A large buffer is allocated and solid color clear operations are executed on it with randomly chosen properties (position and size of the region, clear color). Execution time is measured and output together with the amount of pixels processed. The 'simple' variant only executes one G2D command buffer at a time, while the 'multi' variant executes multiple ones. This can be used to measure setup/exec overhead. The test also serves a stability check. If clocks/voltages are too high or low respectively, the test quickly reveals this. v2: Add GPLv2 header, argument handling and documentation. Tool is only installed when requested. v3: Free images array in fimg2d_perf_multi() as pointed out by Hyungwon Hwang. v4: Include header for error numbers (fixes build). v5: Add binary to .gitignore.
