Subject: [PATCH 0/2] target/s390x: Implement Early Exception Recognition
Date: Tue, 14 Mar 2023 12:00:20 +0100 [thread overview]
Message-ID: <20230314110022.184717-1-iii@linux.ibm.com> (raw)
Hi,
Currently loading bad PSW flags does not lead to an exception, which is
not correct. This series fixes this by implementing what PoP calls
"Early Exception Recognition". Since it applies to both loading PSW with
LPSW/LPSWE and to interrupt handling, s390_cpu_set_psw() looks like the
right place for it to be in.
Patch 1 fixes the issue, patch 2 adds a test.
Best regards,
Ilya
