libFC is composed of 4 blocks supported by an exchange manager
and a framing library. The upper 4 layers are fc_lport, fc_disc,
fc_rport and fc_fcp. A LLD that uses libfc could choose to
either use libfc's block, or using the transport template
defined in libfc.h, override one or more blocks with its own
implementation.
The EM (Exchange Manager) manages exhcanges/sequences for all
commands- ELS, CT and FCP.
The framing library frames ELS and CT commands.
The fc_lport block manages the library's representation of the
host's FC enabled ports.
The fc_disc block manages discovery of targets as well as
handling changes that occur in the FC fabric (via. RSCN events).
The fc_rport block manages the library's representation of other
entities in the FC fabric. Currently the library uses this block
for targets, its peer when in point-to-point mode and the
directory server, but can be extended for other entities if
needed.
The fc_fcp block interacts with the scsi-ml and handles all
I/O.

Some of the storage devices (that can be accessed through multiple paths),
do need some special handling for
1. Activating the passive path of the storage access.
2. Decode and handle the special sense codes returned by the devices.
3. Handle the I/Os being sent to the passive path, especially
during the device probe time.
when accessed through multiple paths.
As of today this special device handling is done at the dm-multipath
layer using dm-handlers. That works well for (1); for (2) to be handled
at dm layer, scsi sense information need to be exported from SCSI to dm-layer,
which is not very attractive; (3) cannot be done at all at the dm layer.
Device handler has been moved to SCSI mainly to handle (2) and (3) properly.

This adds support to SCSI for enclosure services devices. It also makes
use of the enclosure services added in an earlier patch to display the
enclosure topology in sysfs.
At the moment, the enclosures are SAS specific, but if anyone actually
has a non-SAS enclosure that follows the SES-2 standard, we can add that
as well.
On my Vitesse based system, the enclosures show up like this:

And the individual occupied slots like this:

You can flash the various blinky lights by echoing to the fault and locate files.
>From the device's point of view, you can see it has an enclosure like this:
sparkweed:~# ls /sys/class/scsi_disk/0\:0\:0\:0/device/
block:sda generic queue_depth state
bsg:0:0:0:0 iocounterbits queue_type subsystem
bus iodone_cnt rescan timeout

driver modalias scsi_disk:0:0:0:0 vendor
enclosure_component:SLOT 001 model scsi_generic:sg0
evt_media_change power scsi_level
Note the enclosure_component:SLOT 001 which shows where in the enclosure
this device fits.
The astute will notice that I'm using SCSI VPD Inquiries to identify the
devices. This, unfortunately, won't work for SATA devices unless we do
some really nasty hacking about on the SAT because the only think that
knows the SAS addresses for SATA devices is libsas, not libata where the
SAT resides.

SCSI should be working on a TT (but someone should really try!) but causes
trouble on a Falcon (as in: it ate a filesystem of mine) at least when
used concurrently with IDE. I have the notion it's because locking of the
ST-DMA interrupt by IDE is broken in 2.6 (the IDE driver always complains
about trying to release an already-released ST-DMA). Needs more work, but
that's on the IDE or m68k interrupt side rather than SCSI.

Make it possible to disable the block layer. Not all embedded devices require
it, some can make do with just JFFS2, NFS, ramfs, etc - none of which require
the block layer to be present.
This patch does the following:
(*) Introduces CONFIG_BLOCK to disable the block layer, buffering and blockdev
support.
(*) Adds dependencies on CONFIG_BLOCK to any configuration item that controls
an item that uses the block layer. This includes:
(*) Block I/O tracing.
(*) Disk partition code.
(*) All filesystems that are block based, eg: Ext3, ReiserFS, ISOFS.
(*) The SCSI layer. As far as I can tell, even SCSI chardevs use the
block layer to do scheduling. Some drivers that use SCSI facilities -
such as USB storage - end up disabled indirectly from this.
(*) Various block-based device drivers, such as IDE and the old CDROM
drivers.
(*) MTD blockdev handling and FTL.
(*) JFFS - which uses set_bdev_super(), something it could avoid doing by
taking a leaf out of JFFS2's book.
(*) Makes most of the contents of linux/blkdev.h, linux/buffer_head.h and
linux/elevator.h contingent on CONFIG_BLOCK being set. sector_div() is,
however, still used in places, and so is still available.
(*) Also made contingent are the contents of linux/mpage.h, linux/genhd.h and
parts of linux/fs.h.
(*) Makes a number of files in fs/ contingent on CONFIG_BLOCK.
(*) Makes mm/bounce.c (bounce buffering) contingent on CONFIG_BLOCK.
(*) set_page_dirty() doesn't call __set_page_dirty_buffers() if CONFIG_BLOCK
is not enabled.
(*) fs/no-block.c is created to hold out-of-line stubs and things that are
required when CONFIG_BLOCK is not set:
(*) Default blockdev file operations (to give error ENODEV on opening).
(*) Makes some /proc changes:
(*) /proc/devices does not list any blockdevs.
(*) /proc/diskstats and /proc/partitions are contingent on CONFIG_BLOCK.
(*) Makes some compat ioctl handling contingent on CONFIG_BLOCK.
(*) If CONFIG_BLOCK is not defined, makes sys_quotactl() return -ENODEV if
given command other than Q_SYNC or if a special device is specified.
(*) In init/do_mounts.c, no reference is made to the blockdev routines if
CONFIG_BLOCK is not defined. This does not prohibit NFS roots or JFFS2.
(*) The bdflush, ioprio_set and ioprio_get syscalls can now be absent (return
error ENOSYS by way of cond_syscall if so).
(*) The seclvl_bd_claim() and seclvl_bd_release() security calls do nothing if
CONFIG_BLOCK is not set, since they can't then happen.

