lv1_gpu_context_attribute:fb_blit (225)

Block Image Transfer from Main memory to GPU memory.

This is a specific operation of the generic operation lv1_gpu_context_attribute(...);

Kernel Call

status = lv1_gpu_context_attribute(ps3fb.context_handle,
			           L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT,
				   offset, fb_ioif,
				   L1GPU_FB_BLIT_WAIT_FOR_COMPLETION |
				   (xres << 16) | yres,
				   xres * BPP);

Parameters

Inputs
Register	Description
R3	ps3fb.context_handle as allocated by lv1_gpu_context_allocate theoretically.
R4	operation_code - L1GPU_CONTEXT_ATTRIBUTE_FB_BLIT (0×601)
R5	destination GPU address (offset in video RAM).
R6	source GPU address (GPU_IOIF + offset, for system RAM mapped by lv1_gpu_context_iomap).
R7	0×0000 : 0×0000 : xres : yres - x,y size of the blit.
R8	line_length - span, number of bytes in a line. As of Firmware 1.90, lower 32-bit is destination span, upper 32-bit if not null is source span.
Outputs
Register	Description
R3	Status - 0 = OK, Other values are unknown, but indicate failure.
