Hi,

=C2=A0 I am new to the automotive/embedded xen proje= ct but have interest in the space. Where can I get the current status of th= e project including any existing hardware support. Specifically, which deve= lopment boards are currently supported and any user guides to start development?

Thanks!

Artem,

I am just = summarising some key points from our conversation. Here are some of my = thoughts

=3D Low Hanging Fruit = =3D

=3D=3D Mailing List =3D=3D
One of = the issues we have is that the mailing list is still very quiet. Part of = the reason is that much of the development work is currently happening = in Linux upstream and Xen upstream. The mailing lists are the heart of = the community, and unless we get the traffic up, it will be challenging = to get others involved. The first thing that is needed, is to start = using the list.

A number of easy way to address = this, until we get the actual automotive repositories sorted and the = code into them, would be to
* CC embedded-pv-devel@l= ists.xenproject.org to conversations that relate to Linux upstream, = Xen upstream and others where you lay the groundwork for the = project
* Given that some conversations have already been = started elsewhere, maybe you can send a mail to embedded-pv-devel@l= ists.xenproject.org with pointers to relevant discussions where = you may want wider community input, such as
** Add sound to = front-end driver - http://www= .gossamer-threads.com/lists/xen/devel/362595
** arm: = introduce basic Renesas R-Car Gen2 platform support - http://www= .gossamer-threads.com/lists/xen/devel/362335
** = Etc.
* Members of your team could lead some discussions on the = mailing list. If you look at ht= tp://xenproject.org/developers/teams/windows-pv-drivers.html (and=  h= ttp://lists.xenproject.org/archives/html/win-pv-devel/2015-01/) - = this is what we are currently doing for the Windows PV Drivers = subproject. In November, all messages were from Citrix on the list, but = in December and January there were first posts from others. =  

The other suggestion I would want to = make is that we post minutes of our meetings on the list and/or that = Artem posts monthly project updates to the = list.

Further, if you create white-papers such = as http://wik= i.xenproject.org/wiki/Automotive_Whitepapers, please send an e-mail = to embedded-pv-devel@l= ists.xenproject.org, but CC = xen-devel. 

The other thing which is quite = important is being timely in responding to questions from embedded-pv-devel@l= ists.xenproject.org.

=3D=3D Project Page is = out-of-date =3D=3D
The other issue we have is that http://xenproject.org/developers/teams/embedded-and-automotive.html=  is out of date. There are a number of options:
* I can = give Artem write access to the website - but finding your way around = Joomla is quite tedious
* Alternatively, just post what you = want changed to embedded-pv-devel@l= ists.xenproject.org and then I can go and fix = it

For news pieces on http://xenproject.org/developers/teams/embedded-and-automotive.html=  I could generate a widget that consumes an RSS feed. This would = look similar to "MIRAGE OS NEWS" on the right hand side of http://xenp= roject.org/developers/teams/mirage-os.html. To do this, we would = need some means of generating the RSS feed. This could either be a blog, = or an RSS feed builder (something like WebRSS or = similar).

If it was a blog, I can also include = it into http://xenproject.org/plane= t-xen.html 

=3D Automotive Targeted = Event =3D

We also discussed whether we can host = an automotive event in Europe. We would be talking of a 1 day event, = somewhere in Europe, for 50 people, before the summer holidays targeted = at tier 1 OEMs, car manufacturers. 

As we = discussed this is only doable, if we can find a vendor who would = volunteer to host such an event. Otherwise the costs would be too = prohibitive. As we both agreed, we will approach a number of vendors and = then report back to the list.

=3D Code = Repositories =3D 
One of the things which is extremely = important, is that we start getting the code which was listed in http://wiki.xenproject.org/wiki/Emb= edded_and_Automotive_PV_Drivers/Project_Proposal#Subproject_Proposal&n= bsp;out into the open. If this is not feasible, or not applicable any = more because the drivers are going elsewhere, we ought to change the = approach and reset expectations. This doesn't have to be a big bang: we = just need to get the repos created and see some activity. Not having the = code, is the biggest chicken and egg-problem in bootstrapping a = community.

Artem,

I am just = summarising some key points from our conversation. Here are some of my = thoughts

=3D Low Hanging Fruit = =3D

=3D=3D Mailing List =3D=3D
One of = the issues we have is that the mailing list is still very quiet. Part of = the reason is that much of the development work is currently happening = in Linux upstream and Xen upstream. The mailing lists are the heart of = the community, and unless we get the traffic up, it will be challenging = to get others involved. The first thing that is needed, is to start = using the list.

