mips_gic_vx_map_reg(9)

💅 mips_gic_vx_map_reg(9) — from the Kernel API Manual, bestie 💖

okay so picture this: it's a kernel manual page, it's about MIPS GICs, and it's lowkey kind of a baddie. this is mips_gic_vx_map_reg, and we're gonna get you fluent in it ✨

---

🌸 NAME 🌸

mips_gic_vx_map_reg — returns the GIC_Vx_<intr>_MAP register offset. that's the whole job. she's a one-line icon 👑

---

🦋 SYNOPSIS 🦋

unsigned int mips_gic_vx_map_reg (enum mips_gic_local_interrupt intr );

---

🎀 ARGUMENTS 🎀

• intr — a GIC local interrupt. that's it, that's the whole argument. give her one (1) interrupt and she'll do the rest 🫶

---

💜 DESCRIPTION 💜

so what she actually does is determine the index of the GIC_VL_<intr>_MAP or GIC_VO_<intr>_MAP register inside the block of GIC map registers. like, she's the friend who knows exactly where everyone's sitting at the table 💅

and here's the tea: it's almost the same order as the interrupts in the pending & mask registers — the one used by enum mips_gic_local_interrupt — BUT it moves the FDC interrupt, and because of that it offsets all the interrupts after it... 😭 so close to being identical and yet. not.

the return value is suitable for use with the (read|write)_gic_v[lo]_map accessor functions. so like, you get the index from her, you hand it straight to those accessors, and everything slays ✨

---

🔥 RETURN 🔥

the map register index corresponding to intr. no cap, that's literally the whole return value 👑

fr fr bestie, read the whole list. the FDC one especially — she's the reason the ordering shifts, remember? iykyk 💀
