[PATCH 0/3] nvme: Add sysfs interface for APST configuration management

[Yaxiong Tian]

From: Yaxiong Tian <tianyaxiong@xxxxxxxxxx>

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
