commit e997d055929665b12246e89eb092dc79c65de9a4 Author: Julien Grall <jgrall@xxxxxxxxxx> AuthorDate: Fri Aug 12 20:24:48 2022 +0100 Commit: Julien Grall <julien@xxxxxxx> CommitDate: Wed Aug 31 20:16:22 2022 +0100 xen/arm32: traps: Dump more information for hypervisor data abort Unlike arm64, on arm32 there are no extra information dumped (e.g. page table walk) for hypervisor data abort. For data abort, the HSR will be set properly and so call do_trap_hyp_sync() instead of do_unexpected_trap() on arm32 to have the print the same information as arm64.
