Colour only, depth/stencil copy not supported.
This means that we only report pre-mod and post-mod colour values for
events. Since stencil copy is not supported, number of fragments is
not reported, and shader output is not queried.
Also:
- support for choosing mip level and slice
- tests for secondary command buffers
- adds a callback around vkCmdExecuteCommands
- refactors pixel history occlusion callback into its own
callback. Allows processing fewer events later on, and getting colour
information separately.
- keep track of subpassContents for vkCmdBeginRenderPass (inline or
secondary)
+ a small pixel history fix for figuring out if depth test failed
- the test demo is based on overlay demo, with a few modifications so
far: added a draw that will fail on culling, added shader discard for
any pixel with x = 150
- tests some basic failed tests: stencil, depth, culling, shader discard
* This is a very big blunt hammer for fixing the problem of multithreaded
submission from GL. Every GL call checks to see if the context changed (which
would only happen from a thread switch to a different context) and if detected
it inserts a manual MakeCurrent call equivalent.
* It's slow to capture (when this happens - checking is not particularly slow)
and slow to replay, but it's functional which is an improvement.
* This allows persistent config storage and registering tweak variables that
works independent of the UI's configuration.
* Config vars can be debug only, which means they will be compiled out in stable
version releases. This allows for debug-logging tweaks that are available in
all builds (including nightly builds) for diagnostic purposes, but have zero
overhead in stable releases.
* Variables have a loose hierarchy defined with _ or . to separate nodes.
When getting read only resources from the pipe state, stitch back up
according to the bindpoint mappings. When displaying resources in UI,
don't traverse unbounded arrays. Fix resource swizzle on load/sample/
gather instructions, which happens on fetch result, not on the source
operand. Added more tests for unbounded arrays and different ways to
index into arrays.
The assignment of logical identifiers is not guaranteed to match the
order of appearance in the shader bytecode. Adjusted D3D12_CBuffer_Zoo
to exercise this for testing.
* This doesn't test every edge case, but it is a simple smoke test that ensures
any format can at least get consistent accurate results out.
* Further work is needed to test the different failures, overdraws, primitive
IDs, and all the other specific checks in the history.
* The builtin is more directly useful but the signature index allows us to match
up inputs and outputs that don't have a builtin meaning (pure interpolators).
SV_PrimitiveID is only valid as a pixel shader input if there's either
no geometry shader, or the geometry shader emits SV_PrimitiveID. With
D3D11, the debug layer will complain but rendering will proceed. With
D3D12, the PSO fails to compile. For both APIs, pixel shader debugging
now checks whether this is true, and disables its usage if it isn't.
Added tests for various valid scenarios with SV_PrimitiveID.
* It's not particularly scalable and can be brittle to driver changes, and we
can use targeted specific pixel tests to check what we really want - to see if
the output has rendered correctly.
* Overlay tests still check files directly - this is a future refactor to
remove.
