+ <libsummary>Linked-in drivers in Enea OSE</libsummary>
+ <description>
+ <p>Writing Linked-in drivers that also work on Enea OSE is very similar for
+ how you would do it for Unix. The difference from Unix is that
+ driver_select, ready_input and ready_output all work with signals
+ instead of file descriptors. This means that the driver_select is
+ used to specify which type of signal should trigger calls to
+ ready_input/ready_output. The functions described below are available
+ to driver programmers on Enea OSE to facilitate this.

+ <title>Starting Erlang/OTP</title>
+ <p>
+ Starting Erlang/OTP on OSE is not as simple as on Unix/Windows (yet).
+ First of all you have to explicitly use the beam (or beam.smp) executables
+ found in erts-X.Y.Z/bin as the load module that you run. This in turn
+ means that you have to supply the raw beam arguments to the emulator
+ when starting. Fortunately <c>erl</c> on Unix/Windows has a
+ undocumented flag called <c>-emu_args_exit</c> that can be used to
+ figure out what the arguments to beam look like. For example:</p>
+ <code># erl +Mut false +A 10 +S 4:4 +Muycs256 +P 2096 +Q 2096 -emu_args_exit
+-Mut
+false
+-A
+10
+-S
+4:4
+-Muycs256
+-P
+2096
+-Q
+2096
+--
+-root
+/usr/local/lib/erlang
+-progname
+erl
+--
+-home
+/home/erlang
+--</code>
+ <p>
+ The arguments are printed on seperate lines to make it possible to know
+ what has to be quoted with &quot;. Each line is one quotable unit.
+ So taking the arguments above you can supply them to pm_create or
+ just execute directly on the command line. For example:</p>
+ <code>rtose@acp3400> pm_install erlang /mst/erlang/erts-6.0/bin/beam.smp
+rtose@acp3400> pm_create -c ARGV="-Mut false -A 10 -S 4:4 -Muycs256 -P 2096 -Q 2099 -- -root /mst/erlang -progname erl -- -home /mst/erlang --" erlang
+pid: 0x110059
+rtose@acp3400> pm_start 0x110059</code>
+ <p>
+ Also note that since we are running erl to figure out the arguments on a
+ seperate machine the paths have to be updated. In the example above
+ <c>/usr/local/lib/erlang</c> was replaced by <c>/mst/erlang/</c>. The
+ goal is to in future releases not have to do the special argument handling
+ but for now (17.0-rc2) you have to do it.
+ </p>
+ <note>
+ Because of a limitation in the way the OSE handles stdio when starting
+ load modules using pm_install/create the Erlang shell only reads every
+ other command from stdin. However if you start Erlang using run_erl
+ you do not have this problem. So it is highly recommended that you
+ start Erlang using run_erl.
+ </note>
+ </section>
+
+ <section>
+ <title>run_erl and to_erl</title>
+ <p>
+ In OSE run_erl and to_erl are combined into a single load module called
+ run_erl_lm. Installing and starting the load module will add two new
+ shell commands called run_erl and to_erl. They work in exactly the same
+ way as the unix variants of run_erl and to_erl, except that the read
+ and write pipes have to be placed under the /pipe vm. One additional
+ option also exists to run_erl on ose:
+ <taglist>
+ <tag><c>-block Name</c></tag>
+ <item>The name of the install handle and block that will be created/used by
+ installing and exectuting the first part of the command. If nothing
+ if given the basename of the load module will be used for this value.
+ Example:
+ <code>pm_install erlang /path/to/erlang/vm/beam.smp
+run_erl -daemon -block erlang /pipe/ /mst/erlang_logs/ "beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"</code>
+ </item>
+ </taglist>
+ The same argument munching as when starting Erlang/OTP without run_erl
+ has to be done. If <c>-daemon</c> is given then all error printouts
+ are sent to the ramlog.
+ See also
+ <seealso marker="erts:run_erl">run_erl</seealso> for more details.
+ </p>
+ <p>
+ Below is an example of how to get started with <c>run_erl_lm</c>.
+ <code>rtose@acp3400> pm_install run_erl_lm /mst/erlang/erts-6.0/bin/run_erl_lm
+rtose@acp3400> pm_create run_erl_lm
+pid: 0x1c005d
+rtose@acp3400> pm_start 0x1c005d
+rtose@acp3400> mkdir /mst/erlang_log
+rtose@acp3400> run_erl -daemon /pipe/ /mst/erlang_log/ "/mst/erlang/erts-6.0/bin/beam.smp -A 1 -- -root /mst/erlang -- -home /mst --"
+rtose@acp3400> to_erl
+Attaching to /pipe/erlang.pipe.1 (^C to exit)
+os:type().
+{ose,release}
+2>
+'to_erl' terminated.</code>
+ Note that Ctrl-C is used instead of Ctrl-D to exit the to_erl shell.
+ </p>

