开发板的glsdk7.0，在编译qt后通过调用qtopengl方法调用开发板的显示出错如下：
gbmpvr: ERROR: is_ptr:58: mincore failed PVR:(Warning): LoadWSModule: Window system module libpvrws_KMS.so did not validate native display [98, /generic_ws.c] wlpvr: ERROR: is_ptr:155: mincore failed PVR:(Warning): LoadWSModule: Window system module libpvrws_WAYLAND.so did not validate native display [98, /generic_ws.c] kmscube works, but it does drm and gbm initilisation before EGL. Moving the EGL stuff so it happens before drm and gbm causes the same issue.
但是开发板自带的daemo,如kmscub均可以使用。
qt版本尝试过4.8以及高版本（5.5）调用eglfs均出错
