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.

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.
