From 10f328c580fe1e897b51a7e4b38ee4c341d970f1 Mon Sep 17 00:00:00 2001 From: Jorim Jaggi Date: Tue, 19 Jan 2021 00:08:02 +0100 Subject: Change hwui jank detection to use deadline & gpu completion (1/2) - Use GPU finish time as well as actual deadline to determine jank rate. - Use dynamic interval to adjust for 60/90hz switching - Move frame metrics reporting into JankTracker to adjust the deadline communicated to the app when in stuffing scenario. - Adjust double-stuffing detection to be a bit more readable.
