enable_tcs_irq(9)

✨ enable_tcs_irq — Kernel API Manual, section 9 ✨

okay bestie, welcome to the enable_tcs_irq(9) page 💅 it's short, it's specific, and it's literally about flipping interrupts on a TCS. Manual name? Kernel API Manual, right up top where you need it 🫶

🌸 NAME 🌸

enable_tcs_irq — Enable or disable interrupts on the given TCS.

🎀 SYNOPSIS 🎀

void enable_tcs_irq (struct rsc_drv *drv , int tcs_id , bool enable );

🦋 ARGUMENTS 🦋

• drv — The controller.
• tcs_id — The global ID of this TCS.
• enable — If true then enable; if false then disable.

💖 DESCRIPTION 💖

okay so the whole vibe: we only ever call this when we borrow a wake TCS for an active-only transfer. For active-only TCSes, interrupts are always left enabled. That's the situation, no cap ✨
