✨ asd_read_ocm_seg(9) ✨

okay so bestie, we're deep in the Kernel API Manual today and the vibe is very driver-dev summer ☀️ this one's asd_read_ocm_seg(9) and it's literally just here to read you a lil piece of on chip memory (OCM) 🍓 no cap, that's the whole gig.

🌸 NAME 🌸

asd_read_ocm_seg — read an on chip memory (OCM) segment 💅 like, it goes and fetches you a slice of OCM, periodt.

🎀 SYNOPSIS 🎀

int asd_read_ocm_seg (struct asd_ha_struct *asd_ha , void *buffer , u32
offs , int size );

that's the whole signature, copy it exactly bestie, don't be out here renaming things 🙈

🦋 ARGUMENTS 🦋

  • asd_ha — pointer to the host adapter structure ✨ this is the main character of the operation, lowkey the host adapter itself.
  • buffer — where to write the read data 💖 the data lands here, this is the destination, that's it, no notes.
  • offs — offset into OCM where to read from 🌸 so like, where in the OCM we're poking around.
  • size — how many bytes to read 👑 exactly how much data you're grabbing, fr fr.

💜 DESCRIPTION 💜

Return the number of bytes not read 💀 (yes, not read — read that twice, it's giving "we tell you what we missed").

Return 0 on success ✨ zero is the slay outcome here, that's the win condition, iykyk.
