Subject: [PATCH v3 4/4] hw/nvme: Expand VI/VQ resource to uint32
Date: Wed, 8 May 2024 21:31:07 +0900 [thread overview]
Message-ID: <20240508123107.87919-5-minwoo.im.dev@gmail.com> (raw)
In-Reply-To: <20240508123107.87919-1-minwoo.im.dev@gmail.com>
From: Minwoo Im <minwoo.im@samsung.com>
VI and VQ resources cover queue resources in each VFs in SR-IOV.
Current maximum I/O queue pair size is 0xffff, we can expand them to
cover the full number of I/O queue pairs.
This patch also fixed Identify Secondary Controller List overflow due to
expand of number of secondary controllers.
