* Fix the compatibility typedef of ioservid_t to match the Xen headersPaul Durrant2015-07-081-1/+1
| | | | | | | | | | | | There is a mismatch between the definition of ioservid_t in xen_common.h and the definition in the Xen public headers. This patch corrects the definition in xen_common.h.

* fix QEMU build on Xen/ARMStefano Stabellini2015-01-261-4/+9
| | | | | | | | | | | xen_get_vmport_regs_pfn should take a xen_pfn_t argument, not an unsigned long argument (in fact xen_pfn_t is defined as uint64_t on ARM). Also use xc_hvm_param_get instead of the deprecated xc_get_hvm_param. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com> Reviewed-by: Don Slutz <dslutz@verizon.com>
* Xen: Use the ioreq-server API when availablePaul Durrant2015-01-201-0/+223
| | | | | | | | | | | | | | | | The ioreq-server API added to Xen 4.5 offers better security than the existing Xen/QEMU interface because the shared pages that are used to pass emulation request/results back and forth are removed from the guest's memory space before any requests are serviced. This prevents the guest from mapping these pages (they are in a well known location) and attempting to attack QEMU by synthesizing its own request structures. Hence, this patch modifies configure to detect whether the API is available, and adds the necessary code to use the API if it is.

* xen-hvm.c: Add support for Xen access to vmportDon Slutz2014-10-301-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | This adds synchronisation of the 6 vcpu registers (only 32bits of them) that vmport.c needs between Xen and QEMU. This is to avoid a 2nd and 3rd exchange between QEMU and Xen to fetch and put these 6 vcpu registers used by the code in vmport.c and vmmouse.c The registers are passed in the new shared page provided by HVM_PARAM_VMPORT_REGS_PFN. Add new array to XenIOState that allows selection of current_cpu by vcpu id. Now pass XenIOState to handle_ioreq(). Add new routines regs_to_cpu(), regs_from_cpu(), and handle_vmport_ioreq().

* xen_disk: add discard supportOlaf Hering2014-05-071-0/+7
| | | | | | | | | | | | | Implement discard support for xen_disk. It makes use of the existing discard code in qemu. The discard support is enabled unconditionally. The tool stack may provide a property "discard-enable" in the backend node to optionally disable discard support. This is helpful in case the backing file was intentionally created non-sparse to avoid fragmentation.

* hw: move headers to include/Paolo Bonzini2013-04-081-0/+160
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
