Description: (RO) Read returns the number of requests sent to the FW and the number of responses

received from the FW for each Acceleration Engine

|

Description: (RW) Read returns value of the Heartbeat update period.
|
||
Write to the file changes this period value.
|
||
|
||
This period should reflect planned polling interval of device
|
||
health status. High frequency Heartbeat monitoring wastes CPU cycles
|
||
but minimizes the customer’s system downtime. Also, if there are
|
||
large service requests that take some time to complete, high frequency
|
||
Heartbeat monitoring could result in false reports of unresponsiveness
|
||
and in those cases, period needs to be increased.
|
||
|
||
This parameter is effective only for c3xxx, c62x, dh895xcc devices.
|
||
4xxx has this value internally fixed to 200ms.
|
||
|
||
Default value is set to 500. Minimal allowed value is 200.
|
||
All values are expressed in milliseconds.

Description: (RO) Read returns the device health status.
|
||
|
||
Returns 0 when device is healthy or -1 when is unresponsive
|

or the query failed to send.
|
||
|
||
The driver does not monitor for Heartbeat. It is left for a user
|
||
to poll the status periodically.
