Instead, they had proposed to\nimplement it with an additional path through vm_normal_page(), using a bit in\nthe pte to determine whether or not the page should be refcounted:\n\nvm_normal_page()\n{\n\t...\n if (unlikely(vma-\u003evm_flags \u0026 (VM_PFNMAP|VM_MIXEDMAP))) {\n if (vma-\u003evm_flags \u0026 VM_MIXEDMAP) {\n#ifdef s390\n\t\t\tif (!mixedmap_refcount_pte(pte))\n\t\t\t\treturn NULL;\n#else\n if (!pfn_valid(pfn))\n return NULL;\n#endif\n goto out;\n }\n\t...\n}\n\nThis is fine, however if we are allowed to use a bit in the pte to determine\nrefcountedness, we can use that to _completely_ replace all the vma based\nschemes. So instead of adding more cases to the already complex vma-based\nscheme, we can have a clearly seperate and simple pte-based scheme (and get\nslightly better code generation in the process):\n\nvm_normal_page()\n{\n#ifdef s390\n\tif (!mixedmap_refcount_pte(pte))\n\t\treturn NULL;\n\treturn pte_page(pte);\n#else\n\t...\n#endif\n}\n\nAnd finally, we may rather make this concept usable by any architecture rather\nthan making it s390 only, so implement a new type of pte state for this.\nUnfortunately the old vma based code must stay, because some architectures may\nnot be able to spare pte bits. This makes vm_normal_page a little bit more\nugly than we would like, but the 2 cases are clearly seperate.\n\nSo introduce a pte_special pte state, and use it in mm/memory.c. It is\ncurrently a noop for all architectures, so this doesn\u0027t actually result in any\ncompiled code changes to mm/memory.o.\n\nBTW:\nI haven\u0027t put vm_normal_page() into arch code as-per an earlier suggestion.\nThe reason is that, regardless of where vm_normal_page is actually\nimplemented, the *abstraction* is still exactly the same. Also, while it\ndepends on whether the architecture has pte_special or not, that is the\nonly two possible cases, and it really isn\u0027t an arch specific function --\nthe role of the arch code should be to provide primitive functions and\naccessors with which to build the core code; pte_special does that. We do\nnot want architectures to know or care about vm_normal_page itself, and\nwe definitely don\u0027t want them being able to invent something new there\nout of sight of mm/ code. If we made vm_normal_page an arch function, then\nwe have to make vm_insert_mixed (next patch) an arch function too. So I\ndon\u0027t think moving it to arch code fundamentally improves any abstractions,\nwhile it does practically make the code more difficult to follow, for both\nmm and arch developers, and easier to misuse.\n\n[akpm@linux-foundation.org: build fix]\nSigned-off-by: Nick Piggin \u003cnpiggin@suse.de\u003e\nAcked-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nCc: Jared Hulbert

When we support\nIO memory, gfn_to_page() will fail for IO pages although gfn_to_pfn() will\nsucceed.\n\nThis does not implement support for avoiding reference counting for reserved\nRAM or for IO memory. However, it should make those things pretty straight\nforward.\n\nSince we\u0027re only introducing new common symbols, I don\u0027t think it will break\nthe non-x86 architectures but I haven\u0027t tested those. I\u0027ve tested Intel,\nAMD, NPT, and hugetlbfs with Windows and Linux guests.\n\n[avi: fix overflow when shifting left pfns by adding casts]\n\nSigned-off-by: Anthony Liguori \u003caliguori@us.ibm.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "9c20456a32ce9e82ccda55e12c10016b181d85e5", "tree": "06f8985c803d9ba90ffcc617a6403868c5f6f3c6", "parents": [ "3d45830c2b11a9d756faae161742b7d1ec417f7e" ], "author": { "name": "Joerg Roedel", "email": "joerg.roedel@amd.com", "time": "Tue Apr 01 16:44:56 2008 +0200" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Sun Apr 27 12:00:55 2008 +0300" }, "message": "KVM: function declaration parameter name cleanup\n\nThe kvm_host.h file for x86 declares the functions kvm_set_cr[0348].
