## TCMalloc extension API
extension = []
## Enable NUMA-aware allocation. Need to use `TCMALLOC_NUMA_AWARE` environment variable at runtime.
## See [TCMalloc comments](https://github.com/google/tcmalloc/blob/master/tcmalloc/internal/numa.cc#L54)
numa_aware = []
## Use deprecated per-thread caching. Newer systems with Linux kernel version >= 4.18 should not use this.
deprecated_perthread = []
## Use legacy locking. See [TCMalloc docs](https://github.com/google/tcmalloc/blob/master/docs/design.md#tcmalloc-backend)
legacy_locking = []

#! ### Logical Page Sizes (These features are mutually exclusive).
#! Larger page size leads to greater performance in expense to increased fragmentation.
#! See [TCMalloc tuning guide](https://github.com/google/tcmalloc/blob/master/docs/tuning.md#the-logical-page-size-for-tcmalloc)

## 8k pages
8k_pages = []
## Large pages
32k_pages = []
## 256k pages
256k_pages = []
## 4k pages, option for memory-constrained systems
small_but_slow = []

#! ### Madvise Transparent Hugepages control (Use no more than one value)
#! By default, if none of these features are enabled, madvise hugepages will be enabled.

## Disable madvise hugepages
disable_madv_hugepage_always = []
## Disable madvise hugepages via environment variable `TCMALLOC_DISABLE_MADV_HUGEPAGE` at runtime.
## This variable can be set to `0` or `1` to enable or disable madvise hugepages respectively.
