* usb gadget: function activation/deactivationDavid Brownell2008-10-171-0/+64
| | | | | | | | | | | | | | | | Add a new mechanism to the composite gadget framework, letting functions deactivate (and reactivate) themselves. Think of it as a refcounted wrapper for the software pullup control. A key example of why to use this mechanism involves functions that require a userspace daemon. Those functions shuld use this new mechanism to prevent the gadget from enumerating until those daemons are activated. Without this mechanism, hosts would see devices that malfunction until the relevant daemons start.

* usb gadget: issue notifications from ACM functionDavid Brownell2008-08-133-27/+235
| | | | | | | | | | | | | | | | | Update the CDC-ACM gadget code to support the peripheral-to-host notifications when the tty is opened or closed, or issues a BREAK. The serial framework code calls new generic hooks; right now only CDC-ACM uses those hooks. This resolves several REVISIT comments in the code. (Based on a patch from Felipe Balbi.) Note that this doesn't expose USB_CDC_CAP_BRK to the host, since this code still rejects USB_CDC_REQ_SEND_BREAK control requests for host-to-peripheral BREAK signaling (received via /dev/ttyGS*).

* USB: serial gadget: rx path data loss fixesDavid Brownell2008-08-131-90/+146
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Update RX path handling in new serial gadget code to cope better with RX blockage: queue every RX packet until its contents can safely be passed up to the ldisc. Most of the RX path work is now done in the RX tasklet, instead of just the final "push to ldisc" step. This addresses some cases of data loss: - A longstanding serial gadget bug: when tty_insert_flip_string() didn't copy the entire buffer, the rest of the characters were dropped! Now that packet stays queued until the rest of its data is pushed to the ldisc. - Another longstanding issue: in the unlikely case that an RX transfer returns data and also reports a fault, that data is no longer discarded. - In the recently added RX throttling logic: it needs to stop pushing data into the TTY layer, instead of just not submitting new USB read requests. When the TTY is throttled long enough, backpressure will eventually make the OUT endpoint NAK. Also: an #ifdef is removed (no longer necessary); and start switching to a better convention for debug messages (prefix them with tty name).

As seen with the other gadget driver conversions, the resulting code is much easier to understand and (presumably) work with. In this case that's especially true, since the Ethernet gadget had grown to handle three (!) different Ethernet-over-USB protocols. This modularization should make it much easier to add a fourth option for the newish CDC "Ethernet Emulation Model" (or EEM). Lightly tested, primarily at full speed.

* | | | usb ethernet gadget: split out network coreDavid Brownell2008-07-213-1/+1051
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Abstract the peripheral side Ethernet-over-USB link layer code from the all-in-one Ethernet gadget driver into a component that can be called by various functions, so the various flavors can be split apart and selectively reused. A notable difference from the approach taken with the serial link layer code (beyond talking to NET not TTY) is that because of the initialization requirements, this only supports one network link. (And one set of Ethernet link addresses.) That is, each configuration may have only one instance of a network function. This doesn't change behavior; the current code has that same restriction. If you want multiple logical links, that can easily be done using network layer tools.

* | | | usb gadget: RNDIS cleanupsDavid Brownell2008-07-214-328/+79

There's a separate method to stop using the link. (Bug doesn't affect anything right now because of how the code is used.) - Reduce coupling between RNDIS code and its user(s), in preparation for updates in that code: * Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device by passing just a void* handle. (Also, remove the unused return value of the notification callback.) * When it needs a copy of net_device stats, just ask for it - Remove unused/untested code backing various never-used OIDs: * RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the relevant docs were unclear, ambguous, and incomplete. Someone with access to the Hidden Gospels (maybe in the EU?) might be able to figure out what this should do. * RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never implemented in part because not all the semantics were clear. * OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever. - A few small whitespace fixes Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style. There should be no functional changes because of this patch; it's a net source code shrink (because of the dead/unused code removal) and a small object code shrink (a couple hundred bytes on ARMv5).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Split out the generic serial support into a "function driver". This closely mimics the ACM support, but with a MUCH simpler control model. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Some key structural differences from the previous ACM support, shared with with the generic serial function (next patch): - As a function driver, it can be combined with other functions. One gadget configuration could offer both serial and network links, as an example. - One serial port can be exposed in multiple configurations; the /dev/ttyGS0 node could be exposed regardless of which config the host selected. - One configuration can expose multiple serial ports, such as ttyGS0, ttyGS1, ttyGS2, and ttyGS3. This code should be a lot easier to understand than the previous all-in-one-big-file version of the driver.
