This patch denies crossing the boundary of the pages in the replay mode, because it can cause an exception. Do it only when boundary is crossed by the first instruction in the block. If current instruction already crossed the bound - it's ok, because an exception hasn't stopped this code.

This patch introduces new QEMU_CLOCK_VIRTUAL_RT clock, which should be used for icount warping.

In icount mode cpu_exec_nocache function is used to execute part of the existing TB. At the end of cpu_exec_nocache newly created TB is deleted. Sometimes io_read function needs to recompile current TB and restart TB lookup and execution. After that tb_find_fast function finds old (bigger) TB again. This TB cannot be executed (because icount is not big enough) and cpu_exec_nocache is called again. Such a loop continues over and over. This patch deletes old TB and avoids finding it in the TB cache. Signed-off-by: NPavel Dovgalyuk <Pavel.Dovgaluk@ispras.ru> Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

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).

These represent xsave-related capabilities of the processor, and KVM may or may not support them. Add feature bits so that they are considered by "-cpu ...,enforce", and use the new feature work instead of calling kvm_arch_get_supported_cpuid. Bit 3 (XSAVES) is not migratables because it requires saving MSR_IA32_XSS. Neither KVM nor any commonly available hardware supports it anyway. Signed-off-by: NPaolo Bonzini <pbonzini@redhat.com>

Paolo Bonzini reported that Coverity reports an uninitialized pad value. Let's use a designated initializer for kvm_irq_routing_entry to avoid this false positive.

struct kvm_msrs contains padding bytes. Let's use a designated initializer on the info part to avoid false positives from valgrind/memcheck. Do the same for generic MSRS, the TSC and feature control. We also need to zero out the reserved fields in the entries. We do this in kvm_msr_entry_set as suggested by Paolo. This avoids a big memset that a designated initializer on the full structure would do.

Compute kvm_irqfds_allowed by checking the KVM_CAP_IRQFD extension. Remove direct settings in architecture specific files. Add a new kvm_resamplefds_allowed variable, initialized by checking the KVM_CAP_IRQFD_RESAMPLE extension. Add a corresponding kvm_resamplefds_enabled() function. A special notice for s390 where KVM_CAP_IRQFD was not immediatly advirtised when irqfd capability was introduced in the kernel. KVM_CAP_IRQ_ROUTING was advertised instead. This was fixed in "KVM: s390: announce irqfd capability", ebc3226202d5956a5963185222982d435378b899 whereas irqfd support was brought in 84223598778ba08041f4297fda485df83414d57e, "KVM: s390: irq routing for adapter interrupts". Both commits first appear in 3.15 so there should not be any kernel version impacted by this QEMU modification.

If QEMU is started with -numa ... Windows only notices that CPU has been hot-added but it will not online such CPUs. It's caused by the fact that possible CPUs are flagged as not enabled in SRAT and Windows honoring that information doesn't use corresponding CPU. ACPI 5.0 Spec regarding to flag says: " Table 5-47 Local APIC Flags ... Enabled: if zero, this processor is unusable, and the operating system support will not attempt to use it. " Fix QEMU to adhere to spec and mark possible CPUs as enabled in SRAT. With that Windows onlines hot-added CPUs as expected.
