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. Tobias Geerinckx-Rice via Guix-patches via
2020-08-25linux-libre: Support module compression....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.
