intel_upload_blit_large_map: microbenchmark of Intel GPU performance
NAMEintel_upload_blit_large_map - microbenchmark of Intel GPU performance
DESCRIPTIONintel_upload_blit_large_map is a microbenchmark tool for DRM performance. It should be run with kernel modesetting enabled, and may require root privilege for correct operation. It does not require X to be running.
Given that it is a microbenchmark, its utility is largely for regression testing of the kernel, and not for general conclusions on graphics performance.
