h4. Getting lastest changes
67
68 201 Kurtis Hanna
* The repositories are being constantly modified with git push --force as we are trying things out, and don't want to make the commits history look too dirty, so be sure to backup your local changes.
69 142 Denis 'GNUtoo' Carikli
* Sometimes the manifest repository is also modified with git push --force. In that case the following commands will loose all the work you did locally but will make the repository consistent with upstream repositories again:
70
<pre>
71
$ rm -rf .repo/manifests/ # This enables me to force push and rebase the manifest repository as well
72 198 Denis 'GNUtoo' Carikli
$ repo init -u https://git.replicant.us/replicant-9/manifest.git -b replicant-9
73 142 Denis 'GNUtoo' Carikli
$ repo sync --force-sync
74
</pre>
75
* The following command might also be necessary to make the state consistent with upstream repositories again, when the manifest history wasn't rewritten, but it will also loose all the work you did locally: 
76
<pre>
77
$ repo sync --force-sync
78 136 Denis 'GNUtoo' Carikli
</pre>
79
80 138 Denis 'GNUtoo' Carikli
h4. Install the images
81
82
<pre>
83 165 dl lud
$ sudo heimdall flash --BOOT out/target/product/i9305/obj/PACKAGING/target_files_intermediates/lineage_i9305-target_files-eng.replicant/IMAGES/boot.img --USERDATA out/target/product/i9305/obj/PACKAGING/target_files_intermediates/lineage_i9305-target_files-eng.replicant/IMAGES/userdata.img --SYSTEM out/target/product/i9305/obj/PACKAGING/target_files_intermediates/lineage_i9305-target_files-eng.replicant/IMAGES/system.img 
84 138 Denis 'GNUtoo' Carikli
</pre>
85
86
h4. Get adb
87
88 147 Denis 'GNUtoo' Carikli
As the device IDs are the ones given by the Linux kernel, they are not in the adb udev rules, so for now it requires to run adb as root:
89 138 Denis 'GNUtoo' Carikli
<pre>
90 1 Denis 'GNUtoo' Carikli
$ sudo adb shell
91
* daemon not running; starting now at tcp:5037
92
* daemon started successfully
93
i9305:/ #                                 
94
$ sudo adb kill-server
95
$ adb shell
96
* daemon not running; starting now at tcp:5037
97
* daemon started successfully
98
error: no devices/emulators found
99
</pre>
100
So make sure to kill the adb-server and run it as root:
101
<pre>
102
$ adb kill-server
103
$ sudo adb shell
104
* daemon not running; starting now at tcp:5037
105
* daemon started successfully
106
i9305:/ # 
107
</pre>
108
109
h4. Booting
110
111
At some point during boot, the device goes into suspend, so you will need to press some buttons like the power or volume button to make the boot continue until the graphical interface.
112
113
You can also follow the boot progress with adb:
114
<pre>
115
adb logcat
116
adb logcat -b main
117
</pre>
118
119
Note that the device can go into suspend at any time, so adb might be interrupted. That looks like that:
120
First you get a shell
121
<pre>
122
$ sudo adb shell
123
i9305:/ #
124
</pre>
125
126
Then the connection is interrupted:
127
<pre>
128
$ adb shell
129
i9305:/ # [randomdev@fullyfreelaptop ]$                                                                                                     
130
</pre>
131
132
The effect with adb logcat is similar.
133
134
h3. cleanups to be done
135
136
* Make adb work as user by using the right USB IDs, and make userspace do the USB setup.
137
* -Make the kernel not use hardcoded CMDLINE_FORCE- Not possible unless the bootloader is changed or Linux is very heavily patched.
138
* Make the kernel not use hardcoded partitions if possible (though we use system as root)
139
* Make a clean Gatekeeper HAL module implementation instead of using the same hack than goldfish
140
* look at "init.rc":https://android.googlesource.com/platform/system/core/+/master/init/README.md documentation to see if init.rc can be overriden clearly with the override statement to see if it's possible to keep the serial console patch for -eng
141
142
h3. Using SwiftShader instead of Mesa3D llvmpipe for software rendering
143
144
To use SwifShader you need a kernel that supports UDIV/SDIV emulation, you can checkout the branch GNUtoo/udiv-emulation for kernel/replicant/linux. After doing that that run the following commands to use SwiftShader:
145
146
<pre>
147
$ adb remount
148
$ adb shell
149
i9305:/ # rm vendor/lib/egl/libGLES_mesa.so # or move it somewhere safe meanwhile you test SwiftShader
150
i9305:/ # nano system/build.prop # set ro.hardware.hwcomposer=ranchu and ro.hardware.gralloc=default
151
$ adb reboot
152
</pre>

