}
return 0;
}是从version判断的，version又是从deviceName来的，看log deviceName格式是3303:09-02 01:58:38.540 15587 15587 I camera_hidl_hal_test: Camera Id[0] is [email protected]/legacy/0

return deviceName;
}在看上面addDeviceNames的逻辑 mModule->isOpenLegacyDefined() 有定义OpenLegacy的话 和 mModule->openLegacy 打开成功的话会使用CAMERA_DEVICE_API_VERSION_1_0
hardware/interfaces/camera/common/1.0/default/CameraModule.cpp
bool CameraModule::isOpenLegacyDefined() const {
if (getModuleApiVersion() < CAMERA_MODULE_API_VERSION_2_3) {
return false;
}
return mModule->open_legacy != NULL;
}
int CameraModule::openLegacy(
const char* id, uint32_t halVersion, struct hw_device_t** device) {
int res;
ATRACE_BEGIN("camera_module->open_legacy");
res = mModule->open_legacy(&mModule->common, id, halVersion, device);
ATRACE_END();
return res;
}查找open_legacy
在hardware/qcom/camera/QCamera2/QCamera2Hal.cpp 有这么个定义配置
// Camera dependencies
#include "QCamera2Factory.h"

static hw_module_t camera_common = {
.tag = HARDWARE_MODULE_TAG,
.module_api_version = CAMERA_MODULE_API_VERSION_2_4,
.hal_api_version = HARDWARE_HAL_API_VERSION,
.id = CAMERA_HARDWARE_MODULE_ID,
.name = "QCamera Module",
.author = "Qualcomm Innovation Center Inc",
.methods = &qcamera::QCamera2Factory::mModuleMethods,
.dso = NULL,
.reserved = {0}
};
camera_module_t HAL_MODULE_INFO_SYM = {

.reserved = {0}
};
needHAL1Support
hardware/qcom/camera/QCamera2/util/QCameraCommon.cpp
/*===========================================================================
* FUNCTION : needHAL1Support

*

* FALSE -- Only HAL3 supported target.
*==========================================================================*/
bool QCameraCommon::needHAL1Support()
{
char prop[PROPERTY_VALUE_MAX];
memset(prop, 0, PROPERTY_VALUE_MAX);
property_get("persist.vendor.camera.hal1.enable",prop,"");
if(0 < strlen(prop))
{
return (atoi(prop) == 1);
}
#ifdef SUPPORT_ONLY_HAL3
LOGI("ONLY HAL3 SUPPORTED");
return FALSE;
#else
// HAL1/HAL3 is supported
LOGI("HAL1/HAL3 IS SUPPORTED");
return TRUE;
#endif
#ifndef HAS_LOW_RAM
// QM215, QM2150 non-GO supports only HAL3
if ((is_target_QM215() || is_target_QM2150())) {
LOGI("ONLY HAL3 SUPPORTED");
return FALSE;
}
#else
// HAL1/HAL3 is supported
LOGI("HAL1/HAL3 IS SUPPORTED");
return TRUE;
#endif
}到此就比较明了了，解决方法有以下几个可行
1.设置 prop persist.vendor.camera.hal1.enable = 0 关闭hal1
2.定义SUPPORT_ONLY_HAL3 仅允许使用hal3
3.修改QCamera2Hal.cpp 将 “.open_legacy = (qcamera::QCameraCommon::needHAL1Support()) ? qcamera::QCamera2Factory::open_legacy : NULL”, 直接赋值 NULL “.open_legacy = NULL”
其中 第二点SUPPORT_ONLY_HAL3 修改文件 hardware/qcom/camera/QCamera2/Android.mk
修改下满足条件即可
ifneq (,$(filter $(TRINKET) msm8937_32go-userdebug, $(TARGET_BOARD_PLATFORM)))
LOCAL_CFLAGS += -DSUPPORT_ONLY_HAL3
