Customizing OPP for platform
============================
Defining CONFIG_PM should enable OPP layer for the silicon
and the registration of OPP table should take place automatically.
However, in special cases, the default OPP table may need to be
tweaked, for e.g.:
* enable default OPPs which are disabled by default, but which
could be enabled on a platform
* Disable an unsupported OPP on the platform
* Define and add a custom opp table entry
in these cases, the board file needs to do additional steps as follows:
arch/arm/mach-omapx/board-xyz.c
#include "pm.h"
....
static void __init omap_xyz_init_irq(void)
{
....
/* Initialize the default table */
omapx_opp_init();
/* Do customization to the defaults */
....
}
NOTE: omapx_opp_init will be omap3_opp_init or as required
based on the omap family.

What: Video4Linux API 1 ioctls and from Video devices.
When: kernel 2.6.38
Files: include/linux/videodev.h
Check: include/linux/videodev.h
Why: V4L1 AP1 was replaced by V4L2 API during migration from 2.4 to 2.6
series. The old API have lots of drawbacks and don't provide enough
means to work with all video and audio standards. The newer API is
already available on the main drivers and should be used instead.
Newer drivers should use v4l_compat_translate_ioctl function to handle
old calls, replacing to newer ones.
Decoder iocts are using internally to allow video drivers to
communicate with video decoders. This should also be improved to allow
V4L2 calls being translated into compatible internal ioctls.
Compatibility ioctls will be provided, for a while, via
v4l1-compat module.

Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.

What: Video4Linux: Remove obsolete ioctl's
When: kernel 2.6.39
Files: include/media/videodev2.h
Why: Some ioctl's were defined wrong on 2.6.2 and 2.6.6, using the wrong
type of R/W arguments. They were fixed, but the old ioctl names are
still there, maintained to avoid breaking binary compatibility:
#define VIDIOC_OVERLAY_OLD _IOWR('V', 14, int)
#define VIDIOC_S_PARM_OLD _IOW('V', 22, struct v4l2_streamparm)
#define VIDIOC_S_CTRL_OLD _IOW('V', 28, struct v4l2_control)
#define VIDIOC_G_AUDIO_OLD _IOWR('V', 33, struct v4l2_audio)
#define VIDIOC_G_AUDOUT_OLD _IOWR('V', 49, struct v4l2_audioout)
#define VIDIOC_CROPCAP_OLD _IOR('V', 58, struct v4l2_cropcap)
There's no sense on preserving those forever, as it is very doubtful
that someone would try to use a such old binary with a modern kernel.
Removing them will allow us to remove some magic done at the V4L ioctl
handler.

