* [vulkan] Vulkan API auto-selection for latest available.
- Selects for the maximum vulkan API version available on the host's vulkan driver for a created instance.
- Stores the created instance's vulkan API version on RendererContextVK.
- Created instance's vulkan API version dumped using BX_TRACE in MAJOR.MINOR.PATCH format.
- Physical Device's vulkan API version dumped in MAJOR.MINOR.PATCH format.
* Address code review notes.
- Actually use `vkEnumerateInstanceVersion` if it exists.
- Remove "bgfx supported" vulkan api static array.
* 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.
* WGL support for passing a context when using renderFrame on non main thread
* NSGL support for passing a context when using renderFrame on non main thread
* WGL: Moved no window warning and added check prior to calling GetDC
When resizing the window, there's a race condition between the
validation of vkCreateSwapchainKHR's arguments and the actual
size of the window.
This ignores the validation warning when vkCreateSwapchainKHR succeeds.
On some graphic drivers vkAcquireNextImage and vkQueuePresentKHR
may return VK_SUBOPTIMAL_KHR. This is being handled as an error, which
leads to those frames being unnecessarily skipped.
