Needed to get std io to work in some OSE systems where stdio
is not opened when the program starts.

As any scheduler process can consume any message we have
to make sure that the message is owned by the scheduler
before returning it in erl_drv_ose_get_signal.

If writev return an error (eg ENOSPC) we do not want to abort here
but instead propagate upwards into erlang.

Schedulers is too restrictive. Managed threads should be
able to clean this up.
|
|
The pattern used for getting the priority from the lmconf
is based on the name of the process created. The pattern is:
ERTS_%%PROCESS_NAME%%_PRIO
with the %%PROCESS_NAME%% replaced by the prefix of the process
the priority applies to. eg:
ERTS_SCHEDULER_PRIO=24
applies to processes with name SCHEDULER_1, SCHEDULER_2 etc.
|
|
Now schedulers 2..N make sure to wake sched 1 if they
find that all io has been consumed and sched 1 is
sleeping. Before sched 1 was spinning in sys_schedule
waiting for sched 2..N to finish consuming io jobs
|
|
Also removed softkernel lcf files.
|
|
When opening filers on not mounted volumes the default
timeout on OSE is quite big and since at startup we load
something like 20 beam files this slows down startup by
as much as 50 seconds.
|
|
Also deleted all the copy-paste stuff
|
|
This is needed on OSs that do not do round robin scheduling
of threads.
|
|
|
|
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.
|
|
|
|
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.

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 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.
|
|
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.
