Dmitry Ilvokhin aaa29003ab Limit maximum number of purged slabs with option ... Option `experimental_hpa_max_purge_nhp` introduced for backward compatibility reasons: to make it possible to have behaviour similar to buggy `hpa_strict_min_purge_interval` implementation. When `experimental_hpa_max_purge_nhp` is set to -1, there is no limit to number of slabs we'll purge on each iteration. Otherwise, we'll purge no more than `experimental_hpa_max_purge_nhp` hugepages (slabs). This in turn means we might not purge enough dirty pages to satisfy `hpa_dirty_mult` requirement. Combination of `hpa_dirty_mult`, `experimental_hpa_max_purge_nhp` and `hpa_strict_min_purge_interval` options allows us to have steady rate of pages returned back to the system. This provides a strickier latency guarantees as number of `madvise` calls is bounded (and hence number of TLB shootdowns is limited) in exchange to weaker memory usage guarantees.		2024-08-20 10:02:38 -07:00
