Iliyan Malchev	eac8965bf4	hwc: fix some race conditions ... Fix some race conditions between hwc_eventControl and the hwcVsyncThread. Bug: 7274951 Change-Id: Ic71d65918303b4cef6a379ff5397702b2b578373 Signed-off-by: Iliyan Malchev <malchev@google.com>	2012-10-04 14:03:23 -07:00
Naseer Ahmed	ff4f0254be	hwcomposer : Use sysfs to read vysnc information ... * Read sysfs entries to get vsync timestamp from kernel. * External display continues to use uevents for hotplug events * A new thread, vsyncThread is created to read and send vsync timestamps to HAL. * Disable H/W VSYNC for MDP 5.x targets until kernel changes are complete. * Synchronization is needed to make sure read() is not called by hwcVsyncThread when VSYNC is disabled.
