Bruce Evans	eec2e836e9	Go back to the old (icu.s rev.1.7 1993) way of keeping the AST-pending ... bit separate from ipending, since this is simpler and/or necessary for SMP and may even be better for UP. Reviewed by: alc, luoqi, tegge	1999-07-10 15:28:01 +00:00
Bruce Evans	18c5a6c435	Implemented dynamic registration of software interrupt handlers. Not ... used yet. Use dummy SWI handlers to avoid some checks for null pointers.	1998-08-11 15:08:13 +00:00
Steve Passe	010e669615	Removed the "globl" nature of the vec array. This was left over from the ... time when icu.s was common between UP and SMP. It is not necessary for UP and thus can be removed from icu_ipl.s.	1997-09-02 19:40:13 +00:00
Steve Passe	886e789627	The last of the encapsolation of cpl/spl/ipending things into a critical ... region protected by the simplelock 'cpl_lock'. Notes: - this code is currently controlled on a section by section basis with defines in machine/param.h. All sections are currently enabled. - this code is not as clean as I would like, but that can wait till later. - the "giant lock" still surrounds most instances of this "cpl region". I still have to do the code that arbitrates setting cpl between the top and bottom halves of the kernel. - the possibility of deadlock exists, I am committing the code at this point so as to exercise it and detect any such cases B4 the "giant lock" is removed.	1997-08-24 00:05:37 +00:00
Steve Passe	81c1993f87	Split vector.s into UP and SMP specific files: ... - vector.s <- stub called by i386/exception.s - icu_vector.s <- UP - apic_vector.s <- SMP Split icu.s into UP and SMP specific files: - ipl.s <- stub called by i386/exception.s (formerly icu.s) - icu_ipl.s <- UP - apic_ipl.s <- SMP This was done in preparation for massive changes to the SMP INTerrupt mechanisms. More fine tuning, such as merging ipl.s into exception.s, may be appropriate.	1997-05-26 17:58:27 +00:00
