STRUCT IWL_RXQ_SYNC_CMD(9)

💅 struct iwl_rxq_sync_cmd(9) 💅

okay bestie, so this is a page straight outta the Kernel API Manual — yes, the manual is literally called Kernel API Manual, and this struct is the whole main character of it. it's called struct iwl_rxq_sync_cmd, and ngl the vibes are immaculate: it's the RXQ notification trigger. that's the NAME section, we ate that. ✨

🦋 SYNOPSIS 🦋

struct iwl_rxq_sync_cmd {
    __le32 flags;
    __le32 rxq_mask;
    __le32 count;
    u8 payload[];
 };

like, look at her. four fields. one flexible array member at the end doing the absolute most. she's giving lowkey iconic C. 🎀

🌸 Members 🌸

• flags — the flags of the notification, bestie. specifically: bit 0:3 are the sender queue. yes, exactly like that, 0:3. iykyk. 💅
• rxq_mask — the rx queues you wanna send this notification on. it's a mask, so like, mask behavior, you know the drill. 🫶
• count — number of bytes in payload. and listen: it should be DWORD aligned. don't do her dirty with a misaligned count. 😭
• payload — the actual data you're sending to the rx queues. this is the u8 payload[] situation, the flexible array, the part that carries the whole personality. it's giving main character energy fr fr. 🔥

yes that's all of them, no i did not skip any, we don't do that here. go read them all, bestie, it's a whole saga. 📚✨

real talk: the count needs to be DWORD aligned. that's not a vibe suggestion, that's in the docs. consider yourself warned. 🙈

and that's the page, bestie! 🎀 it came from ./drivers/net/wireless/intel/i... and it's stamped October 2026 — a page so fresh it's basically a time traveler. go forth and trigger those RXQ notifications. slay. 👑💖
