Resending again as it appears sourceforge website wont accept more than certain characters per line.

Subject: Re: [Embeddedxen-devel] Regarding DOMU Xen-ARM

Thanks Daniel for the reply.

I have directly downloaded Embedded Xen 2.1 from SourceForge. Can you please point me to git path? i couldn't find one.

Any issues with source forge code repository?

I have got basic DOMu working  without any drivers but simulated uart in Linux (for the busybox application)with some hacks. Basically
 i call
    local_flush_tlb_all();
    flush_cache_all();
in multiple places of devicemaps_init. For some reason, this solved the issue, Although i don't know how it got solved.

I am thinking the problem may be because of following
Basically in the code it clears Page table entry 0xffff0000, after that there is flush_cache_range and then my disable_IRQ, 
local_tlb_flush_all.  Now even though flush_cache_range clears cache , if interrupt occurs if TLB is valid it can populate 
the cache after TLB Walk.  However if TLB is not valid then it may hang. I am thinking solution can be to disable irq before 
we clear pagetable entry and reenable after we copy the vectors properly. I will try this sometime tomorrow.  
Does this theory make any logical sense?

1 more thing if i mail directly (of course will keep embeddedxen mailling list in CC)to your email id 
will it work?

Warm Regards,
Akshay

By the way, are you using the release from files available on Sourceforge or from git directly?

We strongly suggest that for now you are working with the last git source code.
We plan to make a new release (with tar.gz files) in the middle of the Year.

In the git version, we're doing nearly daily updates.

Well, even if you do not use hypercall at this stage, you need consistent vectors since some IRQs
previously configured by dom0 may occur (of course, if you disable IRQs, you should not have any problem).
That's why domU vectors are placed somewhere else in the memory.
Try to debug step-by-step the flush function to see what happens. It may well be a freeze after the local_flush_tlb_all()
at a point where IRQs get re-enabled...

Basically, you do not need any I/Os in domU since hardware access are under control of dom0.
Except for debug purposes, but it  mainly concerns UART.
So we can leave the mapped I/O as such in domU without doing any I/O mapping.

I hope it helps.

[Embeddedxen-devel] Regarding DOMU Xen-ARM

[akshay st <aks...@ya...>]

Hi,
I took Embedded Xen 2.1 sources for ARM, i am modifiying for my 
board, i could understand and bring up DOM0 without issues, However i 
have some doubts regarding DOMU w.r.t devicemaps_init(),
Here we wont
 clear oxFFFF0000 for high vectors assuming that during upcall ISR may 
come(Because of flush), However in my implementation i dont use XEN 
hyper calls For TLb/Cache flush , i take the same implementation as 
DOM0(which i guess it shd be ok?). Basically i keep devicemaps_init() 
implementation same as DOM0, With this when i run local_flush_tlb_all() 
Linux hangs, I have disabled IRQ's before using local_irq_disable(). I 
dont know why it hangs, Any pointers will be helpful.

1 more question on devicemaps_init
Why
 is the below commented on DOMu and not on DOM0, Does Xen Hypervisor 
populate any of this area? if so what does it do and can you please 
point me to the code?
#if 0
    for (addr = VMALLOC_END; addr < HYPERVISOR_VIRT_START; addr += PGDIR_SIZE)
        pmd_clear(pmd_off_k(addr));
#endif

Re: [Embeddedxen-devel] Can we run the embeddedxen on HTC Desire C?

[Krishna P. <pos...@gm...>]

Hi all,

HTC Desire C and HTC Desire HD have two different Chipsets.

Then the system_map will also change.

In that case you need to find a bootloader for HTC Desire C that fits the
Embedded Xen.

So you cannot use Embedded Xen on HTC Desire C.

Re: [Embeddedxen-devel] Can we run the embeddedxen on HTC Desire C?

[Colloud L. <lau...@he...>]

Hi Sujatha,

First, start with a simple hypervisor+dom0 image (no domU) as having a Guest domain complicates things a bit more. I will try and update the EmbeddedXEN wiki this week to provide more information on how to deploy on Desire HD.

To compile hypervisor+ dom0:
$ make PLATFORM=desireHD DOMAINS="linux-2.6.32-dom0"

Then for the boot.img, it could be one of many things.
In tools/htc/dhd, the script create_img_hd.sh needs to be adapted for your phone:

-          You need the ramdisk of your HTC Desire C

-          The RAM base address may be different on the HTC Desire C (BASE=0x04000000 on Desire HD)

-          The ramdisk offset from BASE may also be different on HTC Desire C (see tools/htc/image-utils/mkbootimg/mmkbootimg.c and adapt code accordingly l.142).

