Create an specific OSE application that mainly contains documentation
around the OSE specific part of Erlang/OTP.
|
|
|
|
This new API has less impact on the check_io code and
also removes the callback from ErlDrvEntry. The downside
is that you have to give the resolve function when creating
each event.
Also the mode if the resolve was removed as this mimics the
win32 code and decreases complexity.
|
|
|
|
For some reason starting with pm_create offsets the
input argument list by one, so we have to adjust them
before calling erl_start.
|
|
|
|
|
|
Use these to switch inbetween debug and non-debug emulators
and 4.4.3 and 4.6.3 versions of gcc.
|
|
Some OSE cross-chains have problems with system includes
being used, so for atleast OSE specific parts we use ""
instead of <>.

This simplified debugging on OSE and also limits the number of ppdata
keys that are created when beam is restarted.
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
There is a system limit on the number of ppdata that is available
but that should not be reached, and ppdata is faster than using
get_envp.
|
|
|
|
The interface of this module is made to be as generic as possible
in order for other IPC mechanisms to mimic it and allow porting of
code between different os:es.
|
|
The old way registered a shell command that needed to be executed. This
way is more flexible as you can also use the lmconf file to set arguments
there.
|
|
|
|
This is needed because OSE does not use 1 for SEEK_CUR
|
|
|
|
This is done in order to catch rogue signals
|
|
This is needed because OSE does not have the same integers
as unix/win32 for SEEK_ST and friends.
|
|
This is needed because a file has to be opened and operated on
in the same process at all times. Using async threads guarantee this.
|
|
|
|
|
|
To enable just uncomment and all signals going in or out will be
printed to stdout.
|
|
Before get_envp was used and this caused the environment
variables to not be accessible in the correct way by
use debug tools.
|
|
The hwfp has been tested as well and seem to work,
but most processors that OSE will run on does not have
a fpu.
|
|
This port has support for both non-smp and smp.
It contains a new way to do io checking in which erts_poll_wait
receives the payload of the polled entity. This has implications
for all linked-in drivers.

further enhancements for dirty schedulers
allow optional whitespace in dirty scheduler erl options

Add support for setting the number of dirty CPU schedulers online via
erlang:system_flag/2. Assuming the emulator is built with dirty schedulers
enabled, the number of dirty CPU schedulers online may not be less than 1,
nor greater than the number of dirty CPU schedulers available, nor greater
than the number of normal schedulers online. Dirty CPU scheduler threads
that are taken offline via system_flag/2 are suspended. The number of dirty
CPU schedulers online may be adjusted independently of the number of normal
schedulers online, but if system_flag/2 is used to set the number of normal
schedulers online to a value less than the current number of normal
schedulers online, the number of dirty CPU schedulers online is decreased
proportionally. Likewise, if the number of normal schedulers online is
increased, the number of dirty CPU schedulers online is increased
proportionally. For example, if 8 normal schedulers and 4 dirty CPU
schedulers are online, and system_flag/2 is called to set the number of
normal schedulers online to 4, the number of dirty CPU schedulers online is
also decreased by half, to 2. Subsequently setting the number of normal
schedulers online back to 8 also sets the number of dirty CPU schedulers
online back to 4. Augment the system_flag/2 documentation in the erlang man
page to explain this relationship between schedulers_online and
dirty_cpu_schedulers_online.
Also ensure that all dirty CPU and I/O schedulers are suspended when
multi-scheduling is blocked via system_flag/2, and brought back online when
multi-scheduling is unblocked.
Add Rickard Green's rewritten check_enqueue_in_prio_queue() function that
inspects process state more thoroughly to determine if to enqueue it and if
so on what queue, including dirty queues when appropriate.
Make sure dirty NIF jobs do not trigger erlang:system_monitor long_schedule
messages.
Add more dirty scheduler testing to the scheduler test suite.
Remove the erts_no_dirty_cpu_schedulers_online global variable, since it's
no longer needed.
Execute dirty NIFs on a normal scheduler thread while multi-scheduling
blocking is in effect. Evacuate any dirty jobs residing in the dirty run
queues over to a normal run queue when multi-scheduling is blocked.
Allow dirty schedulers to execute aux work.
Set the dirty run queues halt_in_progress flag when halting the normal
schedulers.
Change dirty scheduler numbers to a structure including both scheduler
number and type, either dirty CPU or dirty I/O. Add some assertions to
ensure that dirty CPU schedulers operate only on dirty CPU scheduler
process flags, and the same for dirty I/O schedulers.

Commit e5c71b7 deprecated several all functions in the asn1rt
module. As a result, calls to those functions from test suites
caused warnings, and as the warnings_as_errors option was active,
two test files failed to compile.
