Okie Dokie. Check out: http://www.fsmware.com/xenofreebsd/5.3/ It only has the kernel, a compressed mdroot, and the config scripts that I use. The blocking issue discussed previously has not been fixed. I intend to fix it, but there are some infrastructure bits that take priority for me. Let me know how this works for you as soon as you try it out. -Kip> Kip: > > Any luck with that FreeBSD 5.3 kernel?

It is getting late and the 2.0-testing snapshot I''m running just locked up on me. I''ll look at it further tomorrow. Could you try looking at my freebsd config file?

Thank you very much for your work, Kip.
I successfully booted xenofreebsd from your source.
The following patch(obtained from NetBSD) seems to
fix the scheduling problem.

Thanks for patch and the heads up on the successful boot. I''ll apply the patch and update the posted tarball and kernel tonight. -Kip On Mon, 24 Jan 2005, Hidetoshi Shimokawa wrote:> Thank you very much for your work, Kip. > > I successfully booted xenofreebsd from your source. > The following patch(obtained from NetBSD) seems to > fix the scheduling problem. > > /\ Hidetoshi Shimokawa > \/ simokawa@FreeBSD.org > > diff -u -r /home/simokawa/xen/i386-xeno/i386-xeno/clock.c i386-xeno/i386-xeno/clock.c > --- /home/simokawa/xen/i386-xeno/i386-xeno/clock.c Mon Jan 24 10:36:19 2005 > +++ i386-xeno/i386-xeno/clock.c Mon Jan 24 16:58:31 2005 > @@ -502,3 +502,10 @@ > /* our adjusted time offset in microseconds */ > return edx; > } > + > +void > +idle_block(void) > +{ > + if (HYPERVISOR_set_timer_op(processed_system_time + NS_PER_TICK) == 0) > + HYPERVISOR_block(); > +} > diff -u -r /home/simokawa/xen/i386-xeno/i386-xeno/machdep.c i386-xeno/i386-xeno/machdep.c > --- /home/simokawa/xen/i386-xeno/i386-xeno/machdep.c Mon Jan 24 10:36:19 2005 > +++ i386-xeno/i386-xeno/machdep.c Mon Jan 24 17:50:25 2005 > @@ -140,6 +140,7 @@ > #include <machine/hypervisor.h> > #include <machine/xenfunc.h> > #include <machine/xenvar.h> > +#include <machine/xen_intr.h> > > void Xhypervisor_callback(void); > void failsafe_callback(void); > @@ -903,8 +904,13 @@ > */ > __asm __volatile("sti; hlt"); > #endif > +#if 0 > enable_intr(); > HYPERVISOR_yield(); > +#else > + idle_block(); > + enable_intr(); > +#endif > } > > /* > diff -u -r /home/simokawa/xen/i386-xeno/include/xen_intr.h i386-xeno/include/xen_intr.h > --- /home/simokawa/xen/i386-xeno/include/xen_intr.h Mon Jan 24 10:36:19 2005 > +++ i386-xeno/include/xen_intr.h Mon Jan 24 17:48:55 2005 > @@ -44,6 +44,7 @@ > extern void irq_suspend(void); > extern void irq_resume(void); > > +extern void idle_block(void); > > > #endif /* _XEN_INTR_H_ */ > > > At Sun, 23 Jan 2005 18:25:25 -0800 (PST), > Kip Macy wrote: > > > > For those interested I''ve uploaded a source tarball and copied in > > updated directions. > > > > > > -Kip > > > > > > > > On Sun, 23 Jan 2005, Derrik Pates wrote: > > > > > Kip Macy wrote: > > > > It looks like apache had gone out to lunch.

I tried booting your FreeBSD 5.3 kernel and mdroot on a P4 Celeron system here in my office running Xen (2.0.1, fyi); the kernel fired right up, mounted root, and came to a login: prompt. The system that was having problems is a dual Opteron 242 with 1 GB of RAM (it''s an HP DL145, specifically). If you''d like to log into the machine directly and see if you can figure anything out, please contact me off-list, and we''ll make arrangements; I''d like to see this work, but obviously the not-booting thing is kind of a downer. :) -- Derrik Pates demon@devrandom.net ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

My test machines are all, with the exception of an old dual PIII from Dell, dual Opteron 242s from Penguin Computing.

Well dandy. I''ve modified my config to mirror yours _exactly_ and it boots just fine. So make sure you''re running the latest 2.0-testing snapshot follow up with me when you the chance. -Kip> It seems to be related to the host system.

It is a chunk of work. You have to heavily modify pmap.c, replace all privileged operations with the corresponding xen operations, and port over the clock, block, and network device drivers. -Kip On Mon, 24 Jan 2005, Dave Feustel wrote:> Is there any chance of this or should I just wait for > Intel''s Vanderpool or AMD''s equivalent? >------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

After restarting, I tried starting the FreeBSD kernel inside a Xen domain; the result is currently the same. I''ll check the BIOS settings and see if, perhaps, there''s something relevant, but at this point, I''m still guessing it''s something about this machine. I''m not sure what though. -- Derrik Pates demon@devrandom.net ------------------------------------------------------- This SF.Net email is sponsored by: IntelliVIEW -- Interactive Reporting Tool for open source databases.

Funny you should ask. I just updated libxc to work with xen''s current context representation (previously I could just copy cpu_ctxt out and everything worked, but just prior to the change most of the register contents were wrong). I''ll try to get everything posted within the hour. One observation - I can''t comment on 64MB, but FreeBSD 5.x doesn''t do an adequate job of managing its memory to stay up with 32MB or less. -Kip On Tue, 25 Jan 2005, Hidetoshi Shimokawa wrote:> I have experianced strange lockups sometimes. > In that case, ''xm list'' shows no state for freebsd. > (usually it is blocked) > > Name Id Mem(MB) CPU State Time(s) Console > Domain-0 0 59 0 r---- 990.1 > freebsd.sample 2 64 0 ----- 547.6 9602 > > I''d like to analyze this problem using debugger. > I found gdbserver binary in your web site but it seems old and > to require old libraries.
