* b43: Kconfig: drop unknown symbol 'BRCMSMAC_MODULE'Paul Bolle2012-09-01
| | | | | | | | | | | | There's no Kconfig symbol BRCMSMAC_MODULE, so the check for it will always fail. There's no need to append _MODULE to tristate symbols anyhow, because the config tools will do the right thing automagically. (While we're touching this Kconfig file replace a tab between "default" and "y" with a space.) Signed-off-by: Paul Bolle <pebolle@tiscali.nl> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

'data' is being allocated by devm_kzalloc(), is it's actually wrong to free() it in the error path, as it will be destroyed properly later.

| | * | | HID: uhid: implement feature requestsDavid Herrmann2012-06-18

If it doesn't do this in a timely manner, the request is discarded silently. We serialize the feature requests, that is, there is always only a single active feature-request sent to user-space, other requests have to wait. HIDP and USB-HID do it the same way. Because we discard feature-requests silently, we must make sure to match a response to the corresponding request. We use sequence-IDs for this so user-space must copy the ID from the request into the answer. Feature-answers are ignored if they do not contain the same ID as the currently pending feature request. Internally, we must make sure that feature-requests are synchronized with UHID_DESTROY and close() events. We must not dead-lock when closing the HID device, either, so we have to use separate locks.

We now forward these requests directly to user-space so the transport-level driver can correctly send it to the device or handle it correspondingly. There is no way to signal back whether the transmission was successful, moreover, there might be lots of messages coming out from the driver flushing the output-queue. However, there is currently no driver that causes this so we are safe. If some drivers need to transmit lots of data this way, we need a method to synchronize this and can implement another UHID_OUTPUT_SYNC event.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | HID core notifies us with *_open/*_close callbacks when there is an actual user of our device. We forward these to user-space so they can react on this. This allows user-space to skip I/O unless they receive an OPEN event. When they receive a CLOSE event they can stop I/O again to save energy.

We copy the data into kernel memory and directly feed it into the HID core. There is no error handling of the events couldn't be parsed so user-space should consider all events successfull unless read() returns an error.

This allows us to extend the event structure and still keep backwards compatibility. If user-space wants to get multiple events in one syscall, they should use the readv()/writev() syscalls which are supported by uhid. This introduces a new lock which helps us synchronizing simultaneous reads from user-space. We also correctly return -EINVAL/-EFAULT only on errors and retry the read() when some other thread captured the event faster than we did.

However, this doesn't matter here as user-space would need to poll() in two threads simultaneously to trigger this. And in this case it doesn't matter if a cached result is returned or the exact new result as user-space does not know which thread returns first from poll() and the following read(). So it is safe to compare the values without locking. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

This adds a static buffer for 32 messages to each uhid device. Each message is dynamically allocated so the uhid_device structure does not get too big. uhid_queue() adds a message to the buffer. If the buffer is full, the message is discarded. uhid_queue_event() is an helper for messages without payload. This also adds a public header: uhid.h. It contains the declarations for the user-space API. It is built around "struct uhid_event" which contains a type field which specifies the event type and each event can then add a variable-length payload. For now, there is only a dummy event but later patches will add new event types and payloads. Signed-off-by: David Herrmann <dh.herrmann@googlemail.com> Signed-off-by: Jiri Kosina <jkosina@suse.cz>

This allows to write transport-level drivers like USB-HID and Bluetooth-HID in user-space. Low-Energy Bluetooth needs this to feed HID data that is parsed in user-space back into the kernel.

Hence, if a driver uses the raw_event callback but no other listener claimed the device, we still leave it on the bus as the driver handles everything by itself. It thus becomes its own listener. Under some circumstances (eg., hidinput_connect() fails and raw_event set) a device may be left on the bus even though it requires external listeners. But then if hidinput_connect() fails there are bigger issues than a device that is left unhandled. So we can safely use this heuristic to avoid adding another flag for special devices like hid-picolcd and hid-wiimote. This also removes the ugly hack from hid-picolcd as this is no longer required.

The driver was not careful to restart everything that might have been stopped, in cases where a suspend failed. For example, once the HID_SUSPENDED flag is set, an output report submission would not restart the corresponding URB queue. If a suspend fails, it's therefore necessary to check whether the queues need to be restarted.
