Extent: Stop passing an edata_cache everywhere.
...
We already pass the pa_shard_t around everywhere; we can just use that.

Ehooks: avoid touching arena_emap_global in tests.
...
That breaks our ability to test custom emaps in isolation.

Extent: Take "bool zero" over "bool *zero".

1a1124462e
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).

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).

Eset: Parameterize last globals accesses.

I.e. opt_retain and maps_coalesce.
2020-04-10 13:12:47 -07:00
David Goldblatt
7bb6e2dc0d
Eset: take opt_lg_max_active_fit as a parameter.
...
This breaks its dependence on the global.

Edata: Add a ranged bit.

We steal the dumpable bit, which we ended up not needing.

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

Stats: Fix edata_cache size merging.

Previously, we assigned to the output rather than incrementing it.

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.

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

PA: Move edata_avail stat in, make it non-atomic.

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).

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: have expand take sizes instead of new usize.
...
This avoids involving usize, which makes some of the stats modifications more
intuitively correct.
2020-04-10 13:12:47 -07:00
David Goldblatt
5bcc2c2ab9
PA: Have expand take szind and slab.
...
This isn't really necessary, but having a uniform API will help us later.
2020-04-10 13:12:47 -07:00

PA: Have large expands use it.

This better facilitates testing.
