무조건 binderized. 나머지 벤더에 의해 제공되는 HAL은 모드 Each HAL runs in its own sandbox and is permitted access to only the hardware driver it controls and the permissions granted to the process are limited to the permissions required to do its job. Similarly, the process loses access to hardware drivers and other permissions and capabilities needed by the HALs.

Its a work in These HALs wrap existing HALs and can serve the HAL in binderized and same-process (passthrough) modes. 升级到AndroidO系统的设备可以使用passthrough HALs。 NOTE: Android provides the following HIDL interfaces which will always be in binderized mode: android.frameworks.*, android.system.* , and android.hidl.* (except for android.hidl.memory@1.0 as described below). 这些 HAL 取代了早期 Android 版本中使用的传统 HAL 和旧版 HAL。在绑定式 HAL 中，Android 框架和 HAL 之间通过 Binder 进程间通信 (IPC) 调用进行通信。所有在推出时即搭载了 Android 8.0 或后续版本的设备都必须只支持绑定式 HAL。 Binderized： Google官方翻译成绑定试HAL。 Passthrough：Google官方翻译成直通式HAL。大致框架图如下，对于Android O之前的设备，对应图1，对于从之前的设备升级到O的版本，对应图2、图3.

These HALs replace both conventional and legacy HALs used in earlier versions of Android. In a Binderized HAL, the Android framework and HALs communicate with each other using binder inter-process communication (IPC) calls. A minimal but complete binderized HAL service implementation for Android Q. In transitioning from libhardware HALs to HIDL HALs, the HAL implementation becomes the server and the process calling into the HAL becomes the client. Default implementations can serve both passthrough and binderized HALs, and can change over time: Figure 1. Development progression for legacy HALs.
