• xilinx_drm.fbdev_vres=2 : "fbdev virtual resolution multiplier for fb (default: 2)" This is to determine the virtual vertical resolution of the emulated fbdev buffer. The default value is 2 to enable double buffering. Higher value will allocate more memory.
• xilinx_drm_dp.aux_timeout_ms=50 : "DP aux timeout value in msec (default: 50)" This value determines the timeout for aux transaction. Some monitors (ex, in specific power state) require longer timeout, then this value can be increased. But increasing it would result in more latency in the system level response.
