Description of problem: (Unused) firmwares use too much disk space. $ rpm -qi iwl7260-firmware Name : iwl7260-firmware Epoch : 1 Version : 25.30.13.0 Release : 83.fc28.1 Architecture: noarch Install Date: seg 21 mai 2018 10:35:46 -03 Group : Unspecified Size : 59429660 That's nearly 60MB in wifi firmwards! Meanwhile, if I compress these with xz, I get them down to: $ du -sc iwlwifi 11252 iwlwifi 11MB, 16% of the original. Version-Release number of selected component (if applicable): 4.16.3-301.fc28.x86_64 How reproducible: Always
Erm AFAIK the kernel's builtin firmware loader does not support loading compressed firmwares, so I don't think this is doable atm.
That may very well be the case. I have no info on whether it is already supported or not.
We do have zlib in the kernel though, and/or could happily fall back the the userspace loader for *some* images...
(In reply to David Woodhouse from comment #3) > We do have zlib in the kernel though, and/or could happily fall back the the > userspace loader for *some* images... I've been involved in some upstream firmware loader discussions and upstream really sees the userspace helper as obsolete. Not that they are going to kill it anytime soon, but still.
This bug appears to have been reported against 'rawhide' during the Fedora 29 development cycle. Changing version to '29'.
This message is a reminder that Fedora 29 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 29 on 2019-11-26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '29'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 29 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.

So as of 5.3 the upstream kernel supports this with the CONFIG_FW_LOADER_COMPRESS option. We do have some work to do to investigate how it handles the symlinks for modules etc so we're not quite there yet but it's on my radar.
I'll be implementing this as a change in Fedora 34 *** This bug has been marked as a duplicate of bug 1888831 ***
