For example: 1) USB based display adapter, such as FL2000DX[1] which use the it66121 HDMI transmitter to convert the RGB888 to HDMI. 2) Simple 2D PCIe display controller, such as SM750(EMPV-1201) which using sii9022 HDMI transmitter to convert the RGB888 to HDMI. 3) Some FPGA PCIe Board (sil9136) 4) Be able to run unit test of drm bridges on X86.
