Yes: Is another 1-2 problem[s], but is problem[s]:


==
TO All:

Please, replace
CONFIG_PARAVIRT_GUEST=y
with
CONFIG_HYPERVISOR_GUEST=y
==

==
Is good?

CONFIG_PARAVIRT_GUEST in arch/ia64 :

./linux-3.10-rc1/arch/ia64/include/asm/native/
inst.h
./linux-3.10-rc1/arch/ia64/configs/
xen_domu_defconfig
./linux-3.10-rc1/arch/ia64/include/asm/
hw_irq.h
iosapic.h
paravirt.h

==
. . .
#ifdef CONFIG_PARAVIRT_GUEST

#define PARAVIRT_HYPERVISOR_TYPE_DEFAULT 0
#define PARAVIRT_HYPERVISOR_TYPE_XEN 1
. . .

Comments ?

This is only an issue if hyperv or vmware balloon is designed to work on
ia64.

However, both hyperv and vmware balloon depend on X86 so they are never
enabled on ia64.

So the way I see it, it doesn't matter.

Tony, what's your take on this - CONFIG_PARAVIRT_GUEST is
present in ia64 and I recently changed the Kconfig symbol to
CONFIG_HYPERVISOR_GUEST on x86. I can fix it for correctness but is
hyperv and vmware balloon even attempted on ia64?

Btw, it depends on BROKEN on ia64 so I'm already sceptical.

Thanks.

We added "BROKEN" in the middle of last year because this was
kicking out too many errors in Fengguang's zero-day build system.
Essentially all this stuff has been unmaintained for a while now,
and it doesn't seem that anyone is going to start caring about it
again.
