Manu, will you remove them? There is actually two problems with my commits, the first one is that you cannot compile a kernel with iwm firmware in it, rea@ sent me some patches a few weeks ago that solves that so this will be fixed soon-ish. The second is people loading from loader who updates their box from 13/14 to current, as make installkernel doesn't install the firmware anymore it will fail, removing iwm_load from loader.conf for the upgrade phase is the way to go I think as I don't see any other way. > commit af0a81b6470aba4af4a24ae9804053722846ded4 > Author: Emmanuel Vadot <manu@FreeBSD.org> > AuthorDate: Thu Dec 12 17:13:58 2024 +0100 > Commit: Emmanuel Vadot <manu@FreeBSD.org> > CommitDate: Mon Dec 16 10:44:47 2024 +0100 > > iwm: Stop shipping firmware as kernel module > > Since we can load raw firmware start shipping them as is. > This also remove the uuencode format that don't add any value and garbage > collect old firmwares version. > For pkgbase users they are now in the FreeBSD-firmware-iwm package. > > > > >> Being able to build iwm in the kernel rather than a module is broken. > >> > >> Now, the real issue(s) are that iwm needs firmware to initialise, and the firmware needs to exist, and thus it needs access to the rootfs for firmware_get() to find the now binary files in /boot/firmware instead of the kernel module old way, and that whole pipeline is broken if it's loaded at boot time or included in the kernel directly. There isn't a nice way to defer the firmware load attempt until /after/ rootfs is up. > > The answer is not to load it from loader anymore really but let devd do > it's job. Yes agreed and I've done that for quite some time but it seems that we advertize for a long time that loading wifi module from loader wasthe way to go so a lot of people were bitten by this. > That is monolithic kernels + firmware are still the problem but I am not > generally thinking this is the problem here. > > But yes, there would also be ways for firmware laod to be defered but > that's also a different story.
