hisi_qm_put_dfx_access(9)

💖 NAME

Okay bestie, this is the hisi_qm_put_dfx_access(9) page from the Kernel API Manual — and it’s a short one, thank god. The function is hisi_qm_put_dfx_access, and its whole job is: put dfx access. Slay.

✨ SYNOPSIS

void hisi_qm_put_dfx_access (struct hisi_qm *qm );

🎀 ARGUMENTS

• qm — pointer to accelerator device. That’s it, that’s the argument. Main character energy fr.

🦋 DESCRIPTION

Okay so the description is giving minimalism: this puts the dfx access and drops the runtime PM usage counter. No cap, that’s the whole function. It’s void in the synopsis, so there’s no return value to obsess over.
