The core magma code is found under:
Magma service drivers are found under:
Magma client drivers are third party codebases. Open source client drivers typically live in third_party/mesa.
For details on the testing strategy for magma, see Test Strategy.
There are multiple levels for magma TPS. Each level includes all previous levels.
When submitting a change, indicate the TPS level tested, prefaced by the hardware on which the testing was performed:
TEST: nuc,vim2:go/magma-tps#L2 nuc,vim2:go/magma-tps#S1 nuc,vim2:go/magma-tps#C0 nuc,vim2:go/magma-tps#P0
Includes all unit tests and integration tests. There are 2 steps at this tps level:
fx set core.x64 --with-base=//src/graphics/lib/magma/gnbuild/magma-intel-gen:magma-dev --args magma_enable_developer_build=true
--with-base //src/graphics/bundles:vulkan --with src/graphics/lib/magma/tests:l0and run the test script src/graphics/lib/magma/scripts/test.sh.
If you have an attached display, execute the spinning vkcube. This test uses an imagepipe swapchain to pass frames to the system compositor. Build with
--with-base //src/graphics/bundles:vulkan --with src/graphics/lib/magma/tests:l1. Test with present direct to display:
run fuchsia-pkg://fuchsia.com/vkcube-on-fb#meta/vkcube-on-fb.cmx --c 500 Test with present via Scenic:
ffx session add fuchsia-pkg://fuchsia.com/vkcube-on-scenic#meta/vkcube-on-scenic.cmx.
A full UI ‘smoke’ test. Build workstation, launch Chromium and navigate to a WebGL demo such as Aquarium.
Run vkcube-on-scenic overnight (12-24 hours).
A full UI stress test. Launch two instances of the spinning_cube flutter example, and let them run overnight.
For some changes, it's appropriate to run the Vulkan conformance test suite before submitting. See Conformance.
For some changes, it's appropriate to run benchmarks to validate performance metrics. See Benchmarking.
