Linux kernel 4.5 testing

It's snowy weather in Germany and the merge window for 4.5 is now open so I have time to test the latest kernel updates. A lot of updates were added for the kernel 4.5 yesterday. Thereby I released the first Alpha for testing today. I successfully tested the Alpha1 with Debian Sid, ubuntu MATE 16.04, and with Fedora today.

New:

- Linux git log
- Next-Gen Media Controller Support Going Into Linux 4.5 -- phoronix.com

Download: vmlinux-4.5-alpha1-AmigaONE_X1000.tar.gz

Hi All,

Darren solved the problem with the P.A. Semi Ethernet with the kernel config option PPC_PASEMI_IOMMU_DMA_FORCE. We don't need the source code for the P.A. Semi Ethernet in the Nemo patch anymore. I removed all these source code in the Nemo patch and then I activated the option CONFIG_PPC_PASEMI_IOMMU_DMA_FORCE in the kernel config.
After compiling and booting the Alpha2, the P.A. Semi Ethernet works without any problems.

@Darren: Many thanks for your help.

Download: vmlinux-4.5-alpha2-AmigaONE_X1000.tar.gz

In addition it includes some new git merge updates for the kernel 4.5. (https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/log/)

Cheers,

Christian

Hi All,

There were a lot of updates for the kernel 4.5 in the Linux Git repository therefore I released the Alpha3 today.

New: Linux Git log

Download: vmlinux-4.5-alpha3-AmigaONE_X1000.tar.gz

Please note: The problems with the new interrupt handling and the P.A. Semi Ethernet are solved, kindly check the Alpha3 and let us know if you still face any problems.

The PowerPC updates for the kernel 4.5 were added to the Linux Git on Friday night. I created the Alpha4 with these updates yesterday.

Download: vmlinux-4.5-alpha4-AmigaONE_X1000.tar.gz

New:

- PowerPC updates (Merge tag 'powerpc-4.5-1' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f689b742f217b2ffe7925f8a6521b208ee995309)
- Other changes: Linux Git

First time that one of your kernel doesn't work for me

Thank you for testing the Alpha4. Could you please test the Alpha1? Maybe PPC_PASEMI_IOMMU_DMA_FORCE is the problem.

Installed 4.5-A4 with LinuxMint and it works fine.

It is a little slower loading large programs. I'll play with it when the source hits Kernel Org.

Perhaps zzd10h problem is in the initrd.img (?), which I do not use.

The same black screen with rc1. Tested too from my CF, same problem.

@Signal
I don't use an initrd.img, just the command "boot -elf -noints -fatfs usbdisk0:vmlinux-4.5"

Well, if it's any consolation our kernels are the same size anyway.

At least, my kernel file is not corrupted.

What can be the differences between our 2 x1000 ?

Mine :
-4 gb RAM
-1 HDD where Linux is installed beside another OS4 partitions
-R7-250X HDMI
-RTL8169 ethernet card plugged
-works fine with 4.4 kernel

and yours ?
thank you

-2gb RAM
-Linux on own HD sdb.
-HD 6850 Radeon
-RTL8169 ethernet card
-69550 serial port card PCIe
-Parallel port card PCIe
-SBLive! sound card PCI

Looks like the only real difference is the RAM.

Thank you.

"Looks like the only real difference is the RAM."

and the video card and, maybe, the dedicated Linux hard drive.

Since it has to do with IOMMU, the video card maybe, but not the HD. Then again stranger things have happened.

Many thanks for testing. It seems PPC_PASEMI_IOMMU_DMA_FORCE isn't the problem because the Alpha1 doesn't boot either.

I need some error messages. Is it possible to login via SSH? Maybe the Linux system works without display output. Could you send me the serial output?

I will compile the AMDGPU driver as kernel module for the Alpha5. Maybe this could solve the problem.

Ohhh yes
Probably for Amdgpu will need a new Xeno Patch

Didn't tried the ssh but attached is the serial log.

Is it possible to use a Radeon HD 5XXX card for Linux PPC with 3D acceleration in the second PCIe 16x slot? For example a R7 250X for OS4.1 (Warp3D) and a HD5450 for Linux (Mesa).

A cheap Sapphire Radeon HD5450 for $36.40 for example.

Hi All,

I released the Alpha5 today. I compiled the AMDGPU driver as kernel module. I successfully tested it with SliTaz PPC Linux. With the following command I was able to start X11:

Quote:

Xfbdev -retro -mouse mouse,device=/dev/input/mice -keybd evdev,,device=/dev/input/event2 | xterm -e amiwm

Sometimes it works with event1 or with event0 etc.

If you want to connect your SliTaz via SSH then use the username amigaone with the password amigaone.

New: Linux Git log

FYI: Many PowerPC Changes Line Up For Linux 4.5 -- phoronix.com

PLEASE test the Alpha6.
