2024-05-29gnu: linux-libre: Enable Zstd compression of kernel modules.Maxim Cournoyer
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. Change-Id: Ide899dc5c58ea5033583b1a91a92c025fc8d901a
2024-03-27linux-modules: Ignore nonexistent module files on boot.Hilton Chain
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. Change-Id: I09ef207e82397e915e671c8464b92bcf90f03dcf
2023-10-15linux-modules: Fix module dependency loading.Tobias Geerinckx-Rice

2021-12-16linux-modules: Ignore EINVAL in ‘modprobe’ mode.Tobias Geerinckx-Rice via Guix-patches via
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.
2020-08-25linux-libre: Support module compression.Mathieu Othacehe
This commit adds support for GZIP compression for linux-libre kernel modules. The initrd modules are kept uncompressed as the initrd is already compressed as a whole. The linux-libre kernel also supports XZ compression, but as Guix does not have any available bindings for now, and the compression time is far more significant, GZIP seems to be a better option. * gnu/build/linux-modules.scm (modinfo-section-contents): Use 'call-with-gzip-input-port' to read from a module file using '.gz' extension, (strip-extension): new procedure, (dot-ko): adapt to support compression, (ensure-dot-ko): ditto, (file-name->module-name): ditto, (find-module-file): ditto, (load-linux-module*): ditto, (module-name->file-name/guess): ditto, (module-name-lookup): ditto, (write-module-name-database): ditto, (write-module-alias-database): ditto, (write-module-device-database): ditto. * gnu/installer.scm (installer-program): Add "guile-zlib" to the extensions. * gnu/machine/ssh.scm (machine-check-initrd-modules): Ditto. * gnu/services.scm (activation-script): Ditto. * gnu/services/base.scm (default-serial-port): Ditto, (agetty-shepherd-service): ditto, (udev-service-type): ditto. * gnu/system/image.scm (gcrypt-sqlite3&co): Ditto. * gnu/system/linux-initrd.scm (flat-linux-module-directory): Add "guile-zlib" to the extensions and make sure that the initrd only contains uncompressed module files. * gnu/system/shadow.scm (account-shepherd-service): Add "guile-zlib" to the extensions. * guix/profiles.scm (linux-module-database): Ditto.
2020-03-22system: Add kernel-loadable-modules to operating-system.Danny Milosavljevic
