DFL_FPGA_PORT_UINT_SET_IRQ(9)

NAME ✨

Okay so bestie, this is DFL_FPGA_PORT_UINT_SET_IRQ(9) from the Kernel API Manual, and its whole name/definition is literally:

DFL_FPGA_PORT_UINT_SET_IRQ - _IOW(DFL_FPGA_MAGIC, DFL_PORT_BASE + 8, struct dfl_fpga_irq_set)

Not me being obsessed with a kernel page, but here we are 💅.

SYNOPSIS 🦋

No extra drama, just:

DFL_FPGA_PORT_UINT_SET_IRQ

---

DESCRIPTION 💖

If evtfds[n] is valid, this sets the fpga AFU interrupt trigger. If evtfds[n] is a negative value, it unsets the related interrupt trigger. That’s the vibe: valid means set, negative means unset, no cap 🫶.

---

RETURN 🌈

Returns 0 on success, and -errno on failure. Periodt ✨.
