Subject: [PATCH v4 03/10] include/hw/cxl/cxl_device: Rename mem_size as static_mem_size for type3 memory devices
Date: Wed, 21 Feb 2024 10:15:56 -0800 [thread overview]
Message-ID: <20240221182020.1086096-4-nifan.cxl@gmail.com> (raw)
In-Reply-To: <20240221182020.1086096-1-nifan.cxl@gmail.com>
From: Fan Ni <fan.ni@samsung.com>
Rename mem_size as static_mem_size for type3 memdev to cover static RAM and
pmem capacity, preparing for the introduction of dynamic capacity to support
dynamic capacity devices.
Signed-off-by: Fan Ni <fan.ni@samsung.com>
