| H A D | libata-acpi.c | diff 19ccee765f8030c1e36720b6bcb7e8bd8262af5c Sat Apr 27 03:37:53 CEST 2013 Lv Zheng <lv.zheng@intel.com> ACPI/libata: Restore libata.noacpi support
This patch restores libata.noacpi support to libata-acpi.c.
There are broken optional control methods for ATA controller devices in the
real world. The libata.noacpi has been used for a long time as a
workaround to deal with issues caused by the broken ASL codes.
1. The "noacpi" option is introduced by the following commit:
commit 11ef697b37e3c85ce1ac21f7711babf1f5b12784
Date: Thu, 28 Sep 2006 11:29:01 -0700
Subject: libata: ACPI and _GTF support
2. The "noacpi" option is renamed to "libata_noacpi" by the following
commit:
commit d7d0dad62a641c156386288a747c1a2f6bb2e42d
Date: Wed, 28 Mar 2007 01:57:37 -0400
Subject: [libata] Disable ACPI by default; fix namespace problems
3. Some of its logics are changed over time - becomes relying on the
"acpi_handle" bound to the ATA devices since this commit:
commit fafbae87db88a73b166d3bc3294d209207f27056
Date: Tue, 15 May 2007 03:28:16 +0900
Subject: libata-acpi: implement ata_acpi_associate()
4. The option is deleted by the following commit:
commit 30dcf76acc695cbd2fa919e294670fe9552e16e7
Date: Mon, 25 Jun 2012 16:13:04 +0800
Subject: libata: migrate ACPI code over to new bindings
But the libata.noacpi setup is still left in the kernel without codes to
implement it. So the deletion introduces a regression to the Linux.
This patch disables ATA_ACPI support at runtime by stopping acpi binding
on the ATA devices to fix this regression.
This patch is tested by booting a SATA x86-64 kernel or a PATA x86 kernel
with or without "libata.noacpi=1" kernel command line argument.

_GTF is an acpi method that is used to reinitialize the drive. It returns
a task file containing ata commands that are sent back to the drive to restore
it to boot up defaults.
