Member Function Documentation

GetCompletedValue()

xiiUInt64 xiiGALFenceD3D12::GetCompletedValue ( )

finaloverridevirtual

This returns the last completed value signaled by the GPU.

Remarks

In Direct3D11 backend, this method is not thread-safe (even if the fence object is protected by a mutex) and must only be called by the same thread that signals the fence via an enqueue.

Implements xiiGALFence.

InitPlatform()

xiiResult xiiGALFenceD3D12::InitPlatform ( )

finaloverrideprotectedvirtual

Implements xiiGALFence.

SetDebugNamePlatform()

void xiiGALFenceD3D12::SetDebugNamePlatform ( xiiStringView sName ) const

finaloverrideprotectedvirtual

Reimplemented from xiiGALObject.

Signal()

void xiiGALFenceD3D12::Signal ( xiiUInt64 uiValue )

finaloverridevirtual

This sets the fence to the specified value.

Parameters

uiValue

- The new value the fence should reach. The value must be greater than the current value of the fence.

Note

Fence value will be changed immediately on the CPU. Use device to enqueue a signal command that will change the value on the GPU after all previously submitted commands are complete.

The fence must have been created with type General.

Implements xiiGALFence.

Wait()

void xiiGALFenceD3D12::Wait ( xiiUInt64 uiValue )

finaloverridevirtual

This waits until the fence reaches or exceeds the specified value on the host.

Parameters

uiValue

- The value that the fence is waiting to reach.

Note

The method blocks the execution of the calling thread until the wait is complete.

Implements xiiGALFence.
