🌸 NAME 🌸

rte_pmu_event_group — like, the whole entire struct, bestie 💅

So this page is from the Library Functions Manual (that's the manual name, iykyk), and it's all about one lil struct that holds a group of events. Let's get into it 🫶

✨ SYNOPSIS ✨

First things first, you gotta pull in the header:

• TAILQ_ENTRY (rte_pmu_event_group) next — the list entry, slaying in TAILQ form ✨

🎀 Data Fields

• struct perf_event_mmap_page * mmap_pages [RTE_MAX_NUM_GROUP_EVENTS] — an array of user pages 👑
• int fds [RTE_MAX_NUM_GROUP_EVENTS] — an array of event descriptors 🍓
• bool enabled — true if the group was enabled on a particular lcore, no cap 💀
