* power: Handle launch and interaction hints for perf HAL platformsBeYkeRYkt2019-10-231-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Author: BeYkeRYkt <beykerykt@gmail.com> Date: Thu Dec 13 06:42:35 2018 +0900 power: Handle launch and interaction hints for perf HAL platforms * MP-CTL does not handle POWER_HINT_INTERACTION and POWER_HINT_LAUNCH directly. Requests for processing are sent by Qualcomm BoostFramework (QPerformance) at the framework service level. Since we do not have BoostFramework, process POWER_HINT_INTERACTION and POWER_HINT_LAUNCH in PowerHAL to ensure a sufficient level of performance. * For proper operation, perfboostsconfig.xml file is required.

The hint ID corresponding to SCROLL_PREFILING only takes into effect for a default timeout value of 80 ms (as found in perfboostsconfig.xml), while the duration value in the process_interaction_hint function runs for a much longer time, from 1500 ms up to 5000 ms (bounds of kMinFlingDuration and kMaxInteractiveDuration). During the period of time, when the timeout value has elapsed and current time is less than duration, another interaction hint cannot be processed. Therefore, if the user decides to scroll during this period, high frame drops can be experienced as the CPU freq isn't raised by processing another hint to account for this additional scrolling. By only using SCROLL_VERTICAL, fluidity can be maintained, improving user experience. Furthmore, kMinInteractiveDuration has been lowered to 400 ms for some platforms as it is more than sufficient to maintain fluidity (minimal frames dropped) while scrolling.

Using a fixed duration for this perflock has two shortcomings: * perflock can be held for too long, causing the CPU freq and other resources to be boosted for too long even if the application has finished launching, resulting in excessive battery drainage * perflock can be held not long enough if it takes more than the timeout time to finish launch The framework sends out a powerhint for both when launch starts and when launch ends. The launch finish hint can be used to signal when to release the perflock.

* power: perform_hint_action: return an error codeCorinna Vinschen2019-10-231-34/+34
| | | | | | | | | | | So far the caller never knows if setting the hint actually worked. This leads to a potential disconnect between the actual setting and the UI because set_power_profile simply assumes perform_hint_action worked. Return an error code or 0, so the callers can check for success. Change-Id: I180a367e9d8581a63dfa703046b37bc5cae8c6cb Signed-off-by: Corinna Vinschen <xda@vinschen.de>

* power: fix sysfs_read/sysfs_write usageCorinna Vinschen2019-10-231-6/+6
| | | | | | | | | | | | * The incoming path to sysfs_read/sysfs_write should be const, as in open(2) call. * Redefine scaling_gov_path as const pointer array. * Since sysfs_read works on a simple absolute path anyway, make sure the scaling_gov_path paths *are* absolute. Otherwise the code only works if Power HAL has / as CWD, which is a bit fragile. Change-Id: I70c08f8137842569514bcb3f6e0617d46044e6ab Signed-off-by: Corinna Vinschen <xda@vinschen.de>
* power: add back check for ro.vendor.extension_libraryCorinna Vinschen2019-10-231-2/+11
| | | | | | | | | | | | | | This partially reverts I0ce40bbefb8c867dda8ee5eb1f948af2106e692d, "power: Using PerfHAL API". Especially older systems don't provide libqti-perfd-client.so but this is hardcoded since the aforementioned change. Use the former code checking for ro.vendor.extension_library and try to load that library if the property exists before falling back to loading libqti-perfd-client.so.
