Title:
linux-azure-nvidia: Include cppc_cpufreq in linux-modules
Status in linux-azure-nvidia package in Ubuntu:
New
Status in linux-azure-nvidia source package in Noble:
Fix Released
Bug description:
[Impact]
Azure requested cppc_cpufreq to be available by default (without need
to install modules-extra). Address this by moving it to linux-modules.
Include cppc_cpufreq module in linux-modules package instead of linux-
modules-extra so that cpufreq is enabled by default (without the need
to install linux-modules-extra).
The fix is fairly simple, add the cppc_cpufreq.ko modules to azure-
nvidia.inclusion-list.
[Test Case]
Currently cppc_cpufreq is not included in linux-modules package.
root@flavio:/home/ubuntu# uname -rv
6.8.0-1019-azure-nvidia #20-Ubuntu SMP Fri Jun 27 23:52:00 UTC 2025
root@flavio:/home/ubuntu# lsmod | grep cpufreq
root@flavio:/home/ubuntu#
root@flavio:/home/ubuntu# cat
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
cat: /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor: No such file or
directory
Preparing a test kernel with the fix and installing only the linux-
image and linux-modules package, cppc_cpufreq is present.
ubuntu@flavio:~$ uname -rv
6.8.0-1020-azure-nvidia #21 SMP Mon Aug 4 16:37:34 UTC 2025
root@flavio:/home/ubuntu# lsmod | grep cpufreq
cppc_cpufreq 262144 0
root@flavio:/home/ubuntu# cat
/sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
ondemand
[Where problems could occur]
The fix just adds a module in linux-modules package. Not any severe
regressions expected. However, those who expected to find this module
in modules-extra will not find there anymore.
[Other]
The fix is needed for linux-azure-nvidia, for Noble, 6.8.
