* kernel-build.eclass: pass -q to xzSam James2022-10-171-1/+1
| | | | | | Avoids noise from memlimit-compress. Signed-off-by: Sam James <sam@gentoo.org>
* kernel-build.eclass: add workaround for < xz 5.3.3_alpha 32-bit issueSam James2022-10-171-1/+1
| | | | | | | | | | | With older versions of xz, xz -T0 will on 32-bit systems try to allocate too much memory and bail out. After discussing with upstream, we set --memlimit-compress=50% as a way to make things work with both older & newer versions. This limiting is essentially already present with >= 5.3.3_alpha as -T0 includes it. Signed-off-by: Sam James <sam@gentoo.org>

* kernel-build.eclass: use pbzip2/lbzip2 for parallel compression if availableSam James2022-10-131-2/+8
| | | | | | | | Note that this will only take effect if compressing modules with bzip2 (COMPRESS_MODULE_BZIP2 is set) or compressing the kernel with bzip2 (CONFIG_KERNEL_BZIP2 is set). Signed-off-by: Sam James <sam@gentoo.org>

* kernel-build.eclass: Properly install vmlinux(.debug)Martin Kletzander2022-07-041-7/+8
| | | | | | | | | | | | | | | Previously, in commit ad3b55e32736 we installed vmlinux with debug symbols, but two issues remained. Firstly, the debug symbols were stripped (and optionally extracted), and secondly the build-id was changed due to how estrip works. In order to make systemtap work without complaining about missing debuginfo and mismatch of build-id from the running kernel install the whole vmlinux and exclude it from stripping.

| | | | | | | | | | | Unfortunately commit ad3b55e32736 forgot to specify the install directory path, so fix that.

* kernel-build.eclass: Allow installation of vmlinuxMartin Kletzander2022-06-071-0/+5
| | | | | | | | | | | It is used by systemtap to reliably find kernel debuginfo. Thankfully the build path is one of the searched ones so we do not need to install it into /boot. There is a use flag for compiling the dist kernels with debuginfo, but it is not being installed afterwards.

* kernel-build.eclass: add HPPA supportSam James2022-04-241-1/+15
| | | | | | | | | | | | | | | | | | | | | | | Support HPPA kernel builds. Notes: - HPPA 2.0 supports 32-bit and 64-bit kernels (HPPA 2.0 userland remains 32-bit for now as toolchain support isn't there yet for 64-bit). I've decided to only accommodate 64-bit kernels here unless/until someone requests & can help figure out an acceptable solution for 32-bit kernels for HPPA 2.0. - HPPA 1.x should be fine as there's no need for a cross-compiler there, unlike HPPA 2.x for 64-bit (sys-devel/kgcc64). It should Just Work, but not tested. Not adding a BDEPEND on sys-devel/kgcc64 as it's unclear how to do this cleanly only for HPPA 2.0. Tested on RP3440 and C8000.

* dist-kernel-utils.eclass: Introduce eclass for helper functionsMichał Górny2021-01-131-3/+3
| | | | | | | | | | | | Move some of the utility functions from kernel-install.eclass into dist-kernel-utils.eclass, in order to permit using them without having all kernel-install phases exported. This will be used in order to support rebuilding initramfs in sys-fs/zfs-kmod. Since the eclasses are used only by dist-kernel project eclasses and ebuilds, update the function prefix while moving them. Signed-off-by: Michał Górny <mgorny@gentoo.org>
