Hi Daniel,
> -----Original Message-----
> Subject: [PATCH v1 00/18] Hyperlaunch
With the adjustments that I suggested in other messages, this patch builds and
boots for me on x86 (including a device tree with a domU). I will continue to
poke around and see if I discover any other rough edges.
One strange behavior I see is that xen fails to start the Dom0 kernel on a warm
reboot. I'm using qemu_system_x86 with the KVM backend to test out the patch.
After starting qemu, xen will boot correctly only once. If I attempt to reboot
the virtual system (through the 'reboot' command in dom0 or the 'system_reset'
qemu monitor command) without exiting/starting a new qemu process on the host
machine, xen panics while booting after printing this:
(XEN) *** Building Dom0 ***
(XEN) Dom0 has maximum 856 PIRQs
(XEN) *** Constructing a PV Dom0 ***
(XEN) ELF: not an ELF binary
(XEN)
(XEN) ****************************************
(XEN) Panic on CPU 0:
(XEN) Could not construct domain 0
(XEN) ****************************************
This happens with the BUILDER_FDT config option on and off, and regardless of
what dtb (if any) I pass to xen. I don't see this behavior if I switch back to
xen's master branch.
Hopefully that explanation made sense. Let me know if I can provide any further
information about my setup.
Thanks,
Jackson
Also, I apologize that my last messages included a digital signature. Should be
fixed now.
