Or should it be included by a c file instead? Removing it would cause a compilation breakage. It might be moved to a c file, but patch 5/10 requires it at ghes.h, as it adds this to ghes.h: void ghes_record_cper_errors(uint8_t *cper, size_t len, enum AcpiGhesNotifyType notify,Error **errp); So, instead of poking around moving this to/from .c/.h, I opted to place it on its final place. > > #include "qemu/notify.h" > > > > extern NotifierList acpi_generic_error_notifiers; > > diff --git a/qapi/acpi-hest.json b/qapi/acpi-hest.json > > Thanks, Mauro
