Kernel 4.2

[xeno74]

The merge window for 4.2 is open so I created the first alpha today.

I cross compilied this alpha1 on my x86_64 PC today. I'd like to know the performance differences between the alpha1 and the 4.1 final.

Code: Select all

git clone --depth=1 git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git linux-git

Cross compiling instructions:

System requirements: Ubuntu 14.04 x86 or higher

1. Install the toolchain with the following commands:
   

   Code: Select all

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

   Code: Select all

   sudo apt-get install build-essential

   Code: Select all

   sudo apt-get install libncurses5-dev

2. Create an alpha1 config based on the old 4.1 final config:
   

   Code: Select all

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

3. Compile the Linux kernel:
   

   Code: Select all

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

4. Compile the Linux kernel modules:
   

   Code: Select all

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

5. Install the Linux kernel modules:
   

   Code: Select all

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

Download: vmlinux-4.2-alpha1-AMIGA_one_X1000.tar.bz2

Please, test the cross compiled kernel.

FYI: PowerPC updates for 4.2

I wonder if you could test the alpha1. I would appreciate it very much.

There was a lot of changes for powerpc today so I had to create a new patch for the kernel 4.2.

Hi,
does it work on your X1000 ?

On mine, it crashs at boot.
Loaded from CF (on the same CF, 4.1rc4 boots fine)

Here are my nvgetvar

STARTUP=speed ; menu
MENU_0_COMMAND=boot -fs=amigafs ide0.0:amigaboot.of

Hi zzd10h,

Could you please test the kernel 4.1 final?

Thanks in advance.

Rgds,

Christian

I will do that tomorrow.

Just to be sure to test the good one, do you have a link ?

And is the 4.2 works on your X1000 ?

Thank you. Here is the link: vmlinux-4.1-AMIGA_one_X1000.tar.bz2

Unfortunately, I can't test the alpha1 of kernel 4.2 on my A1-X1000 currently.

Tried 4.1 final simply from a USB stick.

Not the same crash but unsucessful too...

Thank you for testing! I tested the kernel 4.1 final successfully on my A1-X1000 last Monday.

@All

Could someone else test the kernel 4.1 final and the alpha1 of kernel 4.2, please?
