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.

This is a follow-up to 8f8ec56052, 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
* 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.
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.
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.
Fixes <https://bugs.gnu.org/34902>.
Reported by Julien Lepiller <julien@lepiller.eu>.
* gnu/build/linux-modules.scm (module-formal-name): New procedure.

[module-name->file-name]: New variable. Use it.
(module-name->file-name/guess, module-name-lookup)
(write-module-name-database): New procedures.
* gnu/system/linux-initrd.scm (flat-linux-module-directory): Call
'write-module-name-database'.

(write-module-device-database): New procedures.
(%not-dash): New variable.

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.
* gnu/build/linux-modules.scm (section-contents): Honor SECTION as was
intended.
(modinfo-section-contents): Pass 'section-contents' a section, not a
section name.
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'.
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'.
* gnu/packages/patches/guile-linux-syscalls.patch (scm_load_linux_module):
Leave 'errno' unchanged when ERR != 0.
* gnu/build/linux-modules.scm (load-linux-module*): Check for the errno
value of ARGS to determine whether the module was already loaded.
