- * Handle interrupts generated by the card
- *
- * The MicroChannel Madge cards need slightly more handling
- * after an interrupt than other TMS380 cards do.
- *
- * First we must make sure it was this card that generated the
- * interrupt (since interrupt sharing is allowed). Then,
- * because we're using level-triggered interrupts (as is
- * standard on MCA), we must toggle the interrupt line
- * on the card in order to claim and acknowledge the interrupt.
- * Once that is done, the interrupt should be handlable in
- * the normal tms380tr_interrupt() routine.
- *
- * There's two ways we can check to see if the interrupt is ours,
- * both with their own disadvantages...
- *
- * 1) Read in the SIFSTS register from the TMS controller. This
- * is guaranteed to be accurate, however, there's a fairly
- * large performance penalty for doing so: the Madge chips
- * must request the register from the Eagle, the Eagle must
- * read them from its internal bus, and then take the route
- * back out again, for a 16bit read.
- *
- * 2) Use the MC_CONTROL_REG0_SINTR bit from the Madge ASICs.
- * The major disadvantage here is that the accuracy of the
- * bit is in question. However, it cuts out the extra read
- * cycles it takes to read the Eagle's SIF, as its only an
- * 8bit read, and theoretically the Madge bit is directly
- * connected to the interrupt latch coming out of the Eagle
- * hardware (that statement is not verified).
- *
- * I can't determine which of these methods has the best win. For now,
- * we make a compromise. Use the Madge way for the first interrupt,
- * which should be the fast-path, and then once we hit the first
- * interrupt, keep on trying using the SIF method until we've
- * exhausted all contiguous interrupts.
