* arch/m68k/atari/ataints.c -- Atari Linux interrupt handling code
|
|
*
|
|
* 5/2/94 Roman Hodek:
|
|
* Added support for TT interrupts; setup for TT SCU (may someone has
|
|
* twiddled there and we won't get the right interrupts :-()
|
|
*
|
|
* Major change: The device-independent code in m68k/ints.c didn't know
|
|
* about non-autovec ints yet. It hardcoded the number of possible ints to
|
|
* 7 (IRQ1...IRQ7). But the Atari has lots of non-autovec ints! I made the
|
|
* number of possible ints a constant defined in interrupt.h, which is
|
|
* 47 for the Atari. So we can call request_irq() for all Atari interrupts
|
|
* just the normal way. Additionally, all vectors >= 48 are initialized to
|
|
* call trap() instead of inthandler(). This must be changed here, too.
|
|
*
|
|
* 1995-07-16 Lars Brinkhoff <f93labr@dd.chalmers.se>:
|
|
* Corrected a bug in atari_add_isr() which rejected all SCC
|
|
* interrupt sources if there were no TT MFP!
|
|
*
|
|
* 12/13/95: New interface functions atari_level_triggered_int() and
|
|
* atari_register_vme_int() as support for level triggered VME interrupts.
|
|
*
|
|
* 02/12/96: (Roman)
|
|
* Total rewrite of Atari interrupt handling, for new scheme see comments
|
|
* below.
|
|
*
|
|
* 1996-09-03 lars brinkhoff <f93labr@dd.chalmers.se>:
|
|
* Added new function atari_unregister_vme_int(), and
|
|
* modified atari_register_vme_int() as well as IS_VALID_INTNO()
|
|
* to work with it.
