Latest Linux 3.17 kernel with OpenEmbedded/Yocto

I'm currently building my Linux system using the OpenEmbedded linux-xlnx_3.14 recipe in the meta-xilinx layer.
I've noticed that SDK 2014.4 produces a somewhat different device tree to previous versions, which I assume has to do with the newer 2014.4 now using kernel version 3.17 instead of 3.14.
1. What is the closest recipe that PetaLinux 2014.4 is based off?
The figure 1 here seems to show meta-xilinx and PetaLinux draw from the same sources, but PetaLinux isn't exactly derived directly from meta-xilinx recipes: http://www.wiki.xilinx.com/Linux
These are the current list of kernel recipes:
http://git.yoctoproject.org/cgit/cgit.cgi/meta-xilinx/tree/recipes-kernel/linux
2. When might there be a linux-xlnx_3.17 recipe?
3. Is the linux-yocto_3.17 recipe good enough to try instead if I want the 3.17 kernel? What are the differences between linux-xlnx and linux-yocto practically speaking?

For question 3, I've found this mailing list message to be useful:
https://lists.yoctoproject.org/pipermail/meta-xilinx/2015-January/000896.html
Basically, linux-xlnx includes some useful/necessary Zynq drivers, depending on your needs. The list of ones that are and aren't included are here:
http://www.wiki.xilinx.com/Linux+Drivers
Also, this message and subsequent messages are about the future intention of the kernel recipes:
https://lists.yoctoproject.org/pipermail/meta-xilinx/2015-March/000927.html
They are intending to have just about everything that is used by the majority in the mainline linux-yocto kernel, so that linux-xlnx is only for testing development things. Kernel 3.19 and onwards has more Zynq drivers included towards this goal. So to partially answer question 2, it seems there may not be a linux-xlnx-3.17, but either a mainline linux-yocto_3.19+ or linux-xlnx-dev kind of thing that follows the latest.

UEFI boot problems with Linux 3.7 kernels

According to this thread in the Arch Linux forums, some people are having problems booting some versions of the Linux 3.7 kernel. Here are the numbers:
3.7.3 works for some, but not others
3.7.4 works for some, but not others
3.7.5 works
3.7.6 does not
3.7.7 works
3.7.8 does not
The problem occurs with both the Gummiboot and rEFInd boot managers, and has so far only been reported on Lenovo hardware. I have a ThinkPad W530, and can confirm that on Gummiboot, 3.7.6 does not work, whereas 3.7.5 and 3.7.7 does work. It looks like a Lenovo-related issue to me. It has only been reported on Arch Linux as far as I know. Has anyone else encountered this problem?

Thanks for your reply. Yes, the cursor did blink in the top left corner.
I gather from your comments that, if I install a new HD, I will be able to re-install the Windows 7 32-bit O/S from the Product Recovery DVD GMR410014EN0, which was supplied by Toshiba with the laptop and it would also follow, if that is true, that I would be able to Format (Boot n' Nuke) the existing HD and re-install the O/S onto it before I get my friend to lay out cash for a new HD.
I would appreciate your confirmation that the above conclusions are correct as I was under the, hopefully incorrect, impression that the Recovery Disk could only be used to repair an existing system. I have the Microsoft licence number as it is printed on the bottom of my friends machine.
Thanks for your time and I look forward to hearing from you.

Latest SO Patch for Linux (120184-14) fails with postgresql plugin

Hi,
the latest staroffice patch for Linux no longer works with the postgresql extension postgresql-sdbc-0.7.5. It can read tables but will not write back any modifications. The failure message is something about some routine not being implemented. I'm afraid I needed it in a hurry, so I reverted to the previous patch (120184-12).
My system is opensuse 10.3 running on an x86/64-it machine. uname -a gives
Linux hostname 2.6.22.17-0.1-default #1 SMP 2008/02/10 20:01:04 UTC x86_64 x86_64 x86_64 GNU/Linux
Does any body know of another convenient way of hooking SO up to postgresql?
Regards,
Charles

Hi dcminter,
your right, sorry, this isn't a Java question. I followed a link from Suns StarOffice page and assumed this was a purely SO forum. I've just noticed the tabs on the forum window. There is a separate section for 'desktop'. I'll repost there.
Regards,
Charles

