Subject: [RFC PATCH 0/6] cxl: Add support for CXL feature commands, CXL device patrol scrub control and DDR5 ECS control features
Date: Tue, 14 Nov 2023 20:56:41 +0800 [thread overview]
Message-ID: <20231114125648.1146-1-shiju.jose@huawei.com> (raw)
From: Shiju Jose <shiju.jose@huawei.com>
1. Add support for CXL feature commands(CXL spec 3.0 section 8.2.9.6).
2. Add CXL device scrub driver supporting patrol scrub control feature
(CXL spec 3.1 section 8.2.9.9.11.1) and DDR5 ECS feature(CXL spec 3.1
section 8.2.9.9.11.2).
3. Add scrub attributes for DDR5 ECS control to the memory scrub driver.
The attributes for the CXL scrub control features is exposed to the user
in the sysfs and is based on the previous code submitted for the memory
scrub control feature.
The patch and series for supporting memory scrub control feature are here,
