911465b54c Restructure the IPI code a little, allowing multiple IPIs to be sent at 
once.  Add a way to broadcast an IPI to all processors (except the sender,
obviously).  Add an IPI for TLB shootdown.

2c50ec242f Add basic interprocessor interrupt sending and receiving code. Current 
IPI functions: HALT, IMB, TBIA, TBIAP.

XXX HALT is not yet implemented, it's just a stub.

ad921921e4 Add softserial to the alpha port. This significantly improved PPP 
throughput on com ports.

528dab6808 Implement alpha_shared_intr_disestablish(). Simply removes the handler 
fromthe list, allowing the caller to manipulate the sharing type,
if appropriate.

6054d626f9 Switching dev/ic/lpt.c to use spllpt() instead of spltty(). It doesn't use 
tty structures, and on some machines (namely the DraCo internal lpt, and some
multi-i/o boards for Amigas and DraCos), tying spltty to the pretty high printer
interupt level would hurt serial performance.

On all affected ports but Amiga, spllpt() has been defined in machine/intr.h
to be spltty(), thus preserving old behaviour. Portmasters are encouraged to
change is, if they feel something else is better (e.g., one of its own were
possible).

de83dce0de On second thought, call that like the rest of the shared intr functions. 1998-07-07 22:24:38 +00:00

443d238f70 Define a macro to test if a shared interrupt should be disabled after 
a stray has occurred.

fce829ca4b mark prototypes for static inline functions as possibly unused 
(with __attribute__ ((unused))), to avoid generating warnings when
compiling without optimization but with the default warning flags.

1c33c6bff8 actually, declare _splraise() as an inline function, because: 
(1) it was using 'max', and some functions use a variable
	    of that name (*sigh*), and
	(2) that makes it easier to be a bit trickier, and only call
	    swpipl if changing the IPL.

57c012e265 make sure that splnet(), splbio(), splimp(), spltty(), splclock(), 
splstatclock(), and splhigh() all _raise_ the IPL.  (splhigh() is _not_
the highest possible IPL; mcheck is...)

91c6442ca0 implement a (hack-ish) set of routines to do common chained-interrupt 
handler management.  It's nasty, but three slightly different copies of
the code is worse.
