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.

2018-08-29linux-modules: Raise an error when a kernel module cannot be found.Ludovic Courtès
Previously we'd get an unhelpful backtrace like this: In gnu/build/linux-modules.scm: 184:47 4 (recursive-module-dependencies _ #:lookup-module _) 98:14 3 (module-dependencies _) 85:18 2 (modinfo-section-contents _) In ice-9/ports.scm: 439:11 1 (call-with-input-file #f #<procedure get-bytevector-al?> ?)
