This series introduces support for direct mapping of guest resources. The resources are: - Grant tables - IOREQ server pages
Paul Durrant (12): [x86|arm]: remove code duplication x86/mm: allow a privileged PV domain to map guest mfns x86/mm: add HYPERVISOR_memory_op to acquire guest resources tools/libxenforeignmemory: add support for resource mapping tools/libxenctrl: use new xenforeignmemory API to seed grant table x86/hvm/ioreq: rename .*pfn and .*gmfn to .*gfn x86/hvm/ioreq: use bool rather than bool_t x86/hvm/ioreq: move is_default into struct hvm_ioreq_server x86/hvm/ioreq: simplify code and use consistent naming x86/hvm/ioreq: use gfn_t in struct hvm_ioreq_page x86/hvm/ioreq: defer mapping gfns until they are actually requsted x86/hvm/ioreq: add a new mappable resource type... tools/include/xen-sys/Linux/privcmd.h | 11 + tools/libs/devicemodel/core.c | 18 +- tools/libs/devicemodel/include/xendevicemodel.h | 14 +- tools/libs/foreignmemory/Makefile | 2 +- tools/libs/foreignmemory/core.c | 42 ++ .../libs/foreignmemory/include/xenforeignmemory.h | 39 ++ tools/libs/foreignmemory/libxenforeignmemory.map | 5 + tools/libs/foreignmemory/linux.c | 45 ++ tools/libs/foreignmemory/private.h | 30 ++ tools/libxc/include/xc_dom.h | 8 +- tools/libxc/xc_dom_boot.c | 102 ++++- tools/libxc/xc_sr_restore_x86_hvm.c | 10 +- tools/libxc/xc_sr_restore_x86_pv.c | 2 +- tools/libxl/libxl_dom.c | 1 - tools/python/xen/lowlevel/xc/xc.c | 6 +- xen/arch/arm/mm.c | 29 +- xen/arch/x86/hvm/dm.c | 11 +- xen/arch/x86/hvm/hvm.c | 8 +- xen/arch/x86/hvm/io.c | 4 +- xen/arch/x86/hvm/ioreq.c | 453 ++++++++++++--------- xen/arch/x86/mm.c | 177 ++++++-- xen/arch/x86/mm/p2m.c | 3 +- xen/common/grant_table.c | 33 ++ xen/include/asm-x86/hvm/domain.h | 11 +- xen/include/asm-x86/hvm/ioreq.h | 20 +- xen/include/asm-x86/p2m.h | 3 + xen/include/public/hvm/dm_op.h | 46 ++- xen/include/public/memory.h | 41 +- xen/include/xen/grant_table.h | 3 + 29 files changed, 846 insertions(+), 331 deletions(-) --- Cc: Andrew Cooper <andrew.coop...@citrix.com> Cc: George Dunlap <george.dun...@eu.citrix.com> Cc: George Dunlap <george.dun...@eu.citrix.com> Cc: Ian Jackson <ian.jack...@eu.citrix.com> Cc: Jan Beulich <jbeul...@suse.com> Cc: Julien Grall <julien.gr...@arm.com> Cc: Konrad Rzeszutek Wilk <konrad.w...@oracle.com> Cc: Stefano Stabellini <sstabell...@kernel.org> Cc: Tim Deegan <t...@xen.org> Cc: Wei Liu <wei.l...@citrix.com> v2: - Support for IOREQ server pages added -- 2.11.0 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
