2018-03-09pci: Add support for Designware IP blockAndrey Smirnov2-0/+756
Add code needed to get a functional PCI subsytem when using in conjunction with upstream Linux guest (4.13+). Tested to work against "e1000e" (network adapter, using MSI interrupts) as well as "usb-ehci" (USB controller, using legacy PCI interrupts).

2017-12-15e500: fix pci host bridge class/typeMichael Davidsaver1-5/+0
Correct some confusion wrt. the PCI facing side of the PCI host bridge (not PCIe root complex). The ref. manual for the mpc8533 (as well as mpc8540 and mpc8540) give the class code as PCI_CLASS_PROCESSOR_POWERPC. While the PCI_HEADER_TYPE field is oddly omitted, the tables in the "PCI Configuration Header" section shows a type 0 layout using all 6 BAR registers (as 2x 32, and 2x 64 bit regions) So 997505065dc92e533debf5cb23012ba4e673d387 seems to be in error. Although there was perhaps some confusion as the mpc8533 has a separate PCIe root complex. With PCIe, a root complex has PCI_HEADER_TYPE=1. Neither the PCI host bridge, nor the PCIe root complex advertise class PCI_CLASS_BRIDGE_PCI. This was confusing Linux guests, which try to interpret the host bridge as a pci-pci bridge, but get confused and re-enumerate the bus when the primary/secondary/subordinate bus registers don't have valid values.

Currently there is no MMIO range over 4G reserved for PCI hotplug. Since the 32bit PCI hole depends on the number of cold-plugged PCI devices and other factors, it is very possible is too small to hotplug PCI devices with large BARs. Fix it by reserving 2G for I4400FX chipset in order to comply with older Win32 Guest OSes and 32G for Q35 chipset. Even if the new defaults of pci-hole64-size will appear in "info qtree" also for older machines, the property was not implemented so no changes will be visible to guests. Note this is a regression since prev QEMU versions had some range reserved for 64bit PCI hotplug.

2017-10-19sun4u: update PCI topology to include simba PCI bridgesMark Cave-Ayland1-11/+36
This patch updates the sun4u model to being much closer to a real Ultra 5 by moving devices behind the 2 simba PCI bridges (A and B) as found on real hardware. The most noticeable change introduced by this patchset is that in-built devices are no longer attached to the PCI root bus, but instead behind PCI bridge A. Along with this the interrupt routing is updated accordingly to match the official documentation. Since the existing code currently bypasses the PCI bridge interrupt swizzling, the interrupt mapping functions are reorganised so that pci_pbm_map_irq() is used by the PCI bridges and pci_apb_map_irq() is used by the PCI host bridge. Behind the sabre PCI host bridge, the PCI IO space now needs to be split into two separate halves at 0x8000000. Therefore we also setup a new PCI IO space region of increased size on the PCI host bridge and enable 32-bit PCI IO accesses to allow IO accesses to reach devices behind PCI bridge B correctly. As part of this change we also combine the onboard sunhme NIC and the ebus into a single multi-function device as done on a real Ultra 5. For other NICs the existing behaviour is preserved, i.e. we initialise them and place them into the next free slot on PCI bus B. Finally we mark the physically unavailable slots (plus slot 0 in busA) as reserved to ensure that users can't plug devices into non-existent slots which will break interrupt routing. Note: since this commit changes PCI topology and interrupt routing, an updated openbios-sparc64 binary is included with this commit containing the associated changes to maintain bisectability.

2017-10-15pci: Add INTERFACE_CONVENTIONAL_PCI_DEVICE to Conventional PCI devicesEduardo Habkost10-0/+60
Add INTERFACE_CONVENTIONAL_PCI_DEVICE to all direct subtypes of TYPE_PCI_DEVICE, except: 1) The ones that already have INTERFACE_PCIE_DEVICE set: * base-xhci * e1000e * nvme * pvscsi * vfio-pci * virtio-pci * vmxnet3 2) base-pci-bridge Not all PCI bridges are Conventional PCI devices, so INTERFACE_CONVENTIONAL_PCI_DEVICE is added only to the subtypes that are actually Conventional PCI: * dec-21154-p2p-bridge * i82801b11-bridge * pbm-bridge * pci-bridge The direct subtypes of base-pci-bridge not touched by this patch are: * xilinx-pcie-root: Already marked as PCIe-only. * pcie-pci-bridge: Already marked as PCIe-only. * pcie-port: all non-abstract subtypes of pcie-port are already marked as PCIe-only devices. 3) megasas-base Not all megasas devices are Conventional PCI devices, so the interface names are added to the subclasses registered by megasas_register_types(), according to information in the megasas_devices[] array. "megasas-gen2" already implements INTERFACE_PCIE_DEVICE, so add INTERFACE_CONVENTIONAL_PCI_DEVICE only to "megasas".

2017-09-27migration: pre_save return intDr. David Alan Gilbert1-1/+3
Modify the pre_save method on VMStateDescription to return an int rather than void so that it potentially can fail. Changed zillions of devices to make them return 0; the only case I've made it return non-0 is hw/intc/s390_flic_kvm.c that already had an error_report/return case. Note: If you add an error exit in your pre_save you must emit an error_report to say why.

2017-09-14hw/pci-host/gpex: Implement PCI INTx routingPranavkumar Sawargaonkar1-0/+12
Now we are able to retrieve the gsi from the INTx pin, let's enable intx_to_irq routing. From that point on, irqfd becomes usable along with INTx when assigning a PCIe device.

2017-09-14hw/pci-host/gpex: Set INTx index/gsi mappingPranavkumar Sawargaonkar1-0/+10
To implement INTx to gsi routing we need to pass the gpex host bridge the gsi associated to each INTx index. Let's introduce irq_num array and gpex_set_irq_num setter function.

2017-09-04apb: add busA qdev property to PBM PCI bridgeMark Cave-Ayland1-7/+37
As future sun4u PCI topologies place the ebus containing the in-built devices behind a PCI bridge, add a busA property to the PBM PCI bridge that is then used to allow IO accesses by default. This allows early fw_cfg/NVRAM/serial access to occur even before OpenBIOS has had a chance to configure the PCI bridges. Signed-off-by: Mark Cave-Ayland <mark.cave-ayland@ilande.co.uk>

2017-09-04apb: fix up PCI bus nomenclatureMark Cave-Ayland1-7/+5
Rather than referring to the PCI busses as bus2 and bus3, refer to them as busA and busB as per the documentation. Also replace the long bus names with the shorter pciA and pciB aliases (to make it easier to attach additional devices to either from the command line).
