MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Hello,

This patch adds the Intel ICH7-M DH DID to the ahci.c file for AHCI mode SATA support.  This patch was built against the 2.6.13-rc6 kernel.  
If acceptable, please apply.

Thanks,

Jason Gaston

Subject: [PATCH] libata ata_data_xfer() fix

PATCH 1/2: ata_data_xfer() fix

Changes:
   - Modify ata_mmio_data_xfer() and ata_pio_data_xfer() to handle odd-lengthed buffer.
   - Add some function comments

This patch does not reuse ap->pad as alignment buffer since
using local variable seems good enough.

PATCH 2/2:  handle the case when device returns/needs extra data

Description:
   Sometimes the device returns/needs extra data than expected.

Changes:
   Modify __atapi_pio_bytes() to handle the case where device returns/needs extra data.
     - for read case, discard trailing data from the device
     - for write case, padding zero data to the device

Description:
  After calling the completion callback, the libata error handler might be
running and getting atapi sense data. Clearing the ATA_QCFLAG_ACTIVE flag
at this point might interfere with the libata error handler.

Changes:
   - Clear the ATA_QCFLAG_ACTIVE flag before calling the completion callback
     (and also before the error handler)
   - Add some comment

Subject: [PATCH] Fix HD activity LED with ahci

Patch: fix wrong HD activity control by ahci driver

The ahci driver 1.0 sets the SActive bit on every transaction,
causing the LED to light up. The SActive bit is used only for
native command queuing (NCQ) which the current driver version
doesn't implement. Resetting the SActive bit is the device's
responsibility (by sending a "Set Device Bits FIS" to the
host adapter) but this is not required in response to
non-NCQ commands, and (most) devices don't. Thus the LED
stays always on. This patch fixes the LED behavior.

Subject: [PATCH] fix atapi_packet_task vs. intr race (take 2)

Interrupts from devices sharing the same IRQ could cause
ata_host_intr to finish commands being processed by atapi_packet_task
if the commands are using ATA_PROT_ATAPI_NODATA or ATA_PROT_ATAPI_DMA
protocol.  This is because libata interrupt handler is unaware that
interrupts are not expected during that period.  This patch adds
ATA_FLAG_NOINTR flag to tell the interrupt handler that we're not
expecting interrupts.

 Note that once proper HSM is implemented for interrupt-driven PIO,
this should be merged into it and this flag will be removed.

 ahci.c is a different kind of beast, so it's left alone.

* The following drivers use ata_qc_issue_prot and ata_interrupt, so
  changes in libata core will do.

  ata_piix sata_sil sata_svw sata_via sata_sis sata_uli

* The following drivers use ata_qc_issue_prot and custom intr handler.
  They need this change to work correctly.

  sata_nv sata_vsc

* The following drivers use custom issue function and intr handler.
  Currently all custom issue functions don't support ATAPI, so this
  change is irrelevant, updated for consistency and to avoid later
  mistakes.

Subject: [PATCH] libata: implement ata_poll_qc_complete and use it in polling
 functions

[PATCH libata-dev-2.6:upstream] implement ata_poll_qc_complete and use it in polling functions

 Previously, libata polling functions turned irq back on and completed
qc commands without holding host lock.  This creates a race condition
between the polling task and interrupts from other ports on the same
host set or spurious interrupt from itself.

 This patch implements ata_poll_qc_complete which enables irq and
completes qc atomically and convert all polling functions.

 Note: atapi_packet_task() didn't use to turn irq back on or clear
ATA_FLAG_NOINTR on error exits.  This patch makes it use
ata_poll_qc_complete which does both.

 Note: With this change, ALL invocations of ata_qc_complete() are now
done under host_set lock.

Subject: [PATCH] sil: apply M15W quirk selectively (take 2)

 As SII reports that only original 3112's are affected by M15W quirk,
This patch adds SIL_FLAG_MOD15WRITE to selectively apply M15W quirk
depending on chipsets.  As of yet, we don't know exactly which PCI IDs
are for original 3112, so M15W quirk is applied to all except for 3512
and 3124.  Once more info is avaliable, we can change some of these
sil_3112_m15w's to sil_3112.

Subject: [libata scsi] fix read/write translation edge cases

Fix bugs for unlikely edge cases noticed by Douglas Gilbert:

- When READ(6)/WRITE(6) sector count == 0, treat it as 256 sectors

- For other READ(x)/WRITE(x), when sector count == 0, error.
  We don't support successfully completing zero-length transfers at
  this time.

Subject: [PATCH] sg.c: fix a memory leak in devices seq_file implementation

I know that scsi procfs is legacy code but this is a fix for a memory leak.

While reading through sg.c I realized that the implementation of
/proc/scsi/sg/devices with seq_file is leaking memory due to freeing the
pointer returned by the next() iterator method.  Since next() might return
NULL or an error this is wrong.  This patch fixes it through using the
seq_files private field for holding the reference to the iterator object.

Here is a small bash script to trigger the leak. Use slabtop to watch
the size-32 usage grow and grow.

#!/bin/sh

while true; do
	cat /proc/scsi/sg/devices > /dev/null
done
