I think Xen can
impose lid to the guest firmware. Things will be a little simpler.
I don't catch you, Could you explain in more detail?
I think lid_2_vcpu is almost useless. Like in paravirtualized, vcpuid should
be simply extracted from lid.

this patch cleans up all remaining warnings.
-Werror and -Wno-uninitialized are added for make no_warns=y
Two comments:
I disable -Wuninitialized. The reason is simple: this warning can be falsly
triggered and thus depends on compiler version. I think it will be a
nightmare to enforce it

After enabling dom0_vp mode, we lost domain0's VGA console, and we have
to connect it through network or serial console.
The reason is that VGA frame buffer(0xa-0xc) was set to
conventional
memory not IO in dom0's p2m table. Attached patch fixes it.
Thanks

Hi Alex,
We are using tiger4 platform. I didn't find md about space:
0xa-0xc in efi memmap, maybe it was assumed EFI_MEMORY_MAPPED_IO in

MDs efi provides. Seems your platform has VGA console. So this

This patch tries to check MD's overlap and tries not to assign
page to non conventional area.
Maybe you may want to apply this patch before VGA-related modifications.

There is no protection to IPI.
Is it O.K? Does the use of IPI cause race?
Do you mean below code?
