13 years agolibata: add support for READ/WRITE LONG
Mark Lord [Fri, 16 Mar 2007 14:22:26 +0000]
libata: add support for READ/WRITE LONG

The READ/WRITE LONG commands are theoretically obsolete,
but the majority of drives in existance still implement them.

The WRITE_LONG and WRITE_LONG_ONCE commands are of particular
interest for fault injection testing -- eg. creating "media errors"
at specific locations on a disk.

The fussy bit is that these commands require a non-standard
sector size, usually 520 bytes instead of 512.

This patch adds support to libata for READ/WRITE LONG commands
issued via SG_IO/ATA_16.

Add notation that the Asus W5F laptop has a short cable instead of 80-wire.

The Asus W5F laptop uses a short cable instead of the 80-wire style, and thus
needs to be in the ich_laptop special cases for correct detection and support
of UDMA/100 for the hard drive. I noticed this because I have the W5F laptop,
and was tracing apparent slowness.

sata_nv: don't read shadow registers when in ADMA mode

Reading from the ATA shadow registers while we are in ADMA mode may cause
undefined behavior.  Don't read the ATA status register when completing
commands for this reason, it shouldn't be needed as the controller will
notify us if the command failed.  Also, don't allow commands with result
taskfile requested to execute in ADMA mode, since that requires accessing
the shadow registers.  We also still need to override tf_read since libata
will read the result taskfile on a command failure, and we need to go into

Mikael Pettersson [Sun, 11 Mar 2007 20:20:43 +0000]
sata_promise: separate SATA and PATA ops

This patch changes sata_promise so that the PATA ports
on TX2plus chips are bound to the pdc_pata_ops structure.
This means that operations called from the SATA ops
structures don't need any SATA-vs-PATA tests any more.
Instead, operations that depend on a port being SATA or
PATA are separated into different procedures.

* pdc_cable_type() is split into a PATA version and a
  SATA version
* pdc_error_handler() is split into a PATA version and a
  SATA version, that both call a common version after
  setting up the `hardreset' function pointer
* pdc_old_check_atapi_dma() is now only used for SATAI
  ports, so is renamed to pdc_old_sata_check_atapi_dma()
  and simplified
* pdc_sata_scr_{read,write}() are now only used for SATA
  ports, so their is-not-SATA tests are removed
* pdc_port_start() is split into three procedures: a wrapper
  which performs the ->ops adjustment on TX2plus PATA ports,
  a procedure with the common code, and a procedure with
  the SATA-specific code (this bit might be cleaned up by
  Tejun's new init model)

Tested on 20619, 20575, and 20775 chips.

libata/IDE: remove combined mode quirk

Both old-IDE and libata should be able handle all controllers and
devices found using normal resource reservation methods.

This eliminates the awful, low-performing split-driver configuration
where old-IDE drove the PATA portion of a PCI device, in PIO-only mode,
and libata drove the SATA portion of the /same/ PCI device, in DMA mode.
Typically vendors would ship SATA hard drive / PATA optical
configuration, which would lend itself to slow (PIO-only) CD-ROM
performance.

For Intel users running in combined mode, it is now wholly dependent on
your driver choice (potentially link order, if you compile both drivers
in) whether old-IDE or libata will drive your hardware.

In either case, you will get full performance from both SATA and PATA
ports now, without having to pass a kernel command line parameter.

that meant each type had its own error_handler methods. Instead we can

error_handler which does the filtering by enable bits.

We add a ->cable_detect() method called after the identify
sequence which allows a host to do host side detection at this point
should it wish, or to modify the results of the drive side identify.

This separate ->cable_detect method also cleans up a lot of code because
many drivers have their own error_handler methods which really just set
the cable type.

If there is no ->cable_detect method the cable type is left alone so a
driver setting it earlier (eg because it has the SATA flags set or
because it uses the old error_handler approach) will still do the right
thing (or at least the same thing) as before.

