7 | h3. Status with AOSP 9 |
||
8 | |||
9 | 98 | Denis 'GNUtoo' Carikli | * 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 |

26 | 1 | Denis 'GNUtoo' Carikli | |
27 | 100 | Denis 'GNUtoo' Carikli | 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 | |

90 | 104 | Denis 'GNUtoo' Carikli | </pre> |
91 | 1 | Denis 'GNUtoo' Carikli | |
92 | 104 | Denis 'GNUtoo' Carikli | h4. Launching the build |
93 | 1 | Denis 'GNUtoo' Carikli | |
94 | 118 | Denis 'GNUtoo' Carikli | Follow the "i9300 manifest instructions:":https://github.com/CustomRoms/android_local_manifests_i9300 |
95 | 104 | Denis 'GNUtoo' Carikli | <pre> |
96 | 118 | Denis 'GNUtoo' Carikli | $ subject='/C=US/ST=California/L=Mountain View/O=Android/OU=Android/CN=Android/emailAddress=android@android.com' |
97 | $ mkdir .android-certs |
||
98 | $ for x in releasekey platform shared media testkey; do \ |
||
99 | ./development/tools/make_key .android-certs/$x "$subject"; \ |
||
100 | done |
||
101 | $ parallel_tasks=$(echo "$(grep 'processor' /proc/cpuinfo | wc -l ) + 1" | bc) |
||
102 | 104 | Denis 'GNUtoo' Carikli | $ source build/envsetup.sh |
103 | 137 | Denis 'GNUtoo' Carikli | $ lunch lineage_i9305-eng |
104 | 118 | Denis 'GNUtoo' Carikli | $ make -j${parallel_tasks} bacon |
105 | 87 | Denis 'GNUtoo' Carikli | </pre> |
106 | 136 | Denis 'GNUtoo' Carikli | |
107 | The images can then be flashed with heimdall. They are then in: |
||
108 | 1 | Denis 'GNUtoo' Carikli | <pre> |
109 | out/target/product/i9305/obj/PACKAGING/target_files_intermediates/lineage_i9305-target_files-eng.replicant/IMAGES/ |
||
110 | 142 | Denis 'GNUtoo' Carikli | </pre> |
111 | |||
112 | h4. Getting lastest changes |
||
113 | |||
114 | * 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 much dirty, so be sure to backup your local changes. |
||
115 | * 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: |
||
116 | <pre> |
||
117 | $ rm -rf .repo/manifests/ # This enables me to force push and rebase the manifest repository as well |
||
118 | $ repo init -u https://git.replicant.us/GNUtoo/manifest.git -b GNUtoo/lineage-16.0-base |
||
119 | $ repo sync --force-sync |
||
120 | </pre> |
||
121 | * 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: |
||
122 | <pre> |
||
123 | $ repo sync --force-sync |
||
124 | 136 | Denis 'GNUtoo' Carikli | </pre> |
125 | |||
126 | 138 | Denis 'GNUtoo' Carikli | h4. Install the images |
127 | |||
128 | <pre> |
||
129 | $ 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 |
||
130 | </pre> |
||
131 | |||
132 | h4. Get adb |
||
133 | |||
134 | 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: |
135 | 138 | Denis 'GNUtoo' Carikli | <pre> |
136 | $ sudo adb shell |
||
137 | * daemon not running; starting now at tcp:5037 |
||
138 | * daemon started successfully |
||
139 | i9305:/ # |
||
140 | $ sudo adb kill-server |
||
141 | $ adb shell |
||
142 | * daemon not running; starting now at tcp:5037 |
||
143 | * daemon started successfully |
||
144 | error: no devices/emulators found |
||
145 | </pre> |
||
146 | So make sure to kill the adb-server and run it as root: |
||
147 | <pre> |
||
148 | $ adb kill-server |
||
149 | $ sudo adb shell |
||
150 | * daemon not running; starting now at tcp:5037 |
||
151 | * daemon started successfully |
||
152 | i9305:/ # |
||
153 | 1 | Denis 'GNUtoo' Carikli | </pre> |
154 | 147 | Denis 'GNUtoo' Carikli | |
155 | h4. Booting |
||
156 | |||
157 | 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. |
||
158 | |||
159 | You can also follow the boot progress with adb: |
||
160 | <pre> |
||
161 | adb logcat |
||
162 | adb logcat -b main |
||
163 | </pre> |
||
164 | |||
165 | Note that the device can go into suspend at any time, so adb might be interrupted. |
||
166 | 138 | Denis 'GNUtoo' Carikli | |
167 | 141 | Denis 'GNUtoo' Carikli | h3. Fixes that needs to be done |
168 | 140 | Denis 'GNUtoo' Carikli | |
169 | * Make adb work as user by using the right USB IDs, and make userspace do the USB setup. |
||
170 | * Make the kernel not use hardcoded CMDLINE_FORCE |
||
171 | * Make the kernel not use hardcoded partitions if possible (though we use system as root) |
||
172 | 145 | Denis 'GNUtoo' Carikli | * Make a clean Gatekeeper HAL module implementation instead of using the same hack than goldfish |

||
351 | lineage-16.0 branch | hardware/samsung/macloader | | Loads the MAC Address of the WiFi network interface | Might be useful | |
||
352 | | hardware/samsung/wifiloader | | Loads the wifi kernel module (like modprobe) and setup firmware filesystems permissions | May be useful | |
||
353 | | hardware/samsung/audio | | seems to contains ril related stuff as well | Look if the ril stuff is required, go for standard audio | |
||
354 | | hardware/samsung/lineagehw/hidl/livedisplay | | livedisplay is a feature similar to what redshift does on GNU/Linux | Not sure if it works with mainline | |
||
355 | | hardware/samsung/exynos/multimedia/utils/ | seem meant for audio/video decoding offload | assembly obtimized color conversion and resize code | check assembly code license, not sure if useful | |
||
356 | | all other directories in hardware/samsung/exynos/ | nonfree firmwares, nonfree software?, smdk kernel? | audio/video decoding offload | Avoid using that | |
||
357 | | hardware/samsung/exynos3 |/2. nonfree firmwares?, nonfree software?, smdk kernel? |/2. some light libraries, display stuff (gralloc, etc), 2D acceleration (FIMG), camera (FIMC), 3D acceleration, etc |/2. Avoid using that for now | |
