Title:
[SRU][O/N] Support Wi-fi and Bluetooth for Nvidia DGX Spark Platform
Status in linux-firmware package in Ubuntu:
In Progress
Status in linux-firmware source package in Noble:
Fix Released
Status in linux-firmware source package in Oracular:
Fix Released
Bug description:
[SRU Justfication]
BugLink: https://bugs.launchpad.net/bugs/2109796
These binary firmware changes are required for full Wifi and Bluetooth
functionality on DGX Spark
[Impact]
Lack of some WiFi and Bluetooth functionality on Nvidia DGX Spark
platform. Specifically, this update is required to update the power
table as required for regulatory compliance in several countries (per
MediaTek).
[Fix]
Apply the following vendor-proposed patches from upstream:
WIFI
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=8b3109069b3b381788576f137896ab5067741d3f
BT
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=ae25a3cb0fd890ad83ab058cdb13e6056908be29
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/commit/?id=7a074fed8691869665ae5b164f55d04252c605f4
[Test Case]
Verify that Wifi and BT connections can still be established with the
updated blobs, and verify that the status of the power table is
correct [0]
[Where problems could occur]
As this is an opaque binary update, this could impact all MT7925 and
MT7920 WiFi and Bluetooth devices
[Other Info]
This update originates from a support request by Nvidia
[0] MediaTek provided the following information on how to test this update:
The method of verification is to observe the status of the power table. By
connecting to 5G channel 149 under different firmware versions, it can be found
that the power is abnormal in the old version of the firmware, while it is
normal in the new version.
See the attached log for an example.
