I wonder if this can also help make the boot isos and installation images smaller ? I'm sure they haver some firmware on them. Or alternatively we could reduce the potentially quite meintenance intensive firmware culling we do at the moment. > > == Benefit to Fedora == > > Reduced on disk size of the firmware used by the kernel. > > == Scope == > * Proposal owners: > ** Add support upstream to the linux-firmware copy-firmware script to > compess the firmware and create the symlinks to the compressed > firmware > ** Enable the upstream support in the Fedora linux-firmware package to > compress the firmware at build time > ** Enable compressing firmware in packages that contain firmware used > by the kernel: eg alsa-sof-firmware, atmel-firmware, zd1211-firmware > ** Enable the CONFIG_FW_LOADER_COMPRESS kernel option (long complete) > * Other developers: > ** No impact > * Policies and guidelines: N/A (not a System Wide Change) > * Trademark approval: N/A (not needed for this Change) > > == Upgrade/compatibility impact == > > There should be no upgrade impact, the support was added to the > generic firmware loader interface in the kernel. > > == How To Test == > > Check devices that need firmware still work.
