DEVLINK-RESOURCE(8)

💖 DEVLINK-RESOURCE 💖

okay bestie, welcome to devlink-resource — the part of the devlink world that's all about device resource configuration. it's giving "let me peek at your resources and also maybe resize them" energy, and honestly? iconic. 🎀

this one lives in the Linux manual, section 8, and it's your go-to for showing and setting devlink device resources. no cap.

OPTIONS := { -v[erbose] }

devlink resource show [ DEV[/PORT_INDEX] | scope { dev | port } ]

🌸 DESCRIPTION 🌸

🦋 devlink resource show — display devlink device resources

DEV — tells it which devlink device to show. and if you just… don't say anything? it lists all the devices. main character behavior tbh.

format is:

BUS_NAME/BUS_ADDRESS

PORT_INDEX — picks the port to show resources for. when you give it one, you only get the port-level resources for that port. no extras, no noise.

format is:

BUS_NAME/BUS_ADDRESS/PORT_INDEX

scope { dev | port }

filter your resources by scope, bestie:

• dev shows only device-level resources.
• port shows only port-level resources.
• omit it and you get resources of both scopes. everything. the whole buffet. ✨

💜 devlink resource set — sets resource size of specific resource

DEV — which devlink device you're messing with.

path RESOURCE_PATH

the resource's path. that's it, that's the vibe.

size RESOURCE_SIZE

the new resource's size. glow-up incoming. 🔥
