audk/OvmfPkg/Include/IndustryStandard/Xen

The headers in this directory have been imported from the Xen Project with few

modification that are described in this README.



The modifications that needed to be done are:

- Use of ZeroMem() or SetMem() instead of memset().

- If a struct is using a 64bit field, then a #pragma(4) might be needed

  for IA32, like in io/blkif.h.

- Replace the types with the ones used in UEFI.





* Command to run to change types:

find OvmfPkg/Include/IndustryStandard/Xen -type f -name '*.h' -exec sed --regexp-extended --file=fix_type_in_xen_includes.sed --in-place {} \;



$ cat fix_type_in_xen_includes.sed

# Avoid changing the 'long' that is not a type.
