Subject: [PATCH 0/3] nvme: Add sysfs interface for APST configuration management
Date: Wed, 26 Mar 2025 17:57:56 +0800 [thread overview]
Message-ID: <tencent_FD614E97ED4F67FE2F74C9C158AB50E7C806@qq.com> (raw)
From: Yaxiong Tian <tianyaxiong@kylinos.cn>
This series enhances NVMe APST (Autonomous Power State Transition) support by:
1. Adding warnings for PST table allocation failures
2. Exposing APST tables via sysfs for runtime inspection
3. Providing per-controller sysfs interface for APST configuration
The changes allow better visibility and control of power management settings
through userspace tools while maintaining the existing functionality.
Yaxiong Tian (3):
nvme: Add warning for PST table memory allocation failure in
nvme_configure_apst
nvme: add sysfs interface for APST table updates
nvme: add per-controller sysfs interface for APST configuration
