Subject: [PATCH clocksource v2 0/7] Clocksource watchdog updates for v6.3
Date: Tue, 24 Jan 2023 16:27:08 -0800 [thread overview]
Message-ID: <20230125002708.GA1471122@paulmck-ThinkPad-P17-Gen-1> (raw)
Hello!
This series contains clocksource-watchdog updates:
1. Print clocksource name when clocksource is tested unstable,
courtesy of Yunying Sun.
2. Loosen clocksource watchdog constraints.
3. Improve read-back-delay message.
4. Improve "skew is too large" messages.
5. Suspend the watchdog temporarily when high read latency detected,
courtesy of Feng Tang.
6. Verify HPET and PMTMR when TSC unverified.
7. x86/tsc: Add option to force frequency recalibration with HW
timer, courtesy of Feng Tang.
Changes since v1:
o Add system descriptions to #5 and #6 in response to questions
from Thomas Gleixner.
o Add patch #7.
Thanx, Paul
