Thankyou everyone for providing feedback and testing v5 patchset.
This patchset aims to provide a basic version of QCOM DSP based
audio support which is available in downstream andriod kernels.
This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and
will add support to other features as we move on.

QDSP has both static and dynamic modules. static modules like AFE
(Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager)
and CORE to provide this audio services.
All these services use APR (Asynchronous Packet Router) protocol
via smd/glink transport to communicate with Application processor.
More details on each module is availble in there respective patch.

This patchset is tested on DB820c, with HDMI audio playback, MI2S on
DB410c on top of mainline, Also tested SLIMBus analog audio using
wcd9355 with an additional patches. Patches are also tested on
SDM845 by Rohit.

Here is my test branch incase someone want to try these patches

Here is block diagram to give a quick overview of the components

  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

Thankyou everyone for providing feedback and testing v5 patchset.
This patchset aims to provide a basic version of QCOM DSP based
audio support which is available in downstream andriod kernels.
This patchset support audio playback on HDMI-RX, MI2S, SLIMBus and
will add support to other features as we move on.

QDSP has both static and dynamic modules. static modules like AFE
(Audio FrontEnd), ADM (Audio Device Manager), ASM(Audio Stream Manager)
and CORE to provide this audio services.
All these services use APR (Asynchronous Packet Router) protocol
via smd/glink transport to communicate with Application processor.
More details on each module is availble in there respective patch.

This patchset is tested on DB820c, with HDMI audio playback, MI2S on
DB410c on top of mainline, Also tested SLIMBus analog audio using
wcd9355 with an additional patches. Patches are also tested on
SDM845 by Rohit.

Here is my test branch incase someone want to try these patches
https://git.linaro.org/people/srinivas.kandagatla/linux.git/log/?h=v4.17-qdsp6

Here is block diagram to give a quick overview of the components

+Qualcomm APR (Asynchronous Packet Router) binding
+
+This binding describes the Qualcomm APR. APR is a IPC protocol for
+communication between Application processor and QDSP. APR is mainly
+used for audio/voice services on the QDSP.
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: Destination processor ID.
+	Possible values are :
+			1 - APR simulator
+			2 - PC
+			3 - MODEM
+			4 - ADSP
+			5 - APPS
+			6 - MODEM2
+			7 - APPS2
+
+= APR SERVICES
+Each subnode of the APR node represents service tied to this apr. The name
+of the nodes are not important. The properties of these nodes are defined
+by the individual bindings for the specific service
+- All APR services MUST contain the following property:
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: APR Service ID
+	Possible values are :
+			3 - DSP Core Service
+			4 - Audio Front End Service.
+			5 - Voice Stream Manager Service.
+			6 - Voice processing manager.
+			7 - Audio Stream Manager Service.
+			8 - Audio Device Manager Service.
+			9 - Multimode voice manager.
+			10 - Core voice stream.
+			11 - Core voice processor.
+			12 - Ultrasound stream manager.
+			13 - Listen stream manager.
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.
+
+	apr@4 {
+		compatible = "qcom,apr-v2";
+		reg = <APR_DOMAIN_ADSP>;

+Qualcomm APR (Asynchronous Packet Router) binding
+
+This binding describes the Qualcomm APR. APR is a IPC protocol for
+communication between Application processor and QDSP. APR is mainly
+used for audio/voice services on the QDSP.
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: Destination processor ID.
+	Possible values are :
+			1 - APR simulator
+			2 - PC
+			3 - MODEM
+			4 - ADSP
+			5 - APPS
+			6 - MODEM2
+			7 - APPS2
+
+= APR SERVICES
+Each subnode of the APR node represents service tied to this apr. The name
+of the nodes are not important. The properties of these nodes are defined
+by the individual bindings for the specific service
+- All APR services MUST contain the following property:
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: APR Service ID
+	Possible values are :
+			3 - DSP Core Service
+			4 - Audio Front End Service.
+			5 - Voice Stream Manager Service.
+			6 - Voice processing manager.
+			7 - Audio Stream Manager Service.
+			8 - Audio Device Manager Service.
+			9 - Multimode voice manager.
+			10 - Core voice stream.
+			11 - Core voice processor.
+			12 - Ultrasound stream manager.
+			13 - Listen stream manager.
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support toi APR bus (Asynchronous Packet Router) driver.
ARP driver is made as a bus driver so that the apr devices can added removed
more dynamically depending on the state of the services on the dsp.
APR is used for communication between application processor and QDSP to
use services on QDSP like Audio and others.

