STRUCT SCP_DOMAIN_DATA(9)

👑 struct scp_domain_data(9) 👑

okay so bestie, this is the Kernel API Manual page for struct scp_domain_data(9), and it’s lowkey iconic 💖 It’s literally all about the scp domain data for the power on/off flow. No cap, tiny struct, big main-character energy ✨

✨ NAME ✨

struct scp_domain_data — scp domain data for power on/off flow 🦋

🌸 SYNOPSIS 🌸

       struct scp_domain_data {
           const char *name;
           u32 sta_mask;
           int ctl_offs;
           u32 sram_pdn_bits;
           u32 sram_pdn_ack_bits;
           u32 bus_prot_mask;
           enum clk_id clk_id[MAX_CLKS];
           u8 caps;
        };

💅 Members 💅

• name — the domain name, like obviously what this domain is called 💁‍♀️
• sta_mask — the mask for the power on/off status bit ⚡
• ctl_offs — the offset for the main power control register 🎛️
• sram_pdn_bits — the mask for sram power control bits 🧠
• sram_pdn_ack_bits — the mask for sram power control acked bits ✅
• bus_prot_mask — the mask for single step bus protection 🛡️
• clk_id — the basic clocks required by this power domain, stored as an array of enum clk_id with MAX_CLKS slots 🕰️
• caps — the flag for active wake-up action 👀
