From 73ae7e1c7644a8c33ba526302a10267cdbc249f8 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Thu, 11 Jan 2024 17:57:44 +0100 Subject: ata: libata-sata: improve sysfs description for ATA_LPM_UNKNOWN Currently, both ATA_LPM_UNKNOWN (0) and ATA_LPM_MAX_POWER (1) displays as "max_performance" in sysfs. This is quite misleading as they are not the same. For ATA_LPM_UNKNOWN, ata_eh_set_lpm() will not be called at all, leaving the configuration in unknown state. For ATA_LPM_MAX_POWER, ata_eh_set_lpm() is called, and setting the policy to ATA_LPM_MAX_POWER. This also matches the description of the SATA_MOBILE_LPM_POLICY Kconfig: 0 => Keep firmware settings 1 => Maximum performance Thus, update the sysfs description for ATA_LPM_UNKNOWN to match reality. While at it, update libata.h to mention that the ascii descriptions are in libata-sata.c and not in libata-scsi.c.
