Revision 53 (Denis 'GNUtoo' Carikli, 03/28/2019 01:52 PM) → Revision 54/287 (Denis 'GNUtoo' Carikli, 03/28/2019 01:56 PM)

h1. Porting Replicant to Android 9 

 h2. Status 

 * The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries. Not much has been validated beside that. 
 * The kernel used is based on Linux 5.0-rc6 and has ~150 Android specific patches on top and some patches for the Galaxy SIII 4G (i9305) on top 

 h2. Repositories and changes 
 
 * git://git.putti.eu/aosp/manifest_i9305.git 
 * git://git.putti.eu/aosp/kernel_i9305.git 
 * git://git.putti.eu/aosp/device_i9305.git 

 h2. Building 

 First get the source code: 
 <pre> 
 $ repo init -u git://git.putti.eu/aosp/manifest_i9305.git -b android-9.0.0 
 </pre> 

 For Trisquel8 (WIP): 
 <pre> 
 sudo apt-get install git-core gnupg flex bison gperf build-essential zip curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386 lib32ncurses5-dev x11proto-core-dev libx11-dev lib32z-dev libgl1-mesa-dev libxml2-utils xsltproc unzip bc python-mako 
 </pre> 

 Then see the device/putti/i9305/README.md for the build instructions. 

 h2. TODO 

 |_. Task |_. Time estimation |_. Comments | 
 | -Boot a device under AOSP9- | DONE | Only boots with graphics, not much more | 
 | Build it under a "FSDG compliant distribution":https://www.gnu.org/distros/free-distros.html like Trisquel8 | 8h | It's difficult to do precise time estimations as it could work out of the box or require one full time month of work depending on how much issues are encountered | 
 | Port the changes from AOSP9 to LineageOS 16 | | | 
 | Find and remove proprietary software in LineageOS 16 | | | 
 | Find and remove privacy issues in LineageOS 16 | | | 
 | Cleanup the device code, build the kernel from within Replicant | | | 
 | Add support for Audio | | | 
 | Port the sensors libraries and other device specific libraries | | | 
 | Add support for the i9300 and factorize the code with i9305 | | | 
 | Add support for the i9300 modem, touch keys, and flash led | | | 
 | Add internal WiFi and external WiFi dongles support | | | 
 | Make the modem driver and libsamsung-ipc work together | | | 
 | Port libsamsung-ipc and libsamsung-ril to Android 9| | | 
 | Rebrand LineageOS as Replicant | | | 
 | Create a recovery | | | 
 | Create install and upgrade instructions | | | 
 | Reduce the attack surface | | | 
 | Add in-system upgrades | | 

 Add support for smartphones that were supported in Replicant 4.2 and 6.0 if they meet the [[HardwareRequirements]]: 
 |_. Device |_. Time estimation |_. Comments | 
 | Galaxy Note II (N7100) | |/2. | Similar to the Galaxy SIII (I9300) |  
 | Galaxy Note 8.0 (N5100) and 8.0 WiFi (N5110)| (N7000) | | | 
 | Galaxy S II (i9100) Nexus (I9250) | | linux: devboard dts upstream? unknown status | 
 | Galaxy Note (N7000) S II (i9100) | | unknown linux upstream status | 
 | Galaxy Nexus (I9250) Note 8.0 (N5100) and 8.0 WiFi (N5110)| | |/2. OMAP4, no dts upsrteam |
