2013-10-25spapr: Use DeviceClass::fw_name for device tree CPU nodeAndreas Färber
Instead of relying on cpu_model, obtain the device tree node label per CPU. Use DeviceClass::fw_name as source. Whenever DeviceClass::fw_name is unknown, default to "PowerPC,UNKNOWN". As a consequence, spapr_fixup_cpu_dt() can operate on each CPU's fw_name, obsoleting sPAPREnvironment::cpu_model, and spapr_create_fdt_skel() can drop its cpu_model argument.

2013-10-25spapr-pci: enable irqfd for INTxAlexey Kardashevskiy
This enables IRQFD for LSI (level triggered INTx interrupts) by adding a spapr_route_intx_pin_to_irq() callback to the sPAPR PCI host bus. This callback is called to know the global interrupt number to link resampling fd with IRQFD's fd in KVM.

2013-10-25xics-kvm: Support for in-kernel XICS interrupt controllerDavid Gibson
Recent (host) kernels support emulating the PAPR defined "XICS" interrupt controller system within KVM. This patch allows qemu to initialize and configure the in-kernel XICS, and keep its state in sync with qemu's XICS state as necessary. This should give considerable performance improvements. e.g. on a simple IPI ping-pong test between hardware threads, using qemu XICS gives us around 5,000 irqs/second, whereas the in-kernel XICS gives us around 70,000 irqs/s on the same hardware configuration.

2013-10-25xics: split to xics and xics-commonAlexey Kardashevskiy
The upcoming XICS-KVM support will use bits of emulated XICS code. So this introduces new level of hierarchy - "xics-common" class. Both emulated XICS and XICS-KVM will inherit from it and override class callbacks when required. The new "xics-common" class implements: 1. replaces static "nr_irqs" and "nr_servers" properties with the dynamic ones and adds callbacks to be executed when properties are set. 2. xics_cpu_setup() callback renamed to xics_common_cpu_setup() as it is a common part for both XICS'es 3. xics_reset() renamed to xics_common_reset() for the same reason. The emulated XICS changes: 1. the part of xics_realize() which creates ICPs is moved to the "nr_servers" property callback as realize() is too late to create/initialize devices and instance_init() is too early to create devices as the number of child devices comes via the "nr_servers" property. 2. added ics_initfn() which does a little part of what xics_realize() did.

2013-09-02spapr-pci: rework MSI/MSIXAlexey Kardashevskiy
On the sPAPR platform a guest allocates MSI/MSIX vectors via RTAS hypercalls which return global IRQ numbers to a guest so it only operates with those and never touches MSIMessage. Therefore MSIMessage handling is completely hidden in QEMU. Previously every sPAPR PCI host bridge implemented its own MSI window to catch msi_notify()/msix_notify() calls from QEMU devices (virtio-pci or vfio) and route them to the guest via qemu_pulse_irq(). MSIMessage used to be encoded as: .addr - address within the PHB MSI window; .data - the device index on PHB plus vector number. The MSI MR write function translated this MSIMessage to a global IRQ number and called qemu_pulse_irq(). However the total number of IRQs is not really big (at the moment it is 1024 IRQs starting from 4096) and even 16bit data field of MSIMessage seems to be enough to store an IRQ number there. This simplifies MSI handling in sPAPR PHB. Specifically, this does: 1. remove a MSI window from a PHB; 2. add a single memory region for all MSIs to sPAPREnvironment and spapr_pci_msi_init() to initialize it; 3. encode MSIMessage as: * .addr - a fixed address of SPAPR_PCI_MSI_WINDOW==0x40000000000ULL; * .data as an IRQ number. 4. change IRQ allocator to align first IRQ number in a block for MSI. MSI uses lower bits to specify the vector number so the first IRQ has to be aligned. MSIX does not need any special allocator though.

spapr-pci config space accessors use find_dev() to find a PCI device. However find_dev() only searched on a primary bus and did not do recursive search through secondary buses so config space access was not possible for devices other that on a primary bus. This fixed find_dev() by using the PCI API pci_find_device() function. This effectively enabled pci bridges on spapr. Signed-off-by: Alexey Kardashevskiy <aik@ozlabs.ru> Acked-by: Michael S.

2013-09-02PPC: E500: Generate device tree on resetAlexander Graf
Today we generate the device tree once on machine initialization and then store the finalized blob in memory to reload it on reset. This is bad for 2 reasons. First we potentially waste a bunch of RAM for no good reason, as we have all information required to regenerate the device tree available anyways. The second reason is even more important. On machine init when we generate the device tree for the first time, we don't have all of the devices fully initialized yet. But the device tree needs to potentially walk devices to put information about them into the device tree. Move the generation into a reset function. That way we just generate it new every time we reset, solving both of the above issues. Signed-off-by: Alexander Graf <agraf@suse.de>

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster
We set default boot order "cad" in every single machine definition except "pseries" and "moxiesim", even though very few boards actually care for boot order, and "cad" makes sense for even fewer. Machines that care: * pc and its variants Accept up to three letters 'a', 'b' (undocumented alias for 'a'), 'c', 'd' and 'n'. Reject all others (fatal with -boot). * nseries (n800, n810) Check whether order starts with 'n'. Silently ignored otherwise. * prep, g3beige, mac99 Extract the first character the machine understands (subset of 'a'..'f'). Silently ignored otherwise. * spapr Accept an arbitrary string (vl.c restricts it to contain only 'a'..'p', no duplicates). * sun4[mdc] Use the first character. Silently ignored otherwise. Strip characters these machines ignore from their default boot order. For all other machines, remove the unused default boot order alltogether. Note that my rename of QEMUMachine member boot_order to default_boot_order and QEMUMachineInitArgs member boot_device to boot_order has a welcome side effect: it makes every use of boot orders visible in this patch, for easy review.

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 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.
