About how can Android system application use optee client API in the future

[dracular1983]

Hi All,

Currenttly, the treble architecture of Android P, have a lot of restrictions . for example, libary linker, socket between system and vendor .
Once a system service want to use the op-tee client api, it will face the problem.Maybe we can use hidl service to deal with this . But it still will be some problem about sharememory and struction inforation which need to be passed between process.
I notice op-tee is doing some work about the AOSP . Will you have a plan to design a standard hidl interface for the gp client api？

Thanks

Hi,

I'm not sure if treble applies here? Treble defines a standard interface for the hardware/hal (vendor) but the client api lives above the OS framework.

You'd just use JNI to call the api from the apks. See linaro-swg/optee_android_manifest#31 for some discussions about it.
