v10: - Responded to comments from Jan. v9: - Change to patch #1 only. v8: - Re-ordered series and dropped two patches that have already been committed. v7: - Fixed assertion failure hit during domain destroy. v6: - Responded to missed comments from Roger. v5: - Responded to review comments from Wei. v4: - Responded to further review comments from Roger. v3: - Dropped original patch #1 since it is covered by Juergen's patch. - Added new xenforeignmemorycleanup patch (#4). - Replaced the patch introducing the ioreq server 'is_default' flag with one that changes the ioreq server list into an array (#8). Paul Durrant (11): x86/hvm/ioreq: maintain an array of ioreq servers rather than a list 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/mm: add HYPERVISOR_memory_op to acquire guest resources x86/hvm/ioreq: add a new mappable resource type... x86/mm: add an extra command to HYPERVISOR_mmu_update... tools/libxenforeignmemory: add support for resource mapping tools/libxenforeignmemory: reduce xenforeignmemory_restrict code footprint common: add a new mappable resource type: XENMEM_resource_grant_table tools/libxenctrl: use new xenforeignmemory API to seed grant table tools/include/xen-sys/Linux/privcmd.h | 11 + tools/libs/devicemodel/core.c | 8 + tools/libs/devicemodel/include/xendevicemodel.h | 6 +- tools/libs/foreignmemory/Makefile | 2 +- tools/libs/foreignmemory/core.c | 53 ++ tools/libs/foreignmemory/freebsd.c | 7 - .../libs/foreignmemory/include/xenforeignmemory.h | 41 + tools/libs/foreignmemory/libxenforeignmemory.map | 5 + tools/libs/foreignmemory/linux.c | 45 ++ tools/libs/foreignmemory/minios.c | 7 - tools/libs/foreignmemory/netbsd.c | 7 - tools/libs/foreignmemory/private.h | 43 +- tools/libs/foreignmemory/solaris.c | 7 - tools/libxc/include/xc_dom.h | 8 +- tools/libxc/xc_dom_boot.c | 114 ++- 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/x86/hvm/dm.c | 9 +- xen/arch/x86/hvm/ioreq.c | 829 ++++++++++++--------- xen/arch/x86/mm.c | 39 +- xen/arch/x86/mm/p2m.c | 3 +- xen/common/compat/memory.c | 65 ++ xen/common/grant_table.c | 63 +- xen/common/memory.c | 132 ++++ xen/include/asm-x86/hvm/domain.h | 14 +- xen/include/asm-x86/hvm/ioreq.h | 2 + xen/include/asm-x86/mm.h | 5 + xen/include/asm-x86/p2m.h | 3 + xen/include/public/hvm/dm_op.h | 36 +- xen/include/public/memory.h | 47 +- xen/include/public/xen.h | 12 +- xen/include/xen/grant_table.h | 4 + xen/include/xlat.lst | 1 + 35 files changed, 1153 insertions(+), 494 deletions(-) --- Cc: Andrew Cooper <andrew.coop...@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: 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> -- 2.11.0 _______________________________________________ Xen-devel mailing list Xen-devel@lists.xen.org https://lists.xen.org/xen-devel
