ice_devlink...d_empr_start(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

okay so bestie, this is the <rainbow>ice_devlink_reload_empr_start(9)</rainbow> manual page β€” one of those lil kernel API gems from the Kernel API Manual, and honestly it's serving "small function, big responsibility" energy. let's get into it ✨


🌸 NAME 🌸

ice_devlink_reload_empr_start β€” start that EMP reset so your new firmware can actually, you know, activate πŸ’–

✨ SYNOPSIS ✨

int ice_devlink_reload_empr_start (struct ice_pf *pf , struct
       netlink_ext_ack *extack );

lowkey the whole signature, exactly as it lives, no cap 🫢

πŸŽ€ ARGUMENTS πŸŽ€

  • pf β€” pointer to the pf instance. yep, it's the pf. it's giving "the main character" of this whole call πŸ’…
  • extack β€” the netlink extended ACK structure. think of it as the receipts holder for any error gossip that needs to travel back πŸ“¨

πŸ¦‹ DESCRIPTION πŸ¦‹

so basically this is the function that lets the user activate new Embedded Management Processor firmware by issuing a device specific EMP reset 😭πŸ”₯ iconic.

it gets called in response to a DEVLINK_CMD_RELOAD with the DEVLINK_RELOAD_ACTION_FW_ACTIVATE β€” and if you're like "wait, which reload action again?" it's DEVLINK_RELOAD_ACTION_FW_ACTIVATE. periodt.

πŸ’€ heads up bestie β€” teardown and rebuild of the driver state happens automatically, as part of an interrupt and watchdog task. not by you, not by me, it just happens. why? because all physical functions on the device must be able to reset when an EMP reset occurs from any source. that's the rule, that's the vibe β€” it's a group reset sitch, everyone's involved 🌈

and that's the page, bestie πŸ“ it comes to you from ./drivers/net/ethernet/intel/i... (the source line, doing its lil truncated thing, we love that for it πŸ™ˆ), dated October 2026, and signed off as ice_devlink...d_empr_start(9). go forth and activate that firmware πŸ§šπŸ’œ
