Description:
6+
The `features-<PCI BDF>/` directory represents the "features"
7+
capability exposed by Intel PMT (Platform Monitoring Technology)
8+
for the given PCI device.
9+
10+
Each directory corresponds to a PMT feature and contains
11+
attributes describing the available telemetry, monitoring, or
12+
control functionalities.

Common Files (Present in all feature directories):
28+
29+
caps
30+
- Read-only
31+
- Lists available capabilities for this feature.
32+
33+
guids
34+
- Read-only
35+
- Lists GUIDs associated with this feature.
36+
37+
Additional Attributes (Conditional Presence):
38+
39+
max_command_size
40+
- Read-only
41+
- Present if the feature supports out-of-band MCTP access.
42+
- Maximum supported MCTP command size for out-of-band PMT access (bytes).
43+
44+
max_stream_size
45+
- Read-only
46+
- Present if the feature supports out-of-band MCTP access.
47+
- Maximum supported MCTP stream size (bytes).
48+
49+
min_watcher_period_ms
50+
- Read-only
51+
- Present if the feature supports the watcher API.
52+
The watcher API provides a writable control interface that allows user
53+
configuration of monitoring behavior, such as setting the sampling or
54+
reporting interval.
55+
- Minimum supported time period for the watcher interface (milliseconds).
56+
57+
num_rmids
58+
- Read-only
59+
- Present if the feature supports RMID (Resource Monitoring ID) telemetry.
60+
RMIDs are identifiers used by hardware to track and report resource usage,
61+
such as memory bandwidth or energy consumption, on a per-logical-entity
62+
basis (e.g., per core, thread, or process group).
63+
- Maximum number of RMIDs tracked simultaneously.
64+
65+
Example:
66+
For a device with PCI BDF `0000:00:03.1`, the directory tree could look like:

Notes:
107+
- Some attributes are only present if the corresponding feature supports
108+
the capability (e.g., `max_command_size` for MCTP-capable features).
109+
- Features supporting RMIDs include `num_rmids`.
110+
- Features supporting the watcher API include `min_watcher_period_ms`.
111+
- The `caps` file provides additional information about the functionality
112+
of the feature.
