[ECOS] On ecos interrupt process

[=?gb2312?B?1cUgwcE=?= <johnsonest at hotmail dot com>]

Hi,nickg.
  i am confused that ecos interrupt process:
  for example:
    ISR
      |
    int_end()
        {
           post dsr;
          ....                (branch 1)
           unlocks scheduler()------------------|
        (branch 2)                              |
        }                                       | 
       |                                        |
    restore int                                 |
     return from int                            |
                                                |*********
                                           call  all dsr and wake higher 
threads
                                                hal_switch _context()
                                                 
     my question is whether branch1 is excuted in interrupt level,if yes,
interrupt disable period is too long even use DSR machanism,if not,where 
exit interrupt level?