  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support toi APR bus (Asynchronous Packet Router) driver.
ARP driver is made as a bus driver so that the apr devices can added removed
more dynamically depending on the state of the services on the dsp.
APR is used for communication between application processor and QDSP to
use services on QDSP like Audio and others.

  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds some common helper functions like translating dsp error
to linux error codes and channel mappings etc.

These functions are used in all the following qdsp6 drivers.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to Q6AFE (Audio Front End) module on Q6DSP.

AFE module sits right at the other end of cpu where the codec/audio
devices are connected.

AFE provides abstraced interfaces to both hardware and virtual devices.
Each AFE tx/rx port can be configured to connect to one of the hardware
devices like codec, hdmi, slimbus, i2s and so on. AFE services include
starting, stopping, and if needed, any configurations of the ports.

* [PATCH v6 09/24] ASoC: qdsp6: q6afe: Add q6afe driver
@ 2018-04-26  9:45   ` srinivas.kandagatla at linaro.org

From: srinivas.kandagatla at linaro.org @ 2018-04-26  9:45 UTC (permalink / raw)
  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to Q6AFE (Audio Front End) module on Q6DSP.

AFE module sits right at the other end of cpu where the codec/audio
devices are connected.

AFE provides abstraced interfaces to both hardware and virtual devices.
Each AFE tx/rx port can be configured to connect to one of the hardware
devices like codec, hdmi, slimbus, i2s and so on. AFE services include
starting, stopping, and if needed, any configurations of the ports.

From: srinivas.kandagatla at linaro.org @ 2018-04-26  9:45 UTC (permalink / raw)
  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to LPASS Bit clock, LPASS Digital
core clock and OSR clock. These clocks are required for both
MI2S and PCM setup.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to Q6ADM (Audio Device Manager) module in
q6dsp. ADM performs routing between audio streams and AFE ports.
It does Rate matching for streams going to devices driven by
different clocks, it handles volume ramping, Mixing with channel
and bit-width. ADM creates and destroys dynamic COPP services
for device-related audio processing as needed.

This patch adds basic support to ADM.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to Q6ADM (Audio Device Manager) module in
q6dsp. ADM performs routing between audio streams and AFE ports.
It does Rate matching for streams going to devices driven by
different clocks, it handles volume ramping, Mixing with channel
and bit-width. ADM creates and destroys dynamic COPP services
for device-related audio processing as needed.

This patch adds basic support to ADM.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to Q6ADM (Audio Device Manager) module in
q6dsp. ADM performs routing between audio streams and AFE ports.
It does Rate matching for streams going to devices driven by
different clocks, it handles volume ramping, Mixing with channel
and bit-width. ADM creates and destroys dynamic COPP services
for device-related audio processing as needed.

This patch adds basic support to ADM.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on
Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup
as playback/capture. ASM provides top control functions like
Pause/flush/resume for playback and record. ASM can Create/destroy encoder,
decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on
Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup
as playback/capture. ASM provides top control functions like
Pause/flush/resume for playback and record. ASM can Create/destroy encoder,
decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to q6 routing driver which configures route
between ASM and AFE module using ADM apis.

This driver uses dapm widgets to setup the matrix between AFE ports and
ASM streams.

* [PATCH v6 17/24] ASoC: qdsp6: q6routing: Add q6routing driver
@ 2018-04-26  9:45   ` srinivas.kandagatla at linaro.org

From: srinivas.kandagatla at linaro.org @ 2018-04-26  9:45 UTC (permalink / raw)
  To: linux-arm-kernel

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to q6 routing driver which configures route
between ASM and AFE module using ADM apis.

This driver uses dapm widgets to setup the matrix between AFE ports and
ASM streams.

What is the plan for getting this patch merged?  I think the only review

Also just saw ARP->APR there.

It was initially reviewed by Bjorn and Rohit. I requested Andy to have

"depends on QCOM_APR" should prevent drivers from building without apr.

Up to you,

Andy

Yes, but what I mean is #sound-dai-cells is a property of the dais
node, but reg and qcom,sd-lines are properties of child nodes under
the dais node. It is evident in the example, but not without the
example.

Also, anywhere with reg needs #address-cells and #size-cells in the parent node.

Sorry, but I think we have discussed this before?

"buf" isn't some random buffer to be sent, it is a apr_hdr followed by
some data. As such I think you should make this type struct apr_hdr *,
or if you think that doesn't imply there's payload make a type apr_pkt
that has a payload[] at the end.

