[PATCH] shpchp: Cleanup improper info messages

2006-06-19T21:13:24+00:00

Current SHPCHP driver shows device number of slots in info messages,
but it is useless and should be replaced with slot name.

This patch replaces the device number shown in the info messages with
the slot name.

[PATCH] shpchp: Fix slot state handling

2006-03-23T22:35:13+00:00

Current SHPCHP driver doesn't care about the confliction between
hotplug operation via sysfs and hotplug operation via attention
button. So if those ware conflicted, slot could be an unexpected
state.

This patch changes SHPCHP driver to handle slot state properly. With
this patch, slot events are handled according to the current slot
state as shown at the Table below.

		Table. Slot States and Event Handling
=========================================================================
Slot State		Event and Action
=========================================================================
STATIC			- Go to POWERON state if user initiates
(Slot enabled,		  insertion request via sysfs
 Slot disabled)		- Go to POWEROFF state if user initiates removal
			  request via sysfs
			- Go to BLINKINGON state if user presses
			  attention button when the slot is disabled
			- Go to BLINKINGOFF state if user presses
			  attention button when the slot is enabled

[PATCH] shpchp: event handling rework

2006-03-23T22:35:13+00:00

The event handler of SHPCHP 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 by using 'work queue', and it
also fix the above-mentioned issue.

[PATCH] shpchp - bugfix: add missing serialization

2006-03-23T22:35:11+00:00

Current shpchp driver might cause system panic because of lack of
serialization. It can be reproduced very easily by the following
operation.

	# cd /sys/bus/pci/slots/
	# while true; do echo 0 > power ; echo 1 > power ; done &
	# while true; do echo 0 > power ; echo 1 > power ; done &

This patch fixes this issue by changing shpchp to get appropreate
semaphore for hot-plug operation.
