https://bugzilla.kernel.org/show_bug.cgi?id=216347 --- Comment #4 from madcatx@xxxxxxxx --- I modded the driver to log the events, here's the output. Note that I log all events and have an extra output for the THM event so the output is a bit noisier that necessary. [ 110.307214] TPACPI event id 24626 * Manual switch to performance [ 110.307221] TPACPI event THM_CSM_COMPLETED [ 110.308287] TPACPI event id 4114 * Drop to low power [ 125.374888] TPACPI event id 24626 [ 125.374894] TPACPI event THM_CSM_COMPLETED * Manual switch to performance [ 178.560859] TPACPI event id 24626 [ 178.560862] TPACPI event THM_CSM_COMPLETED * Drop to low power [ 321.588092] TPACPI event id 24626 [ 321.588100] TPACPI event THM_CSM_COMPLETED * Manual switch to performance [ 340.418211] TPACPI event id 24626 [ 340.418215] TPACPI event THM_CSM_COMPLETED * Manual switch to performance [ 344.953610] TPACPI event id 24626 [ 344.953614] TPACPI event THM_CSM_COMPLETED * Drop to low power [ 350.357321] TPACPI event id 24626 [ 350.357328] TPACPI event THM_CSM_COMPLETED * Manual switch to performance [ 352.865566] TPACPI event id 24626 [ 352.865573] TPACPI event THM_CSM_COMPLETED * Drop to low power [ 362.030351] TPACPI event id 24626 [ 362.030355] TPACPI event THM_CSM_COMPLETED There doesn't seem to be anything hammering the toggle, it just switches itself back to "low-power". There doesn't seem to be any apparent pattern that would provoke this. All I can tell is that the power profile seems to switch itself back from "performance" to "low-power" after some time. It can take anywhere from 5 to 70 seconds for this to happen. It also looks like the "balanced" profile seems to stick but I need to verify this better. -- You may reply to this email to add a comment.
