* Fix emacs local variable block to use correct C style variable.David Vrabel2013-02-211-1/+1
| | | | | | | The emacs variable to set the C style from a local variable block is c-file-style, not c-set-style. Signed-off-by: David Vrabel <david.vrabel@citrix.com
* HVM firmware passthrough control tools supportRoss Philipson2013-01-101-1/+1
| | | | | | | | | | | | Xen control tools support for loading the firmware passthrough blocks during domain construction. SMBIOS and ACPI blocks are passed in using the new xc_hvm_build_args structure. Each block is read and loaded into the new domain address space behind the HVMLOADER image. The base address for the two blocks is returned as an out parameter to the caller via the args structure.

* libxc: pass arguments to xc_hvm_build() in a structureDavid Vrabel2012-03-011-2/+1
| | | | | | | | | | | | | | | To allow new parameters to be added to the xc_hvm_build*() family of functions, pass them in a structure. Make the other variants fill in the structure and call xc_hvm_build() (except for xc_hvm_build_mem() which had no users and is removed). The units of the mem_size and mem_target arguments are in bytes (not MiB like the old functions).

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 Fraser2010-05-281-5/+7
| | | | | | | | | | | | | | | | | | | | 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>
* libxc: New hcall_buf_{prep,release} pre-mlock interfaceKeir Fraser2010-01-221-16/+0
| | | | | | | | | | Allow certain performance-critical hypercall wrappers to register data buffers via a new interface which allows them to be 'bounced' into a pre-mlock'ed page-sized per-thread data area. This saves the cost of mlock/munlock on every such hypercall, which can be very expensive on modern kernels. Signed-off-by: Keir Fraser <keir.fraser@citrix.com>
