This also adds a little helper to fuzz that allows us to see what GPU is being targeted. This is the first step in getting a SwiftShader fuzz target. To prove that this works, simply download this patch and run: ./docker/skia-with-swift-shader-base/build-with-swift-shader-and-run "out/with-swift-shader/fuzz --gpuInfo -t api -n NativeGLCanvas -b out/with-swift-shader/fiddle" Running supplied command ['out/with-swift-shader/fuzz', '--gpuInfo', '-t', 'api', '-n', 'NativeGLCanvas', '-b', 'out/with-swift-shader/fiddle'] Fuzzing NativeGLCanvas...

# This script compiles and runs a skia app using Swiftshader in a docker container, making it easy
|
|
# to use Swiftshade w/o having to over-write /usr/local/lib/libEGL.so and related on the
|
|
# host development machine.
|
|
|
|
# The Skia repo to be compiled will be the one on the host machine, which will
|
|
# default to the one specified by the environment variable $SKIA_ROOT with a fallback to the
|
|
# current working directory.
|
|
|
|
# Example usage
|
|
|
|
# Prove SwiftShader is really being used:
|
|
# build-with-swift-shader-and-run "out/with-swift-shader/fuzz --gpuInfo -t api -n NativeGLCanvas"
|
|
|
|
# Notice the output says GL_RENDERER Google SwiftShader
|
|
# After running the above, feel free to check out $SKIA_OUT/out/with-swift-shader. It has binaries
|
|
# but if you try to run out/with-swift-shader/fuzz --gpuInfo -t api -n NativeGLCanvas w/o using
|
|
# Docker, it will use the host's GPU (e.g. GL_VENDOR NVIDIA Corporation).
|
|
|
|
# Reproduce a fuzzer bug in SwiftShader:
|
|
# First, copy the test case into $SKIA_ROOT, say $SKIA_ROOT/skbug_1234
|
|
# build-with-swift-shader-and-run "out/with-swift-shader/fuzz -t filter_fuzz -b /skia/skbug_1234"
|
|
|
|
# $SKIA_ROOT gets mapped to /skia - other than that, the docker container does not have
|
|
# access to the host file system.
