Subject: [PATCH 0/3] target/s390x: Fix missing clock-comparator interrupts
Date: Tue, 14 Oct 2025 18:05:12 +0200 [thread overview]
Message-ID: <20251014160743.398093-1-iii@linux.ibm.com> (raw)
Hi,
While trying to (so far unsuccessfully) reproduce [1], I found two bugs
in the clock comparator handling. This series fixes both and adds a
test.
[1] https://lore.kernel.org/lkml/ab3131a2-c42a-47ff-bf03-e9f68ac053c0@t-8ch.de/
Best regards,
Ilya
