a few posts saying there are submitted patches and some scripts .... nothing too certain.
As always things seem to be going at the windows development speed instead of the pace technology could go, also it seems that the spec for the trim command is/was still being finalized.

Glibc update and /lib/modules/extramodules-3.4-ARCH/kernel/oss/ folde

so I made the steps mentioned here: https://wiki.archlinux.org/index.php/De … iki:usrlib
after doing "find /lib -exec pacman -Qo -- '{}' \+" I see I have a lot of stuff in "/lib/modules/extramodules-3.4-ARCH/kernel/oss/" folder, BUT I don't even have oss installed. So I wonder, why are they there, and if I can delete this folder?

Like Capoeira, I also have some files left in my /lib folder:

If a file is not owned by any package, as is the case for all files in this list (except for the ones owned by glibc), can I then just remove it? I might make a backup of those files just to be sure, but it doesn't make sense to just copy this stuff to /usr/lib.

I just wanted to know what some of the differences between the main stable 2.6 kernel and Arch's 2.6 kernel are. I'm not a fan of compiling kernels, so I'd like to know what decisions are made for the default kernel.
Let me be more specific;
1. linux-2.6.26.1/Documentation/java.txt: apparently, native support for java binaries is planned for the kernel. Will this be reflected in Arch's kernel as well?
2. Besides x86, what architectures are supported by the Arch kernel (linux-2.6.26.1/arch)?
3. Does the Arch kernel support virtualization by default?
4. Which drivers (if any) are excluded from Arch's kernel (linux-2.6.26.1/drivers)? (If any, why?)
5. Which filesystems are supported by the Arch kernel (linux-2.6.26.1/fs)? In the install, there are only 5 filesystems available so I'm guessing it's just those 5?
--- And any other major differences that are worth noting.
Thank you for reading!

there is a bug with xen in kernels newer then 2.6.18.
arch's kernel is as vanilla as the stable release is from what I gather. Other then a few patches and some config changes. Arch tries to stay as close to vanilla as possible with all it's packages. just do a diff between the two configs.

Arch kernel with PAE

I asked some times ago about including PAE (HIGHMEM) in the offical Arch Kernel in x86 and i was said no beceause it is slower and when i want more than 4gb memory i should use x86_64
now i seen. 32bit is not slower with PAE. Only the stuff over 3GB is slower than with 64bit.
So the argoument PAE is slower is nonsense beceause the memory which is accessed slower is not existing without PAE so we have the choose between
No Memory over 3GB
Slow Memory over 3GB or lemme say not fast as it can be
the first 3GB are the same speed with and without PAE so maybe we should re-think about this

That is very strange (and dare I say wrong) given how PAE works... it is not as if it uses it memory mapping only when needing greater than 3Gb of memory, it needs to use it all the time: http://en.wikipedia.org/wiki/Physical_Address_Extension
And here is the only real attempt at benchmarks I have seen. Although it is a bit old...

compile, the PAE penalty works out to be around a 1% performance hit on Red
Hat's test boxes. Testing with various other workload mixes has given performance
hits ranging from 0% to 10%.
wow its really a bit old and i dont know how it was tested
is there a really good way to benchmark it?
i just written a bash skript which pumped up the memory and taked the time until it needed to reach 3,8GB

Suspend removed form arch kernel ? [solved]

I don't know why Software suspend was removed from default arch kernel.
Can it be re-enable ?
I have recompiled arch kernel with addind this options :
CONFIG_PM=y
# CONFIG_PM_DEBUG is not set
CONFIG_SOFTWARE_SUSPEND=y
CONFIG_PM_STD_PARTITION="/dev/hdx"
but there is no /sys/power/disk or /sys/power/mem on my system
(it was working with 2.6.13 arch kernel)
did I missed something ?

ok, I think that initrd is the problem.
http://wiki.archlinux.org/index.php/Initrd
I have found some scripts but it's only for swsusp2
http://wiki.suspend2.net/DistroAndHardw … bianInitrd
Anybody knows how to activate vanilla swsuspend1 on arch ?

