*wmfw_firmware , const char *wmfw_filename , const struct firmware
*coeff_firmware , const char *coeff_filename , const char *fw_name );

🦋 ARGUMENTS 🦋

six args, all main character energy, let's meet them 🫶

  • dsp — pointer to the DSP structure. this is your girl, the whole struct cs_dsp she's the moment 👑

  • wmfw_filename — file name of firmware to be sent. like a name tag for the firmware, so cute 🏷️
  • coeff_firmware — the coefficient data to be sent. the coefficients are coming along too, they're a package deal 💫
  • coeff_filename — file name of coefficient to data be sent. yes, that's exactly how the original says it, I'm not editing it, periodt 🎀
  • fw_name — the user-friendly firmware name. the cute display name, the one you'd put in your bio 🌈

and now the whole friend group, every single one, no one left out 💜:

ok real talk for one sec — the return value is the only "did it work" signal here, so like, check it. no peeking away, bestie 🙈

and that's the page!! mwah 💋 this lil number lives in ./drivers/firmware/cirrus, dated October 2026, and it's the cs_dsp_adsp1_power_up(9) page, so go forth and power up that firmware ✨🦋💖 slay responsibly 🌈👑
