* 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.
This makes rendering of the samples have the wrong colors on the Metal
backend, but using BGRA made end2end tests fail. The rendering color
will be fixed when the WSI is introduced.
Extract descriptor offset computation and CPU descriptor recording to
BindGroupLayout and BindGroup. Refactor descriptor heap allocation to
copy from a large CPU heap to a GPU heap.
Previously the Metal backend used a manual mutex system to make sure the
BufferSetSubData didn't have data races with reads from the GPU. Replace
this with a non-hacky version
- Make the Buffer objects allocated on the GPU
- Make SetSubData use a ResourceUploader that allocates a CPU buffer
and schedules a CPU->GPU copy.
- Have a list of pending commands and a finished command serial to
order operations and track when resource become unused.
No functional changes intended, but there are a couple additional
cleanups:
- Use anonymous namespaces instead of static functions
- Don't store an extra Device pointer in objects
Unfortunately you can't template on const-ness in C++ so we have to
duplicate all the iterator code for SerialQueue (that, or introduce very
heavy templating).
We want to test BufferMapRead validation using the null backend. To get
closer to conditions on a real backend, we call the callback only on the
next Queue::Submit. This is because on real backends, we would have to
wait for the GPU to be finished with the buffer, to be sure the correct
data is read.
