📦 version 7.3.1, in nixpkgs unstable

💖 ice_alloc_res_cntr — allocating resource counter 💖

okay so this is a page from the Kernel API Manual, bestie, and it's all about one tiny little function that grabs you a resource counter. yes it's niche. yes it's iconic. let's get into it 🫶

✨ NAME ✨

ice_alloc_res_cntr — allocating resource counter. that's the whole vibe. it allocates. a counter. for resources. periodt 💅

🌸 SYNOPSIS 🌸

int ice_alloc_res_cntr (struct ice_hw *hw , u8 type , u8 alloc_shared ,
u16 num_items , u16 *counter_id );

so she takes five things and gives you back an int — classic. the return value is the main character here, everything else is supporting cast 🎀

🦋 DESCRIPTION 🦋

okay there's no separate DESCRIPTION section on this page (I know, I know, a little robbed) but like — the NAME and ARGUMENTS are literally carrying the whole explanation, so scroll down and meet the cast 💜

👑 ARGUMENTS 👑

  • hw — pointer to the hardware structure. this is your little handle on the actual NIC hardware, she's the plug 🔌
  • type — type of resource. literally just: which flavor of resource are we counting rn 🍓
  • alloc_shared — if set it is shared else dedicated. so like, set = shared (we're sharing, we're communal, we're a group chat), unset = dedicated (mine, only mine, do not perceive) 🙈
  • num_items — number of entries requested for FD resource type. this is the "how many do you want" number, but heads up — it's specifically for the FD resource type, so don't go applying it to everything, iykyk ✨
  • counter_id — counter index returned by AQ call. this is the output, the lil receipt, the ID that comes back to you after the AQ call does its thing 🎀

🌈 SEE ALSO 🌈

buckle up bestie, this is the entire extended friend group — the whole ice_switch.c squad, no cap. every single one of these is real and every single one made the list 😭🔥

also, and don't forget this one, the actual kernel file she lives in:

./drivers/net/ethernet/intel/ice/ice_switch.c

like, that's the address, that's where she at 💅

lowkey a reminder bestie: the source path above is ./drivers/net/ethernet/intel/ice and the date on this thing is October 2026 — so if you're reading this in the future, hi, love you, hope the counters are behaving 🫶✨

and that's the page!! go forth and allocate responsibly, mwah 💖🎀🦋
