💅 epf_ntb_mw_bar_clear(9) — like, the Kernel API Manual, bestie

okay so. welcome to the Kernel API Manual, specifically the page for epf_ntb_mw_bar_clear ✨ this one's short and sweet and honestly kinda iconic for it.

🌸 NAME 🌸

epf_ntb_mw_bar_clear — clears Memory window BARs. that's it. that's the whole job. she's a one-task queen 👑

🎀 SYNOPSIS 🎀

void epf_ntb_mw_bar_clear (struct epf_ntb *ntb , int num_mws );

so she returns void (nothing back, no receipts, no drama) and takes a struct epf_ntb * plus an int. that's the whole signature, no cap 🫶

🦋 ARGUMENTS 🦋

  • ntb — the NTB device that facilitates communication between HOST and VHOST. like, she's the whole reason these two are even talking to each other 💬
  • num_mws — the number of Memory window BARs that to be cleared. yes. that many. exactly that many 💅
ngl this one's a tiny page, so there's really not much more to say — two args, one job, zero complications 🧚
