There was a lot of missing around with viewports and flip the Y
coordinate in vertex shaders before. Turns out things are simpler than
we thought: *all* APIs have gl_Position(-1, -1) map to texel (0, 0). It
is just the present coordinate system that changes.
Remove some of the hacks we had to work around non-existent viewport
issues and fix tests.
Sometimes NXT provides default objects for parts of the pipelines, for
example a default pipeline layout. This objects were create with code
like: device->CreateFooBuilder()->GetResult(); and stored in a Ref<>.
This caused the object to have on external reference and two internal
references and not get destroyed when the Ref<> goes out. Call Release
on these objects to remove the external reference and fix the leak.
Was found via the Vulkan validation layers that were complaining that a
VkPipelineLayout was leaked.
This as this is the first command handled by the Vulkan backend, this
commit also introduces the b:✌️:CommandBUffer class and implements
b:✌️:Queue::Submit.
Also enables the BufferSetSubData tests that are now passing on Vulkan
even though the buffer transitions are unimplemented.
This introduce a new FencedDeleter service as part of the Device
objects that tracks when resources are no longer used and deletes them.
BufferVk takes advantage of this to defer the deletion of its handle
that was previously incorrectly delete directly in ~BufferVk.
On 32 bit Vulkan typedefs these handles to uint64_t which breaks
function overload resolution. Replace the
VK_DEFINE_NON_DISPATCHABLE_HANDLE and VK_NULL_HANDLE defines to be
opaque C++ types with the same capabilities.
Previously we would modify the GL state as soon as we saw
SetIndex/VertexBuffers. This GL state is owned by the VAOs in the
InputState and was disappearing on a Pipeline change. Fix this by
applying the index / vertex buffers lazily.
This was because the clip space of OpenGL has an inverted Y compared to
other APIs. This commit:
- Updates SPIRV-Cross to the latest version
- Uses the new vertex.flip_vert_y option in ShaderModuleGL
- Enables tests that are now passing in GL.
Explicitly configure swap chain usage in bindings and examples
Fix missing case in switch
Make swap chain Present usage implicit
Author: Austin Eng <enga@google.com>
This is to avoid a potential future problem if SetPipelineCommon were to
ever return false (which is currently not possible), some state might
have been modified incorrectly.
Previously didn't tell SPIRV-Cross at which MSL resource indices the
different SPIRV binding should be, and were lucky that it's giving
indices in increasing order matched the PipelineLayout in all our
samples.
Fix this by making SPIRV->MSL compilation depend on the PipelineLayout
so we can tell SPIRV-Cross which binding goes where.
We should do the same for vertex attributes eventually as they are
hardcoded to start at kMaxBindingsPerGroup currently.
Also a couple unrelated cleanups (unused function, usage of
IterateBitSet).
* clang/gcc: enable -pedantic warnings
* suppress a GCC-specific warning in stb_image
* And some clang-specific warnings
* -Wconversion (clang) -Wold-style-cast (clang+gcc)
and fix a few warnings that show up with these (and a few more with
-Wconversion on gcc, even though that's not enabled by default)
* bunch more warnings
* fixes
* remove merge error
Adds the swap chain interfaces to the API without changing the behavior
of anything else. This includes the C APIs for applications to provide
swap chain implementations. Also adds stub implementations on every
backend.
Implements BeginRenderSubpass on the D3D12 backend. Descriptors for render target and depth stencil views are recorded in a descriptor heap for each framebuffer. For now, we still have the hack where no attachment renders to the backbuffer, so the CommandBuffer records those when necessary when it is submitted.
This PR also enables input states for D3D12 which are mostly working. One failure seems to be happening because our texture copies are not yet correct.
Probably not the most efficient implementation, but works.
Issues:
* Doesn't seem to render until the second frame. No clue why, yet.
* Hardcoded 640x480 in more places.
* Creates new FBOs for every subpass every frame. Should be done at Framebuffer build or CommandBuffer build time.
This macro has some advantages over the standard library one:
- It prints the place where the macro was triggered
- It "references" the condition even in Release to avoid warnings
- In release, if possible, it gives compiler hints
It is basically is stripped down version of the ASSERT macros I wrote
for the Daemon engine in src/common/Assert.h
This commit also removes the stray "backend" namespaces for common/
code.
This directory used to contain both the state tracking code for the
backends, and the common utilities that could be used both by the
backends and the rest of the code. Things are now:
- src/common is utility code for the whole repo
- src/backend contains libNXT's code
- src/utils is utility code that we don't want in libNXT
This commit also changes all includes to use global paths from src/
bacause it had to touch a bunch of #include statements anyway.
Buffers with MapRead allowed are created on the READBACK heap and always
add the D3D12_RESOURCE_STATE_COPY_DEST state (required by D3D12).
Likewise MapWrite adds the D3D12_RESOURCE_STATE_GENERIC_READ state and
places resources on the UPLOAD heap. Because these states are
required, transitions for mapped buffers do nothing.
