2014-08-28xen: hvm: Abstract away memory region name refPeter Crosthwaite
The mr->name field is removed. This slipped through compile testing. Fix. Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-08-28xen-hvm: Constify stringPeter Crosthwaite
It's constant, and sourced from existing const strings. Avoid dodgy casts by converting to const. Signed-off-by: Peter Crosthwaite <peter.crosthwaite@xilinx.com> Reviewed-by: Stefan Weil <sw@weilnetz.de> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2014-08-01xen: fix usage of ENODATARoger Pau Monne
ENODATA doesn't exist on FreeBSD, so ENODATA errors returned by the hypervisor are translated to ENOENT. Also, the error code is returned in errno if the call returns -1, so compare the error code with the value in errno instead of the value returned by the function.

2014-07-07xen: build on ARMStefano Stabellini
Collection of fixes to build QEMU with Xen support on ARM: - use xenstore_read_fe_uint64 to retrieve the page-ref (xenfb); - use xen_pfn_t instead of unsigned long in xenfb; - unsigned long/xenpfn_t in xen_remove_from_physmap; - in xen-mapcache.c use HOST_LONG_BITS to check for QEMU's address space size.

2014-06-11xen: replace ffsl with ctzlNatanael Copa
ffsl is a GNU extension and not available in musl libc. See also commit fbeadf50 (bitops: unify bitops_ffsl with the one in host-utils.h, call it bitops_ctzl) on why ctzl should be used instead of ffsl.

2014-05-07xen: factor out common functionsWei Liu
So common functions used by both HVM and PV are factored out from xen-all.c to xen-common.c. Finally rename xen-all.c to xen-hvm.c, as those functions are only useful to HVM guest. Create *-stub files and modify Makefile.target to reflect the changes. Signed-off-by: Wei Liu <wei.liu2@citrix.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
