This is always 36 available, the module parameter for ipmi_msghandler named 37 panic_op can be set to "event" to chose this value, this config 38 simply causes the default value to be set to "event". 39 40config IPMI_PANIC_STRING 41 bool 'Generate OEM events containing the panic string' 42 depends on IPMI_PANIC_EVENT 43 help 44 When a panic occurs, this will cause the IPMI message handler to, 45 by default, generate IPMI OEM type f0 events holding the IPMB 46 address of the panic generator (byte 4 of the event), a sequence 47 number for the string (byte 5 of the event) and part of the 48 string (the rest of the event). Bytes 1, 2, and 3 are the normal 49 usage for an OEM event. You can fetch these events and use the 50 sequence numbers to piece the string together. This config 51 parameter sets the default value to generate these events, 52 the module parameter for ipmi_msghandler named panic_op can 53 be set to "string" to chose this value, this config simply 54 causes the default value to be set to "string". 55 56config IPMI_DEVICE_INTERFACE 57 tristate 'Device interface for IPMI' 58 help 59 This provides an IOCTL interface to the IPMI message handler so 60 userland processes may use IPMI.
