We planned to get these changes upstream at first to have the foundation for TPC in the mac80211, and then develop driver implementations and TPC algorithm on top of this once all is reviewed, approved and upstream. The ath9k tpc support is currently not upstream-ready but can be in a next version. For testing the actual TPC support I modified minstrel’s debugfs to be able to set fixed tx-power per STA. I think we can develop this series further to come up with fully working driver implementation and a TPC algorithm if you think that would be better. Else we could also provide at least a debugfs patch to be able to set fixed tx-power per STA. Greetings Jonas > On 29.
