Android8.0 高通PDAF 调试 – actuator sensitivity

有一说一

遇到的问题点调试过程中发现进不来pdaf流程 log显示如下：

01-01 08:08:54.425  2414  6352 D mm-camera: <STATS_AF ><  LOW> 3994: af_port_handle_module_event: Handle AF module event of type: 0

问题分析：

Review 代码发现逻辑如下：

/* update depth service cal data */
af_port->ds_input.cal_data.eff_focal_length = sensor_info->actuator_info.focal_length;
af_port->ds_input.cal_data.f_num = sensor_info->actuator_info.af_f_num;
af_port->ds_input.cal_data.pixel_size  = sensor_info->actuator_info.af_f_pix;
af_port->ds_input.cal_data.is_pdaf_supported = sensor_update->is_pdaf_supported;
af_port->ds_input.cal_data.actuator_sensitivity = sensor_update->actuator_sensitivity;
if(sensor_update->actuator_sensitivity <= 0) { 

AF_ERR("Depth_Err: actuator sensitivity: %f is invalid",
sensor_update->actuator_sensitivity);
rc = FALSE;
}
if(sensor_update->is_pdaf_supported && FALSE == rc) { 

AF_LOW("Depth_Err: pdaf cal data from sensor supported %d pdaf_ptr %p",
sensor_update->is_pdaf_supported, sensor_update->pdaf_data);
af_port->ds_input.cal_data.is_pdaf_supported = 0;
}

actuator_sensitivity invalid时，无法启用pdaf support 那么这个问题是哪里来的呢？ sensor初始化的时候我们可以发现计算actuator_sensitivity的过程

boolean module_sensor_actuator_init_calibrate(
module_sensor_bundle_info_t *s_bundle)
{ 

/* calcualte actuator sensitivity assuming total_steps is tuned to number of um */
s_bundle->actuator_sensitivity =
(float)af_driver_ptr->actuator_tuned_params.region_params[0].qvalue /
af_driver_ptr->actuator_tuned_params.region_params[0].code_per_step;
}
/* protect the qvalue */
else { 

af_driver_ptr->actuator_tuned_params.region_params[0].qvalue = 1;
}
}

这个时候需要马达的qvuale值，经过对比发现马达驱动没有此设置遂改之

    .actuator_tuned_params =
{ 

.scenario_size =
{ 

2, /* MOVE_NEAR */
3, /* MOVE_FAR */
},
.ringing_scenario =
{ 

/* MOVE_NEAR */
{ 

36,
243,
},
/* MOVE_FAR */
{ 

72,
198,
243,
},
},
.initial_code = 136,
.region_size = 1,
.region_params =
{ 

{ 

.step_bound =
{ 

243, /* Macro step boundary*/
0, /* Infinity step boundary*/
},
.code_per_step = 1,
.qvalue = 1,
},
},
