h1. Nexus S Proprietary This is the list of the proprietary libraries, binaries and firmwares shipped on the Nexus S and the status of their replacement. h2. Note on shipping libraries *Note <pre> <code class="div"> Note that we don't ship any proprietary binary, library daemon,library,configuration file or firmware.* *First because our firmware. Because we don't want to(our goal is to reach make a 100% free Android distribution Distribution) and also because sometimes, these we can't(none of theses are redistributables, even the firmwares are not even distributables.* redistributable). </code></pre> h2. Libraries ||Library location||Function||Can be replaced or avoided?|| ||/system/lib/libsecril-client.so|| client to Samsung's non-free RIL || probably useless when we use another RIL (like a free replacement) || ||/system/vendor/bin/gpsd|| GPS daemon || has to be replaced to have working GPS || ||/system/vendor/bin/pvrsrvinit|| [[PowerVR]] server initializer, 3d-related || can be avoided || ||/system/vendor/lib/egl/libEGL_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || ||/system/vendor/lib/egl/libGLESv1_CM_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || ||/system/vendor/lib/egl/libGLESv2_POWERVR_SGX540_120.so|| [[PowerVR]] 3d lib || can be avoided || ||/system/vendor/lib/hw/gps.s5pc110.so|| GPS lib || has to be replaced to have working GPS || ||/system/vendor/lib/hw/gralloc.s5pc110.so|| gralloc lib || cannot be avoided but was replaced by a (free) modified version of AOSP's gralloc || ||/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 || ||/system/vendor/lib/libglslcompiler.so|| ? seems graphics-related || can be avoided || ||/system/vendor/lib/libIMGegl.so|| ? seems graphics-related || can be avoided || ||/system/vendor/lib/libpvr2d.so|| ? seems graphics-related || can be avoided || ||/system/vendor/lib/libpvrANDROID_WSEGL.so|| ? seems graphics-related || can be avoided || ||/system/vendor/lib/libPVRScopeServices.so|| ? seems graphics-related || can be avoided || ||/system/vendor/lib/libsec-ril.so|| Samsung's RIL || has to be replaced to have working telephony and SMS (and data too) || ||/system/vendor/lib/libsrv_init.so|| ? || can be avoided || ||/system/vendor/lib/libsrv_um.so|| ? || can be avoided || ||/system/vendor/lib/libusc.so|| ? || can be avoided || h2. Configuration files ||File location||Function|| what depend on it || ||/system/vendor/etc/gps.xml|| gps configuration file || GPS. A (free) rewrite of this would probably conclude to producing almost the same file. || h2. Firmwares ||Firmware location||Function|| what depend on it || ||/system/vendor/firmware/fw_bcm4329.bin|| wifi firmware || wifi || ||/system/vendor/firmware/fw_bcm4329_apsta.bin|| wifi AP firmware || wifi access point || ||/system/lib/libpn544_fw.so||NFC firmware||Near Field Communication|| ||/system/vendor/firmware/bcm4329.hcd|| bluetooth firmware || bluetooth || ||/system/vendor/firmware/nvram_net.txt|| wifi-related firmware || wifi || ||/system/vendor/firmware/samsung_mfc_fw.bin|| MFC firmware || Multi Format Codec (hardware video encoding/decoding) || h2.