RCU-based dcache locking model
==============================
On many workloads, the most common operation on dcache is to look up a
dentry, given a parent dentry and the name of the child. Typically,
for every open(), stat() etc., the dentry corresponding to the
pathname will be looked up by walking the tree starting with the first
component of the pathname and using that dentry along with the next
component to look up the next level and so on. Since it is a frequent
operation for workloads like multiuser environments and web servers,
it is important to optimize this path.
Prior to 2.5.10, dcache_lock was acquired in d_lookup and thus in
every component during path look-up. Since 2.5.10 onwards, fast-walk
algorithm changed this by holding the dcache_lock at the beginning and
walking as many cached path component dentries as possible. This
significantly decreases the number of acquisition of
dcache_lock. However it also increases the lock hold time
significantly and affects performance in large SMP machines. Since
2.5.62 kernel, dcache has been using a new locking model that uses RCU
to make dcache look-up lock-free.
The current dcache locking model is not very different from the
existing dcache locking model. Prior to 2.5.62 kernel, dcache_lock
protected the hash chain, d_child, d_alias, d_lru lists as well as
d_inode and several other things like mount look-up. RCU-based changes
affect only the way the hash chain is protected. For everything else
the dcache_lock must be taken for both traversing as well as
updating. The hash chain updates too take the dcache_lock. The
significant change is the way d_lookup traverses the hash chain, it
doesn't acquire the dcache_lock for this and rely on RCU to ensure
that the dentry has not been *freed*.
Dcache locking details
======================
For many multi-user workloads, open() and stat() on files are very
frequently occurring operations. Both involve walking of path names to
find the dentry corresponding to the concerned file. In 2.4 kernel,
dcache_lock was held during look-up of each path component. Contention
and cache-line bouncing of this global lock caused significant
scalability problems. With the introduction of RCU in Linux kernel,
this was worked around by making the look-up of path components during
path walking lock-free.
Safe lock-free look-up of dcache hash table
===========================================
Dcache is a complex data structure with the hash table entries also
linked together in other lists. In 2.4 kernel, dcache_lock protected
all the lists. We applied RCU only on hash chain walking. The rest of
the lists are still protected by dcache_lock. Some of the important
changes are :
1. The deletion from hash chain is done using hlist_del_rcu() macro
which doesn't initialize next pointer of the deleted dentry and
this allows us to walk safely lock-free while a deletion is
happening.
2. Insertion of a dentry into the hash table is done using
hlist_add_head_rcu() which take care of ordering the writes - the
writes to the dentry must be visible before the dentry is
inserted. This works in conjunction with hlist_for_each_rcu(),
which has since been replaced by hlist_for_each_entry_rcu(), while
walking the hash chain. The only requirement is that all
initialization to the dentry must be done before
hlist_add_head_rcu() since we don't have dcache_lock protection
while traversing the hash chain. This isn't different from the
existing code.
3. The dentry looked up without holding dcache_lock by cannot be
returned for walking if it is unhashed. It then may have a NULL
d_inode or other bogosity since RCU doesn't protect the other
fields in the dentry. We therefore use a flag DCACHE_UNHASHED to
indicate unhashed dentries and use this in conjunction with a
per-dentry lock (d_lock). Once looked up without the dcache_lock,
we acquire the per-dentry lock (d_lock) and check if the dentry is
unhashed. If so, the look-up is failed. If not, the reference count
of the dentry is increased and the dentry is returned.
4. Once a dentry is looked up, it must be ensured during the path walk
for that component it doesn't go away. In pre-2.5.10 code, this was
done holding a reference to the dentry. dcache_rcu does the same.
In some sense, dcache_rcu path walking looks like the pre-2.5.10
version.
5. All dentry hash chain updates must take the dcache_lock as well as
the per-dentry lock in that order. dput() does this to ensure that
a dentry that has just been looked up in another CPU doesn't get
deleted before dget() can be done on it.
6. There are several ways to do reference counting of RCU protected
objects. One such example is in ipv4 route cache where deferred
freeing (using call_rcu()) is done as soon as the reference count
goes to zero. This cannot be done in the case of dentries because
tearing down of dentries require blocking (dentry_iput()) which
isn't supported from RCU callbacks. Instead, tearing down of
dentries happen synchronously in dput(), but actual freeing happens
later when RCU grace period is over. This allows safe lock-free
walking of the hash chains, but a matched dentry may have been
partially torn down. The checking of DCACHE_UNHASHED flag with
d_lock held detects such dentries and prevents them from being
returned from look-up.
Maintaining POSIX rename semantics
==================================
Since look-up of dentries is lock-free, it can race against a
concurrent rename operation. For example, during rename of file A to
B, look-up of either A or B must succeed. So, if look-up of B happens
after A has been removed from the hash chain but not added to the new
hash chain, it may fail. Also, a comparison while the name is being
written concurrently by a rename may result in false positive matches
violating rename semantics. Issues related to race with rename are
handled as described below :
1. Look-up can be done in two ways - d_lookup() which is safe from
simultaneous renames and __d_lookup() which is not. If
__d_lookup() fails, it must be followed up by a d_lookup() to
correctly determine whether a dentry is in the hash table or
not. d_lookup() protects look-ups using a sequence lock
(rename_lock).
2. The name associated with a dentry (d_name) may be changed if a
rename is allowed to happen simultaneously. To avoid memcmp() in
__d_lookup() go out of bounds due to a rename and false positive
comparison, the name comparison is done while holding the
per-dentry lock. This prevents concurrent renames during this
operation.
3. Hash table walking during look-up may move to a different bucket as
the current dentry is moved to a different bucket due to rename.
But we use hlists in dcache hash table and they are
null-terminated. So, even if a dentry moves to a different bucket,
hash chain walk will terminate. [with a list_head list, it may not
since termination is when the list_head in the original bucket is
reached]. Since we redo the d_parent check and compare name while
holding d_lock, lock-free look-up will not race against d_move().
4. There can be a theoretical race when a dentry keeps coming back to
original bucket due to double moves. Due to this look-up may
consider that it has never moved and can end up in a infinite loop.
But this is not any worse that theoretical livelocks we already
have in the kernel.
Important guidelines for filesystem developers related to dcache_rcu
====================================================================
1. Existing dcache interfaces (pre-2.5.62) exported to filesystem
don't change. Only dcache internal implementation changes. However
filesystems *must not* delete from the dentry hash chains directly
using the list macros like allowed earlier. They must use dcache
APIs like d_drop() or __d_drop() depending on the situation.
2. d_flags is now protected by a per-dentry lock (d_lock). All access
to d_flags must be protected by it.
3. For a hashed dentry, checking of d_count needs to be protected by
d_lock.

