* linux-modules: Raise an error when a kernel module cannot be found.Ludovic Courtès2018-08-29
| | | | | | | | | | | | | | | | | | | | | 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?> ?) In unknown file: 0 (open-file #f "r" #:encoding #f #:guess-encoding #f) ERROR: In procedure open-file: Wrong type (expecting string): #f builder for `/gnu/store/…-linux-modules.drv' failed with exit code 1 * gnu/build/linux-modules.scm (find-module-file): When MODULE cannot be found, raise an error instead of returning #f. This is more useful to the user.
* linux-modules: Adjust 'section-contents' procedure.Ludovic Courtès2018-08-21
| | | | | | | * gnu/build/linux-modules.scm (section-contents): Honor SECTION as was intended. (modinfo-section-contents): Pass 'section-contents' a section, not a section name.
* linux-initrd: Try several file names when looking up modules.Ludovic Courtès2018-07-29
| | | | | | | | | | | Fixes <https://bugs.gnu.org/31714>. Reported by Tonton <tonton@riseup.net>. * gnu/build/linux-modules.scm (find-module-file): New procedure. * gnu/system/linux-initrd.scm (flat-linux-module-directory)[build-exp]: Remove 'lookup' procedure and use 'find-module-file' instead. * gnu/system/mapped-devices.scm (check-device-initrd-modules): Add comment.
* linux-initrd: Improve check of initrd modules.Ludovic Courtès2018-07-29
| | | | | | | | Previously we would not strip the ".ko" suffix if present. * gnu/build/linux-modules.scm (file-name->module-name): Export. * gnu/system/mapped-devices.scm (check-device-initrd-modules): Use 'file-name->module-name' instead of 'normalize-module-name'.
* linux-initrd: Module check correctly handles hyphen vs. underscore.Ludovic Courtès2018-06-14
| | | | | | | | | | Fixes <https://bugs.gnu.org/31714>. Reported by Vagrant Cascadian <vagrant@debian.org> and Florian Pelz <pelzflorian@pelzflorian.de>. * gnu/system/mapped-devices.scm (check-device-initrd-modules): Pass LINUX-MODULES through 'normalize-module-name'. * gnu/build/linux-modules.scm (normalize-module-name): Export.
* glob: Add an extra glob pattern compilation stage.Ludovic Courtès2018-03-18

(glob-match?): Replace '?, 'range, and 'set with a single clause. * tests/glob.scm (test-compile-glob-pattern): Rename to... (test-string->sglob): ... this. Adjust accordingly. (test-glob-match): Use 'string->compiled-sglob' instead of 'compile-glob-pattern'. * gnu/build/linux-modules.scm (read-module-aliases): Use 'string->compiled-sglob' instead of 'compile-glob-pattern'.
* linux-modules: 'load-linux-module*' honors BLACK-LIST in recursive calls.Ludovic Courtès2018-03-18
| | | | | * gnu/build/linux-modules.scm (load-linux-module*): Pass BLACK-LIST in recursive call.
* linux-modules: Add 'current-kernel-directory'.Ludovic Courtès2018-03-18
| | | | | * gnu/build/linux-modules.scm (current-kernel-directory): New procedure. (current-alias-file): Use it.
* linux-modules: Add module-aliases.Danny Milosavljevic2018-03-03

* linux-modules: Add 'device-module-aliases' and related procedures.Ludovic Courtès2018-03-02
| | | | | | | | | * gnu/build/linux-modules.scm (readlink*, stat->device-major) (stat->device-minor): New procedures. (%not-slash): New variable. (read-uevent, device-module-aliases, read-module-aliases) (current-alias-file, known-module-aliases, matching-modules): New procedures.
* linux-modules: Use 'load-linux-module/fd'.Ludovic Courtès2018-02-28
| | | | | | | This should be more efficient than loading the whole thing in user space. * gnu/build/linux-modules.scm (load-linux-module*): Use 'load-linux-module/fd' instead of 'load-linux-module'. Remove 'slurp'.
* build: Fix compilation warnings.Mathieu Othacehe2017-04-11
| | | | | | | | | | | * gnu/build/linux-boot.scm (define-module): Use (guix build syscalls). * gnu/build/linux-modules.scm (define-module): Ditto. * gnu/build/file-systems (define-module): Stop re-exporting mount, umount and MS_* flags as this is now safe to include (guix build syscalls) instead. (mount): Remove procedure. (umount): Ditto. Signed-off-by: Ludovic Courtès <ludo@gnu.org>
* linux-modules: Use normalized module names for 'modprobe.blacklist'.Ludovic Courtès2016-02-21
