[PATCH][VTD] pci mmcfg patch for x86-64 - version 2
Fixes made in version 2:
1) Use PML4[257] for ioremap of PCI mmcfg. As full 16-bit segment support would require 44-bits. Since each slot only has 39-bits, we support 2048 PCI segments for now. This can be easily expanded if deemed necessary in the future.
2) Integrated PCI mmcfg access with existing PCI config interface for x86_64. Use MMCFG interface if offset is greater than 256.

doubt on phys_to_machine_mapping
...slate.
I see that, populate_physmap() after calling __alloc_xen_heap_pages only
updates the machine_to_physmap but how is the mfn for the allocated page
being updated/set for phys_to_machine_mapping??
I see that phys_to_machine_mapping is a #defined to RO_MPT_VIRT_START
which inturn is defined as PML4_ADDR(256).. what is this?? i have
completely lose track from here on.
Thanks in advance.
Regards,
Sandesh
