* 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.

/*
|
|
* Atari interrupt handling scheme:
|
|
* --------------------------------
|
|
*
|
|
* All interrupt source have an internal number (defined in
|
|
* <asm/atariints.h>): Autovector interrupts are 1..7, then follow ST-MFP,
|
|
* TT-MFP, SCC, and finally VME interrupts. Vector numbers for the latter can
|
|
* be allocated by atari_register_vme_int().
|
|
*
|
|
* Each interrupt can be of three types:
|
|
*
|
|
* - SLOW: The handler runs with all interrupts enabled, except the one it
|
|
* was called by (to avoid reentering). This should be the usual method.
|
|
* But it is currently possible only for MFP ints, since only the MFP
|
|
* offers an easy way to mask interrupts.
|
|
*
|
|
* - FAST: The handler runs with all interrupts disabled. This should be used
|
|
* only for really fast handlers, that just do actions immediately
|
|
* necessary, and let the rest do a bottom half or task queue.
|
|
*
|
|
* - PRIORITIZED: The handler can be interrupted by higher-level ints
|
|
* (greater IPL, no MFP priorities!). This is the method of choice for ints
|
|
* which should be slow, but are not from a MFP.
|
|
*
|
|
* The feature of more than one handler for one int source is still there, but
|
|
* only applicable if all handers are of the same type. To not slow down
|
|
* processing of ints with only one handler by the chaining feature, the list
|
|
* calling function atari_call_irq_list() is only plugged in at the time the
|
|
* second handler is registered.
|
|
*
|
|
* Implementation notes: For fast-as-possible int handling, there are separate
|
|
* entry points for each type (slow/fast/prio). The assembler handler calls
|
|
* the irq directly in the usual case, no C wrapper is involved. In case of
|
|
* multiple handlers, atari_call_irq_list() is registered as handler and calls
|
|
* in turn the real irq's. To ease access from assembler level to the irq
|
|
* function pointer and accompanying data, these two are stored in a separate
|
|
* array, irq_handler[]. The rest of data (type, name) are put into a second
|
|
* array, irq_param, that is accessed from C only. For each slow interrupt (32
|
|
* in all) there are separate handler functions, which makes it possible to
|
|
* hard-code the MFP register address and value, are necessary to mask the
|
|
* int. If there'd be only one generic function, lots of calculations would be
|
|
* needed to determine MFP register and int mask from the vector number :-(
|
|
*
|
|
* Furthermore, slow ints may not lower the IPL below its previous value
|
|
* (before the int happened). This is needed so that an int of class PRIO, on
|
|
* that this int may be stacked, cannot be reentered. This feature is
|
|
* implemented as follows: If the stack frame format is 1 (throwaway), the int
|
|
* is not stacked, and the IPL is anded with 0xfbff, resulting in a new level
|
|
* 2, which still blocks the HSYNC, but no interrupts of interest. If the
|
|
* frame format is 0, the int is nested, and the old IPL value can be found in
|
|
* the sr copy in the frame.
