2016-03-14hyperv: cpu hotplug fix with HyperV enabledDenis V. Lunev1-0/+1
With Hyper-V enabled CPU hotplug stops working. The CPU appears in device manager on Windows but does not appear in peformance monitor and control panel. The root of the problem is the following. Windows checks HV_X64_CPU_DYNAMIC_PARTITIONING_AVAILABLE bit in CPUID. The presence of this bit is enough to cure the situation. The bit should be set when CPU hotplug is allowed for HyperV VM. The check that hot_add_cpu callback is defined is enough from the protocol point of view. Though this callback is defined almost always thus there is no need to export that knowledge in the other way. Signed-off-by: Denis V.

2016-01-21target-i386: Add support to migrate vcpu's TSC rateHaozhong Zhang1-0/+9
This patch enables migrating vcpu's TSC rate. If KVM on the destination machine supports TSC scaling, guest programs will observe a consistent TSC rate across the migration. If TSC scaling is not supported on the destination machine, the migration will not be aborted and QEMU on the destination will not set vcpu's TSC rate to the migrated value. If vcpu's TSC rate specified by CPU option 'tsc-freq' on the destination machine is inconsistent with the migrated TSC rate, the migration will be aborted. For backwards compatibility, the migration of vcpu's TSC rate is disabled on pc-*-2.5 and older machine types.

Prevously, * the lack of TSC scaling never failed kvm_arch_init_vcpu(), * the failure of KVM_SET_TSC_KHZ failed kvm_arch_init_vcpu() unconditionally, even though the TSC rate to be set is identical to the value currently used by KVM.

2015-12-17target-i386: kvm: clear unusable segments' flags in migrationMichael Chapman1-9/+13
This commit fixes migration of a QEMU/KVM guest from kernel >= v3.9 to kernel <= v3.7 (e.g. from RHEL 7 to RHEL 6). Without this commit a guest migrated across these kernel versions fails to resume on the target host as its segment descriptors are invalid. Two separate kernel commits combined together to result in this bug: commit f0495f9b9992f80f82b14306946444b287193390 Author: Avi Kivity <avi@redhat.com> Date: Thu Jun 7 17:06:10 2012 +0300 KVM: VMX: Relax check on unusable segment Some userspace (e.g. QEMU 1.1) munge the d and g bits of segment descriptors, causing us not to recognize them as unusable segments with emulate_invalid_guest_state=1. Relax the check by testing for segment not present (a non-present segment cannot be usable).

Usability is returned in unusable field, so not need to clobber entire AR. Callers have to know how to deal with unusable segments already since if emulate_invalid_guest_state=true AR is not zeroed. Signed-off-by: Gleb Natapov <gleb@redhat.com> Signed-off-by: Marcelo Tosatti <mtosatti@redhat.com> The first commit changed the KVM_SET_SREGS ioctl so that it did no treat segment flags == 0 as an unusable segment, instead only looking at the "present" flag. The second commit changed KVM_GET_SREGS so that it did not clear the flags of an unusable segment. Since QEMU does not itself maintain the "unusable" flag across a migration, the end result is that unusable segments read from a kernel with these commits and loaded into a kernel without these commits are not properly recognised as being unusable. This commit updates both get_seg and set_seg so that the problem is avoided even when migrating to or migrating from a QEMU without this commit. In get_seg, we clear the segment flags if the segment is marked unusable. In set_seg, we mark the segment unusable if the segment's "present" flag is not set.

2015-12-17kvm: x86: add support for KVM_CAP_SPLIT_IRQCHIPPaolo Bonzini1-2/+40
This patch adds support for split IRQ chip mode. When KVM_CAP_SPLIT_IRQCHIP is enabled: 1.) The PIC, PIT, and IOAPIC are implemented in userspace while the LAPIC is implemented by KVM. 2.) The software IOAPIC delivers interrupts to the KVM LAPIC via kvm_set_irq. Interrupt delivery is configured via the MSI routing table, for which routes are reserved in target-i386/kvm.c then configured in hw/intc/ioapic.c 3.) KVM delivers IOAPIC EOIs via a new exit KVM_EXIT_IOAPIC_EOI, which is handled in target-i386/kvm.c and relayed to the software IOAPIC via ioapic_eoi_broadcast.

2015-11-26target-i386: kvm: Abort if MCE bank count is not supported by hostEduardo Habkost1-3/+6
Instead of silently changing the number of banks in mcg_cap based on kvm_get_mce_cap_supported(), abort initialization if the host doesn't support MCE_BANKS_DEF banks. Note that MCE_BANKS_DEF was always 10 since it was introduced in QEMU, and Linux always returned 32 at KVM_CAP_MCE since KVM_CAP_MCE was introduced, so no behavior is being changed and the error can't be triggered by any Linux version. The point of the new check is to ensure we won't silently change the bank count if we change MCE_BANKS_DEF or make the bank count configurable in the future.

The commit 317b0a6d8 fixed an issue which caused by the outdated env->tsc value, but the fix lead to 'cpu_synchronize_all_states()' called twice during live migration. The 'cpu_synchronize_all_states()' takes about 130us for a VM which has 4 vcpus, it's a bit expensive. Synchronize the whole CPU context just for updating env->tsc is too wasting, this patch use a new function to update the env->tsc.

2015-01-26target-i386: make xmm_regs 512-bit widePaolo Bonzini1-16/+24
Right now, the AVX512 registers are split in many different fields: xmm_regs for the low 128 bits of the first 16 registers, ymmh_regs for the next 128 bits of the same first 16 registers, zmmh_regs for the next 256 bits of the same first 16 registers, and finally hi16_zmm_regs for the full 512 bits of the second 16 bit registers. This makes it simple to move data in and out of the xsave region, but would be a nightmare for a hypothetical TCG implementation and leads to a proliferation of [XYZ]MM_[BWLSQD] macros. Instead, this patch marshals data manually from the xsave region to a single 32x512-bit array, simplifying the macro jungle and clarifying which bits are in which vmstate subsection. The migration format is unaffected. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2015-01-14target-i386: do not memcpy in and out of xmm_regsPaolo Bonzini1-6/+24
After the next patch, we will move the high parts of AVX and AVX512 registers in the same array as the SSE registers. This will make it impossible to memcpy an array of 128-bit values in and out of xmm_regs in one swoop. Use a for loop instead. Similarly, always use XMM_Q in translate.c. This avoids introducing bugs such as the one fixed in the previous patch. Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-01-12kvm: extend kvm_irqchip_add_msi_route to work on s390Frank Blaschka1-0/+6
on s390 MSI-X irqs are presented as thin or adapter interrupts for this we have to reorganize the routing entry to contain valid information for the adapter interrupt code on s390. To minimize impact on existing code we introduce an architecture function to fixup the routing entry.

2014-12-15x86: Use g_new() & friends where that makes obvious senseMarkus Armbruster1-1/+1
g_new(T, n) is neater than g_malloc(sizeof(T) * n). It's also safer, for two reasons. One, it catches multiplication overflowing size_t. Two, it returns T * rather than void *, which lets the compiler catch more type errors. This commit only touches allocations with size arguments of the form sizeof(T).
