+What: /sys/firmware/sgi_uv/
+Date: August 2008
+Contact: Russ Anderson <rja@sgi.com>
+Description:
+ The /sys/firmware/sgi_uv directory contains information
+ about the SGI UV platform.
+
+ Under that directory are a number of files:
+
+ partition_id
+ coherence_id
+
+ The partition_id entry contains the partition id.
+ SGI UV systems can be partitioned into multiple physical
+ machines, which each partition running a unique copy
+ of the operating system. Each partition will have a unique
+ partition id. To display the partition id, use the command:
+
+ cat /sys/firmware/sgi_uv/partition_id
+
+ The coherence_id entry contains the coherence id.
+ A partitioned SGI UV system can have one or more coherence
+ domain. The coherence id indicates which coherence domain
+ this partition is in. To display the coherence id, use the
+ command:
+
+ cat /sys/firmware/sgi_uv/coherence_id

locking rules:

->get_sb() returns error or 0 with locked superblock attached to the vfsmount
(exclusive on ->s_umount).

semaphore. Note some filesystems (i.e. remote ones) provide no
protection for i_size so you will need to use the BKL.
-->open() locking is in-transit: big lock partially moved into the methods.
-The only exception is ->open() in the instances of file_operations that never
-end up in ->i_fop/->proc_fops, i.e. ones that belong to character devices
-(chrdev_open() takes lock before replacing ->f_op and calling the secondary
-method. As soon as we fix the handling of module reference counters all
-instances of ->open() will be called without the BKL.
-
Note: ext2_release() was *the* source of contention on fs-intensive
loads and dropping BKL on ->release() helps to get rid of that (we still
grab BKL for cases when we close a file that had been opened r/w, but that

There is plenty of additional information on the linux-ntfs web site
-at http://linux-ntfs.sourceforge.net/
+at http://www.linux-ntfs.org/
The web site has a lot of additional information, such as a comprehensive
FAQ, documentation on the NTFS on-disk format, information on the Linux-NTFS
For Win2k and later dynamic disks, you can for example use the ldminfo utility
which is part of the Linux LDM tools (the latest version at the time of
writing is linux-ldm-0.0.8.tar.bz2). You can download it from:
- http://linux-ntfs.sourceforge.net/downloads.html
+ http://www.linux-ntfs.org/
Simply extract the downloaded archive (tar xvjf linux-ldm-0.0.8.tar.bz2), go
into it (cd linux-ldm-0.0.8) and change to the test directory (cd test). You
will find the precompiled (i386) ldminfo utility there. NOTE: You will not be
"smaps". When enabled, the contents of these files are visible only to
readers that are allowed to ptrace() the given process.
+msgmni
+------
+
+Maximum number of message queue ids on the system.
+This value scales to the amount of lowmem. It is automatically recomputed
+upon memory add/remove or ipc namespace creation/removal.
+When a value is written into this file, msgmni's value becomes fixed, i.e. it
+is not recomputed anymore when one of the above events occurs.
+Use auto_msgmni to change this behavior.
+
+auto_msgmni
+-----------
+
+Enables/Disables automatic recomputing of msgmni upon memory add/remove or
+upon ipc namespace creation/removal (see the msgmni description above).
+Echoing "1" into this file enables msgmni automatic recomputing.
+Echoing "0" turns it off.
+auto_msgmni default value is 1.

- - Experimental: WAN enable and disable

A compatibility table by model and feature is maintained on the web
site, http://ibm-acpi.sf.net/. I appreciate any success or failure
would be the safest choice, though).

-This feature is marked EXPERIMENTAL because the implementation
-directly accesses hardware registers and may not work as expected. USE
-WITH CAUTION! To use this feature, you need to supply the
-experimental=1 parameter when loading the module.

This feature shows the presence and current state of a W-WAN (Sierra

and will allow you to use a SCSI device driver instead of a native
ATAPI driver.
- This is useful if you have an ATAPI device for which no native
- driver has been written (for example, an ATAPI PD-CD drive);
- you can then use this emulation together with an appropriate SCSI
- device driver. In order to do this, say Y here and to "SCSI support"
- and "SCSI generic support", below. You must then provide the kernel
- command line "hdx=ide-scsi" (try "man bootparam" or see the
- documentation of your boot loader (lilo or loadlin) about how to
- pass options to the kernel at boot time) for devices if you want the
- native EIDE sub-drivers to skip over the native support, so that
- this SCSI emulation can be used instead.
-
- Note that this option does NOT allow you to attach SCSI devices to a
- box that doesn't have a SCSI host adapter installed.
-
If both this SCSI emulation and native ATAPI support are compiled
into the kernel, the native support will be used.
