Subject: [RFC 0/5] Proposal to use netlink for RAS and Telemetry across drm subsystem
Date: Fri, 26 May 2023 21:50:11 +0530	[thread overview]
Message-ID: <20230526162016.428357-1-aravind.iddamsetty@intel.com> (raw)

Our hardware supports RAS(Reliability, Availability, Serviceability) by
exposing a set of error counters which can be used by observability
tools to take corrective actions or repairs. Traditionally there were
being exposed via PMU (for relative counters) and sysfs interface (for
absolute value) in our internal branch. But, due to the limitations in
this approach to use two interfaces and also not able to have an event
based reporting or configurability, an alternative approach to try
netlink was suggested by community for drm subsystem wide UAPI for RAS
and telemetry as discussed in [1]. 

This [1] is the inspiration to this series. It uses the generic
netlink(genl) family subsystem and exposes a set of commands that can
be used by every drm driver, the framework provides a means to have
custom commands too. Each drm driver instance in this example xe driver
instance registers a family and operations to the genl subsystem through
which it enumerates and reports the error counters. An event based
notification is also supported to which userpace can subscribe to and
be notified when any error occurs and read the error counter this avoids
continuous polling on error counter. This can also be extended to
threshold based notification.

this series is on top of https://patchwork.freedesktop.org/series/116181/

Below is an example tool drm_ras which demonstrates the use of the
supported commands. The tool will be sent to ML with the subject
"[RFC i-g-t 0/1] A tool to demonstrate use of netlink sockets to read RAS error counters"

read single error counter:

$ ./drm_ras READ_ONE --device=drm:/dev/dri/card1 --error_id=0x0000000000000005
counter value 0

read all error counters:

$ ./drm_ras READ_ALL --device=drm:/dev/dri/card1
name                                                    config-id               counter
