DESCRIPTION="drawElements Quality Program - an OpenGL ES testsuite"
HOMEPAGE="https://android.googlesource.com/platform/external/deqp"

# This corresponds to a commit near ToT.
MY_DEQP_COMMIT='a3d4f2bdc5414efa20b0288e1bf75a4c1bd758c0'

# To uprev deqp, follow these commands:
# wget https://android.googlesource.com/platform/external/deqp/+archive/${MY_DEQP_COMMIT}.tar.gz
# gsutil cp -a public-read deqp-${MY_DEQP_COMMIT}.tar.gz gs://chromeos-localmirror/distfiles/

# When building the Vulkan CTS, dEQP requires that certain external
# dependencies be unpacked into the source tree. See ${S}/external/fetch_sources.py
# in the dEQP for the required dependencies. Upload these tarballs to the ChromeOS mirror too and
# update the manifest.
