    Subject[PATCH v3 09/17] xen/hvm/params: Add a new delivery type for event-channel in HVM_PARAM_CALLBACK_IRQ
    Date
    From: Shannon Zhao <shannon.zhao@linaro.org>

    Add a new delivery type:
    val[63:56] == 3: val[15:8] is flag: val[7:0] is a PPI.
    To the flag, bit 0 stands the interrupt mode is edge(1) or level(0) and
    bit 1 stands the interrupt polarity is active low(1) or high(0).
