💅 zynqmp_pm_set_tcm_config — the kernel API manual, bestie edition

okay so this is a page from the Kernel API Manual and it's all about zynqmp_pm_set_tcm_config(9) — yes that's a mouthful, we're saying it with our whole chest 🫶

✨ NAME ✨

zynqmp_pm_set_tcm_config — configure TCM, that's literally the whole job 💅

🌸 SYNOPSIS 🌸

int zynqmp_pm_set_tcm_config (u32 node_id , enum rpu_tcm_comb tcm_mode
);

like, that's the shape of it. it returns an int, it takes two things, we move 🎀

🦋 ARGUMENTS 🦋

  • node_id — the Firmware specific TCM subsystem ID. it's the ID the firmware knows this TCM subsystem by, no cap 🪪
  • tcm_mode — the Argument 1 you pass to the requested IOCTL call, either PM_RPU_TCM_COMB or PM_RPU_TCM_SPLIT. pick one, bestie, those are the two vibes ✌️

💖 DESCRIPTION 💖

so what does this function do? it's used to set the RPU mode to split or combined. that's it, that's the tea ☕ two modes, one function, main character energy honestly 👑

🔥 RETURN 🔥

status: 0 for success, else failure. so if you get a 0 you ate, and if you don't… you did not eat 😭💀

🌈 SEE ALSO 🌈

the friend group is huge, buckle up babes, everyone's invited 🫶

like I said. everyone. every single one. we don't gatekeep here 💜

okay that's the whole page bestie, and real quick the cute little sign-off from the source at the bottom said ./drivers/firmware/xilinx with October 2026 on it, so yeah — that's where this came from and when it was dated 📅✨ mwah 💋
