STRUCT AMS(9)

💖 NAME 💖

okay so bestie, this is the <pink>struct ams(9)</pink> manual page, and the name is literally struct ams — it’s the structure that contains the necessary state for xilinx-ams to operate. no cap ✨

✨ SYNOPSIS ✨

here’s the whole struct, copied exactly because we do not mess with the code 💅

       struct ams {
           void __iomem *base;
           void __iomem *ps_base;
           void __iomem *pl_base;
           struct clk *clk;
           struct device *dev;
           struct mutex lock;
           spinlock_t intr_lock;
           unsigned int alarm_mask;
           unsigned int current_masked_alarm;
           u64 intr_mask;
           struct delayed_work ams_unmask_work;
        };

💅 Members 💅

okay so every single member, let’s go 🫶

• base — physical base address of device. it’s giving “where the device lives” energy 🏠
• ps_base — physical base address of PS device. yes, the PS one specifically 💜
• pl_base — physical base address of PL device. and this one is for PL, periodt ✨
• clk — clocks associated with the device. tick tock bestie ⏰
• dev — pointer to device struct. main character pointer energy 👑
• lock — to handle multiple user interaction. keeping things from getting messy 🎀
• intr_lock — to protect interrupt mask values. bodyguard for the mask values fr fr 🛡️
• alarm_mask — alarm configuration. alarm vibes configured here 🚨
• current_masked_alarm — currently masked due to alarm. yup, it’s masked right now because of alarm 😭
• intr_mask — interrupt configuration. interrupt config lives here 💥
• ams_unmask_work — re-enables event once the event condition disappears. it literally brings the event back when the condition is gone 🔁

🔥 SEE ALSO 🔥
