Detailed Description

A Xenos GPU. It adds what the guest kernel needs beyond presenting. GraphicsSystem routes the kernel's calls here only when the title requires the Xenos family.

Member Function Documentation

AsXenos()

IXenosGraphicsDriver * rex::gpu::IXenosGraphicsDriver::AsXenos ( )

inlinefinalvirtual

Casts to the Xenos driver. Works across a module boundary where dynamic_cast does not.

Returns

The Xenos driver, or nullptr for a native driver.

Reimplemented from rex::gpu::IGraphicsDriver.

EnableReadPointerWriteBack()

virtual void rex::gpu::IXenosGraphicsDriver::EnableReadPointerWriteBack ( u32 address, u32 block_size_log2 )

pure virtual

Writes the ring's read pointer to guest memory as commands complete. Guest thread.

Parameters

address	Guest physical address to write it to.
block_size_log2	Log2 of the quadwords between writes.

InitializeRingBuffer()

virtual void rex::gpu::IXenosGraphicsDriver::InitializeRingBuffer ( u32 address, u32 size_log2 )

pure virtual

Starts reading commands from the guest ring buffer. Guest thread.

Parameters

size_log2

Log2 of its size in quadwords.

ReadRegister()

virtual u32 rex::gpu::IXenosGraphicsDriver::ReadRegister ( u32 index )

pure virtual

Reads a GPU register for the guest. Any guest thread.

WriteRegister()

virtual void rex::gpu::IXenosGraphicsDriver::WriteRegister ( u32 index, u32 value )

pure virtual

Writes a GPU register for the guest. Any guest thread.
