[PATCH 0/3] Introduce support for QAT Dynamic Power Management

From: Wojciech Ziemba
Date: Thu Feb 03 2022 - 09:13:29 EST


This patch set consist of following updates:
1. Add misc workqueue for general purpose usage.
2. Move error source related CSRs from 4xxx to the wider GEN4 header
file.
3. Add support for HW QAT Power Management (PM) feature.
This feature is enabled at init time (1) by sending an admin
message to
the firmware, targeting the admin AE, that sets the idle time
before
the device changes state and (2) by unmasking the PM source of
interrupt in ERRMSK2.

The interrupt handler is extended to handle a PM interrupt which
is triggered by HW when a PM transition occurs. In this case,
the
driver responds acknowledging the transaction using the HOST_MSG
mailbox.

crypto: qat - enable power management for QAT GEN4
