guest vcpu.\n\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n" }, { "commit": "68e2ffed358c92341c126e606b500098fc72f5f7", "tree": "20f710a745f7ba4452fce413e83a6a8c67300ac3", "parents": [

On POWER7,\nthe FP registers are the upper halves of the VSX registers vsr0 - vsr31.\nPR KVM stores vsr0 - vsr31 in two halves, with the upper halves in the\narch.fpr[] array and the lower halves in the arch.vsr[] array, whereas\nHV KVM on POWER7 stores the whole VSX register in arch.vsr[].\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\n[agraf: fix whitespace, vsx compilation]\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n" }, { "commit": "a136a8bdc02fc14625ac45ee846cc646fc46597e", "tree": "7016d41b16ea11769f918526eca63a80b3014d71", "parents": [ "5bd1cf118533aba41b3fbd4834e6362a9237db71" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Tue Sep 25 20:31:56 2012 +0000" }, "committer": { "name": "Alexander Graf", "email": "agraf@suse.de", "time": "Fri Oct 05 23:38:54 2012 +0200" }, "message": "KVM: PPC: Book3S: Get/set guest SPRs using the GET/SET_ONE_REG interface\n\nThis enables userspace to get and set various SPRs (special-purpose\nregisters) using the KVM_[GS]ET_ONE_REG ioctls.

When we later realize that\nit\u0027s a better idea to shove over multiple registers at once, we can reuse\nmost of the infrastructure and simply implement a GET_MANY_REGS / SET_MANY_REGS\ninterface.\n\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n\n" }, { "commit": "dc83b8bc0256ee682506ed83853a98eaba529c6f", "tree": "0d5f73b725392104320894d606bba10151a9ea3c", "parents": [ "0164c0f0c404017fb04defb0ceb23fd1c3c3a53e" ], "author": { "name": "Scott Wood", "email": "scottwood@freescale.com", "time": "Thu Aug 18 15:25:21 2011 -0500" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Mon Mar 05 14:52:24 2012 +0200" }, "message": "KVM: PPC: e500: MMU API\n\nThis implements a shared-memory API for giving host userspace access to\nthe guest\u0027s TLB.\n\nSigned-off-by: Scott Wood \u003cscottwood@freescale.com\u003e\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\nSigned-off-by: Avi Kivity \u003cavi@redhat.com\u003e\n\n" }, { "commit": "b9e5dc8d4511e6a00862a795319569e7fe7f60f4", "tree": "1be01a8d13e2e5023c22db4a7dd87518f14af5b3", "parents": [ "8d26cf7b40b1648c39e77a113dac07ad31363120" ], "author": { "name": "Christian Borntraeger", "email": "borntraeger@de.ibm.com", "time": "Wed Jan 11 11:20:30 2012 +0100" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Mon Mar 05 14:52:22 2012 +0200" }, "message": "KVM: provide synchronous registers in kvm_run\n\nOn some cpus the overhead for virtualization instructions is in the same\nrange as a system call.

These processors require a physically\ncontiguous, aligned area of memory for each guest. When the guest does\nan access in real mode (MMU off), the address is compared against a\nlimit value, and if it is lower, the address is ORed with an offset\nvalue (from the Real Mode Offset Register (RMOR)) and the result becomes\nthe real address for the access. The size of the RMA has to be one of\na set of supported values, which usually includes 64MB, 128MB, 256MB\nand some larger powers of 2.\n\nSince we are unlikely to be able to allocate 64MB or more of physically\ncontiguous memory after the kernel has been running for a while, we\nallocate a pool of RMAs at boot time using the bootmem allocator. The\nsize and number of the RMAs can be set using the kvm_rma_size\u003dxx and\nkvm_rma_count\u003dxx kernel command line options.\n\nKVM exports a new capability, KVM_CAP_PPC_RMA, to signal the availability\nof the pool of preallocated RMAs. The capability value is 1 if the\nprocessor can use an RMA but doesn\u0027t require one (because it supports\nthe VRMA facility), or 2 if the processor requires an RMA for each guest.\n\nThis adds a new ioctl, KVM_ALLOCATE_RMA, which allocates an RMA from the\npool and returns a file descriptor which can be used to map the RMA. It\nalso returns the size of the RMA in the argument structure.\n\nHaving an RMA means we will get multiple KMV_SET_USER_MEMORY_REGION\nioctl calls from userspace. To cope with this, we now preallocate the\nkvm-\u003earch.ram_pginfo array when the VM is created with a size sufficient\nfor up to 64GB of guest memory. Subsequently we will get rid of this\narray and use memory associated with each memslot instead.