2014-02-10hw/pci: switch to a generic hotplug handling for PCIDeviceIgor Mammedov2-12/+0
make qdev_unplug()/device_set_realized() to call hotplug handler's plug/unplug methods if available and remove not needed anymore hot(un)plug handling from PCIDevice. In case if hotplug handler is not available, revert to the legacy hotplug method for compatibility with not yet converted buses.

2013-12-01xen-pvdevice: make device-id property compulsoryPaul Durrant1-1/+0
The intention of the Xen PV device is that it is used as a parent device for PV drivers in Xen HVM guests and the set of PV drivers that bind to the device is determined by its device ID (and possibly vendor ID and revision). As such, the device should not have a default device ID, it should always be supplied by the Xen toolstack.

2013-11-10Revert "hw/pci: partially handle pci master abort"Marcel Apfelbaum1-1/+0
This reverts commit a53ae8e934cd54686875b5bcfc2f434244ee55d6. The patch being reverted introduced a low-priority memory region covering all 64 bit pci address space. This exposed the following bugs elsewhere in the code: 1. Some memory regions have INT64_MAX size, where the intent was all 64 bit address space. This results in a sub-page region, should be UINT64_MAX. 2. page table rendering in exec.c ignores physical address bits above TARGET_PHYS_ADDR_SPACE_BITS. Access outside this range (e.g. from device DMA, or gdb stub) ends up with a wrong region. Registering a region outside this range leads to page table corruption. 3. Some regions overlap PCI hole and have same priority. This only works as long as no device uses the overlapping address. It doesn't look like we can resolve all issues in time for 1.7. Let's fix the bugs first and apply afterwards for 1.8. Signed-off-by: Marcel Apfelbaum <marcel.a@redhat.com> Reviewed-by: Michael S. Tsirkin <mst@redhat.com> Signed-off-by: Michael S.

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.

2013-07-07pci: Add root bus parameter to pci_nic_init()David Gibson1-2/+4
At present, pci_nic_init() and pci_nic_init_nofail() assume that they will only create a NIC under the primary PCI root. As we add support for multiple PCI roots, that may no longer be the case. This patch adds a root bus parameter to pci_nic_init() (and updates callers accordingly) to allow the machine init code using it to specify the right PCI root for NICs created by old-style -net nic parameters. NICs created new-style, with -device can of course be put anywhere. Signed-off-by: David Gibson <david@gibson.dropbear.id.au> Signed-off-by: Michael S. Tsirkin <mst@redhat.com>
2013-07-07pci: Add root bus argument to pci_get_bus_devfn()David Gibson1-1/+1
pci_get_bus_devfn() interprets a full PCI address string to give a PCIBus * and device/function number within that bus. Currently it assumes it is working on an address under the primary PCI root bus. This patch extends it to allow the caller to specify a root bus. This might seem a little odd since the supplied address can (theoretically) include a PCI domain number. However, attempting to use a non-zero domain number there is currently an error, so that shouldn't really cause problems.

2013-07-07pci: Replace pci_find_domain() with more general pci_root_bus_path()David Gibson2-1/+11
pci_find_domain() is used in a number of places where we want an id for a whole PCI domain (i.e. the subtree under a PCI root bus). The trouble is that many platforms may support multiple independent host bridges with no hardware supplied notion of domain number. This patch, therefore, replaces calls to pci_find_domain() with calls to a new pci_root_bus_path() returning a string. The new call is implemented in terms of a new callback in the host bridge class, so it can be defined in some way that's well defined for the platform. When no callback is available we fall back on the qbus name. Most current uses of pci_find_domain() are for error or informational messages, so the change in identifiers should be harmless. The exception is pci_get_dev_path(), whose results form part of migration streams. To maintain compatibility with old migration streams, the PIIX PCI host is altered to always supply "0000" for this path, which matches the old domain number (since the code didn't actually support domains other than 0). For the pseries (spapr) PCI bridge we use a different platform-unique identifier (pseries machines can routinely have dozens of PCI host bridges). Theoretically that breaks migration streams, but given that we don't yet have migration support for pseries, it doesn't matter. Any other machines that have working migration support including PCI devices will need to be updated to maintain migration stream compatibility.

2013-07-07pci: Use helper to find device's root bus in pci_find_domain()David Gibson1-1/+2
Currently pci_find_domain() performs two functions - it locates the PCI root bus above the given bus, then looks up that root bus's domain number. This patch adds a helper function to perform the first task, finding the root bus for a given PCI device. This is then used in pci_find_domain(). This changes pci_find_domain()'s signature slightly, taking a PCIDevice instead of a PCIBus - since all callers passed something of the form dev->bus, this simplifies things slightly.

2013-07-07pci: Abolish pci_find_root_bus()David Gibson1-1/+1
pci_find_root_bus() takes a domain parameter. Currently PCI root buses with domain other than 0 can't be created, so this is more or less a long winded way of retrieving the main PCI root bus. Numbered domains don't actually properly cover the (non x86) possibilities for multiple PCI root buses, so this patch for now enforces the domain == 0 restriction in other places to replace pci_find_root_bus() with an explicit pci_find_primary_bus().

2013-04-08hw: move headers to include/Paolo Bonzini15-0/+2465
Many of these should be cleaned up with proper qdev-/QOM-ification. Right now there are many catch-all headers in include/hw/ARCH depending on cpu.h, and this makes it necessary to compile these files per-target. However, fixing this does not belong in these patches.
