* rickard/ds-sched-suspend:
Improved scheduler suspend functionality
|
|
- The calling process is now suspended while synchronizing
scheduler suspends via erlang:system_flag(schedulers_online, _)
and erlang:system_flag(multi_scheduling, _), instead of blocking
the scheduler thread in the BIF call waiting for the operation
to synchronize. Besides releasing the scheduler for other work
(or immediate suspend) it also makes it possible to abort the
operation by killing the process.
- erlang:system_flag(schedulers_online, _) now only wait for normal
schedulers to complete before it returns. This since it may take
a very long time before all dirty schedulers suspends.
- erlang:system_flag(multi_scheduling, block_normal|unblock_normal)
which only operate on normal schedulers has been introduced. This
since there are use cases where suspend of dirty schedulers are
not of interest (hipe loader).
- erlang:system_flag(multi_scheduling, block) still blocks all
dirty schedulers as well as all normal schedulers except one since
it is hard to redefine what multi scheduling block means.
- The three operations:
- changing amount of schedulers online
- blocking/unblocking normal multi scheduling
- blocking/unblocking full multi scheduling
can now be done in parallel. This is important since otherwise
a full multi scheduling block would potentially delay the other
operations for a very long time.

Just mask away the high bits to get a more tolerant erlang:halt
that behaves the same on 32 and 64 bit architectures.
|
|
|
|
Except it cannot be disabled and cannot be multi-threaded.
The bit-vector 'erts_literal_vspace_map' on 32-bit is currently only
protected by the literal allocator mutex. We could allow multiple
instances on 64-bit (I think), but what would be the point?

Allow IPv6 nodes to register with and query epmd. On systems with
IPv6 support:
* epmd listens on both the IPv4 and IPv6 ANY or loopback sockets
* the epmd cli client connects to epmd over the IPv6 loopback
* distributed nodes started with "-proto_dist inet6_tcp" will register
with epmd over IPv6
To work on IPv6 capable systems that have IPv6 support disabled,
epmd ignores errors opening the socket if the protocol is not
supported. Similarly, the epmd client will fall back to IPv4 if the IPv6
socket is not available.
Update the minimum supported version of Windows to Windows Vista to
support IPv6.

Microstate accounting is a way to track which state the
different threads within ERTS are in. The main usage area
is to pin point performance bottlenecks by checking which
states the threads are in and then from there figuring out
why and where to optimize.
Since checking whether microstate accounting is on or off is
relatively expensive if done in a short loop only a few of the
states are enabled by default and more states can be enabled
through configure.
I've done some benchmarking and the overhead with it turned off
is not noticible and with it on it is a fraction of a percent.
If you enable the extra states, depending on the benchmark,
the ovehead when turned off is about 1% and when turned on
somewhere inbetween 5-15%.

The perf_counter is a very very cheap and high resolution timer
that can be used to timestamp system events. It does not have
monoticity guarantees, but should on most OS's expose a monotonous
time.
A special instruction has been created for this counter to further
speed up fetching it.

Custom loaders are no longer supported. Most of the documentation
for them were removed in c8a7d2d7.
|
|
The 'init' module fetches command line parameters and passes them
to erl_prim_loader:start/3.
The code can be simplified if 'init' calls a new
erl_prim_loader:start/0 function that itself fetches the necessary
command line parameters. Also remove the documentation for the start()
function, since it there is no way that it can be usefully called by
a user application.
While we are at it, also get rid of '-id' command line parameter,
which is fetched and stored but never actually used.
