module/idxd: accel framework plug-in for idxd Docs, RPC, unit tests, etc., will follow. Notes: * The current implementation will only work with VFIO. * The current implementation supports only the existing accel framework API. The API will be expanded for DSA exclusive features in a subsequent patch. * SW is required to manage flow control, to not over-run the work queues. This is provided in the accel plug-in module. The upper layers use public API to manage this. * As we need to support any number of channels (we can't limit ourselves to the number of work queues) we need to dynamically size/resize our per channel descriptor rings based on the number of current channels. This is done from upper layers via public API into the lib. * As channels are created, the total number of work queue slots is divided across the channels evenly. Same thing when they are destroyed, remaining channels will see the ring sizes increase. This is done from upper layers via public API into the lib.

modules/accel_dsa: update IDXD references to DSA where it makes sense IDXD has always been used everywhere but technically it stands for the driver, not the HW (Intel Data Streaming Accelerator Driver) where the X comes from "Streaming Accelerator" somehow. Anyway, the underlying hardware is just DSA. It doesn't matter much now but upcoming patches will add support for a new HW accelerator called the Intel In-Memory Analytics Accelerator which we'll call IAA and it will use the same (mostly) device driver (IDXD) as DSA. So, calling the HW what it is will lessen confusion when adding IAA support. This patch just does renaming for the accel_fw module and associated files (RPC, etc).

modules/accel_dsa: update IDXD references to DSA where it makes sense IDXD has always been used everywhere but technically it stands for the driver, not the HW (Intel Data Streaming Accelerator Driver) where the X comes from "Streaming Accelerator" somehow. Anyway, the underlying hardware is just DSA. It doesn't matter much now but upcoming patches will add support for a new HW accelerator called the Intel In-Memory Analytics Accelerator which we'll call IAA and it will use the same (mostly) device driver (IDXD) as DSA. So, calling the HW what it is will lessen confusion when adding IAA support. This patch just does renaming for the accel_fw module and associated files (RPC, etc).

lib/jsonrpc: Add a new API to send response for writing bool result. There are many duplicated codes about sending response for writing bool result. That we need a function to do this. Then we can reduce many codes.

module/idxd: accel framework plug-in for idxd Docs, RPC, unit tests, etc., will follow. Notes: * The current implementation will only work with VFIO. * The current implementation supports only the existing accel framework API. The API will be expanded for DSA exclusive features in a subsequent patch. * SW is required to manage flow control, to not over-run the work queues. This is provided in the accel plug-in module. The upper layers use public API to manage this. * As we need to support any number of channels (we can't limit ourselves to the number of work queues) we need to dynamically size/resize our per channel descriptor rings based on the number of current channels. This is done from upper layers via public API into the lib. * As channels are created, the total number of work queue slots is divided across the channels evenly. Same thing when they are destroyed, remaining channels will see the ring sizes increase. This is done from upper layers via public API into the lib.
