dmaengine: idxd: Init and probe for Intel data accelerators The idxd driver introduces the Intel Data Stream Accelerator [1] that will be available on future Intel Xeon CPUs. One of the kernel access point for the driver is through the dmaengine subsystem. It will initially provide the DMA copy service to the kernel. Some of the main functionality introduced with this accelerator are: shared virtual memory (SVM) support, and descriptor submission using Intel CPU instructions movdir64b and enqcmds. There will be additional accelerator devices that share the same driver with variations to capabilities. This commit introduces the probe and initialization component of the driver.

dmaengine: idxd: add char driver to expose submission portal to userland Create a char device region that will allow acquisition of user portals in order to allow applications to submit DMA operations. A char device will be created per work queue that gets exposed. The workqueue type "user" is used to mark a work queue for user char device. For example if the workqueue 0 of DSA device 0 is marked for char device, then a device node of /dev/dsa/wq0.0 will be created.
