Some protocols implemented in userspace with FunctionFS might require large
buffers, e.g. 64kB or more. Currently the said memory is allocated with
kmalloc, which might fail should system memory be highly fragmented.
On the other hand, some UDC hardware allows scatter-gather operation and

Hi John,
Sorry re-sending as it was detected as spam before (due to HTML subpart).
I’m not certain if you are the correct person that maintains the
drivers/usb/dwc2 for Linux kernel 4.14. I noticed that 4.20 is a different
person.
We are using an Altera Cyclone V SoC FPGA on our board with lin

However, it's conceivable that some UDC drivers might behave
differently depending on whether the usb_ep_queue call occurs within
the setup callb

The QCA Rome USB Bluetooth controller has several issues once LPM gets
enabled:
- Fails to get enumerated in coldboot. [1]
- Drains more power (~ 0.2W) when the system is in S5. [2]
- Disappears after a warmboot. [2]
The issue happens because the device lingers at LPM L1 in S5, so device
can't get
