💖 buffer_icap_set_configuration — Kernel API Manual 💖

okay so bestie, welcome to the little corner of the kernel where we yeet partial bitstreams into an FPGA, and honestly? it's giving iconic. this is a page from the Kernel API Manual, and it's about one function, but she's a real one. let's go 💅

✨ NAME ✨

buffer_icap_set_configuration — load a partial bitstream from system memory. that's it, that's the whole vibe. memory ➡️ bitstream ➡️ configured. slay 🎀

🌸 SYNOPSIS 🌸

int buffer_icap_set_configuration (struct hwicap_drvdata *drvdata , u32
*data , u32 size );

no cap, that's the whole signature. she returns an int, she takes three things, and she's ready to go ✨

🦋 ARGUMENTS 🦋

  • drvdata — a pointer to the drvdata. yes bestie, that's the driver data, she's gotta know who she's working with 🫶
  • data — the kernel address of the partial bitstream. this is where the good stuff lives, in kernel memory specifically 🔥
  • size — the size of the partial bitstream in 32-bit words. and yes, 32-bit words, not bytes, don't come for me, that's literally what it says 💀
fr fr, double-check that unit before you pass anything. size is in 32 bit words. iykyk 🙈

👑 SEE ALSO 👑

the source herself lives right here in the kernel tree, go say hi:

  • Kernel file ./drivers/char/xilinx_hwicap/buffer_icap.c

and her whole friend group, in exactly this order:

one big happy hwicap family, main character energy all around 🌈

and that's the page, bestie 💜 this little gem comes from ./drivers/char/xilinx_hwicap, dated October 2026 — go off, you're now officially informed 🌟💅
