两个Android 版本进程的区别

主要是从Android O(8)开始引入了HIDL， hal层的服务会以独立进程的形式存在，framework和hal层之间通过hw binder的方式进行同行。所以上图 android P(9)中多出了如下hal层的进程：

system 3187 1 6772 2888 binder_thread_read 0 S android.hidl.allocator@1.0-service audioserver 3188 1 49932 13972 binder_thread_read 0 S android.hardware.audio@2.0-service bluetooth 3189 1 11172 3080 binder_thread_read 0 S android.hardware.bluetooth@1.0-service cameraserver 3190 1 16540 3480 binder_thread_read 0 S android.hardware.camera.provider@2.4-service media 3191 1 9924 3112 binder_thread_read 0 S android.hardware.cas@1.0-service system 3193 1 9708 3100 binder_thread_read 0 S android.hardware.configstore@1.1-service media 3195 1 11068 3172 binder_thread_read 0 S android.hardware.drm@1.0-service media 3196 1 10916 2964 binder_thread_read 0 S android.hardware.drm@1.1-service.clearkey media 3197 1 13528 3112 binder_thread_read 0 S android.hardware.drm@1.1-service.widevine system 3198 1 8320 3064 binder_thread_read 0 S android.hardware.gatekeeper@1.0-service system 3199 1 15492 5588 binder_thread_read 0 S android.hardware.graphics.allocator@2.0-service system 3200 1 71048 6320 binder_thread_read 0 S android.hardware.graphics.composer@2.2-service system 3201 1 7636 3256 SyS_epoll_wait 0 S android.hardware.health@2.0-service system 3202 1 7500 3080 binder_thread_read 0 S android.hardware.light@2.0-service system 3203 1 7528 3220 binder_thread_read 0 S android.hardware.memtrack@1.0-service system 3204 1 7692 3184 binder_thread_read 0 S android.hardware.power@1.0-service system 3205 1 7540 3084 binder_thread_read 0 S android.hardware.thermal@1.0-service system 3206 1 7752 2944 binder_thread_read 0 S android.hardware.tv.cec@1.0-service system 3207 1 10744 3844 binder_thread_read 0 S android.hardware.tv.input@1.0-service system 3209 1 8464 2968 binder_thread_read 0 S android.hardware.usb@1.0-service wifi 3212 1 10396 3604 binder_thread_read 0 S android.hardware.wifi@1.0-service system 3093 1 8644 4024 binder_thread_read 0 S hwservicemanager system 3094 1 6424 2548 binder_thread_read 0 S vndservicemanager

这些进程是在init 启动hal class类型的服务，调用各个rc文件中，比如说camera provider是在这里启动的。8.0以前的版本，hal层的功能是运行在cameraserver进程(framework中 camera service 所在的进程 )

hardware/hardware/interfaces/camera/provider/2.4/default ((7792daf...)) $ cat android.hardware.camera.provider\@2.4-service.rc service vendor.camera-provider-2-4 /vendor/bin/hw/android.hardware.camera.provider@2.4-service class hal user cameraserver group audio camera input drmrpc ioprio rt 4 capabilities SYS_NICE writepid /dev/cpuset/camera-daemon/tasks /dev/stune/top-app/tasks

值得注意的是，这里还多出了hwservicemanager 和 vndservicemanager。framework的服务管理是通过servicemanager，而Android O之后，设备节点多了/dev/hwbinder, /dev/vndbinder. 而hwservicemanager 用于hal层的服务管理，framework层的服务通过hwservicemanager 查询hal层的服务。而hal层的服务（vendor提供的）之间，通过 vndservicemanager来管理。

HIDL ，直通式HAL（ Passthrough 模式）和 绑定式 HAL （Binderized模式）后续会补充上。
