Hello, Has anyone tried to get Xen 2.0.7 booting on a VIA EPIA board with a VIA C3 CPU? I know some of the EPIA mainboards have a CPU with "features" (4kb pages and no cmov instruction) that require the patch Adam Sulmicki put together for 2.0.0 and 2.0.1 (http://lists.xensource.com/archives/html/xen-devel/2004-12/txt8D0L7RWimG.txt), and I have managed to patch, compile and boot a NetBSD dom0 sucessfully with this version. However, I would really like to try and get 2.0.7 going, so I''ve attempted to apply the original patch where it still seemed appropriate. The patch does manage to get me some output from Xen as it boots (which is a great step forward from the immediate reboot without it), however the whole thing halts with "(XEN) Unknown interrupt" just after " XEN) System RAM: 509MB (521852kB)". With a few well placed printk''s I was able to determine that the halt was happening inside init_frametable() in arch/x86/memory.c, at the point where it calls memset(frame_table, 0, frame_table_size). Unfortunately my C & ASM skills being what they are (i.e not great) I''m making slow progress. Anyone more accomplished been there and done this, or can lend a hand?

But maybe there are other glitches, as I would assume from my (bad) 3 years experience with this hardware.> Unfortunately my C & ASM skills being what they are (i.e not great)Same here;-) Helmut Wollmersdorfer _______________________________________________ Xen-devel mailing list Xen-devel@lists.xensource.com http://lists.xensource.com/xen-devel

A few weeks ago I changed the mainboard (had a blown condensator), but after 2 weeks it again freezed. Today I will change memory as a last trial. As a result I have now parts for a third EPIA, which can be expected to run some days - good enough for testing XEN kernels;-) Maybe you know the lock-up thread at http://forums.viaarena.com/messageview.aspx?catid=28&threadid=60131&enterthread=y with funny esoteric solutions.

Not Xen? If you are using Xen, which version is it? Did you patch it?No, I am not using Xen on the VIAs. But Xen would be an alternative to my configuration (vserver-guests on a DRBD device in a heartbeat cluster - see my HOWTO on http://linux-vserver.org/Vserver+DRBD). In reverse you could use vserver instead of Xen, but this will not work with non-Linux guests.

I''m with you as well. Tried desperately to transfer Adam''s patch to xen 2.0.6 and got the exact same "unknown interrupt" error. Xen memory management has been completely rewritten since xen 2.0.1. It seems that we definitely need some developer with asm skills and deep insight into xen''s architecture (both of which I do not have) to enable 4kb pages support for xen 2.0.6 onwards. It should be worth it, since it could open Xen to a wider usage besides the high end server field. VIA Samuel C3 allows reliable low-energy, fanless operation. With xen and such a mainboard, you can host groupware, proxy and firewall services on one single fanless computer, each of these services running completely separated in three xen domains. This is an ideal solution for small workgroups or family offices. We use xen 2.0.1 with Adam''s patch for that purpose. regards> I''m on the same boat with a VIA Samuel C3.

It''s clocked at 1Ghz, and has Dual LAN on board, so I''m expecting it to offer additional flexibility for my Xen environment. I think the CPU still only consumes around 14 watts at full load, so the whole thing will still offer excellent power efficiency. I''ll report back on my progress with this board later in the week.

Yeah I could not agree with you more. With power consumption becoming more of a hot topic I believe that processor such as the C3 will become even more relevant... even for production environments. - raf On Mon, 2005-10-03 at 15:02 +0200, Harald Brass wrote:> I''m with you as well.

I tried xen (2.0.6 stable and 3.0 testing with linux as dom0) with a 1 GHz fanless VIA MS10000E mainboard. It has a Nehemiah core and boots under xen without need for patches. But I had other problems with that mainboard. On a "shutdown -r now" the board shuts down and freezes (instead of rebooting) - not good for the intended purpose as groupware server / proxy / firewall. This problem should not be xen related as the same happened under unmodified linux kernel. Please inform me if your experience with your new board are better. I personally prefer the older 500 MHz VIA Samuel C3. It does not have this reboot problem and consumes even less power (but has its 4kb and cmov restrictions). regards> I heard reports that the C3 Nehemiah core in the (EPIA M10000 etc) is > a more fully rounded i686, supporting both CMOV and the page sizes Xen > expects to use, so I''ve orded a CL10000 board.

Chris, I have a Samuel 2 on a ASUS barebone: [rafael@butters ~]$ cat /proc/cpuinfo processor : 0 vendor_id : CentaurHauls cpu family : 6 model : 7 model name : VIA Samuel 2 stepping : 3 cpu MHz : 800.473 cache size : 64 KB fdiv_bug : no hlt_bug : no f00f_bug : no coma_bug : no fpu : yes fpu_exception : yes cpuid level : 1 wp : yes flags : fpu de tsc msr cx8 mtrr pge mmx 3dnow bogomips : 1581.05 As of a month ago, neither 2x or 3x would run but I''m going to try the 3.x series again this week to see what happens. The samuel2 AFAIK, has the cmov and 4k limitation. - raf On Mon, 2005-10-03 at 21:09 +0200, Harald Brass wrote:> I tried xen (2.0.6 stable and 3.0 testing with linux as dom0) with a 1 > GHz fanless VIA MS10000E mainboard.
