 Program of the Hands on Session
  1. Introduction
    1. What is GDP 11.
    2. What is GDP Master
    3. Hands on Session goals and expectations
  2. Where is what you need for GDP 11 and GDP Master and how to get.
  3. It is easier if you use the pre-built images: GDP 11.
    1. GDP Download page (Not available for Renesas boards)
    2. Flash sd card howto: step by step
    3. Connect cables and boot process.
    4. Boot Renesas images.
    5. UI and PoC apps:
      1. GDP in Detail
      2. Describe and boot the VM
        1. For Linux
        2. For Windows
        3. For Mac
      3. VM checks
        1. Navigate through Porter target page. (may need to install a web browser into the vm)
        2. Open a shell: change directory into GDP one. (change PATH variable!)
        3. Edit a file. Install geddit & quilt, sudo-apt
    6. Access Porter through serial & ssh.
    7. GDP components and services: kernel, systemd, weston journal, etc.
    8. YOCTO overview: 
      1. Slides: please go back to the slide deck
      2. Links: The Yocto project documentation
    9. Goal of this block
    10. GDP Master
      1. How to build GDP Master from scratch
      2. Potentially show the steps here of how to do all the git checkout stuff (mkdir GDP, clone inside it), source init look at local conf etc etc( we will then say but today we'll be using a readymade build dir)
      3. Explain the git repo, each layer we use, some basic bitbake commands maybe
      4. Troubleshooting problems build problems.
        1. Summary of this block
        2. Break: 10 min.
  4. Goal of this block
  5. Modify GDP11 - Existing GDP source
    1. Explain Porter target page instructions
    2. 'bitbake c compile gdp-hmi-launcher2'

    3. Go into the source code (tmp/work/cortexa7hf-vfp-vfpv4-neon-poky-linux-gnueabi/gdp-hmi-launcher2/1.0-r0/git)

    4. Find the file you want to alter: (app/gdp-hmi-launcher2/content/ContentModel.qml)

    5. Add it to a quilt patch

      1. Go to the launcher's app's directory ( app/gdp-hmi-launcher2,this is a special case, see what S is defined as in recipe)

      2. `quilt new remove_fsa.patch`

      3.  `quilt add content/ContentModel.qml`

    6. Make the changes to content/ContentModel.qml

    7. force-compile (bitbake -c compile f gdp-hmi-launcher2`)

    8. Make patch (`quilt refresh`)

    9. Add patch to recipes

      1. copy patches/xyza.patch to ~/genivi-dev-platform/meta-genivi-dev/meta-genivi-dev/recipes-dev-hmi/gdp-hmi-launcher2_1.0.bb

      2. add file://remove_fsa.patch/ to the SRC_URI_appends in ~/genivi-dev-platform/meta-genivi-dev/meta-genivi-dev/recipes-dev-hmi/genivi-dev-platform-hmi/gdp-hmi-launcher2_1.0.bb
      3. bitbake c clean gdp-hmi-launcher2
  6. Let's build GDP11
    a. The VM should have the image prebuilt, so hopefully only the changes from modify section to rebuild, more maybe?
  7. Modify GDP11 - Add existing package - htop (rebuild and redeploy if times allows) (RM_OLD_IMAGE = "1" if disk space is problematic)
  8. Modify GDP11 -  Create a recipe for a new package (rebuild and redeploy if time allows)
  9. Troubleshooting problems
    1. Failed deployment? Using journalctl etc etc to take a look at weston logs maybe
      1. Check the kernel log with `dmesg`
      2. Check the systemd journal with `journalctl -b` (shows all messages this boot)
      3. Check all logging for weston `journalctl -b --user-unit weston` (and if that shows nothing, `journalctl -b --unit weston`)
      4. Check that input events are being processed correctly (`libinput-list-devices` to identify the input device, and `libinput-debug-events --device /dev/input/event1` to watch the events)
  10. How to contribute to GDP project
        a. General Genivi policy
        b. Git format-patch and send mail is still valid
        c. Github - Show htop added to dev packagegroup as an example
        d. go.cd
        e. Genivi SDE
        f. Testing & feedback!
  11. New RC3 HMI

The above program will be adapted to the usage of each board.

