Return-Path: From: C Shapiro To: linux-bluetooth@vger.kernel.org Cc: Simon Glass , Luiz Augusto von Dentz , Marcel Holtmann , Eramoto Masaya Subject: [PATCH v4] Support to change set file via arg Date: Thu, 3 Aug 2017 11:20:03 -0600 Message-Id: <20170803172003.81839-1-shapiroc@chromium.org> List-ID: ChromeOS is currently shifting to a more dynamic build system where a single build will be created/managed/deployed to support multiple models that were all created based on a single reference board. This is being done for general cost/maintenance savings around the sheer number of builds that are currently managed for ChromeOS. To support this, we're changing our build images to have all of the configuration available for all of the models supported by a given build. For the bluetooth stack, models have different product id values in the DeviceID field for the main.conf config file. E.g. - https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master/overlay-pyro/chromeos-base/chromeos-bsp-pyro/files/main.conf - https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master/overlay-reef/chromeos-base/chromeos-bsp-reef/files/main.conf - https://chromium.googlesource.com/chromiumos/overlays/board-overlays/+/master/overlay-snappy/chromeos-base/chromeos-bsp-snappy/files/main.conf This change allows the config file to be passed as a runtime argument to bluetoothd, which allows the ChromeOS init script to determine the model at runtime and then pass the appropriate model specific config file. This change is also beneficial in general development since the conf file can be easily edited and the src file location then be used directly.
