* Add function to convert a PCI device "tag" into a PCIe requester ID.kettenis2018-07-281-2/+3

* Make it possible for graphics drivers to opt-out of VGA arbitration.kettenis2013-08-081-1/+2
| | | | | | | | | | | | The idea is that as soon the kernel driver switches out of vga text mode, it can disable decoding of legacy vga io and mmio and call pci_disable_legacy_vga() to take itself out of arbitration. The PCIGETVGA ioctl is extended such that it returns the legacy decoding state of a device. The X server can then query this state for all graphics devices in the system (through libpciaccess) and decide whether it needs to do arbitration. ok jsg@

* Set a first step on the road towards proper accounting of PCI resources bykettenis2009-04-061-1/+11
| | | | | | | | | | | | keeping a per-bus extent containing the address space available to the bus. Address space assigned to devices will be removed from these extents when we attach a bus. And when we try to map a PCI BAR that hasn't had address space assigned to it, we will allocate free space from this extent. This won't do anything until the parent devices actually allocate and initialize the extents. ok oga@

* Implement deep interrupt swizzling by mapping all four PCI interrupt pinskettenis2007-05-211-1/+4
| | | | | | | | | | for PCI-PCI bridges and passing the mapping to the attached bus device. MD code can use these when mapping PCI device interrupts. This diff adds such code for amd64 and i386. This fixes interrupt mapping for devices that sit behind two PCI-PCI bridges where the firmware only provides a mapping for the first PCI-PCI bridge. tested by sturm@, krw@, and a few others, ok deraadt@

* Provide a new function, pci_findproduct(), which is analog to pci_findvendor().mbalmer2007-01-021-1/+2
| | | | | | | | | | | Use these two functions in pci_devinfo() to remove some duplicated code and make it easier to read. Remove two now unused variables. This shrinks the size of the resulting object code. Drivers (or other kernel code) can now get at the PCI vendor and/or product strings using pci_findvendor() and pci_findproduct(). ok claudio, deraadt, mglocker

* rev 1.86brad2006-03-191-2/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | make the "generic" PCI bus enumeration code the standard case which gets used if nothing else is defined in MD headers, introduce a "PCI_MACHDEP_ENUMERATE_BUS" CPP definition which can be used by MD headers (just 1 port atm) to plug in special code rev 1.62 * Implement a machine-dependent pci_enumerate_bus() for sparc64 which uses OFW device nodes to enumerate the bus. When a PCI bus that is behind a bridge is attached, pci_attach_hook() allocates a new PCI chipset tag for the new bus and sets it's "curnode" to the OFW node of the bridge. This is used as a starting point when enumerating that bus. Root busses get the OFW node of the host bridge (psycho). rev 1.59 Split the code that enumerates the PCI bus and that actually probes for a device into two functions: * pci_probe_device() actually probes/attaches the device specified by the provide pcitag_t. * pci_enumerate_bus() enumerates the bus, and calls pci_probe_device() for each device on the bus. A pci_enumerate_bus_generic() is provided which implements the old method of doing this: If something found at dev0/func0, determine number of functions and probe each one. From NetBSD ok kettenis@ Tested on a good number of amd64/i386/macppc/sparc64 systems
