Paul Mackerras [Mon, 30 Apr 2007 03:03:39 +0000]
[POWERPC] Remove dev_dbg redefinition in drivers/ps3/vuart.c

Commit 404d5b185b4eb56d6fa2f7bd27833f8df1c38ce4 changed the definition
of dev_dbg in the !DEBUG case from being a #define to being a static
inline.  There was code in drivers/ps3/vuart.c to do exactly that,
which fails to compile now.  This fixes it by removing the redefinition,
as the redefinition is now superfluous.

Len Brown considers that an active by default fan control interface in

chance he is quite correct on this, especially if someone decides to use

This patch adds a master switch to thinkpad-acpi that enables or disables
the entire fan-control feature as a module parameter: "fan_control".  It
defaults to disabled.  Set it to non-zero to enable fan control.

Also, the patch removes the expermiental status from fan control, since it
is stable enough to not be called experimental, and the master switch makes
it safe enough to do so.

ACPICA: clear fields reserved before FADT r3

Linux-2.6.21 stopped booting on a P4/HT because Linux
wrote the FADT.CST_CNT value to the SMI_CMD.
Apparently this stumbled over some SMM instability,
such as confusing SMM when invoking it from cpu1.

Linux did this because even though the r2 FADT reserves
the CST_CNT field, this BIOS set that field and Linux
used it.

Turns out that up through 2.6.20 we explicitly cleared
cst_control for r2 FADTs.  So here we go back to doing that,
plus also clear some additional fields that are reserved
until FADT r3.

libata: Handle drives that require a spin-up command before first access

(S)ATA drives can be configured for "power-up in standby",
a mode whereby a specific "spin up now!" command is required
before the first media access.

Currently, a drive with this feature enabled can not be used at all
with libata, and once in this mode, the drive becomes a doorstop.

The older drivers/ide subsystem at least enumerates the drive,
so that it can be woken up after the fact from a userspace HDIO_*
command, but not libata.

This patch adds support to libata for the "power-up in standby"
mode where a "spin up now!" command (SET_FEATURES) is needed.
With this, libata will recognize such drives, spin them up,
and then re-IDENTIFY them if necessary to get a full/complete
set of drive features data.

Drives in this state are determined by looking for
special values in id[2], as documented in the current ATA specs.

libata: convert legacy PCI host handling to new init model

Convert legacy PCI host handling to alloc-init-register model.
ata_init_legacy_host(), ata_request_legacy_irqs() and
ata_pci_init_bmdma() are separated out and follow the new init model.

The two legacy handling functions use separate ata_legacy_devres
instead of generic devm_* resources.  This reduces devres overhead for
legacy hosts which was a bit high because it didn't use PCI/iomap
merged resoruces.

ata_pci_init_one() is rewritten in terms of the aboved functions but
native mode handling is still using the old method.  Conversion will
be completed when native mode handling is updated.

Reorganize ata_host_alloc() and its subroutines into the following
three functions.

* ata_host_alloc() : allocates host and its ports.  shost is not

* ata_scsi_add_hosts() : allocates and adds shosts associated with an

* ata_host_register() : takes a fully initialized ata_host structure
  and registers it to libata layer and probes it.

Only ata_host_alloc() and ata_host_register() are exported.
ata_device_add() is rewritten using the above functions.  This patch
does not introduce any observable behavior change.  Things worth

  ata_host_register() will throw away unused ports automatically.

Tejun Heo [Tue, 20 Mar 2007 06:24:11 +0000]
libata: improve AC_ERR_DEV handling for ->post_internal_cmd

->post_internal_cmd is simplified EH for internal commands.  Its
primary mission is to stop the controller such that no rogue memory
access or other activities occur after the internal command is
released.  It may provide error diagnostics by setting qc->err_mask
but this hasn't been a requirement.

To ignore SETXFER failure for CFA devices, libata needs to know
whether a command was failed by the device or for any other reason.
ie. internal command needs to get AC_ERR_DEV right.

This patch makes the following changes to AC_ERR_DEV handling and
->post_internal_cmd semantics to accomodate this need and simplify
callback implementation.

1. As long as the correct bits in the result TF registers are set,
   there is no need to set AC_ERR_DEV explicitly.  libata EH core
   takes care of that for both normal and internal commands.

2. The only requirement for ->post_internal_cmd() is to put the
   controller into quiescent state.  It needs not to set any err_mask.

3. ata_exec_internal_sg() performs minimal error analysis such that
   AC_ERR_DEV is automatically set as long as result_tf is filled
   correctly.

Tejun Heo [Sun, 18 Mar 2007 13:15:33 +0000]
ahci: implement ata_save/restore_initial_config()

There are several registers which describe how the controller is
configured.  These registers are sometimes implemented as r/w
registers which are configured by firmware and get cleared on
controller reset or after suspend/resume cycle.  ahci saved and
restored those values inside ahci_reset_controller() which is a bit
messy and doesn't work over suspend/resume cycle.

This patch implements ahci_save/restore_initial_config().  The save
function is called during driver initialization and saves cap and
port_map to hpriv.  The restore function is called after the
controller is reset to restore the initial values.

Sometimes the initial firmware values are inconsistent and need to be
fixed up.  This is handled by ahci_save_initial_config().  For this,
there are two versions of saved registers.  One to write back to the
hardware register, the other to use during driver operation.  This is
necessary to keep ahci's behavior unchanged (write back fixed up
port_map while keeping cap as-is).

This patch makes ahci save the register values once before the first
controller reset, not after it's been reset.  Also, the same stored
values are used written back after each reset, so the register values
are properly recovered after suspend/resume cycle.
