2020-07-27fix uninitialization issue in JankTrackerZhiyin Luo (罗植尹)
We should initialize mSwapDeadline in JankTracker, or it can be a very large randomized value and then makes jank tracker not collect concrete jank type of frames appropriately as expected. Bug: 161656795 Test: run cts -m CtsIncidentHostTestCases -t com.android.server.cts.GraphicsStatsValidationTest#testJankyDrawFrame Change-Id: I057a50a74502918619204f9164f6a954f8e9c5de Merged-In: I057a50a74502918619204f9164f6a954f8e9c5de (cherry picked from commit 7a0d224756195ce81875db0b481a77b87f860dd3)

2019-05-27Avoid fake high input latency while vsync driftingGao Shuo
Usually isTrippleBuffered should be true when mSwapDeadline bigger than IntendedVsync. However, vsync could be drifting on some platforms, which make isTrippleBuffered to be true and report a fake high input latency. So add a small threshold to avoid this case.

2018-09-14Don't run comparisons on non-jank framesJohn Reck
Unclear why mSwapDeadline doesn't already account for this, but the handling of vsync phase offsets may be throwing things off a bit. For now just do the simple fix. Bug: 109894489 Test: builds, patch was verified by reporter Change-Id: I5a6f25ceac4986d366293fe7b5e3af64a326114c
2018-04-20Add socket listener to statsd. And remove Davey atom.Yao Chen
+ The socket listener is behind a flag. It's disabled until we get sepolicy changes in. + Data parsing code is from logd, because we use the same format. + Removed Davey from JankTracker because it violates our new sepolicy Test: manually Bug: 78239479 Change-Id: Ib17729fbc362cdb13385f780e2d636a95adf9bc3
2018-03-19Revert "Revert "Break down jank between frame drops vs. triple buffered""John Reck
This reverts commit a6d8fbf4ea634f5f605b2b7db3ca98975f8625b5. Fixes an out-of-bounds read in COMPARISONS by switching up how comparisons works. Instead of requiring all jank types to have an associated COMPARISON's entry, which kHighInputLatency and kMissedDeadline don't, instead have each COMPARISON indicate which JankType it applies to so it can be independently sized from JankTypes. Bug: 70220906 Bug: 75566601 Test: launching & using maps works Change-Id: I7fd90daeb320b4627e42c3418c89726d860998c1

This reverts commit 09979fbee7201b46158c2c033194529e4284ea13. Reason for revert: Based on stacktraces and change history, I think this is causing a cluster of P crashes. https://b.corp.google.com/issues?q=(%22android%22%20%22:uirenderer::JankTracker::finishFrame%22) Bug: 75566601 Bug: 75811585 Bug: 75407175 Bug: 75736222 Bug: 75391447 Bug: 75659839 Change-Id: I59a8c2d8906d347210c77fb3628f5801bc299bfb

2018-02-26Updates jank metrics in statsd to include uid.David Chen
We need the uid to easily know which app to blame for producing the frame with excessively long render time. Also updates the errors so it's more obvious if the error is in parsing versus the other checks. Test: Test that statsd builds and verified CTS test still passes.

2017-11-13Fix leak of FILE* in dumpingJohn Reck
Avoid fdopen as fclose, which frees the FILE*, will close the FD which we don't want. Just normalize on dprintf instead, and we can add buffering if it turns out to matter at some point Test: ran 'dumpsys gfxinfo framestats' in a loop while observing PSS Change-Id: I7808753641aa1055cfdf570c3e017017f11f1dee

2017-07-05Split out jank data from policyJohn Reck
Move ProfileData out to its own file with helper accessors. This keeps policy (what is/isn't jank) outside of the data storage. Also use lambdas to iterate over the histogram to make it nicer for dumping & proto-ifying. Test: hwui_unit_tests pass & jank data still dumps Change-Id: I88488369ec77590a2867f51128e65bb786aa34e6

2017-02-21Overhaul GraphicsStatsServiceJohn Reck
* LRU cache of recently-used is dead, replaced disk storage * ASHMEM size is read from native by the system service, no longer requires keeping a sizeof() in sync with a constant in Java * Supports dumping in proto format by passing --proto * Rotates logs on a daily basis * Keeps a history of the most recent 3 days Bug: 33705836 Test: Manual. Verified log rotating works by setting it up to rotate every minute instead of day. Confirmed /data/system/graphicsstats only has the most recent 3 entries after several minutes Change-Id: Ib84bafb26c58701cc86f123236de4fff01aaa4aa

2016-07-29Teach JankTracker about new swap behaviorsJohn Reck
Bug: 30440166 If we are using HWC2, there's a change in timing when in triple buffering with the pipelined offsets. This changes JankTracker to recognize that and silently erase that from the total duration Change-Id: Ib1fd4209070f17dbd2baed707c8cf73fb11c3cf2
2016-04-15Switch JankTracker to FrameInfo::duration()John Reck
Fixes: 27533462 FrameInfo::duration() will remove time spent waiting in the queue from the duration. This is desired because that time is otherwise accounted for by the previous frame, so we don't want to double count it. This shows up mostly in TestSceneRunner & shadowgrid2 due to a combination of slow frame times and continous rendering. Change-Id: I27c42d5c24d266de4ada8ea00ec9164d518754f8

2016-03-31Expand JankTrackerJohn Reck
Bug: 27922347 * Dump the full histogram * Expand the histogram to have a slow-frame section with large 50ms buckets to raise the cap to 5s to give more insight into system-health * Stop excluding first-frame metrics as we want to include those in our global tracking. Automated tests already filter these out by doing resets before running anyway. Change-Id: Idaba8aad591f59d10a6477b11efc0767ff715083
