2014-06-19pc: implement pc-dimm device abstractionVasilis Liaskovitis
Each hotplug-able memory slot is a PCDIMMDevice. A hot-add operation for a memory device: - creates a new PCDIMMDevice and makes hotplug controller to map it into guest address space Hotplug operations are done through normal device_add commands. For migration case, all hotplugged memory devices on source should be specified on target's command line using '-device' option with properties set to the same values as on source. To simplify review, patch introduces only PCDIMMDevice QOM skeleton that will be extended by following patches to implement actual memory hotplug and related functions.

2014-06-18hw/mips/cputimer: Don't start periodic timer in KVM modeSanjay Lal
Compare/Count timer interrupts are handled in-kernel for KVM. Therefore don't bother creating the timer at init time if KVM is enabled. This will conveniently avoid attempts to set the timeout when cpu_mips_store_count() is called at reset with KVM enabled, treating the timer as stopped so that CP0_Count is modified directly.

2014-06-18target-mips: Reset CPU timer consistentlyJames Hogan
The MIPS CPU timer (CP0 Count/Compare registers & QEMU timer) is reset at machine initialisation, including starting the timeout. Both registers however are placed before mvp in CPUMIPSState so they will both be zeroed on reset by the memset in mips_cpu_reset() including soon after init. This doesn't take into account that the timer may be running, in which case env->CP0_Count will represent the delta against the VM clock and the timeout will need updating. At init time (cpu_mips_clock_init()), lets only create the timer. Setting Count = 1 and starting the timer (cpu_mips_store_count()) can be done at reset time from cpu_state_reset(), which is after the memset. There is also no need to set CP0_Compare = 0 as that is already handled by the memset. Note that a reset occurs from mips_cpu_realizefn() which is before the machine init callback has had a chance to set up the CPU interrupts and the CPU timer, so env->timer will be NULL. This case is handled explicitly in cpu_mips_store_count(), treating the timer as disabled (which will also be the right thing to do when KVM support is added).

2014-06-16spapr_pci: Advertise MSI quotaBadari Pulavarty
Hotplug of multiple disks fails due to MSI vector quota check. Number of MSI vectors default to 8 allowing only 4 devices. This happens on RHEL6.5 guest. RHEL7 and SLES11 guests fallback to INTX. One way to workaround the issue is to increase total MSIs, so that MSI quota check allows us to hotplug multiple disks. This sets the quota to the maximum number of interupts XICS has which is 1024 now (XICS_IRQS). This moves XICS_IRQS from spapr.c to xics.h for wider visibility.

PR KVM supports an ePAPR compliant hypercall interface in parallel to the normal sPAPR one. Expose the ePAPR /hypervisor node and properties to the guest so it can use it. This enables magic page sharing on PR KVM with -M pseries. However we had a few nasty bugs in the magic page implementation on vcpus newer than 970 (p7, p8) that KVM now has workarounds for. It indicates that it does have these workarounds through the PPC_FIXUP_HCALL capability. To not expose broken guest kernels to issues on host kernels that don't have the fixups in place, we don't expose working hypercall instructions when the fixups are not available so that the guest can never active the magic page.
