** Description changed: [Impact] Azure requested cppc_cpufreq to be available by default (without need to - install modules-extra) on linux-azure and linux-azure-nvidia kernels 6.8 - and newer kernels. Address this by moving it to linux-modules. + 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 in linux-azure-nvidia package, and to azure.inclusion-list for the linux-azure package. Note that this has been fixed in linux-azure-nvidia as of linux-azure- nvidia - 6.8.0-1025.27. For linux-azure, the fix needs to be applied to Noble, Plucky, and Resolute. Questing can be skipped due to the commit - at [1], which completely consolidates linux-modules and linux-modules- - extra due to improvements to zst compression as outlined in LP: #2042831 - [2]. All the modules can be compressed smaller than the original size of - the linux-modules set, so there's no longer a benefit to the separation. - If the patch at [1] is applied to Resolute before the one for this LP - bug is applied, this patch can be dropped for Resolute. + at [1], which consolidates linux-modules and linux-modules-extra due to + improvements to zst compression as outlined in LP: #2042831 [2].
