2017-07-17erts: Replace usage of all erts_smp prefixes to just ertsLukas Larsson
2017-07-17erts: Remove ERTS_SMP and USE_THREAD definesLukas Larsson
This refactor was done using the unifdef tool like this: for file in $(find erts/ -name *.[ch]); do unifdef -t -f defile -o $file $file; done where defile contained: #define ERTS_SMP 1 #define USE_THREADS 1 #define DDLL_SMP 1 #define ERTS_HAVE_SMP_EMU 1 #define SMP 1 #define ERL_BITS_REENTRANT 1 #define ERTS_USE_ASYNC_READY_Q 1 #define FDBLOCK 1 #undef ERTS_POLL_NEED_ASYNC_INTERRUPT_SUPPORT #define ERTS_POLL_ASYNC_INTERRUPT_SUPPORT 0 #define ERTS_POLL_USE_WAKEUP_PIPE 1 #define ERTS_POLL_USE_UPDATE_REQUESTS_QUEUE 1 #undef ERTS_HAVE_PLAIN_EMU #undef ERTS_SIGNAL_STATE
2017-07-06Allow toggling lock counting at runtimeJohn Högberg
The implementation is still hidden behind ERTS_ENABLE_LOCK_COUNT, and all categories are still enabled by default, but the actual counting can be toggled at will. OTP-13170

2017-03-22erts: Improve reduction count during table cleanupSverker Eriksson
2017-03-22erts: Replace meta_pid_to{_fixed}_tab with linked listsSverker Eriksson
from process psd through all owned/fixed tables. As meta_pid_to{_fixed}_tab maps to slot in meta_main_tab which is planned for destruction. In this commit we no longer seize table lock while freeing the table (free_table_cont) as it's not needed and makes the code a bit simpler. Any concurrent operation on the table will only access lock, owner and status and then bail out.
2016-09-19erts: Tweak ets grow/shrink to keep up at contentionSverker Eriksson
2016-09-19erts: Fix ets_SUITE:memorySverker Eriksson
by simply asking for the size of struct ext_segtab
2016-09-19erts: Suppress failed ETS memory checksSverker Eriksson
due to the grow/shrink hysteresis of the meta tables
2016-09-19erts: Redesign ets with separate segment tablesSverker Eriksson
* Keep it simple(r) * To prepare for both dynamic sized segments and segtabs
2016-09-19erts: Remove unnecessary access of 'is_resizing'Sverker Eriksson
in tables without write_concurrency and remove it totally #ifndef ERTS_SMP

2014-06-11erts: Fix cache alignment for ETS write_concurrency locksSverker Eriksson
Effects if sizeof(erts_smp_rwmtx_t) > 64: + Better performance due to less false sharing - Increased memory footprint per table
2014-02-24erts: configure number of write_concurrency locksLukas Larsson
Make it possible to change the number of write_concurrency locks to use. This is usefull to change when you for some reason want to use more/less locks per write_concurrency ets table. eg. OSs with a limit on how many mutexes can exist at once.

2011-10-06ETS: Fix valgrind PossiblyLost in ETS hash tablesSverker Eriksson
Add an extra pointer to start of segment with the active segment table to get rid of PossiblyLost errors without the need of a too general suppression that may hide real memory leaks in ETS.
