Hi all,
I install Xen 4.8 on Ubuntu 17.04 (kernel is updated to 4.12). But I found only
1 CPU was detected.
I thought it is caused by some BIOS settings, so I enabled x2APIC in BIOS,
unfortunately, Linux hangs during booting after printing "Loading initial
ramdisk ...".
I have to disable x2AP

PVHv2 is always going to require the usage of memory in order to store
the p2m page tables, either when using hap or shadow.
Fix the condition so memory is reserved unconditionally when trying to
build a PVHv2 Dom0.

In order to support pvclock vdso on xen we need to setup the time
info page for vcpu 0 and register the page with Xen using the
VCPUOP_register_vcpu_time_memory_area hypercall. This hypercall
will also forcefully update the pvti which will set some of the
necessary flags for vdso. Afterwards we che
Right now there is only a pvclock_pvti_cpu0_va() which is defined
on kvmclock since:
commit dac16fba6fc5
("x86/vdso: Get pvclock data from the vvar VMA instead of the fixmap")
The only user of this interface so far is kvm. This commit adds a
setter function for the pvti page and moves pvclock_pvt
This file defines an ABI shared between guest and hypervisor(s)
(KVM, Xen) and as such there should be an correspondent entry in
MAINTAINERS file. Notice that there's already a text notice at the
top of the header file, hence this commit simply enforces it more
explicitly and have both peers notice
Hey,
This is take 4 for vdso for Xen. PVCLOCK_TSC_STABLE_BIT can be set starting Xen
4.8 which is required for vdso time related calls. In order to have it on, you
need to have the hypervisor clocksource be TSC e.g. with the following boot
params "clocksource=tsc tsc=stable:socket".

An access which crosses a page boundary is performed atomically by x86
hardware, albeit with a severe performance penalty. An important corner case
is when a straddled access hits two pages which differ in whether a
translation exists, or in net access rights.
