2014-06-16spapr_iommu: Enable multiple TCE requestsAlexey Kardashevskiy1-0/+2
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 Kardashevskiy1-0/+4
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 Kardashevskiy1-0/+4
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 Kardashevskiy1-0/+3
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 Dingel1-0/+4
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.

Some ONE_REGS on s390 are not protected by a capability. Older kernels might not provide those and return an error. Fortunately these registers are only critical for the migration path. There is no need to error out on reset and normal runtime. Furthermore, these kernels don't provide a proper dirty bitmap anyway, so let's use tracing for those errors. Also provide generic one reg helper to simplify the code.
