This probably\n never happens under normal guests.\n - if injection fails due to a physical interrupt causing a vmexit so that\n it can be handled by the host.\n\nIn all cases the guest proceeds without processing the interrupt, reducing\nthe interactive feel and interrupt throughput of the guest.\n\nThis patch fixes the situation by allowing userspace to request an exit\nwhen the \u0027interrupt window\u0027 opens, so that it can re-inject the interrupt\nat the right time. Guest interactivity is very visibly improved.\n\nSigned-off-by: Dor Laor \u003cdor.laor@qumranet.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nAcked-by: Ingo Molnar \u003cmingo@elte.hu\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "3bab1f5dda3443043cc8fe68c5ae75530339f28f", "tree": "d1b675e8f5328094c1a3d651da5e7563ad692252", "parents": [ "671d6564796e0c90398aab30f89b5e48fc5a3fbe" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Fri Dec 29 16:49:48 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sat Dec 30 10:56:44 2006 -0800" }, "message": "[PATCH] KVM: Move common msr handling to arch independent code\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "671d6564796e0c90398aab30f89b5e48fc5a3fbe", "tree": "9e8b0712f44f8b86e48a876b9a6b8db3836e67c4", "parents": [ "09db28b8a3765a7ec35eba80420c71a7973f5a88" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Fri Dec 29 16:49:45 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sat Dec 30 10:56:44 2006 -0800" }, "message": "[PATCH] KVM: Implement a few system configuration msrs\n\nResolves sourceforge bug 1622229 (guest crashes running benchmark software).\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "a9058ecd3cd72634cf548588ce79b3f225c9ca32", "tree": "11d1edd2dfdcec03ba6b54b3b06d41cae826b940", "parents": [ "1e885461f02259d75e7480a70d291d2d8aaa938e" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Fri Dec 29 16:49:37 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sat Dec 30 10:56:44 2006 -0800" }, "message": "[PATCH] KVM: Simplify is_long_mode()\n\nInstead of doing tricky stuff with the arch dependent virtualization\nregisters, take a peek at the guest\u0027s efer.\n\nThis simlifies some code, and fixes some confusion in the mmu branch.\n\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" }, { "commit": "1e885461f02259d75e7480a70d291d2d8aaa938e", "tree": "775ae3f9cd24e5f428ffd7f225250f5c85450d00", "parents": [ "2b7a52a459cb09864b736265bee1af5cef42af66" ], "author": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Fri Dec 29 16:49:34 2006 -0800" }, "committer": { "name": "Linus Torvalds", "email": "torvalds@woody.osdl.org", "time": "Sat Dec 30 10:56:43 2006 -0800" }, "message": "[PATCH] KVM: Use boot_cpu_data instead of current_cpu_data\n\ncurrent_cpu_data invokes smp_processor_id(), which is inadvisable when\npreemption is enabled.

The driver adds a character device\n(/dev/kvm) that exposes the virtualization capabilities to userspace. Using\nthis driver, a process can run a virtual machine (a \"guest\") in a fully\nvirtualized PC containing its own virtual hard disks, network adapters, and\ndisplay.\n\nUsing this driver, one can start multiple virtual machines on a host.\n\nEach virtual machine is a process on the host; a virtual cpu is a thread in\nthat process. kill(1), nice(1), top(1) work as expected. In effect, the\ndriver adds a third execution mode to the existing two: we now have kernel\nmode, user mode, and guest mode. Guest mode has its own address space mapping\nguest physical memory (which is accessible to user mode by mmap()ing\n/dev/kvm). Guest mode has no access to any I/O devices; any such access is\nintercepted and directed to user mode for emulation.\n\nThe driver supports i386 and x86_64 hosts and guests. All combinations are\nallowed except x86_64 guest on i386 host. For i386 guests and hosts, both pae\nand non-pae paging modes are supported.\n\nSMP hosts and UP guests are supported. At the moment only Intel\nhardware is supported, but AMD virtualization support is being worked on.\n\nPerformance currently is non-stellar due to the naive implementation of the\nmmu virtualization, which throws away most of the shadow page table entries\nevery context switch. We plan to address this in two ways:\n\n- cache shadow page tables across tlb flushes\n- wait until AMD and Intel release processors with nested page tables\n\nCurrently a virtual desktop is responsive but consumes a lot of CPU. Under\nWindows I tried playing pinball and watching a few flash movies; with a recent\nCPU one can hardly feel the virtualization. Linux/X is slower, probably due\nto X being in a separate process.\n\nIn addition to the driver, you need a slightly modified qemu to provide I/O\ndevice emulation and the BIOS.\n\nCaveats (akpm: might no longer be true):\n\n- The Windows install currently bluescreens due to a problem with the\n virtual APIC. We are working on a fix. A temporary workaround is to\n use an existing image or install through qemu\n- Windows 64-bit does not work. That\u0027s also true for qemu, so it\u0027s\n probably a problem with the device model.\n\n[bero@arklinux.org: build fix]\n[simon.kagstrom@bth.se: build fix, other fixes]\n[uril@qumranet.com: KVM: Expose interrupt bitmap]\n[akpm@osdl.org: i386 build fix]\n[mingo@elte.hu: i386 fixes]\n[rdreier@cisco.com: add log levels to all printks]\n[randy.dunlap@oracle.com: Fix sparse NULL and C99 struct init warnings]\n[anthony@codemonkey.ws: KVM: AMD SVM: 32-bit host support]\nSigned-off-by: Yaniv Kamay \u003cyaniv@qumranet.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\nCc: Simon Kagstrom \u003csimon.kagstrom@bth.se\u003e\nCc: Bernhard Rosenkraenzer \u003cbero@arklinux.org\u003e\nSigned-off-by: Uri Lublin \u003curil@qumranet.com\u003e\nCc: Ingo Molnar \u003cmingo@elte.hu\u003e\nCc: Roland Dreier \u003crolandd@cisco.com\u003e\nSigned-off-by: Randy Dunlap \u003crandy.dunlap@oracle.com\u003e\nSigned-off-by: Anthony Liguori \u003canthony@codemonkey.ws\u003e\nSigned-off-by: Andrew Morton \u003cakpm@osdl.org\u003e\nSigned-off-by: Linus Torvalds \u003ctorvalds@osdl.org\u003e\n" } ] }