How jvm threads works on new Linux 2.6 scheduler with SMP kernell

Hi,
i'm using Sun JDK Java HotSpot(TM) Server VM (build 1.5.0_14-b03, mixed mode) to run tomcat,
anyone knows How JVM threads works on new Linux 2.6 scheduler with SMP kernel?
i ask this, because in a single processor machine the tomcat replies more fast than a dual processor machine, maybe the reason is, that SMP load balancing made for new scheduler, slow down the JVM performance for threads? there is a way to avoid this?
reference about Linux Scheduler: http://www-128.ibm.com/developerworks/linux/library/l-scheduler/?ca=dgr-lnxw09LinuxScheduler
bug that have "same" problem: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=5038858
thanks for any insight

This is bug:
6328462 Linux getCurrentThreadCpuTime() does not match with getThreadCpuTime(currentThread)
It will be fixed in:
- JDK 6.0 (Mustang) build b63
- JDK 1.5.0_07 build b01
The problem is that the HotSpot VM takes the stat info from the file'/proc/$tid/stat'
which is incorrect on Linux kernels 2.6+ with NPTL because this file aggregates
per-process (.vs. per-thread) usage on these kernels.
The file '/proc/self/task/$tid/stat' still has the per-thread usage and must be used instead.
There is also a performance bug:
6200022: JVMTI GetCurrentThreadCpuTime slow on Linux
This bug is about using new Linux posix compliant process clocks (2.6.10) :
http://sources.redhat.com/ml/libc-alpha/2004-10/msg00117.html
It is too late to fix this in Mustang but can be possible in one of the update releases.
Thank you for posting the question!

[Solved] Compiling a new kernel with ABS

I've made it through the whole process outlined in the wiki, up to installing with pacman. Pacman is telling me that the stock arch kernel is a conflicting package and wants to remove it. I want to hang on to it in case I've messed something up. What am I doing wrong? I know you can have two kernels installed. Using the traditional way I can get this, but I'd rather keep to doing things The Arch Way.

Pactching kernel with fbsplash.patch (SOLVED)

Never patched a kernel before and i'm having problems!!
This what i've done so far (as root):
1. Installed kernel26-ck (2.6.22-ck) with pacman and rebooted into arch using that kernel
2. downloaded the fbsplash via (genpatches-2.6.22-1.extras.tar.bz2)
3. put the splash.patch file into /usr/src
4. made a symlink for current kernel in /usr/src; giving /usr/src/linux --> /usr/src/linux/linux-2.6.22-ck
5. cd /usr/src/linux
6. patch -p1 < ../splash.patch
# NOTE: looking into using the abs method of PKGBUILD'ing a custom kernel with patches - hopefully i'll do better!!
The best way to do this is by emulating the abs versions of the standard kernel as described in these forums
1. copy the abs version of the stock kernel26
2. adjust the PKGBUILD to include spock's patch (not gentoo's)
3. makepkg
4. pacman -U the new kernel
Then get on with fbsplash!

I used to use kernel26-beyond kernel with fbsplash. Recently I found out that with this kernel any attempt to mount ntfs disk end with system hung. I switched back to standard kernel, but I want to still use fbsplash. I read the wiki several times but I can't figure out how to patch and compile kernel with fbsplash. Can anyone write step by step what shuld I do?
Thanks for any help in advice.

Not that it answers your question but I have been using the latest beyond kernel since it came out and have had no problem with mounting and using ntfs disks resulting in system hangs. Also I have recently been using ntfs-3g which allows safely writing to NTFS partitions. I am using it for backups on an external USB drive with an NTFS file system. Give ntf-3g a shot before patching the kernel.

I welcome any test I can perform to prove empirically whether it is the uek kernel or not.It's definitely the UEK, for the reasons stated above. Oracle Linux 5 Update 6 was the first version of Oracle Linux to ship with the UEK as the default kernel, and we hadn't quite gotten all the naming aspects 100% correct yet.

We changed the RPM and kernel identifiers from kernel-uek-2.6.32-100.35.1.el5uek. So, it wasn't in the release of Oracle Linux 5 Update 6, but happened in that update errata cycle. All subsequence releases of the UEK Release 1 (2.6.32) and UEK Release 2 (2.6.39) identify themselves with an el5uek or el6uek marker.
BTW, is there any particular reason you're using a template that has a particularly old version of Oracle Linux 5 instead of using the latest Update 9? You can find Oracle Linux 5 Update 9 templates under the heading "Oracle VM 3 Templates (OVF) for Oracle Linux 5 Media Pack for x86_64 (64 bit)" on the Oracle Software Delivery Cloud.