A number of easy way to address = this, until we get the actual automotive repositories sorted and the = code into them, would be to
* CC embedded-pv-devel@l= ists.xenproject.org to conversations that relate to Linux upstream, = Xen upstream and others where you lay the groundwork for the = project
* Given that some conversations have already been = started elsewhere, maybe you can send a mail to embedded-pv-devel@l= ists.xenproject.org with pointers to relevant discussions where = you may want wider community input, such as
** Add sound to = front-end driver - http://www= .gossamer-threads.com/lists/xen/devel/362595
** arm: = introduce basic Renesas R-Car Gen2 platform support - http://www= .gossamer-threads.com/lists/xen/devel/362335
** = Etc.
* Members of your team could lead some discussions on the = mailing list. If you look at ht= tp://xenproject.org/developers/teams/windows-pv-drivers.html (and=  h= ttp://lists.xenproject.org/archives/html/win-pv-devel/2015-01/) - = this is what we are currently doing for the Windows PV Drivers = subproject. In November, all messages were from Citrix on the list, but = in December and January there were first posts from others. =  

The other suggestion I would want to = make is that we post minutes of our meetings on the list and/or that = Artem posts monthly project updates to the = list.

Further, if you create white-papers such = as http://wik= i.xenproject.org/wiki/Automotive_Whitepapers, please send an e-mail = to embedded-pv-devel@l= ists.xenproject.org, but CC = xen-devel. 

The other thing which is quite = important is being timely in responding to questions from embedded-pv-devel@l= ists.xenproject.org.

=3D=3D Project Page is = out-of-date =3D=3D
The other issue we have is that http://xenproject.org/developers/teams/embedded-and-automotive.html=  is out of date. There are a number of options:
* I can = give Artem write access to the website - but finding your way around = Joomla is quite tedious
* Alternatively, just post what you = want changed to embedded-pv-devel@l= ists.xenproject.org and then I can go and fix = it

For news pieces on http://xenproject.org/developers/teams/embedded-and-automotive.html=  I could generate a widget that consumes an RSS feed. This would = look similar to "MIRAGE OS NEWS" on the right hand side of http://xenp= roject.org/developers/teams/mirage-os.html. To do this, we would = need some means of generating the RSS feed. This could either be a blog, = or an RSS feed builder (something like WebRSS or = similar).

If it was a blog, I can also include = it into http://xenproject.org/plane= t-xen.html 

=3D Automotive Targeted = Event =3D

We also discussed whether we can host = an automotive event in Europe. We would be talking of a 1 day event, = somewhere in Europe, for 50 people, before the summer holidays targeted = at tier 1 OEMs, car manufacturers. 

As we = discussed this is only doable, if we can find a vendor who would = volunteer to host such an event. Otherwise the costs would be too = prohibitive. As we both agreed, we will approach a number of vendors and = then report back to the list.

=3D Code = Repositories =3D 
One of the things which is extremely = important, is that we start getting the code which was listed in http://wiki.xenproject.org/wiki/Emb= edded_and_Automotive_PV_Drivers/Project_Proposal#Subproject_Proposal&n= bsp;out into the open. If this is not feasible, or not applicable any = more because the drivers are going elsewhere, we ought to change the = approach and reset expectations. This doesn't have to be a big bang: we = just need to get the repos created and see some activity. Not having the = code, is the biggest chicken and egg-problem in bootstrapping a = community.

Author: Andrii Tseglytskyi Date: Tue Dec 30 18:38:55 2014 +0200 xen/arm: always use count number to release hardware irq As soons as hardware interrupts are always mapped 1 to 1 count number plus 32 is always equal to interrupt number which should be released. In current implementation if we don't receive any irq which number should be released existing p->irq number will be equal to 0, and interrupt will be not released properly.

In current implementation if we don't receive any irq which number should be released existing p->irq number will be equal to 0, and interrupt will be not released properly.

We should not be able to remove an IRQ from DOM0 if it's enabled. Very bad thing could happen, such as the IRQ still in LRs...

