Detailed Description

Tests the behavior of DMA on xemu's implementation of GPU-owned overlay buffers.

These tests are generally specific to emulator testing and likely should not serve as examples of how to do PGRAPH interactions, nor are they likely to illuminate unexpected behavior in HW.

Constructor & Destructor Documentation

DMACorruptionAroundSurfaceTests()

DMACorruptionAroundSurfaceTests::DMACorruptionAroundSurfaceTests	(	TestHost &	host,
		std::string	output_dir,
		const Config &	config
	)

Initializes the test suite and creates test cases.

Remarks

DMAOverlap Sets up a render target in uninitialized data and triggers a nop (degenerate triangle) draw. Then uses the guest CPU to populate the memory within the render target. Sets the render target back to the framebuffer and renders the previous surface as a texture. The texture should not exhibit any corruption from the initial state of the texture.

xemuReadFromFileIntoSurface Sets up a render target and initializes it with a dark color. Then reads new data from a file into the render target and triggers a nop (degenerate triangle) draw. Sets the render target back to the framebuffer and renders the previous surface as a texture. The texture should be bright white, the data provided in the test file.

xemuReadFromFileIntoTexture Draws a texture, then reads new data from a file over the same location in memory and draws a second time. The rendered content should change across the draws.
