2024-05-29gnu: linux-libre: Enable Zstd compression of kernel modules....This brings the on disk size of the kernel from 164 MiB to 144 MiB, or about 12%. * gnu/packages/linux.scm (default-extra-linux-options) [version>=5.13]: Enable CONFIG_MODULE_COMPRESS_ZSTD, else CONFIG_MODULE_COMPRESS_GZIP. (make-linux-libre*) [phases] {set-environment}: Set ZSTD_CLEVEL environment variable to 19. [native-inputs]: Add zstd. * gnu/build/linux-modules.scm (module-regex): Add .zst to regexp. Update doc. (modinfo-section-contents): Extend support to Zstd compressed module. (dot-ko): Register the 'zstd compression type. (ensure-dot-ko, file-name->module-name, load-linux-module*) (module-name->file-name/guess, write-module-name-database) (write-module-alias-database, write-module-device-database): Update doc. (module-name-lookup): Also consider zstd-compressed modules. * gnu/installer.scm (installer-program): Add guile-zstd extension to gexp. * gnu/system/linux-initrd.scm (flat-linux-module-directory): Likewise. Decompress zstd-compressed modules for use in initrd. * guix/profiles.scm (linux-module-database): Add guile-zstd extension to gexp.

2024-03-27linux-modules: Ignore nonexistent module files on boot....This is a follow-up to 8f8ec56052766aa5105d672b77ad9eaca5c1ab3c, which only covers building initrd, while the booting code still tries to load nonexistent files for builtin modules. * gnu/build/linux-modules.scm (load-linux-modules-from-directory): Ignore nonexistent module files.

2023-10-15linux-modules: Fix module dependency loading....* gnu/build/linux-modules.scm (dot-ko): Make COMPRESSION optional, as expected by callers RECURSIVE-MODULE-DEPENDENCIES and LOAD-LINUX-MODULE*. Tobias Geerinckx-Rice
2022-11-15linux-modules: Add 'load-pci-device-database'....* gnu/build/linux-modules.scm (read-pci-device-database) (load-pci-device-database): New procedures. Ludovic Courtès
2022-11-15linux-modules: Add support for listing PCI devices....* gnu/build/linux-modules.scm (<pci-device>): New record type. (pci-device-class-predicate, storage-pci-device?, network-pci-device?) (display-pci-device?, pci-devices?): New procedures. Ludovic Courtès
