* rickard/dealloc/OTP-10162: Improve the enqueue operation of delayed dealloc Implement delayed aux work wake up
2012-07-31Use static allocation of process lock queuesRickard Green
By using statically allocated lock queues there is no longer any need for locking corresponding pix lock when process locks have been transferred after a wait. This costs us 3 words extra in process structure, but improves performance during contention.
2012-07-31Improve the enqueue operation of delayed deallocRickard Green
The enqueue operation have been re-written to behave better during heavy contention by spreading writes over multiple locations. This enqueue operation also take advantage of the delayed aux work wake up functionality and can by this omit one memory barrier.
2012-07-31Implement delayed aux work wake upRickard Green
By using a delayed aux work wake up approach, a memory barrier can be omitted in the delayed dealloc enqueue operation. The amount of operations, on the potentially contended, wake up structure is also reduced.

2012-06-25Don't go to single-scheduler mode when managing breakpointsBjörn Gustavsson
Calls to erlang:set_trace_pattern/3 will no longer block all other schedulers. We will still go to single-scheduler mode when new code is loaded for a module that is traced, or when loading code when there is a default trace pattern set. That is not impossible to fix, but that requires much closer cooperation between tracing BIFs and the loader BIFs.
2012-06-25Refactor the code for managing breakpointsBjörn Gustavsson
To allow us to manage breakpoints without going to single-scheduler mode, we will need to update the breakpoints in several stages with memory barriers in between each stage. Prepare for that by splitting up the breakpoint setting and clearing functions into several smaller functions.
2012-06-25Change the data structures for breakpointsBjörn Gustavsson
Change the data structures for breakpoints to make it possible (in a future commit) to manage breakpoints without taking down the system to single-scheduling mode. The current "breakpoint wheel" data structure (a circular, double-linked list of breakpoints) was invented before the SMP emulator. To support it in the SMP emulator, there is essentially one breakpoint wheel per scheduler. As more breakpoint types have been added, the implementation has become messy and hard to understand and maintain. Therefore, the time for a rewrite has come. Use one struct to hold all breakpoint data for a breakpoint in a function. Use a flag field to indicate what different type of break actions that are enabled.
2012-06-25Make the lock check in erts_is_code_ix_locked() strongerBjörn Gustavsson
Make sure that the the currently running thread has the lock, not only that that some thread has the lock.

2012-06-18Fix faulty use of thread progress in handle_aux_work()Rickard Green
As an optimization old thread progress data was kept and used in handle_aux_work() in erl_process.c. This could cause memory to be deallocated at a later time than intended, which is quite harmless. This has, however, now been fixed.

2012-05-11DTrace bug in message-sendzheng siyao
dtrace doesn't print sender pid and receiver pid in message related probe correctly, it truncates pid string to 7 characters on 64bit platform(or 3 characters on 32bit platform). The dtrace related code did not set the string length correctly, it sets the string length to the length of a pointer rather than the buffer length.
2012-05-10Remove stale code for hybrid heap and incremental GCBjörn Gustavsson
The hybrid heap emulator was last working in the non-SMP R11B run-time system. When the constant pools were introduced in R12B, the hybrid heap emulator was not updated to handle them. At this point, the harm from reduced readability of the code is greater than any potential usefulness of keeping the code.
