src/sys/dev/pci: ppb.c ppbvar.h
Log Message:
Enable PCIe's interrupt as much as possilbe in ppb(4) to detect and count
status change event. HotPlug function itself have not implemented yet.
- Interrupt and each event are counted by evcnt(9). Example:
ppb0 Interrupt 0 0 intr
ppb0 Attention Button Pressed 0 0 misc
ppb0 Power Fault Detected 0 0 misc
ppb0 MRL Sensor Changed 0 0 misc
ppb0 Presence Detect Changed 0 0 misc
ppb0 Command Completed 0 0 misc
ppb0 Data Link Layer State Changed 0 0 misc
- Print message if ppb_printevent is not zero. The default vaule is 0.
The output messages:
Attention Button Pressed
Power Fault Detected
MRL Sensor Changed
Presence Detect Changed
Command Completed
Data Link Layer State Changed
- Remove workaround code to disable interrupt (ppb.c rev. 1.35).
Tested with Dell Latitude 2120 without if_bge.c rev. 1.304's workaround.
dmesg when bge's device timeout occured:
ppb3: Presence Detect Changed
ppb3: Data Link Layer State Changed
ppb3: Presence Detect Changed
vmstat -e |grep ppb
ppb3 Interrupt 2 0 intr
ppb3 Presence Detect Changed 2 0 misc
ppb3 Data Link Layer State Changed 1 0 misc