Thanks,

Laurent

Re: [Embeddedxen-devel] Pandaboard support

[Bornet R. <rom...@he...>]

Hi Bala,

Please always post to the mailing-list address (emb...@li...) and not to individuals. It can always help others to have a view in issues of other developers.
Now regarding your particular issue with Pandaboard...

> Greetings!  I have tried to port HTC desire HD in pandaboard already. It shows couple of errors while doing the final step. I mean making hypervisor, dom0 and domu files:
> 1. syntax mismatching with parenthesis( )
> 2. Respective /vmlinz is not present.
>  can you give me any suggestion over that?

Without a more detailed problem description, it will be hard to help you. You can perhaps send a log of the build output which gives more information on the location and type of error. 
> 1. syntax mismatching with parenthesis( )
Should be rather easy to solve by analyzing where and why this happens. This kind of errors typically come with conditionnal compilation (#if/#ifdef) and it is possible that when compiling for Pandaboard you activate code that was not activated for Desire or other platforms. Have a look at the location of the error in the code. You should find quickly where there is/are problem/s with parenthesis.

> 2. Respective /vmlinz is not present.
If you have compilation issues, the binaries won't be generated... So first fix the build issues then we can tackle down the Linux (dom0/U) images problem.

How did you patch the kernel for Pandaboard ? Did you paravirtualize everything needed for Panda ? 
You can have a look at the adaptations done for HTC Desire HD in this commit for example: http://sourceforge.net/p/embeddedxen/code/ci/cb104712cccd5c7c8c07583746707e3255c28915/ 
This is the inclusion of Desire HD (2.6.32-dom0) into EmbeddedXen.

And the patch: http://sourceforge.net/p/embeddedxen/code/ci/6358dd0031e04f2a6305ac0323af7af9057452e8/tree/tools/patches/linux-2.6.32-dom0.patch
This is the patch which must be applied on top of original 2.6.32 HTC kernel. These resources should give you all necessary information you need to port EmbeddedXen on Panda.
The original Desire HD kernel can be downloaded from http://www.htcdev.com/devcenter/downloads > Filter: 
Device: HTC Desire HD
Android version: v2.2 
Kernel source code > Find files.

The kernel we took as a base is the latest one in the list
Desire HD - N/A - N/A - N/A - 2.6.32 - v2.2 - 86.6 MB --> http://dl4.htc.com/RomCode/Source_and_Binaries/ace_2.6.32_g5ed1769.tar.gz

Please note that we do not already support SMP with EmbeddedXen. It is on our roadmap but still not implemented. For the Panda, you'll have to disable SMP and use only one core for now.

   Romain

Dear daniel,

                  Greetings!  I have tried to port HTC desire HD in pandaboard already. It shows couple of errors while doing the final step. I mean making hypervisor, dom0 and domu files:
                1. syntax mismatching with parenthesis( )
                2. Respective /vmlinz is not present.

    can you give me any suggestion over that?

[Embeddedxen-devel] EmbeddedXen: dom0 and domU running on HTC Desire HD on YouTube

[Bornet R. <rom...@he...>]

Hi,

We just uploaded our first video on the EmbeddedXen Youtube channel: http://www.youtube.com/user/embeddedxen

The video is demonstrating EmbeddedXen running on a HTC Desire HD with an Android dom0 and SqueezeOS domU.
The video can be viewed here: http://youtu.be/ErLZQE5ZI7U

Feel free to post comments and/or questions on the mailing-list or directly in the comments section of the video.

    Romain

Re: [Embeddedxen-devel] installing other guest on domU

[Bornet R. <rom...@he...>]

Hi Mabel,

>> Is it possible to install other guests other than Squeezebox on domU? If yes , how?
SqueezeOS is currently the only guest (kernel + rootfs) we support on domU. We are currently working on porting other Linux distributions/stacks on domU and will post updates on SourceForge when we will have a working environment.
We are also planning to port other OS to run on domU but this will come in a second step.

>> Do xm commands work in dom0 or domU?
xm commands and other userspace utilities are not supported in EmbeddedXen. Since we do not create domains dynamically and do not already support migration and dynamic control over domains (suspend/save/resume/restore) we don't need such tools. We will perhaps sometimes support some of these tools or a subset of their functionality (for guest migration for example) but we have no precise roadmap for these features.

