2022-01-24libperfmgr: support mask as voteWei Wang
For a system have following hints: * Hint A masks hint X, Y; * Hint B masks hint Y, Z; Consider a sequence of below: * Hint A activates - masks X, Y * Hint B activates - masks Y, Z * Hint A deactivates - unmasks X, Y With current implementation, both X and Y are unmasked, Z is masked in the end. This CL changes makes libperfmgr remember which hint mask/unmask. So after this change, in the end, X is unmasked, Y and Z are masked.

2021-02-23libperfmgr: introduce HintActionWei Wang
Provide flexibility to make power hint cross referenced. With proper configuration, we can mask some power hint if another power hint is on. e.g. we can stop launch hint under thermal conditions or battery saver mode etc. or we can end the current active hint earlier if another hint comes, e.g. display idle. below configuration is added into unit tests { "PowerHint": "MASK_LAUNCH_MODE", "Type": "MaskHint", "Value": "LAUNCH" }, { "PowerHint": "END_LAUNCH_MODE", "Type": "EndHint", "Value": "LAUNCH" }, { "PowerHint": "DO_LAUNCH_MODE", "Type": "DoHint", "Value": "LAUNCH" } Bug: 180923613 Test: /data/nativetest64/libperfmgr_test/libperfmgr_test Change-Id: I6e3fac0d8768b271955b1a474b02b934666c154a
