acpi_nhlt_endpoint_match(9)

💖 Kernel API Manual 💖

okay so bestie, welcome to the acpi_nhlt_endpoint_match(9) page — yes, that whole name is the flex, and this function is literally giving “does this endpoint pass the vibe check?” energy. Let’s get into it. 🫶

✨ NAME ✨

acpi_nhlt_endpoint_match — verify if an endpoint matches criteria. periodt. 💅

🦋 SYNOPSIS 🦋

bool acpi_nhlt_endpoint_match (const struct acpi_nhlt_endpoint *ep , int
       link_type , int dev_type , int dir , int bus_id );

🌸 ARGUMENTS 🌸

• ep — the endpoint to check. the main character we’re judging 💖
• link_type — the hardware link type, e.g.: PDM or SSP. basically what kind of link situation we’re looking at.
• dev_type — the device type. 🎀
• dir — stream direction.
• bus_id — the ID of virtual bus hosting the endpoint. 🦋

💜 DESCRIPTION 💜

okay so here’s the tea: link_type, dev_type, dir, or bus_id may be set to a negative value to ignore the parameter when matching. it’s giving “skip this filter, bestie” energy. ✨

🔥 RETURN 🔥

• true if endpoint matches specified criteria. slay.
• false otherwise. not slay, but valid. 💀
