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. - */ - -#if 0 - -#define NUM_INT_SOURCES (8 + NUM_ATARI_SOURCES) - -typedef void (*asm_irq_handler)(void); - -struct irqhandler { - irqreturn_t (*handler)(int, void *, struct pt_regs *); - void *dev_id; -}; - -struct irqparam { - unsigned long flags; - const char *devname; -}; - -/* - * Array with irq's and their parameter data.
