2016-06-07spapr_pci: Add and export DMA resetting helperAlexey Kardashevskiy1-0/+2
This will be later used by the "ibm,reset-pe-dma-window" RTAS handler which resets the DMA configuration to the defaults. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Reviewed-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2016-06-07spapr_iommu: Add root memory regionAlexey Kardashevskiy1-1/+1
We are going to have multiple DMA windows at different offsets on a PCI bus. For the sake of migration, we will have as many TCE table objects pre-created as many windows supported. So we need a way to map windows dynamically onto a PCI bus when migration of a table is completed but at this stage a TCE table object does not have access to a PHB to ask it to map a DMA window backed by just migrated TCE table. This adds a "root" memory region (UINT64_MAX long) to the TCE object. This new region is mapped on a PCI bus with enabled overlapping as there will be one root MR per TCE table, each of them mapped at 0. The actual IOMMU memory region is a subregion of the root region and a TCE table enables/disables this subregion and maps it at the specific offset inside the root MR which is 1:1 mapping of a PCI address space.

2016-06-07spapr_iommu: Migrate full stateAlexey Kardashevskiy1-0/+3
The source guest could have reallocated the default TCE table and migrate bigger/smaller table. This adds reallocation in post_load() if the default table size is different on source and destination. This adds @bus_offset, @page_shift to the migration stream as a subsection so when DDW is added, migration to older machines will still be possible. As @bus_offset and @page_shift are not used yet, this makes no change in behavior. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
2016-06-07spapr_iommu: Introduce "enabled" state for TCE tableAlexey Kardashevskiy1-5/+4
Currently TCE tables are created once at start and their sizes never change. We are going to change that by introducing a Dynamic DMA windows support where DMA configuration may change during the guest execution. This changes spapr_tce_new_table() to create an empty zero-size IOMMU memory region (IOMMU MR). Only LIOBN is assigned by the time of creation. It still will be called once at the owner object (VIO or PHB) creation. This introduces an "enabled" state for TCE table objects, some helper functions are added: - spapr_tce_table_enable() receives TCE table parameters, stores in sPAPRTCETable and allocates a guest view of the TCE table (in the user space or KVM) and sets the correct size on the IOMMU MR; - spapr_tce_table_disable() disposes the table and resets the IOMMU MR size; it is made public as the following DDW code will be using it. This changes the PHB reset handler to do the default DMA initialization instead of spapr_phb_realize(). This does not make differenct now but later with more than just one DMA window, we will have to remove them all and create the default one on a system reset. No visible change in behaviour is expected except the actual table will be reallocated every reset. We might optimize this later. The other way to implement this would be dynamically create/remove the TCE table QOM objects but this would make migration impossible as the migration code expects all QOM objects to exist at the receiver so we have to have TCE table objects created when migration begins.

2016-05-26memory: Fix IOMMU replay base addressAlexey Kardashevskiy1-0/+1
Since a788f227 "memory: Allow replay of IOMMU mapping notifications" when new VFIO listener is added, all existing IOMMU mappings are replayed. However there is a problem that the base address of an IOMMU memory region (IOMMU MR) is ignored which is not a problem for the existing user (which is pseries) with its default 32bit DMA window starting at 0 but it is if there is another DMA window. This stores the IOMMU's offset_within_address_space and adjusts the IOVA before calling vfio_dma_map/vfio_dma_unmap. As the IOMMU notifier expects IOVA offset rather than the absolute address, this also adjusts IOVA in sPAPR H_PUT_TCE handler before calling notifier(s).

2016-05-20pc-dimm: correct comment of MemoryHotplugStateCao jin1-3/+1
correct comment and remove an unused macro. commit adcb4ee6 already correct its type Signed-off-by: Cao jin <caoj.fnst@cn.fujitsu.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
2016-05-19hw: clean up hw/hw.h includesPaolo Bonzini2-3/+3
Include qom/object.h and exec/memory.h instead of exec/ioport.h; exec/ioport.h was almost everywhere required only for those two includes, not for the content of the header itself. Remove block/aio.h, everybody is already including it through another path. With this change, include/hw/hw.h is freed from qemu-common.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19hw: remove pio_addr_tPaolo Bonzini1-2/+2
pio_addr_t is almost unused, because these days I/O ports are simply accessed through the address space. cpu_{in,out}[bwl] themselves are almost unused; monitor.c and xen-hvm.c could use address_space_read/write directly, since they have an integer size at hand. This leaves qtest as the only user of those functions. On the other hand even portio_* functions use this type; the only interesting use of pio_addr_t thus is include/hw/sysbus.h. I guess I could move it there, but I don't see much benefit in that either. Using uint32_t is enough and avoids the need to include ioport.h everywhere.

2016-05-19hw: explicitly include qemu/log.hPaolo Bonzini1-1/+0
Move the inclusion out of hw/hw.h, most files do not need it. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19qemu-common: push cpu.h inclusion out of qemu-common.hPaolo Bonzini7-4/+10

2016-05-19s390x: reorganize CSS bits between cpu.h and other headersPaolo Bonzini2-0/+387
Move cpu_inject_* to the only C file where they are used. Move ioinst.h declarations that need S390CPU to cpu.h, to make ioinst.h independent of cpu.h. Move channel declarations that only need SubchDev from cpu.h to css.h, to make more channel users independent of cpu.h.

2016-05-19qemu-common: stop including qemu/host-utils.h from qemu-common.hPaolo Bonzini1-7/+0
Move it to the actual users. There are some inclusions of qemu/host-utils.h in headers, but they are all necessary. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19hw: cannot include hw/hw.h from user emulationPaolo Bonzini2-3/+4
All qdev definitions are available from other headers, user-mode emulation does not need hw/hw.h. By considering system emulation only, it is simpler to disentangle hw/hw.h from NEED_CPU_H. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19hw: move CPU state serialization to migration/cpu.hPaolo Bonzini1-49/+0
Remove usage of NEED_CPU_H from hw/hw.h. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2016-05-19hw: do not use VMSTATE_*TLPaolo Bonzini1-1/+1
Reserve this to CPU state serialization. Luckily, they were only used by sPAPR devices and these are ppc64 only. So there is no change to migration format. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
