      [SCSI] ses: add new Enclosure ULD · 9927c688
      由 James Bottomley 提交于 
      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:

sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/
total 0
-r--r--r-- 1 root root 4096 2008-02-03 15:44 components
lrwxrwxrwx 1 root root    0 2008-02-03 15:44 device -> ../../../devices/pci0000:01/0000:01:02.0/host0/port-0:0/expander-0:0/port-0:0:12/end_device-0:0:12/target0:0:1/0:0:1:0
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 000
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 001
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 002
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 003
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 004
drwxr-xr-x 2 root root    0 2008-02-03 15:44 SLOT 005
lrwxrwxrwx 1 root root    0 2008-02-03 15:44 subsystem -> ../../enclosure
--w------- 1 root root 4096 2008-02-03 15:44 uevent

And the individual occupied slots like this:

sparkweed:~# ls -l /sys/class/enclosure/0\:0\:1\:0/SLOT\ 001/
total 0
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 active
lrwxrwxrwx 1 root root    0 2008-02-03 15:45 device -> ../../../../devices/pci0000:01/0000:01:02.0/host0/port-0:0/expander-0:0/port-0:0:11/end_device-0:0:11/target0:0:0/0:0:0:0
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 fault
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 locate
-rw-r--r-- 1 root root 4096 2008-02-03 15:45 status
lrwxrwxrwx 1 root root    0 2008-02-03 15:45 subsystem -> ../../../enclosure_component
-r--r--r-- 1 root root 4096 2008-02-03 15:45 type
--w------- 1 root root 4096 2008-02-03 15:45 uevent

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
delete                        ioerr_cnt      rev                  type
device_blocked                iorequest_cnt  scsi_device:0:0:0:0  uevent
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] 53c7xx: kill driver · 565bae6a
      由 Christoph Hellwig 提交于 
      It's been more than enough time now to try to get the new m68k drivers
into the tree.  Let's remove the old ones and we can remerge the new
glue once it's ready.  Given that there are patches to rename two out
of the three drivers in m68k CVS and all of them need a lot of
codingstyle love anyway that's probably the better strategy to begin
with.

      [SCSI] SUNESP: Complete driver rewrite to version 2.0 · cd9ad58d
      由 David S. Miller 提交于 
      Major features:

1) Tagged queuing support.
2) Will properly negotiate for synchronous transfers even on
   devices that reject the wide negotiation message, such as
   CDROMs
3) Significantly lower kernel stack usage in interrupt
   handler path by elimination of function vector arrays,
   replaced by a top-level switch statement state machine.
4) Uses generic scsi infrastructure as much as possible to
   avoid code duplication.
5) Automatic request of sense data in response to CHECK_CONDITION
6) Portable to other platforms using ESP such as DEC and Sun3
   systems.

      [SCSI] Add ability to scan scsi busses asynchronously · 3e082a91
      由 Matthew Wilcox 提交于 
      Since it often takes around 20-30 seconds to scan a scsi bus, it's
highly advantageous to do this in parallel with other things.  The bulk
of this patch is ensuring that devices don't change numbering, and that
all devices are discovered prior to trying to start init.  For those
who build SCSI as modules, there's a new scsi_wait_scan module that will
ensure all bus scans are finished.

This patch only handles drivers which call scsi_scan_host.  Fibre Channel,
SAS, SATA, USB and Firewire all need additional work.