\n\nThis moves most of the code that translates the user addresses into\nhost pfns (page frame numbers) out of kvmppc_prepare_vrma up one level\nto kvmppc_core_prepare_memory_region. Also, instead of having to look\nup the VMA for each page in order to check the page size, we now check\nthat the pages we get are compound pages of 16MB. However, if we are\nadding memory that is mapped to an RMA, we don\u0027t bother with calling\nget_user_pages_fast and instead just offset from the base pfn for the\nRMA.\n\nTypically the RMA gets added after vcpus are created, which makes it\ninconvenient to have the LPCR (logical partition control register) value\nin the vcpu-\u003earch struct, since the LPCR controls whether the processor\nuses RMA or VRMA for the guest. This moves the LPCR value into the\nkvm-\u003earch struct and arranges for the MER (mediated external request)\nbit, which is the only bit that varies between vcpus, to be set in\nassembly code when going into the guest if there is a pending external\ninterrupt request.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n" }, { "commit": "371fefd6f2dc46668e00871930dde613b88d4bde", "tree": "35fe799343861405914d27873eb175eb04d6dce5", "parents": [ "54738c097163c3f01e67ccc85462b78d4d4f495f" ], "author": { "name": "Paul Mackerras", "email": "paulus@samba.org", "time": "Wed Jun 29 00:23:08 2011 +0000" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Tue Jul 12 13:16:57 2011 +0300" }, "message": "KVM: PPC: Allow book3s_hv guests to use SMT processor modes\n\nThis lifts the restriction that book3s_hv guests can only run one\nhardware thread per core, and allows them to use up to 4 threads\nper core on POWER7. The host still has to run single-threaded.\n\nThis capability is advertised to qemu through a new KVM_CAP_PPC_SMT\ncapability. The return value of the ioctl querying this capability\nis the number of vcpus per virtual CPU core (vcore), currently 4.\n\nTo use this, the host kernel should be booted with all threads\nactive, and then all the secondary threads should be offlined.\nThis will put the secondary threads into nap mode. KVM will then\nwake them from nap mode and use them for running guest code (while\nthey are still offline). To wake the secondary threads, we send\nthem an IPI using a new xics_wake_cpu() function, implemented in\narch/powerpc/sysdev/xics/icp-native.c. In other words, at this stage\nwe assume that the platform has a XICS interrupt controller and\nwe are using icp-native.c to drive it. Since the woken thread will\nneed to acknowledge and clear the IPI, we also export the base\nphysical address of the XICS registers using kvmppc_set_xics_phys()\nfor use in the low-level KVM book3s code.\n\nWhen a vcpu is created, it is assigned to a virtual CPU core.\nThe vcore number is obtained by dividing the vcpu number by the\nnumber of threads per core in the host. This number is exported\nto userspace via the KVM_CAP_PPC_SMT capability. If qemu wishes\nto run the guest in single-threaded mode, it should make all vcpu\nnumbers be multiples of the number of threads per core.\n\nWe distinguish three states of a vcpu: runnable (i.e., ready to execute\nthe guest), blocked (that is, idle), and busy in host. We currently\nimplement a policy that the vcore can run only when all its threads\nare runnable or blocked. This way, if a vcpu needs to execute elsewhere\nin the kernel or in qemu, it can do so without being starved of CPU\nby the other vcpus.\n\nWhen a vcore starts to run, it executes in the context of one of the\nvcpu threads. The other vcpu threads all go to sleep and stay asleep\nuntil something happens requiring the vcpu thread to return to qemu,\nor to wake up to run the vcore (this can happen when another vcpu\nthread goes from busy in host state to blocked).\n\nIt can happen that a vcpu goes from blocked to runnable state (e.g.\nbecause of an interrupt), and the vcore it belongs to is already\nrunning. In that case it can start to run immediately as long as\nthe none of the vcpus in the vcore have started to exit the guest.