* tools: foreign: add checks for compatible architecturesIan Campbell2013-08-202-2/+24

* xen: arm: include public/xen.h in foreign interface checkingIan Campbell2013-08-204-12/+18
| | | | | | | | | | | | | | | | | mkheader.py doesn't cope with struct foo { }; so add a newline. Define unsigned long and long to a non-existent type on ARM so as to catch their use. Teach mkheader.py to cope with structs which are ifdef'd. This cannot cope with #defines between the #ifdef and the struct definitions, so move MAX_GUEST_CMDLINE to be next to its only usage.

* tools: foreign: ensure 64 bit values are properly aligned for armIan Campbell2013-02-261-4/+10
| | | | | | | | When building the foreign headers on x86_32 we use '#pragma pack(4)' and therefore need to explicitly align types which should be aligned to 8-byte boundaries. Signed-off-by: Ian Campbell <ian.campbell@citrix.com>
* xen: arm: separate guest user regs from internal guest state.Ian Campbell2013-02-223-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | struct cpu_user_regs is currently used as both internal state (specifically at the base of the stack) and a guest/toolstack visible API (via struct vcpu_guest_context used by XEN_DOMCTL_{g,s}etvcpucontext and VCPUOP_initialise). This causes problems when we want to make the API 64-bit clean since we don't really want to change the size of the on-stack struct. So split into vcpu_guest_core_regs which is the API facing struct and keep cpu_user_regs purely internal, translate between the two. In the user API arrange for both 64- and 32-bit registers to be included in a layout which does not differ depending on toolstack architecture. Also switch to using the more formal banked register names (e.g. with the _usr suffix) for clarity. This is an ABI change. Note that the kernel doesn't currently use this data structure so it affects the tools interface only. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Acked-by: Tim Deegan <tim@xen.org>

* tools: Synchronize privcmd header constantsAndres Lagar-Cavilla2012-11-121-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | Since Linux's git commit ceb90fa0a8008059ecbbf9114cb89dc71a730bb6, the privcmd.h interface between Linux and libxc specifies two new constants, PRIVCMD_MMAPBATCH_MFN_ERROR and PRIVCMD_MMAPBATCH_PAGED_ERROR. These constants represent the error codes encoded in the top nibble of an mfn slot passed to the legacy MMAPBATCH ioctl. In particular, libxenctrl checks for the equivalent of the latter constant when dealing with paged out frames that might be the target of a foreign map. Previously, the relevant constant was defined in the domctl hypervisor interface header (XEN_DOMCTL_PFINFO_PAGEDTAB). Because this top-nibble encoding is a contract between the dom0 kernel and libxc, a domctl.h definition is misplaced. - Sync the privcmd.h header to that now available in upstream Linux - Update libxc appropriately - Remove the unnecessary constant in domctl.h Signed-off-by: Andres Lagar-Cavilla <andres@lagarcavilla.org> Acked-by: Ian Campbell <ian.campbelL@citrix.com> Committed-by: Ian Campbell <ian.campbell@citrix.com>

* mini-os: use BSD sys/queue.h instead of Linux list.hIan Campbell2012-01-315-0/+1903
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latter is GPL which makes the whole of mini-os GPL rather than BSD as intended. In tree users are all GPL or GPL-compatible but we should fix this so that mini-os is BSD. Do so by using the same BSD sys/queue.h as we use in libxl. Tested with the builtin mini-os test app and qemu stubdomain, both of which appear to still function as expected. Move tools/libxl/external and the associated sed script to tools/include/xen-external to allow more sensible access from mini-os. Also add s/NULL/0/ in the sed script due to NULL not always being defined in stubdom code when mini-os/wait.h is included. As well as the obvious ABI changes there are a few API updates associated with the change: - struct rw_semaphore.wait_list is unused - remove_waiter needs to take the wait_queue_head The latter requires a qemu update, so there is also a QEMU_TAG update in this changeset. I sprinkled some extra-emacs local variables around the files I edited which didn't have them. I think this should be backported to the stable branches since external users of mini-os may have been mislead into thinking they could safely link mini-os against GPL-incompatible code.

* libxc: add xc_gnttab_map_grant_ref_notifyDaniel De Graaf2011-10-061-1/+32
| | | | | | | | | | | | | | | Normally, when a userspace process mapping a grant crashes, the domain providing the reference receives no indication that its peer has crashed, possibly leading to unexpected freezes or timeouts. This function provides a notification of the unmap by signalling an event channel and/or clearing a specific byte in the page. This also unifies the 3 very similar grant-mapping osdep interfaces into a single function instead of introducing yet another minor variation.

* libxc: use new (replacement) mmap-batch ioctlKeir Fraser2010-01-131-0/+10
| | | | | | | | | | | | | | | | | | | | Replace all calls to xc_map_foreign_batch() where the caller doesn't look at the passed in array to check for errors by calls to xc_map_foreign_pages(). Replace all remaining calls by such to the newly introduced xc_map_foreign_bulk(). As a sideband modification (needed while writing the patch to ensure they're unused) eliminate unused parameters to uncanonicalize_pagetable() and xc_map_foreign_batch_single(). Also unmap live_p2m_frame_list earlier in map_and_save_p2m_table(), reducing the peak amount of virtual address space required. All supported OSes other than Linux continue to use the old ioctl for the time being. Also change libxc's MAJOR to 4.0 to reflect the API change. Signed-off-by: Jan Beulich <jbeulich@novell.com>

* x86_64: allow more vCPU-s per guestKeir Fraser2009-06-181-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Since the shared info layout is fixed, guests are required to use VCPUOP_register_vcpu_info prior to booting any vCPU beyond the traditional limit of 32. MAX_VIRT_CPUS, being an implemetation detail of the hypervisor, is no longer being exposed in the public headers. The tools changes are clearly incomplete (and done only so things would build again), and the current state of the tools (using scalar variables all over the place to represent vCPU bitmaps) very likely doesn't permit booting DomU-s with more than the traditional number of vCPU-s. Testing of the extended functionality was done with Dom0 (96 vCPU-s, as well as 128 vCPU-s out of which the kernel elected - by way of a simple kernel side patch - to use only some, resulting in a sparse bitmap). ia64 changes only to make things build, and build-tested only (and the tools part only as far as the build would go without encountering unrelated problems in the blktap code).

* x86-64: guest directed placement of initial p->m mapKeir Fraser2009-01-081-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | By adding another ELF note, the kernel can now direct the hypervisor (for Dom0) and in the future also the tools (for DomU-s) to place the initial phys->mach translation table at other than an address immediately above the kernel/initrd images. This eliminates the size restriction imposed on this table by Linux (the kernel loads above the -2Gb boundary, and hence the entire initial mapping cannot reach or even exceed 2Gb). There are a few items in this patch I'm not particularly happy with, but couldn't think of a better solution: - there is a hidden assumption that pages allocated for the domain are put on the domain's page list sequentially - the way backward compatibility is maintained is placing requirements on the kernel side that make the code somewhat convoluted (because it needs to check where the map is actually placed in quite a few places) - code is there to use 1Gb mappings for the hypervisor created table, but lacking a machine with 512G+ memory for immediate testing I can't verify this works; I know that 2Mb mappings work, and hence imply that 1Gb ones would too (of course, if the kernel replaces the table - like Linux does -, it cannot use 2Mb/1Gb mappings or even try to re-use the page table entries, but I don't consider this a problem) Signed-off-by: Jan Beulich <jbeulich@novell.com>
