| Default (and possibly architecture dependents) HAL modules go here. |
| |
| |
| libhardware.so eventually should contain *just* the HAL hub |
| (hardware.c), everything in it should be rewritten as modules. |
| |
| Modules are .so in /system/libs/hw/ and have a well defined naming |
| convention: |
| |
| /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.product.board>.so |
| /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.board.platform>.so |
| /system/libs/hw/<*_HARDWARE_MODULE_ID>.<ro.arch>.so |
| /system/libs/hw/<*_HARDWARE_MODULE_ID>.default.so |
| |
| They also have a well defined interface which lives in include/hardware/. |
| |
| A module can have several variants: "default", "arch" and "board", and they're |
| loaded in the "board", "arch" and "default" order. |
| The source code for the "board" variant, usually lives under partners/... |
| |
| The source code for "default" and "arch" would usually |
| live under hardware/modules/. |
