✨ enable_dbc(9) ✨

okay so bestie, this page comes from the Kernel API Manual, and it's here to explain enable_dbc — the function that puts the user context back so a DBC can be enabled. very main character energy for a kernel API, ngl. 💅

🎀 NAME 🎀

enable_dbc — enable the DBC. 💖

Real talk: DBCs get disabled by removing the context of user, so to enable one, you add user context back to the DBC. This function trusts the DBC ID passed and expects the DBC to be disabled. periodt.

🌈 SYNOPSIS 🌈

void enable_dbc (struct qaic_device *qdev , u32 dbc_id , struct qaic_user *usr );

🦋 ARGUMENTS 🦋

• qdev — qaic device handle. your entry point, basically. 🫶
• dbc_id — ID of the DBC. the one getting its enable vibe check.
• usr — User context. this is the context being added back, iykyk. 💫

👑 SEE ALSO 👑
