STRUCT ATH_INTERRUPT_STATS(9)

💅 NAME 💅

okay bestie, so struct ath_interrupt_stats — from the Kernel API Manual, section 9, main character energy — is literally the struct that holds all the stats about interrupts ✨ like every counter your wifi driver is keeping an eye on, all chillin' in one place 🎀

🦋 SYNOPSIS 🦋

struct ath_interrupt_stats {
    u32 total;
    u32 rxok;
    u32 rxlp;
    u32 rxhp;
    u32 rxeol;
    u32 rxorn;
    u32 txok;
    u32 txeol;
    u32 txurn;
    u32 mib;
    u32 rxphyerr;
    u32 rx_keycache_miss;
    u32 swba;
    u32 bmiss;
    u32 bnr;
    u32 cst;
    u32 gtt;
    u32 tim;
    u32 cabend;
    u32 dtimsync;
    u32 dtim;
    u32 bb_watchdog;
    u32 tsfoor;
    u32 mci;
    u32 gen_timer;
    u32 sync_cause_all;
    u32 sync_rtc_irq;
    u32 sync_mac_irq;
    u32 eeprom_illegal_access;
    u32 apb_timeout;
    u32 pci_mode_conflict;
    u32 host1_fatal;
    u32 host1_perr;
    u32 trcv_fifo_perr;
    u32 radm_cpl_ep;
    u32 radm_cpl_dllp_abort;
    u32 radm_cpl_tlp_abort;
    u32 radm_cpl_ecrc_err;
    u32 radm_cpl_timeout;
    u32 local_timeout;
    u32 pm_access;
    u32 mac_awake;
    u32 mac_asleep;
    u32 mac_sleep_access;
};

look at all those u32s, it's giving "I alphabetized my playlist and then gave up" 💀 but no, it's fine, it's iconic, iykyk 🌸

🧚 Members 🧚

breaking it down one field at a time, bestie, no skipping 👑

• total — the grand total, like the big boss counter: total number of interrupts generated so far 🔥
• rxok — receive that went through with literally no errors, slay ✨
• rxlp — receive with low priority RX
• rxhp — receive with high priority — and heads up, uapsd only 🫶
• rxeol — receive where there are no more RXDESC available 😭
• rxorn — receive FIFO overrun, not the vibe
• txok — transmit completed at the requested rate, ate 💅
• txeol — transmit end-of-list counter (this one's in the struct, the manpage doesn't spell it out for us, so we don't invent lore 🙈)
• txurn — transmit FIFO underrun, the other kind of oops
• mib — MIB regs reaching its threshold 👀
• rxphyerr — receive with phy errors
• rx_keycache_miss — receive with key cache misses, tragic
• swba — Software Beacon Alert 🚨
• bmiss — Beacon Miss, honestly relatable
• bnr — Beacon Not Ready, also relatable
• cst — Carrier Sense TImeout
• gtt — Global TX Timeout
• tim — receive beacon TIM occurrence
• cabend — receive End of CAB traffic
• dtimsync — DTIM sync lossage
• dtim — receive Beacon with DTIM
• bb_watchdog — Baseband watchdog 🐶
• tsfoor — TSF out of range, and okay this one's a whole paragraph so buckle up: it indicates that the corrected TSF received from a beacon differs from the PCU's internal TSF by more than a (programmable) threshold 👑
• mci — MCI interrupt, specific to MCI based BTCOEX chipsets (niche but we respect it)
• gen_timer — Generic hardware timer interrupt ⏰
• local_timeout — Internal bus timeout.

real talk: the manpage only spells out descriptions for the members listed above — the rest of the fields (sync_cause_all, sync_rtc_irq, sync_mac_irq, eeprom_illegal_access, apb_timeout, pci_mode_conflict, host1_fatal, host1_perr, trcv_fifo_perr, radm_cpl_ep, radm_cpl_dllp_abort, radm_cpl_tlp_abort, radm_cpl_ecrc_err, radm_cpl_timeout, pm_access, mac_awake, mac_asleep, mac_sleep_access) are just vibing in the struct with no written explanation. we don't make stuff up in this group chat, bestie 🫶
