Hi,
This series adds support for user space access to QAT services.
Intel (R) Quick Assist Technology provides acceleration for symmetric,
asymmetric cryptography and compression. Many of these algorithms like
RSA, DSA, Diffie–Hellman, Elliptic Curve are very computational expensive and
accelerating is highly desirable. This patch series implement a new
qat_sym and qat_asym PF_ALG interface that allows access acceleration HW from
user space thorough a QAT library available from 01.org website.
User space applications can use the QAT services through QAT API.
The QAT user space library creates job description requests, and sends
it through qat socket to QAT driver. The driver validates the request,
remaps user virtual memory (for symmetric ciphers) or copies the input
parameters (for public key crypto) and sends it to the acceleration hardware.
The data is then processed and the library is notified when it is ready
by calling select on the socket.
