From e829ea9a5ea05c6dedd91f741f91cb8723e50b19 Mon Sep 17 00:00:00 2001 From: Solomon Peachy Date: Wed, 23 Oct 2024 14:16:15 -0400 Subject: ata: Rework how flushing, sleeping, and power off interacts * FLUSH_EXT is used if featureflag is set and we are using LBA48 (unconditionally used for CE-ATA on ipod6g) * FLUSH is used if featureflag is set (ATA6+) or if device claims to be ATA5+ * Rename ata_disk_can_power_off() to ata_disk_can_sleep() as that is what it actually tests for. Only use it to gate issuing the STANDBY IMMEDIATE command. * Restore behavior of ata_disk_is_active() to return 1 if drive is "spinning" or powered up. * Allow poweroff if drive claims PM support OR we are able to issue FLUSH/FLUSH_EXT commands. * Added ata_flush() to explicitly trigger a flush operation, and hook it up to storage_flush() in the device shutdown path. (Flushes were only previously used in the storage device power management path) * After issuing all settings, re-issue IDENTIFY_DEVICE to make sure it reflects everything we've enabled. * Update manual section on Flash/SSD mods.
