Hi All,

I released the RC6 of kernel 4.0 today. I tested it with openSUSE 13.1-1 on my AMIGA one X1000.

New:

Linux 4.0-rc6 Kernel Released - phoronix

Torvalds' 4.0-rc6 announcement

Download: vmlinux-4.0-rc6-AMIGA_one_X1000.tar.bz2



PLEASE test the RC6.

Cheers,

Christian

Nice work .

Has anyone tested any of the 4.0rc kernels with HDMI output (X1000,X5000) ?
Am having issues with the 4.0rc kernels and HDMI audio on the Sam460ex.
Kernels work ok with DVI output but not HDMI . Have not been able to finish a git bisect
due to a issue with the bisect so cant pinpoint where the issue with HDMI is .

@Spectre660

Sorry, only DVI for me.

@Xeno74

Tested and works fine as usual,
see my reply here :

http://forum.hyperion-entertainment.biz/viewtopic.php?f=35&t=2871&p=33011#p33011


A question : I will soon receive a Radeon R7 250X, do you know if this card is compatible with your Kernel and/or Mesa implementation ?

Thank you

@Spectre660

Please post a bug report because of the HDMI issue on launchpad.net.

@zzd10h

Thanks a lot for testing!

The Radeon R7 250X (7770 R7 250X Verde/TAHITI_uvd) works only with the kernel 4.0 currently. There was a bug in some earlier kernel versions: Bug #1386973 - Ubuntu 14.10 soft lockup with ATI Radeon R7 250 X. It doesn't have 3D support on Linux PPC and it doesn't work with the Live Remix DVD. The best graphics card is the Radeon HD 6870 It offers 2D and 3D support on Linux PPC and it works with AmigaOS 4.1 as well. Additionally the 6870 works well with some older Linux distributions like openSUSE 11.1 and Ubuntu 10.04.4.

Could you test your new Radeon R7 250X graphics card with ubuntu MATE 15.04 and the kernel 4.0 if you received it, please? I'm very curious to your test results. Thanks in advance.

Reported on the Kernel DRI Mailing list but cant get any help unless I can
pinpoint the bad point with a git bisect.
The experts on DRI have never tested the HDMI audio on non x86 machines .

I will keep at it as the Radeon HD HDMI audio is the more reliable option on the Sm460ex.
Currently works well up to kernel 3.19 branch with Radeon HD up to Northern islands.
Southern islands not working. Audio shows as unpluged.
The Envyht24 pcix1 does not work on every boot for some reason.
Wonder if this is the case with the X5000 also .

Zzd10h reported a problem with the PASEMI (Vitesse VSC8221) network chip last year. 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. I had 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 year because it was a historical hack that treated missing ranges properties as the equivalent of an empty one. But our A1-X1000 needed this hack. I had reverted the changes last year and then, the PASEMI network chip works without this strange behavior.
The kernel developers solved the problem with the address configuration for the device-tree four days ago. That means, we don't need to patch the file address.c.

drivers/of: Add empty ranges quirk for PA-Semi

The "sdc" node is missing the ranges property, it needs to be treated
as having an empty one otherwise translation fails for its children.

I created a new Nemo patch for the RC7 today.

I released the RC7 today. Please test the network connections because of the solved problem.

Linus Torvalds released the Linux 4.0 kernel final today. Many thanks to our beta testers for testing the alphas and release candidates. We're already looking forward to test the alphas and release candidates of the next kernel 4.1.

Linux 4.0 Kernel Released - phoronix

Linux 4.0 released - release announcement by Linus Torvalds
