crypto: qat - fix crypto capability detection for 4xxx

2023-08-25T10:46:55Z

When extending the capability detection logic for 4xxx devices the SMx algorithms were accidentally missed. Enable these SMx capabilities by default for QAT GEN4 devices. Check for device variants where the SMx algorithms are explicitly disabled by the GEN4 hardware. This is indicated in fusectl1 register. Mask out SM3 and SM4 based on a bit specific to those algorithms. Mask out SM2 if the PKE slice is not present.

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23Z

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

crypto: qat - add heartbeat counters check

2023-07-20T10:16:23Z

A firmware update for QAT GEN2 changed the format of a data structure used to report the heartbeat counters. To support all firmware versions, extend the heartbeat logic with an algorithm that detects the number of counters returned by firmware. The algorithm detects the number of counters to be used (and size of the corresponding data structure) by the comparison the expected size of the data in memory, with the data which was written by the firmware. Firmware detection is done one time during the first read of heartbeat debugfs file to avoid increasing the time needed to load the module.

crypto: qat - add heartbeat feature

2023-07-20T10:16:23Z

Under some circumstances, firmware in the QAT devices could become unresponsive. The Heartbeat feature provides a mechanism to detect unresponsive devices. The QAT FW periodically writes to memory a set of counters that allow to detect the liveness of a device. This patch adds logic to enable the reporting of those counters, analyze them and report if a device is alive or not. In particular this adds (1) heartbeat enabling, reading and detection logic (2) reporting of heartbeat status and configuration via debugfs (3) documentation for the newly created sysfs entries (4) configuration of FW settings related to heartbeat, e.g. tick period (5) logic to convert time in ms (provided by the user) to clock ticks This patch introduces a new folder in debugfs called heartbeat with the following attributes: - status - queries_sent - queries_failed - config All attributes except config are reading only. In particular: - `status` file returns 0 when device is operational and -1 otherwise. - `queries_sent` returns the total number of heartbeat queries sent. - `queries_failed` returns the total number of heartbeat queries failed. - `config` allows to adjust the frequency at which the firmware writes counters to memory. This period is given in milliseconds and it is fixed for GEN4 devices. Signed-off-by: Damian Muszynski Reviewed-by: Giovanni Cabiddu Reviewed-by: Andy Shevchenko Signed-off-by: Herbert Xu