Path walking and name lookup locking
====================================
Path resolution is the finding a dentry corresponding to a path name string, by
performing a path walk. Typically, for every open(), stat() etc., the path name
will be resolved. Paths are resolved by walking the namespace tree, starting
with the first component of the pathname (eg. root or cwd) with a known dentry,
then finding the child of that dentry, which is named the next component in the
path string. Then repeating the lookup from the child dentry and finding its
child with the next element, and so on.
Since it is a frequent operation for workloads like multiuser environments and
web servers, it is important to optimize this code.
Path walking synchronisation history:
Prior to 2.5.10, dcache_lock was acquired in d_lookup (dcache hash lookup) and
thus in every component during path look-up. Since 2.5.10 onwards, fast-walk
algorithm changed this by holding the dcache_lock at the beginning and walking
as many cached path component dentries as possible. This significantly
decreases the number of acquisition of dcache_lock. However it also increases
the lock hold time significantly and affects performance in large SMP machines.
Since 2.5.62 kernel, dcache has been using a new locking model that uses RCU to
make dcache look-up lock-free.
All the above algorithms required taking a lock and reference count on the
dentry that was looked up, so that may be used as the basis for walking the
next path element. This is inefficient and unscalable. It is inefficient
because of the locks and atomic operations required for every dentry element
slows things down. It is not scalable because many parallel applications that
are path-walk intensive tend to do path lookups starting from a common dentry
(usually, the root "/" or current working directory). So contention on these
common path elements causes lock and cacheline queueing.
Since 2.6.38, RCU is used to make a significant part of the entire path walk
(including dcache look-up) completely "store-free" (so, no locks, atomics, or
even stores into cachelines of common dentries). This is known as "rcu-walk"
path walking.
Path walking overview
=====================
A name string specifies a start (root directory, cwd, fd-relative) and a
sequence of elements (directory entry names), which together refer to a path in
the namespace. A path is represented as a (dentry, vfsmount) tuple. The name
elements are sub-strings, seperated by '/'.
Name lookups will want to find a particular path that a name string refers to
(usually the final element, or parent of final element). This is done by taking
the path given by the name's starting point (which we know in advance -- eg.
current->fs->cwd or current->fs->root) as the first parent of the lookup. Then
iteratively for each subsequent name element, look up the child of the current
parent with the given name and if it is not the desired entry, make it the
parent for the next lookup.
A parent, of course, must be a directory, and we must have appropriate
permissions on the parent inode to be able to walk into it.
Turning the child into a parent for the next lookup requires more checks and
procedures. Symlinks essentially substitute the symlink name for the target
name in the name string, and require some recursive path walking. Mount points
must be followed into (thus changing the vfsmount that subsequent path elements
refer to), switching from the mount point path to the root of the particular
mounted vfsmount. These behaviours are variously modified depending on the
exact path walking flags.
Path walking then must, broadly, do several particular things:
- find the start point of the walk;
- perform permissions and validity checks on inodes;
- perform dcache hash name lookups on (parent, name element) tuples;
- traverse mount points;
- traverse symlinks;
- lookup and create missing parts of the path on demand.
Safe store-free look-up of dcache hash table
============================================
Dcache name lookup
------------------
In order to lookup a dcache (parent, name) tuple, we take a hash on the tuple
and use that to select a bucket in the dcache-hash table. The list of entries
in that bucket is then walked, and we do a full comparison of each entry
against our (parent, name) tuple.
The hash lists are RCU protected, so list walking is not serialised with
concurrent updates (insertion, deletion from the hash). This is a standard RCU
list application with the exception of renames, which will be covered below.
Parent and name members of a dentry, as well as its membership in the dcache
hash, and its inode are protected by the per-dentry d_lock spinlock. A
reference is taken on the dentry (while the fields are verified under d_lock),
and this stabilises its d_inode pointer and actual inode. This gives a stable
point to perform the next step of our path walk against.
These members are also protected by d_seq seqlock, although this offers
read-only protection and no durability of results, so care must be taken when
using d_seq for synchronisation (see seqcount based lookups, below).
Renames
-------
Back to the rename case. In usual RCU protected lists, the only operations that
will happen to an object is insertion, and then eventually removal from the
list. The object will not be reused until an RCU grace period is complete.
This ensures the RCU list traversal primitives can run over the object without
problems (see RCU documentation for how this works).
However when a dentry is renamed, its hash value can change, requiring it to be
moved to a new hash list. Allocating and inserting a new alias would be
expensive and also problematic for directory dentries. Latency would be far to
high to wait for a grace period after removing the dentry and before inserting
it in the new hash bucket. So what is done is to insert the dentry into the
new list immediately.
However, when the dentry's list pointers are updated to point to objects in the
new list before waiting for a grace period, this can result in a concurrent RCU
lookup of the old list veering off into the new (incorrect) list and missing
the remaining dentries on the list.
There is no fundamental problem with walking down the wrong list, because the
dentry comparisons will never match. However it is fatal to miss a matching
dentry. So a seqlock is used to detect when a rename has occurred, and so the
lookup can be retried.
1 2 3
+---+ +---+ +---+
hlist-->| N-+->| N-+->| N-+->
head <--+-P |<-+-P |<-+-P |
+---+ +---+ +---+
Rename of dentry 2 may require it deleted from the above list, and inserted
into a new list. Deleting 2 gives the following list.
1 3
+---+ +---+ (don't worry, the longer pointers do not
hlist-->| N-+-------->| N-+-> impose a measurable performance overhead
head <--+-P |<--------+-P | on modern CPUs)
+---+ +---+
^ 2 ^
| +---+ |
| | N-+----+
+----+-P |
+---+
This is a standard RCU-list deletion, which leaves the deleted object's
pointers intact, so a concurrent list walker that is currently looking at
object 2 will correctly continue to object 3 when it is time to traverse the
next object.
However, when inserting object 2 onto a new list, we end up with this:
1 3
+---+ +---+
hlist-->| N-+-------->| N-+->
head <--+-P |<--------+-P |
+---+ +---+
2
+---+
| N-+---->
<----+-P |
+---+
Because we didn't wait for a grace period, there may be a concurrent lookup
still at 2. Now when it follows 2's 'next' pointer, it will walk off into
another list without ever having checked object 3.
A related, but distinctly different, issue is that of rename atomicity versus
lookup operations. If a file is renamed from 'A' to 'B', a lookup must only
find either 'A' or 'B'. So if a lookup of 'A' returns NULL, a subsequent lookup
of 'B' must succeed (note the reverse is not true).
Between deleting the dentry from the old hash list, and inserting it on the new
hash list, a lookup may find neither 'A' nor 'B' matching the dentry. The same
rename seqlock is also used to cover this race in much the same way, by
retrying a negative lookup result if a rename was in progress.
Seqcount based lookups
----------------------
In refcount based dcache lookups, d_lock is used to serialise access to
the dentry, stabilising it while comparing its name and parent and then
taking a reference count (the reference count then gives a stable place to
start the next part of the path walk from).
As explained above, we would like to do path walking without taking locks or
reference counts on intermediate dentries along the path. To do this, a per
dentry seqlock (d_seq) is used to take a "coherent snapshot" of what the dentry
looks like (its name, parent, and inode). That snapshot is then used to start
the next part of the path walk. When loading the coherent snapshot under d_seq,
care must be taken to load the members up-front, and use those pointers rather
