Functionality for scheduling operations at thread progress later
has been introduced.
Deallocation of ETS table structures were previously done by scheduling
misc aux work. Deallocation of process structures (not released yet)
was also implemented this way. Instead of using the misc aux work
functionality these implementation now use the newly introduced
functionality for scheduling operations at thread progress later. By
using this new functionaliy we reduce the amount of memory
allocation/deallocation operations needed.

Improve the enqueue operation of delayed dealloc
Implement delayed aux work wake up
|
|
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.
|
|
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.
|
|
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.

erts/emulator/hipe/hipe_arm.c started out as a clone of hipe_ppc.c,
with #ifdefs to select ARM-specific code. Somehow those #ifdefs
never got cleaned out, resulting in fairly ugly-looking code.
This eliminates the #ifdefs, deletes dead PowerPC-specific code, and
keeps only the ARM-specific code. I've verified that the exact same
assembly code is generated for hipe_arm.c before and after this patch
(if you compile without -g, with -g there are unavoidable changes to
the debug data).

Bug introduced in R15.
|
|
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.
|
|
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.
|
|
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.

Make sure that the the currently running thread has the lock,
not only that that some thread has the lock.
