rte_compressdev(3)

💅 rte_compressdev — the it girl of DPDK compress devices 🎀

okay so bestie, we're in the Library Functions Manual section and today's main character is rte_compressdev ✨ no cap, this is the struct you want to know if you're doing anything with compression devices in DPDK. she's iconic, she's a little internal, and she's literally defined in a header. let's get into it 💖

---

🌸 NAME 🌸

rte_compressdev — the data structure that's associated with each comp device, periodt. 👑

---

✨ SYNOPSIS ✨

#include <rte_compressdev_internal.h>

🦋 Data Fields 🦋

here's the whole squad that lives inside this struct, in order, no skipping 💅:

compressdev_dequeue_pkt_burst_t dequeue_burst
compressdev_enqueue_pkt_burst_t enqueue_burst
struct rte_compressdev_data * data
struct rte_compressdev_ops * dev_ops
uint64_t feature_flags
struct rte_device * device
__extension__ uint8_t attached: 1

---

💜 Detailed Description 💜

so basically: The data structure associated with each comp device. that's the vibe. one struct per comp device, she holds the whole situation together 🫶

📍 Definition at line 72 of file rte_compressdev_internal.h. write that down bestie, iykyk.

🔥 Field Documentation 🔥

every single field, broken down, because we don't do vague here 💖

⭐ compressdev_dequeue_pkt_burst_t dequeue_burst

Pointer to PMD receive function. that's the function pointer the PMD uses on the receive side, lowkey essential 😭

📍 Definition at line 73 of file rte_compressdev_internal.h.

⭐ compressdev_enqueue_pkt_burst_t enqueue_burst

Pointer to PMD transmit function. same energy, but transmit side — this is the send function pointer fr fr ✨

📍 Definition at line 75 of file rte_compressdev_internal.h.

⭐ struct rte_compressdev_data* data

Pointer to device data. yes, she points at the device's data 🎀

📍 Definition at line 78 of file rte_compressdev_internal.h.

⭐ struct rte_compressdev_ops* dev_ops

Functions exported by PMD. all the ops the PMD hands over live right here 👑

📍 Definition at line 80 of file rte_compressdev_internal.h.

⭐ uint64_t feature_flags

Supported features. this is where the device says what she can do — highkey important 🌈

📍 Definition at line 82 of file rte_compressdev_internal.h.

⭐ struct rte_device* device

Backing device. the actual device sitting behind all this 🦋

📍 Definition at line 84 of file rte_compressdev_internal.h.

⭐ __extension__ uint8_t attached

Flag indicating the device is attached. is she attached or is she not — this 1-bit field knows 💅 (yes, it's __extension__ uint8_t attached: 1, a teeny tiny bitfield, don't come for her)

📍 Definition at line 88 of file rte_compressdev_internal.h.

🍓 one little reminder before you go: these are internal header details, so don't go treating them like a public API promise, bestie — the definition lines are the receipts (lines 72, 73, 75, 78, 80, 82, 84, 88 of rte_compressdev_internal.h).
