🌸 xvcu_write(9) 🌸

okay so bestie, welcome to xvcu_write(9) β€” it's from the Kernel API Manual and it's literally the tiniest little function with the biggest "i'm helping" energy. it writes to the VCU register space. that's it. that's the whole vibe. πŸ’…


✨ NAME ✨

xvcu_write β€” write to the VCU register space 🫢

like, you point it at the register space and it puts a value there. iconic behavior honestly.


πŸ¦‹ SYNOPSIS πŸ¦‹

void xvcu_write (void __iomem *iomem , u32 offset , u32 value );

no cap, that's the whole signature. three arguments, returns void, zero drama.


πŸŽ€ ARGUMENTS πŸŽ€

  • iomem β€” the vcu reg space base address πŸ’– this is your starting point, your home base, the address of the register space you're poking at.
  • offset β€” the vcu reg offset from base ✨ how far past iomem you're wandering to find the exact register you want.
  • value β€” the value to write 🌸 the actual thing getting dropped into that register. main character of the operation, lowkey.
