1 Default (and possibly architecture dependents) HAL modules go here. 2 3 4 libhardware.so eventually should contain *just* the HAL hub 5 (hardware.c), everything in it should be rewritten as modules. 6 7 Modules are .so in /vendor/lib/hw/ and have a well defined naming 8 convention: 9 10 /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.product.board>.so 11 /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.board.platform>.so 12 /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.<ro.arch>.so 13 /vendor/lib/hw/<*_HARDWARE_MODULE_ID>.default.so 14 15 They also have a well defined interface which lives in include/hardware/. 16 17 A module can have several variants: "default", "arch" and "board", and they're 18 loaded in the "board", "arch" and "default" order. 19 The source code for the "board" variant, usually lives under partners/... 20 21 The source code for "default" and "arch" would usually 22 live under hardware/modules/. 23 24
