Define a new netlink event 'error-event' and a new multicast group
'error-notify' in drm_ras. Each event contains device name, node and
error information to identify the error triggering the event.
Add drm_ras_nl_error_event() to trigger an event from the driver.
Wire this support to xe drm_ras to notify userspace whenever a GT or
SoC error occurs in PVC.
$ sudo ./tools/net/ynl/pyynl/cli.py --family drm_ras --output-json \
--subscribe error-notify
{
"name": "error-event",
"msg": {
"device-name": "0000:03:00.0",
"node-id": 1,
"node-name": "uncorrectable-errors",
"error-id": 1,
"error-name": "core-compute",
"error-value": 1
}
}
