The CPU usage of the kmscube process running in DomU exceeds 50%, but its CPU usage in Dom0 does not exceed 2%.
Remark: Back-end command: displ_be -m DRM -z -v *:Debug Displ_be disables zero copy (under zero copy, the front-end error: [drm:xen_drm_drv_dumb_create [drm_xen_front]] ERROR Failed to cre ate dumb buffer: -25. Back-end error: gnttab: error: ioctl DMABUF_EXP_FROM_REFS_V2 ioctlapproate failed: Inappro device )
Thanks !
