From c4e8428673425c5b0c7280387c5cb35d60959b97 Mon Sep 17 00:00:00 2001 From: Giovanni Cabiddu Date: Mon, 12 Oct 2020 21:38:20 +0100 Subject: crypto: qat - fix configuration of iov threads The number of AE2FUNC_MAP registers is different in every QAT device (c62x, c3xxx and dh895xcc) although the logic and the register offsets are the same across devices. This patch separates the logic that configures the iov threads in a common function that takes as input the number of AE2FUNC_MAP registers supported by a device. The function is then added to the adf_hw_device_data structure of each device, and called with the appropriate parameters. The configure iov thread logic is added to a new file, adf_gen2_hw_data.c, that is going to contain code that is shared across QAT GEN2 devices.
