💅 asd_read_reg_string(9) — the Kernel API Manual, bestie edition 🎀

okay so picture this: you're in the kernel, you're in the aic94xx driver, and you need bytes from io space memory. that's the whole vibe of this page. it's living in the Kernel API Manual and it's literally called asd_read_reg_string, and we're gonna get you fluent in it, no cap. ✨

🌸 NAME 🌸

asd_read_reg_string — read a string of bytes from io space memory 🦋

like, that's it. that's the mission statement. a whole string of bytes, straight out of io space memory. iconic behavior honestly.

---

✨ SYNOPSIS ✨

void asd_read_reg_string (struct asd_ha_struct *asd_ha , void *dst , u32
offs , int count );

so yes, it returns void — nothing gets handed back to you, the data just gets placed into your buffer and you move on with your life. main character energy: it does the work, it doesn't need credit. 💅

fr fr, keep that spacing exactly as it is up there — manpage synopsis lines are sacred, don't be out here "fixing" them.

🫶 ARGUMENTS 🫶

• asd_ha — pointer to host adapter structure. this is your little VIP pass to the host adapter, you gotta hand it over so it knows whose io space we're vibing with 💖
• dst — pointer to a destination buffer where data will be written to. this is the cute little bucket where the bytes are gonna land. your buffer, your problem, your moment ✨
• offs — start offset (register) to read from. it's giving "where do we begin" — the starting point, the register we're pulling from, the coordinates of the whole operation 🎀
• count — number of bytes to read. how many bytes are we eating? this many. not one more, not one less 🍓

👑 SEE ALSO 👑

• Kernel file ./drivers/scsi/aic94xx/aic94xx_reg.c — the source file this bad boy lives in, go read it, it's right there 🧚
• asd_move_swb(9) — its sibling in the register-ops friend group 🌈
• asd_write_reg_string(9) — the other half of the duo, the writing one. yes they're a matching set, we love a balanced pair 💜

aaaand that's the page!! 🌟 shoutout to ./drivers/scsi/aic94xx for housing all this, dating all the way to October 2026, and the page itself is asd_read_reg_string(9) — go read some bytes bestie, you've got this 💖🦋✨
