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.

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).
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.

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.

David Goldblatt
0880c2ab97
PA: Have large expands use it.

This better facilitates testing.

David Goldblatt
bf55e58e63
Rename test/unit/decay -> test/unit/arena_decay.
...
This is really more of an end-to-end test at the arena level; it's not just of
the decay code in particular any more.
2020-04-10 13:12:47 -07:00
David Goldblatt

Arena stats: mark edata_avail as derived.

The true number is in the edata_cache itself.
2020-04-10 13:12:47 -07:00
David Goldblatt
3192d6b77d
Extents: Have extent_dalloc_gap take ehooks.
...
We're almost to the point where the extent code doesn't know about arenas at
all. In that world, we shouldn't pull them out of the arena.
2020-04-10 13:12:47 -07:00