h2. AOSP 9
155
156
h3. Status with AOSP 9
157
158
* The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries:
159
** The device boots until the lock screen
160
** The graphics work but are really slow as they have not been optimized
161
** Sometime the display content is corrupted
162
** The touchscreen works
163
* 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
164

h3. Building AOSP version
175
176
h4. Source code
177
178
First get the source code:
179
<pre>
180
$ repo init -u git://git.putti.eu/aosp/manifest_i9305.git -b android-9.0.0
181
</pre>
182
183
h4. For Trisquel 8
184
185
<pre>
186
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 gcc-5-arm-linux-gnueabi
187
</pre>
188
189
h4. Building it
190
191
Once this is done, see the device/putti/i9305/README.md for the build instructions.
192
193
h4. Trisquel 8 LXC
194
195
If you use Parabola, you may be interested in running Trisquel 8 in LXC.
196
197
To do that first debootstrap a Trisquel 8 rootfs. 
198
199
Parabola's debootstrap does support Trisquel 8 and its manual has an example on how to do that:
200
<pre>
201
$ man debootstrap
202
[...]
203
# debootstrap flidas flidas-root http://archive.trisquel.info/trisquel
204
</pre>
205
206
Then you can use virt-manager to setup the LXC instance.
207
208
The advantages of this solution are that:
209
* The LXC guest and host shares their resources (CPU, RAM) with almost no penalty
210
* Trisquel 8 is not a rolling release distribution
211
212
The disadvantage of this solution are that:
213
* you need to configure again the Trisquel 8 LXC instance (vimrc, sshd_config, etc)
214
* It's more complicated to setup
215
* The Android build system output a warning message about not being able to use namespaces which may become mandatory in newer Android versions

228
| -7h- DONE | -build it under a "FSDG compliant distribution":https://www.gnu.org/distros/free-distros.html like Trisquel8- | -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- 
229 59 Denis 'GNUtoo' Carikli
Builds under Trisquel8|
230 144 Joonas Kylmälä
| 21h | * -port the changes from AOSP9 to LineageOS 16-

243
| 70h | port and cleanup the the Galaxy SIII (i9300) "modem":https://github.com/fourkbomb/linux/tree/modem Linux driver from 4.16 to 5.0| |
244
|_\3. Total: 147h (~1 month) |
245 95 Denis 'GNUtoo' Carikli
246 75 Denis 'GNUtoo' Carikli
Second month of full time equivalent work:
247 1 Denis 'GNUtoo' Carikli
| * port  libsamsung-ril and libsamsung-ipc to Android 9
248
* 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-
249 160 Denis 'GNUtoo' Carikli
-libsamsung-ipc and samsung-ril were fixed to compile on Android 9.-
250 158 Denis 'GNUtoo' Carikli
-The code was not yet tested at runtime.-
251 1 Denis 'GNUtoo' Carikli
-It also probably still need to be adapted to trebble or the new RIL interfaces to be more substainable.-
252 160 Denis 'GNUtoo' Carikli
Status:
253
* The code has been updated to work without a wrapper on Android 9, but some cleanups are needed in all the modem related components.
254
* The modem doesn't work yet on Replicant 9 but some of the initialization already works.

365
It needs to be adapted to the upstream kernel and not to use proprietary libraries.

| -create new- update the install and upgrade instructions | -35h- | -Our current install instructions don't scale as we have one copy for each device.-
374
-We also created generic instructions but they tend to be harder to follow[1] than the device specific ones.-
375
-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.-
376
-The instructions will need to be able to be modified and compiled on an FSDG compliant distribution.- |
