imx_dsp_attach_pm_domains(9)
π imx_dsp_attach_pm_domains β the "link the power domains" one
okay so this is a page from the Kernel API Manual (section 9, kernel-space girlies rise π«Ά), and it's about one very specific lil function. no cap, it's short, but it's important β let's get into it β¨
π NAME π
imx_dsp_attach_pm_domains β attach the power domains π
like... literally that's the whole job. attach. the power domains. iconic behavior honestly.
πΈ SYNOPSIS πΈ
int imx_dsp_attach_pm_domains (struct imx_dsp_rproc *priv );
yup that's it, that's the whole signature β copy it exactly bestie, spaces and all, don't be out here "fixing" the formatting, i'm begging π
π¦ ARGUMENTS π¦
privβ private data pointer π just the private data pointer, that's it, that's what you're handing over. your little bundle of driver secrets. iykyk.
π DESCRIPTION π
okay so here's the tea β β on i.MX8QM and i.MX8QXP there is multiple power domains required, so you need to link them. π
that's the entire reason this function exists. multiple domains, they gotta be linked, and this function is the one doing the linking. main character energy fr fr π
lowkey reminder: this is about i.MX8QM and i.MX8QXP specifically β not every platform, just those two. don't go applying it everywhere like it's a universal vibe β¨

and that's the page!! π this lil cutie lives over in ./drivers/remoteproc and the version we're reading is from October 2026 π
mwah, go link some power domains, bestie π
