The xilinx host driver does the same host registration and bus scanning calls as pci_host_probe, so let's use it instead. The only difference is pci_assign_unassigned_bus_resources() was called instead of pci_bus_size_bridges() and pci_bus_assign_resources(). This should be the same.

2020-07-06PCI: vmd: Use Shadow MEMBAR registers for QEMU/KVM guestsJon Derrick1-6/+38
VMD device 28C0 natively assists guest passthrough of the VMD endpoint through the use of shadow registers that provide Host Physical Addresses to correctly assign bridge windows. These shadow registers are only available if VMD config space register 0x70, bit 1 is set. In order to support this mode in existing VMD devices which don't natively support the shadow register, it was decided that the hypervisor could offer the shadow registers in a vendor-specific PCI capability. QEMU has been modified to create this vendor-specific capability and supply the shadow membar registers for VMDs which don't natively support this feature. This patch adds this mode and updates the supported device list to allow this feature to be used on these VMDs.

2020-06-01PCI: tegra: Fix runtime PM imbalance on errorDinghao Liu1-2/+1
pm_runtime_get_sync() increments the runtime PM usage counter even when it returns an error code. Thus a pairing decrement is needed on the error handling path to keep the counter balanced. Also, call pm_runtime_disable() when pm_runtime_get_sync() returns an error code.

2020-05-29PCI: vmd: Filter resource type bits from shadow registerJon Derrick1-2/+4
Versions of VMD with the Host Physical Address shadow register use this register to calculate the bus address offset needed to do guest passthrough of the domain. This register shadows the Host Physical Address registers including the resource type bits. After calculating the offset, the extra resource type bits lead to the VMD resources being over-provisioned at the front and under-provisioned at the back. Example: pci 10000:80:02.0: reg 0x10: [mem 0xf801fffc-0xf803fffb 64bit] Expected: pci 10000:80:02.0: reg 0x10: [mem 0xf8020000-0xf803ffff 64bit] If other devices are mapped in the over-provisioned front, it could lead to resource conflict issues with VMD or those devices.
