2014-03-24usb-linux: massive read perf improvement with 3 parallel transfersGravatar Mikkel Kamstrup Erlandsen1-34/+73
By maintaining 3 parallel usb trasfers when reading we get 2-3x more throughput when reading. Without this the usb port is mostly just idling. I get 23mb/s on my system compared to a clean Apple stack that gives me 17mb/s. 3 was chosen because it is simple to hard code, gives very good performance, and have very little impact on out resource consumption.

2014-03-24device: more aggresively send ACKs when receiving TCP dataGravatar Mikkel Kamstrup Erlandsen1-49/+66
Before this it seemed that we only ever sent ACK when timing out... Looks like a perf double when reading.

2014-01-09device/client: make device_get_list() allocate the result buffer itselfGravatar Nikias Bassen3-25/+26
Using device_get_count() and device_get_list() separately can return different device counts in case there are devices added to the list inbetween these two function calls. To prevent this, device_get_list() will allocate the buffer by itself.

2013-12-27preflight: replace idevice_event_* with thread safe implementationGravatar Nikias Bassen4-12/+31
idevice_event_subscribe() calls usbmuxd_subscribe() which will start a thread waiting for device add/remove events. But this implementation is not able to handle more than one "subscription". However the preflight worker will start a thread for _each_ device resulting in a really messed up situation if more than one device is attached at the same time. This fix will use usbmuxd's internal device_remove function calling a preflight callback to make this implementation thread safe.
2013-12-23increase number of open file descriptorsGravatar Nikias Bassen1-0/+7
When a large number of devices are used, the number of open file descriptors can reach the default system limit. Upon startup we now raise it to a much higher value to give more 'space'.

2013-11-04preflight: Make device visible during trust dialog pairing and handle unplugGravatar Martin Szulecki1-5/+27
The usbmuxd implementation on Win/OS X does allow enumerating and accessing the device during the "trust dialog" pairing process. We now also exit the waiting loop during unplugging of a device while waiting for the trust dialog to be dismissed.

2013-11-04udev: Set "deactivated" USB configuration on iOS devices by defaultGravatar Martin Szulecki1-2/+2
With the introduction of iOS 7, devices should start of in the "deactivated" USB configuration "0" by default to not trigger a trust dialog. Once the devices are identified, usbmuxd will set the correct USB configuration itself and immediately run the preflight worker code to ensure a trust relationship with the host is established. This change fixes the trust dialog from appearing during hotplug of paired devices. The last remaining issue is that current kernel code still sets the USB configuration to "1" by default before the udev rules and thus causes multiple connection beeps.

2013-09-26udev: lower rules numbering to make sure we start as early as possibleGravatar Nikias Bassen2-1/+1
To prevent the trust dialog from appearing on iOS7 devices we need to make sure that no PTP access is happening before usbmuxd starts. So we start as early as possible so the device will be in trusted host state.
