bcm63xx_ep0_...rnal_request(9)

💅 bcm63xx_ep0_internal_request(9) 💅

Okay so this page is straight out of the Kernel API Manual, and today's main character is bcm63xx_ep0_internal_request(9). Bestie, it's a helper function for submitting an ep0 request — support-function excellence, honestly. ✨

🌸 NAME 🌸

bcm63xx_ep0_internal_request — helper function to submit an ep0 request. 💅

✨ SYNOPSIS ✨

The signature is giving exactly this:

void bcm63xx_ep0_internal_request (struct bcm63xx_udc *udc , int ch_idx , int length );

🎀 ARGUMENTS 🎀

Three args, no mystery:

• udc — reference to the device controller. Controller reference secured. 🫶
• ch_idx — IUDMA channel number. Channel-index moment. 🦋
• length — number of bytes to TX/RX. Bytes to TX/RX, periodt. 💫

🦋 DESCRIPTION 🦋

This is the helper used for the simple transfers performed by the ep0 worker. It will always use ep0_ctrl_req / ep0_ctrl_buf — no cap. 💖