\nWe send the next free thread in the vcore an IPI to get it to start\nto execute the guest. It synchronizes with the other threads via\nthe vcore-\u003eentry_exit_count field to make sure that it doesn\u0027t go\ninto the guest if the other vcpus are exiting by the time that it\nis ready to actually enter the guest.\n\nNote that there is no fixed relationship between the hardware thread\nnumber and the vcpu number. Hardware threads are assigned to vcpus\nas they become runnable, so we will always use the lower-numbered\nhardware threads in preference to higher-numbered threads if not all\nthe vcpus in the vcore are runnable, regardless of which vcpus are\nrunnable.\n\nSigned-off-by: Paul Mackerras \u003cpaulus@samba.org\u003e\nSigned-off-by: Alexander Graf \u003cagraf@suse.de\u003e\n" }, { "commit": "54738c097163c3f01e67ccc85462b78d4d4f495f", "tree": "cba8d389d50251856cbe967c16ba2193a30d6d12", "parents": [ "a8606e20e41a8149456bafdf76ad29d47672027c" ], "author": { "name": "David Gibson", "email": "dwg@au1.ibm.com", "time": "Wed Jun 29 00:22:41 2011 +0000" }, "committer": { "name": "Avi Kivity", "email": "avi@redhat.com", "time": "Tue Jul 12 13:16:56 2011 +0300" }, "message": "KVM: PPC: Accelerate H_PUT_TCE by implementing it in real mode\n\nThis improves I/O performance for guests using the PAPR\nparavirtualization interface by making the H_PUT_TCE hcall faster, by\nimplementing it in real mode.

Using hypervisor mode means\nthat the guest can use the processor\u0027s supervisor mode. That means\nthat the guest can execute privileged instructions and access privileged\nregisters itself without trapping to the host. This gives excellent\nperformance, but does mean that KVM cannot emulate a processor\narchitecture other than the one that the hardware implements.\n\nThis code assumes that the guest is running paravirtualized using the\nPAPR (Power Architecture Platform Requirements) interface, which is the\ninterface that IBM\u0027s PowerVM hypervisor uses. That means that existing\nLinux distributions that run on IBM pSeries machines will also run\nunder KVM without modification. In order to communicate the PAPR\nhypercalls to qemu, this adds a new KVM_EXIT_PAPR_HCALL exit code\nto include/linux/kvm.h.\n\nCurrently the choice between book3s_hv support and book3s_pr support\n(i.e. the existing code, which runs the guest in user mode) has to be\nmade at kernel configuration time, so a given kernel binary can only\ndo one or the other.\n\nThis new book3s_hv code doesn\u0027t support MMIO emulation at present.\nSince we are running paravirtualized guests, this isn\u0027t a serious\nrestriction.\n\nWith the guest running in supervisor mode, most exceptions go straight\nto the guest. We will never get data or instruction storage or segment\ninterrupts, alignment interrupts, decrementer interrupts, program\ninterrupts, single-step interrupts, etc., coming to the hypervisor from\nthe guest. Therefore this introduces a new KVMTEST_NONHV macro for the\nexception entry path so that we don\u0027t have to do the KVM test on entry\nto those exception handlers.\n\nWe do however get hypervisor decrementer, hypervisor data storage,\nhypervisor instruction storage, and hypervisor emulation assist\ninterrupts, so we have to handle those.\n\nIn hypervisor mode, real-mode accesses can access all of RAM, not just\na limited amount. Therefore we put all the guest state in the vcpu.arch\nand use the shadow_vcpu in the PACA only for temporary scratch space.\nWe allocate the vcpu with kzalloc rather than vzalloc, and we don\u0027t use\nanything in the kvmppc_vcpu_book3s struct, so we don\u0027t allocate it.\nWe don\u0027t have a shared page with the guest, but we still need a\nkvm_vcpu_arch_shared struct to store the values of various registers,\nso we include one in the vcpu_arch struct.\n\nThe POWER7 processor has a restriction that all threads in a core have\nto be in the same partition. MMU-on kernel code counts as a partition\n(partition 0), so we have to do a partition switch on every entry to and\nexit from the guest. At present we require the host and guest to run\nin single-thread mode because of this hardware restriction.\n\nThis code allocates a hashed page table for the guest and initializes\nit with HPTEs for the guest\u0027s Virtual Real Memory Area (VRMA).
