💅 sbi_remote_hfence_vvma(9) — the sbi_remote_hfence_vvma page, bestie edition

okay so this is a page from the Kernel API Manual (the sbi_remote_hfence_vvma(9) one, yes the name is a mouthful, we love her anyway 🎀) and it's lowkey about firing off HFENCE.VVMA instructions on a bunch of remote harts for the current guest virtual address range. iconic RISC-V behavior ngl.

✨ NAME ✨

sbi_remote_hfence_vvma — Execute HFENCE.VVMA instructions on given remote harts for the current guest virtual address range. that's the whole vibe, no cap 🦋

🌸 SYNOPSIS 🌸

int sbi_remote_hfence_vvma (const struct cpumask *cpu_mask , unsigned
       long start , unsigned long size );

literally just three args and an int return, she's a whole main character 👑

🫶 ARGUMENTS 🫶

  • cpu_mask — A cpu mask containing all the target harts. iykyk, this is your guest list for the fence party 💌
