This patch\nfeatures the following diagnose codes:\n- vm storage size, that tells the guest about its memory layout\n- time slice end, which is used by the guest to indicate that it waits\n for a lock and thus cannot use up its time slice in a useful way\n- ipl functions, which a guest can use to reset and reboot itself\n\nIn order to implement ipl functions, we also introduce an exit reason that\ncauses userspace to perform various resets on the virtual machine. All resets\nare described in the principles of operation book, except KVM_S390_RESET_IPL\nwhich causes a reboot of the machine.\n\nAcked-by: Martin Schwidefsky \u003cmartin.schwidefsky@de.ibm.com\u003e\nSigned-off-by: Christian Borntraeger \u003cborntraeger@de.ibm.com\u003e\nSigned-off-by: Carsten Otte \u003ccotte@de.ibm.com\u003e\nSigned-off-by: Avi Kivity \u003cavi@qumranet.com\u003e\n" }, { "commit": "ba5c1e9b6ceebdc39343cc03eb39f077abd3c571", "tree": "ab07e763ad7d9aad2ef189def5537e73a50c7503", "parents": [ "8f2abe6a1e525e878bdf58f68ccd146d543fde84" ], "author": { "name": "Carsten Otte", "email": "cotte@de.ibm.com", "time": "Tue Mar 25 18:47:26 2008 +0100" }, "committer": { "name": "Avi Kivity", "email": "avi@qumranet.com", "time": "Sun Apr 27 12:00:44 2008 +0300" }, "message": "KVM: s390: interrupt subsystem, cpu timer, waitpsw\n\nThis patch contains the s390 interrupt subsystem (similar to in kernel apic)\nincluding timer interrupts (similar to in-kernel-pit) and enabled wait\n(similar to in kernel hlt).\n\nIn order to achieve that, this patch also introduces intercept handling\nfor instruction intercepts, and it implements load control instructions.\n\nThis patch introduces an ioctl KVM_S390_INTERRUPT which is valid for both\nthe vm file descriptors and the vcpu file descriptors. In case this ioctl is\nissued against a vm file descriptor, the interrupt is considered floating.\nFloating interrupts may be delivered to any virtual cpu in the configuration.\n\nThe following interrupts are supported:\nSIGP STOP - interprocessor signal that stops a remote cpu\nSIGP SET PREFIX - interprocessor signal that sets the prefix register of a\n (stopped) remote cpu\nINT EMERGENCY - interprocessor interrupt, usually used to signal need_reshed\n and for smp_call_function() in the guest.\nPROGRAM INT - exception during program execution such as page fault, illegal\n instruction and friends\nRESTART - interprocessor signal that starts a stopped cpu\nINT VIRTIO - floating interrupt for virtio signalisation\nINT SERVICE - floating interrupt for signalisations from the system\n service processor\n\nstruct kvm_s390_interrupt, which is submitted as ioctl parameter when injecting\nan interrupt, also carrys parameter data for interrupts along with the interrupt\ntype.

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" } ] }
