Subject: [PATCH v5 19/22] hvm/params: Add a new delivery type for event-channel in HVM_PARAM_CALLBACK_IRQ
Date: Fri, 4 Mar 2016 14:15:49 +0800 [thread overview]
Message-ID: <1457072152-16128-20-git-send-email-zhaoshenglong@huawei.com> (raw)
In-Reply-To: <1457072152-16128-1-git-send-email-zhaoshenglong@huawei.com>
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 8 stands the interrupt mode is edge(1) or level(0) and
bit 9 stands the interrupt polarity is active low(1) or high(0).
