2014-06-27spapr_pci: Use XICS interrupt allocator and do not cache interrupts in PHBAlexey Kardashevskiy
Currently SPAPR PHB keeps track of all allocated MSI (here and below MSI stands for both MSI and MSIX) interrupt because XICS used to be unable to reuse interrupts. This is a problem for dynamic MSI reconfiguration which happens when guest reloads a driver or performs PCI hotplug. Another problem is that the existing implementation can enable MSI on 32 devices maximum (SPAPR_MSIX_MAX_DEVS=32) and there is no good reason for that. This makes use of new XICS ability to reuse interrupts. This reorganizes MSI information storage in sPAPRPHBState. Instead of static array of 32 descriptors (one per a PCI function), this patch adds a GHashTable when @config_addr is a key and (first_irq, num) pair is a value. GHashTable can dynamically grow and shrink so the initial limit of 32 devices is gone. This changes migration stream as @msi_table was a static array while new @msi_devs is a dynamic hash table. This adds temporary array which is used for migration, it is populated in "spapr_pci"::pre_save() callback and expanded into the hash table in post_load() callback. Since the destination side does not know the number of MSI-enabled devices in advance and cannot pre-allocate the temporary array to receive migration state, this makes use of new VMSTATE_STRUCT_VARRAY_ALLOC macro which allocates the array automatically. This resets the MSI configuration space when interrupts are released by the ibm,change-msi RTAS call. This fixed traces to be more informative. This changes vmstate_spapr_pci_msi name from "...lsi" to "...msi" which was incorrect by accident. As the internal representation changed, thus bumps migration version number.

2014-06-27spapr: Move interrupt allocator to xicsAlexey Kardashevskiy
The current allocator returns IRQ numbers from a pool and does not support IRQs reuse in any form as it did not keep track of what it previously returned, it only keeps the last returned IRQ. Some use cases such as PCI hot(un)plug may require IRQ release and reallocation. This moves an allocator from SPAPR to XICS. This switches IRQ users to use new API. This uses LSI/MSI flags to know if interrupt is allocated. The interrupt release function will be posted as a separate patch.

2014-06-16spapr_iommu: Enable multiple TCE requestsAlexey Kardashevskiy
Currently only single TCE entry per request is supported (H_PUT_TCE). However PAPR+ specification allows multiple entry requests such as H_PUT_TCE_INDIRECT and H_STUFF_TCE. Having less transitions to the host kernel via ioctls, support of these calls can accelerate IOMMU operations. This implements H_STUFF_TCE and H_PUT_TCE_INDIRECT. This advertises "multi-tce" capability to the guest if the host kernel supports it (KVM_CAP_SPAPR_MULTITCE) or guest is running in TCG mode.

2014-06-16spapr: Implement processor compatibility in ibm, client-architecture-supportAlexey Kardashevskiy
Modern Linux kernels support last POWERPC CPUs so when a kernel boots, in most cases it can find a matching cpu_spec in the kernel's cpu_specs list. However if the kernel is quite old, it may be missing a definition of the actual CPU. To provide an ability for old kernels to work on modern hardware, a Processor Compatibility Mode has been introduced by the PowerISA specification. >From the hardware prospective, it is supported by the Processor Compatibility Register (PCR) which is defined in PowerISA. The register enables one of the compatibility modes (2.05/2.06/2.07). Since PCR is a hypervisor privileged register and cannot be directly accessed from the guest, the mode selection is done via ibm,client-architecture-support (CAS) RTAS call using which the guest specifies what "raw" and "architected" CPU versions it supports. QEMU works out the best match, changes a "cpu-version" property of every CPU and notifies the guest about the change by setting these properties in the buffer passed as a response on a custom H_CAS hypercall. This implements ibm,client-architecture-support parameters parsing (now only for PVRs) and cooks the device tree diff with new values for "cpu-version", "ibm,ppc-interrupt-server#s" and "ibm,ppc-interrupt-server#s" properties.

2014-06-16spapr: Add ibm, client-architecture-support callAlexey Kardashevskiy
The PAPR+ specification defines a ibm,client-architecture-support (CAS) RTAS call which purpose is to provide a negotiation mechanism for the guest and the hypervisor to work out the best compatibility parameters. During the negotiation process, the guest provides an array of various options and capabilities which it supports, the hypervisor adjusts the device tree and (optionally) reboots the guest. At the moment the Linux guest calls CAS method at early boot so SLOF gets called. SLOF allocates a memory buffer for the device tree changes and calls a custom KVMPPC_H_CAS hypercall. QEMU parses the options, composes a diff for the device tree, copies it to the buffer provided by SLOF and returns to SLOF. SLOF updates the device tree and returns control to the guest kernel. Only then the Linux guest parses the device tree so it is possible to avoid unnecessary reboot in most cases. The device tree diff is a header with an update format version (defined as 1 in this patch) followed by a device tree with the properties which require update. If QEMU detects that it has to reboot the guest, it silently does so as the guest expects reboot to happen because this is usual pHyp firmware behavior. This defines custom KVMPPC_H_CAS hypercall. The current SLOF already has support for it. This implements stub which returns very basic tree (root node, no properties) to the guest. As the return buffer does not contain any change, no change in behavior is expected. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: Alexander Graf <agraf@suse.de>
2014-06-16spapr: Add support for time base offset migrationAlexey Kardashevskiy
This allows guests to have a different timebase origin from the host. This is needed for migration, where a guest can migrate from one host to another and the two hosts might have a different timebase origin. However, the timebase seen by the guest must not go backwards, and should go forwards only by a small amount corresponding to the time taken for the migration. This is only supported for recent POWER hardware which has the TBU40 (timebase upper 40 bits) register. That includes POWER6, 7, 8 but not 970. This adds kvm_access_one_reg() to access a special register which is not in env->spr. This requires kvm_set_one_reg/kvm_get_one_reg patch. The feature must be present in the host kernel. This bumps vmstate_spapr::version_id and enables new vmstate_ppc_timebase only for it. Since the vmstate_spapr::minimum_version_id remains unchanged, migration from older QEMU is supported but without vmstate_ppc_timebase.

2014-06-10s390x/kvm: enable/reset cmma via vm attributesDominik Dingel
Exploit the new api for userspace-controlled cmma. If supported, enable cmma during kvm initialization and register a reset handler for cmma, which is also called directly from the load IPL code. The reset functionality is needed to reset the cmma state of the guest pages, e.g. if a system reset is triggered via qemu monitor; otherwise this could result in data corruption. A guest triggered reboot may now lead to multiple cmma resets; this is OK, however, as this is slowpath anyway and the simplest way to achieve the intended effects.

2014-01-16usb: add support for microsoft os descriptorsGerd Hoffmann
This patch adds support for special usb descriptors used by microsoft windows. They allow more fine-grained control over driver binding and adding entries to the registry for configuration. As this is a guest-visible change the "msos-desc" compat property has been added to turn this off for 1.7 + older Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2013-12-03raw-posix: implement write_zeroes with MAY_UNMAP for filesPaolo Bonzini
Writing zeroes to a file can be done by punching a hole if MAY_UNMAP is set. Note that in this case ENOTSUP is not ignored, but makes the block layer fall back to the generic implementation. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
