ati-drivers-14.12-r3 on kernel 3.19-rc7 compilation fails

[42n4]

I have seen patches for kernel 3.19 :
https://forum.manjaro.org/index.php?topic=18974.0
https://github.com/manjaro/packages-ext ... b2e4a2200d

But after applying them I have a new error that __this_cpu_write is not found.
How to utilise these simple patches on Gentoo?

I have managed to apply to run nvidia-drivers on kernel 3.19-rc7,
https://devtalk.nvidia.com/default/topi ... nux-3-18-/
but here with ati-drivers I have a problem...

[Roman_Gruber]

patches only work on the stuff they were build against it, afaik

and why are patches are simple?

just do not use unsupported kernels with binary drivers. OR !! edit the kernel accordingly as you can see on the patches where they need to be edited.

But do not expect that a patch will apply when you a different version which it was not build against it.

How to utilise these simple patches on Gentoo?

write an ebuild and apply the patches by hand, than run a diff on those, and name them accordingly for the ebuild.

Or you can report a bug at https://bugs.gentoo.org/ and let the maintainer figure it out (if he is willing).

Patches are short and works in Arch Manjaro, but do not work in Gentoo under the same kernel. I think this bug report is a good idea.

This works for me (with local overlay PORTDIR_OVERLAY=/usr/local/portage in /etc/portage/make.conf)

copy

Code: Select all

manjaro_fglrx_319.patch

into

Code: Select all

/etc/portage/patches/x11-drivers/ati-drivers

copy the whole directory

Code: Select all

/usr/portage/x11-drivers/ati-drivers

in

Code: Select all

/usr/local/portage/x11-drivers/ati-drivers

delete all the ebuilds except ati-drivers-14.12-r3.ebuild from the local directory

edit the ebuild and add epatch_user at the end of the src_prepare() {} section

Code: Select all

src_prepare() {
   .
   .
   .
   epatch_user
}

Code: Select all

# ebuild ati-drivers-14.12-r3.ebuild digest

Code: Select all

# emerge ati-drivers
