Hi, short summarize from irc: https://fedoraproject.org/wiki/Changes/CompressKernelFirmware xz -C crc32 is the only supported mode mkinitcpio needs to be patched: https://bugs.archlinux.org/task/72263
From my side unknown, if dracut and booster can handle compressed firmware files.

Hi, according to google in 5.3 the xz compression was introduced so all kernels we ship should support it. greetings tpowa

Hi guys, lately did a lot of archboot hacking and stumbled over our firmware package. It needs installed 750 MB, download size is 130 MB. I tried to get it smaller and uploaded the archboot-linux-firmware
for my purposes. Our linux kernel needs only 180 MB installed size, download size is about 37 MB. Wouldn't it make sense to provide for each kernel we ship, a separate firmware package? Just my 2 cwnts, greetings tpowa
The method used there wouldn't produce a usable firmware package for me. For example, `modinfo -F firmware iwlwifi` lists `iwlwifi-Qu-c0-hr-b0-64.ucode` but linux-firmware does not contain that file. The driver will fall back to the next lower version, `iwlwifi-Qu-c0-hr-b0-63.ucode`, which is in linux-firmware but not in
modinfo output.
I think the best we can do is split some of the more obscure vendors

have large firmware sets, like Netronome, Qualcomm, Mellanox, Marvell, Cavium, QLogic and NXP.
I second this, the biggest firmware sizes are from these fancynetwork equipemnt folks such as netronome. An alternative is enabling xz compression for the firmware itself this should save space as well, but it depends on support in the LTS kernel.
Can't we do both? Enable xz and split the larger firmwares? Or LTS don't have plans to support xz for firmware?
