efx_nic_update_stats(9)

✨ NAME ✨ — from the Kernel API Manual, bestie 🫶

okay so efx_nic_update_stats(9) is the function whose whole vibe is Convert statistics DMA buffer to array of u64 — that’s the main character energy here, periodt. 💅

📜 SYNOPSIS ✨

void efx_nic_update_stats (const struct efx_hw_stat_desc *desc , size_t
count , const unsigned long *mask , u64 *stats , const void *dma_buf ,
bool accumulate );

🌸 ARGUMENTS 🌸

• desc — this is the array of struct efx_hw_stat_desc that describes the DMA buffer layout, okay? DMA widths of 0, 16, 32 and 64 are supported; where the width is specified as 0, the corresponding element of stats is not updated. Not me pointing at the zero width like 👀.
• count — length of the desc array. literally the count of desc, bestie.
• mask — bitmask of which elements of desc are enabled. ✨
• stats — buffer to update with the converted statistics. The length of this array must be at least count. no cap, that length requirement is real.
• dma_buf — DMA buffer containing hardware statistics. 🫶
• accumulate — if set, the converted values will be added rather than directly stored to the corresponding elements of stats. it’s giving “plus equals” energy, but only when set 💅
