Move meta-agl-profile-graphical-html5 and meta-pipewire into the main layer
Reasoning: - the profile-graphical-html5 belongs in the main layer - meta-pipewire is enabled by default For reference - the original location is: https://gerrit.automotivelinux.org/gerrit/gitweb?p=AGL%2Fmeta-agl-devel.git;a=commit;h=8479cd0c37e5e5e207a16f21c864610103e4f20f Bug-AGL: SPEC-3453 Signed-off-by: Jan-Simon Möller <jsmoeller@linuxfoundation.org> Change-Id: Ib475331bb6f84437020728fbb3f17b4acaab0106 Reviewed-on: https://gerrit.automotivelinux.org/gerrit/c/AGL/meta-agl/+/24875 Reviewed-by: Scott Murray <scott.murray@konsulko.com>

+meson 0.50 is not really needed, but there are some strange warnings

+yet, so let's not fail compilation because of that...

+Subject: [PATCH] gst: Implement new pwaudio{src,sink} elements, based on
+ GstAudioBase{Src,Sink}
+
+These are much more reliable elements to use for audio data.
+* GstAudioBaseSink provides a reliable clock implementation based
+ on the number of samples read/written
+* on the pipewire side we make sure to dequeue, fill and enqueue
+ a single buffer inside the process() function, which avoids
+ underruns
+
+Both elements share a common ringbuffer that actually implements
+the pipewire integration.

+Subject: [PATCH] module-access: add same-sec-label-mode
+
+This is a mode where the access module allows all clients that have
+the same security label as the pipewire daemon, and every other
+client is put on the restricted state.
+
+In systems that use SMACK security labels, such as AGL, this allows
+the session manager (which is spawned by pipewire, inheriting the
+same smack label) to have full access to all objects, while every
+other client is restricted and the session manager must decide
+what to do with it
+
+Note that while this option is configurable, there is no loss of
+security if this option is not set in the configuration. Clients
+that don't have the same security context will be considered to
+be flatpak clients because pipewire will not be able to open
+/proc/pid/cmdline. This however results in some unwanted error
+messages that may be confusing.
+
+Upstream-Status: Inappropriate [agl/smack specific]

+Subject: [PATCH] alsa-pcm: call reuse_buffers when resetting the state of the
+ buffers
+
+This allows the upstream node to put buffers back to its pool in case
+they were left around in the ready list locally when the alsa-pcm-sink
+was last paused.
+
+Fixes #203
