When checking dwc2 host channel interrupts, handle qh in

In some SoCs, dwc3 is implemented as a USB2.0 only

The dma_pool_destroy() function tests whether its argument is NULL
and then returns immediately. Thus the test around the calls is not needed.

Previously we needed to set the max_transfer_size to explicitly be 65535
because the old driver would detect that our hardware could support much
bigger transfers and then would try to do them. This wouldn't work
since the DMA alignment code couldn't support it.
Later in commit e8f8c14d9da7 ("usb
All other host controllers who want aligned buffers for DMA do it a
certain way. Let's do that too instead of working behind the USB core's
back. This makes our interrupt handler not take forever and also rips
out a lot of code, simplifying things a bunch.
This also has the side effect of removi
The old microframe scheduler was hard to follow and had some bugs in
it. Specifically, I made some code to visualize what was happening and
found:
Add W (280 us):
WW|WW| | | | | |
Add B (260 us):
WW|WW|BB|BB
This series now effectively has two purposes:
1. Speed up dwc2 interrupt latency.
2. Start fixing up the microframe scheduler.
...the two things were separate series in the past but they ended up
running into each other, so now they're combined.
To summarize what we have here:
1. usb: dwc2: rock
In commit 94dfd7edfd5c ("USB: HCD: support giveback of URB in tasklet
context") support was added to give back the URB in tasklet context.
Let's take advantage of this in dwc2.
This speeds up the dwc2 interrupt handler considerably.
Note that this requires the change ("usb: dwc2: host: Add a dela
We'd like to be able to use HCD_BH in order to speed up the dwc2 host
interrupt handler quite a bit. However, according to the kernel doc for
usb_submit_urb() (specifically the part about "Reserved Bandwidth
Transfers"), we need to keep a reservation active as long as a device
driver keeps submitt
Until we have logic to determine which devices share the same TT let's
add logic to assume that all devices on a given dwc2 controller are on
one single_tt hub. This is better than the previous code that assumed
that all devices were on one multi_tt hub, since single_tt hubs
appear (in my experien
In preparation for future changes to the scheduler let's add some
tracing that makes it easy for us to see what's happening. By default
this tracing will be off.
Note that I've chosen to point tracing at ftrace rather than the console
since performance is pretty critical for these traces and ftra
The microframe scheduler did a lot of work to pick the proper
microframe. Then dwc2_sched_periodic_split() went ahead and ignored
which microframe we picked if it ever needed to re-assign things.
Let's keep track of the uframe and then we'll always use it.
