Subject: [dpdk-dev] [PATCH v4 04/27] common/octeontx2: add mailbox base support infra
Date: Sat, 22 Jun 2019 18:53:54 +0530 [thread overview]
Message-ID: <20190622132417.32694-5-jerinj@marvell.com> (raw)
In-Reply-To: <20190622132417.32694-1-jerinj@marvell.com>
From: Jerin Jacob <jerinj@marvell.com>
This patch adds mailbox init and fini support.
Each RVU device has a dedicated 64KB mailbox region
shared with its peer for communication. RVU AF has
a separate mailbox region shared with each of RVU PFs
and an RVU PF has a separate region shared with
each of it's VF.
