STRUCT TPDM_DRVDATA(9)

okay so bestie, you're looking at the struct tpdm_drvdata page from the Kernel API Manual, section 9, no cap. It's giving specifics associated to an TPDM component — literally the little data bundle for one TPDM component, and we're obsessed. 💅✨

🌸 NAME 🌸

struct tpdm_drvdata — specifics associated to an TPDM component. That's the whole vibe, periodt. 🫶

🦋 SYNOPSIS 🦋

Here's the exact struct, bestie — every field, every space, no edits, fr fr:

       struct tpdm_drvdata {
           void __iomem            *base;
           struct device           *dev;
           struct coresight_device *csdev;
           spinlock_t spinlock;
           bool enable;
           unsigned long           datasets;
           struct dsb_dataset      *dsb;
           struct cmb_dataset      *cmb;
           u32 dsb_msr_num;
           u32 cmb_msr_num;
           u8 traceid;
        };

💖 Members 💖

okay so each member is doing its own little main character thing:

• base — memory mapped base address for this component. 📍
• dev — The device entity associated to this component. 🫶
• csdev — component vitals needed by the framework. 🧚
• spinlock — lock for the drvdata value. 🔒
• enable — enable status of the component. ✅
• datasets — The datasets types present of the TPDM. 🗂️
• dsb — Specifics associated to TPDM DSB. ✨
• cmb — Specifics associated to TPDM CMB. ✨
• dsb_msr_num — Number of MSR supported by DSB TPDM 🔢
• cmb_msr_num — Number of MSR supported by CMB TPDM 🔢
• traceid — Trace ID of the path. 🧭
