[SCSI] bsg: separate bsg and SCSI (so SCSI can be modular)

This patch moves the bsg registration into SCSI so that bsg no longer
has a dependency on the scsi_interface_register API.

This can be viewed as a temporary expedient until we can get universal
bsg binding sorted out properly.  Also use the sdev bus_id as the
generic bsg name (to avoid clashes with the queue name).

Fix drivers misusing dev_to_shost

Some drivers were using dev_to_shost to go from a struct device to the
corresponding shost.  Unfortunately, dev_to_shost only looks up the tree
to find an shost (it's designed to go from a scsi_device or a
scsi_target to the parent scsi_host), and these drivers were calling it
with the parent of the scsi_host.

I've fixed this by saving a pointer to the Scsi_Host in the drvdata,
which matches what most scsi drivers do.

[SCSI] aacraid: add vpd to inquiry

Report VPD inquiry page 0x80 with an unique array creation serial
number (CUID). When an array is created, the metadata stored on the
physical drives gets an unique serial number. This serial number
remains constant through array morphing or migration to other
controllers.  This patch is a forward port and modification to survive
morphing and migration operations, of a similar piece of
(un-attributed author) code added to the SLES10 SP1 aacraid driver.

To test the results of the patch, observe that /dev/disk/by-id/
entries will show up for the arrays resulting from the udev rules.
Also, as per the udev rules, 'scsi_id -g -x -a -s /block/sd? -d
/dev/sd?'  will report the ID_SERIAL as constructed from the inquiry
data.

It was reported to me that the 'ADPT' leading the serial number was bad
form, that the inquiry vendor field was enough to differentiate the
storage uniquely. Subsequent search found that another Adaptec AAC based
driver reported the 8 hex serial number only without such adornments, so
dropped ADPT to match. Resubmitting the patch with this alteration.

One question remains: Is it necessary to reset the phy on error, or will
the libata error handler take care of it?  (Assuming that one is written,
of course.)  This patch, as it is today, works well enough to clean

[SCSI] aic94xx: add SATAPI support

It turns out this is fairly easy to plumb in by recognising the three
command types and copying the CDB.  The protocol response path needs to

13 years ago[SCSI] libsas: support NCQ for SATA disks
Darrick J. Wong [Fri, 13 Oct 2006 23:56:25 +0000]
[SCSI] libsas: support NCQ for SATA disks

This patch adds SATAII NCQ support to libsas.  Both the use_ncq and the
dma_xfer flags in ata_task must be set for NCQ to work correctly on the
Adaptec SAS controller.  The rest of the patch adds ATA_FLAG_NCQ to
sata_port_info and sets up ap->scsi_host so that ata_setup_ncq doesn't
crash.  Please note that this patch is against the aic94xx-sas git tree,
not scsi-misc.  Thanks also to James Bottomley for providing an earlier
version of this patch from which to work.

I've tested this patch on a x206m with a ST380819AS SATA2 disk plugged
into the Adaptec SAS controller.  The drive came up with a queue depth
of 31, and I successfully ran an I/O flood test to coerce libata into
sending multiple commands simultaneously.  A kernel probe recorded the
maximum tag number that had been seen before and after the flood test;
before the test it was 2 and after it was 30, as I expected.

[SCSI] aic94xx: SATA tag mask not set correctly

The aic94xx controller has a bitmask establishing which tags are ok to
use with a SATA NCQ disk.  When the queue depth is 32, however, the
expression that is used sets the mask to zero, not 0xFFFFFFFF.

James Bottomley [Tue, 22 Aug 2006 17:39:19 +0000]
[SCSI] libsas: Add SATA support to STP piece for SATA on SAS expanders

This patch adds support for SATA over SAS expanders to the previous two
SATA support in libsas patches.

There were a couple of nasty non trivial things to sort out before this
one could be made to work.

Firstly, I'd like to thank Doug Gilbert for diagnosing a problem with
the LSI expanders where the REPORT_SATA_PHY command was returning the
D2H FIS in the wrong order (Although, here, I think I have to blame the
SAS standards which specifies the FIS "shall be returned in little
endian format" and later on "which means resp[24] shall be FIS type"
The latter, of course, implying big endian format).  Just to make sure,
I put a check for the D2H FIS type being in the wrong position and
reverse the FIS data if it is.

The second is a problem outlined in Annex G of the SAS standard (again,
a technical point with D2H FIS ... necessitating a phy reset on certain
conditions).

With the patch, I can now see my SATA-1 disk in a cascaded expander
configuration.

13 years agozs: move to the serial subsystem
Maciej W. Rozycki [Wed, 18 Jul 2007 07:49:11 +0000]
zs: move to the serial subsystem

This is a reimplementation of the zs driver for the serial subsystem.  Any
resemblance to the old driver is purely coincidential.  ;-) I do hope I got
the handling of modem lines right -- better do not tackle me about the
issue unless you feel too good...

Any users of the old driver: please note the numbers of the serial lines
have now been swapped, i.e.  ttyS0 <-> ttyS1 and ttyS2 <-> ttyS3.  It has
to do with the modem lines mentioned above; basically the port A in a given
chip has to be initialised before the port B if you want to use the latter
as the serial console (which is usually the case), as operations on modem
lines of the serial line associated with the port B access both ports (see
the comment at the top of the driver for the details of wiring used).
Please update your scripts.

This is also the reason each SCC now requests an IRQ once only (as seen in
"/proc/interrupts") -- the handler takes care of both ports at once as the
line associated with the port B has to take status update interrupts from
both ports (and yet the line of the port A takes its own for itself too).
The old driver never got it right...

md: change bitmap_unplug and others to void functions

bitmap_unplug only ever returns 0, so it may as well be void.  Two callers try
to print a message if it returns non-zero, but that message is already printed
by bitmap_file_kick.

write_page returns an error which is not consistently checked.  It always
causes BITMAP_WRITE_ERROR to be set on an error, and that can more
conveniently be checked.

When the return of write_page is checked, an error causes bitmap_file_kick to
be called - so move that call into write_page - and protect against recursive
calls into bitmap_file_kick.

bitmap_update_sb returns an error that is never checked.

So make these 'void' and be consistent about checking the bit.

real-time clock(RTC).

The support for RTC is integrated with this driver only; it is not separate

(rdate/ntpdate/etc, then "hwclock -w") then RTC_HCTOSYS at boot time will
