xen: event channel arrays are xen_ulong_t and not unsigned long

2013-02-20T13:45:07+00:00

On ARM we want these to be the same size on 32- and 64-bit.

This is an ABI change on ARM. X86 does not change.

xen/acpi: ACPI cpu hotplug

2013-02-20T03:02:29+00:00

This patch implement real Xen ACPI cpu hotplug driver as module.
When loaded, it replaces Xen stub driver.

For booting existed cpus, the driver enumerates them.
For hotadded cpus, which added at runtime and notify OS via
device or container event, the driver is invoked to add them,
parsing cpu information, hypercalling to Xen hypervisor to add
them, and finally setting up new /sys interface for them.

xen/acpi: ACPI memory hotplug

2013-02-20T03:02:26+00:00

This patch implements real Xen acpi memory hotplug driver as module.
When loaded, it replaces Xen stub driver.

When an acpi memory device hotadd event occurs, it notifies OS and
invokes notification callback, adding related memory device and parsing
memory information, finally hypercall to xen hypervisor to add memory.

xen: implement updated XENMEM_add_to_physmap_range ABI

2013-02-20T03:01:55+00:00

Allows for more fine grained error reporting. Only used by PVH and
ARM both of which are marked EXPERIMENTAL precisely because the ABI
is not yet stable

xen: arm: implement remap interfaces needed for privcmd mappings.

2012-11-29T14:00:19+00:00

We use XENMEM_add_to_physmap_range which is the preferred interface
for foreign mappings.

xen/acpi: Move the xen_running_on_version_or_later function.

2012-11-28T19:39:31+00:00

As on ia64 builds we get:
include/xen/interface/version.h: In function 'xen_running_on_version_or_later':
include/xen/interface/version.h:76: error: implicit declaration of function 'HYPERVISOR_xen_version'

We can later on make this function exportable if there are
modules using part of it. For right now the only two users are
built-in.

xen/acpi: Fix compile error by missing decleration for xen_domain.

Commit 92e3229dcdc80ff0b6304f14c578d76e7e10e226
("xen/acpi: ACPI PAD driver") adds a new function but forgets to
use the right header. Without it, we get:

xen/acpi: ACPI PAD driver

2012-11-26T20:07:19+00:00

PAD is acpi Processor Aggregator Device which provides a control point
that enables the platform to perform specific processor configuration
and control that applies to all processors in the platform.

This patch is to implement Xen acpi pad logic. When running under Xen
virt platform, native pad driver would not work. Instead Xen pad driver,
a self-contained and thin logic level, would take over acpi pad logic.

When acpi pad notify OSPM, xen pad logic intercept and parse _PUR object
to get the expected idle cpu number, and then hypercall to hypervisor.
Xen hypervisor would then do the rest work, say, core parking, to idle
specific number of cpus on its own policy.