Cannot compile ARCH kernel

Hi there!
I'm new to AL, so this might also be a newbie question, but noone could help me so far.
to get to the point, everytime i try to compile an ARCH kernel with:
"make && make modules modules_install"
i get an error concerning the Makefile:
[root@portdemonia linux]# make && make modules modules_install
CHK include/linux/version.h
CHK include/asm-i386/asm_offsets.h
scripts/Makefile.build:13: init/Makefile: No such file or directory
make[1]: *** No rule to make target `init/Makefile'. Stop.
make: *** [init] Error 2
I'd be very glad if anyone could help me out there

@craw
Believe me, you don't want to build the kernel the old fashioned way.
It's messy, really messy (IMO).
"pacman -S kernel26" grabs the latest kernel (as the description says: kernel and modules) binaries.
I suggest you try using ABS.
As root run "abs".
It will grab the latest PKGBUILDs & additional files for all the packages from the repositories.
1, go to "/var/abs/kernels".
2. copy "kernel26" directory to /var/abs/local/kernel26-myversion (or whatever you want to call it).
3. Modify the PKGBUILD inside: replace "yes "" | make config" line to be more precise with something within your likes, such as "make xconfig"/"make menuconfig" or even "make oldconfig", to use as base the ArchLinux "config" file there.
4. save the PKGBUILD
5. modify the "config" file in that directory, this line to be more precise: CONFIG_LOCALVERSION="-ARCH" / replace ARCH with something else (I don't know how effective this is when you start a new config)
6. run "makepkg" in that directory
7. during the build process, you'll be shown the interface to choose what/how to install
8. in the end you'll have a brand new ArchLinux package with your kernel. You'll be able to install it using "pacman -A whatever_your_pkg_is_named.pkg.tar.gz"
This way, if you choose to remove it/update it, your system will stay clean because the files in the pkg are kept in pacman's DB.
But.. the best thing is to read about ABS first. Good luck.
Enjoy afterwards.

Is the standard Arch kernel preemtible?

Hi,
in the process of reporting a bug I posted a uname -a which included the text PREEMPT and was then asked if I was "running with CONFIG_PREEMPT (Preemptible Kernel)". I am using the standard Arch kernel, is it a preemtible kernel?
Thanks, Jamie

[dieter@gibran ~]$ zgrep CONFIG_PREEMPT /proc/config.gz
CONFIG_PREEMPT_NOTIFIERS=y
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
# CONFIG_PREEMPT_TRACER is not set
Next!

Can't boot standard Arch Kernel (root btrfs partition)

For a long time I using linux-mainline from AUR. Unfortunately Docker don't work on it. I tried to boot standard Arch kernel 3.17 from testing but i have got:
:: running early hook [udev]
Warning: /lib/modules/3.17.0-1-ARCH/modules.devname not found - ignoring
:: running hook [udev]
:: Triggering uevents..
Scanning for Btrfs filesystems
Waiting 10 seconds for device /dev/disk/by-uuid/(uuid)
ERROR: device 'UUID=(uuid)' not found. Skipping
ERROR: Unable to find root device 'UUID=(uuid)' .
I am using rEFInd to boot. This is config file of kernel:
"Boot with defaults" "root=UUID=3c5d33c2-1d2f-4c57-b226-ad7ecc51be00 rootfstype=btrfs rw"
"Boot to text mode" "root=UUID=3c5d33c2-1d2f-4c57-b226-ad7ecc51be00 rootfstype=btrfs rw systemd.unit=multi-user.target"
I tied to downgrade kernel to last stable version but it not helped.

I uncommented the testing repo and pacman -Syu. i tried downgrade to standard repo but it did not help. I have not used standard kernel for more then half year.

[SOLVED] Arch Kernel Configuration

Hi, I'd like to compile recompile the Kernel but I would like to know wich are the default configuration settings that the compiled kernel26 of the core repository has. I would like to tweak some things but starting from that configuration not from the defaul Kernel configuration found in www.kernel.org.
I would like to know it ABS could be used to do it, or if I can get a configuration file somewhere and use it with ABS.
Thank you very much.

Ok thank you very much! I've found the configuration within the ABS package. The I can edit it running make menuconfig (or the GUI configurator) and then save the edited file as config (in my case, if it was a x84_64 it would be config.x86_64.
I had to change the checksum for that file in the PKGBUILD file in order to it to work.
It's now compiling!
Another question... Does it uses the CFLAGS defined in /etc/makepkg.conf when compiling the Kernel? I hope so...
Once more, thank you very much for all!
You can also use the ABS PKGBUILD, and add the "make menuconfig" option to be able to change the -ARCH settings.... then when you press exit it will save (and use) your newly created .config.
# load configuration
make menuconfig
# build!
So it will load the default -ARCH generic setup and then you can modify to your hardware specs.

[solved] arch kernel freezes, how can I replace it with lts

the kernel freezes on almost every boot; I'm referring to the kernel installed and downloaded when I used the net install to install arch
how do I install the lts kernel ? maybe the lts won't freeze...

solved... I got rid of kernel freeze, or kernel hang, by appending the "acpi=off" parameter in grub
I have no idea what "acpi=off" does, but it's the olny solution I found that enables me to both install arch and use it...
Keep an eye on the battery meter, w/o acpi your computer might be using more power.
