[ Test case ]
Install the latest linux-6.14 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa
$ sudo apt install linux-generic-hwe-24.04-wip
Install broadcom-sta-dkms:
$ sudo apt install broadcom-sta-dkms
Load the module:
- $ sudo modprobe broadcom-sta
+ $ sudo modprobe wl
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
[ Fix ]
- Apply upstream patches to properly support the new linux 6.14 ABI,
- namely the following:
+ Apply patches from broadcom-sta-dkms Plucky release enabling 6.14
+
+ * debian/patches/30-fix-version-parsing.patch
+ * debian/patches/31-6.12-unaligned-header-location.patch
+ * debian/patches/32-build-Provide-local-lib80211.h-header.patch
+ * debian/patches/33-Prepare-for-6.14.0-rc6.patch
[ Regression potential ]
+
+ We may experience regressions in systems that are using the broadcom
+ drivers, especially with kernels >= 6.8 kernel.
