[PATCH 0/4] xen/arm: guest SMP support
Hi all,
this small patch series implement guest SMP support for ARM, using the
ARM PSCI interface for secondary cpu bringup.
Stefano Stabellini (4):
xen/arm: basic PSCI support, implement cpu_on
xen/arm: support for guest SGI
xen/arm: support vcpu_op hypercalls
xen: move VCPUOP_register_vcpu_info to common code

Spurious Interrupts on guest OS
...rupts and is not able to complete servicing the original virtual timer interrupt.
If I disable nesting (i.e. do not re-enable IRQs in my service routine), everything works as expected which makes me wonder if the spurious interrupts are related to the virtual timer. I tried adding a debug print in vgic_vcpu_inject_irq to see if xen was injecting some high priority interrupt but found that xen only injects a single virtual timer PPI.
Has anyone seen this behavior or has suggestions on how to debug this problem further ?
Thanks,
Ashish

[PATCH v2 00/14] xen: arm: 64-bit guest support and domU FDT autogeneration
I''ve addressed all (I think/hope) of the review comments.
The main change is to expose the guest virtual platform (e.g. memory
layout and interrupt usage etc) to the toolstack via the public
interface. This is then used during FDT generation. I have just codified
the current defacto standard layout, it''s probably not the best layout
but any change can be a separate patch/series.

[PATCH v6 00/16] xen: arm: 64-bit guest support and domU FDT autogeneration
Biggest change is to switch the new DTB node to /xen-core-devices
instead of /xen at Stefano''s request.
I also dropped the few patches title HACK etc which weren''t supposed to
be there and fixed up some bits and pieces which folks commented on.
George, WRT the freeze I think this is functionality which we cannot
ship Xen 4.4 without. The impact is entirely constrained to the

[PATCH v3] arm: support fewer LR registers than virtual irqs
If the vgic needs to inject a virtual irq into the guest, but no free
LR registers are available, add the irq to a list and return.
Whenever an LR register becomes available we add the queued irq to it
and remove it from the list.
We use the gic lock to protect the list and the bitmask.

[PATCH v3 00/46] initial arm v8 (64-bit) support
This round implements all of the review comments from V2 and all patches
are now acked. Unless there are any objections I intend to apply later

[PATCH 00/45] initial arm v8 (64-bit) support
First off, Apologies for the massive patch series...
This series boots a 32-bit dom0 kernel to a command prompt on an ARMv8
(AArch64) model. The kernel is the same one as I am currently using with
the 32 bit hypervisor
I haven''t yet tried starting a guest or anything super advanced like
that ;-). Also there is not real support for 64-bit domains at all,
although in one or two places I
