It has been tested by at least two people and I have been using it for at least three months with no negative issues. Th author has posted that he lacks the time to MFC but that "someone else" will have to do it. Could some committer please take a look at this one? The patch touches three files, two just to add entry points for the code. The functional code is all to /sys/dev/drm2/i915/intel_opregion.c. Other than some offsets, it applies cleanly to stable. At very least, it will fix an annoyance for some people and eliminate some messages to several mail lists (stable, questions, x1l, mobile and acpi). The patch can be found it 198551, just submitted. -- Kevin Oberman, Network Engineer, Retired E-mail: rkoberman@gmail.com
