| 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. | |
