1,主备状态是否ok。
看里面的0-3工作在Master(master Active), 4-7 工作在Master(wait master),主控0-3,备控4-7.
current postion说明:
typedef enum
{
VEGA_HMUX_SWITCH_TO_MASTER = 0,
VEGA_HMUX_SWITCH_TO_SLAVE = 1,
VEGA_HMUX_SWITCH_TO_PATTERN = 2,
VEGA_HMUX_SWITCH_TO_SM,
VEGA_HMUX_SWITCH_TO_MASTER_FORCE,
VEGA_HMUX_SWITCH_TO_SLAVE_FORCE,
VEGA_HMUX_SWITCH_TO_PATTERN_FORCE,
}hmux_switch;
FSM_state说明:
2,line测和host测对应关系:
3,单主控和双主控的区别:
retimer状态:(和模块有关,lrx信息是模块这边产生的相关信号)
