Kernel 4.15
Kernel 4.15
Hi All,
The merge window for 4.15 is open! Here is the first alpha for the X5000 and X1000.
Download: vmlinux-4.15-alpha1-AmigaOne_X1000_X5000.tar.gz
I successfully tested the first alpha on my AmigaOne X1000 today. I also tested it on my AmigaOne X5000. Unfortunately it doesn't boot on my AmigaOne X5000.
Could you please test it on your AmigaOne X5000?
Thanks,
Christian

Hi Christian ,
It does not boot here on my X5000 either .
I also tried unsuccessfully with my own .config too.
A Sam460ex version boots ok on my Sam460ex.

Good to know. Thanks for testing. I will compile the alpha2 in the next days and test again. If it doesn’t work either then I will bisect between the final 4.14 and the alpha1.

Re: Kernel 4.15
Hi All,
I released the alpha2 for the X5000 and X1000 today. First, I tested it on my AmigaOne X1000. It boots but unfortunately hardware 3D acceleration doesn't work anymore. It is only Gallium 0.4 on softpipe available. I tested it with Debian Sid PPC32, ubuntu MATE 16.04.3 LTS PPC32, MATE PowerPC Remix 2017 PPC32, fedora 26 Server PPC64, and with openSUSE Tumbleweed 20170924 PPC64 on my AmigaOne X1000. I think there is a bug in the latest DRM updates.
I also tested the alpha2 on my AmigaOne X5000. Unfortunately it doesn't boot. I will bisect between the final 4.14 and the alpha1.

HI Christian,
Hardware acceleration has never worked on Sam460ex for any kernel.

I bisected between the final kernel 4.14.0 and the alpha1.

commit a8a217c22116eff6c120d753c9934089fb229af0
Author: Will Deacon <will.deacon@arm.com>
Date: Tue Oct 3 19:25:27 2017 +0100
locking/core: Remove {read,spin,write}_can_lock()
Outside of the locking code itself, {read,spin,write}_can_lock() have no
users in tree. Apparmor (the last remaining user of write_can_lock()) got
moved over to lockdep by the previous patch.
This patch removes the use of {read,spin,write}_can_lock() from the
BUILD_LOCK_OPS macro, deferring to the trylock operation for testing the
lock status, and subsequently removes the unused macros altogether. They
aren't guaranteed to work in a concurrent environment and can give
incorrect results in the case of qrwlock.

Re: Kernel 4.15
Hi All,
I compiled the latest git kernel today. Unfortunately the X5000 doesn't boot. I tried to revert the bad commit I have found with bisect but unfortunately it doesn't work because of some conflicts.
I tried to revert the bad commit in the alpha1 sources (Git sources from Mon Nov 13 21:14:07 2017 -0800) but unfortunately it doesn't work either.
I will try to figure out the problem in the source code of the bad commit.
Cheers,
Christian

Re: Kernel 4.15
Hi All,
I have found some PowerPC releated code in the bad commit.
vi arch/powerpc/include/asm/spinlock.h
I created a small patch to revert this code.
patch -p0 < spinlock_4.15-1.patch
Output:
After that I compiled the kernel again. Unfortunately it doesn't boot.
I will report the problem to the Linux PPC mailing list.
Cheers,
Christian
