I cannot get disable_slot called when i echo 0 > /sys/bus/pci/devices/0000\:04\:0d.0/power/state i don't know why.. so i let it with explicit call to disable_slot ..it does= =20 not bother me much.. but i would like to do it in the ritgh way.. the user = program have to poll the enum bit of enum port? it is already done by=20 cpcihp_generic driver.. > > I also have to expand the code to support all my 3 hotplug controllers= =20 > > (one on another ..as is seen in my lspci ) if you have some warnings for > > me..please let me know.. > > If you have 3 separate hotplug controllers (separate ENUM# signalling), > watching different buses, then the current driver won't handle that > without some significant rework.

I did not notice that i can register only buses .. i implemented all the st= uff=20 to also register all the controllers .. and can echo 0 > /sys/bus/pci/devices/0000\:04\:0d.0/power/state work if i registered only one controller? (anyway this part does not work now..so i could register only one..) I have 3 hotplug controllers with one ENUM# signal (port 0x0286 bit 2)...a= nd=20 if i had 3 separate ENUM# sources i should only change the query_enum=20 function.. tanks Igor ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
