When first created the ioat driver was the only inhabitant of
drivers/dma/. Now, it is the only multi-file (more than a .c and a .h)
driver in the directory. Moving it to an ioat/ subdirectory allows the
naming convention to be cleaned up, and allows for future splitting of
the source files by hardware version (v1, v2, and v3).

I/OAT: I/OAT version 3.0 support2008-07-23T00:30:57+00:00Maciej Sosnowskimaciej.sosnowski@intel.com2008-07-23T00:30:57+00:00urn:sha1:7f1b358a236ee9c19657a619ac6f2dcabcaa0924
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

I/OAT: Add support for version 2 of ioatdma device2007-11-15T02:45:41+00:00Shannon Nelsonshannon.nelson@intel.com2007-11-15T00:59:51+00:00urn:sha1:7bb67c14fd3778504fb77da30ce11582336dfced
Add support for version 2 of the ioatdma device. This device handles
the descriptor chain and DCA services slightly differently:
- Instead of moving the dma descriptors between a busy and an idle chain,
this new version uses a single circular chain so that we don't have
rewrite the next_descriptor pointers as we add new requests, and the
device doesn't need to re-read the last descriptor.
- The new device has the DCA tags defined internally instead of needing
them defined statically.

I/OAT: Split PCI startup from DMA handling code2007-10-16T16:43:09+00:00Shannon Nelsonshannon.nelson@intel.com2007-10-16T08:27:39+00:00urn:sha1:8ab89567da0cea9bae2c1b5dad47b51c424479e4
Split the general PCI startup from the DMA handling code in order to
prepare for adding support for DCA services and future versions of the
ioatdma device.
