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)

Next call: January 7th 2021

  • 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.
