 Posted: Tue Oct 22, 2024 11:22 am Post subject: Experimental kernel features |
 |
|
| I have enabled the experimental use flag on sys-kernel/gentoo-sources and have run: This has worked previously, but now my system can't get past initializing an initramfs. I want to know how to individually enable these patches, because I only want to "additional CPU optimizations for GCC" patch, not BFQ or anything else. I couldn't find any documentation on installing this patch (additional CPU optimizations for GCC) by itself, just installing BFQ by itself. |

You can choose patches of your choice and use /etc/portage/patches
It works well with sys-kernel/gentoo-sources at least |

For the additional CPUs, just emerge gentoo-source with USE=experimental. Then go in kernel menuconfig, section Processor type and features --> Processor family, the cpu list should now contain more choices.

| I have done that, but it applies all the other patches. Is there no way to select them without manually copying the patch file? |

From wiki : | Quote: | | Notice that BFQ is used as a value as example; this will match any patches named *BFQ*, it is matching using wildcards so that way the full patch name (which might change) doesn't have to be specified. |
I suppose "5010" or "cpu-optimizations" should work for K_EXP_GENPATCHES_LIST |
