Currently a device does not belong to any of the numa nodes
(dev->numa_node is NUMA_NO_NODE) when the FW does not provide
the node id and the device has not no parent device.

According to discussion in [1]:
Even if a device's numa node is not set by fw, the device
really does belong to a node.

This patch sets the device node to node 0 in device_add() if
the fw has not specified the node id and it either has no
parent device, or the parent device also does not have a valid
node id.

There may be explicit handling out there relying on NUMA_NO_NODE,
like in nvme_probe().

dev_err() will show you the exact device properly, instead of having to
rely on dev_name().

And what is a user to do if this message happens?  How do they fix this?
If they can not, what good is this error message?

Sure. May I ask why "? :" is not appropriate here?

If user know about their system's topology well enough and node 0
is not the nearest node to the device, maybe user can readjust that by
writing the nearest node to /sys/class/pci_bus/XXXX/device/numa_node,
if not, then maybe user need to contact the vendor for info or updates.

Maybe print error message as below:

dev_err(dev, FW_BUG "has invalid NUMA node(%d). Readjust it by writing to sysfs numa_node or contact your vendor for updates.\n",
	dev_to_node(dev));

Because it is a pain to read, just spell it out and make it obvious what
is happening.  You write code for developers first, and the compiler
second, and in this case, either way is identical to the compiler.

FW_BUG?

Anyway, if you make this change, how many machines start reporting this
error?  You should also say something like "default node of 0 now
selected" or something like that, right?

The sysfs numa_node writing interface does print FW_BUG error.
Maybe it is a way of telling the user to contact the vendors, which
pushing the vendors to update the FW.

If FW_BUG is too much, there is FW_WARN or FW_INFO.

But is this always going to be caused by a firmware bug?  If so, ok, if
not, and it's a driver/bus kernel issue, we should not say this.

Ok, Make sense. Will not add the FW_BUG printing.

Any machines with more than one numa node will start reporting this error.

1) many virtual deivces maybe do not set the node id before calling
   device_register(), such as vfio, tun, etc.

2) struct cpu has a dev, but does not set the dev' node according to
   cpu_to_node().

3) Many platform Device also do not have a node id provided by FW.


Below is my system with 4 nodes:

Then this patch is not ok, as you are flooding the kernel log saying the
system is "broken" when this is just what it always has been like.  How
is anyone going to "fix" things?

You can adjust the default node to 0 as isn't that what always has
happened, but you can not claim it is a "error" that this is happening
because it is not an error, it's just the default operation.

cpu->node_id does not seem to be used, maybe we can fix the cpu device:

You are right, will remove the error log.

I have no idea what you are trying to do here, it feels like you are
flailing around trying to set something that almost no bios/firmware
sets or cares about.

If setting the proper node is a requirement, make sure your firmware
does this and then all should be fine.  Otherwise just use the default
node like what happens today, right?

thanks,

The above isn't related to my problem really.

It just that there may be three fields that can indicate
the node id of a cpu:
per_cpu(numa_node), cpu->node_id and cpu->dev.numa_node

The per_cpu(numa_node) may be used for the fast path, and
cpu->node_id does not seems to be used, so it can be removed
when cpu->dev.numa_node is there.

Anyway, this is different problem here, maybe a separate patch
to "fix" it or clean it up if the above makes sense to you.

Sorry for the confusion.

Yes
