pciehp: Event handling rework

2007-05-03T02:02:34+00:00

The event handler of PCIEHP driver is unnecessarily very complex. In
addition, current event handler can only a fixed number of events at
the same time, and some of events would be lost if several number of
events happened at the same time.

This patch simplify the event handler using 'work queue', and it also
fix the above-mentioned issue.

this was spotted by coverity (cid #819). We dereference p_slot
earlier in the function, and i found no way it could become NULL
anywhere.

pciehp - add missing locking

2006-10-18T18:36:10+00:00

This patch fixes the problem that system will panic if multiple power
on/off operations are issued to the same slot in parallel. This
problem can be easily reproduced by commands below.

    # while true; do echo 1 > power; echo 0 > power; done &
    # while true; do echo 1 > power; echo 0 > power; done &

The cause is lack of locking for enable/disable operations. This patch
fixes this problem.

Furthermore, those slot number is not same as slot name (directory
name). This patch fixes those improper info messages.
