doc_delay(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸŽ€ NAME πŸŽ€

okay bestie, this is doc_delay(9) from the Kernel API Manual, and its whole job is to delay docg3 operations. that’s it, that’s the name πŸ’…βœ¨

✨ SYNOPSIS ✨

void doc_delay (struct docg3 *docg3 , int nbNOPs );

πŸŽ€ ARGUMENTS πŸŽ€

  • docg3 β€” the device. the actual struct docg3 we’re working with, no cap.
  • nbNOPs β€” the number of NOPs to issue. yes, you’re literally telling it how many NOPs to send πŸ”₯

πŸ’… DESCRIPTION πŸ’…

okay so here’s the tea: no specification is available, which means the right timings between chip commands are unknown. 😭 like, we do not have the official timing info, bestie.

The only available piece of information is the observed nops on a working docg3 chip. that’s the one clue we have β€” observed NOPs from a chip that actually works πŸ•΅οΈβ€β™€οΈβœ¨

So doc_delay relies on a busy loop of NOPs, instead of scheduler friendlier msleep functions or blocking mdelay. it’s giving β€œspin the NOPs until the timing vibes are right” rather than β€œgo to sleep and let the scheduler handle it.” periodt πŸ’€

catch you later, bestie β€” this page comes from ./drivers/mtd/devices, dated October 2026, and it’s the doc_delay(9) manual. mwah πŸ’–βœ¨
