2011-05-13Reduce number of atomic opsRickard Green
Counters for active, and used schedulers have been coalesced in order to reduce the amount of atomic operations needed. Some currently not strictly necessary barriers have also been added in order to be future proof.
2011-05-13Use 32-bit atomic for port snapshotRickard Green
2011-05-13Remove pointless erts_ports_alive variableRickard Green
2011-05-13Ensure quick breakRickard Green
Make sure that we don't have to wait in poll before break handling is done.
2011-05-13Ensure that all rehashing information are seen when doneRickard Green
This is not a bugfix. The change is done in order to avoid a future bug.
2011-05-13Ensure that stack updates are seen when stack is releasedRickard Green
Ets tables using ordered_set could potentially get into an internally inconsistent state.
2011-05-13Add needed barriers for write_concurrency tablesRickard Green
Ets tables using the write_concurrency option could potentially get into an internally inconsistent state.
2011-05-11Homogenize memory barriers on atomicsRickard Green
Atomic operations with specified barriers have specified barrier semantics. Set and read operations have undefined barrier semantics. All other atomic operations implied full memory barriers, except when using the libatomic_ops library and the tilera atomics api. Some code in the runtime system assumed that all operations used (except for set, read and specified) implied full memory barriers. The use of the libatomic_ops library and the tilera atomics api have therefore been modified to behave as the other implementations. Some atomic operations with specified barrier semantics on sparc32 have also been been relaxed in this commit.

2011-05-02Teach run_erl RUN_ERL_DISABLE_FLOWCNTRL for disabling flow controlJonas Faklkevik
Flow control can cause unwanted behaviour of the beam process, if accidentally hit Ctrl-S (instead of Ctrl-D to detach) the entire beam may be blocked. Fix this problem by making it possible to turn off flow control by setting the environment variable RUN_ERL_DISABLE_FLOWCNTRL.

2011-04-11Fix lost wakeup when process garbage collected by otherRickard Green
2011-04-11Only set status P_WAITING when neededRickard Green
The status of a process was unnecessarily set to waiting before the process was enqueued in a run queue. This bug was harmless up until OTP-R14B01. In OTP-R14B02 erlang:hibernate/3 was fixed (OTP-9125). After the introduction of OTP-9125, the previously harmless process status bug sometimes caused erroneous badarg exceptions from process_info().
