💖 imx_dsp_rproc_sys_to_da(9) 💖

okay bestie, welcome to the Kernel API Manual page for imx_dsp_rproc_sys_to_da — literally an internal memory translation helper, and we're gonna get into it ✨

🌸 NAME 🌸

imx_dsp_rproc_sys_to_da — internal memory translation helper 🎀

✨ SYNOPSIS ✨

int imx_dsp_rproc_sys_to_da (struct imx_dsp_rproc *priv , u64 sys ,
       size_t len , u64 *da );

🎀 ARGUMENTS 🎀

• priv — private data pointer 💅
• sys — system address (DDR address)
• len — length of the memory buffer
• da — device address to translate 🦋

🦋 DESCRIPTION 🦋

okay so this helper converts a system address (DDR address) to a device address (DSP), because there may be a memory remap for the device. that's the whole vibe, no cap 💖
