When the gpfifo data in the gpu_va buffers specified by the submitted gpfifo entries is invalid(?), eventually the user-process will be force-terminated after using the submit-gpfifo ioctl. It's unknown how exactly this is done.

GPU rendering (GPFIFO) is only used by applets/Applications. All sysmodules doing any gfx-display uses software rendering. During system-boot, GPU GPFIFO is not used until the applets are launched.