than reloading from the dentry later on (otherwise we'd have interesting things
like d_inode going NULL underneath us, if the name was unlinked).
Also important is to avoid performing any destructive operations (pretty much:
no non-atomic stores to shared data), and to recheck the seqcount when we are
"done" with the operation. Retry or abort if the seqcount does not match.
Avoiding destructive or changing operations means we can easily unwind from
failure.
What this means is that a caller, provided they are holding RCU lock to
protect the dentry object from disappearing, can perform a seqcount based
lookup which does not increment the refcount on the dentry or write to
it in any way. This returned dentry can be used for subsequent operations,
provided that d_seq is rechecked after that operation is complete.
Inodes are also rcu freed, so the seqcount lookup dentry's inode may also be
queried for permissions.
With this two parts of the puzzle, we can do path lookups without taking
locks or refcounts on dentry elements.
RCU-walk path walking design
============================
Path walking code now has two distinct modes, ref-walk and rcu-walk. ref-walk
is the traditional[*] way of performing dcache lookups using d_lock to
serialise concurrent modifications to the dentry and take a reference count on
it. ref-walk is simple and obvious, and may sleep, take locks, etc while path
walking is operating on each dentry. rcu-walk uses seqcount based dentry
lookups, and can perform lookup of intermediate elements without any stores to
shared data in the dentry or inode. rcu-walk can not be applied to all cases,
eg. if the filesystem must sleep or perform non trivial operations, rcu-walk
must be switched to ref-walk mode.
[*] RCU is still used for the dentry hash lookup in ref-walk, but not the full
path walk.
Where ref-walk uses a stable, refcounted ``parent'' to walk the remaining
path string, rcu-walk uses a d_seq protected snapshot. When looking up a
child of this parent snapshot, we open d_seq critical section on the child
before closing d_seq critical section on the parent. This gives an interlocking
ladder of snapshots to walk down.
proc 101
/----------------\
/ comm: "vi" \
/ fs.root: dentry0 \
\ fs.cwd: dentry2 /
\ /
\----------------/
So when vi wants to open("/home/npiggin/test.c", O_RDWR), then it will
start from current->fs->root, which is a pinned dentry. Alternatively,
"./test.c" would start from cwd; both names refer to the same path in
the context of proc101.
dentry 0
+---------------------+ rcu-walk begins here, we note d_seq, check the
| name: "/" | inode's permission, and then look up the next
| inode: 10 | path element which is "home"...
| children:"home", ...|
+---------------------+
|
dentry 1 V
+---------------------+ ... which brings us here. We find dentry1 via
| name: "home" | hash lookup, then note d_seq and compare name
| inode: 678 | string and parent pointer. When we have a match,
| children:"npiggin" | we now recheck the d_seq of dentry0. Then we
+---------------------+ check inode and look up the next element.
|
dentry2 V
+---------------------+ Note: if dentry0 is now modified, lookup is
| name: "npiggin" | not necessarily invalid, so we need only keep a
| inode: 543 | parent for d_seq verification, and grandparents
| children:"a.c", ... | can be forgotten.
+---------------------+
|
dentry3 V
+---------------------+ At this point we have our destination dentry.
| name: "a.c" | We now take its d_lock, verify d_seq of this
| inode: 14221 | dentry. If that checks out, we can increment
| children:NULL | its refcount because we're holding d_lock.
+---------------------+
Taking a refcount on a dentry from rcu-walk mode, by taking its d_lock,
re-checking its d_seq, and then incrementing its refcount is called
"dropping rcu" or dropping from rcu-walk into ref-walk mode.
It is, in some sense, a bit of a house of cards. If the seqcount check of the
parent snapshot fails, the house comes down, because we had closed the d_seq
section on the grandparent, so we have nothing left to stand on. In that case,
the path walk must be fully restarted (which we do in ref-walk mode, to avoid
live locks). It is costly to have a full restart, but fortunately they are
quite rare.
When we reach a point where sleeping is required, or a filesystem callout
requires ref-walk, then instead of restarting the walk, we attempt to drop rcu
at the last known good dentry we have. Avoiding a full restart in ref-walk in
these cases is fundamental for performance and scalability because blocking
operations such as creates and unlinks are not uncommon.
The detailed design for rcu-walk is like this:
* LOOKUP_RCU is set in nd->flags, which distinguishes rcu-walk from ref-walk.
* Take the RCU lock for the entire path walk, starting with the acquiring
of the starting path (eg. root/cwd/fd-path). So now dentry refcounts are
not required for dentry persistence.
* synchronize_rcu is called when unregistering a filesystem, so we can
access d_ops and i_ops during rcu-walk.
* Similarly take the vfsmount lock for the entire path walk. So now mnt
refcounts are not required for persistence. Also we are free to perform mount
lookups, and to assume dentry mount points and mount roots are stable up and
down the path.
* Have a per-dentry seqlock to protect the dentry name, parent, and inode,
so we can load this tuple atomically, and also check whether any of its
members have changed.
* Dentry lookups (based on parent, candidate string tuple) recheck the parent
sequence after the child is found in case anything changed in the parent
during the path walk.
* inode is also RCU protected so we can load d_inode and use the inode for
limited things.
* i_mode, i_uid, i_gid can be tested for exec permissions during path walk.
* i_op can be loaded.
* When the destination dentry is reached, drop rcu there (ie. take d_lock,
verify d_seq, increment refcount).
* If seqlock verification fails anywhere along the path, do a full restart
of the path lookup in ref-walk mode. -ECHILD tends to be used (for want of
a better errno) to signal an rcu-walk failure.
The cases where rcu-walk cannot continue are:
* NULL dentry (ie. any uncached path element)
* Following links
It may be possible eventually to make following links rcu-walk aware.
Uncached path elements will always require dropping to ref-walk mode, at the
very least because i_mutex needs to be grabbed, and objects allocated.
Final note:
"store-free" path walking is not strictly store free. We take vfsmount lock
and refcounts (both of which can be made per-cpu), and we also store to the
stack (which is essentially CPU-local), and we also have to take locks and
refcount on final dentry.
The point is that shared data, where practically possible, is not locked
or stored into. The result is massive improvements in performance and
scalability of path resolution.
Interesting statistics
======================
The following table gives rcu lookup statistics for a few simple workloads
(2s12c24t Westmere, debian non-graphical system). Ungraceful are attempts to
drop rcu that fail due to d_seq failure and requiring the entire path lookup
again. Other cases are successful rcu-drops that are required before the final
element, nodentry for missing dentry, revalidate for filesystem revalidate
routine requiring rcu drop, permission for permission check requiring drop,
and link for symlink traversal requiring drop.
rcu-lookups restart nodentry link revalidate permission
bootup 47121 0 4624 1010 10283 7852
dbench 25386793 0 6778659(26.7%) 55 549 1156
kbuild 2696672 10 64442(2.3%) 108764(4.0%) 1 1590
git diff 39605 0 28 2 0 106
vfstest 24185492 4945 708725(2.9%) 1076136(4.4%) 0 2651
What this shows is that failed rcu-walk lookups, ie. ones that are restarted
entirely with ref-walk, are quite rare. Even the "vfstest" case which
specifically has concurrent renames/mkdir/rmdir/ creat/unlink/etc to excercise
such races is not showing a huge amount of restarts.
Dropping from rcu-walk to ref-walk mean that we have encountered a dentry where
the reference count needs to be taken for some reason. This is either because
we have reached the target of the path walk, or because we have encountered a
condition that can't be resolved in rcu-walk mode. Ideally, we drop rcu-walk
only when we have reached the target dentry, so the other statistics show where
this does not happen.
Note that a graceful drop from rcu-walk mode due to something such as the
dentry not existing (which can be common) is not necessarily a failure of
rcu-walk scheme, because some elements of the path may have been walked in
rcu-walk mode. The further we get from common path elements (such as cwd or
root), the less contended the dentry is likely to be. The closer we are to
common path elements, the more likely they will exist in dentry cache.

