Questions for discussion:

1. What can we do to improve developer on-boarding for AGL?
   1. Lisandro: Platform team had difficulty with the set up scripts that we provided. Need to be improved.
   2. Found it easy to wire up the back end with KUKSA running in a container.
   3. Justin: Found it difficult to make changes in Flutter and deploy them. Had to use the Yocto build system rather than an IDE that they run on their desktop.
   4. Scott: the initial pieces are in place, but work needs to be done.
   5. Joel: Are there Jira tickets or other communication around the issue? Could be fixed in an hour or so.
   6. Walt; Have we documented the requirements and what the expectations are?
   7. Dorothy: hardware access

1. What did you find easy or difficult to use in the Flutter embedder? What improvements can we make in the experience?
   1. Lisandro: Issues were resolved quickly by the AGL dev team as ICS found them

1. What additional services would be helpful to add to the AGL interface?

1. Finally I would like your thoughts on what improvements or expansions we can make to the Flutter apps and how easy or difficult it would be to reuse the code for a landscape version of the apps using the same display.
   1. David: This would not be too difficult to do, I would estimate about a day or two of effort depending on the competence of the developer. There are libraries that can be used for this and many of the components will scale.
   2. Getting video working would be big win. Is there a way to get upstream video plug-ins running?

From Toyota(advance comments)

• The files below are the same name files, but at the moment there are some differences between the two.
• ./service/system/task_manager/client/libtskmcfg/conf/agl_thread.h
• ./agl-basefiles/include/agl_thread.h ^^
  • question: use different names to not confuse ? e.g. agl_thread_tm.h ?
• So our ideas are to keep the two in basesystem.git at the current state and to refactor them from next year.

• Current HALs are stub and they don't have function.
  • As actual product, Basesystem has HALs and cannot be separated for supplier.
  • TOYOTA and related company are implementing only can_hal for R-Car aiming for June.
    • question: what makes the can_hal rcar-specific ? (only vcan - Kurokawa-san)
    • question: what is the abstraction provided by the can_hal (and other *_hal) .
      • e.g. over the BSP like meta-rcar-gen3
      • or e.g. why need to abstract the standard linux kernel socketcan

• Almost all of the other review comments are done but I don't have good answer for
  • https://git.automotivelinux.org/staging/basesystem/tree/agl-systemd/99-agl.rules
    • MODE 666 or 777 → security ??
      • MODE 666 → 660
      • MODE 777 → 770
    • Are these better ?
      • Yes. But: you might have to use group and group membership for the apps reading/writing from these then. E.g. for 'drm' in the agl-demo-platform with smack, there is a 'display' group and any app requiring display access need to be member of the 'display' group. Similar there is an 'audio' group.
      • example (with smack): https://git.automotivelinux.org/AGL/meta-agl-demo/tree/recipes-graphics/wayland/weston-init/zz-dri.rules.in
      • or app/service runs as 'root'

• xpath:
  • need in recipe: 'inherit perlnative' (Nomoto-san)
  • need to patch xpath recipe to use '#!/usr/bin/env perl' (Scott)

AI:

• check if documentation about HAL can be shared
• review agl-basefiles recipe. are these needed at all given:
  • headers are installed by the recipes that ship them
    • agl-basefiles/agldd: these headers originate in the evk.
    • They should be shipped evklib-headers.bb
    • meta-oem-production-readiness/meta-agl-basesystem/recipes-kernel/kernel-module-evklib/evklib-headers .
  • include/ cannot be split.
    • https://confluence.automotivelinux.org/pages/viewpage.action?pageId=32833688

Plan:

• any pending changes to basesystem.git go first,
• then merge recipes (if the image builds)

  • Monday, December 21st 2pm

Attendees: Nomoto-san,

• Agenda review
• Basesystem review

1. - Need quick intro from Toyota what is where (very brief does each folder contain)
   • agl-basefiles: used by all other components (e.g. Makefiles, some headers)
   • agl-systemd: systemd files used to start systemmanager
   • hal: SOC abstraction
   • module: kernel module
   • service: contains all function source code
   • stub: stub functions
2. - Questions:
   • agl-basefiles
     • agl_thread.h vs sm_launch_conf.h ???? they look basically same ??
     • agl_types_obsoluted.h → agl_types_deprecated.h
       • obsolete = no longer in use (aka should not be used at all)
       • deprecated = still in used but being faded out / reworked / replaced
     • ifdef KERNEL + license mentioned in header
   • agl-systemd
     • https://git.automotivelinux.org/staging/basesystem/tree/agl-systemd/99-agl.rules
       • MODE 666 or 777 → security ??
   • kernel-module-evklib:
     • https://git.automotivelinux.org/staging/basesystem/tree/module/kernel-module-evklib/evk_lib.c#n56
     • evk_lib.h → check
   • stub:
     • clock/localtime: why duplicate zoneinfo ? → there is tzdata package in yocto ?
3. - Q&A

• Yocto recipe review (gerrit)

1. - walkthrough on recipes in gerrit
   • 25647 ok, pending changes to basesystem (agldd)
   • 25648 ok, but pending changes to kernel module
   • Fails to compile: 25652
     • | ./src/resmgr_api_lib.c:19:10: fatal error: resmgr_api.h: No such file or directory
     • possibly generated? → need to fix build dependency !
2. - discussion on simplification and path forward
   • 'SDKTARGETSYSROOT=${STAGING_DIR_HOST}'“ not required ('–sysroot=${STAGING_DIR_HOST}' is already part of the $CC variable !
     • – influences basesystem-common.bbclass
     • – Makefile makros in basesystem.git
3. - work on recipes
   • 25647-25651 (JS & Scott) BSMAKE_FILE fix
   • 25652 Tanikawa-san (resmgr_api.h)
   • 25653-25654 → Nomoto-san (xpath and BSMAKE_FILE)
   • Nomoto-san: need to deal with basesystem.git issues mentioned above
     • agl-thread.h
     • agl_types_obsoluted.h
     • evk_lib.h
     • stub/clock/localtime ?
     • 'SDKTARGETSYSROOT=${STAGING_DIR_HOST}'” not required ('–sysroot=${STAGING_DIR_HOST}' is already part of the $CC variable !

* Next meeting on wednesday.
