[PATCH 0/7] MIPS: clocksource cumulative enhancements
From: Jiaxun Yang
Date: Sat May 11 2024 - 12:00:21 EST
Hi all,
This series combined many enhancements for MIPS clocksource subsystems,
It improved r4k count synchronisation process, clock source rating for
selection, sched_clock eligibility and so on.
It seems fixed random RCU stall issue on Loongson 3A4000 multi-node
system and some boot failures on QEMU.
Please review.
Thanks
