hpdata: Add a test.
...
We're about to make the functionality here more complicated; testing hpdata
directly (rather than relying on user's tests) will make debugging easier.

Introduce hpdata_t.
...
Using an edata_t both for hugepages and the allocations within those hugepages
was convenient at first, but has outlived its usefulness. Representing
hugepages explicitly, with their own data structure, will make future
development easier.

Add fxp: A fixed-point math library.

This will be used in the next commit to allow non-integer values for
narenas_ratio.

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

Rename geom_grow -> exp_grow.
...
This was promised in the review of the introduction of geom_grow, but would have
been painful to do there because of the series that introduced it. Now that
those are comitted, renaming is easier.

Allow opt.tcache_max to accept small size classes.
...
Previously all the small size classes were cached. However this has downsides
-- particularly when page size is greater than 4K (e.g. iOS), which will result
in much higher SMALL_MAXCLASS.
This change allows tcache_max to be set to lower values, to better control
resources taken by tcache.

Add SEC module: a small extent cache.
...
This can be used to take pressure off a more centralized, worse-sharded
allocator without requiring a full break of the arena abstraction.

Add hpa_central module
...
This will be the centralized component of the coming hugepage allocator; the
source of larger chunks of memory from which smaller ones can be obtained.
2020-10-05 19:55:57 -07:00

Add psset: a set of pageslabs.
...
This introduces a new sort of edata_t; a pageslab, and a set to manage them.
This is part of a series of a commits to implement a hugepage allocator; the
pageset will be per-arena, and track small page allocations requests within a
larger extent allocated from a centralized hugepage allocator.

Rename ecache_grow -> geom_grow.

We're about to start using it outside of the ecaches, in the HPA central
allocator.

Add sized-delete size-checking functionality.
...
The existing checks are good at finding such issues (on tcache flush), but not
so good at pinpointing them. Debug mode can find them, but sometimes debug mode
slows down a program so much that hard-to-hit bugs can take a long time to
crash.
This commit adds functionality to keep programs mostly on their fast paths,
while also checking every sized delete argument they get.

The flat_bitmap module offers an extended API, at the cost of decreased
performance in the case of very large bitmaps.

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.

Cache_bin: Shouldn't know about tcache.

Instead, have it take the cache_bin_info_ts to use by pointer. While we're
here, add a src file for the cache bin.

Implement opt.stats_interval and the _opts options.
...
Add options stats_interval and stats_interval_opts to allow interval based stats
printing. This provides an easy way to collect stats without code changes,
because opt.stats_print may not work (some binaries never exit).

...
Eventually, we may fully break off the extent module; but not for some time. If
it's going to live on in a non-transitory state, it might as well have the nicer
name.
