ice_sched_get_ena_tc_bitmap(9)

💖 ice_sched_get_ena_tc_bitmap(9) 💖

okay so bestie, this one is straight out of the Kernel API Manual and it's giving "small function, big responsibilities" energy. let's get into it 🫶

---

✨ NAME ✨

ice_sched_get_ena_tc_bitmap — get enabled TC bitmap 👑

---

🌸 SYNOPSIS 🌸

void ice_sched_get_ena_tc_bitmap (struct ice_port_info *pi , unsigned
long *tc_bitmap , unsigned long *ena_tc_bitmap );

---

🎀 ARGUMENTS 🎀

no cap, there are exactly three and you need all of them:

• pi — the port info struct, your main character 🦋
• tc_bitmap — an 8 bits TC bitmap to check, like, the one you're inspecting 💅
• ena_tc_bitmap — an 8 bits enabled TC bitmap to return, this is where the answer lives ✨

---

💜 DESCRIPTION 💜

so what does it actually do? This function returns the enabled TC bitmap in the variable ena_tc_bitmap. Some TCs may be missing — and that's fine, it just returns the enabled ones. lowkey iconic of it, honestly 🌈

⚠️ real talk though: this function needs to be called with the scheduler lock held. not optional, not vibe-based, just held. fr fr 🔒

🦋 SEE ALSO 🦋

the source lives right here in the kernel, bestie:

./drivers/net/ethernet/intel/ice/ice_sched.c

like I said. huge. but every single one of them matters, so no skipping 💀

and that's the whole page, bestie — go get those enabled TCs 💅✨
