STRUCT VPORT_UPCALL_STATS_PERCPU(9)

💖 struct vport_upcall_stats_percpu — Kernel API Manual ✨

okay so bestie, welcome to the manual page for struct vport_upcall_stats_percpu — it's the per-cpu packet upcall statistics for a given vport. yes, that's a lot of words, but it's literally just a little bookkeeping struct that keeps track of how your upcalls went. we stan a tidy data structure 🎀

🌸 SYNOPSIS 🌸

struct vport_upcall_stats_percpu {
    struct u64_stats_sync syncp;
    u64_stats_t n_success;
    u64_stats_t n_fail;
 };

that's the whole thing, bestie. three members, no drama. 🦋

✨ Members ✨

💅 the fields, one by one

• syncp — the synchronization point for the 64bit counters. it's giving "line up, besties, no chaotic reads in this house" 🔥
• n_success — the number of packets whose upcall to userspace succeeded. slay, the packets made it 🎉💖
• n_fail — the number of packets whose upcall to userspace failed. it happens, we don't judge, we just count it 😭💀

👑 SEE ALSO 👑

• Kernel file ./net/openvswitch/vport.h
• struct vport_portids(9)
• struct vport(9)
• struct vport_parms(9)
• struct vport_ops(9)
• vport_priv(9)
• vport_from_priv(9)

go read those too, iykyk — they're all hanging out in the same kernel file and they're lowkey iconic 🌈⭐

ngl, n_success and n_fail are 64bit counters, so please respect the syncp — it's there for a reason, bestie 🙈

okay that's the whole page, mwah 💋 this came from ./net/openvswitch, dated October 2026, and it's the struct vport...stats_percpu(9) page — catch you in the next one, bestie 🫶🧚💜
