2013-09-16lsi: add 53C810 variantHervé Poussineau1-0/+1
Currently, treat it exactly as a 53C895A. 53C895A is a 53C810 with more capabilities, so this should work. However, this lets us test different code paths on Linux, which don't use lastest features if it detect a 810, or on some OSes which only support 810 and not 895A (like very old Windows NT versions).

2013-09-06e1000: add interrupt mitigation supportVincenzo Maffione1-0/+8
This patch partially implements the e1000 interrupt mitigation mechanisms. Using a single QEMUTimer, it emulates the ITR register (which is the newer mitigation register, recommended by Intel) and approximately emulates RADV and TADV registers. TIDV and RDTR register functionalities are not emulated (RDTR is only used to validate RADV, according to the e1000 specs). RADV, TADV, TIDV and RDTR registers make up the older e1000 mitigation mechanism and would need a timer each to be completely emulated. However, a single timer has been used in order to reach a good compromise between emulation accuracy and simplicity/efficiency. The implemented mechanism can be enabled/disabled specifying the command line e1000-specific boolean parameter "mitigation", e.g. qemu-system-x86_64 -device e1000,mitigation=on,... ... For more information, see the Software developer's manual at http://download.intel.com/design/network/manuals/8254x_GBe_SDM.pdf. Interrupt mitigation boosts performance when the guest suffers from an high interrupt rate (i.e. receiving short UDP packets at high packet rate).

2013-09-02spapr-pci: rework MSI/MSIXAlexey Kardashevskiy2-4/+8
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.

2013-09-01pc: reduce duplication, fix PIIX descriptionsMichael S. Tsirkin1-0/+8
We have a lot of code duplication between machine types, this increases with each new machine type and each new field. This has already introduced a minor bug: description for pc-1.3 says "Standard PC" while description for pc-1.4 is "Standard PC (i440FX + PIIX, 1996)" which makes you think 1.3 is somehow more standard, or newer, while in fact it's a revision of the same PC. This patch addresses this issue by using macros, along the lines used by PC_COMPAT_X_X - only for non-property options. The approach can extend to non-PC machine types.

2013-08-28hw: Clean up bogus default boot orderMarkus Armbruster1-5/+2
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.

2013-08-27pc: fix regression for 64 bit PCI memoryMichael S. Tsirkin1-1/+10
commit 398489018183d613306ab022653552247d93919f pc: limit 64 bit hole to 2G by default introduced a way for management to control the window allocated to the 64 bit PCI hole. This is useful, but existing management tools do not know how to set this property. As a result, e.g. specifying a large ivshmem device with size > 4G is broken by default. For example this configuration no longer works: -device ivshmem,size=4294967296,chardev=cfoo -chardev socket,path=/tmp/sock,id=cfoo,server,nowait Fix this by detecting that hole size was not specified and defaulting to the backwards-compatible value of 1 << 62.

2013-08-27pci: Introduce helper to retrieve a PCI device's DMA address spaceAlexey Kardashevskiy1-0/+1
A PCI device's DMA address space (possibly an IOMMU) is returned by a method on the PCIBus. At the moment that only has one caller, so the method is simply open coded. We'll need another caller for VFIO, so this patch introduces a helper/wrapper function. If IOMMU is not set, the pci_device_iommu_address_space() function returns the parent's IOMMU skipping the "bus master" address space as otherwise proper emulation would require more effort for no benefit.

2013-08-21loader: store FW CFG ROM files in RAMMichael S. Tsirkin1-0/+1
ROM files that are put in FW CFG are copied to guest ram, by BIOS, but they are not backed by RAM so they don't get migrated. Each time we change two bytes in such a ROM this breaks cross-version migration: since we can migrate after BIOS has read the first byte but before it has read the second one, getting an inconsistent state. Future-proof this by creating, for each such ROM, an MR serving as the backing store. This MR is never mapped into guest memory, but it's registered as RAM so it's migrated with the guest. Naturally, this only helps for -M 1.7 and up, older machine types will still have the cross-version migration bug. Luckily the race window for the problem to trigger is very small, which is also likely why we didn't notice the cross-version migration bug in testing yet. Signed-off-by: Michael S.

2013-07-29xics: rename types to be sane and follow coding styleAnthony Liguori2-8/+69
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 Kardashevskiy1-0/+1
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 Gibson1-3/+9
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.

2013-07-29spapr-tce: make sPAPRTCETable a proper deviceAnthony Liguori1-7/+16
Model TCE tables as a device that's hooked up as a child object to the owner. Besides the code cleanup, we get a few nice benefits: 1) free actually works now (it was dead code before) 2) the TCE information is visible in the device tree 3) we can expose table information as properties such that if we change the window_size, we can use globals to keep migration working.
