STRUCT DMUB_SRV_BASE_FUNCS(9)

🎀 NAME 🎀

okay so this is the struct dmub_srv_base_funcs(9) page from the Kernel API Manual, and it’s literally about Driver specific base callbacks. The struct is struct dmub_srv_base_funcs — that’s the name, bestie, and the whole description is “Driver specific base callbacks.” No cap, that’s the assignment. 🫶

✨ SYNOPSIS ✨

Here’s the struct in all its glory, exactly as it appears:

       struct dmub_srv_base_funcs {
           uint32_t (*reg_read)(void *ctx, uint32_t address);
           void (*reg_write)(void *ctx, uint32_t address, uint32_t value);
        };

💅 Members 💅

Two members, two hooks, periodt:

• reg_read — Hook for reading a register. Return: The 32-bit register value from the given address.
• reg_write — Hook for writing a value to the register specified by address.
