/* BB: IRQ Explanation for VIC
|
||||
* On PB926 there are two interrupt controllers. A secondary IC is
|
||||
* cascaded on the primary, using pin 31. We ack irqs by simply clearing
|
||||
* the status register. We actually ack_and_mask, so for acking, we also
|
||||
* disable the particular irq, on either pic or sic.
|
||||
*
|
||||
* What's more to cascaded irq controllers is that, you may have the
|
||||
* same line number on different controllers, for different irqs. This
|
||||
* causes a difficulty to uniquely identify an interrupt, because the
|
||||
* line number is not a primary key anymore. One approach is to `assume'
|
||||
* irqs on one controller are added to the maximum you can have on the
|
||||
* other. E.g. irq 1 on intctrl P is 1, but irq 1 on intctrl S is
|
||||
* (1 + 31) = 32. While this works, it's not the best approach because
|
||||
* you will see that more complicated architectures on SMP machines are
|
||||
* present. (See PB1176 or EB port, or even worse, try an ARM11MPCore
|
||||
* on EB.)
|
||||
*
|
||||
* What's better is to use a struct to describe what the irq line
|
||||
* `actually' is, so things are put straight, with a small memory
|
||||
* trade-off.
|
||||
*
|
||||
* Furthermore to this, each irq is described uniquely by an irq
|
||||
* descriptor; however, we still need the simplicity of a single integer
|
||||
* to uniquely identify each individual irq. This integer, is the index
|
||||
* of each irq descriptor, in the array of irq descriptors. This index
|
||||
* is not necessarily a natural mapping from irq numbers in interrupt
|
||||
* controllers, as described in paragraph 2, but it is rather a compile-
|
||||
* time constant as far as the compile-time defined irq array is
|
||||
* concerned, or, the set of such primary keys may expand as the array
|
||||
* expands dynamically at run-time (e.g. registration of new irqs at
|
||||
* run-time).

/* BB: IRQ Explanation for VIC
|
||||
* On PB926 there are two interrupt controllers. A secondary IC is
|
||||
* cascaded on the primary, using pin 31. We ack irqs by simply clearing
|
||||
* the status register. We actually ack_and_mask, so for acking, we also
|
||||
* disable the particular irq, on either pic or sic.
|
||||
*
|
||||
* What's more to cascaded irq controllers is that, you may have the
|
||||
* same line number on different controllers, for different irqs. This
|
||||
* causes a difficulty to uniquely identify an interrupt, because the
|
||||
* line number is not a primary key anymore. One approach is to `assume'
|
||||
* irqs on one controller are added to the maximum you can have on the
|
||||
* other. E.g. irq 1 on intctrl P is 1, but irq 1 on intctrl S is
|
||||
* (1 + 31) = 32. While this works, it's not the best approach because
|
||||
* you will see that more complicated architectures on SMP machines are
|
||||
* present. (See PB1176 or EB port, or even worse, try an ARM11MPCore
|
||||
* on EB.)
|
||||
*
|
||||
* What's better is to use a struct to describe what the irq line
|
||||
* `actually' is, so things are put straight, with a small memory
|
||||
* trade-off.
|
||||
*
|
||||
* Furthermore to this, each irq is described uniquely by an irq
|
||||
* descriptor; however, we still need the simplicity of a single integer
|
||||
* to uniquely identify each individual irq. This integer, is the index
|
||||
* of each irq descriptor, in the array of irq descriptors. This index
|
||||
* is not necessarily a natural mapping from irq numbers in interrupt
|
||||
* controllers, as described in paragraph 2, but it is rather a compile-
|
||||
* time constant as far as the compile-time defined irq array is
|
||||
* concerned, or, the set of such primary keys may expand as the array
|
||||
* expands dynamically at run-time (e.g. registration of new irqs at
|
||||
* run-time).
