fp@194: 
fp@776: Version 1.4.0:
fp@547: 
fp@899: * Remove self_configured flag to avoid unnecessary process data
fp@899:   interruptions.
fp@899: * Replace Sysfs interface with cdev and a user space program
fp@899:   to replace lsec; move a few sysfs attributes to proc.
fp@900: * Implement realtime interface via cdev.
fp@899: * Make scanning and configuration run parallel (each).
fp@866: * Mailbox state machine using toggle bits.
fp@866: * Mailbox protocol handlers.
fp@776: * Remove get_cycles() calls and references to cpu_khz to increase
fp@776:   portability.
fp@776: * Remove ecdb.h and let lsec output PDO information 'cut-and-pastable' for
fp@776:   applications.
fp@819: * SDO write access in sysfs.
fp@776: * Update documentation.
fp@899: * Supply new ec_master_state_t.
fp@833: * Scanning of Sdo dictionary / writing EEPROM in OPERATION state.
fp@845: * Adapt remaining examples.
fp@900: * READMEs for examples.
fp@848: * Separate Pdo and Pdo entry classes.
fp@848: * Attach Pdo names.
fp@855: * Wait for bus scanning, even when link is not up at ecrt_request_master().
fp@857: * Implement ecrt_slave_config_state().
fp@899: * Add something like lsec -n to show numeric vendor IDs.
fp@900: * Remove the end state of the master state machine.
fp@900: * Rename the sdodict state to sdo_dictionary.
fp@900: * Check the position of the acknowledge state.
fp@900: * Remove the xmldev files.
fp@900: * Remove some debugging (add_sync_manager, clearing station addresses).
fp@900: * Separate CoE debugging.
fp@900: * Make ecrt_master_slave_config() return no error when slave is not present
fp@900:   or invalid.
fp@547: 
fp@776: Future issues:
fp@776: 
fp@899: * Distributed clocks.
fp@899: * Move slave handlers and state machines, etc. into a user space daemon (move
fp@899:   kernel threads to user space daemon with a TCP interface replacing the
fp@899:   cdev).
fp@831: * Mailbox gateway.
fp@831: * Slave-to-slave communication.
fp@776: * Redundancy with 2 network adapters.
fp@776: * Interface/buffers for asynchronous domain IO.
fp@776: 
fp@776: Smaller issues:
fp@776: 
fp@866: * Evaluate SII Size field (0x003E) to determine maximum SII memory size.
fp@833: * Unite fsm_pdo_mapping, fsm_pdo_config and fsm_coe_map.
fp@776: * Clear sync managers in INIT.
fp@776: * Simplify FSMs with <state>_enter() functions.
fp@776: * Read out CRC counters.
fp@776: * Optimize alignment of process data.
fp@776: * Evaluate EEPROM contents after writing.
fp@776: * Configure slave ports to automatically open on link detection.
fp@776: * Interrupt master state machines state scan for other jobs.
fp@776: * Master state machine, slave configuration: Do not check every slave on
fp@776:   a cycle.
fp@776: * Only execute one EoE handler per EoE cycle.
fp@776: 
fp@776: Less important issues:
fp@776: 
fp@776: * File access over EtherCAT (FoE).
fp@776: * Allow VLAN tagging.
fp@776: * Determine number of frames, the NIC can handle.
