      @doniks I managed to figure out a workaround, I had to pull the jessie version of libssl1.0.0 so I could force ADBd to run instead, for whatever reason, my debian rootfs never gets USB tethering up unless it's the debug bootmode option. I am actually working with a running debian root now, however I screwed up while building my system image and didn't have any vendor blobs for libhybris to work with πŸ˜• I'm rebuilding my system image now and then I'm going to reinstall the halium rootfs with the new system image.

      Before-posting Edit: Looks like I'm running into an issue where the build system isn't picking up my vendor tree πŸ˜• even after popping MOB30X's binaries down in there as laid out in the LineageOS guides for setting this folder up, every system image I build continues to not contain the proprietary blobs... I can't tell if I'm doing something wrong, or if it's something else that I'm not doing first.

      EDIT EDIT: WOO! Had to do some linking around libhybris-egl, but I was able to finally get test_hwcomposer to show the spiral! Working on getting wayland to start up (working on getting some VTs up so I can launch weston as a test)

      EDIT: Weston starts as long as I specify fbdev-backend and use msm_fb_refresher to get it up and running, but it runs and it's snappy. I just can't get anything else wayland to work (gnome-shell --display-server, kwin_wayland, etc)

        Which debian rootfs are you using?
        I just wanted to inform you that my work on the debian buster rootfs is now nearly finished and it boots to ssh, the lxc container starts and libhybris also works.
        I have some pre-built one around here: https://archive.org/download/halium-debian-rootfs/halium-debian-rootfs_20171024.tar.gz and the source for the rootfs-builder has moved here: https://github.com/debian-pm/rootfs-builder.

          FWIW, it might be conceivable to fix this thing about pidns_operations in a better way. I was poking around in the upstream kernel

          git clone  --depth 1 --branch v4.13.11  https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
          grep --color=always  -nr -C 3 -Ee'CONFIG_PID_NS|pidns_operations' |less -R
          

          and I see some stuff that is not present in the kernel I use. But, well, that's for another day. Afterall, I don't even know whether it's an actual problem right now πŸ˜›

            @JBBgameich I believe I was using the debian stable rootfs. Like I said, the issue was caused by an error I made while building the rootfs. I had forgotten to build the libhybris parts so it wasn't able to communicate with the Android parts once it was up and running, managed to fix that and get up and running.

            My project trees have been put to the side for now because of my I.T. work, it hasn't left me much time for anything still. But I did see that there is now a flo image up on the ubports system image server.

            (Ninja Edit: My custom 3.4.0-5 kernel tree builds again! Fixed the defconfig)

              Trying to revive this again.

              I can get the halium rootfs running as well as before, including test_hwcomposer.

              But using the latest plasma rootfs, I get only a black screen. Also, I'm not hearing the audible PM greeting "Oh it's gorgeous".

              I have replaced the vendor blobs with the ones provided by TheMuppets:

                <project
                    path="vendor"
                    name="proprietary_vendor_asus"
                    revision="cm-14.1"
                    remote="them"
                    />
              

              but that didn't help either.

              • syslog https://paste.ubuntu.com/26340223/ It continues forever and ever with the line kgsl kgsl-3d0: |kgsl_add_fence_event| invalid fence fd
              • logcat https://paste.ubuntu.com/26345905/ , repeats those four lines forever
              • lxc-checkconfig see here and there, definitely something to do there, including bugs in lxc-config :(, but I'm not convinced this is related to the problem at hand, since I got PM to work last August without having those lxc-checkconfig items solved

              Any advice appreciated!

              Update: it seems that the pm rootfs from 20171219 does work ok, but the one from 20171220 fails.

              Update2: Another image from CI also works http://mobile.neon.pangea.pub:8080/view/All/job/generic_rootfs/68/artifact/result/halium-rootfs-generic.tar.gz

              Update3: But with both, 1219 and 68/artefact the system doesn't react to touch AFTER unlocking. The lock screen itself looks ok

              • plasma_logs: https://paste.ubuntu.com/26370483/
              • logcat : https://paste.ubuntu.com/26370484/
              • dmesg: https://paste.ubuntu.com/26370482/

              0_1515740234641_Image1673683779.jpg

              Update4: With some playing around I found that the first "bad" image is 1210. Images before are ok. Then I was playing around with 1210 for a while, and it actually became unfrozen. I'm not 100% sure what I did but I think it went something like this:

              systemctl disable NetworkManager
              systemctl mask NetworkManager 
              reboot 
              ...
              # frozen 
              systemctl unmask NetworkManager 
              systemctl enable NetworkManager 
              loginctl kill-session c1 
              # screen goes dark 
              systemctl stop simplelogin 
              systemctl start simplelogin 
              # htop shows a busy system including plasma and kwin stuff 
              echo 200 > /sys/class/leds/lcd-backlight/brightness
              # shows the lock screen 
              # unlock 
              # kwallet wizard shows 
              # cancel 
              # normal system shows and 
              # is NOT frozen, I can start chromium!
              

              Oh, and I did also enable wifi (`echo 1>/dev/wcnss_wlan ;
              echo sta > /sys/module/wlan/parameters/fwpath ;
              nmcli dev wifi connect <SOMEOPENWIFI> ) but I can't remember where in the sequence above.

                I'm trying to get ubports-boot to work follwing
                https://docs.ubports.com/en/latest/porting/introduction.html ~~and
                https://github.com/ubports/docs.ubports.com/pull/67~~

                but I'm stuck at usb iSerial saying "I hit a nail" and then it goes into telnet.

