* 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
* 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.
1. A crash in D3D11 renderer when create a texture with flag BGFX_TEXTURE_RT_WRITE_ONLY then override it, bcause m_srv is NULL.
2. In headless mode, RendererContextD3D12::m_swapChain is NULL, clear it resulting a D3D12 debug error
