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.

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.

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 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.

Undefined MALLOC_USE_HASH macro on TileMDE3
Cross-compilation fix for TileraMDE-3.0.1.125620
|
|
Some time ago the driver_async_cancel function was deprecated and slated
for removal in R17. This commit removes the function along with its
associated tests and documentation, sets the
ERL_DRV_EXTENDED_MAJOR_VERSION to 3 and ERL_DRV_EXTENDED_MINOR_VERSION to
0, and modifies the sys_info_base_drv and sys_info_prev_drv tests in the
driver test suite to check version 3.0 instead of 2.0.

|
* lukas/erts/fd0_pipe_bug/OTP-11558:
erts: Make sure fds 0,1 and 2 are open
|
|
If they are not open a really nasty race where the io pipe in
erl_poll got fd 0 and the fd_driver setting fd 0 to blocking
could occur. This caused the emulator to hang during shutdown.
|
|
MALLOC_USE_HASH is not defined in TileraMDE-3, but exists in
TileraMDE-2. So use macro conditionally.

The warning is:
sys/common/erl_poll.c:2513:72: warning: for loop has empty body [-Wempty-body]
for (prev_ps = pollsets; ps != prev_ps->next; prev_ps = prev_ps->next);

New BIF os:unsetenv/1 which deletes an environment variable and
returns 'true'.
Does not change any old functionality.
Calls the libc function unsetenv(3) on UNIX and
SetEnvironmentVariableW(key, NULL) on Windows. The unicode support
is the same as for os:getenv and os:putenv.
|
|
Replaced the +MMscmgc switch with the +MMscrfsd switch. The old switch
didn't reflect what it controlled.
