[4/4] dca: fixup initialization dependency

2008-11-10T23:01:03Z

Mark dca_init as a subsys_initcall since it needs to be ready to go before dependent drivers start registering themselves. Cc: Reported-and-tested-by: Mark Rustad Acked-by: Maciej Sosnowski Signed-off-by: Dan Williams Signed-off-by: David S. Miller

device create: misc: convert device_create_drvdata to device_create

2008-10-16T16:24:43Z

Now that device_create() has been audited, rename things back to the original call to be sane. Signed-off-by: Greg Kroah-Hartman

I/OAT: I/OAT version 3.0 support

2008-07-23T00:30:57Z

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 Signed-off-by: Dan Williams

device create: dca: convert device_create to device_create_drvdata

2008-07-22T04:54:41Z

device_create() is race-prone, so use the race-free device_create_drvdata() instead as device_create() is going away. Signed-off-by: Greg Kroah-Hartman

I/OAT: Add DCA services

DCA: Add Direct Cache Access driver

2007-10-16T16:43:09Z

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.
