README

This directory contains Android-side modules related to hardware OpenGL ES
emulation. The host-side modules and documentation are in
$ANDROID_BUILD_TOP/sdk/emulator/opengl.

Note that this directory contains encoder sources that are auto-generated
with the 'emugen' host tool (see sdk/emulator/opengl/host/tools/emugen).

To regenerate them, run external/qemu/distrib/update-emugl-sources.sh,
after building the emulator from sources, this will populate the content
here with the appropriate updated source files.

You should do this whenever you update one of the *.types, *.in and *.attrib
files located under one of:

  $AOSP/sdk/emulator/opengl/libs/GLESv1_dec/
  $AOSP/sdk/emulator/opengl/libs/GLESv2_dec/
  $AOSP/sdk/emulator/opengl/libs/renderControl_dec/

or when the 'emugen' tool itself is modified.
