STRUCT SCMI_VOLTAGE_PROTO_OPS(9)

💅 NAME 💅

okay so bestie, welcome to struct scmi_voltage_proto_ops — this is the Kernel API Manual, section 9, and it's literally the struct that holds all the various operations that the SCMI Voltage Protocol hands you. like, every move this protocol can make lives in here. periodt.

✨ SYNOPSIS ✨

no cap, here's the whole thing, character for character:

struct scmi_voltage_proto_ops {
    int (*num_domains_get)(const struct scmi_protocol_handle *ph);
    const struct scmi_voltage_info __must_check *(*info_get) (const struct scmi_protocol_handle *ph, u32 domain_id);
    int (*config_set)(const struct scmi_protocol_handle *ph, u32 domain_id, u32 config);
  #define SCMI_VOLTAGE_ARCH_STATE_OFF             0x0;
  #define SCMI_VOLTAGE_ARCH_STATE_ON              0x7;
    int (*config_get)(const struct scmi_protocol_handle *ph, u32 domain_id, u32 *config);
    int (*level_set)(const struct scmi_protocol_handle *ph, u32 domain_id, enum scmi_voltage_level_mode mode, s32 volt_uV);
    int (*level_get)(const struct scmi_protocol_handle *ph, u32 domain_id, s32 *volt_uV);
 };

it's giving function-pointer buffet and honestly? we ate. 🍓

🎀 MEMBERS 🎀

one bullet per icon, let's go:

• num_domains_get — gets you the count of voltage domains provided by SCMI. like a headcount but for voltage domains 💖
• info_get — gets the information of the specified domain. you want the tea on a domain? this is the tea.
• config_set — sets the config for the specified domain. you're the main character, you decide.
• config_get — gets the config of the specified domain. reading the room, essentially.
• level_set — sets the voltage level for the specified domain. yes bestie, we're adjusting.
• level_get — gets the voltage level of the specified domain. what's the vibe? this tells you. ✨
