Create command lists for a resource transitioning to/from app control.

Parameters

	device	D3D12 device
	command_allocator
	resource	image
	bits	Swapchain usage bits
[out]	out_acquire_command_list	Command list to populate for xrAcquireSwapchainImage
[out]	out_release_command_list	Command list to populate for xrReleaseSwapchainImage

Returns

HRESULT

Todo:

do we need to set queue access somehow?

Todo:

No idea if this is right, might depend on whether it's the compute or graphics compositor!

createDevice()

wil::com_ptr< ID3D12Device > xrt::auxiliary::d3d::d3d12::createDevice	(	const wil::com_ptr< IDXGIAdapter > &	adapter = nullptr,
		u_logging_level	log_level = U_LOGGING_INFO
	)

Create a D3D12 Device object.

Parameters

adapter	optional: adapter to create on.
log_level	The level to compare against for internal log messages

Exceptions

wil::ResultException

in case of error

Returns

wil::com_ptr<ID3D12Device>

importFence()

wil::com_ptr< ID3D12Fence1 > xrt::auxiliary::d3d::d3d12::importFence	(	ID3D12Device &	device,
		HANDLE	h
	)

Imports a fence into D3D12 from a handle.

Parameters

device	D3D12 device
h	handle corresponding to a shared fence

Exceptions

std::logic_error

if the handle is invalid, wil exceptions if the operation failed.
