6 | 5 | Denis 'GNUtoo' Carikli | h2. General freedom issues on the Galaxy S 3 (I9300): |
7 | |||
8 | 1 | Denis 'GNUtoo' Carikli | * The bootloader is proprietary and signed. |
9 | 9 | Denis 'GNUtoo' Carikli | * Some peripherals do require proprietary firmwares to work, some of which have to be loaded by the system: See the "Missing without non-free firmwares" status in [[ReplicantStatus]]. |
10 | 11 | Denis 'GNUtoo' Carikli | * The bootrom is the first code that is executed, it's stored in a read-only memory: see "freedom-privacy-security-issues":http://www.replicant.us/freedom-privacy-security-issues.php for more details. |
11 | 12 | Denis 'GNUtoo' Carikli | * The hardware is proprietary, and we are not aware if any its schematics is available somewhere on the Internet. |

13 | 5 | Denis 'GNUtoo' Carikli | h2. Modem related: |
14 | 6 | Denis 'GNUtoo' Carikli | |
15 | 5 | Denis 'GNUtoo' Carikli | The modem runs non-free software, which is loaded but not shipped by Replicant. |
16 | * When using flight mode, The main CPU has to ask the modem to power itself off. |
||
17 | 1 | Denis 'GNUtoo' Carikli | * The modem is isolated: |
18 | ** It doesn't use shared memory with the CPU, instead it uses an "HSIC" bus. |
||
19 | 12 | Denis 'GNUtoo' Carikli | ** We are not aware of it being able to access the GPS, but it woulnd't be surprising if it still could (by having a direct connection to it: since no schematics are publically available we have easy no way to check). |
20 | 3 | Denis 'GNUtoo' Carikli | ** It has no access to the other CPU peripherals. |
21 | 7 | Denis 'GNUtoo' Carikli | * "Terminal profile":https://terminal-profile.osmocom.org/decode.php?tp=ffffffff7f1f00dfff00001fa2010a860749000000000000000000000010 |
