ice_ddp_send_hunk(9)

📦 version 7.3.1, in nixpkgs unstable

💅 ice_ddp_send_hunk — like, the kernel API manual, bestie ✨

okay so this is ice_ddp_send_hunk(9) and before u panic at the underscores — breathe 🫶 it's a kernel API page, the manual name is literally ice_ddp_send_hunk(9), and we're gonna get through it together. grab a lil snack 🍓

🌸 NAME 🌸

ice_ddp_send_hunk — send one hunk of data to FW 💌

no cap, that's the whole gig. one hunk. to the firmware. slay.

✨ SYNOPSIS ✨

enum ice_ddp_state ice_ddp_send_hunk (struct ice_ddp_send_ctx *ctx ,
struct ice_buf_hdr *hunk );

look at that signature. iconic. two args, both pointers, both important 👑

🎀 ARGUMENTS 🎀

  • ctx — current segment sending context. it's the vibe-keeper, it remembers where we are in the whole sending situation 💖
  • hunk — next hunk to send, size is always ICE_PKG_BUF_SIZE. always. don't come at me with a different size, that's not the move 🙈

🦋 DESCRIPTION 🦋

Send the next hunk of data to FW, retrying if needed. like, it will just keep trying bc it's a main character with ✨persistence✨

Notice: must be called once more with a NULL hunk to finish up; such call will set up the "last" bit of an AQ request. After such call ctx.hdr is cleared, hw is still valid. 🔥

okay this is the part where u have to read carefully bestie — the final NULL call is literally mandatory, it's the "and that's a wrap" moment that sets the "last" bit on the AQ request. not optional. after that call, ctx.hdr is cleared but hw is still valid, so don't go tossing anything out 🧚

⭐ RETURN ⭐

ICE_DDP_PKG_SUCCESS if there were no problems; a sticky err otherwise. 💀

a sticky err — meaning it clings. it does not let go. iykyk 😭