It also means that attendees from other Chinese cities will be able to get to their home cities more easily (Friday is always extremely busy) * Option 2: April 28-29 Please let me know if you have any preferences and vote for option 1 or 2 (if you vote for option 1 let me know if you care about any specific dates) Regards Lars _______________________________________________ Embedded-pv-devel mailing list Embedded-pv-devel@lists.xenproject.org http://lists.xenproject.org/cgi-bin/mailman/listinfo/embedded-pv-devel From embedded-pv-devel-bounces@lists.xenproject.org Thu Jan 29 11:01:59 2015 Return-path: Envelope-to: archives@lists.xenproject.org Delivery-date: Thu, 29 Jan 2015 11:01:59 +0000 Received: from localhost ([127.0.0.1] helo=lists.xen.org) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YGmrG-0006VI-QB; Thu, 29 Jan 2015 11:01:58 +0000 Received: from mail6.bemta3.messagelabs.com ([195.245.230.39]) by lists.xen.org with esmtp (Exim 4.72) (envelope-from ) id 1YGmrE-0006PH-Bj for embedded-pv-devel@lists.xenproject.org; Thu, 29 Jan 2015 11:01:56 +0000 Received: from [85.158.137.68] by server-9.bemta-3.messagelabs.com id 08/1D-02995-3231AC45; Thu, 29 Jan 2015 11:01:55 +0000 X-Env-Sender: oleksandr.dmytryshyn@globallogic.com X-Msg-Ref: server-2.tower-31.messagelabs.com!1422529311!23207271!1 X-Originating-IP: [64.18.0.192] X-SpamReason: No, hits=0.5 required=7.0 tests=BODY_RANDOM_LONG X-StarScan-Received: X-StarScan-Version: 6.12.5; banners=-,-,- X-VirusChecked: Checked Received: (qmail 1723 invoked from network); 29 Jan 2015 11:01:53 -0000 Received: from exprod5og122.obsmtp.com (HELO exprod5og122.obsmtp.com) (64.18.0.192) by server-2.tower-31.messagelabs.com with DHE-RSA-AES256-SHA encrypted SMTP; 29 Jan 2015 11:01:53 -0000 Received: from mail-lb0-f178.google.com ([209.85.217.178]) (using TLSv1) by exprod5ob122.postini.com ([64.18.4.12]) with SMTP ID DSNKVMoTHj/S7cAaqXOJYDxeF5dYW1oJ/Ae8@postini.com; Thu, 29 Jan 2015 03:01:52 PST Received: by mail-lb0-f178.google.com with SMTP id u10so26723738lbd.9 for ; Thu, 29 Jan 2015 03:01:49 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=globallogic.com; s=google; h=from:to:cc:subject:date:message-id; bh=5f/8iEOjT79NwphG+VYeh3Qg4CCgiYJR+MqHUeF0vH8=; b=R5RIJJZlJaBmiZKGBKUV9LSAuc6OEEmDH2yi+H6N29NKg+bd8II9dqRWCOHFC6rZ79 x62lhNidSIMNVnhdeRJk8TRzi7IbqCFb/jkb2KnJDwxhsKspjSzFUoYRcvjgbbVU0qJs pNIaWJdgPE7vPJVX5+lYFGuO116+ECMCXzvyA= X-Google-DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=1e100.net; s=20130820; h=x-gm-message-state:from:to:cc:subject:date:message-id; bh=5f/8iEOjT79NwphG+VYeh3Qg4CCgiYJR+MqHUeF0vH8=; b=XO/0NlSMFvGyx7iRybc4PRODwJ4c+oNzeKivFl8GqjufU7omyCNAhPthU9zwLtgLYE S8FGmifL67tw9IZBhrllEHCWCGoUYwvdGrhBIEBVSzNjrVE5/LxofGPak3j3DPPWn3kU WBbb14dKgscDO910j7YI0+nr1FcREzRdFlHEplumOSJvd/abFmBIKawPK3JzFLcSPWjf IWW/vhvboj+JIlzoCVv8T1Zv8YVHhCEUbH2d7fQy/5FziYk3nqgDtD2VUxvo9t7YC6vo FEHM719+UEAeL4ygWAfqgFNfMfhhC1icFvaI7tkcLf2wLbI89SojJj97UA0qwGLVrAlZ r0qA== X-Gm-Message-State: ALoCoQlBQVsz02qa9X3g28vDZ/VIYsTMKPqgYKcsxootzhAoNOic+unhiL8KLPdKY8TZxFVQkCmXMVMIMuUWFNa3RG1vQmg8vUXNGAWbq6WalGlGO/p2Ex64YiKwIYQl+0AMIW9p7zShagFq6xUh/CaJDmdjgljQiMdEz4YcCEfcHPO5zY7PT4k= X-Received: by 10.112.140.196 with SMTP id ri4mr13396700lbb.55.1422529309181; Thu, 29 Jan 2015 03:01:49 -0800 (PST) X-Received: by 10.112.140.196 with SMTP id ri4mr13396671lbb.55.1422529308983; Thu, 29 Jan 2015 03:01:48 -0800 (PST) Received: from localhost ([195.238.92.241]) by mx.google.com with ESMTPSA id eb8sm2044810lbb.28.2015.01.29.03.01.47 (version=TLSv1.2 cipher=RC4-SHA bits=128/128); Thu, 29 Jan 2015 03:01:47 -0800 (PST) From: Oleksandr Dmytryshyn To: xen-devel@lists.xen.org, embedded-pv-devel@lists.xenproject.org Date: Thu, 29 Jan 2015 13:01:45 +0200 Message-Id: <1422529305-11410-1-git-send-email-oleksandr.dmytryshyn@globallogic.com> X-Mailer: git-send-email 1.9.1 Cc: Iurii Konovalenko , Keir Fraser , Ian Campbell , Tim Deegan , Ian Jackson , Jan Beulich Subject: [Embedded-pv-devel] [PATCH v6] sndif: add ABI for Para-virtual sound X-BeenThere: embedded-pv-devel@lists.xenproject.org X-Mailman-Version: 2.1.13 Precedence: list List-Id: List-Unsubscribe: , List-Post: List-Help: List-Subscribe: , MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Sender: embedded-pv-devel-bounces@lists.xenproject.org Errors-To: embedded-pv-devel-bounces@lists.xenproject.org This is ABI for the two halves of a Para-virtual sound driver to communicate with each to other.
