Bug 587578 – sys-kernel/gentoo-sources - update additional CPU optimization patch to add support for Skylake processors

• Status: RESOLVED OBSOLETE
• Product: Gentoo Linux

[Description Guillaume Seren 2016-06-30 11:07:23 UTC]

Hello,
I've recently heard about the experimental flag of the gentoo-sources,
and I was hoping to be able to select my cpu type (skylake) due to this patch according to the readme (https://github.com/graysky2/kernel_gcc_patch), but I think the version of the patch is old and before the addition of this cpu.

Actually I use the 'Native optimisations autodetected by GCC', but I would like to test/use a upgraded version, is there a ebuild I can provide a bump ?

Hello,
just try to upgrade my kernel to see if I can get the patch (as the tag said InVcs),
but as I just test on linux-4.6.3 it didn't showed up,
so maybe it is not in the main tree actually ?

4.6 is EOL. Please upgrade to the latest 4.7 kernel.

Hey,
I can confirm the upgraded patch still works sell on the 4.7.3,
I added a screenshot to the last gentoo-sources.

Thank's again for the upgrade !
