STRUCT SMSM_ENTRY(9)

💖 struct smsm_entry(9) 💖

okay bestie, welcome to the Kernel API Manual page for struct smsm_entry — it’s giving per-remote-processor entry context, and we’re gonna read it together like a very niche group chat. no cap, every field is coming with us. ✨

💖 NAME 💖

struct smsm_entry — per remote processor entry context. that’s literally the whole NAME section, and honestly? iconic. 💅

✨ SYNOPSIS ✨

here’s the struct in all its literal glory — copy-paste energy, but make it kernel:

       struct smsm_entry {
           struct qcom_smsm *smsm;
           struct irq_domain *domain;
           unsigned long irq_enabled[BITS_TO_LONGS( 32)];
           unsigned long irq_rising[BITS_TO_LONGS( 32)];
           unsigned long irq_falling[BITS_TO_LONGS( 32)];
           unsigned long last_value;
           u32 *remote_state;
           u32 *subscription;
        };

🌸 Members 🌸

• smsm — back-reference to driver context. lowkey the struct’s little link back home 🫶
• domain — IRQ domain for this entry, if representing a remote system. highkey specific, and we love that 🎀
• irq_enabled — bitmap of which state bits IRQs are enabled. yes ma’am, bitmaps 💅
• irq_rising — bitmap tracking if rising bits should be propagated. rising bits stay booked and busy ✨
• irq_falling — bitmap tracking if falling bits should be propagated. falling bits also have main character energy 😌
• last_value — snapshot of state bits last time the interrupts where propagated. keeping that original “where” exactly, bestie 😭
• remote_state — pointer to this entry's state bits. pointer era 🔥
• subscription — pointer to a row in the subscription matrix representing this entry. matrix row representation, periodt 🌈
