Since the update to the most recent version of firmware 18/9/2020, the kernel says it failed on 2 firmware (see above), neither of these firmwares are available in /lib/firmware. I do not use saved config so all firmwares are compiled and installed.
I presume they are new modules because in my previous versions they were not, and the existing needed firmwares need them. All other firmware from iwl is present and loaded. In previous versions this was not a problem. I think some dependency is changed and the new modules were not included in the packet.
This is my Linux-firmware :

Hopefully someone can correct this ?

I see you download all firmware and then hope one of those fits your hardware. I do it the other way around, I get the firmware which matches my hardware, the lottery element is missing in my method. You have my permission to use my method until your way starts working again.

poe_1957,

All of dmesg would be useful.

If your iwlwifi driver is built into your kernel, its firmware must be too as it will be loaded before root is mounted.
If iwlwifi is a module, it will be loaded when the module is loaded. That may mean that the firmware needs to be in your initrd.

Downloading all packaged firmware is easy via the Gentoo firmware package, and for most people, provides what they need without the need to research what exactly they will need. It is not the most space efficient approach, but it is very simple and quick.

[poe_1957]

I started first with selecting every firmware I needed and everything was ok (NeddySeagoon you have my config already seen), but he responded withy the latest upgraded firmware (september) to say I need those ucodes which I previously not needed in previous versions of linux-firmware (june, july, august 20)and those did not give me a problem .
So I added them( the missing new cc-a0-56 and the yoyo-debug.bin) in the kernel-buildin by drivers--> loading firmware. I recompiled tyhe kernel and then he said he could not find it. So I searched /lib/firmware but I did not found the firmware.
So i removed saved-config in hope that they would show up. NOPE. And that is the situation i am in now.

The firmware he needs is NOT in the gentoo Linux-firmware. See my post I miss :

iwlwifi-cc-a0-56.ucode is not in Linux-firmware where it should be.
iwl-debug-yoyo.bin is not in Linux-firmware where it should be.

I post more dmesg tomorrow but I doubt it would clear up anything since it is clear that the current version does not contain the modules needed.

@Hu

It depends on what Gentoo is for you. For me it is a [great] idea and help to build my Linux. In other words, I build my Linux my way, and I use Gentoo way only if it suits me. I do not let it restrict me, if there is something more rational and less bloated then I do not feel Gentoo forcing me (love that!). What exactly is the purpose of your post? Who are you addressing? General public? I did not say everybody has to do it my way.

The firmware is loaded and the device is functional. Not the latest which is not available, yet.
I do not think iwl-debug-yoyo.bin is needed for normal operation, it looks like something developers could use.

Stripped for security? Oh my ... MAC is layer 2, how could it be dangerous to publish.

[NeddySeagoon]

Buffoon,

Thats erring on the side of caution. The internet never forgets.

According to https://wireless.wiki.kernel.org/en/use ... 0#firmware the AX200 wants iwlwifi-cc-46....

[poe_1957]

@Daggystyle :

Your solution worked perfectly, I downloaded and unpacked it and I moved it to /lib/firmware, added in the kernel, recompiled and the problem was gone. I did not need for the iwl-debug-yoyo.bin. As Buffoon said I do not think iwl-debug-yoyo.bin is needed for normal operation, it looks like something developers could use.

Question remain : can someone inform the maintainer of Linux-firmware to add iwlwifi-cc-a0-56.ucode to add it ?

For me this problem is resolved but I can image some other people would stumble on the same problem.

[CaptainBlood]

I guess opening a bug report at Gentoo bug report could help.
Seems like most devs only care for such report, not what is said on the forum.
Thks 4 ur attention, interest & support.

Intel Wifi is known to actively advance the allowable versions of firmware releases even before they are published. The message is normal and expected until it is released.

The driver will try known working firmware versions from greatest to least. So long as one is found, the device will work albeit with Non-existent files being a little verbose in dmesg.

The point is the device works and will accept new firmware when it is released upstream.

I would agree with your point if the software incorporated in the app-sys/linux-firmware did not ask for the missing module.But in fact it needs it to work.
I am still from the opinion if you upgrade the software with a new version you take ALL the necessary pieces needed for the working of the device. In this case is it is not.
Just adding the iwlwifi-cc-a0-56.ucode to the sys-app/linux-firmware solves the problem.
I think it is just forgotten to add it.

my 2cents,

[Etal]

Where did iwlwifi-cc-a0-56.ucode come from, though? Both in linux-firmware, and on Intel's firmware download page, the latest one is iwlwifi-cc-a0-46.ucode

Intel hardcodes firmware version numbers into the iwlwifi driver for each type of device and often list several even before they are released. They don't necessarily post them on their website.

I would agree with your point if the software incorporated in the app-sys/linux-firmware did not ask for the missing module.

There is no "software" in sys-apps/linux-firmware. The kernel driver requests many different firmwares that the kernel itself should load and when it finds a supported one, it is happy.

If you can point to where iwlwifi-cc-a0-56.ucode exists, then everyone would be happy. It certainly does not yet exist in the upstream repository.

[poe_1957]

As you say it loads from intel.
In september the code was available from their site. Now in october it seems they have removed them again and rolled back their drivers to the previous situation that worked ok.
With a new reload of the firmware it was back to 'normal' situation. So you can close the bug. After all it seems that it orgin was then Intel and that they corrected it.
Now everything is working fine again as previous.

It seems it was a premature release of Intel. Now with your explication I understand better the working of the ucode.
