Pull Xen updates from Konrad Rzeszutek Wilk: - Add necessary infrastructure to make balloon driver work under ARM. - Add /dev/xen/privcmd interfaces to work with ARM and PVH. - Improve Xen PCIBack wild-card parsing. - Add Xen ACPI PAD (Processor Aggregator) support - so can offline/ online sockets depending on the power consumption. - PVHVM + kexec = use an E820_RESV region for the shared region so we don't overwrite said region during kexec reboot. - Cleanups, compile fixes. Fix up some trivial conflicts due to the balloon driver now working on ARM, and there were changes next to the previous work-arounds that are now gone. * tag 'stable/for-linus-3.8-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: xen/PVonHVM: fix compile warning in init_hvm_pv_info xen: arm: implement remap interfaces needed for privcmd mappings. xen: correctly use xen_pfn_t in remap_domain_mfn_range. xen: arm: enable balloon driver xen: balloon: allow PVMMU interfaces to be compiled out xen: privcmd: support autotranslated physmap guests. xen: add pages parameter to xen_remap_domain_mfn_range xen/acpi: Move the xen_running_on_version_or_later function. xen/xenbus: Remove duplicate inclusion of asm/xen/hypervisor.h xen/acpi: Fix compile error by missing decleration for xen_domain. xen/acpi: revert pad config check in xen_check_mwait xen/acpi: ACPI PAD driver xen-pciback: reject out of range inputs xen-pciback: simplify and tighten parsing of device IDs xen PVonHVM: use E820_Reserved area for shared_info

xen: arm: enable balloon driver

2012-11-29T12:59:14Z

The code is now in a state where can just enable it. Drop the *_xenballloned_pages duplicates since these are now supplied by the balloon code. Signed-off-by: Ian Campbell Acked-by: Stefano Stabellini Signed-off-by: Konrad Rzeszutek Wilk

xen/acpi: ACPI PAD driver

2012-11-26T20:07:19Z

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.

xen/generic: Disable fallback build on ARM.

2012-11-07T15:46:07Z

As there is no need for it (the fallback code is for older hypervisors and they only run under x86), and also b/c we get: drivers/xen/fallback.c: In function 'xen_event_channel_op_compat': drivers/xen/fallback.c:10:19: error: storage size of 'op' isn't known drivers/xen/fallback.c:15:2: error: implicit declaration of function '_hypercall1' [-Werror=implicit-function-declaration] drivers/xen/fallback.c:15:19: error: expected expression before 'int' drivers/xen/fallback.c:18:7: error: 'EVTCHNOP_close' undeclared (first use in this function) drivers/xen/fallback.c:18:7: note: each undeclared identifier is reported only once for each function it appears in .. and more [v1: Moved the enablement to be covered by CONFIG_X86 per Ian's suggestion] Signed-off-by: Konrad Rzeszutek Wilk

xen/hypercall: fix hypercall fallback code for very old hypervisors

2012-11-04T15:40:42Z

While copying the argument structures in HYPERVISOR_event_channel_op() and HYPERVISOR_physdev_op() into the local variable is sufficiently safe even if the actual structure is smaller than the container one, copying back eventual output values the same way isn't: This may collide with on-stack variables (particularly "rc") which may change between the first and second memcpy() (i.e. the second memcpy() could discard that change). Move the fallback code into out-of-line functions, and handle all of the operations known by this old a hypervisor individually: Some don't require copying back anything at all, and for the rest use the individual argument structures' sizes rather than the container's.

Pull ADM Xen support from Konrad Rzeszutek Wilk: Features: * Allow a Linux guest to boot as initial domain and as normal guests on Xen on ARM (specifically ARMv7 with virtualized extensions). PV console, block and network frontend/backends are working. Bug-fixes: * Fix compile linux-next fallout. * Fix PVHVM bootup crashing. The Xen-unstable hypervisor (so will be 4.3 in a ~6 months), supports ARMv7 platforms. The goal in implementing this architecture is to exploit the hardware as much as possible. That means use as little as possible of PV operations (so no PV MMU) - and use existing PV drivers for I/Os (network, block, console, etc). This is similar to how PVHVM guests operate in X86 platform nowadays - except that on ARM there is no need for QEMU. The end result is that we share a lot of the generic Xen drivers and infrastructure. Details on how to compile/boot/etc are available at this Wiki: http://wiki.xen.org/wiki/Xen_ARMv7_with_Virtualization_Extensions and this blog has links to a technical discussion/presentations on the overall architecture: http://blog.xen.org/index.php/2012/09/21/xensummit-sessions-new-pvh-virtualisation-mode-for-arm-cortex-a15arm-servers-and-x86/ * tag 'stable/for-linus-3.7-arm-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen: (21 commits) xen/xen_initial_domain: check that xen_start_info is initialized xen: mark xen_init_IRQ __init xen/Makefile: fix dom-y build arm: introduce a DTS for Xen unprivileged virtual machines MAINTAINERS: add myself as Xen ARM maintainer xen/arm: compile netback xen/arm: compile blkfront and blkback xen/arm: implement alloc/free_xenballooned_pages with alloc_pages/kfree xen/arm: receive Xen events on ARM xen/arm: initialize grant_table on ARM xen/arm: get privilege status xen/arm: introduce CONFIG_XEN on ARM xen: do not compile manage, balloon, pci, acpi, pcpu and cpu_hotplug on ARM xen/arm: Introduce xen_ulong_t for unsigned long xen/arm: Xen detection and shared_info page mapping docs: Xen ARM DT bindings xen/arm: empty implementation of grant_table arch specific functions xen/arm: sync_bitops xen/arm: page.h definitions xen/arm: hypercalls ...

USB EHCI/Xen: propagate controller reset information to hypervisor

2012-09-18T16:20:48Z

Just like for the in-tree early console debug port driver, the hypervisor - when using a debug port based console - also needs to be told about controller resets, so it can suppress using and then re-initialize the debug port accordingly. Other than the in-tree driver, the hypervisor driver actually cares about doing this only for the device where the debug is port actually in use, i.e. it needs to be told the coordinates of the device being reset (quite obviously, leveraging the addition done for that would likely benefit the in-tree driver too).
