    conf: Add a new xenbus controller option for event channels · 8e669b38
    Jim Fehlig 提交于
    Event channels are like PV interrupts and in conjuction with grant frames
    form a data transfer mechanism for PV drivers. They are also used for
    inter-processor interrupts. Guests with a large number of vcpus and/or
    many PV devices many need to increase the maximum default value of 1023.
    For this reason the native Xen config format supports the
    'max_event_channels' setting. See xl.cfg(5) man page for more details.
    
    Similar to the existing maxGrantFrames option, add a new xenbus controller
    option 'maxEventChannels', allowing to adjust the maximum value via libvirt.
