qla4xxx has the old school startup/probe where it finds presetup sessions
in its flash and then attempts to log into them before returning from the
probe. This however, makes it very simple to add a iscsi class scan finished
helper which the driver can use.
In future patches Dave or I will rip apart the driver to make it more
like qla2xxx, but for now this is a very simple two line patch which
fixes the problem of trying to figure out when the initial sessions
are done being scanned.

Qla4xxx can just call the iscsi recovery functions directly.
There is no need for userspace to do this for qla4xxx, because
we do not use the mutex to iterate over devices anymore and iscsi_block
/unblock_session can be called from interrupt context or the dpc thread.
And having userspace do this just creates uneeded headaches for qla4xxx root
situations where the session may experience problems. For example
during the kernel shutdown the scsi layer wants to send sync caches, but at
this time userspace is not up (iscsid is not running), so we cannot
recover from the problem.

This is a one-line patch to add the following to __scsi_alloc_queue():
dma_set_seg_boundary(dev, shost->dma_boundary);
This is the simplest approach but the result looks odd,
__scsi_alloc_queue() does:
blk_queue_segment_boundary(q, shost->dma_boundary);
dma_set_seg_boundary(dev, shost->dma_boundary);
blk_queue_max_segment_size(q, dma_get_max_seg_size(dev));
I think that it would be better to set up segment boundary in the same
way as we did for the maximum segment size. That is, removing
shost->dma_boundary and LLDs call pci_set_dma_seg_boundary (or its
friends).
Then __scsi_alloc_queue() can set up both limits in the same way:
blk_queue_segment_boundary(q, dma_get_seg_boundary(dev));
blk_queue_max_segment_size(q, dma_get_max_seg_size(dev));
killing dma_boundary in scsi_host_template needs a large patch for
libata (dma_boundary is used by only libata and sym53c8xx). I'll send
a patch to do that if it is acceptable. James and Jeff?

Convert the io_req_t members to unsigned int, to allow use on machines with
more than 16 bits worth of IO ports (i.e. secondary busses on ppc64, etc).
There was only a couple of places in drivers where a change was needed. I
left printk formats alone (there are lots of %04x-style formats in there),
mostly to not change the format on the platforms that only have 16-bit io
addresses, but also because the padding doesn't really add all that much value
most of the time.
I found only one sprintf of an address, and upsized the string accordingly (I
doubt anyone will have anywhere near INT_MAX as irq value, but at least
there's room for it now).

Building the aic7xxx driver includes the copy
of an .h file from a _shipped file.
In a highly parallel build Ingo saw that the
build sometimes failed (included distcc usage).
It was tracked down to a missing dependency from the .c
source file to the generated .h file.
We started to build the .c file before the
copy (cat) operation of the .h file completed
and we then only got half of the definitions
from the copied .h file.
Add an explicit dependency from the .c files to the
generated .h files so make knows all dependencies and
finsih the build of the .h files before it starts
building the .o files.
Ingo tested this fix and reported:
good news: hundreds of successful kernel builds and no failures
overnight.

At the block level bidi request uses req->next_rq pointer for a second
bidi_read request.
At Scsi-midlayer a second scsi_data_buffer structure is used for the
bidi_read part. This bidi scsi_data_buffer is put on
request->next_rq->special. Struct scsi_cmnd is not changed.
- Define scsi_bidi_cmnd() to return true if it is a bidi request and a
second sgtable was allocated.
- Define scsi_in()/scsi_out() to return the in or out scsi_data_buffer
from this command This API is to isolate users from the mechanics of
bidi.
- Define scsi_end_bidi_request() to do what scsi_end_request() does but
for a bidi request. This is necessary because bidi commands are a bit
tricky here. (See comments in body)
- scsi_release_buffers() will also release the bidi_read scsi_data_buffer
- scsi_io_completion() on bidi commands will now call
scsi_end_bidi_request() and return.
- The previous work done in scsi_init_io() is now done in a new
scsi_init_sgtable() (which is 99% identical to old scsi_init_io())
The new scsi_init_io() will call the above twice if needed also for
the bidi_read command. Only at this point is a command bidi.
- In scsi_error.c at scsi_eh_prep/restore_cmnd() make sure bidi-lld is not
confused by a get-sense command that looks like bidi. This is done
by puting NULL at request->next_rq, and restoring.

Subject: [trivial patch] scsi/ultrastor: clean up inline asm warnings
Hi,
Compiling latest mainline with gcc 4.2.1 spews the following warnings:

The following patch fixes it by using the '+' operator on the (*field)
operand, marking it as read-write to gcc. I diffed the two resulting .s,
and gcc produced the same code. This was tested with gcc 4.2.1 and gcc 3.4.3

possibility that parallel make with a different output directory can
fail.

