STRUCT DPDMAI_RX_QUEUE_CFG(9)

💖 NAME 💖

ok so this is struct dpdmai_rx_queue_cfg — literally the DPDMAI RX queue configuration, bestie. that's the whole vibe. it's a Kernel API Manual page (section 9, iykyk), and it's here to explain the little struct you use to set up a receive queue. slay.

✨ SYNOPSIS ✨

here's the struct in all its glory, copy it exactly, don't @ me:

struct dpdmai_rx_queue_cfg {
    struct dpdmai_dest_cfg dest_cfg;
    u32 options;
    u64 user_ctx;
 };

three members. that's it. that's the whole struct. lowkey iconic in its simplicity 💅

🎀 Members 🎀

okay bestie, let's go member by member, no skipping:

• dest_cfg — the queue destination parameters 🛸 and here's the tea: this one is only valid if 'DPDMAI_QUEUE_OPT_DEST' is contained in 'options'. so if you didn't set that flag, this field is just sitting there doing nothing. main character energy with no screentime, honestly.
• options — the flags that represent the suggested modifications to the queue ✨ use any combination of the 'DPDMAI_QUEUE_OPT_<X>' flags. mix and match, it's giving build-your-own-adventure.
• user_ctx — a user context value that gets provided in the frame descriptor of each dequeued frame 🦋 and here's the catch: it's valid only if 'DPDMAI_QUEUE_OPT_USER_CTX' is contained in 'options'. same deal as dest_cfg, no flag = no validity. fr fr.

⚠️ heads up bestie: both dest_cfg and user_ctx are flag-gated. forgetting the matching options flag means the field doesn't count. vibe check your flags before you ship, okay? 😭

👑 SEE ALSO 👑

go look at these, they're literally the friend group 🫶:

• Kernel file ./drivers/dma/fsl-dpaa2-qdma/dpdmai.h — the actual home of all this
• struct dpdmai_cfg(9)
• struct dpdmai_attr(9)
• enum dpdmai_dest(9)
• struct dpdmai_dest_cfg(9)
• struct dpdmai_rx_queue_attr(9)

and that's the page, bestie! 🧚 this whole thing lives in ./drivers/dma/fsl-dpaa2-qdma, dated October 2026, and it's filed under struct dpdmai_rx_queue_cfg(9). go forth and configure your RX queues, you absolute legend 💜🌸
