2015-07-07xics_kvm: Don't enable KVM_CAP_IRQ_XICS if already enabledBharata B Rao1-0/+1
When supporting CPU hot removal by parking the vCPU fd and reusing it during hotplug again, there can be cases where we try to reenable KVM_CAP_IRQ_XICS CAP for the vCPU for which it was already enabled. Introduce a boolean member in ICPState to track this and don't reenable the CAP if it was already enabled earlier. Re-enabling this CAP should ideally work, but currently it results in kernel trying to create and associate ICP with this vCPU and that fails since there is already an ICP associated with it. Hence this patch is needed to work around this problem in the kernel. This change allows CPU hot removal to work for sPAPR.

2015-07-07spapr: Remove obsolete entry_point field from sPAPRMachineStateDavid Gibson1-1/+1
The sPAPRMachineState structure includes an entry_point field containing the initial PC value for starting the machine, even though this always has the value 0x100. I think this is a hangover from very early versions which bypassed the firmware when using -kernel. In any case it has no function now, so remove it.

2015-07-07spapr: Remove obsolete ram_limit field from sPAPRMachineStateDavid Gibson1-1/+0
The ram_limit field was imported from sPAPREnvironment where it predates the machine's ram size being available generically from machine->ram_size. Worse, the existing code was inconsistent about where it got the ram size from. Sometimes it used spapr->ram_limit, sometimes the global 'ram_size' and sometimes a local 'ram_size' masking the global. This cleans up the code to consistently use machine->ram_size, eliminating spapr->ram_limit in the process.

2015-07-07spapr: Merge sPAPREnvironment into sPAPRMachineStateDavid Gibson3-14/+33
The code for -machine pseries maintains a global sPAPREnvironment structure which keeps track of general state information about the guest platform. This predates the existence of the MachineState structure, but performs basically the same function. Now that we have the generic MachineState, fold sPAPREnvironment into sPAPRMachineState, the pseries specific subclass of MachineState. This is mostly a matter of search and replace, although a few places which relied on the global spapr variable are changed to find the structure via qdev_get_machine().

2015-07-07i386: Introduce ARAT CPU featureJan Kiszka1-1/+6
ARAT signals that the APIC timer does not stop in power saving states. As our APICs are emulated, it's fine to expose this feature to guests, at least when asking for KVM host features or with CPU types that include the flag. The exact model number that introduced the feature is not known, but reports can be found that it's at least available since Sandy Bridge.

2015-07-07migration: create new section to store global stateJuan Quintela1-0/+1
This includes a new section that for now just stores the current qemu state. Right now, there are only one way to control what is the state of the target after migration. - If you run the target qemu with -S, it would start stopped. - If you run the target qemu without -S, it would run just after migration finishes. The problem here is what happens if we start the target without -S and there happens one error during migration that puts current state as -EIO. Migration would ends (notice that the error happend doing block IO, network IO, i.e. nothing related with migration), and when migration finish, we would just "continue" running on destination, probably hanging the guest/corruption data, whatever.

2015-07-06vfio/pci : Add pba_offset PCI quirk for Chelsio T5 devicesGabriel Laupre1-0/+2
Fix pba_offset initialization value for Chelsio T5 Virtual Function device. The T5 hardware has a bug in it where it reports a Pending Interrupt Bit Array Offset of 0x8000 for its SR-IOV Virtual Functions instead of the 0x1000 that the hardware actually uses internally. As the hardware doesn't return the correct pba_offset value, add a quirk to instead return a hardcoded value of 0x1000 when a Chelsio T5 VF device is detected. This bug has been fixed in the Chelsio's next chip series T6 but there are no plans to respin the T5 ASIC for this bug. It is just documented in the T5 Errata and left it at that.

Currently the "host" page size alignment API is really aligning to both host and target page sizes. There is the qemu_real_page_size which can be used for the actual host page size but it's missing a mask and ALIGN macro as provided for qemu_page_size. Complete the API. This allows system level code that cares about the host page size to use a consistent alignment interface without having to un-needingly align to the target page size.

2015-07-06Stop including qemu-common.h in memory.hPeter Maydell5-4/+21
Including qemu-common.h from other header files is generally a bad idea, because it means it's very easy to end up with a circular dependency. For instance, if we wanted to include memory.h from qom/cpu.h we'd end up with this loop: memory.h -> qemu-common.h -> cpu.h -> cpu-qom.h -> qom/cpu.h -> memory.h Remove the include from memory.h. This requires us to fix up a few other files which were inadvertently getting declarations indirectly through memory.h. The biggest change is splitting the fprintf_function typedef out into its own header so other headers can get at it without having to include qemu-common.h.

2015-07-03numa: API to lookup NUMA node by addressBharata B Rao1-0/+1
Introduce an API numa_get_node(ram_addr_t addr, Error **errp) that returns the NUMA node to which the given address belongs to. This API works uniformly for both boot time as well as hotplugged memory. This API is needed by sPAPR PowerPC to support ibm,dynamic-reconfiguration-memory device tree node which is needed for memory hotplug.

2015-07-03numa,pc-dimm: Store pc-dimm memory information in numa_infoBharata B Rao1-0/+10
Start storing the (start_addr, end_addr) of the pc-dimm memory in corresponding numa_info[node] so that this information can be used to lookup node by address.

2015-07-03pc,pc-dimm: Factor out reusable parts in pc_dimm_plug to a separate routineBharata B Rao1-0/+4
pc_dimm_plug() has code that will be needed for memory plug handlers in other archs too. Extract code from pc_dimm_plug() into a generic routine pc_dimm_memory_plug() that resides in pc-dimm.c. Also correspondingly refactor re-usable unplug code into pc_dimm_memory_unplug().

2015-07-02block: Remove bdrv_reset_dirtyFam Zheng1-2/+0
Using this function would always be wrong because a dirty bitmap must have a specific owner that consumes the dirty bits and calls bdrv_reset_dirty_bitmap(). Remove the unused function to avoid future misuse.

[Initialized bdrv_co_get_block_status_above() ret to 0 to silence mingw64 compiler warning about the unitialized variable. assert(bs != base) prevents that case but I suppose the program could be compiled with -DNDEBUG. --Stefan] Signed-off-by: Fam Zheng <famz@redhat.com> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>
