This tool is to demonstrate the use of netlink sockets to read RAS error
counters, which is being proposed via series
"[RFC v2 0/5] Proposal to use netlink for RAS and Telemetry across drm subsystem".

The tool supports the following commands:
READ_ONE, READ_ALL, WAIT_ON_EVENT, LIST_ERRORS

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

From: Aravind Iddamsetty @ 2023-08-25 12:02 UTC (permalink / raw)
  To: intel-xe; +Cc: igt-dev

This tool demonstrates the use of netlink sockets to query and read the
error counters on a hardware. It provides following commands LIST_ERRORS,
READ_ONE, READ_ALL to read counters and WAIT_ON_EVENT to wait for
occurrence on a particular event, presently hardcoded to wait on
occurrence of correctable error event and read a error counter.

v2: update uapi header.
