commit dd24d475d514bba755111c5eecfef1d362b9d68c Author: Mark Johnston <[email protected]> AuthorDate: 2023-07-28 13:32:45 +0000 Commit: Mark Johnston <[email protected]> CommitDate: 2023-07-28 13:34:38 +0000 arm64: Add constants for decoding ISS fields for WF* exceptions WFI and WFIT trap to EL2 when executed in a vmm guest. (Currently WFE/WFET are not configured to trap.) We only handle WFI at the moment, so these constants are useful when handling the exception.
