KCS全称是Keyboard Controller Style关于这个名称不用过多的追究只需要知道它是系统BIOS和OS和BMC通信的一种基本方式即可。本文将介绍BIOS下的KCS接口包括接口使用方式和数据。内容参考自《ipmi-second-gen-interface-spec-v2-rev1-1.pdf》和https://github.com/microsoft/mu_feature_ipmi.git代码。
KCS数据
BIOS和BMC的交互通过Request和Response的方式所以对应的数据也有两种首先是Request 参数说明如下
NetFn/CmdIPMI命令有不同的分组通过NetFn/Cmd命令字的方式来索引在IPMI命令介绍会进一步说明。LUNLogical Unit Number占据8个比特中的最低两个对于通过KCS向BMC发送的数据LUN的值都是00b。DataIPMI命令的实际请求数据。
然后是Response 其它参数跟Request类似只是多了一个Complete Code说明如下
Completion CodeIPMI命令的返回状态具体的取值如下
//
// Generic Completion Codes definitions
//
#define IPMI_COMP_CODE_NORMAL 0x00
#define IPMI_COMP_CODE_NODE_BUSY 0xC0
#define IPMI_COMP_CODE_INVALID_COMMAND 0xC1
#define IPMI_COMP_CODE_INVALID_FOR_GIVEN_LUN 0xC2
#define IPMI_COMP_CODE_TIMEOUT 0xC3
#define IPMI_COMP_CODE_OUT_OF_SPACE 0xC4
#define IPMI_COMP_CODE_RESERVATION_CANCELED_OR_INVALID 0xC5
#define IPMI_COMP_CODE_REQUEST_DATA_TRUNCATED 0xC6
#define IPMI_COMP_CODE_INVALID_REQUEST_DATA_LENGTH 0xC7
#define IPMI_COMP_CODE_REQUEST_EXCEED_LIMIT 0xC8
#define IPMI_COMP_CODE_OUT_OF_RANGE 0xC9
#define IPMI_COMP_CODE_CANNOT_RETURN 0xCA
#define IPMI_COMP_CODE_NOT_PRESENT 0xCB
#define IPMI_COMP_CODE_INVALID_DATA_FIELD 0xCC
#define IPMI_COMP_CODE_COMMAND_ILLEGAL 0xCD
#define IPMI_COMP_CODE_CMD_RESP_NOT_PROVIDED 0xCE
#define IPMI_COMP_CODE_FAIL_DUP_REQUEST 0xCF
#define IPMI_COMP_CODE_SDR_REP_IN_UPDATE_MODE 0xD0
#define IPMI_COMP_CODE_DEV_IN_FW_UPDATE_MODE 0xD1
#define IPMI_COMP_CODE_BMC_INIT_IN_PROGRESS 0xD2

#define IPMI_COMP_CODE_INSUFFICIENT_PRIVILEGE 0xD4
#define IPMI_COMP_CODE_UNSUPPORTED_IN_PRESENT_STATE 0xD5
#define IPMI_COMP_CODE_SUBFUNCTION_DISABLED 0xD6
#define IPMI_COMP_CODE_UNSPECIFIED 0xFFDataIPMI命令的实际响应数据。
需要注意无论是Request还是Response其数据部分都可以是空的。
另外还有一种稍微特殊一点的KSC数据用来上报事件信息 其实就是一种IPMI命令数据而已。
KSC通信
KSC接口定义了一组IO寄存器通过它们就可以完成与BMC的交互这组寄存器的基地址基本上已经固定
gIpmiFeaturePkgTokenSpaceGuid.PcdIpmiIoBaseAddress|0xCA2|UINT16|0xF000000A为了使用该地址首先需要打开它的映射代码如下所示
/**Initializing hardware for the IPMI transport.retval EFI_SUCCESS Hardware was successfully initialized.retval Other An error was returned from PlatformIpmiIoRangeSet.