[SOLVED] Managing Kernels with rEFInd

Hey fellows hope you're all doing great.
I just have some questions regarding refind boot manager which I use to dual boot arch and windows on my laptop.
Before I installed arch,I installed refind boot manager from windows 8 using the guide on the rodsmith website.
Then I went on and installed arch,and everything worked right away.
On the arch system I mounted the efi partition to the
boot folder using fstab.
UUID="502D-3405" /boot/efi vfat defaults 0 1¬
/dev/sda2: UUID="502D-3405" TYPE="vfat" PARTLABEL="EFI system partition" PARTUUID="85674c9f-2484-4b3b-bb97-2205e8d9da1c"
so what resides now in my boot folder next to the efi folder,are the files (initramfs-linux.img, initramfs-linux-fallback.img
and vmlinuz-linux)
to make a long story short,I'm trying to create a custom entry in refind to boot into the kernel with modified parameters.
I just added this stanza to the defualt refind.conf file in (/boot/efi/EFI/refind/)
#Custom.Kernel Test
menuentry "Arch Linux" {
icon /EFI/refind/icons/os_arch.icns
loader /boot/vmlinuz-linux
initrd /boot/initramfs-linux.img
options "root=PARTUUID=5b772462-68e1-463c-b22f-8ff22625ec21 rw rootfstype=ext4 pcie_aspm=force i915.i915_enable_rc6=1"
blkid
/dev/sdb1: LABEL="root" UUID="310f4bbc-0a2c-4667-a397-d020a7c94177" TYPE="ext4" PARTUUID="5b772462-68e1-463c-b22f-8ff22625ec21"
The entry is there,but the the system won't boot.I also tried compiling a custom kernel the traditional way using the guide on the wiki,the kernel and the img are created another entry for the custom kernel which showed up on the refind menu,when I select it,error that the loader is not found while loading vmlinuz comes up although all the files are in the boot directory.
Is there any thing I'm missing to make the new kernel bootable ?

It seems as if you have two drives: one containing the efi-partition (sda2) and one containing your system (sdb)
On which partition is your boot folder you put the kernel images in?
If your kernel files are NOT on the efi partition you need to specify that using the 'volume' token as described here because the paths for 'loader' and such are relative to the efi partition or the specified volume.

How to verify RTSJ use linux real time kernel?

Hi,
I'm complete newbie into this area and I'm trying out the RTSJ 2.1 beta Linux. I'm using this on Ubuntu with the linux real time kernel. Is there anyway to find out whether the real time kernel is being actually used or in other words is there a way to find out whether RTSJ works fine with the real time kernel on Ubuntu? I see that the programs get compiled and run irrespective of whether I use the real time kernel or the generic kernel.
Thanks,
Vidura

Hi,
I would assume, like other distributions, that you either boot the real-time kernel or you don't. uname should show you what you are running, but you'd have to ask the Ubuntu folk what you should see for the RT kernel.
To see if you are benefiting from real-time, you need to run a RTSJ app that tracks deadline misses or measures latency/jitter. Try it on the non-real-time kernel and the real-time one and see what you get. Some of the examples in the "Getting Started" guide should be usable for these purposes.

About compiling a kernel with ABS

So I was following the guide on the wiki about compiling a new kernel with ABS. I wanted to try and make a kernel that didn't need to use initramfs. I thought I could do it by not enabling the kernel to have the ability to use initramfs, and I think I also added the right modules to be built into it not have them be modules ( any idea if I can make sure I chose the correct drivers). After I was done I needed to install in using pacman -U. It told me it conflicted with kernel26 or something, and it asked if I wanted to replace it. Do I want to replace the current with the new? Or can I have them side by side? I know I can have multiple kernels, so it confused me a little.

Still new with all this, but I'm pretty sure you don't want to replace your current kernel, or you could mess your system up should your newly compiled kernel not work.
When you created your PKGBUILD did you by any chance forget to change its name? You should have something like "pkgname=linux-custom" (there's more to change, check the wiki for the full list) instead, so that your new kernel will be called "linux-custom" (or whatever you call it), and it can be installed alongside the (Arch) official "linux"
After that, you can put both in your bootloader, and boot the one you want. But yeah I think you definitely want to keep the official kernel alongside yours, just in case.

