cs_slot_reset_locked(9)

💅 cs_slot_reset_locked — nope, wait, let's start with the NAME 💅

okay bestie, welcome to the cs_slot_reset_locked(9) page, straight out of the Kernel API Manual ✨ this one's a lil kernel function that resets a queue slot, and honestly? it's giving "small function, big responsibilities" energy 🎀

🦋 NAME 🦋

cs_slot_reset_locked — reset a queue slot. that's it. that's the whole vibe check 💜

🌸 SYNOPSIS 🌸

int cs_slot_reset_locked (struct panthor_device *ptdev , u32 csg_id ,
u32 cs_id );

so she takes three things and hands you back an int, periodt 💅

✨ ARGUMENTS ✨

• ptdev — the Device. like, the actual device. main character energy 🫶
• csg_id — Group slot. the group-level spot, iykyk 🌈
• cs_id — Queue slot. the queue-level spot inside it 🎀

🔥 DESCRIPTION 🔥

okay so here's what she does: she changes the queue slot state to STOP and suspends the queue timeout — but only if the queue is not blocked. not me adding conditions to my own reset 😭 read that again: if the queue is not blocked. blocked queue? she's not touching the timeout, bestie. respect the boundaries 💀

🚨 important caveat incoming: the group slot must have a group bound to it already (that's group_bind_locked). no group bound? bestie, that's not it. make sure it's bound first, fr fr 👑
