Is that using drm at all? As per my post a while back, I'm still
chipping away at trying to get the bochs_drm framebuffer fired up in
QEMU's sun4u.

So far I've managed to figure out that I need to add Simba support to
QEMU which is taking longer than expected as various OSs make
assumptions about the interrupt-swizzling for Ultra 5 on-board devices.

However outside of the interrupt issues, I now have something that
seemingly boots a kernel built from source and initialises the IOMMU
correctly. Now all I need to do now is figure out why the DRM memory
mapping routines never map the framebuffer to a virtual address and
always fallback to returning the physical address...


ATB,
