🦋 SYNOPSIS 🦋

it's giving very demure, very mindful:

int qcom_smem_dram_get_hbb (void );

🌸 ARGUMENTS 🌸

🔥 CONTEXT 🔥

real talk: check qcom_smem_is_available before calling this function. 👑

Because __dram * is initialized by smem_dram_parse, which is in turn called from qcom_smem_probe, __dram will only be NULL if the data couldn't have been found/interpreted correctly. iykyk. 💀

⭐ RETURN ⭐

highest bank bit on success, -ENODATA on failure. slay when it works, sad little -ENODATA when it doesn't. 😭
