Added opt.background_thread to enable background threads, which handles purging currently. When enabled, decay ticks will not trigger purging (which will be left to the background threads). We limit the max number of threads to NCPUs. When percpu arena is enabled, set CPU affinity for the background threads as well. The sleep interval of background threads is dynamic and determined by computing number of pages to purge in the future (based on backlog).

/*
|
|
* jemalloc can conceptually be broken into components (arena, tcache, etc.),
|
|
* but there are circular dependencies that cannot be broken without
|
|
* substantial performance degradation.
|
|
*
|
|
* Historically, we dealt with this by each header into four sections (types,
|
|
* structs, externs, and inlines), and included each header file multiple times
|
|
* in this file, picking out the portion we want on each pass using the
|
|
* following #defines:
|
|
* JEMALLOC_H_TYPES : Preprocessor-defined constants and psuedo-opaque data
|
|
* types.
|
|
* JEMALLOC_H_STRUCTS : Data structures.
|
|
* JEMALLOC_H_EXTERNS : Extern data declarations and function prototypes.
|
|
* JEMALLOC_H_INLINES : Inline functions.
|
|
*
|
|
* We're moving toward a world in which the dependencies are explicit; each file
|
|
* will #include the headers it depends on (rather than relying on them being
|
|
* implicitly available via this file including every header file in the
|
|
* project).
|
|
*
|
|
* We're now in an intermediate state: we've broken up the header files to avoid
|
|
* having to include each one multiple times, but have not yet moved the
|
|
* dependency information into the header files (i.e. we still rely on the
|
|
* ordering in this file to ensure all a header's dependencies are available in
|
|
* its translation unit). Each component is now broken up into multiple header
|
|
* files, corresponding to the sections above (e.g. instead of "foo.h", we now
|
|
* have "foo_types.h", "foo_structs.h", "foo_externs.h", "foo_inlines.h").
|
|
*
|
|
* Those files which have been converted to explicitly include their
|
|
* inter-component dependencies are now in the initial HERMETIC HEADERS
|
|
* section. All headers may still rely on jemalloc_preamble.h (which, by fiat,
|
|
* must be included first in every translation unit) for system headers and
|
|
* global jemalloc definitions, however.
