Subject: [PATCH v2 0/3] ahci: fix boot/resume COMRESET failures
Date: Tue, 21 Feb 2012 10:38:41 -0800	[thread overview]
Message-ID: <1329849524-23758-1-git-send-email-computersforpeace@gmail.com> (raw)

This series addresses regression problems with

    commit 7faa33da9b7add01db9f1ad92c6a5d9145e940a7
    ahci: start engine only during soft/hard resets

Because the fix provided by the above commit caused COMRESET failures and
10 second boot-time/resume-time hangs for certain DVD drives, we need to
make the fix conditional to certain devices/platforms. Add a flag for this.

Brian

v2: change flag name to AHCI_HFLAG_DELAY_ENGINE, write more detailed
    comments

v1: flag named AHCI_HFLAG_STRICT_SPEC

Brian Norris (3):
  ahci: add AHCI_HFLAG_DELAY_ENGINE host flag
  ahci: move AHCI_HFLAGS() macro to ahci.h
  ahci_platform: add STRICT_AHCI platform type
