Overview========The uITRON module on top of Xenomai currently implements the followingservices:Known variations from the uITRON 3.02 specification===================================================- Generally speaking, the verification of address parameters is notperformed by the uITRON API. Running your application on top of theMVM is _always_ a good idea to detect memory reference problems moreeasily.Implementation-dependent characteristics========================================- Task identifiers must be strictly positive. Passing zero or anegative task identifier to the API always beget the E_ID error,therefore E_OACV is never returned.- cre_tsk(): * Task priority may range from 1 to 8 (included). * Task attributes are ignored, therefore E_RSATR is never returned. * E_PAR is returned when the given stack size is lower than 1Kbyte.- ext_tsk():- exd_tsk(): * Upon error, these system calls cause the uITRON API to abort.- rot_rdq(): * implements the [Level X] cyclic handler feature as defined by the   uITRON 3.02 specification. When called on behalf of a   task-independent portion, the ready queue including the running   task is rotated.- ref_tsk(): * Since the verification of address parameters is not performed by   the uITRON API, E_PAR is never returned. * Implements [Level X] except for pk_rtsk->wid which is currently   returned as zero in ALL cases.- sus_tsk(): * Implements [Level X] suspend request nesting feature. The maximum   nesting count is 0x7fffffff. Nesting overflow results in E_QOVR   being returned.- rsm_tsk(): * Implements [Level X] suspend request nesting feature.- tsk_slp(): * A zero timeout value immediately begets an E_TMOUT error return   with no delay applied.- wup_tsk(): * Implements [Level X] wakeup request queuing feature. The maximum   queing count is 0x7fffffff. Queuing overflow results in E_QOVR   being returned.- cre_sem(): * Implements [Level X] priority queuing and maximum semaphore count   features.- ref_sem(): * Implements [Level X] waiter information feature (pk_rsem->wtsk is   always defined on return).- cre_flg(): * Implements [Level X] multiple waiters feature.- ref_flg(): * Implements [Level X] waiter information feature (pk_rflg->wtsk is   always defined on return).- cre_mbx(): * Implements [Level X] task priority queuing feature but NOT the message priority queuing since a buffer ring is used for storing messages instead of a linear list. E_PAR is returned whenever pk_cmbx->bufcnt is lower than or equal to zero.- ref_mbx(): * Implements [Level X] waiter information feature (pk_rmbx->wtsk is   always defined on return).Module parameters=================The following parameters can be passed at startup to the uITRONAPI module:- "tick_hz_arg", clock tick period. Defaults to 100 Hz.
