Description:
|
|
The telem<x> directory contains files describing an instance of
|
|
a PMT telemetry device that exposes hardware telemetry. Each
|
|
telem<x> directory has an associated telem file. This file
|
|
may be opened and mapped or read to access the telemetry space
|
|
of the device. The register layout of the telemetry space is
|
|
determined from an XML file that matches the PCI device id and
|
|
GUID for the device.

Description:
|
|
The crashlog<x> directory contains files for configuring an
|
|
instance of a PMT crashlog device that can perform crash data
|
|
recording. Each crashlog<x> device has an associated crashlog
|
|
file. This file can be opened and mapped or read to access the
|
|
resulting crashlog buffer. The register layout for the buffer
|
|
can be determined from an XML file of specified GUID for the
|
|
parent device.

|
(RW) Boolean value controlling the triggering of the crashlog
|
|
device node. When read it provides data on if the crashlog has
|
|
been triggered. When written to it can be used to either clear
|
|
the current trigger by writing false, or to trigger a new
|
|
event if the trigger is not currently set.
