Subject: libgui: support 64-bit BQ consumer usage
X-Git-Tag: android-x86-8.1-r1~50^2~5^2
X-Git-Url: http://git.osdn.net/view?a=commitdiff_plain;h=e2786ea5aec3a12d948feb85ffbb535fc89c0fe6;p=android-x86%2Fframeworks-native.git

libgui: support 64-bit BQ consumer usage

Add NATIVE_WINDOW_GET_CONSUMER_USAGE64.  Support 64-bit consumer
usage flags in BufferItemConsumer and GLConsumer.

In H2BGraphicBufferProducer::getConsumerUsage, however, we will
issue a warning and return 32-bit consumer usage.  We will need a
HIDL interface version bump to fix it.

Bug: 35215313
Test: manual
Change-Id: I1f8884a7db71bbdb269d05b94443ddec2ff46f8a
