💅 cs_dsp_read_raw_data_block — Kernel API Manual energy ✨

okay bestie, so this is a Kernel API Manual page, and it's all about cs_dsp_read_raw_data_block — the little function that literally grabs a whole block of data out of DSP memory for you. no cap, it's giving "fetch" in the most technical way possible 🎀

🌸 NAME 🌸

cs_dsp_read_raw_data_block — reads a block of data from DSP memory</p> 💖

✨ SYNOPSIS ✨

int cs_dsp_read_raw_data_block (struct cs_dsp *dsp , int mem_type ,
unsigned int mem_addr , unsigned int num_words , __be32 *data );

🫶 ARGUMENTS 🫶

  • dsp — pointer to DSP structure. yeah she's the main character, everything runs through her 👑
  • mem_type — the type of DSP memory containing the data to be read. like, which memory vibe are we in 🦋
  • mem_addr — the address of the data within the memory region. the lil map pin for where your data lives 📍
  • num_words — the length of the data to read. how many words we're snatching 💅
  • data — a buffer to store the fetched data. the basket you're carrying it all home in 🧺

💜 DESCRIPTION 💜

so here's the tea 🍓 — if you use this to read unpacked 24-bit memory, each 24-bit DSP word will occupy 32-bits in data, and the MSbyte will be 0. that's the padding, bestie, it's just chillin' there 🙈

if you don't want that extra padding hanging around, you can remove it with cs_dsp_remove_padding ✨

🔥 RETURN 🔥

Zero for success 🎉 … or a negative number on error 😭 (we don't love that for us, but ok).
