@ -206,16 +206,3 @@ Description:
when a discarded area is read the discard_zeroes_data
parameter will be set to one. Otherwise it will be 0 and
the result of reading a discarded area is undefined.
What: /sys/block/<disk>/alias
Date: Aug 2011
Contact: Nao Nishijima <nao.nishijima.xt@hitachi.com>
Description:
A raw device name of a disk does not always point a same disk
each boot-up time. Therefore, users have to use persistent
device names, which udev creates when the kernel finds a disk,
instead of raw device name. However, kernel doesn't show those
persistent names on its messages (e.g. dmesg).
This file can store an alias of the disk and it would be
appeared in kernel messages if it is set. A disk can have an
alias which length is up to 255bytes. Users can use alphabets,
numbers, "-" and "_" in alias name. This file is writeonce.

@ -98,14 +98,12 @@ You must enable "SCSI tape drive support for Smart Array 5xxx" and
"SCSI support" in your kernel configuration to be able to use SCSI
tape drives with your Smart Array 5xxx controller.
Additionally, note that the driver will not engage the SCSI core at init
time. The driver must be directed to dynamically engage the SCSI core via
the /proc filesystem entry which the "block" side of the driver creates as
/proc/driver/cciss/cciss* at runtime. This is because at driver init time,
the SCSI core may not yet be initialized (because the driver is a block
driver) and attempting to register it with the SCSI core in such a case
would cause a hang. This is best done via an initialization script
(typically in /etc/init.d, but could vary depending on distribution).
Additionally, note that the driver will engage the SCSI core at init
time if any tape drives or medium changers are detected. The driver may
also be directed to dynamically engage the SCSI core via the /proc filesystem
entry which the "block" side of the driver creates as
/proc/driver/cciss/cciss* at runtime. This is best done via a script.
For example:
for x in /proc/driver/cciss/cciss[0-9]*

Documentation/i2c/ten-bit-addresses
View File

@ -1,22 +1,24 @@
The I2C protocol knows about two kinds of device addresses: normal 7 bit
addresses, and an extended set of 10 bit addresses. The sets of addresses
do not intersect: the 7 bit address 0x10 is not the same as the 10 bit
address 0x10 (though a single device could respond to both of them). You
select a 10 bit address by adding an extra byte after the address
byte:
S Addr7 Rd/Wr ....
becomes
S 11110 Addr10 Rd/Wr
S is the start bit, Rd/Wr the read/write bit, and if you count the number
of bits, you will see the there are 8 after the S bit for 7 bit addresses,
and 16 after the S bit for 10 bit addresses.
address 0x10 (though a single device could respond to both of them).
WARNING! The current 10 bit address support is EXPERIMENTAL. There are
several places in the code that will cause SEVERE PROBLEMS with 10 bit
addresses, even though there is some basic handling and hooks. Also,
almost no supported adapter handles the 10 bit addresses correctly.
I2C messages to and from 10-bit address devices have a different format.
See the I2C specification for the details.
As soon as a real 10 bit address device is spotted 'in the wild', we
can and will add proper support. Right now, 10 bit address devices
are defined by the I2C protocol, but we have never seen a single device
which supports them.
The current 10 bit address support is minimal. It should work, however
you can expect some problems along the way:
* Not all bus drivers support 10-bit addresses. Some don't because the
hardware doesn't support them (SMBus doesn't require 10-bit address
support for example), some don't because nobody bothered adding the
code (or it's there but not working properly.) Software implementation
(i2c-algo-bit) is known to work.
* Some optional features do not support 10-bit addresses. This is the
case of automatic detection and instantiation of devices by their,
drivers, for example.
* Many user-space packages (for example i2c-tools) lack support for
10-bit addresses.
Note that 10-bit address devices are still pretty rare, so the limitations
listed above could stay for a long time, maybe even forever if nobody
needs them to be fixed.
