scmi_is_transport_atomic(9)

🌸 NAME 🌸

okay so bestie, this is the Kernel API Manual page for scmi_is_transport_atomic(9) — literally the method to check if the underlying transport for an SCMI instance is configured as atomic. no cap, that's the vibe. 💅✨

✨ SYNOPSIS ✨

bool scmi_is_transport_atomic (const struct scmi_handle *handle ,
       unsigned int *atomic_threshold );

🎀 ARGUMENTS 🎀

• handle — a reference to the SCMI platform instance. like, which SCMI platform we're checking, bestie. 🫶
• atomic_threshold — an optional return value for the system wide currently configured threshold for atomic operations. optional, so it's a return-value spot for that threshold — iykyk. ✨

🌈 RETURN 🌈

Returns True if transport is configured as atomic. periodt. 💖
