Thanks for the feedback. Sounds like I can try the same th= ing using Windows CE. How does FreeRTOS boot? From what I can see online it= uses DOS to boot, is how you have used it with Xen? Windows CE uses a dos = bootable drive to run a program named biosloader which loads the OS image w= hen the board is powered on after BIOS runs. Does FreeRTOS boot in a simila= r manner? If so I can look into how to do the same for Windows CE as you ha= ve for FreeRTOS...

Hello,

I will give regular Xen a try be= fore attempting RT Xen. I do not need any I/O to be deterministic, only the= ethernet ports need to be high priority (I am running an industrial ethern= et protocol on it). If I can assign a single core to Windows CE ans well as= dedicate an ethernet port to this core and OS, leaving the rest of the boa= rd for Linux non RT (remaining 3 cores and other peripherals) that is good = enough for me. I will investigate this next week when I return to my lab an= d update with any results (hopefully Xen isn't too difficult to boot up= on my Baytrail board with E3845 processor).

Thank= s,
Emir

So, I know nothing about Windows CE and how it's loaded.

In general, you can boot and use as *pure* HVM Xen guest any unmodified
operating system. Whether it will run well, it's another pair of hands<= br> (and that is the case with every hypervisor, actually)

In fact, while CPU is probably going to be fine, for IO, having some
kind of paravirtualization in place would be desirable. And to achieve
that, you need the guest to support it, e.g. via specific drivers.
These drivers exists for Windows, but I've no idea whether they work on=
CE too.

However, maybe you can just statically assign (by means of what we call
"PCI passthrough") the device that you need high performance from= to
your WinCE guest, in which case the lack of paravirt IO would not be an
issue...

In summary, it's hard to tell, until someone tries. :-/

People on this list have been working on using both QNX and Android = as
Xen guest, but I don't personally know the exact status of this.

There also has been a port of FreeRTOS (although, on ARM):
http://www.xen= project.org/directory/directory/projects/240-GaloisInc-FreeRTOS-Xen.html

That's a very interesting use case, and Xen is certainly capable= of
making it happen, if you can work out the issues above.

Things and features you may be interested in looking at are vcpu
pinning and/or vcpu hard and soft affinity, cpupools, and the RTDS
scheduler. Do ask about them either here or on the xen-users mailing
list (and keep me in Cc).

Hello,

I will give regular Xen a try be= fore attempting RT Xen. I do not need any I/O to be deterministic, only the= ethernet ports need to be high priority (I am running an industrial ethern= et protocol on it). If I can assign a single core to Windows CE ans well as= dedicate an ethernet port to this core and OS, leaving the rest of the boa= rd for Linux non RT (remaining 3 cores and other peripherals) that is good = enough for me. I will investigate this next week when I return to my lab an= d update with any results (hopefully Xen isn't too difficult to boot up= on my Baytrail board with E3845 processor).

Thank= s,
Emir

So, I know nothing about Windows CE and how it's loaded.

In general, you can boot and use as *pure* HVM Xen guest any unmodified
operating system. Whether it will run well, it's another pair of hands<= br> (and that is the case with every hypervisor, actually)

In fact, while CPU is probably going to be fine, for IO, having some
kind of paravirtualization in place would be desirable. And to achieve
that, you need the guest to support it, e.g. via specific drivers.
These drivers exists for Windows, but I've no idea whether they work on=
CE too.

However, maybe you can just statically assign (by means of what we call
"PCI passthrough") the device that you need high performance from= to
your WinCE guest, in which case the lack of paravirt IO would not be an
issue...

In summary, it's hard to tell, until someone tries. :-/

People on this list have been working on using both QNX and Android = as
Xen guest, but I don't personally know the exact status of this.

There also has been a port of FreeRTOS (although, on ARM):
http://www.xen= project.org/directory/directory/projects/240-GaloisInc-FreeRTOS-Xen.html

That's a very interesting use case, and Xen is certainly capable= of
making it happen, if you can work out the issues above.

Things and features you may be interested in looking at are vcpu
pinning and/or vcpu hard and soft affinity, cpupools, and the RTDS
scheduler. Do ask about them either here or on the xen-users mailing
list (and keep me in Cc).