**/
EFI_STATUS
InitializeIpmiTransportHardware (VOID){EFI_STATUS Status;//// Enable OEM specific southbridge SIO KCS I/O address range 0xCA0 to 0xCAF at here// if the the I/O address range has not been enabled.//Status PlatformIpmiIoRangeSet (PcdGet16 (PcdIpmiIoBaseAddress));DEBUG ((DEBUG_INFO, IPMI: PlatformIpmiIoRangeSet - %r!\n, Status));return Status;
}对于PlatformIpmiIoRangeSet()函数的实现可以暂时不过因为依赖于不同的硬件平台对于x86平台通常是LPC设备一些操作。
当完成PcdIpmiIoBaseAddress基地址之后就可以进行IO操作了对应的寄存器如下 可以看到就4个寄存器如果考虑共用的部分其实就2个寄存器
Status只读寄存器包含了操作过程中的Flag。Command只写寄存器用于写入各类操作这些操作称为“Write Control Codes”。Data_Out只读寄存器用来读取数据。Data_In只写寄存器用来写入数据或者“Read Control Codes”。
这里的“Control Codes”如下 前面的4个是“Write Control Codes”只能写入Status寄存器最后一个是“Read Control Codes”写入Data寄存器前面提到的KSC数据也是写入到Data寄存器的。
Status寄存器的比特说明如下 其中的S0和S1根据组合得到如下的值 得到四种状态。
Status寄存器的代码表示
typedef union {UINT8 RawData;struct {UINT8 Obf : 1;UINT8 Ibf : 1;UINT8 SmAtn : 1;UINT8 CD : 1;UINT8 Oem1 : 1;UINT8 Oem2 : 1;UINT8 State : 2;} Status;
} KCS_STATUS;根据上述的寄存器操作得到BIOS向BMC写数据的流程 对应的代码实现可以在IpmiFeaturePkg\GenericIpmi\Common\GenericIpmi.c找到下面是代码的大致说明
等待IBF0 do {MicroSecondDelay (IPMI_DELAY_UNIT);KcsStatus.RawData IoRead8 (KcsIoBase 1);if ((KcsStatus.RawData 0xFF) || (TimeOut IpmiTimeoutPeriod)) {if ((Status KcsErrorExit (IpmiTimeoutPeriod)) ! EFI_SUCCESS) {return Status;}}TimeOut;} while (KcsStatus.Status.Ibf);写入KCS_WRITE_START并等待IBF0 KcsData KCS_WRITE_START;IoWrite8 ((KcsIoBase 1), KcsData);if ((Status KcsCheckStatus (IpmiTimeoutPeriod, KcsWriteState, Idle)) ! EFI_SUCCESS) {return Status;}开始写入数据等待数据写入完成之后最后写入KCS_WRITE_END for (i 0; i DataSize; i) {if (i (DataSize - 1)) {if ((Status KcsCheckStatus (IpmiTimeoutPeriod, KcsWriteState, Idle)) ! EFI_SUCCESS) {return Status;}KcsData KCS_WRITE_END;IoWrite8 ((KcsIoBase 1), KcsData);}Status KcsCheckStatus (IpmiTimeoutPeriod, KcsWriteState, Idle);if (EFI_ERROR (Status)) {return Status;}IoWrite8 (KcsIoBase, Data[i]);}开始接收数据 while (TRUE) {if ((Status KcsCheckStatus (IpmiTimeoutPeriod, KcsReadState, Idle)) ! EFI_SUCCESS) {return Status;}if (Idle) {*DataSize Count;break;}//// Need to check Data Size -1 to account for array access//if (Count *DataSize) {return EFI_DEVICE_ERROR;}Data[Count] IoRead8 (KcsIoBase);Count;KcsData KCS_READ;IoWrite8 (KcsIoBase, KcsData);}结束数据接收并将数据返回。
以上只是简单的介绍还有一些诸如KcsCheckStatus()的函数没有说明具体可以直接看代码。
IPMI命令介绍
IPMI命令会通过NetFn/Cmd的方式写入到KSC接口中以完成不同的操作这里将列出IPMI规范定义的所以基础操作。在EDK代码中有几个头文件已经定义了部分IPMI命令具体对应的头文件是
#include IndustryStandard/IpmiNetFnChassis.h
#include IndustryStandard/IpmiNetFnBridge.h
#include IndustryStandard/IpmiNetFnSensorEvent.h
#include IndustryStandard/IpmiNetFnApp.h
#include IndustryStandard/IpmiNetFnFirmware.h
#include IndustryStandard/IpmiNetFnStorage.h
#include IndustryStandard/IpmiNetFnTransport.h
#include IndustryStandard/IpmiNetFnGroupExtension.h
#include IndustryStandard/IpmiFruInformationStorage.h需要注意 NetFn都是偶数的。 最后一列的O/M表示的是BMC是否需要实现该命令。 BIOS下的头文件中并没有包含所有IPMI规范中定义的命令所以下面的表中不少命令没有对应的宏。 除了在IPMI规范中定义的命令还可以有自定义的命令这当然是有好处的因为扩展了BIOS和BMC通信的内容但是也存在不同的BIOS和BMC厂商对同一个命令字有不同的实现导致了维护的困难。
