xen: synchronize include/xen/interface/xen.h with xen

2015-03-16T14:49:13Z

The header include/xen/interface/xen.h doesn't contain all definitions from Xen's version of that header. Update it accordingly. Signed-off-by: Juergen Gross Reviewed-by: David Vrabel Signed-off-by: David Vrabel

xen: sync some headers with xen tree

2014-10-03T11:34:52Z

To be able to use an initially unmapped initrd with xen the following header files must be synced to a newer version from the xen tree: include/xen/interface/elfnote.h include/xen/interface/xen.h As the KEXEC and DUMPCORE related ELFNOTES are not relevant for the kernel they are omitted from elfnote.h.

arm: xen: implement multicall hypercall support.

2014-04-24T12:09:46Z

As part of this make the usual change to xen_ulong_t in place of unsigned long. This change has no impact on x86. The Linux definition of struct multicall_entry.result differs from the Xen definition, I think for good reasons, and used a long rather than an unsigned long. Therefore introduce a xen_long_t, which is a long on x86 architectures and a signed 64-bit integer on ARM. Use uint32_t nr_calls on x86 for consistency with the ARM definition. Build tested on amd64 and i386 builds. Runtime tested on ARM. Signed-off-by: Ian Campbell Cc: Stefano Stabellini Cc: Konrad Rzeszutek Wilk Cc: Boris Ostrovsky Signed-off-by: David Vrabel

xen/events: Add the hypervisor interface for the FIFO-based event channels

2014-01-06T15:07:52Z

Add the hypercall sub-ops and the structures for the shared data used in the FIFO-based event channel ABI. The design document for this new ABI is available here: http://xenbits.xen.org/people/dvrabel/event-channels-H.pdf In summary, events are reported using a per-domain shared event array of event words. Each event word has PENDING, LINKED and MASKED bits and a LINK field for pointing to the next event in the event queue. There are 16 event queues (with different priorities) per-VCPU. Key advantages of this new ABI include: - Support for over 100,000 events (2^17). - 16 different event priorities. - Improved fairness in event latency through the use of FIFOs. The ABI is available in Xen 4.4 and later. Signed-off-by: David Vrabel Reviewed-by: Konrad Rzeszutek Wilk Reviewed-by: Boris Ostrovsky

xen: event channel arrays are xen_ulong_t and not unsigned long

2013-02-20T13:45:07Z

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/vga: add the xen EFI video mode support

2012-09-24T13:28:57Z

In order to add xen EFI frambebuffer video support, it is required to add xen-efi's new video type (XEN_VGATYPE_EFI_LFB) case and handle it in the function xen_init_vga and set the video type to VIDEO_TYPE_EFI to enable efi video mode.

xen: Introduce xen_pfn_t for pfn and mfn types

2012-08-23T14:18:17Z

All the original Xen headers have xen_pfn_t as mfn and pfn type, however when they have been imported in Linux, xen_pfn_t has been replaced with unsigned long. That might work for x86 and ia64 but it does not for arm. Bring back xen_pfn_t and let each architecture define xen_pfn_t as they see fit.

xen/pcpu: Xen physical cpus online/offline sys interface

2012-07-19T19:51:39Z

This patch provide Xen physical cpus online/offline sys interface. User can use it for their own purpose, like power saving: by offlining some cpus when light workload it save power greatly. Its basic workflow is, user online/offline cpu via sys interface, then hypercall xen to implement, after done xen inject virq back to dom0, and then dom0 sync cpu status.
