[PATCH] sata_nv: fix ATAPI in ADMA mode

The attached patch against 2.6.19-rc6-mm1 fixes some problems in sata_nv
with ATAPI devices on controllers running in ADMA mode. Some of the
logic in the nv_adma_bmdma_* functions was inverted causing a bunch of
warnings and caused those functions not to work properly. Also, when an
ATAPI device is connected, we need to use the legacy DMA engine. The
code now disables the PCI configuration register bits for ADMA so that
this works, and ensures that no ATAPI DMA commands go through until this
is done.

[PATCH] sata_promise fixes and updates

This patch updates the sata_promise driver as follows:
- Correct typo in definition of PDC_TBG_MODE: it's at 0x41C not 0x41
  in first-generation chips. This error caused PCI access alignment
  exceptions on SPARC64, and on all platforms it disabled the expected
  initialisation of TBG mode.
- Add flags field to struct pdc_host_priv. Define PDC_FLAG_GEN_II
  and use it to distinguish first- and second-generation chips.
- Prevent the FLASH_CTL FIFO_SHD bit from being set to 1 on second-
  generation chips. This matches Promises' ulsata2 driver.
- Prevent TBG mode and SLEW rate initialisation in second-generation chips.
  These two registers have moved, TBG mode has been redefined, and
  Promise's ulsata2 driver no longer attempts to initialise them.
- Correct PCI device table so devices 0x3570, 0x3571, and 0x3d73 are
  marked as 2057x (2nd gen) not 2037x (1st gen).
- Correct PCI device table so device 0x3d17 is marked as 40518
  (2nd gen 4 ports) not 20319 (1st gen 4 ports).
- Correct pdc_ata_init_one() to treat 20771 as a second-generation chip.

Tested on 0x3d75 (2nd gen), 0x3d73 (2nd gen), and 0x3373 (1st gen) chips.
The information comes from the newly uploaded Promise SATA HW specs,
Promise's ultra and ulsata2 drivers, and debugging on 3d75/3d73/3373 chips.

hp->hotplug_offset could now be removed and its value recomputed
in pdc_host_init() using hp->flags, but that would be a cleanup
not a functional change, so I'm ignoring it for now.

Tejun Heo [Fri, 10 Nov 2006 09:08:10 +0000]
[PATCH] ata_piix: apply device detection via polling IDENTIFY

PATA PIIX uses reset signature + TF r/w test for device presence
detection, which doesn't always work.  It sometimes reports phantom
device which results in IDENTIFY timeouts.

SATA PIIX uses some combination of PCS + reset signature + TF r/w test
for device presence detection.  No combination satifies all and for
some controllers, there doesn't seem to be any combination which
works reliably.

This patch makes both PATA and SATA piix's use reset signature + TF
r/w + polling IDENTIFY for device detection.  This is what the old
libata (before irq-pio and new EH) did and what IDE does.

This patch also removes now obsolete PIIX_FLAG_IGNORE_PCS, force_pcs
and related code.

[PATCH] libata: implement presence detection via polling IDENTIFY

On some controllers (ICHs in piix mode), there is *NO* reliable way to
determine device presence other than issuing IDENTIFY and see how the
transaction proceeds by watching the TF status register.

libata acted this way before irq-pio and phantom devices caused very
little problem but now that IDENTIFY is performed using IRQ drive PIO,
such phantom devices now result in multiple 30sec timeouts during
boot.

This patch implements ATA_FLAG_DETECT_POLLING.  If a LLD sets this
flag, libata core issues the initial IDENTIFY in polling mode and if
the initial data transfer fails w/ HSM violation, the port is
considered to be empty thus replicating the old libata and IDE
behavior.

[PATCH] libata: use FLUSH_EXT only when driver is larger than LBA28 limit

Many drives support LBA48 even when its capacity is smaller than
1<<28, as LBA48 is required for many functionalities.  FLUSH_EXT is
mandatory for drives w/ LBA48 support.

Interestingly, at least one of such drives (ST960812A) has problems
dealing with FLUSH_EXT.  It eventually completes the command but takes
around 7 seconds to finish in many cases thus drastically slowing down
IO transactions.  This seems to be a firmware bug which sneaked into
production probably because no other ATA driver including linux IDE
issues FLUSH_EXT to drives which report support for LBA48 & FLUSH_EXT
but is smaller than 1<<28 blocks.

