The -status of each manager is presented in terms of documentation and -status relative to the extended level (level 'E') of the uITRON 3.0 -API specification. The extended level of the specification is -the level at which dynamic object creation, deletion, and -reference services are available. This level is more akin to the other -APIs supported by RTEMS. This purpose of this chapter is -to make it clear what is required to bring the RTEMS -uITRON API implementation into compliance with the -specification. The following description of the specification -levels is taken from the uITRON 3.0 API specification. - - -uITRON 3.0 specification is divided into fewer system call levels than was the -previous uITRON 2.0 specification. There are now just three levels: Level R -(Required), Level S (Standard) and Level E (Extended). In addition to these -three levels, there is also Level C for CPU-dependent system calls. -In addition, the uITRON 3.0 API, defines the network level ('N') which -represents system calls that support the connection function - -@itemize @bullet -@item [level R] (Required) -The functions in this level are mandatory for all implementations of -uITRON 3.0 specification. This includes basic functions for achieving -a real-time, multitasking OS. These functions can be implemented even -without a hardware timer. This level corresponds to Levels 1 and 2 -of uITRON 2.0 specification. - -@item [level S] (Standard) -This includes basic functions for achieving a real-time, multitasking -OS. This level corresponds to Levels 3 and 4 of uITRON 2.0 -specification. - -@item [level E] (Extended) -This includes additional and extended functions. This corresponds to -functions not included in uITRON 2.0 specification (functions of -ITRON2 specification). Specifically, this level includes object -creation and deletion functions, rendezvous functions, memorypools -and the timer handler. - -@item [level C] (CPU dependent) -This level provides implementation-dependent functions required due to -the CPU or hardware configuration. - -@end itemize - -The support level of the connection function is indicated by appending an 'N' -to the end of the level. For example, connectivity supported at [level S] -would be referred to as [level SN]. The support level for functions which -can only send requests for operations on other nodes but offer no system call -processing on the issuing node itself are indicated by the lower case letter -'s' or 'e'. - -@c -@c Task -@c - -@section Task Status - -@itemize @bullet - -@item Implementation -@itemize @bullet -@item cre_tsk - Complete, Pending Review -@item del_tsk - Complete, Pending Review -@item sta_tsk - Complete, Pending Review -@item ext_tsk - Complete, Pending Review -@item exd_tsk - Complete, Pending Review -@item ter_tsk - Complete, Pending Review -@item dis_dsp - Complete, Pending Review -@item ena_dsp - Complete, Pending Review -@item chg_pri - Complete, Pending Review -@item rot_rdq - Complete, Pending Review -@item rel_wai - Stub, Needs to be Fleshed Out -@item get_tid - Complete, Pending Review -@item ref_tsk - Complete, Pending Review - -@item Notes: -@itemize @bullet -@item None -@end itemize - -@end itemize - -@item Executive Modifications -@itemize @bullet -@item None Expected -@end itemize - -@item Testing -@itemize @bullet -@item itron01 - Hello world -@item itron02 - Semaphore test -@item itron03 - directives: ex_init, ex_start, t_create, -t_start, tm_tick, i_return, t_ident, tm_set, tm_get, tm_wkafter -See .doc file, verify correct -@item itron04 - Doc file needed -@item itron05 - directives: ext_tsk, cre_tsk, sta_tsk, rot_rdq -ex_start, t_create, t_start, tm_tick, i_return, t_ident, t_delete, -tm_wkafter, t_setpri, t_suspend -See .doc file, verify correct -@item itron06 - Doc file needed -@item itron07 - Doc file needed -@item itron08 - Doc file needed -@item itron09 - Doc file needed -@item itron10 - Doc file needed -@item tmitron01 - Doc file needed -@item tm_include - Doc file needed.

Accordingly, code at the -beginning and end of an interrupt handler must save and restore any registers -used by the interrupt handler."}@*@* -Based on another comment, in the ret_int description, I think this means -that RTEMS will not support the TA_ASM style of interrupt handlers -- -only the TA_HLNG style.@*@* -@i{When TA_HLNG is specified, a high-level language environment setting -program (a high-level language support routine) is called before branching -to the inthdr address. The least significant bit (LSB) of the system -attribute bits is used for this specification.} - -@item Specification allows special "interrupt-only" versions of system -calls named i???_??? (i.e. sig_sem and isig_sem). This does not seem -to be something that would be implemented with RTEMS. We could provide -macros mapping them onto the default versions if this is an issue. - -@item How this operates versus the behavior of a true TRON chip is -up for discussion. - -@item ret_wup is questionable in only high-level language ISRs. - -@item dis_int and ena_int refer to a specific interrupt number. These -may require hooking back out to the BSP. - -@item for chg_iXX and reg_iXX, the XX should be replaced with something -that is meaningful on a particular CPU. -@end itemize - -@end itemize - -@item Executive Modifications -@itemize @bullet -@item None Expected -@end itemize -
