STRUCT PCH_GBE_ADAPTER(9)

💅 struct pch_gbe_adapter(9) 💅

okay so bestie, welcome to the Kernel API Manual page for struct pch_gbe_adapter(9) — and yes, it's giving "board's own private little data stash" energy. This is the board specific private data structure, and we're gonna walk through every field like it's a group chat. 🫶

✨ NAME ✨

struct pch_gbe_adapter — board specific private data structure. That's the whole name section; iconic, concise, no notes 💅

🌸 SYNOPSIS 🌸

Here's the struct in all its glory, copied exactly:

       struct pch_gbe_adapter {
           spinlock_t stats_lock;
           spinlock_t ethtool_lock;
           atomic_t irq_sem;
           struct net_device *netdev;
           struct pci_dev *pdev;
           int irq;
           struct net_device *polling_netdev;
           struct napi_struct napi;
           struct pch_gbe_hw hw;
           struct pch_gbe_hw_stats stats;
           struct work_struct reset_task;
           struct mii_if_info mii;
           struct timer_list watchdog_timer;
           u32 wake_up_evt;
           u32 *config_space;
           unsigned long led_status;
           struct pch_gbe_tx_ring *tx_ring;
           struct pch_gbe_rx_ring *rx_ring;
           unsigned long rx_buffer_len;
           unsigned long tx_queue_len;
           bool rx_stop_flag;
           int hwts_tx_en;
           int hwts_rx_en;
           struct pci_dev *ptp_pdev;
           struct pch_gbe_privdata *pdata;
        };

👑 Members 👑

Tiny heads-up: the original gives no member blurb for a few of these fields, so I'm not inventing lore — they still get a bullet because every field deserves its moment. 💖

• stats_lock — spinlock structure for status.
• ethtool_lock — spinlock structure for ethtool.
• irq_sem — semaphore for interrupt.
• netdev — pointer of network device structure.
• pdev — pointer of pci device structure.
• irq — the original has no member blurb for this one; it's in the synopsis, and I'm leaving it exactly as mysterious as it came. 😌
• polling_netdev — pointer of polling network device structure.
• napi — NAPI structure.
• hw — the original says "Pointer of hardware structure" and I'm just relaying the message 💅
• stats — hardware status.
• reset_task — reset task.
• mii — MII information structure.
• watchdog_timer — watchdog timer list.
• wake_up_evt — wake up event.
• config_space — configuration space.
• led_status — LED status.
• tx_ring — pointer of Tx descriptor ring structure.
• rx_ring — pointer of Rx descriptor ring structure.
• rx_buffer_len — receive buffer length.
• tx_queue_len — transmit queue length.
• rx_stop_flag — no member blurb in the original for this one; still in the struct, still valid, no made-up facts. 😌
• hwts_tx_en — no member blurb in the original for this one; it's in the synopsis and I will not invent a meaning. 🫶
• hwts_rx_en — no member blurb in the original for this one either; same energy, same rule. 💖
• ptp_pdev — no member blurb in the original; it's literally just chilling in the struct. 🦋
• pdata — no member blurb in the original; present in the synopsis, mysterious in the Members list, periodt. 💅
