Add a per-arena oversize_threshold.
...
This can let manual arenas trade off memory and CPU the way auto arenas do.

I.e. only allowing allocations under or over certain sizes.

This allows easy experimentation with them as tuning parameters.

Add PAC: Page allocator classic.
...
For now, this is just a stub containing the ecaches, with no surrounding code
changed. Eventually all the core allocator bits will be moved in, in the
subsequent stack of commits.

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).

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.

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.

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).

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.
