Summary:	Directory to install third-party binary kernel modules for kernels %{kernelversion}.%{patchlevel}.x
Group:		System/Kernel and hardware

%description -n kernel-%{kernelversion}.%{patchlevel}-rosa-flow-abi
This package contains a directory to install third-party binary kernel modules for kernels %{kernelversion}.%{patchlevel}.x.
Some vendors provide binary-only kernel modules. They can put them into /lib/modules/%{kernelversion}.%{patchlevel}-rosa-flow-abi.
kmod tools will find them for kernels 5.4.x of "generic" and "nickel" flavours
but there is no guarantee that these modules will load and work correctly on
newer or older kernels then the ones they were build against.

We call this "flow ABI" because most ABIs are not changed between %{kernelversion}.%{patchlevel}.x releases,
but there are no specific guarantees. ABI may evolve and change.
We highly recommend to use DKMS and build third-party kernel modules from source for every kernel!
This package does nothing, just owns a directory for third-party binary kernel modules.

# Compressing modules
%if %{with compress_modules}
# Tested on /lib/modules/5.10.34-generic-2rosa2019.1-x86_64, the results are the following:
# * decompressed: 266.3 MiB
# * xz -9 --extreme: 67.8 MiB
# * zstd --ultra -22 without training: 73.5 MiB
# * zstd -6 without training: 79.6 MiB
# * zstd --ultra -22 with training: 66.3 MiB (the winner!)
# Training takes only a few minutes, make it here in place with current zstd and kernel modules.
# But! Decompressing also requires a dictionary for zstd, that will be too complex, so not using training :(
# We already use zstd in dracut to compress initrds quickly and with good compression ration.
# Testing speed of loading modules:
# `time modinfo bcache.ko.xz` took 0,048s, `time modinfo bcache.ko.zstd` took 0,014s (for multiple times)
# find /lib/modules/5.10.34-generic-2rosa2019.1-x86_64 -type f -name '*.ko.zst' > /tmp/zst.list
# time { for i in `cat /tmp/zst.list`; do modinfo $i >/dev/null 2>&1; done ;}
# took ~31-40s, with disk cache (2+ runs) ~33s
# find /lib/modules/5.10.34-generic-1rosa2019.1-x86_64 -type f -name '*.ko.xz' > /tmp/xz.list
# time { for i in `cat /tmp/xz.list`; do modinfo $i >/dev/null 2>&1; done ;}
# took 43-47s, with disk cache (2+ runs) ~42s, +21%%
# zstd-compressed initramfs image initrd-5.10.34-generic-1rosa2019.1-x86_64.img with *.ko.xz is 56,3 MiB
# zstd-compressed initramfs image initrd-5.10.34-generic-2rosa2019.1-x86_64.img with *.ko.zst is 58,4 MiB (+3.6%%)
# /lib/modules/5.10.34-generic-1rosa2019.1-x86_64 (*.ko.xz) is 78,1 MiB
# /lib/modules/5.10.34-generic-2rosa2019.1-x86_64 (*.ko.zst) is 83,9 MiB (+7%%)
# When zstd is compressing cpio (initrd image) with zstd-compressed kernel modules inside it, does it recompress data?
# It is not easy to make a choice between zstd and xz for kernel modules... Disk space (and so speed of installing
# RPM packages) is not much bigger, we do not try to support super low end devices, operation speed is a bit better.
# I have not seen measurable difference in startup time according to systemd-analyze.
# Note that decompression after zstd --ultra -22 will consume more memory than after zstd -6, see commit message in
# https://github.com/torvalds/linux/commit/73f3d1b48f5069d46b. I did not benchmark -6 vs -22 in runtime.
