// tiny_mem_stats_box.h - Lightweight memory accounting for Tiny front boxes
|
||
|
|
//
|
||
|
|
// Purpose:
|
||
|
|
// - Provide coarse-grained byte counters for major Tiny front allocations
|
||
|
|
// (Unified Cache buffers, Warm Pool TLS state, Page Box TLS state,
|
||
|
|
// TLS magazine/front caches, and policy/stats tables).
|
||
|
|
// - Keep overhead near-zero: helpers are simple fetch-adds, typically called
|
||
|
|
// at init time when the structures are allocated.
|
||
|
|
//
|
||
|
|
// Usage:
|
||
|
|
// - Call tiny_mem_stats_add_*() at allocation/free sites (positive/negative).
|
||
|
|
// - Call tiny_mem_stats_dump() when HAKMEM_TINY_MEM_DUMP is set to emit one
|
||
|
|
// summary line to stderr (values reported in KB).
