Hi Dan,
I have 8 NVDIMMs in my system and I have them configured in various ways.
When I run 'ndctl list', I get a nice simple summary of all of my devices.
What's missing though is the "chardev" information for my dax devices.
I do see that I can get it, and more, if I run 'ndctl list -X' but that
only gives me information about dax namespaces. I can also get it if I run
'daxctl list', but without any other useful information. You can see all
the sample output below.
Is there a reason we can't have "chardev" in the output of 'ndctl list'
so that all the basic information is in one place? I'm happy to do a
patch but since this has changed a bit (and I think the information
used to be there?), I thought I'd ask if there's a reason you omitted it.
Thanks,
