* Add 'frameNumber' to Frame struct
Previously, the frame number returned from bgfx::frame() was tracked separately in the Context. Now,
we store that information in the Frame. This will allow us to attach the frame number to ViewStats.
* Add frame number to ViewStats
When ViewStats are enabled, we tag each timer query with the current frame number, then include
that information in the final results. In this way, clients can correlate specific work that they
submitted to specific GPU timing information.
NOTE: Some backends not implemented, yet. They will always have 0 for frame number.
The ones which are implemented are:
* OpenGL
* Vulkan
* D3D 9,11,12
* Noop
d3d9: Do software conversion to take advantage of B5G6R5.
d3d11: Do software conversion to take advantage of B5G6R5.
gl: Set internal representation to swap R and B.
metal: Swizzle R and B and remove software conversion.
* texture format info: Invert R and B in RGBA4
d3d9: Revert 06c08adc9e to force software
conversion because the format doesn't exist
d3d11: Force software conversion because the format doesn't exist
gl: Revert 3e3e655262 to swizzle R and B
mtl: Swizzle channels
* metal: Remove explicit conversion of RGBA4 and RGB5A1 in osx
* metal: Set alpha bit to correct end of short
d3d9: Revert 76db2ed38d to force software
conversion and use the format that does exist
d3d11: Force software conversion because the format doesn't exist
gl: Revert b36aa71403 to swizzle R and B
mtl: Swizzle R and B
* D3D12: Fix ResolveSubresource texture format parameter
For depth textures this always returned the TYPELESS one, but instead it should have passed the FLOAT.
* D3D11: Fix ResolveSubresource texture format parameter
For depth textures this always returned the TYPELESS one, but instead it should have passed the FLOAT.
* WebGPU: Add texture format (shaderc bin version 10)
* WebGPU: Simplify storage images + Fix format decorations
* Shaderc: Cleanup Texture name assumption in textures
* Vulkan: calculate vertex count from all streams, not just the first
...which might not exist in the first place
* Vulkan: use correct vertex stream offsets and handles
* D3D11: remember stream vertex count when no index buffer is bound
* Fix out of bounds index for unknown device types
* Vulkan: Insert barrier before image host reads
* Vulkan: Make commands wait for the wait semaphore
Making commands wait at BOTTOM_OF_PIPE is a no-op, resulting in instant execution
* Vulkan: Insert barrier between views/dispatches instead of waiting on the host
* Vulkan: Fix determination of access flag from image layout
This fixes two write-after-write races with copy commands after a layout transition to VK_IMAGE_LAYOUT_TRANSFER_SRC_OPTIMAL
* Add BGFX_MAX_FRAME_LATENCY define
Affected backends either used a magic value of 3 or defined their own XX_MAX_FRAMES_IN_FLIGHT to be 3
* Vulkan: Include indirect draw in pipeline barrier
* Vulkan: honor init.resolution.numBackBuffers for swapchain size
* Make max frame latency configurable at compile time
* D3D12: Fix readback for non-zero mip
* Fix blit with non-zero mip
This required clamping the blit extents to the mip size, which is moved out of the renderers now
* Assert formatting
* Adds UAV support for D3D12, Vulkan and reworked support for OpenGL, D3D11
UAV support is now uniform across compute and draw.
To set a UAV you just use bgfx::setImage() and IMAGE2D in the shader, just like in compute.
Due to these changes shaders will have to be recompiled.
The changes include:
- D3D11 requires patching of the UAV slot number (which is now done by modifying the DXBC instead of using a macro)
- If the DXBC binary includes a debug chunk, that is also patched to match the new slot number
- All the other renderers don't need any kind of patching
- There are some shader annotations to better convert the UAV format used in hlsl to spirv
Possibility of further enhancements:
- bgfx::setViewFrameBuffer() only supports binding to a framebuffer or, using BGFX_INVALID_HANDLE, to bind the default backbuffer. This doesn't allow for the case where there is no need to bind to either one of them, for example when using a fragment shader only to read and write to an UAV.
* Bump shader version, because they need to be recompiled.
