πŸ’… wait_for_space(9) β€” Kernel API Manual, bestie edition ✨

Okay so real talk: this is wait_for_space from section 9 of the Kernel API Manual, and she is exactly what her name says. A little helper that patiently waits for room in a ring buffer. Iconic behavior honestly. Let's get into it 🫢


✨ NAME ✨

wait_for_space β€” check ring buffer free space. That's it, that's the whole gig πŸ’–


🌸 SYNOPSIS 🌸

int wait_for_space (struct fb_info *info , u32 space );

Literally just that. She takes two things and returns an int. No cap 🧚


πŸŽ€ ARGUMENTS πŸŽ€

  • info β€” okay so the manpage itself says -- undescribed -- and I'm not gonna lie to you bestie, that's all we get 😭 the original page gives us nothing here, so I'm giving you nothing here either. We respect the source. She's a mystery. Main character energy fr.
  • space β€” the amount of ringbuffer space needed, and it's measured in bytes. That's the whole vibe check right there ✨

πŸ¦‹ DESCRIPTION πŸ¦‹

So what does she do? The function waits until a free space from the ringbuffer is available. That's the tea, that's the function, periodt πŸ’…

Like, you want space in the ringbuffer? She'll wait for it. The space you passed in β€” in bytes β€” is the amount she's waiting on. Standing there. Being patient. An absolute queen πŸ‘‘


πŸ”₯ SEE ALSO πŸ”₯

The Kernel file, exactly where she lives:

./drivers/video/fbdev/i810/i810_accel.c

And her whole friend group, all in section 9:

Go say hi to all of them, they're lowkey iconic 🌈


ngl if you got here looking for lore about info, the page genuinely says -- undescribed --. Not my fault bestie, I'm just the messenger πŸ’€

Okay that's the whole page!! This little gem lives under ./drivers/video/fbdev/i810, and the manual dates her to October 2026 β€” wait_for_space(9), forever and always. Mwah πŸ’‹πŸŽ€βœ¨
