hello

I have bought a new MSI Laptop with wifi controller Mediatek:

there is 2 news infos about kernel
theorically the driver mt7921e is usable from kernel 5.12
in my "15.5 openSUSE distro this driver is present

i have tryed to start driver with command :
miguel@localhost:~> sudo modprobe --first-time mt7921e

the driver seems to be loaded the next command seems to confirm that :
miguel@localhost:~> sudo lsmod | grep -i mt79
mt7921e 90112 0
mt76_connac_lib 40960 1 mt7921e
mt76 90112 2 mt7921e,mt76_connac_lib

cfg80211 1048576 4 mt76,mt7921e,mac80211,mt76_connac_lib

After that i restarted the networkManager service and nothing change wifi is not enabled and the lspci command donā€™t show driver info.

Has someone some solution for my problem
Thanks in advance

@micalmar:

First, welcome to the openSUSE Forums.

Checking the content of the openSUSE RPM package ā€œkernel-firmware-mediatekā€, it seems that, the firmware for the MT7921K isnā€™t currently available.

  • Leap 15.5 Kernel version: 5.14.21

But, the Linux Kernel has this information: <https://wireless.wiki.kernel.org/en/users/drivers/mediatek>.

  • The MT7921 as such is supported as follows:
    PCIe from Kernel version 5.12+
    SDIO from Kernel version 5.16+
    USB from Kernel version 5.18+

Therefore, you can either wait a few months until the openSUSE Kernel backport team supply the MT7921 firmware for the Leap 15.5 (SLE) Kernel or ā€“

  • you could try Tumbleweed.

Thanks a lot for your fast answer

the live CD of Tumbleweed manage the wifi controller.
wait and see

Not the name of the Wifi Controller is important, only the ID is important and not shown by your commands.

So please post:
/sbin/lspci -nnk | grep -iA3 net

modinfo shows, what firmware is needed and which ID are ready for this driver:

Checking the content of the openSUSE RPM package ā€œkernel-firmware-mediatekā€, it seems that, the firmware for the MT7921K isnā€™t currently available.

Its in the OSS Repo:

I messed up ā€“

The Mediatek MT7921 drivers, are supplied by the kernel-default-extra and kernel-default-optional packages:

 > rpm --query --whatprovides /lib/modules/5.14.21-150500.55.7-default/kernel/drivers/net/wireless/mediatek/mt76/mt7921/*
kernel-default-extra-5.14.21-150500.55.7.1.x86_64
kernel-default-extra-5.14.21-150500.55.7.1.x86_64
kernel-default-optional-5.14.21-150500.55.7.1.x86_64
kernel-default-optional-5.14.21-150500.55.7.1.x86_64
 >

On the other hand, the mt7921e/u/s drivers seem to be calling MT7922 and MT7961 firmware (modinfo output).

Therefore, the question is ā€“ ā€œIs that firmware being loaded?ā€

The systemd Journal will probably be of little help:

 # journalctl -b 0 --no-hostname --output=short-monotonic | grep -i 'firmware'
[    0.100998] kernel: Spectre V2 : Enabling Speculation Barrier for firmware calls
[    0.329235] kernel: ACPI: [Firmware Bug]: BIOS _OSI(Linux) query ignored

[   21.778792] iscsiadm[1778]: iscsiadm: Could not get list of targets from firmware. (err 21)
 #

The information under ā€˜/sys/firmware/ā€™ may also be of not much help.

# find /lib/firmware -atime -1

and ā€“

# find /lib/firmware -atime -2

are also not much help.

Bottom line:

You cannot query for ā€œcurrently loadedā€ firmware, because firmware doesnā€™t necessarily remain in system memory. It is often uploaded to some chip in some device outside the system. Most drivers will load a firmware file into a kernel buffer, use that buffer to program the device, then discard the buffer without keeping any record of what the file was. Some drivers do log their firmware loading to the kernel log, but that is by choice of whoever wrote the driver; itā€™s not universal.

And thinking about this issue, the only time Iā€™ve ever seem Firmware being logged in the boot Journal is, when a required Firmware either couldnā€™t be found or, didnā€™t load ā€“ for whatever reason ā€¦
