This patch set adds support for the Program-Event Recording (PER) feature. It implements all the PER functionalities except the following ones: - zero-address-detection event (part of the zero-address-detection facility) - transaction-end event (we don't implement transactional memory)
There are also a few limitations to the storage-alteration event, as it doesn't support per ASC enablement, nor it doesn't correctly provide the ASC used for a storage event in the PER AI field. With this patch set, it's possible to fully use GDB in a s390x guest, including stepping, breakpoints and watchpoints.
