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. It supports poll() and select(). 61 62config IPMI_SI 63 tristate 'IPMI System Interface handler' 64 select IPMI_PLAT_DATA 65 help 66 Provides a driver for System Interfaces (KCS, SMIC, BT). 67 Currently, only KCS and SMIC are supported. If 68 you are using IPMI, you should probably say "y" here. 69 70config IPMI_SSIF 71 tristate 'IPMI SMBus handler (SSIF)' 72 depends on I2C 73 help 74 Provides a driver for a SMBus interface to a BMC, meaning that you 75 have a driver that must be accessed over an I2C bus instead of a 76 standard interface. This module requires I2C support. 77 78config IPMI_IPMB 79 tristate 'IPMI IPMB interface' 80 depends on I2C && I2C_SLAVE 81 help 82 Provides a driver for a system running right on the IPMB bus. 83 It supports normal system interface messages to a BMC on the IPMB 84 bus, and it also supports direct messaging on the bus using 85 IPMB direct messages. This module requires I2C support. 86 87config IPMI_POWERNV 88 depends on PPC_POWERNV 89 tristate 'POWERNV (OPAL firmware) IPMI interface' 90 help 91 Provides a driver for OPAL firmware-based IPMI interfaces. 92 93config IPMI_WATCHDOG 94 tristate 'IPMI Watchdog Timer' 95 help 96 This enables the IPMI watchdog timer. 97 98config IPMI_POWEROFF 99 tristate 'IPMI Poweroff' 100 help 101 This enables a function to power off the system with IPMI if 102 the IPMI management controller is capable of this. 103 104endif # IPMI_HANDLER 105 106config IPMI_KCS_BMC 107 tristate 108 109config ASPEED_KCS_IPMI_BMC 110 depends on ARCH_ASPEED || COMPILE_TEST 111 select IPMI_KCS_BMC 112 select REGMAP_MMIO 113 tristate "Aspeed KCS IPMI BMC driver" 114 help 115 Provides a driver for the KCS (Keyboard Controller Style) IPMI 116 interface found on Aspeed SOCs (AST2400 and AST2500). 117 118 The driver implements the BMC side of the KCS contorller, it 119 provides the access of KCS IO space for BMC side. 120 121config NPCM7XX_KCS_IPMI_BMC 122 depends on ARCH_NPCM7XX || COMPILE_TEST 123 select IPMI_KCS_BMC 124 select REGMAP_MMIO 125 tristate "NPCM7xx KCS IPMI BMC driver" 126 help 127 Provides a driver for the KCS (Keyboard Controller Style) IPMI 128 interface found on Nuvoton NPCM7xx SOCs. 129 130 The driver implements the BMC side of the KCS contorller, it 131 provides the access of KCS IO space for BMC side. 132 133 This support is also available as a module.
