STRUCT R9A06G032_GATE(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸŽ€ NAME πŸŽ€

struct r9a06g032_gate β€” clock-related control bits πŸ’… (yes bestie, this is from the Kernel API Manual, we're doing real kernel hours now)


✨ SYNOPSIS ✨

struct r9a06g032_gate {
    struct regbit gate, reset, ready, midle  ;
 };

🫢 Members 🫢

  • gate β€” clock enable/disable, the whole point tbh πŸ‘‘
  • reset β€” clock module reset, and it's active low so lowkey mind the polarity πŸ™ˆ
  • ready β€” enables NoC forwarding of read/write requests to device, (eg. device is ready to handle read/write requests) β€” like it's saying "i'm up, send me stuff" fr fr
  • midle β€” request to idle the NoC interconnect, nap time for the master 😴

🌈 Description 🌈

So like, each of these fields describes a single bit in a register, which controls some aspect of clock gating. That's the whole vibe. πŸ¦‹

The gate field is mandatory, no cap β€” this one enables/disables the clock, it's the main character. The other fields are optional, with zero indicating "not used" (so a zero there is literally just "ignore me" πŸ’€).

In most cases there is a reset bit which needs to be de-asserted to bring the module out of reset. De-asserted, bestie, pay attention. ✨

Modules may also need to signal when they are ready to handle requests (read/writes) from the NoC interconnect β€” that's your ready bit doing its little job 🫢.

Similarly, the midle bit is used to idle the master. Everybody needs a break sometimes, even the interconnect. 🌸

okay that's the whole page, you ate that πŸ’… no additional lore, go touch some registers (carefully, and remember active low 🌸)
