Add a new interface for userspace to preallocate memory that can be
used with usbfs. This gives two primary benefits:
- Zerocopy; data no longer needs to be copied between the userspace
and the kernel, but can instead be read directly by the driver from
userspace's buffers. This works for a

According to DWC2 documentation, DPTxFSize field of DPTXFSIZn register
is read only, which means that software cannot change FIFO size.
Register description says:
"The value of this register is the Largest Device Mode Periodic Tx Data

Since FIFO is always freed in dwc2_hsotg_ep_disable(), ep->fifo_index
is always 0 in dwc2_hsotg_ep_enable(), hence code inside if() block is
never executed.

Since we handle FIFOs and endpoint separately, using variable named 'ep'
in context of FIFO is misleading, hence we rename it to 'fifo'.

As kill_all_requests() potentially flushes TX FIFO, we should should
free FIFO after calling it. Otherwise FIFO could stay unflushed properly.

Hello,
This patch series fixes TX FIFO handling in UDC part of DWC2 driver.
It gets rid of few bugs, improves compliance with DWC2 documentation
and cleanes up driver code. More detailed description is provided in
commit messages.
Best regards,
Robert Baldyga

Hi Mathias,
I re-tried if this issue exists with linux-4.4-rc7 and I reproduced it.
Actually, with ASM-based USB3-to-SATA dongle instead of the one with Prolific

Hi Peter,

In the dtsi for the MX23 the usb node has the following compatible:

In current acm driver, the bulk-in callback function ignores the
URBs unlinked in usb core.
This causes unexpected data loss in some cases. For example,
runtime suspend entry will unlinked all urbs and set urb->status
to -ENOENT even those urbs might have data not processed yet.
Hence, data loss o
