* dca: redesign locks to fix deadlocksMaciej Sosnowski2009-02-021-18/+33
| | | | | | | | | | | Change spin_locks to irqsave to prevent dead-locks. Protect adding and deleting to/from dca_providers list. Drop the lock during dca_sysfs_add_req() and dca_sysfs_remove_req() calls as they might sleep (use GFP_KERNEL allocation).

| | | | | | | | | | | | | | | | | | | | | | | | This patch adds to ioatdma and dca modules support for Intel I/OAT DMA engine ver.3 (aka CB3 device).

* DCA: Add Direct Cache Access driverShannon Nelson2007-10-164-0/+301
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.