Dario

Yes. Definitely! Try Xen first and then try the RTDS scheduler on Xen; Then, if RTDS scheduler does not satisty your requirement, which I don't think so, let me know and try RT-Xen. :-) Looking forward to hearing your good news! :-D Best, Meng > > On Tue, Feb 9, 2016 at 3:28 PM, Dario Faggioli > wrote: >> >> Hi, >> >> On Mon, 2016-02-08 at 09:59 -0800, Emir Elkholy wrote: >> > Currently we boot Windows CE from a dos bootable drive using a >> > program called biosloader on our x86 Baytrail board (Intel).

Yes. Definitely! Try Xen first and then try the RTDS scheduler on Xen; Then, if RTDS scheduler does not satisty your requirement, which I don't think so, let me know and try RT-Xen. :-) Looking forward to hearing your good news! :-D Best, Meng > > On Tue, Feb 9, 2016 at 3:28 PM, Dario Faggioli > wrote: >> >> Hi, >> >> On Mon, 2016-02-08 at 09:59 -0800, Emir Elkholy wrote: >> > Currently we boot Windows CE from a dos bootable drive using a >> > program called biosloader on our x86 Baytrail board (Intel).

Hi folks,

GSoc mentor organisation = applications are opening and as such we need to get our project list = into shape: the current list of projects are at http://wiki.xenproject.org/wiki/Xen_Development_Projects = and https://github.com/mirage/mirage-www/wiki/Pioneer-Projects<= /div>

The = application deadline is Feb 19th, by which we need to have a good list = of projects.

I = also wanted to address some challenges we had around Hypervisor projects = and necessary hardware and track that in the GSoc landing page, which I = will put together based on conversations with mentors

So what we need = is:
a) Weed out any old and stale projects (of = which we have a few)
b) Add some new ones, if = appropriate

I = will also need a co-administrator for the GSoC application

Hi all,

I will be chasing owners of projects to see whether = these are still applicable. And of course new projects are also welcome. = Please add them to the respective pages, or propose them against this = thread.

Also, = for Hypervisor projects, I created http://wiki.xenproject.org/wiki/Outreachy/Hypervisor w= hich still has to be populated based on suggestions from past mentors. = What we agreed on, is to add
a) Some blurb on HW = recommendations and how to check and then to get back to the project = owner with a log to make sure the applicant has the hardware to work on = the correct project
a.1) What is unresolved due to = uncertainty of general viability and debugging issues, is whether we = should recommend nested virt as a development environment (either = locally, or in a VM that the project could get for an = applicant) 
b) A test that checks whether an = applicant has been able to build xen from source and run xen: the idea = is to ask them to insert a debug statement into the code and then = provide the log as proof. This seems to have been one of the big hurdles = for many applicants, that have struggled

Hi folks,

GSoc mentor organisation = applications are opening and as such we need to get our project list = into shape: the current list of projects are at http://wiki.xenproject.org/wiki/Xen_Development_Projects = and https://github.com/mirage/mirage-www/wiki/Pioneer-Projects<= /div>

The = application deadline is Feb 19th, by which we need to have a good list = of projects.

I = also wanted to address some challenges we had around Hypervisor projects = and necessary hardware and track that in the GSoc landing page, which I = will put together based on conversations with mentors

So what we need = is:

b) Add some new ones, if = appropriate

I = will also need a co-administrator for the GSoC application

Best Regards

In addition, you may have seen that Ian Campbell recently transferred maintainer-ship for many components to other community members (see http://bit.ly/1RnM8JP). This means that Ian will take a much less active role within the project in the future. First and foremost, the remaining committers and the Xen Project Advisory Board would like to thank Keir, Tim and Ian for serving the Xen Project community and their manyfold and diverse contributions. Given, that as a project, we have found it difficult to promote contributors to maintainer and committer roles in the past, the remaining group of committers felt that we should use a more formal appointment process to successions and succession planning and have asked me to organise this process. Taking a longer term view, the committers also felt that we should not restrict the appointment process to replacing committer positions only, but to consider additional committer positions based on merit and to also include new maintainer nominations. Thus, to fill these positions, we are soliciting nominations. To nominate yourself or someone else within the community, please send e-mail to appointments@xenproject.org with one of the following subject lines: - "Maintainer Nomination of [name]" - "Committer Nomination of [name]" Nominees will of course be asked, privately, whether they would be willing to serve, if they have been nominated by someone else. Please provide contact details (at least the full name and e-mail address of nominee) in the body of the e-mail and describe why the nominee would be a good fit a maintainer and/or committer. The body of the nomination should list technical knowledge that is needed to be a maintainer and/or committer and highlight core areas of expertise. In addition, we are also interested in specific instances, where the nominee showed communication and open source leadership qualities. For example: * Was able to help resolve disagreements, both technical and non- technical, which you were a party to or observer of. * Was able to contribute to improve quality and architectural consistency across several components within the Hypervisor * Has been involved in coordinating the activities of several community members * Has led or driven technical initiatives or larger scale feature development within the community * Has mentored and encouraged newcomers to the community * Has represented the project or aspects of it (e.g. via talks, blog posts, ...) * Has shown other communication and open source leadership qualities Being a maintainer and/or committer does require a time commitment. Nominees should be able to follow e-mail discussions on xen-devel@ on an ongoing basis and respond within a couple of days so that discussions progress. Committers should ideally be able to spend a minimum of 4-5 days working on the project per month. For maintainers, the time requirement is likely less. We anticipate starting our selection process according to the following rough time-table. Today: Public call for nominations for new committers and maintainers (self-nominations and 3rd-party nominations both welcome) March 11: Closing date for nominations up to March 30: We email non-self-nominated nominees in private to ask them to confirm whether they are willing to act as nominees. We will also discuss with all nominees, time commitment and other possible questions (from both nominees and existing committers), related to the proposed nominations. March 30: We conduct a formal vote to ratify nominations April 6: We publish the new maintainers and committers (we may do this earlier) Note that we have identified some issues in our governance, such as whether we need to elect a new project lead or whether we introduce a committee to steer the project instead, alongside other issues.

In addition, you may have seen that Ian Campbell recently transferred maintainer-ship for many components to other community members (see http://bit.ly/1RnM8JP). This means that Ian will take a much less active role within the project in the future. First and foremost, the remaining committers and the Xen Project Advisory Board would like to thank Keir, Tim and Ian for serving the Xen Project community and their manyfold and diverse contributions. Given, that as a project, we have found it difficult to promote contributors to maintainer and committer roles in the past, the remaining group of committers felt that we should use a more formal appointment process to successions and succession planning and have asked me to organise this process. Taking a longer term view, the committers also felt that we should not restrict the appointment process to replacing committer positions only, but to consider additional committer positions based on merit and to also include new maintainer nominations. Thus, to fill these positions, we are soliciting nominations. To nominate yourself or someone else within the community, please send e-mail to appointments@xenproject.org with one of the following subject lines: - "Maintainer Nomination of [name]" - "Committer Nomination of [name]" Nominees will of course be asked, privately, whether they would be willing to serve, if they have been nominated by someone else. Please provide contact details (at least the full name and e-mail address of nominee) in the body of the e-mail and describe why the nominee would be a good fit a maintainer and/or committer. The body of the nomination should list technical knowledge that is needed to be a maintainer and/or committer and highlight core areas of expertise. In addition, we are also interested in specific instances, where the nominee showed communication and open source leadership qualities. For example: * Was able to help resolve disagreements, both technical and non- technical, which you were a party to or observer of. * Was able to contribute to improve quality and architectural consistency across several components within the Hypervisor * Has been involved in coordinating the activities of several community members * Has led or driven technical initiatives or larger scale feature development within the community * Has mentored and encouraged newcomers to the community * Has represented the project or aspects of it (e.g. via talks, blog posts, ...) * Has shown other communication and open source leadership qualities Being a maintainer and/or committer does require a time commitment. Nominees should be able to follow e-mail discussions on xen-devel@ on an ongoing basis and respond within a couple of days so that discussions progress. Committers should ideally be able to spend a minimum of 4-5 days working on the project per month. For maintainers, the time requirement is likely less. We anticipate starting our selection process according to the following rough time-table. Today: Public call for nominations for new committers and maintainers (self-nominations and 3rd-party nominations both welcome) March 11: Closing date for nominations up to March 30: We email non-self-nominated nominees in private to ask them to confirm whether they are willing to act as nominees. We will also discuss with all nominees, time commitment and other possible questions (from both nominees and existing committers), related to the proposed nominations. March 30: We conduct a formal vote to ratify nominations April 6: We publish the new maintainers and committers (we may do this earlier) Note that we have identified some issues in our governance, such as whether we need to elect a new project lead or whether we introduce a committee to steer the project instead, alongside other issues. We aim to resolve these issues *after* new maintainers and committers have been elected. If you do have any questions related to the process, feel free to reply to this thread. In addition, if you want to nominate someone else or yourself but are not sure, feel free to send your question to appointments@xenproject.org preceded by "Question:" in the subject line.
