The development is moving toward Android 10. 
8
9
The basic features working on Replicant 9 have also been confirmed to work on Replicant 10, but not everything has been tested yet on either version.
10
11
At this point, the Replicant 9 source code is kept to do regression tracking, and the development has moved to Replicant 10.

* 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.
85
* 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:
86
<pre>
87
$ rm -rf .repo/manifests/ # This enables me to force push and rebase the manifest repository as well
88
$ repo init -u https://git.replicant.us/replicant-9/manifest.git -b replicant-10-wip
89
$ repo sync --force-sync
90
</pre>
91
* 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:

102
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:

106
* daemon started successfully

205
206 147 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:
207 138 Denis 'GNUtoo' Carikli
<pre>
208 1 Denis 'GNUtoo' Carikli

209
* daemon not running; starting now at tcp:5037

214
* daemon not running; starting now at tcp:5037
215
* daemon started successfully
216
error: no devices/emulators found
217
</pre>
218
So make sure to kill the adb-server and run it as root:
219
<pre>
220
$ adb kill-server
221
$ sudo adb shell
222
* daemon not running; starting now at tcp:5037

i9305:/ #

</pre>
226
227
h4. Booting
228
229
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.
230
231
You can also follow the boot progress with adb:
232
<pre>
233
adb logcat
234
adb logcat -b main
235
</pre>
236
237
Note that the device can go into suspend at any time, so adb might be interrupted. That looks like that:
238
First you get a shell
239
<pre>
240
$ sudo adb shell
241
i9305:/ #
242
</pre>
243
244
Then the connection is interrupted:
245
<pre>
246
$ adb shell
247
i9305:/ # [randomdev@fullyfreelaptop ]$                                                                                                     
248
</pre>
249
250
The effect with adb logcat is similar.
251
252
h3. cleanups to be done
253
254
* Make adb work as user by using the right USB IDs, and make userspace do the USB setup.
255
* -Make the kernel not use hardcoded CMDLINE_FORCE- Not possible unless the bootloader is changed or Linux is very heavily patched.
256
* Make the kernel not use hardcoded partitions if possible (though we use system as root)
257
* Make a clean Gatekeeper HAL module implementation instead of using the same hack than goldfish
258
* 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
259
260
h3. Using SwiftShader instead of Mesa3D llvmpipe for software rendering
261
262
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:
263
264
<pre>
265
$ adb remount
266
$ adb shell
267
i9305:/ # rm vendor/lib/egl/libGLES_mesa.so # or move it somewhere safe meanwhile you test SwiftShader
268
i9305:/ # nano system/build.prop # set ro.hardware.hwcomposer=ranchu and ro.hardware.gralloc=default
269
$ adb reboot

* The Galaxy SIII 4G (i9305) boots (with graphics hacks) under AOSP9, without having to import nonfree libraries:
277
** The device boots until the lock screen
278
** The graphics work but are really slow as they have not been optimized
279
** Sometime the display content is corrupted
280
** The touchscreen works
281
* 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

305
</pre>
306
307
h4. Building it
308
309
Once this is done, see the device/putti/i9305/README.md for the build instructions.
310
311
h4. Trisquel 8 LXC
312
313
If you use Parabola, you may be interested in running Trisquel 8 in LXC.
314
315
To do that first debootstrap a Trisquel 8 rootfs. 
316
317
Parabola's debootstrap does support Trisquel 8 and its manual has an example on how to do that:
318
<pre>
319
$ man debootstrap
320
[...]
321
# debootstrap flidas flidas-root http://archive.trisquel.info/trisquel
322
</pre>
323
324
Then you can use virt-manager to setup the LXC instance.
325
326
The advantages of this solution are that:
327
* The LXC guest and host shares their resources (CPU, RAM) with almost no penalty
328
* Trisquel 8 is not a rolling release distribution
329
330
The disadvantage of this solution are that:
331
* you need to configure again the Trisquel 8 LXC instance (vimrc, sshd_config, etc)
332
* It's more complicated to setup
333
* The Android build system output a warning message about not being able to use namespaces which may become mandatory in newer Android versions

354
* Ported to Replicant 9 using a wrapper for the API >=12 in libsamsung-ril source code that needs to be removed
355
* Tested under Replicant 9 without up to date libsamsung-ipc (no modem init)
356
* Tested and validated under Replicant 6 (doesn't break telephony)
357
358
h3. Modem status TODO
359
360 227 Denis 'GNUtoo' Carikli
* Implement the missing part to shut down the modem, close the interfaces and such, in order to need to reboot after each test.
361
* Continue to clean up the libsamsung-ipc and libsamsung-ril patches, test the patches in Replicant 6 when applicable, and merge them in the upstream repositories.
362
* Convert the firmware loading driver to the upstream API and then adapt libsamsung-ipc for that. This should also benefit other devices like the Galaxy SIII 4G, and the Galaxy Note II 4G which probably don't need much more to get their modem supported by upstream Linux.
363
* Cleanup and convert the rest of the drivers to look like the ones for the Nokia N900 and adapt the userspace in libsamsung-ipc, and merge libsamsung-ipc support for that once the kernel API is stable.
364
* Test the code under Replicant 9 when the graphics status will enable to have decent enough speed to do some testing through human interaction.

| -port the sensors libraries and other device specific libraries-
398
Look which sensor libraries can be used | 70h | Already done by the unofficial LineageOS port of the Galaxy SIII (i9300), needs testing |
399 255 Denis 'GNUtoo' Carikli
| add support for Audio with the upstream kernel driver | 70h | Might be way faster, depending on what Android 9 uses

401 212 Denis 'GNUtoo' Carikli
| -add partial (no modem) support for the Galaxy SIII 4G (i9305) and- factorize the code with i9300 | 14h | * The source code on which the work was based changed from AOSP to an unofficial LineageOS port to a port of i9305 support for AOSP by Joonas to the official LineageOS so it's now supported by default
402
* The work to factorize the code between the i9300 and i9305 still need to be done |

| -create new- update the install and upgrade instructions | -35h- | -Our current install instructions don't scale as we have one copy for each device.-
411
-We also created generic instructions but they tend to be harder to follow[1] than the device specific ones.-
412
-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.-
413 214 Denis 'GNUtoo' Carikli
-The instructions will need to be able to be modified and compiled on an FSDG compliant distribution.-
414
Mostly done: 
415
* The installation instructions are now generic enough. 
416
* Some long standing TODO were also done along the way like adding backup instructions for the EFS.
417
* The current instructions are still for Replicant 6.0 and will need to be updated for Replicant 9.0 |

* It might be interesting to contact the people doing ports once we have something working well enough.
464
* It is also interesting to look at other attempts to understand if a given device is powerful enough to run Android 9 and what configuration was used to achieve it.
