description |
Some facts:
- The linux kernel has supported loading xz compressed firmware since 5.3
- The size of /lib/firmware in impish is ~650Mb (and growing)
- The compressed size of firmware could be ~230Mb
It would be nice to install compressed firmware to save space.
Here are the plans from the Fedora project:
https://fedoraproject.org/wiki/Changes/CompressKernelFirmware |
-- initramfs-tools
[Impact]
* linux supports xz compressed linux-firmware which saves disk space. In focal, initramfs-tools only knows how to included uncompressed firmware files (even when kernel supports loading compressed ones). Newer releases of linux-firmware may use compressed firmware files only, in such cases it would be nice for focal's initramfs-tools to support compressed firmware files in case of partial or incomplete upgrades (i.e. linux-firmware force installed or upgraded, without newer initramfs-tools). The proposed changes to initramfs-tools are backwards and forwards compatible, they prefer to include uncompressed firmware files; and if missing, include compressed firmware files in their uncompressed form. Thus maintaining compatibility with any kernels, irrespective of compressed/uncompressed firmware inputs.
[Test Plan]
* Compress all files shipped by linux-firmware with xz
* Rebuild initrd
* Check that all the same firmware files are still included in the initramfs, in their uncompressed form as before
[Where problems could occur]
* This SRU is precautionary to prevent accidental installation of compressed linux-firmware from generating incorrect initramfs. It should be noted that whilst initramfs-tools would create a compatible initramfs with any kernels, pre-v5.3 kernels do not support xz compressed firmware files at runtime. Mixing this new initramfs with compressed firmwares and pre 5.3 kernels may lead to expectations of supporting compressed firmware files with them only working at initrd stage and not at runtime.
