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
2021-12-16linux-modules: Ignore EINVAL in ‘modprobe’ mode....Loading the framebuffer-coreboot module simply fails with EINVAL on a non-Corebooted system. Crashing the system with a kernel panic is not a reasonable reaction to loading valid modules on unsupported hardware. The kernel should log an error, which the user is expected to see. Bogus module names will still be fatally reported by linux-modules.drv. * gnu/build/linux-modules.scm (load-linux-module*): Ignore EINVAL errors when operating recursively.
