STRUCT QCOM_SMD_RPM(9)

💅 struct qcom_smd_rpm(9) — the Kernel API Manual, but make it make sense

okay so bestie, welcome to the Kernel API Manual entry for struct qcom_smd_rpm — literally the state of the rpm device driver. that's the whole vibe. one struct, five members, zero notes. let's get into it ✨

🦋 SYNOPSIS

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

struct qcom_smd_rpm {
    struct rpmsg_endpoint *rpm_channel;
    struct device *dev;
    struct completion ack;
    struct mutex lock;
    int ack_status;
 };

🎀 Members

so each of these is a little main character in the struct's story:

• rpm_channel — a reference to the smd channel. it's giving "the actual line of communication" 🫶
• dev — the rpm device. iconic, obviously.
• ack — the completion for acks. it's literally just sitting there waiting for the ✨ acknowledgment ✨
• lock — mutual exclusion around the send/complete pair. mutual exclusion!! she's keeping things from getting messy in there 💅
• ack_status — the result of the rpm request. the vibe check at the end of the day, iykyk

🌈 SEE ALSO

go check out the Kernel file ./drivers/soc/qcom/smd-rpm.c — that's where the real lore lives. and then these besties:

• struct qcom_rpm_header(9)
• struct qcom_rpm_request(9)
• struct qcom_rpm_message(9)
• qcom_rpm_smd_write(9)

ok that's the whole page fr fr, it's short and sweet and honestly ate 💀 no bugs listed, no warnings, no exit statuses — just vibes and a struct.

and that's a wrap bestie 💖 this was the struct qcom_smd_rpm(9) page from ./drivers/soc/qcom, dated October 2026, and we are SO done here. slay 🎀✨🌸
