Hi,

has anyone used the dmover(9) kernel interface to create a way to do 
PCI bus transfers more quickly using the bus_dma abstractions?  Looking 
through the code in 3.1 I don't see anything for the x86 architecture.  
I'd like to use dmover for a large framebuffer in my new NetBSD window 
system.  It seems like a good abstraction, and I'd rather not have to 
reinvent the X11 code for PCI transfers.  At the moment I'm using some 
SSE assembly in the nx_vbe_driver program, and ideally I'd like to use 
dmoverio, if possible.  I'm also going to write other video drivers 
(very slowly) based on the existing X11 drivers, and dmover would 
probably be useful for those as well.

By the way, my window system is here:

I have a little internals document here:

Thanks,
