smsm_get_size_info(9)

🌸 smsm_get_size_info 🌸

okay bestie, welcome to the Kernel API Manual, where we're decoding smsm_get_size_info(9) and honestly it's giving “small function, important little mission” energy 🎀

✨ NAME ✨

smsm_get_size_info — parse the optional memory segment for sizes. periodt 💅

💖 SYNOPSIS 💖

int smsm_get_size_info (struct qcom_smsm *smsm );

🎀 ARGUMENTS 🎀

• smsm — the smsm driver context. That's it, that's the whole argument, and she's iconic 🫶

🦋 DESCRIPTION 🦋

okay so the way that this works: it attempts to acquire the number of hosts and entries from the optional shared memory location. Not being able to find this segment should indicate that we're on a older system where these values was hard coded to SMSM_DEFAULT_NUM_ENTRIES and SMSM_DEFAULT_NUM_HOSTS.

Returns 0 on success, negative errno on failure. no cap, fr fr 😭