  8. Let's build GDP-ivi9
    a. The VM should have the image prebuilt, so hopefully only the changes from modify section to rebuild, more maybe?
    b.  local.conf settings to match your build hardware? 
  9. Troubleshooting problems.
    1. Take a broken patch and fix it sounds like a useful task
      1. Mangle a patch to the hmi (edit ~/genivi-demo-platform/meta-genivi-demo/meta-genivi-demo/recipes-demo-hmi/genivi-demo-platform-hmi/gdp-hmi-launcher2/0001-gdp-hmi-launcher2-Change-the-name-of-Audiomanager-Mo.patch)
      2. Attempt a build (`bitbake genivi-demo-platform`)
      3. Remove the offending patch and any later patches from the SRC_URI (edit meta-genivi-demo/meta-genivi-demo/recipes-demo-hmi/genivi-demo-platform-hmi/gdp-hmi-launcher2_1.0.bb and remove the line "file://0001-gdp-hmi-launcher2-Change-the-name-of-Audiomanager-Mo.patch \"
      4. Go to the source code (~/genivi-demo-platform/gdp-src-build/tmp/work/cortexa7hf-vfp-vfp4-neon-poky-linux-gnueabi/gdp-hmi-launcher2/1.0-r0/git/app/gdp-hmi-launcher2)
      5. Use quilt, adding a new patch file. `quilt new 0001-rename-to-audiomanager-monitor.patch`
      6. Add the files we're expecting to alter `quilt add content/ContentModel.qml`
      7. Attempts to apply the offending patch manually `patch -p1 < patches/0001-gdp-hmi-launcher2-Change-the-name-of-Audiomanager-Mo.patch`
        This will generate a .rej file
      8. Edit the offending file (content/ContentModel.qml, not the .rej) to fix the problem.
      9. Test that it compiles by going back to ~/genivi-demo-platform/gdp-src-build and running `bitbake -c compile -f gdp-hmi-launcher2`
      10. Make a patch out of those changes `quilt refresh`
      11. Copy the new patch into recipes and add it to the gdp-hmi-launcher2_1.0.bb file (`cp patches/0001-rename-to-audiomanager-monitor.patch ~/genivi-demo-platform/meta-genivi-demo/meta-genivi-demo/recipes-demo-hmi/genivi-demo-platform-hmi/gdp-hmi-launcher2/` and edit ~/genivi-demo-platform/meta-genivi-demo/meta-genivi-demo/recipes-demo-hmi/genivi-demo-platform-hmi/gdp-hmi-launcher2_1.0.bb)
      12. Do a proper build
      13. Copy the image out of the VM, flash it to the SD card and test it
    2. Failed deployment? Using journalctl etc etc to take a look at weston logs maybe
      1. Check the kernel log with `dmesg`
      2. Check the systemd journal with `journalctl -b` (shows all messages this boot)
      3. Check all logging for weston `journalctl -b --user-unit weston` (and if that shows nothing, `journalctl -b --unit weston`)
      4. Check that input events are being processed correctly (`libinput-list-devices` to identify the input device, and `libinput-debug-events --device /dev/input/event1` to watch the events)
  10. How to contribute to GDP project.
        a. Show how to use git send mail to the list maybe?
        b. How we would take the patch from the list, apply it to the (for now qemu-ci branch) and push it to the server(show the pipeline starting a build due to the change)
        c. Show the basic outline how you could try build gdp for a new hardware target, new branch bsp-etc etc. Maybe use minnowboard as an example, checkout the branch and show it?
  11. Extension Exercise: make your own patch for the faytech monitor using these clues:

    1. Touch events on the faytech monitor (via libinput-debug-events) show touch is never released.

    2. Exploring the kernel source code (tmp/work-shared/raspberrypi2/kernel-source) shows that this is because the flag that says that the touch is "hovering" is never unset.

    3. This behaviour is used if the quirk MT_QUIRK_HOVERING is enabled

    4. The faytech monitor identifies itself via HID usage numbers (0xff0000c5) as compatible with the windows 8 touch API.

Feedback

Pease provide feedback about the hands on session in the table below or directly to Agustin Benito Bethencourt. Improving is harder without your evaluation.

Feedback collected by trainers:

  1. The   effort   put   by   GENIVI   in   these  Hands   on   Sessions   is   not   supported   by the number of participants.   We   suggest   to   take   extra  actions   to   have a full room. The effort is basically the same but the impact higher.
  2. A   single   VM   with   all   that   is   needed  for   every   Hands   on   Session   should   be  provided   to   participants the first day.   This   will   benefit  participants   and   the   Hands   on   Sessions  execution. It will make the coordination between those providing training more complicate though.
