ice_devlink_nvm_snapshot(9)

🎀 NAME 🎀

ice_devlink_nvm_snapshot — capture a snapshot of the NVM flash contents. This is the Kernel API Manual page for ice_devlink_nvm_snapshot(9), and she is literally here to grab flash contents for you, bestie. 💖

✨ SYNOPSIS ✨

okay so here’s the exact signature, no edits, no cap:

int ice_devlink_nvm_snapshot (struct devlink *devlink , const struct
       devlink_region_ops *ops , struct netlink_ext_ack *extack , u8 **data );

---

💅 ARGUMENTS 💅

• devlink — the devlink instance. Main character pointer energy.
• ops — the devlink region to snapshot. This is the region we’re serving.
• extack — extended ACK response structure.
• data — on exit points to snapshot data buffer. Yes, it’s the output bestie.

🦋 DESCRIPTION 🦋

This function is called in response to a DEVLINK_CMD_REGION_NEW for either the nvm-flash or shadow-ram region.

It captures a snapshot of the NVM or Shadow RAM flash contents. This snapshot can then later be viewed via the DEVLINK_CMD_REGION_READ netlink interface. Obsessed with the whole pipeline. 🌈

It returns zero on success, and updates the data pointer. Returns a non-zero error code on failure. So: success = zero, failure = non-zero. That’s the whole vibe check. 💀
