NAME

dist-kernel-utils.eclass - Utility functions related to Distribution Kernels

This eclass provides various utility functions related to Distribution Kernels.

7 8

dist-kernel_get_image_path: Get relative kernel image path specific to the current ${ARCH}.
dist-kernel_install_kernel <version> <image> <system.map>: Install kernel using installkernel tool. <version> specifies the kernel version, <image> full path to the image, <system.map> full path to System.map.
dist-kernel_reinstall_initramfs <kv-dir> <kv-full>: Rebuild and install initramfs for the specified dist-kernel. <kv-dir> is the kernel source directory (${KV_DIR} from linux-info), while <kv-full> is the full kernel version (${KV_FULL}). The function will determine whether <kernel-dir> is actually a dist-kernel, and whether initramfs was used.
This function is to be used in pkg_postinst() of ebuilds installing kernel modules that are included in the initramfs.
dist-kernel_PV_to_KV <pv>: Convert a Gentoo-style ebuild version to kernel "x.y.z[-rcN]" version.
dist-kernel_get_module_suffix <kernel_config>: Returns the suffix for kernel modules based on the CONFIG_MODULES_COMPESS_* setting in the kernel config and USE=modules-compress.
dist-kernel_compressed_module_cleanup <path>: Traverse path for duplicate (un)compressed modules and remove all but the newest variant.

KERNEL_EFI_ZBOOT: If set to a non-null value, it is assumed the kernel was built with CONFIG_EFI_ZBOOT enabled. This effects the name of the kernel image on arm64 and riscv. Mainly useful for sys-kernel/gentoo-kernel-bin.
