[SRU][F/H/I] Add MT7921 wifi fw

[AaronMa]

SRU justification:

[Impact]
No support for MT7921 wifi card.

[Fix]
MT7921 needs both driver and firmware, driver is almost ready,
add firmware first, then get driver bug fixed later.

[Test]
Verified on hardware, cold boot system wifi works fine.
Reboot make it fail, but I will fix it in SRU of kernel patch.
After that, it works fine.

[Where problems could occur]
The MT7921 wifi may not work.

[Brian Murray (brian-murray)]

It looks to me like this is an update of an existing driver, mt7921, which it seems to me might have existing users. If that's the case will rebooting causes WiFi to fail for hardware that's already supported?

[AaronMa (mapengyu)]

Hi Murray:

That bug of rebooting is fixed by bug#1936790

[Chris Halse Rogers (raof)]

Specifically: this is a straight addition for focal, but is an update of existing firmware for hirsute. Does the existing hirsute kernel have any driver that uses that firmware, or is that firmware unused in hirsute?

If it is unused in hirsute then updating it is less risky.

[Chris Halse Rogers (raof)]

Hello AaronMa, or anyone else affected,

Accepted linux-firmware into focal-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/linux-firmware/1.187.16 in a few hours, and then in the -proposed repository.

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Timo Aaltonen (tjaalton)]

according to bug 1936790 mt7921 driver is only on 5.13 and up

[Chris Halse Rogers (raof)]

In conversation with Timo we've verified that the relevant firmware files modified here are currently unused in hirsute - there are no hits for them in the existing mt79 driver.

Accordingly, this is not expected to affect any existing hirsute systems.

Bluetooth isn't working for me either. I'm using Hirsute + linux 5.14 RC6. I needed to upgrade to linux 5.12.19 to get wi-fi working and then tried kernel versions 5.13.9/5.14-rc6. I have installed linux-firmware version 1.197.3.

[AaronMa (mapengyu)]

Looks the card doesn't work on ASUS, could you please upload the "sudo lspci -vvvnn", "lsusb -v" and dmesg?

[bohb (pop-os-user-pls-dont-kill)]

I should probably mention that the card is working on Windows. I believe that I have done most of the things necessary for a proper dual boot, I have disabled hibernation entirely, I have disabled fast boot in the BIOS, and I always shut-down Windows with the command "shutdown /s /f /t 0" from an admin prompt.

Hi bohb,
It should be fixed by:
https://git.kernel.org/pub/scm/linux/kernel/git/bluetooth/bluetooth-next.git/commit/?id=2cdff8ca4c8414401bcbc9701229e971797b1340

Please wait for it is applied by upstream.

[bohb (pop-os-user-pls-dont-kill)]

Thanks for the fix, can't wait :)
