Hi all, Arm never supported a M2P yet there are some helpers implemented to deal with the common code. However, the implementation of mfn_to_gmfn is completely bogus. This series aims to properly disable the M2P on Arm. See patch #8 for the rationale regarding the lack of M2P on Arm. While looking at the code, I also continued to convert some code to use typesafe MFN/GFN. Cheers, Julien Grall (14): xen/arm: Use mfn_to_pdx instead of pfn_to_pdx when possible xen/x86: Constify the parameter "d" in mfn_to_gfn xen/x86: Make mfn_to_gfn typesafe xen/x86: Use mfn_to_gfn rather than mfn_to_gmfn xen/grant-table: Make arch specific macros typesafe xen: Convert hotplug page function to use typesafe MFN xen: Convert is_xen_fixed_mfn to use typesafe MFN xen: Convert is_xen_heap_mfn to use typesafe MFN xen: Introduce HAS_M2P config and use to protect mfn_to_gmfn call xen: Remove mfn_to_gmfn macro xen/x86: mm: Re-implement set_gpfn_from_mfn() as a static inline function xen/x86: pv: Convert update_intpte() to use typesafe MFN xen/mm: Convert {s, g}et_gpfn_from_mfn() to use typesafe MFN xen/mm: Provide dummy M2P-related helpers when !CONFIG_HAVE_M2P xen/arch/arm/mm.c | 2 +- xen/arch/x86/Kconfig | 1 + xen/arch/x86/cpu/mcheck/mcaction.c | 20 ++++--- xen/arch/x86/domain.c | 34 ++++++----- xen/arch/x86/mm.c | 115 ++++++++++++++++++------------------ xen/arch/x86/mm/mem_sharing.c | 19 +++--- xen/arch/x86/mm/p2m-pod.c | 4 +- xen/arch/x86/mm/p2m-pt.c | 37 ++++++------ xen/arch/x86/mm/p2m.c | 70 +++++++++++----------- xen/arch/x86/mm/paging.c | 4 +- xen/arch/x86/mm/shadow/common.c | 31 ++++++---- xen/arch/x86/mm/shadow/multi.c | 6 +- xen/arch/x86/pv/dom0_build.c | 6 +- xen/arch/x86/pv/emul-priv-op.c | 4 +- xen/arch/x86/pv/grant_table.c | 6 +- xen/arch/x86/pv/mm.h | 6 +- xen/arch/x86/pv/ro-page-fault.c | 2 +- xen/arch/x86/tboot.c | 2 +- xen/arch/x86/x86_64/traps.c | 41 ++++++------- xen/common/Kconfig | 3 + xen/common/domctl.c | 2 +- xen/common/grant_table.c | 4 +- xen/common/memory.c | 6 +- xen/common/page_alloc.c | 28 ++++----- xen/common/sysctl.c | 14 ++--- xen/drivers/passthrough/iommu.c | 13 ++-- xen/drivers/passthrough/x86/iommu.c | 16 ++--- xen/include/asm-arm/domain.h | 5 ++ xen/include/asm-arm/grant_table.h | 12 ++-- xen/include/asm-arm/mm.h | 31 +++------- xen/include/asm-x86/grant_table.h | 19 +++--- xen/include/asm-x86/mm.h | 46 +++++++-------- xen/include/asm-x86/p2m.h | 6 +- xen/include/public/domctl.h | 4 ++ xen/include/xen/domain.h | 8 +++ xen/include/xen/mm.h | 20 ++++++- 36 files changed, 344 insertions(+), 303 deletions(-) -- 2.11.0 _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxxxxxxxxx https://lists.xenproject.org/mailman/listinfo/xen-devel
