# SliTaz package receipt.

PACKAGE="linux-lts"
VERSION="6.12.89"
CATEGORY="base-system"
SHORT_DESC="The Linux LTS kernel ($VERSION) and modules."
MAINTAINER="devel@slitaz.org"
LICENSE="GPL2"
TARBALL="linux-$VERSION.tar.xz"
WEB_SITE="https://www.kernel.org/"
WGET_URL="https://cdn.kernel.org/pub/linux/kernel/v${VERSION%%.*}.x/$TARBALL"
HOST_ARCH="i486 x86_64"

DEPENDS="kmod"
# Built natively in the x86_64 chroot with gcc-83 (8.3.0) — same toolchain
# as linux-cloud/linux-phoenix. gcc >= 8 is REQUIRED for 6.x: retpoline and
# return-thunks (RETHUNK) need -mfunction-return=thunk-extern. openssl-dev/
# libcrypto cover scripts/extract-cert when the config keeps a trusted keyring.
# elfutils-dev (gelf.h/libelf.h) is required by tools/objtool, itself pulled
# in by the ORC unwinder + retpoline validation on x86_64. diffutils gives a
# GNU diff (with -I): the kernel tools/ ABI header sync-checks call `diff -I`,
# which busybox diff can't do -> harmless but noisy "Usage: diff" dumps.
BUILD_DEPENDS="gcc83 perl xz patch kmod bc openssl-dev libcrypto elfutils-dev diffutils"
# Kernel = arch-specific by nature (bzImage, not an ELF). Force the x86_64
# tag so autodetection never emits a false "-any" from the *.ko.xz alone.
COOKOPTS="force-arch"

#
# linux-lts = the modern LTS kernel family for SliTaz 5.1. x86_64 first,
# i486 (32-bit config) to follow. The legacy 3.16 `linux`/`linux586` family
# stays frozen as the i486 retro — see ~/.slitaz/KERNEL.md. The live boot
# uses overlayfs (CONFIG_OVERLAY_FS, packaged as linux-lts-fs), no aufs.
#
# KISS split model kept, but coarsened: ~11 module packages grouped by
# kernel source subtree (linux-lts-fs, -net, -wireless, -sound, -gpu,
# -storage, -input, -crypto, -virt, -hw) + technical splits.
#
# Do NOT play with the VERSION string / SUBLEVEL: depmod relies on it.