This patch adds ATA_DFLAG_FLUSH_EXT which is set iff the drive
supports LBA48 & FLUSH_EXT and is larger than LBA28 limit.  Both cache
flush paths are updated to issue FLUSH_EXT only when the flag is set.
Note that the changed behavior is more inline with the rest of libata.
libata prefers shorter commands whenever possible.

Tejun Heo [Wed, 1 Nov 2006 09:39:27 +0000]
[PATCH] libata: implement ATA_EHI_SETMODE and ATA_EHI_POST_SETMODE

libata EH used to perform ata_set_mode() iff the EH session performed
reset as indicated by ATA_EHI_DID_RESET.  This is incorrect because
->dev_config() called by revalidation is allowed to modify transfer
mode which ata_set_mode() should take care of.  This patch implements
the following two flags.

* ATA_EHI_SETMODE: set during EH to schedule ata_set_mode().  Both new
  device attachment and revalidation set this flag.

* ATA_EHI_POST_SETMODE: set while the device is revalidated after
  ata_set_mode().  Post-setmode revalidation is different from initial
  configuaration and EH revalidation in that ->dev_config() is not
  allowed tune transfer mode.  LLD can use this flag to determine
  whether it's allowed to tune transfer mode.  Note that POST_SETMODE
  ->dev_config() is guaranteed to be preceded by non-POST_SETMODE
  ->dev_config().

[PATCH] libata: handle 0xff status properly

libata waits for !BSY even when the status register reports 0xff.
This causes long boot delays when D8 isn't pulled down properly.  This
patch does the followings.

* don't wait if status register is 0xff in all wait functions

* make ata_busy_sleep() return 0 on success and -errno on failure.
  -ENODEV is returned on 0xff status and -EBUSY on other failures.

* make ata_bus_softreset() succeed on 0xff status.  0xff status is not
  reset failure.  It indicates no device.  This removes unnecessary
  retries on such ports.  Note that the code change assumes unoccupied
  port reporting 0xff status does not produce valid device signature.

  instead of them being pushed in by the CPU)

- Full 64-bit DMA support

ADMA mode is enabled by default in this version.  To disable it, set the
module parameter adma_enabled=0.

David Brownell [Fri, 17 Nov 2006 07:28:47 +0000]
Driver core: platform_driver_probe(), can save codespace

This defines a new platform_driver_probe() method allowing the driver's
probe() method, and its support code+data, to safely live in __init
sections for typical system configurations.

Many system-on-chip processors could benefit from this API, to the tune
of recovering hundreds to thousands of bytes per driver.  That's memory
which is currently wasted holding code which can never be called after
system startup, yet can not be removed.   It can't be removed because of
the linkage requirement that pointers to init section code (like, ideally,
probe support) must not live in other sections (like driver method tables)
after those pointers would be invalid.

Provide a function device_move() to move a device to a new parent device. Add
auxilliary functions kobject_move() and sysfs_move_dir().
kobject_move() generates a new uevent of type KOBJ_MOVE, containing the
previous path (DEVPATH_OLD) in addition to the usual values. For this, a new

Thomas Maier [Sun, 22 Oct 2006 17:17:47 +0000]
sysfs: sysfs_write_file() writes zero terminated data

since most of the files in sysfs are text files,
it would be nice, if the "store" function called
during sysfs_write_file() gets a zero terminated
string / data.
The current implementation seems not to ensure this.
(But only if it is the first time the zeroed buffer
page is allocated.)

So the buffer can be scanned by sscanf() easily,
for example.

This patch simply sets a \0 char behind the
data in buffer->page.

cpu topology: consider sysfs_create_group return value

Take return value of sysfs_create_group() into account.  That function got
called in case of CPU_ONLINE notification.  Since callbacks are not allowed
to fail on CPU_ONLINE notification do the sysfs group creation on
CPU_UP_PREPARE notification.

Also remember if creation succeeded in a bitmask.  So it's possible to know
whether it's legal to call sysfs_remove_group or not.

In addition some other minor stuff:

- since CPU_UP_PREPARE might fail add CPU_UP_CANCELED handling as well.
- use hotcpu_notifier instead of register_hotcpu_notifier.
- #ifdef code that isn't needed in the !CONFIG_HOTPLUG_CPU case.

Move the call to platform_notify_remove() to after the call to

of removal while drivers are still attached to the device and possibly

and different card attribute files can hang off of. /sys/class/sound is
