* libxc: wrappers for XENMEM {increase,decrease}_reservation and populate_physmapIan Campbell2010-10-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently the wrappers for these hypercalls swallow partial success and return failure to the caller. In order to use these functions more widely instead of open-coding uses of XENMEM_* and xc_memory_op add variants which return the actual hypercall result. Therefore add the following functions: xc_domain_increase_reservation xc_domain_decrease_reservation xc_domain_populate_physmap and implement the existing semantics using these new functions as xc_domain_increase_reservation_exact xc_domain_decrease_reservation_exact xc_domain_populate_physmap_exact replacing the existing xc_domain_memory_* functions. Use these new functions to replace all open coded uses of XENMEM_increase_reservation, XENMEM_decrease_reservation and XENMEM_populate_physmap. Also rename xc_domain_memory_*_pod_target to xc_domain_*_pod_target for consistency. Temporarily add a compatibility macro for xc_domain_memory_populate_physmap to allow time for qemu to catch up.

Copyright holders have been contacted by Stephen Spector and have all agreed this change. Removed tools/libxc/ia64/aclinux.h since it appeared to be unused. There is a separate, more up to date, copy in xen/include/acpi/platform/aclinux.h which does appear to be used. Clarify the license of MiniOS privcmd.h under the same terms as other tools/include/xen-sys headers.

* libxc: eliminate static variables, use xentoollog; API changeKeir Fraser2010-05-281-63/+62
| | | | | | | | | | | | | | | | | | | | This patch eliminate the global variables in libxenctrl (used for logging and error reporting). Instead the information which was in the global variables is now in a new xc_interface* opaque structure, which xc_interface open returns instead of the raw file descriptor; furthermore, logging is done via xentoollog. There are three new parameters to xc_interface_open to control the logging, but existing callers can just pass "0" for all three to get the old behaviour. All libxc callers have been adjusted accordingly. Also update QEMU_TAG for corresponding qemu change. Signed-off-by: Ian Jackson <ian.jackson@eu.citrix.com>

* x86_64: allow more vCPU-s per guestKeir Fraser2009-06-181-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Add support for superpages (hugepages) in PV domainKeir Fraser2009-05-261-11/+44
| | | | | | | | | | | | | | | | | | This patch adds the option "superpages" to the domain configuration file. If it is set, the domain is populated using 2M pages. This code does not support fallback to small pages. If the domain can not be created with 2M pages, the create will fail. The patch also includes support for saving and restoring domains with the superpage flag set. However, if a domain has freed small pages within its physical page array and then extended the array, the restore will fill in those freed pages. It will then attempt to allocate more than its memory limit and will fail. This is significant because apparently Linux does this during boot, thus a freshly booted Linux image can not be saved and restored successfully. Signed-off-by: Dave McCracken <dcm@mccr.org>
