| 5 | 1 | Paul Kocialkowski | h2. Note on shipping libraries |
| 6 | 2 | Paul Kocialkowski | |
| 7 | 3 | Paul Kocialkowski | *Note that we don't ship any proprietary binary, library or firmware.* |
| 8 | *First because our goal is to reach a 100% free Android distribution and also because sometimes, these are not even distributables.* |

| 10 | h2. Libraries |
||
| 11 | |||
| 12 | 1 | Paul Kocialkowski | ||Library location||Function||Can be replaced or avoided?|| |
| 13 | ||/system/lib/libsecril-client.so|| client to Samsung's non-free RIL || probably useless when we use another RIL (like a free replacement) || |
||
| 14 | ||/system/vendor/bin/gpsd|| GPS daemon || has to be replaced to have working GPS || |
||
| 15 | 2 | Paul Kocialkowski | ||/system/vendor/bin/pvrsrvinit|| [[PowerVR]] server initializer, 3d-related || can be avoided || |
| 16 | ||/system/vendor/lib/egl/libEGL_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || |
||
| 17 | ||/system/vendor/lib/egl/libGLESv1_CM_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || |
||
| 18 | ||/system/vendor/lib/egl/libGLESv2_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || |
||
| 19 | 1 | Paul Kocialkowski | ||/system/vendor/lib/hw/gps.s5pc110.so|| GPS lib || has to be replaced to have working GPS || |
| 20 | ||/system/vendor/lib/hw/gralloc.s5pc110.so|| gralloc lib || cannot be avoided but was replaced by a (free) modified version of AOSP's gralloc || |
||
| 21 | ||/system/vendor/lib/libakm.so|| accelerometer + compass || can be avoided but a free replacement (libakm_free) already works with the accelerometer and the magnetic field (compass) will be supported soon || |
||
| 22 | ||/system/vendor/lib/libglslcompiler.so|| ? seems graphics-related || can be avoided || |
||
| 23 | ||/system/vendor/lib/libIMGegl.so|| ? seems graphics-related || can be avoided || |
||
| 24 | ||/system/vendor/lib/libpvr2d.so|| ? seems graphics-related || can be avoided || |
||
| 25 | ||/system/vendor/lib/libpvrANDROID_WSEGL.so|| ? seems graphics-related || can be avoided || |
||
| 26 | ||/system/vendor/lib/libPVRScopeServices.so|| ? seems graphics-related || can be avoided || |
||
| 27 | ||/system/vendor/lib/libsec-ril.so|| Samsung's RIL || has to be replaced to have working telephony and SMS (and data too) || |
||
| 28 | ||/system/vendor/lib/libsrv_init.so|| ? || can be avoided || |

||
| 34 | |||
| 35 | 1 | Paul Kocialkowski | ||File location||Function|| what depend on it || |
| 36 | ||/system/vendor/etc/gps.xml|| gps configuration file || GPS. A (free) rewrite of this would probably conclude to producing almost the same file. || |