dcache_lock is gone, replaced by fine grained locks. See fs/dcache.c

particular things. Most of the time, a filesystem only needs ->d_lock, which
protects *all* the dcache state of a given dentry.

Filesystems must RCU-free their inodes, if they can have been accessed
via rcu-walk path walk (basically, if the file can have had a path name in the
vfs namespace).
i_dentry and i_rcu share storage in a union, and the vfs expects
i_dentry to be reinitialized before it is freed, so an:
INIT_LIST_HEAD(&inode->i_dentry);
must be done in the RCU callback.

[recommended]
vfs now tries to do path walking in "rcu-walk mode", which avoids
atomic operations and scalability hazards on dentries and inodes (see
Documentation/filesystems/path-walk.txt). d_hash and d_compare changes (above)
are examples of the changes required to support this. For more complex
filesystem callbacks, the vfs drops out of rcu-walk mode before the fs call, so
no changes are required to the filesystem. However, this is costly and loses
the benefits of rcu-walk mode. We will begin to add filesystem callbacks that
are rcu-walk aware, shown below. Filesystems should take advantage of this
where possible.
--
[mandatory]
d_revalidate is a callback that is made on every path element (if
the filesystem provides it), which requires dropping out of rcu-walk mode. This
may now be called in rcu-walk mode (nd->flags & LOOKUP_RCU). -ECHILD should be
returned if the filesystem cannot handle rcu-walk. See
Documentation/filesystems/vfs.txt for more details.
permission and check_acl are inode permission checks that are called
on many or all directory inodes on the way down a path walk (to check for
exec permission). These must now be rcu-walk aware (flags & IPERM_RCU). See

Kernel driver ds620
===================
Supported chips:
* Dallas Semiconductor DS620
Prefix: 'ds620'
Datasheet: Publicly available at the Dallas Semiconductor website
http://www.dalsemi.com/
Authors:
Roland Stigge <stigge@antcom.de>
based on ds1621.c by
Christian W. Zuckschwerdt <zany@triq.net>
Description
-----------
The DS620 is a (one instance) digital thermometer and thermostat. It has both
high and low temperature limits which can be user defined (i.e. programmed
into non-volatile on-chip registers). Temperature range is -55 degree Celsius
to +125. Between 0 and 70 degree Celsius, accuracy is 0.5 Kelvin. The value
returned via sysfs displays post decimal positions.
The thermostat function works as follows: When configured via platform_data
(struct ds620_platform_data) .pomode == 0 (default), the thermostat output pin
PO is always low. If .pomode == 1, the thermostat is in PO_LOW mode. I.e., the
output pin PO becomes active when the temperature falls below temp1_min and
stays active until the temperature goes above temp1_max.
Likewise, with .pomode == 2, the thermostat is in PO_HIGH mode. I.e., the PO
output pin becomes active when the temperature goes above temp1_max and stays
active until the temperature falls below temp1_min.
The PO output pin of the DS620 operates active-low.

