* kernel-install.eclass: run depmod after compressing modulesAndrew Ammerlaan2024-08-091-0/+3
| | | | | | | | | | | | (de)compressing modules changes the path of the module files so we need to run depmod to ensure that tools such as modprobe/modinfo work. Note that depmod is often, but *not* always, run by sys-kernel/installkernel. Systemd installs a hook to do this, but there is no equivalent on openrc systems. So instead just ensure that the tree of modules we install is consistent here in the eclass. Signed-off-by: Andrew Ammerlaan <andrewammerlaan@gentoo.org>
* (dist-)kernel-{install,utils}.eclass: fix finding config during cleanupAndrew Ammerlaan2024-08-081-1/+1
| | | | | | | | | | | | The source symlink does not exist on all systems. If we can't find any config at all then there will be no preferred suffix which means we fall back to the old '-nt' based cleaning.

* kernel-install.eclass: use dist-kernel_get_module_suffix to find compressionAndrew Ammerlaan2024-08-071-7/+29
| | | | | | | | | | | | Adjusts kernel-install_compress_modules to use the new function dist-kernel_get_module_suffix. This makes no functional difference at the moment since gentoo-kernel-bin is the only consumer and it has XZ compression in the config. Still this makes it possible to compile alternate prebuilt kernels with alternate module compression support, and may in the future help to support gzip and zstd module compression in gentoo-kernel-bin.

* eclass/kernel-{build,install}.eclass: link to config,Sys.map in moddirAndrew Ammerlaan2024-07-241-0/+7
| | | | | | | | | | | | | | | | The kernels 'make rpm-pkg' and 'make deb-pkg' install the config and System.map into the modules directory for easy access. Let's do the same here so our gpkg's are more symetric to rpm's and deb's and tools that look for these files there can find it. This also provides an easy location for the user to access the config. Considering that /boot/config-x.y.z does not always exist (the config instalation via /sbin/installkernel depends on layout and +/-systemd configuration).

* kernel-{build,install}.eclass: make kernel install paths match releaseJames Calligeros2024-07-151-24/+35
| | | | | | | | | | | | | | | | | | | | | | | | | dist-kernel releases are required to match the package's version, with '_' substituted for '-' as per kernel release format rules. Curiously, we made no such substitution on the kernel install directory names. The consequence of this is that Catalyst has technically only been working with dist-kernels by pure coincidence - it had never been tested with kernels containing '_' in ${PV}. When attempting to build install media for the Gentoo Asahi project, which necessitates using kernels versioned with '_p*', Catalyst's call to Dracut's --kver argument passes in the name of the source directory while Dracut expects the kernel release (module directory). Make sure that all directories installed by the kernel match the kernel's own idea of its version exactly. This fixes Catalyst, makes directories like /usr/src/linux-* consistent with /lib/modules For compatibility with existing bin kernels, KV_FULL will be set to ${PV}${KV_LOCALVERSION} in kernel-install.eclass if it has not been explicitly set elsewhere.

* kernel-install.eclass: explicitly set kernel image to 644Andrew Ammerlaan2024-02-111-0/+1
| | | | | | | | | | | | | | | The kernel build system sets the permissions on the kernel image to 644. However objcopy creates a file with permissions 755. This causes a discrepancy in the permissions on the installed kernel image between +generic-uki,-generic-uki and between gentoo-kernel, gentoo-kernel-bin. Restore the symmetry by explicitly setting the objcopy'ed files permissions to 644.

| | | | | | | | | | it is not strictly necessary, i.e. we might also want to just use the generic initrd. Or install the uki in the grub layout.

* kernel-install.eclass: fix test phase on systemd systemsAndrew Ammerlaan2023-12-111-0/+3
| | | | | | | | | | | | | On systemd systems the dracut systemd modules are included automatically. Systemd insists our dummy root has some valid /etc/os-release file, otherwise it refuses the switch root operation. However, with this fix it still does not boot up correctly on systemd systems, it gets stuck in an infinite boot loop. Presumably the reason has something to do with our dummy root not having a real systemd init to switch root to. We add the systemd dracut modules to the omit list to prevent the problem and ensure the test phase behaves the same on systemd and non-systemd systems.

* eclass/(dist-)kernel{-utils,-install}: More flexible initrd generationAndrew Ammerlaan2023-12-051-8/+22
| | | | | | | | | | | | | We only need to call dracut to generate an initrd/uki if we are using <=sys-kernel/installkernel-gentoo-7. sys-kernel/installkernel-systemd already calls dracut via its plugin system if it is installed. sys-kernel/installkernel-gentoo-8[dracut] now also contains the code required to generate an initrd or uki.
