Do you mean that we will register resources per port, but not show with
new devlink port resource show.
Instead, the current devlink resource show dev command will also display
the ports of that device?
For example:
$ devlink resource show pci/0000:03:00.0
pci/0000:03:00.0:
name local_max_SFs size 40 unit entry
pci/0000:03:00.0/196608:
name max_SFs size 20 unit entry
pci/0000:03:00.0/196609:
name max_SFs size 20 unit entry
Or should we keep the current behavior where devlink resource show dev
displays only device-level resources, and only the full dump shows both
devices and their ports?
For example:
$ devlink resource show
pci/0000:03:00.0:
name local_max_SFs size 40 unit entry
pci/0000:03:00.0/196608:
name max_SFs size 20 unit entry
pci/0000:03:00.0/196609:
name max_SFs size 20 unit entry
pci/0000:03:00.1:
name local_max_SFs size 40 unit entry
pci/0000:03:00.1/196608:
name max_SFs size 20 unit entry
pci/0000:03:00.1/196609:
name max_SFs size 20 unit entry
Want to confirm which behavior you meant.
No strong preference on the CLI. For the kernel I think specifying
the device should not exclude the port resources. Whether port
resources are shown or not should be entirely up to the mask attribute.
Thinking about this some more after my last reply to Jiri I think we
should add that mask attribute to let user decide whether they want
only the device resources, port resources or both. This will retain
the exact functionality of the series.
On the CLI "devlink resource show" should show all resources in the
system IMO. How we define the CLI arguments to scope things down I don't
have a strong opinion on.
So for the dump of all resources it is clear. But I want to make sure I
understood the scope/mask part:
For the dump-it command:
devlink resource show
pci/0000:03:00.0:
<resource>
pci/0000:03:00.0/196608:
<port-resource>
pci/0000:03:00.0/196609:
<port-resource>
pci/0000:03:00.1:
<resource>
pci/0000:03:00.1/262144:
<port-resource>
devlink resource show scope port
pci/0000:03:00.0/196608:
<port-resource>
pci/0000:03:00.0/196609:
<port-resource>
pci/0000:03:00.1/262144:
<port-resource>
devlink resource show scope dev
pci/0000:03:00.0:
<resource>
pci/0000:03:00.1:
<resource>
For the do-it command:
devlink resource show pci/0000:03:00.0
pci/0000:03:00.0:
<resource>
pci/0000:03:00.0/196608:
<port-resource>
pci/0000:03:00.0/196609:
<port-resource>
devlink resource show pci/0000:03:00.0 scope port
pci/0000:03:00.0/196608:
<port-resource>
pci/0000:03:00.0/196609:
<port-resource>
devlink resource show pci/0000:03:00.0 scope dev
pci/0000:03:00.0:
<resource>
The way to get the dev or port scope will be by bitmask in the netlink
message of the dump/doit command.
Thank you
