Vulkan occlusion query demo

Overview

This repo contains the source for an applicaiton that renders a triangle using Vulkan, saves the output as a PNG, and outputs the number of shaded fragments via an occlusion query. This applicaiton is used to debug turnip occlusion queries on Chrome OS.

Instructions

Enter the CrOS chroot and set up the boards you want to test against (setup_board --board=${BOARD}).
Emerge Vulkan, mesa, and libpng to the device under test (emerge vulkan-loader media-libs/mesa libpng && cros deploy ${IP_ADDR} ${PACKAGES}).
make shaders
target={local, atlas (i915), cheza (adreno)} make
