dca: registering requesters in multiple dca domains This patch enables DCA support on multiple-IOH/multiple-IIO architectures. It modifies dca module by replacing single dca_providers list with dca_domains list, each domain containing separate list of providers. This approach lets dca driver manage multiple domains, i.e. sets of providers and requesters mapped back to the same PCI root complex device. The driver takes care to register each requester to a provider from the same domain.

I/OAT: I/OAT version 3.0 support This patch adds to ioatdma and dca modules support for Intel I/OAT DMA engine ver.3 (aka CB3 device). The main features of I/OAT ver.3 are: * 8 single channel DMA devices (8 channels total) * 8 DCA providers, each can accept 2 requesters * 8-bit TAG values and 32-bit extended APIC IDs Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>

DCA: Add Direct Cache Access driver Direct Cache Access (DCA) is a method for warming the CPU cache before data is used, with the intent of lessening the impact of cache misses. This patch adds a manager and interface for matching up client requests for DCA services with devices that offer DCA services. In order to use DCA, a module must do bus writes with the appropriate tag bits set to trigger a cache read for a specific CPU. However, different CPUs and chipsets can require different sets of tag bits, and the methods for determining the correct bits may be simple hardcoding or may be a hardware specific magic incantation. This interface is a way for DCA clients to find the correct tag bits for the targeted CPU without needing to know the specifics.