This patch formally adds support for the posting of FC events via netlink.
It is a followup to the original RFC at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=114530667923464&w=2
and the initial posting at:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115507374832500&w=2
The patch has been updated to optimize the send path, per the discussions
in the initial posting.
Per discussions at the Storage Summit and at OLS, we are to use netlink for
async events from transports. Also per discussions, to avoid a netlink
protocol per transport, I've create a single NETLINK_SCSITRANSPORT protocol,
which can then be used by all transports.
This patch:
- Creates new files scsi_netlink.c and scsi_netlink.h, which contains the
single and shared definitions for the SCSI Transport. It is tied into the
base SCSI subsystem intialization.
Contains a single interface routine, scsi_send_transport_event(), for a
transport to send an event (via multicast to a protocol specific group).
- Creates a new scsi_netlink_fc.h file, which contains the FC netlink event
messages
- Adds 3 new routines to the fc transport:
fc_get_event_number() - to get a FC event #
fc_host_post_event() - to send a simple FC event (32 bits of data)
fc_host_post_vendor_event() - to send a Vendor unique event, with
arbitrary amounts of data.
Note: the separation of event number allows for a LLD to send a standard
event, followed by vendor-specific data for the event.
Note: This patch assumes 2 prior fc transport patches have been installed:
http://marc.theaimsgroup.com/?l=linux-scsi&m=115555807316329&w=2http://marc.theaimsgroup.com/?l=linux-scsi&m=115581614930261&w=2

Let people enable the advansys driver on x86-32, even though it's broken
on other architectures due to missing DMA mapping infrastructure.
It's used by Jeffrey Phillips Freeman <jeffreyfreeman@syncleus.com> and
possibly others.

Most of the Kconfig options for switching between IO Port and MMIO
operations use the opposite sense from sym2. Really, this option
should be set at a chipset level rather than per-driver.

scsi_print_msg() is an SPI-specific concept. This patch moves it from
constants.c to scsi_transport_spi.c and updates the Kconfig to link in
the SPI class for the drivers which use scsi_print_msg().

This change makes quirk_intel_ide_combined() dependent on the precise
conditions under which it is needed:
* IDE is built in
* IDE SATA option is not set
* ata_piix or ahci drivers are enabled
This fixes an issue where some modular configurations would not cause
the quirk to be enabled.

Now it looks like we'll have multiple users of the iscsi transport
class, the iscsi initiator shouldn't really be a dependency of it. This
patch moves iscsi to being an initiator in its own right which selects
the transport attributes.

The SAS transport class contains common code to deal with SAS HBAs, an
aproximated representation of SAS topologies in the driver model,
and various sysfs attributes to expose these topologies and managment
interfaces to userspace.
In addition to the basic SCSI core objects this transport class introduces
two additional intermediate objects: The SAS PHY as represented by struct
sas_phy defines an "outgoing" PHY on a SAS HBA or Expander, and the SAS
remote PHY represented by struct sas_rphy defines an "incoming" PHY on a
SAS Expander or end device. Note that this is purely a software concept, the
underlying hardware for a PHY and a remote PHY is the exactly the same.
There is no concept of a SAS port in this code, users can see what PHYs
form a wide port based on the port_identifier attribute, which is the same
for all PHYs in a port.
This submission doesn't handle hot-plug addition or removal of SAS devices
and thus doesn't do scanning in a workqueue yet, that will be added in
phase2 after this submission. In a third phase I will add additional
managment infrastructure.
I think this submission is ready for 2.6.14, but additional comments are
of course very welcome.
I'd like to thanks James Smart a lot for his very useful input on the
design.

This is my libata compatible low level driver for the Marvell SATA
family. Currently it successfully runs in PIO mode on a 6081 chip.
EDMA support is in the works and should be done shortly. Review,
testing (especially on other flavors of Marvell), comments welcome.

The idea behind a RAID class is to provide a uniform interface to all
RAID subsystems (both hardware and software) in the kernel.
To do that, I've made this class a transport class that's entirely
subsystem independent (although the matching routines have to match per
subsystem, as you'll see looking at the code). I put it in the scsi
subdirectory purely because I needed somewhere to play with it, but it's
not a scsi specific module.
I used a fusion raid card as the test bed for this; with that kind of
card, this is the type of class output you get:
jejb@titanic> ls -l /sys/class/raid_devices/20\:0\:0\:0/
total 0
lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-0 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:0/20:1:0:0/
lrwxrwxrwx 1 root root 0 Aug 16 17:21 component-1 -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:1:1/20:1:1:0/
lrwxrwxrwx 1 root root 0 Aug 16 17:21 device -> ../../../devices/pci0000:80/0000:80:04.0/host20/target20:0:0/20:0:0:0/
-r--r--r-- 1 root root 16384 Aug 16 17:21 level
-r--r--r-- 1 root root 16384 Aug 16 17:21 resync
-r--r--r-- 1 root root 16384 Aug 16 17:21 state
So it's really simple: for a SCSI device representing a hardware raid,
it shows the raid level, the array state, the resync % complete (if the
state is resyncing) and the underlying components of the RAID (these are
exposed in fusion on the virtual channel 1).
As you can see, this type of information can be exported by almost
anything, including software raid.
The more difficult trick, of course, is going to be getting it to
perform configuration type actions with writable attributes.
