* The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries:
10 99 Denis 'GNUtoo' Carikli
** The device boots until the lock screen
11 98 Denis 'GNUtoo' Carikli
** The graphics work but are really slow as they have not been optimized
12 49 Denis 'GNUtoo' Carikli
** Sometime the display content is corrupted
13 1 Denis 'GNUtoo' Carikli
** The touchscreen works
14 100 Denis 'GNUtoo' Carikli
* 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

25 88 Denis 'GNUtoo' Carikli
26 46 Denis 'GNUtoo' Carikli
First get the source code:
27 1 Denis 'GNUtoo' Carikli
<pre>
28 46 Denis 'GNUtoo' Carikli
$ repo init -u git://git.putti.eu/aosp/manifest_i9305.git -b android-9.0.0

h4. For Trisquel8
32 45 Denis 'GNUtoo' Carikli
<pre>
33 1 Denis 'GNUtoo' Carikli
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
34
</pre>
35
36 100 Denis 'GNUtoo' Carikli
h4. Building it
37 88 Denis 'GNUtoo' Carikli
38
Once this is done, see the device/putti/i9305/README.md for the build instructions.

h4. Trisquel 8 LXC
41 88 Denis 'GNUtoo' Carikli
42
If you use Parabola, you may be interested in running Trisquel 8 in LXC.
43
44
To do that first debootstrap a Trisquel 8 rootfs. 
45
46
Parabola's debootstrap does support Trisquel 8 and its manual has an example on how to do that:
47
<pre>
48
$ man debootstrap
49
[...]
50
# debootstrap flidas flidas-root http://archive.trisquel.info/trisquel
51
</pre>
52
53
Then you can use virt-manager to setup the LXC instance.
54
55 89 Denis 'GNUtoo' Carikli
The advantages of this solution are that:
56 88 Denis 'GNUtoo' Carikli
* The LXC guest and host shares their resources (CPU, RAM) with almost no penalty
57
* Trisquel 8 is not a rolling release distribution
58
59
The disadvantage of this solution are that:
60
* you need to configure again the Trisquel 8 LXC instance (vimrc, sshd_config, etc)
61 1 Denis 'GNUtoo' Carikli
* It's more complicated to setup
62 90 Denis 'GNUtoo' Carikli
* The Android build system output a warning message about not being able to use namespaces which may become mandatory in newer Android versions

|_. Task |_. Time estimation |_. Comments |
97 74 Denis 'GNUtoo' Carikli
| -boot a device under AOSP9- | DONE | Only boots with graphics, not much more |
98 81 Denis 'GNUtoo' Carikli
| -build it under a "FSDG compliant distribution":https://www.gnu.org/distros/free-distros.html like Trisquel8- | -7h- DONE | -WIP for AOSP, 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- 
99
Builds under Trisquel8|
100 57 Denis 'GNUtoo' Carikli
| * port the changes from AOSP9 to LineageOS 16
101
* cleanup the code
102 59 Denis 'GNUtoo' Carikli
* build the kernel from the Android build system
103
* make sure it builds with an FSDG compliant distribution

Second month of full time equivalent work:
114 95 Denis 'GNUtoo' Carikli
| * port  libsamsung-ril and libsamsung-ipc to Android 9
115
* Make the modem driver and libsamsung-ipc work together | 157h | libsamsung-ipc should be trivial, libsamsung-ril probably needs to be heavily adapted to Trebble or the new RIL interfaces |
116 75 Denis 'GNUtoo' Carikli
|_. Total |_. 157h | ~1 month |

120 75 Denis 'GNUtoo' Carikli

121 57 Denis 'GNUtoo' Carikli
| add support for Audio | 70h | Might be way faster, depending on what Android 9 uses |
122 77 Denis 'GNUtoo' Carikli
| add support for the Galaxy SIII (i9300) and factorize the code with i9305 | 14h | |
123 76 Denis 'GNUtoo' Carikli

126 67 Denis 'GNUtoo' Carikli

127 71 Denis 'GNUtoo' Carikli
| add internal WiFi support and validate the functionality | 6h | |
128 96 Denis 'GNUtoo' Carikli
| add external WiFi dongles support | 20h | External dongles support might be tricky |
129 74 Denis 'GNUtoo' Carikli
| create new install and upgrade instructions | 35h | Our current install instructions don't scale as we have one copy for each device.
130 71 Denis 'GNUtoo' Carikli
We also created generic instructions but they tend to be harder to follow[1] than the device specific ones.
131
This will be made in a modular format (for instance in LaTeX) that enables to generate per device install instructions without requiring to have multiples copy of the same text. The instructions will need to be able to be modified and compiled on an FSDG compliant distribution. |
