Physical address mapping to user space in dom0 problem
...I/O and DMA
buffer. If I use io_remap_pfn_range instead of remap_pfn_range, I/O
mapping works but DMA buffer mapping return -1.
Is this a known problem for XEN 3.0.4 and will be fixed later? Is there any
alternative way to map the DMA address to user space in XEN dom0?
Thanks in advance,
hyang
