Tcache: treat small and large cache bins uniformly
2020-04-14 15:20:19 -07:00

Tcache: split up fast and slow path data.
2020-04-14 15:20:19 -07:00

Arena: fill in terms of cache_bins.
2020-04-14 15:20:19 -07:00

PA: Take zero as a bool rather than as a bool *.
...
Now that we've moved junking to a higher level of the allocation stack, we don't
care about this performance optimization (which only occurred in debug modes).
2020-04-10 13:12:47 -07:00
294b276fc7
PA: Parameterize emap. Move emap_global to arena.
...
This lets us test the PA module without interfering with the global emap used by
the real allocator (the one not under test).

Emap: Move edata modification out of emap_remap.

Arena stats: Give it its own "mapped".
...
This distinguishes it from the PA mapped stat, which is now named "pa_mapped" to
avoid confusion. The (derived) arena stat includes base memory, and the PA stat
is no longer partially derived.
2020-04-10 13:12:47 -07:00
506d907e40
PA: Move in basic stats merging.
2020-04-10 13:12:47 -07:00

PA: Add pa_extra.c and put PA forking there.
2020-04-10 13:12:47 -07:00

Stats: Fix edata_cache size merging.
...
Previously, we assigned to the output rather than incrementing it.

Arena: Make more derived stats non-atomic/locked.
2020-04-10 13:12:47 -07:00
d0c43217b5
Arena stats: Move retained to PA, use plain ints.
...
Retained is a property of the allocated pages. The derived fields no longer
require any locking; they're computed on demand.
2020-04-10 13:12:47 -07:00

PA: Move in all modifications of mapped.
2020-04-10 13:12:47 -07:00
436789ad96
PA: Make mapped stat atomic.
...
We always have atomic_zu_t, and mapped/unmapped transitions are always expensive
enough that trying to piggyback on a lock is a waste of time.
2020-04-10 13:12:47 -07:00
3c28aa6f17
PA: Move edata_avail stat in, make it non-atomic.
2020-04-10 13:12:47 -07:00
f6bfa3dcca
Move extent stats to the PA module.
...
While we're at it, make them non-atomic -- they are purely derived statistics
(and in fact aren't even in the arena_t or pa_shard_t).
2020-04-10 13:12:47 -07:00

PA: Move in nactive counter.

PA: Move in stash_decayed.
2020-04-10 13:12:47 -07:00

Move bg inactivity check out of purge inner loop.
...
I.e. do it once per call to arena_decay_stashed instead of once per muzzy purge.
2020-04-10 13:12:47 -07:00

PA: Move in remaining page allocation functions.
2020-04-10 13:12:47 -07:00

PA: Have slab allocations use it.
2020-04-10 13:12:47 -07:00

PA: Move in arena large allocation functionality.
2020-04-10 13:12:47 -07:00

Remove extent knowledge of arena.
2020-04-10 13:12:47 -07:00

Move arena decay getters to PA.
2020-04-10 13:12:47 -07:00

Decay: Take current time as an argument.
...
This better facilitates testing.
2020-04-10 13:12:47 -07:00

Decay: Move in arena decay functions.
2020-04-10 13:12:47 -07:00

Introduce decay module and put decay objects in PA
2020-04-10 13:12:47 -07:00

PA: Move mapped into pa stats.
2020-04-10 13:12:47 -07:00

PA: Move in arena extent_sn counter.
...
Just another step towards making PA self-contained.
2020-04-10 13:12:47 -07:00
1ad368c8b7
PA: Move in decay stats.
2020-04-10 13:12:47 -07:00
356aaa7dc6
Introduce lockedint module.
...
This pulls out the various abstractions where some stats counter is sometimes an
atomic, sometimes a plain variable, sometimes always protected by a lock,
sometimes protected by reads but not writes, etc. With this change, these cases
are treated consistently, and access patterns tagged.
In the process, we fix a few missed-update bugs (where one caller assumes
"protected-by-a-lock" semantics and another does not).
2020-04-10 13:12:47 -07:00

PA: move in ecache_grow.
2020-04-10 13:12:47 -07:00

PA: Add a stats type.
2020-04-10 13:12:47 -07:00

PA: Move in the arena edata_cache.
2020-04-10 13:12:47 -07:00

PA: move in shard initialization.
2020-04-10 13:12:47 -07:00

PA: Move in the ecache_t objects.
2020-04-10 13:12:47 -07:00
585f925055
Move cache index randomization out of extent.
...
This is logically at a higher level of the stack; extent should just allocate
things at the page-level; it shouldn't care exactly why the callers wants a
given number of pages.
2020-04-10 13:12:47 -07:00

Stats: Fix tcache_bytes reporting.
...
Previously, large allocations in tcaches would have their sizes reduced during
stats estimation. Added a test, which fails before this change but passes now.
This fixes a bug introduced in 59348466129c0549007d