It will make it obvious for both future readers and the compiler what
kind of data we're passing here.


This comment also applies to functions calling functions that calls
apr_send_pkt() as they too lug around a void *.

Afaict all callers of this function will print an error message,
sometimes on more than one level in the stack. And if some code path
does retry sending you will get a printout for each attempt, even though
the caller is fine with it.

I would recommend unlocking the spinlock and then do:

	return ret ? : hdr->pkt_size;

I think it would be nice to make sure that hdr->pkt_size is < len as
well, to reject messages that larger than the incoming buffer.

The pkt_size should be in the ballpark of len, could this check be
changed to hdr->pkt_size != len?

Rather than doing a O(n) search for the svc with svc_id you could use a
idr or a radix_tree to keep the id -> svc mapping.

Making a verbatim copy of parts of the hdr and then passing that to the
APR devices creates an asymmetry in the send/callback API, without a
whole lot of benefits. I would prefer that you introduce the apr_pkt, as
described above, and once you have validated the size et al and found
the service you just pass it along.

Sorry, but I think we have discussed this before?

"buf" isn't some random buffer to be sent, it is a apr_hdr followed by
some data. As such I think you should make this type struct apr_hdr *,
or if you think that doesn't imply there's payload make a type apr_pkt
that has a payload[] at the end.

It will make it obvious for both future readers and the compiler what
kind of data we're passing here.


This comment also applies to functions calling functions that calls
apr_send_pkt() as they too lug around a void *.

Afaict all callers of this function will print an error message,
sometimes on more than one level in the stack. And if some code path
does retry sending you will get a printout for each attempt, even though
the caller is fine with it.

I would recommend unlocking the spinlock and then do:

	return ret ? : hdr->pkt_size;

Yes, I did mention that I would give it a try and see, This change was 
pretty intrusive when I last looked at this.

I agree with you on asymmetry! I will change this and add struc apr_pkt 
which would apr_hdr followed by payload. This should also work for 
callback as well.

Yep, It makes sense, I can add that check here.

Am not 100% sure idr is correct thing here, as the svc_ids are static 
and the list we are talking here in worst case would be max of 13 
entires, in audio case it is just 4 services.
I think using radix_tree would be over do.

Okay, this would be a big rework, I will do it in next version.

Yes, I did mention that I would give it a try and see, This change was

I agree with you on asymmetry! I will change this and add struc apr_pkt 
which would apr_hdr followed by payload. This should also work for 
callback as well.

Am not 100% sure idr is correct thing here, as the svc_ids are static 
and the list we are talking here in worst case would be max of 13 
entires, in audio case it is just 4 services.
I think using radix_tree would be over do.

The patch

   ASoC: qdsp6: dt-bindings: Add q6adm dt bindings

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.  

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

+Qualcomm APR (Asynchronous Packet Router) binding
+
+This binding describes the Qualcomm APR. APR is a IPC protocol for
+communication between Application processor and QDSP. APR is mainly
+used for audio/voice services on the QDSP.
+
+- compatible:
+	Usage: required
+	Value type: <stringlist>
+	Definition: must be "qcom,apr-v<VERSION-NUMBER>", example "qcom,apr-v2"
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: Destination processor ID.
+	Possible values are :
+			1 - APR simulator
+			2 - PC
+			3 - MODEM
+			4 - ADSP
+			5 - APPS
+			6 - MODEM2
+			7 - APPS2
+
+= APR SERVICES
+Each subnode of the APR node represents service tied to this apr. The name
+of the nodes are not important. The properties of these nodes are defined
+by the individual bindings for the specific service
+- All APR services MUST contain the following property:
+
+- reg
+	Usage: required
+	Value type: <u32>
+	Definition: APR Service ID
+	Possible values are :
+			3 - DSP Core Service
+			4 - Audio Front End Service.
+			5 - Voice Stream Manager Service.
+			6 - Voice processing manager.
+			7 - Audio Stream Manager Service.
+			8 - Audio Device Manager Service.
+			9 - Multimode voice manager.
+			10 - Core voice stream.
+			11 - Core voice processor.
+			12 - Ultrasound stream manager.
+			13 - Listen stream manager.
+
+= EXAMPLE
+The following example represents a QDSP based sound card on a MSM8996 device
+which uses apr as communication between Apps and QDSP.
+
+	apr@4 {
+		compatible = "qcom,apr-v2";
+		reg = <APR_DOMAIN_ADSP>;
+
+		q6core@3 {
+			compatible = "qcom,q6core";
