Secure Monitor Calls 在ARM体系架构中,处于安全状态下的调用者(Caller)和处于潜在的非安全状态下的被调用者(Calee),需要通过Secure Monitor Call同步异常,进行同步的控制切换。SMC异常是由SMC指令产生,同时,或者被EL3 Monitor进行处理,或者会陷入(trapped)到EL2当中处理。被调用者Callee的处理,通过寄存器的参数传入,进...
This document defines a common calling mechanism to be used with the Secure Monitor Call (SMC) and Hypervisor Call (HVC) instructions in both the Armv7 and Armv8 architectures.

Registers X18-X30 and stack pointers SP_EL0, SP_ELx are callee-saved and must be preserved over the SMC call When SMC64 call is made from AArch64: arguments are passed in registers X0-X6 Results are return in X0-X3 Registers X18-X30 and stack pointers SP_EL0, SP_ELx are callee-...
SMC2.0以“ip##会议号”方式呼叫至SMC3.0的SC来组建级联会议,呼叫失败,级联会场不入会。 处理过程 1、在SMC3.0的SC抓取信令诊断,可以看到,SMC2.0的MCU呼叫过来的时候,SMC3.0的SC直接回了release挂断: 2、在SMC3.0的SC日志内过滤对应的callid,可以看到有报错ERR_BUSINESS_CALL_UP_TO_MAX_CALL_NUM(0x21200101):...
(1)分析协议层日志\scBackupLog\scproxy.log,直接过滤前面信令包call ID,通过TID标示这一次呼叫,查看到协议层收到业务层响应,结果0x21200113 查询错误代表表,表示“被叫不存在” (2)分析业务层日志\scBackupLog\scBusinessLog.log,还是通过call ID过滤,TID标识这一路呼叫。查看到消息已从业务层转给access接入层。
