2013-07-29fdc: Fix inheritence for SUNW,fdtwoAndreas Färber
Since commit dd3be7420774f7dc8f37a96ca24d07f0b6f31b3b SUNW,fdtwo's initfn (realizefn since 940194c2369e50d91d1abf6f36d43853eea5e539) was using SYSBUS_FDC() cast. This uses type sysbus-fdc rather than SUNW,fdtwo. Fix this by letting SUNW,fdtwo and sysbus-fdc both inherit from an abstract type base-sysbus-fdc. This allows to consolidate realizefns by using instance_init functions. Clean up variable names and variable order while at it.

2013-07-29spapr-vscsi: fix SOLNT bit in SRP_RSPAlexey Kardashevskiy
The driver calculates SOLNT bit from UCSOLNT and SCSOLNT bits from the request. The iu pointer has a type of srp_iu* which points to a union, so cmd and rsp overlap. As the vscsi_send_rsp function calls memset(iu, 0, sizeof(rsp)), it clears first 36 bytes of both cmd and rsp so cmd.sol_not is always zero at the moment of calculating rsp.sol_not. This fixes the bug. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Message-id: 1375073319-17488-1-git-send-email-aik@ozlabs.ru Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-07-29xics: rename types to be sane and follow coding styleAnthony Liguori
Basically, in HW the layout of the interrupt network is: - One ICP per processor thread (the "presenter"). This contains the registers to fetch a pending interrupt (ack), EOI, and control the processor priority. - One ICS per logical source of interrupts (ie, one per PCI host bridge, and a few others here or there). This contains the per-interrupt source configuration (target processor(s), priority, mask) and the per-interrupt internal state. Under PAPR, there is a single "virtual" ICS ... somewhat (it's a bit oddball what pHyp does here, arguably there are two but we can ignore that distinction). There is no register level access. A pair of firmware (RTAS) calls is used to configure each virtual interrupt. So our model here is somewhat the same. We have one ICS in the emulated XICS which arguably *is* the emulated XICS, there's no point making it a separate "device", that would just be gross, and each VCPU has an associated ICP. Yet we call the "XICS" struct icp_state and then the ICPs 'struct icp_server_state'. It's particularly confusing when all of the functions have xics_prefixes yet take *icp arguments.

2013-07-29pseries: savevm support with KVMAlexey Kardashevskiy
At present, the savevm / migration support for the pseries machine will not work when KVM is enabled. That's because KVM manages the guest's hash page table in the host kernel, so qemu has no visibility of it. This patch fixes this by using new kernel interfaces to extract and reinsert the guest's hash table during the migration process.

2013-07-29pseries: savevm support for pseries machineDavid Gibson
This adds the necessary pieces to implement savevm / migration for the pseries machine. The most complex part here is migrating the hash table - for the paravirtualized pseries machine the guest's hash page table is not stored within guest memory, but externally and the guest accesses it via hypercalls. This patch uses a hypervisor reserved bit of the HPTE as a dirty bit (tracking changes to the HPTE itself, not the page it references). This is used to implement a live migration style incremental save and restore of the hash table contents. Normally a hash table is 16MB but it can get bigger depending on how much RAM the guest has. Due to its nature, updates to it are random so the live migration style is used for it. In addition it adds VMStateDescription information to save and restore the (few) remaining pieces of state information needed by the pseries machine.

2013-07-29pseries: rework PAPR virtual SCSIAlexey Kardashevskiy
The patch reimplements handling of indirect requests in order to simplify upcoming live migration support. - all pointers (except SCSIRequest*) were replaces with integer indexes and offsets; - DMA'ed srp_direct_buf kept untouched (ie. BE format); - vscsi_fetch_desc() is added, now it is the only place where descriptors are fetched and byteswapped; - vscsi_req struct fields converted to migration-friendly types; - many dprintf()'s fixed. This also removed an unused field 'lun' from the spapr_vscsi device which is assigned, but never used. So, remove it.

2013-07-29dataplane: refuse to start if device is already in useStefan Hajnoczi
Dataplane must check whether a block device is in use before launching the dataplane thread. This is necessary since the thread does not synchronize with the main loop and I/O requests could cause corruption. One example is when a drive is added and a block job is started before hotplugging the virtio-blk-pci adapter. In this case we must not use dataplane mode.

2013-07-29xen_disk: support "direct-io-safe" backend optionStefano Stabellini
Support backend option "direct-io-safe". This is documented as follows in the Xen backend specification: * direct-io-safe * Values: 0/1 (boolean) * Default Value: 0 * * The underlying storage is not affected by the direct IO memory * lifetime bug. See: * http://lists.xen.org/archives/html/xen-devel/2012-12/msg01154.html * * Therefore this option gives the backend permission to use * O_DIRECT, notwithstanding that bug. * * That is, if this option is enabled, use of O_DIRECT is safe, * in circumstances where we would normally have avoided it as a * workaround for that bug. This option is not relevant for all * backends, and even not necessarily supported for those for * which it is relevant. A backend which knows that it is not * affected by the bug can ignore this option. * * This option doesn't require a backend to use O_DIRECT, so it * should not be used to try to control the caching behaviour. Also, BDRV_O_NATIVE_AIO is ignored if BDRV_O_NOCACHE, so clarify the default flags passed to the qemu block layer. The original proposal for a "cache" backend option has been dropped because it was believed too wide, especially considering that at the moment the backend doesn't have a way to tell the toolstack that it is capable of supporting it.

On real hardware this results in the status byte being mirrored in the upper 16 bits of the read value. For example if the status byte is represented by SS then the hardware reads 0x00SS00SS.