Alan noticed the lack of locking surrounding the driver's dealings
with the fib context managed by the trio of ioctls that are used by
the RAID management applications to retrieve Adapter Initiated FIBs. I
merely expanded the fib lock to include the fib context. There have
been no field reports of any issues generally because the applications
are relatively static and do not come and go often enough to stress
this area. I bloated this patch a little with some space junk.

ch_probe uses the total number of ch devices as minor.
ch_probe:
ch->minor = ch_devcount;
...
ch_devcount++;
Then ch_remove decreases ch_devcount:
ch_remove:
ch_devcount--;
If you have two ch devices, sch0 and sch1, and remove sch0,
ch_devcount is 1. Then if you add another ch device, ch_probe tries to
create sch1. So you get a warning and fail to create sch1:

I've verified (on my Initio 9100 with a DAT drive) that the
2.6.24-rc8-git6 initio module still hangs on loading.
These fixes (other than the printk) are needed to get the module to load
ok (and work correctly) with my adapter & tape drive.
a) printk cosmetic fix
b) cblk->sglen needs setting for later DMA I/O routines to use
c) host->bios_addr needs setting for debug output correctness
d) semaph & semaph_lock initialisation had got lost since 2.6.22
e) since 2.6.22 the bios data address was truncated to 16 bits (needs 20
when shifted left)

The patch "[SCSI] sg: use idr to replace static arrays" in 2.6.24-rc1
causes a bogus line to appear in /proc/scsi/sg/devices containing
"-1 -1 -1 -1 -1 -1 -1 -1 -1" when there are no SCSI devices in the
system. In 2.6.23, /proc/scsi/sg/devices is empty when there are no
SCSI devices in the system. A similar problem exists with
/proc/scsi/sg/device_strs. The following patch restores the behavior
of 2.6.23.

This removes static array sense_buffer in scsi_cmnd and uses
dynamically allocated sense_buffer (with GFP_DMA).
The reason for doing this is that some architectures need cacheline
aligned buffer for DMA:
http://lkml.org/lkml/2007/11/19/2
The problems are that scsi_eh_prep_cmnd puts scsi_cmnd::sense_buffer
to sglist and some LLDs directly DMA to scsi_cmnd::sense_buffer. It's
necessary to DMA to scsi_cmnd::sense_buffer safely. This patch solves
these issues.
__scsi_get_command allocates sense_buffer via kmem_cache_alloc and
attaches it to a scsi_cmnd so everything just work as before.

[SCSI] make pcmcia directory use obj-y|m instead of subdir-y|m
Moved the scsi Makefile into conformance, but also caused the pcmcia
subdirectory to get built in for the first time, leading to duplicate
symbols in an allyesconfig build. Since evidently no-one relies on
these being built in, fix this by ensuring they can only be built as
modules.

The cards being added are supported in a limited sense already through
family matching, but we needed to add some functionality to the driver
to expose selectively the physical drives. These Physical drives are
specifically marked to not be part of any array and thus are declared
JBODs (Just a Bunch Of Drives) for generic SCSI access.
We report that this is the second patch in a set of two, but merely
depends on the stand-alone functionality of the first patch which adds
in that case the ability to report a driver feature flag via sysfs. We
leverage that functionality by reporting that this driver now supports
this new JBOD feature for the controller so that the array management
applications may react accordingly and guide the user as they manage
the controller.

Feature enhancement, adding a 'flags' entry that will reside in the
host controller's tree, with a newline separated list of arbitrary
ascii named features that indicate whether the combination of driver
and controller has support for said feature. Breaking from the
one-line output typical of sysfs entries, newline was added to tailor
for grep, or simple gets line by line string match within an
application. I added one for a compiler time check for existence of
debug print output, one for an optional manifest defined enhanced
status reporting in the logs, and one for runtime reporting whether
the controller and driver supports arrays larger than 2TB. Adaptec's
storage management software uses the last flag to determine whether to
make available the creation of arrays larger than 2TB, otherwise a
warning is posted.

FCE support enables the firmware to record FC extended link
services and basic link services frames which have been
transmitted and received by the ISP. This allows for a limited
view of the FC traffic through the ISP without using a FC
analyzer. This can be useful in situations where a physical
connection to the FC bus is not possible.
The driver exports this information in two ways -- first, via a
debugfs node exported for all supported ISPs under:
<debugfs_mount_point>/qla2xxx/qla2xxx_<host_no>/fce
where a read of the 'fce' file will provide a snapshot of the
firmware's FCE buffer; and finally, the FCE buffer will be
extracted during a firmware-dump scenario.
