Most of the almost-identical versions of pci_mmap_page_range() silently ignore the 'write_combine' argument and give uncached mappings. Yet we allow the PCIIOC_WRITE_COMBINE ioctl in /proc/bus/pci, expose the 'resourceX_wc' file in sysfs, and allow an attempted mapping to apparently succeed. To fix this, introduce a macro arch_can_pci_mmap_wc() which indicates whether the platform can do a write-combining mapping. On x86 this ends up being pat_enabled(), while the few other platforms that support it can just set it to a literal '1'.

NVLink is a high speed interconnect that is used in conjunction with a PCI-E connection to create an interface between CPU and GPU that provides very high data bandwidth. A PCI-E connection to a GPU is used as the control path to initiate and report status of large data transfers sent via the NVLink. On IBM Power systems the NVLink processing unit (NPU) is similar to the existing PHB3. This patch adds support for a new NPU PHB type. DMA operations on the NPU are not supported as this patch sets the TCE translation tables to be the same as the related GPU PCIe device for each NVLink. Therefore all DMA operations are setup and controlled via the PCIe device. EEH is not presently supported for the NPU devices, although it may be added in future.

They are required by the shim in order to return a sensible default. Previously, the were defined in pci.h, but pci.h includes pci-bridge.h before the relevant #defines. This means the definitions are absent if pci.h is included before pci-bridge.h. This occurs in some drivers. So, move the definitons now, and move them back when we remove the shim.

Until now, the MSI architecture-specific functions could be overloaded using a fairly complex set of #define and compile-time conditionals. In order to prepare for the introduction of the msi_chip infrastructure, it is desirable to switch all those functions to use the 'weak' mechanism. This commit converts all the architectures that were overidding those MSI functions to use the new strategy. Note that we keep two separate, non-weak, functions default_teardown_msi_irqs() and default_restore_msi_irqs() for the default behavior of the arch_teardown_msi_irqs() and arch_restore_msi_irqs(), as the default behavior is needed by x86 PCI code.

This patch converts PowerPC's architecture-specific 'pcibios_set_master()' routine to a non-inlined function. This will allow follow on patches to create a generic 'pcibios_set_master()' function using the '__weak' attribute which can be used by all architectures as a default which, if necessary, can then be over- ridden by architecture-specific code. Converting 'pci_bios_set_master()' to a non-inlined function will allow PowerPC's 'pcibios_set_master()' implementation to remain architecture-specific after the generic version is introduced and thus, not change current behavior.

由 Benjamin Herrenschmidt 提交于
powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

This patch moves the of_node pointer into (struct pci_bus*)->dev.of_node and (struct pci_dev*)->dev.of_node so that sysdata can be converted to always use the pci_controller pointer instead.

The PCI device tree scanning code in pci_64.c is some useful functionality. It allows PCI devices to be described in the device tree instead of being probed for, which in turn allows pci devices to use all of the device tree facilities to describe complex PCI bus architectures like GPIO and IRQ routing (perhaps not a common situation for desktop or server systems, but useful for embedded systems with on-board PCI devices).

Currently, our PCI code uses the pcibios_fixup_bus() callback, which is called by the generic code when probing PCI buses, for two different things. One is to set up things related to the bus itself, such as reading bridge resources for P2P bridges, fixing them up, or setting up the iommu's associated with bridges on some platforms. The other is some setup for each individual device under that bridge, mostly setting up DMA mappings and interrupts. The problem is that this approach doesn't work well with PCI hotplug when an existing bus is re-probed for new children. We fix this problem by splitting pcibios_fixup_bus into two routines: pcibios_setup_bus_self() is now called to setup the bus itself pcibios_setup_bus_devices() is now called to setup devices pcibios_fixup_bus() is then modified to call these two after reading the bridge bases, and the OF based PCI probe is modified to avoid calling into the first one when rescanning an existing bridge.

We essentially adopt the 64-bit dma code, with some changes to support 32-bit systems, including HIGHMEM. dma functions on 32-bit are now invoked via accessor functions which call the correct op for a device based on archdata dma_ops. If there is no archdata dma_ops, this defaults to dma_direct_ops. In addition, the dma_map/unmap_page functions are added to dma_ops because we can't just fall back on map/unmap_single when HIGHMEM is enabled. In the case of dma_direct_*, we stop using map/unmap_single and just use the page version - this saves a lot of ugly ifdeffing. We leave map/unmap_single in the dma_ops definition, though, because they are needed by the iommu code, which does not implement map/unmap_page. Ideally, going forward, we will completely eliminate map/unmap_single and just have map/unmap_page, if it's workable for 64-bit.

The 32 bits PCI code now uses the generic code for assigning unassigned resources and an algorithm similar to x86 for claiming existing ones. This works far better than the 64 bits code which basically can only claim existing ones (pci_probe_only=1) or would fall apart completely. This merges them so that the new 32 bits implementation is used for both. 64 bits now gets the new PCI flags for controlling the behaviour, though the old pci_probe_only global is still there for now to be cleared if you want to. I kept a pcibios_claim_one_bus() function mostly based on the old 64 bits code for use by the DLPAR hotplug. This will have to be cleaned up, thought I hope it will work in the meantime.

The PCI code in 32 and 64 bits fixes up resources differently. 32 bits uses a header quirk plus handles bridges in pcibios_fixup_bus() while 64 bits does things in various places depending on whether you are using OF probing, using PCI hotplug, etc... This merges those by basically using the 32 bits approach for both, with various tweaks to make 64 bits work with the new approach.