+ <title>epmd</title>
+ <p>
+ In OSE epmd will not be started automatically so if you want to use
+ Erlang distribution you have to manually start epmd.
+ </p>
+ </section>
+
+ <section>
+ <title>VM Process Priorities</title>
+ <p>
+ It is possible to set the priorities you want for the OSE processes that
+ thr emulator creates in the lmconf. An example of how to do it can be
+ found in the default lmconf file in
+ $ERL_TOP/erts/emulator/sys/ose/default.lmconf.

+ <title>Introduction</title>
+ <p>The main way which programs on Enea OSE interact is through the
+ usage of message passing, much the same way as Erlang processes
+ communicate. There are two ways in which an Erlang programmer can
+ interact with the signals sent from other Enea OSE processes; either
+ through the provided <c>ose</c> module, or by writing a custom linked-in
+ driver. This User's Guide describes and provides examples for both
+ approaches.

+ <title>Signals in Erlang</title>
+ <p>Erlang/OTP on OSE provides a erlang module called
+ <seealso marker="ose:ose">ose</seealso> that can be used to interact
+ with other OSE processes using message passing. The api in the module
+ is very similar to the native OSE api, so for details of how the
+ functions work please refer to the official OSE documenation. Below
+ is an example usage of the API.

+ <title>Signals in a Linked-in driver</title>
+ <p>
+ Writing Linked-in drivers for OSE is very similar to how it is done
+ for Unix/Windows. It is only the way in which the driver subscribes
+ and consumed external events that is different. In Unix (and Windows)
+ file descriptiors (and Event Objects) are used to select on. On OSE
+ we use signals to deliver the same functionality. There are two large
+ differences between a signal and an fd.
+ </p>
+ <p>
+ In OSE it is not possible for a signal number to be a unique identifier
+ for a resource in the same way as an fd is. For example; let's say we
+ implement a driver that does an asynchronous hunt that uses signal
+ number 1234 as the hunt_sig. If we want to be able to have multiple
+ hunt ports running at the same time we have to have someway of routing
+ the signal to the correct port. This is achieved by supplying a secondary
+ id that can be retrieved through the meta-data or payload of the signal,
+ e.g:
+ <code>ErlDrvEvent event = erl_drv_ose_event_alloc(1234,port,resolver);</code>
+ The event you get back from
+ <seealso marker="ose_erl_driver#erl_drv_ose_event_alloc">
+ erl_drv_ose_event_alloc</seealso> can then be used by
+ <seealso marker="erts:erl_driver#driver_select">driver_select</seealso>
+ to subscribe to signals. The first argument is just the signal number
+ that we are interested in. The second is the id that we choose to use,
+ in this case the port id that we got in the
+ <seealso marker="erts:driver_entry#start">start</seealso> callback is
+ used. The third argument is a function pointer to a function that can
+ be used to figure out the id from a given signal. The fourth argument can
+ point to any additional data you might want to associate with the event.
+ There is a complete. You can examine the data contained in the event with
+ <seealso marker="ose_erl_driver#erl_drv_ose_event_fetch">erl_drv_ose_event_fetch</seealso>
+ , eg:
+ <code>erl_drv_ose_event_fetch(event, &amp;signal, &amp;port, (void **)&amp;extra);</code>
+ example of what this could look like in
+ <seealso marker="#example">the next section</seealso>.
+ <note>It is very important to issue the driver_select call before
+ any of the signals you are interested in are sent. If driver_select
+ is called after the signal is sent, there is a high probability that it
+ will be lost.</note>
+ </p>
+ <p>
+ The other difference from unix is that in OSE the payload of the event
+ (i.e. the signal data) is already received when the ready_output/input
+ callbacks are called. This means that you access the data of a signal
+ by calling <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
+ erl_drv_ose_get_signal</seealso>. Additionally multiple signals might be
+ associated with the event, so you should call
+ <seealso marker="ose_erl_driver#erl_drv_ose_get_signal">
+ erl_drv_ose_get_signal</seealso> until <c>NULL</c> is returned.
