STRUCT SVS_BANK_PDATA(9)

👑 struct svs_bank_pdata — SVS Bank immutable config parameters 💅

okay so welcome to the Kernel API Manual, section 9 bestie — this is the page for struct svs_bank_pdata, aka the immutable config parameters for an SVS Bank. "Immutable" meaning you set these up and then leave them alone, no cap. Let's get into it ✨

🌸 SYNOPSIS 🌸

struct svs_bank_pdata {
    const struct svs_fusemap *dev_fuse_map;
    char *buck_name;
    char *tzone_name;
    u32 age_config;
    u32 ctl0;
    u32 dc_config;
    u32 int_st;
    u32 turn_freq_base;
    u32 tzone_htemp;
    u32 tzone_ltemp;
    u32 volt_step;
    u32 volt_base;
    u16 tzone_htemp_voffset;
    u16 tzone_ltemp_voffset;
    u8 chk_shift;
    u8 cpu_id;
    u8 opp_count;
    u8 vboot;
    u8 vco;
    u8 sw_id;
    u8 type;
    void (*set_freq_pct)(struct svs_platform *svsp, struct svs_bank
*svsb);
    void (*get_volts)(struct svs_platform *svsp, struct svs_bank *svsb);
 };

like look at all those fields. it's giving organized. it's giving I know exactly what I am. we stan a well-structured struct 🫶

✨ Members ✨

• dev_fuse_map — the bank's fuse map data. the origin lore, the blueprint, the fuse map 💖
• buck_name — the regulator name. what the regulator is called, iykyk.
• tzone_name — the thermal zone name. yes it has a name, and yes it's iconic.
• age_config — the bank's age configuration. the bank is aging gracefully, periodt.
• ctl0 — TS-x selection. that's the whole description, bestie, don't @ me.
• dc_config — the bank's dc configuration.
• int_st — the bank's interrupt identification. so you know which interrupt it is 🔥
• turn_freq_base — the reference frequency for the 2-line turn point. this one's a base, it's the reference, it's doing main character energy.
• tzone_htemp — the thermal zone high temperature threshold. HOT 🔥
• tzone_ltemp — the thermal zone low temperature threshold. and then... not hot 💀
• volt_step — the bank's voltage step.
• volt_base — the bank's voltage base.
• tzone_htemp_voffset — the thermal zone high temperature voltage offset.
• tzone_ltemp_voffset — the thermal zone low temperature voltage offset. matching set, we love symmetry 💅
• chk_shift — the bank's chicken shift. no I'm not making that up, that's literally what it's called, and honestly? iconic 🐔
• cpu_id — the CPU core ID, for SVS CPU bank use only. read the fine print bestie, only 🎀
• opp_count — the bank's opp count.
• vboot — the voltage request for bank init01 only. again: ONLY. 🙈
• vco — the bank's VCO value.
• sw_id — the bank's software identification.
• type — the SVS Bank Type (1 or 2-line) and Role (high/low). so many layers, so much range 🌈
• set_freq_pct — function pointer to set bank frequency percent table. it's a pointer, it's a function, it sets the table, it slays.
• get_volts — function pointer to get bank voltages. the getter to the other one's setter, we love a duo 🫶

💜 SEE ALSO 💜

go read these next, bestie, they're all in the Kernel file ./drivers/soc/mediatek/mtk-svs.c and they're literally the whole friend group:

• enum svsb_sw_id(9)
• enum svsb_type(9)
• enum svsb_phase(9)
• struct svs_platform(9)
• struct svs_bank(9)

that's the whole page! no notes, she ate 💅 this lil slice of the Kernel API Manual lives over in ./drivers/soc/mediatek, and it was dated October 2026 — so yeah, future iconic behavior ⭐ bye bestie, go configure a bank responsibly 🦋