Author:
Urs Fleisch <urs.fleisch@sensirion.com>
Description
-----------
The SHT21 and SHT25 are humidity and temperature sensors in a DFN package of
only 3 x 3 mm footprint and 1.1 mm height. The difference between the two
devices is the higher level of precision of the SHT25 (1.8% relative humidity,
0.2 degree Celsius) compared with the SHT21 (2.0% relative humidity,
0.3 degree Celsius).
The devices communicate with the I2C protocol. All sensors are set to the same
I2C address 0x40, so an entry with I2C_BOARD_INFO("sht21", 0x40) can be used
in the board setup code.
sysfs-Interface
---------------
temp1_input - temperature input
humidity1_input - humidity input
Notes
-----
The driver uses the default resolution settings of 12 bit for humidity and 14
bit for temperature, which results in typical measurement times of 22 ms for
humidity and 66 ms for temperature. To keep self heating below 0.1 degree
Celsius, the device should not be active for more than 10% of the time,
e.g. maximum two measurements per second at the given resolution.
Different resolutions, the on-chip heater, using the CRC checksum and reading
the serial number are not supported yet.

Description
-----------
CMA3000 Tri-axis accelerometer supports Motion detect, Measurement and
Free fall modes.
Motion Detect Mode: Its the low power mode where interrupts are generated only
when motion exceeds the defined thresholds.
Measurement Mode: This mode is used to read the acceleration data on X,Y,Z
axis and supports 400, 100, 40 Hz sample frequency.
Free fall Mode: This mode is intended to save system resources.
Threshold values: Chip supports defining threshold values for above modes
which includes time and g value. Refer product specifications for more details.
CMA3000 chip supports mutually exclusive I2C and SPI interfaces for
communication, currently the driver supports I2C based communication only.
Initial configuration for bus mode is set in non volatile memory and can later
be modified through bus interface command.
Driver reports acceleration data through input subsystem. It generates ABS_MISC
event with value 1 when free fall is detected.
Platform data need to be configured for initial default values.

Trusted and Encrypted Keys
Trusted and Encrypted Keys are two new key types added to the existing kernel
key ring service. Both of these new types are variable length symmetic keys,
and in both cases all keys are created in the kernel, and user space sees,
stores, and loads only encrypted blobs. Trusted Keys require the availability
of a Trusted Platform Module (TPM) chip for greater security, while Encrypted
Keys can be used on any system. All user level blobs, are displayed and loaded
in hex ascii for convenience, and are integrity verified.
Trusted Keys use a TPM both to generate and to seal the keys. Keys are sealed
under a 2048 bit RSA key in the TPM, and optionally sealed to specified PCR
(integrity measurement) values, and only unsealed by the TPM, if PCRs and blob
integrity verifications match. A loaded Trusted Key can be updated with new
(future) PCR values, so keys are easily migrated to new pcr values, such as
when the kernel and initramfs are updated. The same key can have many saved
blobs under different PCR values, so multiple boots are easily supported.
By default, trusted keys are sealed under the SRK, which has the default
authorization value (20 zeros). This can be set at takeownership time with the
trouser's utility: "tpm_takeownership -u -z".
Usage:
keyctl add trusted name "new keylen [options]" ring
keyctl add trusted name "load hex_blob [pcrlock=pcrnum]" ring
keyctl update key "update [options]"
keyctl print keyid
options:
keyhandle= ascii hex value of sealing key default 0x40000000 (SRK)
keyauth= ascii hex auth for sealing key default 0x00...i
(40 ascii zeros)
blobauth= ascii hex auth for sealed data default 0x00...
(40 ascii zeros)
blobauth= ascii hex auth for sealed data default 0x00...
(40 ascii zeros)
pcrinfo= ascii hex of PCR_INFO or PCR_INFO_LONG (no default)
pcrlock= pcr number to be extended to "lock" blob
migratable= 0|1 indicating permission to reseal to new PCR values,
default 1 (resealing allowed)
"keyctl print" returns an ascii hex copy of the sealed key, which is in standard
TPM_STORED_DATA format. The key length for new keys are always in bytes.
Trusted Keys can be 32 - 128 bytes (256 - 1024 bits), the upper limit is to fit
within the 2048 bit SRK (RSA) keylength, with all necessary structure/padding.
Encrypted keys do not depend on a TPM, and are faster, as they use AES for
encryption/decryption. New keys are created from kernel generated random
numbers, and are encrypted/decrypted using a specified 'master' key. The
'master' key can either be a trusted-key or user-key type. The main
disadvantage of encrypted keys is that if they are not rooted in a trusted key,
they are only as secure as the user key encrypting them. The master user key
should therefore be loaded in as secure a way as possible, preferably early in
boot.
Usage:
keyctl add encrypted name "new key-type:master-key-name keylen" ring
keyctl add encrypted name "load hex_blob" ring
keyctl update keyid "update key-type:master-key-name"
where 'key-type' is either 'trusted' or 'user'.

The initial consumer of trusted keys is EVM, which at boot time needs a high
quality symmetric key for HMAC protection of file metadata. The use of a
trusted key provides strong guarantees that the EVM key has not been
compromised by a user level problem, and when sealed to specific boot PCR
values, protects against boot and offline attacks. Other uses for trusted and
encrypted keys, such as for disk and file encryption are anticipated.