                I think I tracked it down to
                mount -o bind ${rootmnt}/run/image.fstab $FSTAB || panic "drop to adb" panicking, which in turn seems to be due to this line mount -o rw,nosuid,noexec,relatime,mode=755 -t tmpfs tmpfs ${rootmnt}/run
                https://github.com/ubports/ubports-boot/blob/master/initramfs/scripts/touch#L377 failing with status 255.

                This is my dmesg https://paste.ubuntu.com/26384482/
                with some extra logging I have added prefixed with UT.init
                anybody has a clue?

                Update: Somehow I had the image files mixed up. Be sure to clean /data up if you go from halium/pm rootfs' to ubports.

                Next hickup was a problem with sshd, workaround is here: https://gist.github.com/doniks/2ac14a1bb6750165bf782f62139c8aab#file-gistfile1-txt-L61

                Now I have ssh access but lxc isn't working, seems something went wrong again with rootstock and installing the android image.

                To be continued ....

                      Gave it another spin.

                      The general steps to get deb working are much simplified since it's all in github now: https://github.com/Halium/halium-devices/blob/halium-7.1/manifests/asus_deb.xml - just follow the halium documentation. However, I'm wondering whether I should leave the OP as is, some people have expressed that it helped them in their ports to see the journey ...

                      Plasma mobile hasn't been sleeping. I can tell that the newer images work much better than previously.

                      For ubports, I made another attempt, but no GUI so far. Any tipps appreciated!

                      What I did in detail:

                      • Follow the steps on https://docs.ubports.com/en/latest/porting/introduction.html
                      • in rootstock-touch-install
                        • insert the line do_shell "rm -f /data/system.img" as the first line in prepare_ubuntu_system, otherwise we have that thing left over from halium
                        • insert the line IMAGE_SIZE=$(( $IMAGE_SIZE * 2 ))right after that variable is set, otherwise the image is too small, so I just double it
                        • delete the line do_shell "ln /data/ubuntu.img /data/system.img", otherwise I end up with an empty system.img on the device ... Not sure what the problem was exactly, I think something goes wrong with the loop devices stepping on each others toes .. not sure
                      • now I can install using the latest ubports xenial root fs: build 298 form https://ci.ubports.com/job/xenial-rootfs-armhf/
                      • at first that wouldn't boot, so ...
                      • I make ubports boot a bit more verbose halium/ubports-boot
                        • append quite=n debug=y to the UBPORTS_BOOTIMG_COMMANDLINE in Android.mk
                        • insert [ -f /dev/kmsg ] || mknod -m 600 /dev/kmsg c 1 11 in initramfs/init right before the mkdir -p /var/lock line
                        • change the line in initramfs/scripts/functions : _log_msg() from printf "$@" to printf "$@" | tee /dev/kmsg
                        • now I could sprinkle around log_warning_msg blabla in initramfs/init and see everything nicely in last_kmsg.
                        • eventually I found that it panics at the line: mount -n -o move /proc ${rootmnt}/proc ... I have simply commented this line for the moment, that avoids the panic and
                      • now it boots into the ubports rootfs
                      • however, no GUI comes up
                      • in /var/log/lightdm/lightdm.log I see
                      Launching process 2998: /usr/share/ubuntu-touch-session/usc-wrapper --file '/run/mir_socket' --from-dm-fd 11 --to-dm-fd 14 --vt 1

                      • I get a Segmentation fault (core dumped)
                      • when I run at the same time /system/bin/logcat | grep -Eve "NetlinkListener|rmt_storage" I don't see anything logged at the time of the segfault

                      Not sure what to do next. Maybe try halium-boot, maybe check the

                      lxc-checkconfig: http://paste.ubuntu.com/p/5Z6w8Kwcm6/

                      it still flags some things. Also, mabye related, I get

                      # lxc-attach -n android
                      lxc-attach: cgroups/cgfs.c: lxc_cgroupfs_attach: 2538 could not move attached process 10995 to cgroup of container

                      However,

                      # lxc-info -n android
                      Name:           android

                      PID:            1116
                      IP:             10.15.19.82
                      IP:             192.168.179.127
                      

                      and it's all seemingly good enough for plasma mobile, so not sure.

                      Again, tips welcome!

                          Thanks! I do know πŸ™‚ And I did get invaluable help from there! I would be no where without it.

                          However, after piling up a couple of hacks I find it helpful to take a step back and summarize the status quo again which is hard in irc/telegram.

                          And also, I like to mix the different styles of working: Specific tips for a specific problem in the more ad-hoc irc and the long haul, asynchronous conversation of a forum/mailing list.

                          Oh wait ... ubports porting. No I didn't know that one! I was talking about the #halium channel. I'll have a look. Thanks.

                            @doniks maybe @UniSuperBox can comment a bit on the manual tweaks you had to do for rootstocking the device, actually all should come out of the box somehow. Then, if plasma mobile shows a screen, we should be able to do this, too right?

                              Well, in a way he did πŸ™‚ The PR for the update of docs.ubports is in, which means both ubports-boot and rootstock-install can take their bugs with them to the grave.

                              Then, if plasma mobile shows a screen, we should be able to do this, too right?

                              One would hope so. However, even with halium-boot (and a bunch more kernel configs it wanted) I managed just now to build and boot it, but I end up with the same segfaults 😞

                              I spoke to @UniSuperBox and @bshah earlier today on telegram. There was a theory about something with libhybris and "N linker" but I didn't really get it and atm still just google logo.

                                    Great that you found it helpful! Maybe you want to write your own?! I think this one for N7 is very dated by now. Lots of things discussed here should be automatic/easier/well documented...
