π cs_dsp_chunk_read(9) π
okay so bestie, welcome to the Kernel API Manual β this one's a little legend named cs_dsp_chunk_read, and it lives in ./drivers/firmware/cirrus. let me tell you everything, no cap β¨
β¨ NAME β¨
cs_dsp_chunk_read β parse data from a DSP memory chunk π
π¦ SYNOPSIS π¦
int cs_dsp_chunk_read (struct cs_dsp_chunk *ch , int nbits );
πΈ ARGUMENTS πΈ
chβ pointer to the chunk structure, she's the main character here πnbitsβ how many bits you wanna read, literally that many π’
π DESCRIPTION π
so this function sequentially reads values out of a DSP memory formatted buffer. and yes, she does the unglamorous work too β she handles both the removing of the padding bytes and the converting from big endian. the way that she multitasks?? iconic. π
β RETURN β
if it goes wrong you get a negative number back π. otherwise, it's the read value β slay π

and that's the whole page, bestie π§π this cutie came from ./drivers/firmware/cirrus and the docs are stamped October 2026 β go read some DSP memory, ily, bye ππ
