STRUCT XPSGTR_DEV(9)

🎀 struct xpsgtr_dev(9) 🎀

okay so bestie, welcome to the Kernel API Manual entry for struct xpsgtr_dev — literally the representation of a ZynMP GT device. no cap, this is the whole struct vibe check 💅

✨ NAME ✨

struct xpsgtr_dev — representation of a ZynMP GT device 🦋

🦋 SYNOPSIS 🦋

struct xpsgtr_dev {
    struct device *dev;
    void __iomem *serdes;
    void __iomem *siou;
    struct mutex gtr_mutex;
    struct xpsgtr_phy phys[NUM_LANES];
    struct clk *clk[NUM_LANES];
    bool tx_term_fix;
    unsigned int saved_icm_cfg0;
    unsigned int saved_icm_cfg1;
    u32 *saved_regs;
 };

🌸 Members 🌸

• dev — pointer to device. the main-character pointer, periodt 💖
• serdes — serdes base address. yes, the serdes base address, exactly as it sounds ✨
• siou — siou base address. another base address, another lil' icon 🎀
• gtr_mutex — mutex for locking. it does the locking thing, fr fr 🔒
• phys — PHY lanes. the PHY lanes are in here 🌈
• clk — reference clocks. reference clocks, slay ⏰
• tx_term_fix — fix for GT issue. it's giving "fix for GT issue" 💅
• saved_icm_cfg0 — stored value of ICM CFG0 register. stored value, saved for later 🫶
• saved_icm_cfg1 — stored value of ICM CFG1 register. yes bestie, CFG1 is its own whole thing 😭
• saved_regs — registers to be saved/restored during suspend/resume. these registers get saved and restored during suspend/resume, no cap 🔥
