Re: [linux-usb-devel] [PATCH 0/6] Composite Gadget Support

The following series implements USB Composite Gadget Support.
[PATCH 1/6] USB gadget driver.
[PATCH 2/6] Composite gadget driver.
[PATCH 3/6] Composite gadget driver upgrade.
[PATCH 4/6] Kconfig modifications for USB Composite gadget support.
[PATCH 5/6] Composite File Storage gadget support.
[PATCH 6/6] Composite Ether gadget support.
The Composite Gadget can handle one or two configurations.
When the first usb_function modprobe'ed has two configurations
the Composite Gadget will have two configurations, for the
other functions modprobe'ed after will be used the selected or
standard configuration only, their interfaces will be part
of the Composite's Configurations.
Then exchanging configs in the Composite will only affect the
first function.
In case the first modprobe'ed function has only one configure,
the Composite Gadget WILL have only one configuration.
This behavior is useful when modprobe'ing g_ether as the first
usb_function due to the RNDIS and CDC Configurations.
How does this patchset differ from your earlier versions?
You has sent for me comments about ep0 complete function, see below:
---
From: Alan Stern
This looks a lot cleaner than your earlier attempts. However in
several places you took out code without adding any sort of
replacement. For example, here:
-static void ep0_complete(struct usb_ep *ep, struct usb_request *req)
-{
- struct fsg_dev *fsg = ep-driver_data;
-
- if (req-actual 0)
- dump_msg(fsg, fsg-ep0req_name, req-buf, req-actual);
- if (req-status || req-actual != req-length)
- DBG(fsg, %s -- %d, %u/%u\n, __FUNCTION__,
- req-status, req-actual, req-length);
- if (req-status == -ECONNRESET) // Request was cancelled
- usb_ep_fifo_flush(ep);
-
- if (req-status == 0 req-context)
- ((fsg_routine_t) (req-context))(fsg);
-}
Your modified driver doesn't call dump_msg(), DBG(), or the function
pointer stored in req-context.
---
Now for specific function request, use own ep0 complete function, e.g.
when it is TYPE_CLASS request.
When it is general request, e.g. DT_DEVICE request, use the
composite's ep0 complete.
I implemented dump_msg() function in the composite layer too.
