[ Test case ]
Install the latest linux-6.17 kernel on Noble:
$ sudo add-apt-repository ppa:canonical-kernel-team/ppa3
$ sudo apt install linux-generic-hwe-24.04-edge
Install lttng-modules-dkms:
$ sudo apt install lttng-modules-dkms
+ Module built and installed successfully.
+
Load the module:
$ sudo modprobe lttng-test
+ Module loaded successfully.
+
The same procedure can be repeated on linux-6.8 to test for possible
regressions.
+
+ Install the latest kernel on Questing and Resolute:
+
+ Install lttng-modules-dkms:
+
+ $ sudo apt install lttng-modules-dkms
+
+ Module built and installed successfully.
+
+ Load the module:
+
+ $ sudo modprobe lttng-test
+
+ Module loaded successfully.
[ Fix ]
Backport upstream patches from lttng-modules
(https://git.lttng.org/?p=lttng-modules.git):
-
[ Regression potential ]
We may experience regressions in systems that are using the lttng-
modules drivers, especially with kernels >= 6.8 kernel.
