* Use a reserved pfn in the guest address space to store mem event ringsTim Deegan2012-03-0810-77/+184
| | | | | | | | | | | | | | | | | | This solves a long-standing issue in which the pages backing these rings were pages belonging to dom0 user-space processes. Thus, if the process would die unexpectedly, Xen would keep posting events to a page now belonging to some other process. We update all API-consumers in tree (xenpaging and xen-access). This is an API/ABI change, so please speak up if it breaks your accumptions. The patch touches tools, hypervisor x86/hvm bits, and hypervisor x86/mm bits.

* Tools: Remove shared page from mem_event/access/paging interfacesTim Deegan2012-03-087-46/+33
| | | | | | | | | | | | | | | | | | | | | | Don't use the superfluous shared page, return the event channel directly as part of the domctl struct, instead. In-tree consumers (xenpaging, xen-access) updated. This is an ABI/API change, so please voice any concerns. Known pending issues: - pager could die and its ring page could be used by some other process, yet Xen retains the mapping to it. - use a saner interface for the paging_load buffer. This change also affects the x86/mm bits in the hypervisor that process the mem_event setup domctl.

* xenpaging: remove obsolete XENMEM_paging_op_resumeOlaf Hering2012-03-013-20/+1
| | | | | | | | | | | | | | | | | | | | With changeset 24364:0964341efd65 an event channel based notification of new responses in the ringbuffer is implemented. This makes the memevent interface obsolete. Currently a call to p2m_mem_paging_resume() is triggered twice by xenpaging, once per memevent and once per even channel. In practice this double call does not lead to issues because p2m_mem_paging_resume() processes only available events. xenpaging used the event channel notification since the beginning, but it was a no-op until changeset mentioned above. This change removes the unneeded XENMEM_paging_op_resume functionality. Pagers are notified via an event channel of new requests, and now they are required to notify the hypervisor about their responses also with an event channel.

* libxc: add MMIO hole size parameter to xc_hvm_build()David Vrabel2012-03-012-11/+19
| | | | | | | | | | | | | | | | | Add a parameter for the MMIO hole size when building a HVM domain. This is useful for specifying a larger than normal MMIO hole to ensure that no PCIe device's MMIO region overlaps with RAM in a guest's physical address space. This is needed on certain systems with PCIe switches with a broken ACS capability. On these systems, if a device downstream of the switch attempts a DMA to a guest physical address that overlaps with the MMIO region of another downstream device, then the switch routes the transfer directly to the device and the read or write never hits RAM.
