2017-01-03aio: add AioPollFn and io_poll() interfaceStefan Hajnoczi
The new AioPollFn io_poll() argument to aio_set_fd_handler() and aio_set_event_handler() is used in the next patch. Keep this code change separate due to the number of files it touches.

2017-01-03aio: add flag to skip fds to aio_dispatch()Stefan Hajnoczi
Polling mode will not call ppoll(2)/epoll_wait(2). Therefore we know there are no fds ready and should avoid looping over fd handlers in aio_dispatch().

2016-12-27target-arm: Add VBAR support to ARM1176 CPUsCédric Le Goater
ARM1176 CPUs have TrustZone support and can use the Vector Base Address Register, but currently, qemu only adds VBAR support to ARMv7 CPUs. Fix this by adding a new feature ARM_FEATURE_VBAR which can used for ARMv7 and ARM1176 CPUs.

2016-12-27hw/intc/arm_gicv3: Don't signal Pending+Active interrupts to CPUPeter Maydell
The GICv3 requires that we only signal Pending interrupts to the CPU. This category does not include Pending+Active interrupts, which means we need to check whether the interrupt is Active in the gicr_int_pending() and gicd_int_pending() functions. Interrupts are rarely in the Active+Pending state, but KVM uses this as part of its handling of the virtual timer, so this bug was causing KVM to go into an infinite loop of taking the vtimer interrupt when the guest first triggered it.

2016-12-27hw/intc/arm_gicv3: Remove incorrect usage of fieldoffsetPeter Maydell
In the ARMCPRegInfo definitions for the GICv3 CPU interface registers, we were trying to use .fieldoffset to specify the locations of data fields within the GICv3CPUState struct. This is completely broken, because .fieldoffset is for offsets into the CPUARMState struct. We didn't notice because we were only using this for reads to BPR0, AP0R<n>, IGRPEN0 and CTLR_EL3, and Linux doesn't use these registers. Replace the .fieldoffset uses with explicit read functions.

2016-12-27Correct value of ARM Cortex-A8 MVFR1 register.Julian Brown
The value of the MVFR1 (Media and VFP Feature Register 1) register for the Cortex-A8 appears to be incorrect (according to the TRM, DDI0344K), with the "full denormal arithmetic" and "propagation of NaN" fields holding both 0 instead of both 1. I had a go tracing the history of the use of this value, and it seems it's always just been wrong in QEMU: maybe it was derived from early documentation, or guessed based on the use of a "VFP Lite" implementation in the Cortex-A8. Depending on the startup/early-boot code in use, this can manifest as failure to perform denormal arithmetic properly: in our case, selecting a Cortex-A8 CPU when using QEMU as an instruction-set simulator for bare-metal GCC testing caused tests using denormal arithmetic to fail. Problems might be masked (or not occur) when using a full OS kernel with suitable trap handlers (I'm not sure).

2016-12-22x86: implement la57 paging modeKirill A. Shutemov
The new paging more is extension of IA32e mode with more additional page table level. It brings support of 57-bit vitrual address space (128PB) and 52-bit physical address space (4PB). The structure of new page table level is identical to pml4. The feature is enumerated with CPUID.(EAX=07H, ECX=0):ECX[bit 16]. CR4.LA57[bit 12] need to be set when pageing enables to activate 5-level paging mode. Signed-off-by: Kirill A.

2016-12-22target-i386: Fix eflags.TF/#DB handling of syscall/sysret insnsDoug Evans
The syscall and sysret instructions behave a bit differently: TF is checked after the instruction completes. This allows the o/s to disable #DB at a syscall by adding TF to FMASK. And then when the sysret is executed the #DB is taken "as if" the syscall insn just completed.

2016-12-22kvmclock: reduce kvmclock difference on migrationMarcelo Tosatti
Check for KVM_CAP_ADJUST_CLOCK capability KVM_CLOCK_TSC_STABLE, which indicates that KVM_GET_CLOCK returns a value as seen by the guest at that moment. For new machine types, use this value rather than reading from guest memory. This reduces kvmclock difference on migration from 5s to 0.1s (when max_downtime == 5s).
