DPNI_FS_OPT...TASH_CONTROL(9)

💅 DPNI_FS_OPT_SET_STASH_CONTROL 💅

Okay bestie, welcome to the Kernel API Manual — we're looking at DPNI_FS_OPT_SET_STASH_CONTROL today and it's giving very specific bit-field energy. ✨

🌸 NAME 🌸

DPNI_FS_OPT_SET_STASH_CONTROL — this one indicates whether the 6 lowest significant bits of FLC are used for stash control. No cap, that's the whole mood. 💖

When this flag is set, the 6 least significant bits in value are interpreted like this:

• bits 0-1 — tells you the number of 64 byte units of context that are stashed. In this case, the FLC value is interpreted as a memory address, excluding the 6 LS bits.
• bits 2-3 — tells you the number of 64 byte units of frame annotation to be stashed. Annotation is placed at FD[ADDR].
• bits 4-5 — tells you the number of 64 byte units of frame data to be stashed. Frame data is placed at FD[ADDR] + FD[OFFSET].

And listen, bestie: this flag is ignored if DPNI_FS_OPT_SET_FLC is not specified. That's the rule, periodt. 💀

✨ SYNOPSIS ✨

DPNI_FS_OPT_SET_STASH_CONTROL

Lowkey just the one symbol, bestie. 🫶