    Romain

[Embeddedxen-devel] Fixed the bug when only dom0 is running

[Rossier D. <Dan...@he...>]

Hi,

The problem which appears when only dom0 is running (without domU) has been fixed.
Grant table was referring to an unexisting number of foreign pages (of course ;-) during the init. Now, the grant table init is skipped when there is no domU.

The fix is available in git and will be put in the next release.

With EmbeddedXEN, both dom0 and domU are automatically loaded during the bootstrap (the hypervisor starts dom0 then domU).
Therefore, the two guest OSes run in parallel from the beginning. To have the focus on both domains in the QEMU/versatilev6 environment,
you can make use of ctrl+alt+1 and ctrl+alt+2 to switch between the two outputs; currently, domU uses the framebuffer while dom0 a serial line console only.
On QEMU/Goldfish, you can get the focus on domU by typing on the magnifier-key of your emulated Android terminal. Same on HTC desire HD.

> 
> Please can you make clear on what sort of xen comands would work here?

Since both domains run in parallel, there are no needs for additional commands. In the future, we will also have some facilities to
enable live migration of domU on other devices, but it is still at an infancy stage.

Cheers
Daniel

Hi Mabel Mary Joy,

I would like to be in loop, with respect to your question, as I wanted to
learn about it.

As far as I know, it has been patched with QEMU.
So, you can check that, in a separate console, about the rom loaded at
specific address etc.

Xen controls and monitors domU, collaborative with dom0.

[Embeddedxen-devel] How to monitor and control guests in embedded xen

[mabel m. j. <mar...@gm...>]

Hi

I was able to install and run the dom0 and domU of embeddedxen 2.0.
But I am still unclear on how to control and monitor the guests running on
domU.

Please can you make clear on what sort of xen comands would work here?
The normal xen commands fails in this case.
Is there any cheat sheet for the commands?
Any help would be appreciated.

EmbeddedXEN uses xenbus and xenstore in a different way (and much simpler) than the original XEN. A xenstore registry is dynamically created at the 
bootstrap of dom0, and access to this registry is based on the same mechanisms than XEN. However, there is no need for a user space daemon or similar
stuff  since everything is at the kernel level, in xen-guest subsystem.

I'm currently writing a paper about the architecture of EmbeddedXEN which will be published over the Year. I will keep the mailing list informed.

Coming to embedded xen,

Is there any chance that *xenstored* can be used for Inter-Guest
Communication [here dom0 - domU] in *embedded xen*?

Please Suggest!

Yeap, sorry for that; the starting guide did not mention really. I've updated the page. Please see:

I am sorry, I could not find a make command for the goldfish.

I could only find a make command for the versatile.

Can you please tell me, what the make command is for goldfish?

May I suggest you to download the 2.1 version and to try with that? 
Goldfish runs on my side. Just make sure you are using the right toolchain
(provided in tools/toolchain).

If you still have some trouble, give us the make command you do.

[Embeddedxen-devel] embeddedXEN 2.1: issues with symbolic links to xen-guest

[Rossier D. <Dan...@he...>]

Hi everyone,

I have just discovered a couple of issues in the just released EmbeddedXEN (2.1).

Actually, the symbolic links which are created during the build of dom0/U fails. I've modified the main Makefile so that
the links are created in the guest trees.

You can re-download the tarball embeddedxen-2.1-base.tar.gz and it should work.

Furthermore, there was a missing dir in drivers/net for the network backend driver in the linux-2.6.32-dom0.
You will find an updated version (still 2.1) in the embeddedxen-2.1-others-dom0 tarball.

Please note also that, at the moment, it is not possible to run only dom0 (without domU). You need to initiate a make command
with both dom0 and domU
(as example: make PLATFORM=versatilev6 DOMAINS="linux-2.6.26-dom0 fab4:linux-2.6.26-domU")

We apologize for these issues.

Kind regards
Daniel

[Embeddedxen-devel] EmbeddedXEN 2.1 Released.

[Rossier D. <Dan...@he...>]

Hi All!

EmbeddedXEN 2.1 has been released.

Along various bug fixes, this release brings about networking support for the following domains:

- linux-2.6.26-dom0
- linux-2.6.26-domU
- linux-2.6.32-dom0

Furthermore, various grant tables have been revisited in order to support shared foreign pages between dom0 and domU more efficiently (required for networking and block dev).

One of our major ongoing efforts are now on the port of Ubuntu-like distrib on domU in order to have Android and Ubuntu on HTC Smarphone as two real independent OS.
keep in touch!

Enjoy EmbeddedXEN 2.1!

Cheers
Daniel
