/* A lot of complication here is taken away because:
|
||||
*
|
||||
* 1) We handle one interrupt and return, sitting in a loop and moving across
|
||||
* all the pending IRQ bits in the cause register is _NOT_ the answer, the
|
||||
* common case is one pending IRQ so optimize in that direction.
|
||||
*
|
||||
* 2) We need not check against bits in the status register IRQ mask, that
|
||||
* would make this routine slow as hell.
|
||||
*
|
||||
* 3) Linux only thinks in terms of all IRQs on or all IRQs off, nothing in
|
||||
* between like BSD spl() brain-damage.
|
||||
*
|
||||
* Furthermore, the IRQs on the MIPS board look basically (barring software
|
||||
* IRQs which we don't use at all and all external interrupt sources are
|
||||
* combined together on hardware interrupt 0 (MIPS IRQ 2)) like:
|
||||
*
|
||||
* MIPS IRQ Source
|
||||
* -------- ------
|
||||
* 0 Software (ignored)
|
||||
* 1 Software (ignored)
|
||||
* 2 Combined hardware interrupt (hw0)
|
||||
* 3 Hardware (ignored)
|
||||
* 4 Hardware (ignored)
|
||||
* 5 Hardware (ignored)
|
||||
* 6 Hardware (ignored)
|
||||
* 7 R4k timer (what we use)
|
||||
*
|
||||
* Note: On the SEAD board thing are a little bit different.
|
||||
* Here IRQ 2 (hw0) is wired to the UART0 and IRQ 3 (hw1) is wired
|
||||
* wired to UART1.
|
||||
*
|
||||
* We handle the IRQ according to _our_ priority which is:
|
||||
*
|
||||
* Highest ---- R4k Timer
|
||||
* Lowest ---- Combined hardware interrupt
|
||||
*
|
||||
* then we just return, if multiple IRQs are pending then we will just take
|
||||
* another exception, big deal.
