Jiaxun Yang 580724fce2 MIPS: sync-r4k: Rework based on x86 tsc_sync ... The original sync-r4k did a good job on reducing jitter by determine the "next time value", but it has a limitation that when synchronization being performed too many times due to high core count or CPU hotplug, the timewrap on CPU0 will become unaccpetable. Rework the mechanism based on latest x86 tsc_sync. (It seems like the original implementation is based on tsc_sync at that time, so it's just a refresh.) To improve overall performance. Tesed on Loongson64, Boston, QEMU. Signed-off-by: Jiaxun Yang <jiaxun.yang@flygoat.com> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>		2024-07-03 16:50:12 +02:00
