Status in linux-firmware package in Ubuntu:
In Progress
Bug description:
[SRU Justfication]
BugLink: https://bugs.launchpad.net/bugs/2119479
These binary firmware changes are required to fix the following issues
(provided by vendor):
Release Note:
- Fix "PCIE AER: RxErr" issue
- Fix "probe request Supported Rates Listed twice" issue
- with driver patch:
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
- Send Beacon frame (with MBSS IE) to driver directly for mac80211.
- with driver patch:
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
[Impact]
Lack of some WiFi and Bluetooth functionality on mt7925 device.
Specifically, this update changes how the beacon frame with MBSS IE is
delivered to the driver, in conjunction with this kernel change:
https://patchwork.kernel.org/project/linux-
wireless/patch/[email protected]/
[Fix]
Apply the following vendor-proposed patches from upstream:
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/mediatek/mt7925?id=2ccae12c4f73bf130143ab7cc9c8546d25faac47
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/mediatek/mt7925?id=ebf45cd0f8d0e98d08e7ecfc10342735425677b1
[Test Case]
Verify that Wifi and BT connections can still be established with the
updated blobs, and verify that MBSS functionality works as expected
[Where problems could occur]
If this firmware is used without
https://patchwork.kernel.org/project/linux-wireless/patch/[email protected]/
being present in the running kernel, the firmware patch may cause a regression
in 6GHz functionality. (currently being verified).
If confirmed, I won't submit the linux-firmware patch request until this
kernel patch is accepted in the generic and derivative kernels for all targeted
releases.
[Other Info]
This update originates from a support request by Nvidia
