💅 cs_dsp_mock_reg_block_length_registers — Kernel API Manual (9)

okay so bestie, buckle up, we're in the Kernel API Manual today and this one's a lil function from ./drivers/firmware/cirrus/test and honestly? it's giving "small but mighty." let's get into it 🫶

✨ NAME ✨

cs_dsp_mock_reg_block_length_registers — literally just tells you the number of registers in an access block. that's it. that's the whole job. iconic behavior tbh 🎀

🌸 SYNOPSIS 🌸

unsigned int cs_dsp_mock_reg_block_length_registers (struct cs_dsp_test
*priv , int mem_type );

like, she's an unsigned int returning girlie and she takes two args. no cap. ✨

🦋 ARGUMENTS 🦋

  • priv — a pointer to struct cs_dsp_test. yes bestie, the whole struct. she needs it. 💖
  • mem_type — the memory region type. which region are we talking about? this is how you tell her. 🧚

👑 RETURN 👑

she returns the total number of registers forming the smallest bus access size 💫 and here's the tea on how that breaks down:

  • for unpacked memory 👉 it's the number of registers containing one DSP word
  • for packed memory 👉 it's the number of registers in one packed access block

so like, same function, two vibes depending on your memory type. lowkey elegant ngl 💅

ok that's the whole page bestie, go touch some registers 💀✨

mwah 💋 this lil cutie lives in ./drivers/firmware/cirrus/test, dated October 2026, in the Kernel API Manual — and the title up top got a lil abbreviated as cs_dsp_mock_...th_registers(9) but you knew that already, iykyk 🌈💜
