* libxc: convert gnttab interfaces to use an opaque handle typeIan Campbell2010-12-235-58/+65
| | | | | | | | | | | | | The xc_interface previously passed to xc_gnttab_* was only used for logging which can now be done via the xc_gnttab handle instead. This makes the interface consistent with the changes made to the main interface in 21483:779c0ef9682c. Also update QEMU_TAG to pull in the corresponding qemu change.

| | | | | | | | | | | | This makes the interface consistent with the changes made to the main interface in 21483:779c0ef9682c.

The NetBSD evtchn.h contains comments "Return allocated port" for several ioctls which currently return the allocated port as a member of the argument structure and not as the ioctl return value (I think this is a cut and paste error).

* x86 hvm: x2APIC emulationKeir Fraser2010-12-072-1/+3
| | | | | | | | | | | This patch would enable Xen to handle x2APIC MSR accessing of HVM guest, which is faster(avoid decoding of MMIO accessing).

* minios: reverse layering of xc vs minios fd closeKeir Fraser2010-12-031-8/+24
| | | | | | | | | | | | Having minios close() call back into the libxc core close routines is backwards and unexpected. On every other OS the libxc core close routine calls close(). Export minios specific functions from the minios libxc code to implement fd closing for each type of xc file handle and simply call close() in the core close routine.

* tools: change cpumaps to uint8_tJuergen Gross2010-11-034-44/+87
| | | | | | | | | | | | | | | | | | | | Cpumap types in tools (libxc and libxl) are changed to be based on bytes like in the interface to the hypervisor. To make handling easier the size of used cpumaps is always based on the number of physical cpus supported by the hypervisor. This eliminates the need to keep track of the cpumap size in external interfaces. In libxl a macro for cycling through a cpumap is added (libxl_for_each_cpu). Interfaces changed: libxl_set_vcpuaffinity() libxl_cpumap_alloc() xc_vcpu_setaffinity() xc_vcpu_getaffinity() xc_cpupool_freeinfo() Signed-off-by: Juergen Gross <juergen.gross@ts.fujitsu.com> Acked-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* Fix ia64 tools buildKeir Fraser2010-11-021-0/+46
| | | | | | | | | | | 22066:eccfdeb41b80 replaced tools/libxc/ia64/aclinux.h with xen/include/acpi/platform/aclinux.h. Because both are incompatible, tools cannot be built on ia64.

* libxl: Fix migration of HVM guestsIan Campbell2010-10-282-5/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | In the default "QemuDeviceModelRecord"-style HVM tail of the migration protocol the size of the qemu save record is unknown at the receiver and therefore it must read until EOF. This is not compatible with the xl migration protocol which contains a post-migration handshake and therefore cannot close the socket on the sending end. What is required is an explicit length field for the save record, which the "RemusDeviceModelState"-style HVM tail includes. Rather than overload the "RemusDeviceModelState" name for a non-Remus use case (on off chance that they need to diverge for some reason in the future) introduce a third style called "DeviceModelRecord0002" which is identical to current "RemusDeviceModelState"-style. Hopefully the inclusion of a number here will allow easier extension in the future without needing to come up with increasingly less helpful names! Also propagate errors from xc_domain_save and libxl__domain_suspend_common to callers. Signed-off-by: Ian Campbell <ian.campbell@citrix.com> Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* libxc: do not align/lock buffers which do not need itIan Campbell2010-10-222-24/+3
| | | | | | | | | | | | | | | | | | | | | On restore: region_mfn is passed to xc_map_foreign_range and xc_map_foreign_bulk. In both cases the buffer is accessed from the ioctl handler in the kernel and not from any hypercall. Therefore normal copy_{to,from}_user handling in the kernel will cope with any faulting access. p2m_batch is passed to xc_domain_memory_populate_physmap which takes care of bouncing the buffer already. On save: pfn_type is passed to xc_map_foreign_bulk which does not need locking as per region_mfn above.