RS485 SERIAL COMMUNICATIONS
1. INTRODUCTION
EIA-485, also known as TIA/EIA-485 or RS-485, is a standard defining the
electrical characteristics of drivers and receivers for use in balanced
digital multipoint systems.
This standard is widely used for communications in industrial automation
because it can be used effectively over long distances and in electrically
noisy environments.
2. HARDWARE-RELATED CONSIDERATIONS
Some CPUs/UARTs (e.g., Atmel AT91 or 16C950 UART) contain a built-in
half-duplex mode capable of automatically controlling line direction by
toggling RTS or DTR signals. That can be used to control external
half-duplex hardware like an RS485 transceiver or any RS232-connected
half-duplex devices like some modems.
For these microcontrollers, the Linux driver should be made capable of
working in both modes, and proper ioctls (see later) should be made
available at user-level to allow switching from one mode to the other, and
vice versa.
3. DATA STRUCTURES ALREADY AVAILABLE IN THE KERNEL
The Linux kernel provides the serial_rs485 structure (see [1]) to handle
RS485 communications. This data structure is used to set and configure RS485
parameters in the platform data and in ioctls.
Any driver for devices capable of working both as RS232 and RS485 should
provide at least the following ioctls:
- TIOCSRS485 (typically associated with number 0x542F). This ioctl is used
to enable/disable RS485 mode from user-space
- TIOCGRS485 (typically associated with number 0x542E). This ioctl is used
to get RS485 mode from kernel-space (i.e., driver) to user-space.
In other words, the serial driver should contain a code similar to the next
one:
static struct uart_ops atmel_pops = {
/* ... */
.ioctl = handle_ioctl,
};
static int handle_ioctl(struct uart_port *port,
unsigned int cmd,
unsigned long arg)
{
struct serial_rs485 rs485conf;
switch (cmd) {
case TIOCSRS485:
if (copy_from_user(&rs485conf,
(struct serial_rs485 *) arg,
sizeof(rs485conf)))
return -EFAULT;
/* ... */
break;
case TIOCGRS485:
if (copy_to_user((struct serial_rs485 *) arg,
...,
sizeof(rs485conf)))
return -EFAULT;
/* ... */
break;
/* ... */
}
}
4. USAGE FROM USER-LEVEL
From user-level, RS485 configuration can be get/set using the previous
ioctls. For instance, to set RS485 you can use the following code:
#include <linux/serial.h>
/* Driver-specific ioctls: */
#define TIOCGRS485 0x542E
#define TIOCSRS485 0x542F
/* Open your specific device (e.g., /dev/mydevice): */
int fd = open ("/dev/mydevice", O_RDWR);
if (fd < 0) {
/* Error handling. See errno. */
}
struct serial_rs485 rs485conf;
/* Set RS485 mode: */
rs485conf.flags |= SER_RS485_ENABLED;
/* Set rts delay before send, if needed: */
rs485conf.flags |= SER_RS485_RTS_BEFORE_SEND;
rs485conf.delay_rts_before_send = ...;
/* Set rts delay after send, if needed: */
rs485conf.flags |= SER_RS485_RTS_AFTER_SEND;
rs485conf.delay_rts_after_send = ...;
if (ioctl (fd, TIOCSRS485, &rs485conf) < 0) {
/* Error handling. See errno. */
}
/* Use read() and write() syscalls here... */
/* Close the device when finished: */
if (close (fd) < 0) {
/* Error handling. See errno. */
}