This patch simply adds the cable_detect method and helpers it doesn't use
them but other follow up patches will (ie Adrian please don't submit
patches to unexport them ;))

[libata] sata_mv: clean up DMA boundary issues, turn on 64-bit DMA

The chips covered by sata_mv have a 32-bit DMA boundary they must not
cross, not a 64K boundary.  We are merely limited to a 64K maximum
segment size.  Therefore, the DMA scatter/gather table fill code can be
greatly simplified, and we need not cut in half the S/G table size as
reported to the SCSI layer.

Also, the driver forget to turn on 64-bit DMA at the PCI layer.  All
other data structures (both hardware and software) have been prepped for
64-bit PCI DMA.  It was simply never turned on.  <fingers crossed> let's

13 years agosis900: Allocate rx replacement buffer before rx operation
Neil Horman [Thu, 26 Apr 2007 17:47:36 +0000]
sis900: Allocate rx replacement buffer before rx operation

Just found a hole in my last patch.  It was reported to me that shortly after we
integrated this patch.  The report was of an oops that took place inside of
netif_rx when using the sis900 driver.  Looking at my origional patch I noted
that there was a spot between the new skb_alloc and the refill_rx_ring label
where skb got reassigned to the pointer currently held in the rx_ring for the
purposes of receiveing the frame.  The result of this is however that the buffer
that gets passed to netif_rx (if it is called), then gets placed right back into
the rx_ring.  So if you receive frames fast enough the skb being processed by
the network stack can get corrupted.  The reporter is testing out the fix I've
written for this below (I'm not near my hardware at the moment to test myself),
but I wanted to post it for review ASAP.  I'll post test results when I hear
them, but I think this is a pretty straightforward fix.  It just uses a separate
pointer to do the rx operation, so that we don't improperly reassign the pointer
that we use to refill the rx ring.

Eberhard Fahle [Thu, 5 Apr 2007 09:13:21 +0000]
USB: iowarrior.c: timeouts too small in usb_control_msg calls

The driver uses usb_control_msg() for exchanging data with the device.
When the driver lived freeley _outside_ the kernel tree (pre 2.6.21) the
timeouts for these calls where set to 5*HZ for reading, 1HZ for writing.
(These timeouts seemed to work fine for all users of the driver, at
least nobody complained in the last 2 years.

The current code (2.6.21-rc5) removed the 'HZ' from the timeouts and
left the driver with 5 jiffies for reading and 1 jiffy for writing. My
new machine is fast, but not that fast.

The patch also removes a useless debug statement, which was left over
from testing a broken firmware version

sysfs attribute to allow it to be started/stopped/restarted.  It also stops

usbmon: bus zero

Add the "bus zero" feature to the usbmon. If a user process specifies bus
with number zero, it receives events from all buses. This is useful when
we wish to see initial enumeration when a bus is created, typically after
a modprobe. Until now, an application had to loop until a new bus could
be open, then start capturing on it. This procedure was cumbersome and
could lose initial events. Also, often it's too bothersome to find exactly
to which bus a specific device is attached.

Paolo Albeni provided the original concept implementation. I added the
handling of "bus->monitored" flag and generally fixed it up.

USB: add "last_busy" field for use in autosuspend

This patch (as877) adds a "last_busy" field to struct usb_device, for
use by the autosuspend framework.  Now if an autosuspend call comes at
a time when the device isn't busy but hasn't yet been idle for long
enough, the timer can be set to exactly the desired value.  And we
will be ready to handle things like HID drivers, which can't maintain
a useful usage count and must rely on the time-of-last-use to decide
when to autosuspend.

The patch also makes some related minor improvements:

Move the calls to the autosuspend condition-checking routine
into usb_suspend_both(), which is the only place where it
really matters.

If the autosuspend timer is already running, don't stop
and restart it.

Replace immediate returns with gotos so that the optional
debugging ouput won't be bypassed.

If autoresume is disabled but the device is already awake,
don't return an error for an autoresume call.

Don't try to autoresume a device if it isn't suspended.
(Yes, this undercuts the previous change -- so sue me.)

Don't duplicate existing code in the autosuspend work routine.

Fix the kerneldoc in usb_autopm_put_interface(): If an
autoresume call fails, the usage counter is left unchanged.
