dwc2_flush_rx_fifo(9)

💅 dwc2_flush_rx_fifo(9) — from the Kernel API Manual, bestie ✨

Okay so picture this: it's a kernel API manual page, the vibes are immaculate, and the function is dwc2_flush_rx_fifo. That's the main character. We're in dwc2_flush_rx_fifo(9) territory and it's giving "small function, big responsibility." Let's get into it 🫶

---

🌸 NAME 🌸

dwc2_flush_rx_fifo — literally flushes the Rx FIFO. That's it. That's the whole job. No cap 💅

---

✨ SYNOPSIS ✨

void dwc2_flush_rx_fifo (struct dwc2_hsotg *hsotg );

Returns nothing (it's void, she's humble like that), takes exactly one argument, and gets straight to business. Iconic behavior honestly 🎀

---

🦋 ARGUMENTS 🦋

• hsotg — the programming view of the DWC_otg controller, aka the whole entire controller situation in one struct pointer. Hand her over and she knows what to do 💖

🔥 SEE ALSO 🔥

Bestie, the friend group is large and every single one of them is invited. This page lives in the kernel file ./drivers/usb/dwc2/core.c, and it's adjacent to all of these:

• dwc2_backup_global_registers(9)
• dwc2_restore_global_registers(9)
• dwc2_exit_partial_power_down(9)
• dwc2_enter_partial_power_down(9)
• dwc2_restore_essential_regs(9)
• dwc2_hib_restore_common(9)
• dwc2_wait_for_mode(9)
• dwc2_iddig_filter_enabled(9)
• dwc2_force_mode(9)
• dwc2_clear_force_mode(9)
• dwc2_dump_host_registers(9)

• dwc2_disable_global_interrupts(9)
• dwc2_hsotg_wait_bit_set(9)
• dwc2_hsotg_wait_bit_clear(9)

Notice dwc2_flush_tx_fifo(9) sitting right there next to her? That's her sibling. Rx and Tx. Flush twins. We stan a balanced FIFO household 🙈

🌈 And that's the whole page, bestie — short, sweet, and to the point, which honestly is a mood. This little icon dropped in ./drivers/usb/dwc2 land back in October 2026, and she's been slaying ever since. Go read the other dwc2_* pages, ily, bye 💜👑
