2009-09-08ioat: define descriptor control bit-fieldDan Williams
This cleans up a mess of and'ing and or'ing bit definitions, and allows simple assignments from the specified dma_ctrl_flags parameter. Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08ioat: split ioat_dma_probe into core/version-specific routinesDan Williams
Towards the removal of ioatdma_device.version split the initialization path into distinct versions. This conversion: 1/ moves version specific probe code to version specific routines 2/ removes the need for ioat_device 3/ turns off the ioat1 msi quirk if the device is reinitialized for intx Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08ioat: cleanup some long deref chains and 80 column collisionsDan Williams
* reduce device->common. to dma-> in ioat_dma_{probe,remove,selftest} * ioat_lookup_chan_by_index to ioat_chan_by_index * multi-line function definitions * ioat_desc_sw.async_tx to ioat_desc_sw.txd * desc->txd. to tx-> in cleanup routine Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-09-08ioat: convert ioat_probe to pcim/devmDan Williams
The driver currently duplicates much of what these routines offer, so just use the common code. For example ->irq_mode tracks what interrupt mode was initialized, which duplicates the ->msix_enabled and ->msi_enabled handling in pcim_release. This also adds a check to the return value of dma_async_device_register, which can fail.

2009-09-08ioat: move definitions to dma.hDan Williams
Some of these defines may be useful outside of dma.c and the header is private so there are no namespace pollution concerns. Signed-off-by: Maciej Sosnowski <maciej.sosnowski@intel.com> Signed-off-by: Dan Williams <dan.j.williams@intel.com>
2009-07-28ioat: move to drivers/dma/ioat/Dan Williams
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).
