-Object: Provide a Hook on Alsa PCM to check permission again AGL Advance Audio Agent
-Status: Release Candidate
-Author: Fulup Ar Foll fulup@iot.bzh
-Date : August-2017
-
-Functionalities:
- - Execute a set of websocket RPC request again AGL binders to allow/deny access
- - Keep websocket open in an idepandant thread on order to monitor event receive from AGL audio agent
-
-Installation
- - Alsaplugins are typically search in /usr/share/alsa-lib. Nevertheless a full path might be given
- - This plugin implement a hook on a slave PCM. Typically this slave PCM is a dedicated virtual channel (eg: navigation, emergency,...)
- - Config should be place in ~/.asoundrc (see config sample in PROJECT_ROOT/conf.d/alsa)
-
-Test
- - Install a full .asoundrc from conf.d/project/alsa.d
- - speaker-test -DMyNavigationHook -c2 -twav
-
-Config
-```
-# Define sharelib location and entry point
-# -----------------------------------------
-pcm_hook_type.MyHookPlugin {
- install "AlsaInstallHook"
- lib "/home/fulup/Workspace/AGL-AppFW/audio-bindings-dev/build/Alsa-Plugin/Alsa-Hook-Callback/alsa_hook_cb.so"
-}
-
-# Create PCM HOOK with corresponding request calls to AGL Audio Agent
-# --------------------------------------------------------------------
-pcm.MyNavigationHook {
- type hooks
- slave.pcm "MyMixerPCM"
-
- # Defined used hook sharelib and provide arguments/config to install func
- hooks.0 {
- type "MyHookPlugin"
- hook_args {
- verbose true # print few log messages (default false);
-
- # Every Call should return OK in order PCM to open (default timeout 100ms)
- uri "ws://localhost:1234/api?token='audio-agent-token'"
- request {
- # Request autorisation to write on navigation
- navigation-ctl {
- api "control"
- verb "dispatch"
- args "{'target':'navigation', 'args':{'device':'Jabra SOLEMATE v1.34.0'}}"
- }
- # subscribe to Audio Agent Event map them to signal
- subscribe-evt {
- api "control"
- verb "monitor"
- }
- }
- # map event reception to self generated signal
- event {
- pause 30
- resume 31
- stop 3
- }
- }
- }
-}
-
-```
-
-NOTE:
-
-* Hook plugin is loaded by Alsa libasound within player context. It inherits client process attributes, as UID/GID or
-the SMACK label on AGL. This smack label is tested by AGL security framework when requested a call on the audio-agent binder.
-As a result the call will only succeed it the permission attached the application in Cynara matches.
-
-* Hook plugin keep a connection with the Audio-Agent until PCM is closed by the application. This connection allow the
-Audio-Agent to send events. eg: pause, quit, mute, ... \ No newline at end of file

-Hal-Plugin
-
-Object: Add virtual soft control to sound card
-Status: Proof of concept and not a usable product
-Author: Fulup Ar Foll
-Date : June-2017
-
-HAL-plugin allows:
- - to expose any existing NUMID under a customized label name, this is order to abstract sound card config.
- - to add non alsa NUMID supported through a callback mechanism (eg: volume rampdown, power off, ...)
-
-installation
- - Plugin should be placed where ever alsaplugins are located (typically: /usr/share/alsa-lib)
- - Callback sharelib directory should be declare in $LD_LIBRARY_PATH
-
-Config
-```
-cat ~/.asoundrc
- ctl.agl_hal {
- type afbhal
- devid "hw:4"
- cblib "afbhal_cb_sample.so"
- ctls {
- # ctlLabel {numid integer name "Alsa Ctl Name"}
- MasterSwitch { numid 4 name "My_First_Control" }
- MasterVol { numid 5 name "My_Second_Control" }
- CB_sample { ctlcb @AfbHalSampleCB name "My_Sample_Callback"}
- }
- pcm.agl_hal {
- type copy # Copy PCM
- slave "hw:4" # Slave name
- }
-```
-
-With such a config file
- - numid=4 from sndcard=hw:4 is renamed "My_First_Control"
- - numid=4 from sndcard=hw:4 is renamed "My_Second_Control"
- - numid=4 will call AfbHalSampleCB from afbhal_cb_sample.so
-
-Note: to really implement a usable HAL at minimum every ALSA call should be implemented and read/write of values should be normalised from 0 to 100% with a step of 1.
-
-Conclusion: This demonstrate that implementing a HAL that both abstract ALSA get/set and enable non ALSA support is possible at an acceptable cost
-without having to hack ALSA source code. The beauty of the model is than it is fully transparent to any ALSA application. The limit is that the plugin is loaded
-within every application context, thus interaction with an external event loop remains complete as well as conflict management in case of share resources.
