Added new callbacks phy_enable and set_phy_speed in the mpt2sas_transport_functions template. This will allow end user to enable/disable phys and change links rates using the SysFS interface. Current implementation only supports direct attached phys, but we could in the future add support for expander based phys. A new subroutine mpt2sas_config_set_sas_iounit_pg1 was added; this wrapper function used to send request to controller firmware to modify the phys and link rates. A new subroutine _transport_find_local_phy was added; a function for easly obtaining the local phy object for direct attached. Example to disable a phy echo 0 > /sys/class/phy3:0/enable Example to enable the same phy echo 1 > /sys/class/phy3:0/enable Example to change the link rate to 1.5 #echo "1.5 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 1.5 Gbit Example to change the link rate to 3.0 #echo "3.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 3.0 Gbit Example to change the link rate to 6.0 #echo "6.0 Gbit" > /sys/class/phy3:0/maximum_linkrate #cat /sys/class/phy3:0/negotiated_linkrate 6.0 Gbit Signed-off-by: Kashyap Desai <kashyap.desai@lsi.com> Reviewed-by: Eric Moore <eric.moore@lsi.com> Signed-off-by: James Bottomley <James.Bottomley@suse.de> |
