sys/dev/pv : viogpu.c
Log message:
viogpu_wsmmap() returns a kva but instead should return a physical
address via bus_dmamem_mmap(9). Without this, QEMU would only show a
black screen when starting X11. On the Apple Hypervisor, the kernel
would panic.
Also add calls to bus_dmamap_sync(9) before transferring the framebuffer
to host memory. It was working for me without this, but this ensures
that the host running on another CPU will see updates to the
framebuffer.
Thanks to kettenis@ for reviewing and providing feedback.
