STRUCT SBSA_GWDT(9)

💖 struct sbsa_gwdt(9) 💖

okay so bestie, welcome to the Kernel API Manual 🎀 — yes that's the whole manual name, we're fancy here. today's main character is struct sbsa_gwdt, which is literally the Internal representation of the SBSA GWDT. that's the NAME section, done, slay ✨

✨ SYNOPSIS ✨

here's the whole vibe, no cap, copy it exactly:

struct sbsa_gwdt {
    struct watchdog_device  wdd;
    u32 clk;
    int version;
    bool need_ws0_race_workaround;
    void __iomem            *refresh_base;
    void __iomem            *control_base;
 };

like, look at her. six fields. she's giving organized. 🦋

okay now the part where we meet everybody in the group chat one by one 💅

• wdd — the kernel watchdog_device structure. this is the actual watchdog device vibes, the whole point of the struct fr fr.
• clk — stores the System Counter clock frequency, in Hz. yes, Hz. numbers girlies rise 🙈
• version — stores the architecture version. which version? the architecture version. that's the lore. 👑
• need_ws0_race_workaround — this one's name is a whole paragraph already, and it's a bool that indicates whether to adjust wdd->timeout to avoid a race with WS0. like, it literally tells you if we're doing the race workaround or not. highkey important, don't sleep on her 😭
• refresh_base — Virtual address of the watchdog refresh frame. virtual, not real. dream address. ✨
• control_base — Virtual address of the watchdog control frame. the control freak sibling of the refresh frame, we respect her 💜

lowkey note bestie: refresh_base and control_base are both void __iomem *, so like, don't go dereferencing them like regular pointers, iykyk 🔥

🌈 SEE ALSO 🌈

• Kernel file ./drivers/watchdog/sbsa_gwdt.c — go read the source, that's where all the real tea is 🍓

and that's the whole page bestie, you ate that 🫶 this one came from the ./drivers/watchdog directory, dated October 2026, and the header said struct sbsa_gwdt(9) just so you know exactly which page you're on. mwah. 💖🌸
