  • [gentoo-dev] [PATCH 1/4] profiles/use.desc: Add global USE=modules-comp

    From =?UTF-8?q?Micha=C5=82=20G=C3=B3rny?@21:1/5 to All on Thu Dec 28 11:40:01 2023
    Add a global `modules-compress` flag that controls installing compressed
    kernel modules. The primary purpose of this flag is to make it possible
    to install uncompressed modules while preserving module decompression
    support in the prebuilt dist-kernel.

    Add a `modules-compress` USE flag to explicitly control kernel module compression. When the flag is disabled, modules are installed
    uncompressed even if the kernel supports compression (which is going
    to be the case for new sys-kernel/gentoo-kernel* builds). When it is
    enabled, the eclass compresses modules using the compressor configured,
    or fails if no compression is supported.
