# HG changeset patch # User kfraser@xxxxxxxxxxxxxxxxxxxxx # Node ID df80de098d1577600b31aa8b9713c61a0df6668f # Parent 8cd5771109048d31fc650615073abe7ad6388772 [PCI] Two policy files written in what is intended to be human-readable SXP. 1. xend-pci-quirks.sxp: Specifies which PCI device(s) may write to a set of PCI configuration space registers. A quirky PCI device is identified by its vendor ID, device ID, subvendor ID, and subdevice ID. If a matching entry is found, the corresponding fields will be sent to the PCI bus manager. Fields are composed of a register, size, and mask -- although the mask field is currently unused. The included policy file is for a range of tg3 devices, which is the only type of quirky device I know about. Users with other quirky devices are invited to either add entries to this policy file or add an entry in the permissive file, described next. In either case, send an email to the xen-devel list to make the device known. 2. xend-pci-permissive.sxp Lists PCI devices that pciback should not prevent from writing to their configuration space. This can be necessary if, for example, a new Tigon3 devices is released with different PCI vendor/device values such that no entry in xend-pci-quirks.sxp is triggered.