This is a driver for the CPiA PPC2 driven parallel connected
Camera. For example the Creative WebcamII is CPiA driven.
) [1]Peter Pregler, Linz 2000, published under the [2]GNU GPL
---------------------------------------------------------------------------
USAGE:
General:
========
1) Make sure you have created the video devices (/dev/video*):
- if you have a recent MAKEDEV do a 'cd /dev;./MAKEDEV video'
- otherwise do a:
cd /dev
mknod video0 c 81 0
ln -s video0 video
2) Compile the kernel (see below for the list of options to use),
configure your parport and reboot.
3) If all worked well you should get messages similar
to the following (your versions may be different) on the console:
V4L-Driver for Vision CPiA based cameras v0.7.4
parport0: read2 timeout.
parport0: Multimedia device, VLSI Vision Ltd PPC2
Parallel port driver for Vision CPiA based camera
CPIA Version: 1.20 (2.0)
CPIA PnP-ID: 0553:0002:0100
VP-Version: 1.0 0100
1 camera(s) found
As modules:
===========
Make sure you have selected the following kernel options (you can
select all stuff as modules):
The cpia-stuff is in the section 'Character devices -> Video For Linux'.
CONFIG_PARPORT=m
CONFIG_PARPORT_PC=m
CONFIG_PARPORT_PC_FIFO=y
CONFIG_PARPORT_1284=y
CONFIG_VIDEO_DEV=m
CONFIG_VIDEO_CPIA=m
CONFIG_VIDEO_CPIA_PP=m
For autoloading of all those modules you need to tell module-init-tools
some stuff. Add the following line to your module-init-tools config-file
(e.g. /etc/modprobe.conf or wherever your distribution does store that
stuff):
options parport_pc io=0x378 irq=7 dma=3
alias char-major-81 cpia_pp
The first line tells the dma/irq channels to use. Those _must_ match
the settings of your BIOS. Do NOT simply use the values above. See
Documentation/parport.txt for more information about this. The second
line associates the video-device file with the driver. Of cause you
can also load the modules once upon boot (usually done in /etc/modules).
Linked into the kernel:
=======================
Make sure you have selected the following kernel options. Note that
you cannot compile the parport-stuff as modules and the cpia-driver
statically (the other way round is okay though).
The cpia-stuff is in the section 'Character devices -> Video For Linux'.
CONFIG_PARPORT=y
CONFIG_PARPORT_PC=y
CONFIG_PARPORT_PC_FIFO=y
CONFIG_PARPORT_1284=y
CONFIG_VIDEO_DEV=y
CONFIG_VIDEO_CPIA=y
CONFIG_VIDEO_CPIA_PP=y
To use DMA/irq you will need to tell the kernel upon boot time the
hardware configuration of the parport. You can give the boot-parameter
at the LILO-prompt or specify it in lilo.conf. I use the following
append-line in lilo.conf:
append="parport=0x378,7,3"
See Documentation/parport.txt for more information about the
configuration of the parport and the values given above. Do not simply
use the values given above.
---------------------------------------------------------------------------
FEATURES:
- mmap/read v4l-interface (but no overlay)
- image formats: CIF/QCIF, SIF/QSIF, various others used by isabel;
note: all sizes except CIF/QCIF are implemented by clipping, i.e.
pixels are not uploaded from the camera
- palettes: VIDEO_PALETTE_GRAY, VIDEO_PALETTE_RGB565, VIDEO_PALETTE_RGB555,
VIDEO_PALETTE_RGB24, VIDEO_PALETTE_RGB32, VIDEO_PALETTE_YUYV,
VIDEO_PALETTE_UYVY, VIDEO_PALETTE_YUV422
- state information (color balance, exposure, ...) is preserved between
device opens
- complete control over camera via proc-interface (_all_ camera settings are
supported), there is also a python-gtk application available for this [3]
- works under SMP (but the driver is completely serialized and synchronous)
so you get no benefit from SMP, but at least it does not crash your box
- might work for non-Intel architecture, let us know about this
---------------------------------------------------------------------------
TESTED APPLICATIONS:
- a simple test application based on Xt is available at [3]
- another test-application based on gqcam-0.4 (uses GTK)
- gqcam-0.6 should work
- xawtv-3.x (also the webcam software)
- xawtv-2.46
- w3cam (cgi-interface and vidcat, e.g. you may try out 'vidcat |xv
-maxpect -root -quit +noresetroot -rmode 5 -')
- vic, the MBONE video conferencing tool (version 2.8ucl4-1)
- isabel 3R4beta (barely working, but AFAICT all the problems are on
their side)
- camserv-0.40
See [3] for pointers to v4l-applications.
---------------------------------------------------------------------------
KNOWN PROBLEMS:
- some applications do not handle the image format correctly, you will
see strange horizontal stripes instead of a nice picture -> make sure
your application does use a supported image size or queries the driver
for the actually used size (reason behind this: the camera cannot
provide any image format, so if size NxM is requested the driver will
use a format to the closest fitting N1xM1, the application should now
query for this granted size, most applications do not).
- all the todo ;)
- if there is not enough light and the picture is too dark try to
adjust the SetSensorFPS setting, automatic frame rate adjustment
has its price
- do not try out isabel 3R4beta (built 135), you will be disappointed
---------------------------------------------------------------------------
TODO:
- multiple camera support (struct camera or something) - This should work,
but hasn't been tested yet.
- architecture independence?
- SMP-safe asynchronous mmap interface
- nibble mode for old parport interfaces
- streaming capture, this should give a performance gain
---------------------------------------------------------------------------
IMPLEMENTATION NOTES:
The camera can act in two modes, streaming or grabbing. Right now a
polling grab-scheme is used. Maybe interrupt driven streaming will be
used for a asynchronous mmap interface in the next major release of the
driver. This might give a better frame rate.

4. Programming interface
This driver conforms to video4linux and video4linux2, both can be used to
use the driver. Since video4linux didn't provide adequate calls to fully
use the cards' features, we've introduced several programming extensions,
which are currently officially accepted in the 2.4.x branch of the kernel.
These extensions are known as the v4l/mjpeg extensions. See zoran.h for
details (structs/ioctls).

The ioctls for that interface are as follows:
BUZIOC_G_PARAMS
BUZIOC_S_PARAMS
Get and set the parameters of the buz. The user should always do a
BUZIOC_G_PARAMS (with a struct buz_params) to obtain the default
settings, change what he likes and then make a BUZIOC_S_PARAMS call.
BUZIOC_REQBUFS
Before being able to capture/playback, the user has to request
the buffers he is wanting to use. Fill the structure
zoran_requestbuffers with the size (recommended: 256*1024) and
the number (recommended 32 up to 256). There are no such restrictions
as for the Video for Linux buffers, you should LEAVE SUFFICIENT
MEMORY for your system however, else strange things will happen ....
On return, the zoran_requestbuffers structure contains number and
size of the actually allocated buffers.
You should use these numbers for doing a mmap of the buffers
into the user space.
The BUZIOC_REQBUFS ioctl also makes it happen, that the next mmap
maps the MJPEG buffer instead of the V4L buffers.
BUZIOC_QBUF_CAPT
BUZIOC_QBUF_PLAY
Queue a buffer for capture or playback. The first call also starts
streaming capture. When streaming capture is going on, you may
only queue further buffers or issue syncs until streaming
capture is switched off again with a argument of -1 to
a BUZIOC_QBUF_CAPT/BUZIOC_QBUF_PLAY ioctl.
BUZIOC_SYNC
Issue this ioctl when all buffers are queued. This ioctl will
block until the first buffer becomes free for saving its
data to disk (after BUZIOC_QBUF_CAPT) or for reuse (after BUZIOC_QBUF_PLAY).
BUZIOC_G_STATUS
Get the status of the input lines (video source connected/norm).
This driver conforms to video4linux2. Support for V4L1 and for the custom
zoran ioctls has been removed in kernel 2.6.38.
For programming example, please, look at lavrec.c and lavplay.c code in

The vidioc_streamon() and vidioc_streamoff() functions will be a bit more
