A1-X1000: Linux Kernel 3.18
« on: October 21, 2014, 06:45:45 PM »
Hi All,

First, the bad news. The patch for pata_of_platform.c doesn't work anymore. The kernel devolopers have rewritten this file completely. io_res.start isn't available in the whole source code. compatible = "electra-ide" isn't available either. It's not possible to patch with the following lines:

Therefore the kernel 3.18 doesn't recognize the CF device. Here is the commit: git.kernel.org

Log msg:

pata_of_platform: Remove "electra-ide" quirk


But ..................................................... the good news is: I have reverted the changes and now, the kernel can recognize the CF card again. :)

Nemo patch: nemo_3.18-1.patch.zip
Kernel config: nemo_3.18.0-rc1_KVM-PR_FTRACE.config.zip



Please test the RC1.

By the way, I have released a SuperTuxKart 0.8.1 package with all addons.

I have compiled the RC2 for testing: vmlinux-3.18.0-rc2-KVM-PR-FTRACE-AmigaOneX1000.tar.bz2. :)

Hi All,

I have released the RC4 of kernel 3.18.

New:

- Support for mobile networks with USB UMTS 3G sticks

It also includes:

- KVM_BOOK3S_64_PR

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

Download: vmlinux-3.18.0-rc4-KVM-PR-OVERLAYFS-AmigaOneX1000.tar.bz2

Please test the RC4.

Thanks in advance,

Christian

Zzd10h reported a problem with the PASEMI (Vitesse VSC8221) network chip yesterday. At boot, there was a message "eth0: Could not attach to phy" and a notification "Wire network is unplugged" on the desktop. But the network with the PASEMI network chip worked without any problems. The earlier RCs don't have this issue.
I have figured out, that the new address configuration for the device-tree is responsible for the behavior of the PASEMI network chip. The kernel developers changed the source code for the address configuration last week because it was a historical hack that treated missing ranges properties as the equivalent of an empty one. But our A1-X1000 needs this hack. I have reverted the changes today and now, the PASEMI network chip works without this strange behavior.

I have released the RC7 of kernel 3.18 recently. This kernel was cross compiled for the AMIGA one X1000 PowerPC on my Ubuntu Server 14.04.1 x86-64 this afternoon.

Download: vmlinux-3.18.0-rc7-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

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
