the slot info. This brings OLDCARD's API much closer to NEWCARD and will allow moving more information into the kernel from pccard.conf for common drivers (ed).

* Slot states for PIOCGSTATE
|
|
*
|
|
* Here's a state diagram of all the possible states:
|
|
*
|
|
* power x 1
|
|
* -------------------
|
|
* / \
|
|
* / v
|
|
* resume +----------+ power x 0 +----------+
|
|
* ------->| inactive |<--------------| filled |
|
|
* / +----------+ +----------+
|
|
* / / \ ^ |
|
|
* nil <--------- \ insert or | | suspend or
|
|
* suspend \ power x 1 | | eject
|
|
* \ | v
|
|
* \ +----------+
|
|
* ----------->| empty |
|
|
* eject +----------+
|
|
*
|
|
* Note, the above diagram is for the state. On suspend, the laststate
|
|
* gets set to suspend to tell pccardd what happened. Also the nil state
|
|
* means that when the no state change has happened. Note: if you eject
|
|
* while suspended in the inactive state, you will return to the
|
|
* empty state if you do not insert a new card and to the inactive state
|
|
* if you do insert a new card.
|
|
*
|
|
* Some might argue that inactive should be sticky forever and
|
|
* eject/insert shouldn't take it out of that state. They might be
|
|
* right. On the other hand, some would argue that eject resets all
|
|
* state. They might be right. They both can't be right. The above
|
|
* represents a reasonable compromise between the two.
|
|
*
|
|
* Some bridges allow one to query to see if the card was changed while
|
|
* we were suspended. Others do not. We make no use of this functionality
|
|
* at this time.
