* 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

h4. Source code
28 88 Denis 'GNUtoo' Carikli
29 46 Denis 'GNUtoo' Carikli
First get the source code:
30 1 Denis 'GNUtoo' Carikli
<pre>
31 46 Denis 'GNUtoo' Carikli
$ repo init -u git://git.putti.eu/aosp/manifest_i9305.git -b android-9.0.0
32 1 Denis 'GNUtoo' Carikli
</pre>
33 88 Denis 'GNUtoo' Carikli
34 100 Denis 'GNUtoo' Carikli
h4. For Trisquel8
35 45 Denis 'GNUtoo' Carikli
<pre>
36 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
37
</pre>
38
39 100 Denis 'GNUtoo' Carikli
h4. Building it
40 88 Denis 'GNUtoo' Carikli
41
Once this is done, see the device/putti/i9305/README.md for the build instructions.
42
43 100 Denis 'GNUtoo' Carikli
h4. Trisquel 8 LXC
44 88 Denis 'GNUtoo' Carikli
45
If you use Parabola, you may be interested in running Trisquel 8 in LXC.
46
47
To do that first debootstrap a Trisquel 8 rootfs. 
48
49
Parabola's debootstrap does support Trisquel 8 and its manual has an example on how to do that:
50
<pre>
51
$ man debootstrap
52
[...]
53
# debootstrap flidas flidas-root http://archive.trisquel.info/trisquel
54
</pre>
55
56
Then you can use virt-manager to setup the LXC instance.
57
58 89 Denis 'GNUtoo' Carikli
The advantages of this solution are that:
59 88 Denis 'GNUtoo' Carikli
* The LXC guest and host shares their resources (CPU, RAM) with almost no penalty
60
* Trisquel 8 is not a rolling release distribution
61
62
The disadvantage of this solution are that:
63
* you need to configure again the Trisquel 8 LXC instance (vimrc, sshd_config, etc)
64 1 Denis 'GNUtoo' Carikli
* It's more complicated to setup
65 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
66 48 Denis 'GNUtoo' Carikli

h4. Status with LineageOS 16
72
73 115 Denis 'GNUtoo' Carikli
For now the focus is on building the AOSP9 on top of LineageOS, nothing is usable or even buildable yet.

First month of full time equivalent work:
112 51 Denis 'GNUtoo' Carikli
113 74 Denis 'GNUtoo' Carikli
|_. Task |_. Time estimation |_. Comments |
114 81 Denis 'GNUtoo' Carikli
| -boot a device under AOSP9- | DONE | Only boots with graphics, not much more |
115
| -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- 
116 57 Denis 'GNUtoo' Carikli
Builds under Trisquel8|
117
| * port the changes from AOSP9 to LineageOS 16
118 59 Denis 'GNUtoo' Carikli
* cleanup the code
119
* build the kernel from the Android build system
120 73 Denis 'GNUtoo' Carikli
* make sure it builds with an FSDG compliant distribution
121
* document the build procedure | 21h | |

127 1 Denis 'GNUtoo' Carikli
| port and cleanup the the Galaxy SIII (i9300) "modem":https://github.com/fourkbomb/linux/tree/modem Linux driver from 4.16 to 5.0 | 70h | |
128 93 Denis 'GNUtoo' Carikli
|_. Total |_. 147h | ~1 month |
129 1 Denis 'GNUtoo' Carikli
130 95 Denis 'GNUtoo' Carikli
Second month of full time equivalent work:
131
| * port  libsamsung-ril and libsamsung-ipc to Android 9
132 75 Denis 'GNUtoo' Carikli
* 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 |
133
|_. Total |_. 157h | ~1 month |

136 75 Denis 'GNUtoo' Carikli
|_. Task |_. Time estimation |_. Comments |
137 57 Denis 'GNUtoo' Carikli
| port the sensors libraries and other device specific libraries | 70h | |
138 77 Denis 'GNUtoo' Carikli
| add support for Audio | 70h | Might be way faster, depending on what Android 9 uses |
139 76 Denis 'GNUtoo' Carikli
| add support for the Galaxy SIII (i9300) and factorize the code with i9305 | 14h | |
140
|_. Total |_. 154h | ~1 month |

144 96 Denis 'GNUtoo' Carikli
| add internal WiFi support and validate the functionality | 6h | |
145 74 Denis 'GNUtoo' Carikli
| add external WiFi dongles support | 20h | External dongles support might be tricky |
146 71 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.
147
We also created generic instructions but they tend to be harder to follow[1] than the device specific ones.
148 1 Denis 'GNUtoo' Carikli
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. |
