Re: upstream linux cannot achieve package C8 power saving

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



I contacted the Ubuntu developers to see if they were ok with using
their patches.

They advised the patches were outdated and further development was
under discussion.

The current patches work and would benefit Linux users until something
better comes along.

Would you like me to proceed with the formal patch still ?
