From 35b48d10bc9e064201d3d54d2d476314684a7a05 Mon Sep 17 00:00:00 2001 From: Mathias Agopian Date: Mon, 13 Sep 2010 22:57:58 -0700 Subject: Add logging of various important graphics events There are 16 events logged in the event log: SF_APP_DEQUEUE_BEFORE SF_APP_DEQUEUE_AFTER SF_APP_LOCK_BEFORE SF_APP_LOCK_AFTER SF_APP_QUEUE SF_REPAINT SF_COMPOSITION_COMPLETE SF_UNLOCK_CLIENTS SF_SWAP_BUFFERS SF_REPAINT_DONE SF_FB_POST_BEFORE SF_FB_POST_AFTER SF_FB_DEQUEUE_BEFORE SF_FB_DEQUEUE_AFTER SF_FB_LOCK_BEFORE SF_FB_LOCK_AFTER all events log the buffer conserned and a timestamp in microseconds. by default the logging is not enabled, to turn it on: adb shell service call SurfaceFlinger 1006 i31 1 adb shell setprop debug.graphic_log 1 The effect is immediate in SurfaceFlinger, but applications need to be restarted.
