STRUCT DPU_INTR_REG(9)
π struct dpu_intr_reg(9) β the Kernel API Manual, bestie edition π
okay so picture this: you're deep in the dpu source, and you keep bumping into this little struct called dpu_intr_reg. It lives in section 9 of the Kernel API Manual, and it is literally just... an array of DPU register sets β¨ That's the whole vibe. It's the group chat of offsets β three members, all besties, all pointing at different interrupt registers.
No cap, it's tiny. But it's iconic.
π¦ SYNOPSIS π¦
struct dpu_intr_reg {
u32 clr_off;
u32 en_off;
u32 status_off;
};
that's it. that's the struct. she's small but she's booked and busy π
πΈ Members πΈ
clr_offβ the offset to theCLEARreg π₯ lowkey your "undo" button, address-wiseen_offβ the offset to theENABLEreg π where you tell the interrupt to wake up and show upstatus_offβ the offset to theSTATUSreg π the one that tells you what's actually going on β main character energy fr fr
each one is a u32, each one is an offset, and together they're giving full register-set realness π«Ά
π§ SEE ALSO π§
the kernel file you wanna keep in the group chat:

ngl if you're reading this struct you're probably about to touch interrupts β read the SEE ALSO list before you do anything β¨π¦