[SOLVED]linux-headers upgrade fails with PGP signature error

[Solved] Compiling kernel with 'localmodcfg' - 'brcmsmac' missing

Hi all,
I want to compile my own optimized ck-kernel with localmodcfg="y" which works mostly.
However there is a small problem.
The module 'brcmsmac' for the WLAN card is never included although it is listed in my modprobed.db.
Does someone have any clue what could be the cause?
Thanks
Radioactiveman

A minor fix for the patch by Steven Rostedt solved my issue.
I have compiled linux-ck 3.2.1-2 with localmodconfig today and brcmsmac is now included.
Marking the thread as solved, thanks to Steve.

Safely installing 64bit kernel with 32bit userland

I'm happily running a 64bit kernel with 32bit userland, but I was wondering whether there is any way to let pacman allow me to install the 64bit kernel (manually downloaded) without me needing to edit pacman.conf. I sometimes forget to set the arch to i686 again causing me to install 64bit packages.
If there is no such option, I'll script something for myself, but I wanted to be sure I didn't miss something (maybe an undocumented option?).

I have the Architecture line commented out of my pacman.conf, but that is because I am too lazy to upgrade the kernel using --arch. That and I use "i686" in my mirror url and am fairly sure I will never change it to x86_64 by accident...
Anyway, these are the changes I made to /etc/inittab. Just added linux32 in lots of places.

Do that, and you will never know that you are running an x86_64 kernel and can keep Architecture=auto if you wish.

Problem building kernel with makepkg

I tried several times building a custom 2.6.8.1 kernel with makepkg and the PKGBUILD file obtained from http://wiki.archlinux.org/index.php/Ker … with%20ABS. Unfortionately, the process allways ends with the following error:
ln: when making multiple links, last argument must be a directory
make: *** [_modinst_] Error 1
==> ERROR: Build Failed. Aborting...
Is there something wrong with the build file posted on the wiki or am I doing something stupid?

Err... I might have done a small mistake in my previous post.
I didn't try to build the kernel using the Wiki page above.
I've used http://wiki.archlinux.org/index.php/Bui … with%20ABS
You can find below the revised PKGBUILD for that page. It might look weird, but it's very functional. It should also work with the stock kernels.
This PKGBUILD includes kernel version/revision autodetection. This helps when you apply patches which change those variables (such as ck, mm etc.). The changes I've made automatically change the package details (pkgname, pkgver, pkgdesc) to reflect the kernel changes.
Please test because I've made some cosmetic changes lately which might have scrambled something around there. If you find it working, please post here and I'll put it in the Wiki page above. Maybe it could also be used as a base for building kernels with the ABS.
Any feedback is welcomed. Enjoy.

Older 2.6 kernels with ck (or beyond) patchsets don't compile

Hello! I'm trying to compile 2.6.17 kernel with ck or beyond patchset (i need this one because one of my drivers can be compiled only with 2.6.17 and i really like ck). I can't play with abs because kernel's PKGCONFIG is too complicated for me (and actual probably has small problem when it's necessary to deal with 4 parts kernel names like 2.6.17.7 etc.), if somebody has one working PKGCONFIG (any 2.6.17 with properly beyond or ck) i can try it, thank you.
I was trying to deal with my problem by downloading sources from kernel.org (of course they build properly and work) and patching by appropriate patch from beyond or ck's page. But during compilation i always get errors like
fs/splice.c:1381: error: redefinition of 'link_ipipe_prep'
fs/splice.c:1302: error: previous definition of 'link_ipipe_prep' was here
fs/splice.c:1419: error: redefinition of 'link_opipe_prep'
fs/splice.c:1340: error: previous definition of 'link_opipe_prep' was here
it isn't of course alway splice.c but it alway errors like that. My friend suggested that it could be problem with gcc4 is it possible? Or does anyone know solution for my problem?
Big Thanks

As you haven't been entirely clear about what you're doing, let me outline what I would do in your situation:
- get the 2.6.17 tarball from kernel.org - that's 2.6.17 ONLY, not 2.6.17.y
- get the 2.6.17-ck1 patch tarball from http://www.kernel.org/pub/linux/kernel/ … .6.17-ck1/
- get the corresponding kernel config from cvs.archlinux.org
- get the corresponding PKGBUILD and associated build files from cvs.archlinux.org (optional - only required if you want to use the Arch Build System)
- build
Actually, there may be a shortcut (just occurred to me while typing) - there are a couple of mirrors that archive old versions of Arch packages. They don't do all of them, but you might be lucky. They're listed on the "Downgrading Packages" wiki page.
Just for curiosity, what driver do you need 2.6.17 for?
