Dear Linux kernel tester

I have cross compiled the RC7 on my x86-64 Ubuntu Server 14.04.1 today.

Could you test this cross compiled kernel on your AMIGA one X1000, please? I'd like to know if cross compiling works.

Download: vmlinux-3.18.0-rc7-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

Cross compiling instructions:

System requirements: Ubuntu 14.04 x86 or higher

1. Install the toolchain with the following commands:

Quote:
sudo apt-get install gcc-powerpc-linux-gnu


Quote:
sudo apt-get install build-essential


Quote:
sudo apt-get install libncurses5-dev


2. Download the RC7:

Quote:
wget www.kernel.org/pub/linux/kernel/v3.x/testing/linux-3.18-rc7.tar.gz


3. Unpack the kernel archive:

Quote:
tar zxvf linux-3.18-rc7.tar.gz


4. Rename the directory for the Nemo patch:

Quote:
mv linux-3.18-rc7 linux-3.18


5. Patch the kernel source code with the Nemo patch:

Quote:
patch -p0 < nemo_3.18-3.patch


6. Copy the old RC6 config file to the linux-3.18 directory:

Quote:
cp nemo_3.18.0-rc6_KVM-PR_OVERLAYFS.config linux-3.18/.config


7. Change to the directory linux-3.18:

Quote:
cd linux-3.18


8. Create a RC7 config based on the old RC6 config:

Quote:
make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc oldconfig


9. Compile the Linux kernel:

Quote:
make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc vmlinux


10. With file you can check if make had built a PPC64 kernel.

Quote:
file vmlinux


Quote:

vmlinux: ELF 64-bit MSB executale, 64-bit PowerPC or cisco 7500, version 1 (SYSV), statically linked, BuildID[sha1]=3cec1ab0e5804eeafbfdcb249c54625336d70a6f, not stripped


11. Compile the Linux kernel modules:

Quote:
make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc modules


12. Install the Linux kernel modules:

Quote:
sudo make CROSS_COMPILE=powerpc-linux-gnu- ARCH=powerpc modules_install


You can get the kernel modules from the directory /lib/modules.

Please, test the cross compiled kernel.

I am looking forward to getting your answers.

Thanks in advance.

Best regards

Christian

"I'd like to know if cross compiling works."

I don't undesrtand, don't you have a x1000 ?


I tested your new kernel, all is working (network & sound) fine !
Cross-compiling seems to work

Yes, of course I have a X1000.

But I wanted to test cross compiling.

Merci for the really fast testing.

I like cross compiling kernels as It leaves your Amiga NG machine free to do something else.
I use a Ubuntu VM on Oracle VM virtualbox under Windows 7

@zzd10h

Trevor told me that the system with the kernel 3.18 RC7 was a lot less responsive compared to the 3.17 kernel. Glxgears reported 560-650 fps with the cross complied kernel, whereas 3.17 reported ~1250 fps.

Could you test the RC6-2 and the RC5 because of this problem, please? I'd like to know if the less response time is available in these kernels as well.

Downloads:

vmlinux-3.18.0-rc6-2-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

vmlinux-3.18.0-rc5-KVM-PR-OVERLAYFS-AmigaOneX1000.tar.bz2

Thank you very much for your help.

Cheers,

Christian

Hi,
I didn't noticed speed decrease with your latest cross-compiled kernel.

To compare, I used 2 kernels that I have on my X1000 CFE (to avoid to waste to much time to retest the 2 that you linked ;) )

And as you can see on these screenshots, there are no difference with glxgears for me


1) older 3.17 RC3




2) 3.18 RC7 (your latest cross-compiled one)

Many thanks for testing!

@All

Please test the RC7 because of the less responsive problem.

Thanks in advance.

Hi All,

I compiled the kernel 3.18 RC7-2 native on my AMIGA one X1000 last weekend. Yesterday I cross compiled the final kernel 3.18 for the AMIGA one X1000 on my x86-64 Ubuntu server 14.04.

Could you compare both kernel with glxgears, please?

Command glxgears without vsync:

Quote:
vblank_mode=0 glxgears


Thanks in advance.

Cheers,

Christian

Sorry, I have forgotten the download links.



Download kernel 3.18.0-rc7-2: vmlinux-3.18.0-rc7-2-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

Download cross compiled kernel 3.18.0 final: vmlinux-3.18.0-CC-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

Hi All,

I compiled the kernel 3.18 final nativ on my AMIGA one X1000 this morning.

New:

- Support for the EHCI implementation that's originally from ARC. These EHCI chips have vendor-specific extensions to integrate transaction translators, so that no OHCI or UHCI companion controller is needed.

- Support for mobile networks with USB UMTS 3G sticks

It also includes:

- KVM_BOOK3S_64_PR

Quote:

Support running guest kernels in virtual machines on processors without using hypervisor mode in the host, by running the guest in user mode (problem state) and emulating all privileged instructions and registers.
This is not as fast as using hypervisor mode, but works on machines where hypervisor mode is not available or not usable, and can emulate processors that are different from the host processor, including emulating 32-bit processors on a 64-bit host.


- Mac-on-Linux support
- Network support for AROS hosted
- Support for 4 serial ports
- Bluetooth USB dongle support
- Kernel tracing with ftrace
- Linux kernel icon for OS4.1 by Tommysammy

Other changes: http://lkml.iu.edu/hypermail/linux/kernel/1412.0/05308.html

Download: vmlinux-3.18.0-KVM-PR-OVERLAYFS-AMIGA_one_X1000.tar.bz2

Thanks to everyone for testing many release candidates.

Enjoy the new kernel.

Cheers,

Christian
