Hi all, I have following hardware configuration based on Pigeon Point BMC
PowerPC MPC8560 SCC ------UART----IPMI Serial Interface(Terminal Mode)---->BMR-AVR BMC As I am not much aware about IPMI I shall be grateful if anyone can clear my doubts Software Available OS : linux kernel 2.6.21 on Host processor Driver : SCC (CPM2 UART) driver (Serial Driver) available with Linux Kernel, OpenIPMI Linux Driver patches Host processor : MPC8560 (ppc) The host processor is MPC8560 (Motorola ppc) and its Serial Communication controller is connected to BMC(BMR-AVR) over Serial Interface. The mode required is Terminal Mode as defined in IPMI Specs 1.5. The protocol run on this interface is pigeon Point SIPL (Serial protocol interface lite) My task is to write a user mode application in linux which issues commands over this serial interface to BMC and get the responses. I have two doubts (1) My doubt is regarding software stacking of the various drives and my applicatiom . Layer 1 -> My Application Layer 2 -> openipmilib Layer 3 -> ipmi_devintf Layer 4 -> ipmi_msghandler Layer 5 -> ipmi_serial Layer 6 -> ipmi_serial_terminal_mode Layer 7 -> Serial Driver (MPC8560 SCC) Do ipmi_msghandler use DDI exported by ipmi_serial ? Extactly how a msg sent from userspace travel down to Serial Driver. (2) Pigeon point BMR supports two types of commands Type 1 : Raw IPMI messages of form [Netfn,Seq,cmd,data] and Type 2 : PPS Extension commands of form [NetFn,Seq,cmd,PPS IANA, data] where is PPS IANA is to be introduced in command. In userspace application while preparing a command or it is introduced by ipmi_serial_terminal_mode codec before sending it on serial interface?? I shall be grateful if anyone kindly clear my doubts Thanks in advance, with regards, Deepak Gaur Deepak Gaur ------------------------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
