Several users of the signal API used custom convenience classes to invoke signal-handling functions on the reception of incoming signals. The 'Signal_dispatcher' pattern turned out to be particularly useful. To avoid the duplication of this code across the code base, this patch adds the interface to 'base/signal.h'. Furthermore, the patch changes the 'Signal::num()' return type from int to unsigned because negative numbers are meaningless here. Fixes #511
Device drivers ported from the Linux kernel USB ### HID ~~~ Supports keyboard and mouse. A run script can be found under 'run/usb_hid.run'. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="3M"/> ! <provides><service name="Input"/></provides> ! <config> ! <hid/> ! </config> !</start> Note: It has been observed that certain 1.0 versions of Qemu do not generate mouse interrupts. The mouse driver should work correctly on Qemu 1.0.93 and above. Storage ~~~~~~~ Currently supports one USB storage device. Hot plugging has not been tested. A run script can be found under 'run/usb_storage.run'. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="2M"/> ! <provides> <service name="Block"/> </provides> ! <config><storage /></config> !</start> Network (Nic) ~~~~~~~~~~~~~ Supported on PandaBoard only using the 'smsc95xx' driver. Configuration snippet: !<start name="usb_drv"> ! <resource name="RAM" quantum="3M"/> ! <provides> ! <service name="Nic"/> ! <service name="Input"/> ! </provides> ! <config> ! <nic mac="2e:60:90:0c:4e:01" /> ! <hid/> ! </config> !</start> Please observe that this setup starts the HID and Nic service at the same time. Also there is the 'mac' attribute where one can specify the hardware address of the network interface. This is necessary in case the EEPROM of the network card cannot be accessed via the host controller making it impossible to retrieve the devices hardware address. If this is the case and no 'mac' attribute is given a fallback address will be assigned to the network device. Note that the fallback address will always be the same.
