| 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 /vendor/lib/hw/ and have a well defined naming | 
 | convention: | 
 |  | 
 |     /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.product.board>.so | 
 |     /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.board.platform>.so | 
 |     /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.arch>.so | 
 |     /vendor/lib/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/. |
