      arch-sim: new standard names for the ifaces · 7cd3719d

      arch-sim: removed iface dependencies from net_ops · 57c21fd1
      Pietro Fezzardi authored
      Now you can assign the name you want to the interfaces, because it
      doesn't really look for a physical interface with that name. This
      can be useful to make the diagnostics easier to understand

      arch-sim: changed ports used by the slave · dc463c45
      Pietro Fezzardi authored
      so that you don't need to be administrator to run the simulator and
      you don't have conflicts if there is already a PTP instance running on
      the standard ports

      arch-sim: network operations and main loop · dcddecbc
      Pietro Fezzardi authored
      New struct sim_pending_pkt is introduced to hold information on pakets still in
      fly. An array of such structures is stored in ppg->arch_data. This array is
      written by every send. The insertion is designed to sort automatically the
      packets so that the first element of the array after an insertion is always
      the first packet that will be received. Function sim_fast_forward_ns is changed
      to update also the reception times into this array, so that when you fast
      forward, also the pending packets are fast_forwarded.
      The main loop works in this way:
      	- if there are packets to be received check when
      	- if the first packet to be received is coming before the state machine
      	  timestamps expire, then fast forward till it's time to receive it.
      	  Then receive it and call the state machine of the receiver
      	- if there are no packet pending or the first pending packet is coming
      	  after a timeout, then fast forward till the timeout expires and
      	  run all the state machines

      arch-sim: added per-arch config options · 17a47301
      Pietro Fezzardi authored
      startup is changed, because we need to set the initial time for the
      master before we set the initial offset from master fo the slave.
      In this way the diagnostics cannot be turned on to print out the
      config for the master. This is not a problem, because the master
      it's not meant to be configurable

      arch-sim: new inline functions to select instances · 54eb55be
      Pietro Fezzardi authored
      pp_sim_get_master(ppg) always returns a pointer to master pp_instance.
      pp_sim_get_slave(ppg) always returns a pointer to slave pp_instance.
      pp_sim_is_master(ppi) and pp_sim_is_slave(ppi) are test for obvious
      conditions. these last two can be used only if ppi->glbs != NULL,
      so only if a ppi has been fully initialized.

      arch-sim: fields added to struct sim_ppi_arch_data · 16b4b4e3
      Pietro Fezzardi authored
      These are namely Data Sets, runtime options, servo and TimeProperties.
      We need them in every instance because we have two ppi (master and slave)
      acting like two different machines, so they need different copies of
      these variables. We just put the per-instance stuff in the arch_data.
      Then we'll change the pointers in the ppg directly in the net operations,
      according to our needs.

      time-sim: added time operations · aea3aa29
      Pietro Fezzardi authored
      They're designed to be used for both the instances, master and slave.
      This is possible because the new data structure pp_sim_time_instance
      holding all the information about the time of a single instance is
      placed inside the ppi arch_data

      config: removed global variables current_ppg and current_ppi · 899ab83e
      Pietro Fezzardi authored
      New prototype for cfg_handler to remove the global variable *current_ppg.
      The current ppg is now passed as argument to the cfg handler as follows:
      typedef int (*cfg_handler)(int lineno, struct pp_globals *ppg,
      				union pp_cfg_arg *arg);
      New variable added in include/ppsi/pp-instance.h:
      struct pp_globals_cfg {
      	int cfg_items;
      	int cur_ppi_n;
      Now struct pp_globals has a new field:
      struct pp_globals {
      	struct pp_globals_cfg cfg;
      The field cfg_items has been moved from pp_globals
      to pp_globals_cfg. The configuration routine uses the field
      cur_ppi_n inside pp_globals_cfg to store the current ppi being
      configured. So neither the global variable *current_ppi is needed
      The helper inline function CUR_PPI has been defined to make
      accesses to current ppi more readable.

      arch-wrs: try connecting to HAL multiple times · 6b84951e
      Grzegorz Daniluk authored
      As it was done also in ptp-noposix. We need to try multiple times
      because sometimes it takes time for HAL to become ready (especially in
      the GrandMaster mode when it has to lock SoftPLL to an ext clock).

      lib/conf.c: fix ARG_NONE, factorize code · cd75d6f0
      Pietro Fezzardi authored
      Every case of the switch was colling the cfg_handler out of the
      switch construct, avery time with the same arguments.
      The only case not calling the config function was case ARG_NONE.
      But this doesn't make sense, because if a configuration option
      does not do anything, then it should not be there, even without
      So the call to config function is now made from every case, even
      ARG_NONE, then it should not stay inside the switch.

      configuration: added ARG_TIME config argument · 35456ab1
      Pietro Fezzardi authored
      and all the data structures needed to set configuration options
      about time.
      In ppsi.h added struct pp_cfg_time a platform independent timespec-like
      data structure.
      union pp_cfg_arg is extended with a pp_cfg_time field.
      enum pp_argtype is extended with ARG_TIME.
      In lib/conf.c a case ARG_TIME is added to handle it.
