ChangeLog:

SMP IRQ affinity, started by Ingo Molnar <mingo@redhat.com>
SMP IRQ affinity
/proc/irq/IRQ#/smp_affinity specifies which target CPUs are permitted
for a given IRQ source. It's a bitmask of allowed CPUs. It's not allowed
to turn off all CPUs, and if an IRQ controller does not support IRQ
affinity then the value will not change from the default 0xffffffff.
Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting
the IRQ to CPU4-7 (this is an 8-CPU SMP box):
/proc/irq/default_smp_affinity specifies default affinity mask that applies
to all non-active IRQs. Once IRQ is allocated/activated its affinity bitmask
will be set to the default mask. It can then be changed as described above.
Default mask is 0xffffffff.
Here is an example of restricting IRQ44 (eth1) to CPU0-3 then restricting
it to CPU4-7 (this is an 8-CPU SMP box):

a. Make updates appear atomic to readers. For example,
a. Use the RCU variants of the list and hlist update

the readers refrain from accessing can be guarded by the
update-side lock.

atomic, as will individual atomic primitives. Operations

However, actually setting this config option to "y" results in the system
running the test immediately upon boot, and ending only when the system
is taken down. Normally, one will instead want to build the system
with CONFIG_RCU_TORTURE_TEST=m and to use modprobe and rmmod to control
the test, perhaps using a script similar to the one shown at the end of
this document. Note that you will need CONFIG_MODULE_UNLOAD in order

CONFIG_RCU_TORTURE_TEST_RUNNABLE
It is also possible to specify CONFIG_RCU_TORTURE_TEST=y, which will
result in the tests being loaded into the base kernel. In this case,
the CONFIG_RCU_TORTURE_TEST_RUNNABLE config option is used to specify
whether the RCU torture tests are to be started immediately during
boot or whether the /proc/sys/kernel/rcutorture_runnable file is used
to enable them. This /proc file can be used to repeatedly pause and
restart the tests, regardless of the initial state specified by the
CONFIG_RCU_TORTURE_TEST_RUNNABLE config option.
You will normally -not- want to start the RCU torture tests during boot

or grab the latest git repository from:
- mount /dev/hda1 /wherever -t ext4dev
git://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git
- To enable extents,
- Create a new filesystem using the ext4dev filesystem type:
mount /dev/hda1 /wherever -t ext4dev -o extents
# mke2fs -t ext4dev /dev/hda1
- The filesystem is compatible with the ext3 driver until you add a file
which has extents (ie: `mount -o extents', then create a file).
Or configure an existing ext3 filesystem to support extents and set
the test_fs flag to indicate that it's ok for an in-development
filesystem to touch this filesystem:
NOTE: The "extents" mount flag is temporary. It will soon go away and
extents will be enabled by the "-o extents" flag to mke2fs or tune2fs
# tune2fs -O extents -E test_fs /dev/hda1
If the filesystem was created with 128 byte inodes, it can be
converted to use 256 byte for greater efficiency via:
# tune2fs -I 256 /dev/hda1
(Note: we currently do not have tools to convert an ext4dev
filesystem back to ext3; so please do not do try this on production
filesystems.)
- Mounting:
# mount -t ext4dev /dev/hda1 /wherever
- When comparing performance with other filesystems, remember that
ext3/4 by default offers higher data integrity guarantees than most. So
when comparing with a metadata-only journalling filesystem, use `mount -o

with it. Making the journal larger than the mke2fs default often helps
performance with metadata-intensive workloads.
ext3/4 by default offers higher data integrity guarantees than most.
So when comparing with a metadata-only journalling filesystem, such
as ext3, use `mount -o data=writeback'. And you might as well use
`mount -o nobh' too along with it. Making the journal larger than
the mke2fs default often helps performance with metadata-intensive
workloads.
2. Features
===========
2.1 Currently available
* ability to use filesystems > 16TB
* ability to use filesystems > 16TB (e2fsprogs support not available yet)
* extent format reduces metadata overhead (RAM, IO for access, transactions)
* extent format more robust in face of on-disk corruption due to magics,
* internal redunancy in tree
2.1 Previously available, soon to be enabled by default by "mkefs.ext4":
* dir_index and resize inode will be on by default
* large inodes will be used by default for fast EAs, nsec timestamps, etc
* improved file allocation (multi-block alloc)
* fix 32000 subdirectory limit
* nsec timestamps for mtime, atime, ctime, create time
* inode version field on disk (NFSv4, Lustre)
* reduced e2fsck time via uninit_bg feature
* journal checksumming for robustness, performance
* persistent file preallocation (e.g for streaming media, databases)
* ability to pack bitmaps and inode tables into larger virtual groups via the
flex_bg feature
* large file support
* Inode allocation using large virtual block groups via flex_bg
* delayed allocation
* large block (up to pagesize) support
* efficent new ordered mode in JBD2 and ext4(avoid using buffer head to force
the ordering)
2.2 Candidate features for future inclusion
There are several under discussion, whether they all make it in is
partly a function of how much time everyone has to work on them:
* Online defrag (patches available but not well tested)
* reduced mke2fs time via lazy itable initialization in conjuction with
the uninit_bg feature (capability to do this is available in e2fsprogs
but a kernel thread to do lazy zeroing of unused inode table blocks
after filesystem is first mounted is required for safety)
* improved file allocation (multi-block alloc, delayed alloc; basically done)
* fix 32000 subdirectory limit (patch exists, needs some e2fsck work)
* nsec timestamps for mtime, atime, ctime, create time (patch exists,
needs some e2fsck work)
* inode version field on disk (NFSv4, Lustre; prototype exists)
* reduced mke2fs/e2fsck time via uninitialized groups (prototype exists)
* journal checksumming for robustness, performance (prototype exists)
* persistent file preallocation (e.g for streaming media, databases)
There are several others under discussion, whether they all make it in is
partly a function of how much time everyone has to work on them. Features like
metadata checksumming have been discussed and planned for a bit but no patches
exist yet so I'm not sure they're in the near-term roadmap.

The big performance win will come with mballoc, delalloc and flex_bg

The big performance win will come with mballoc and delalloc. CFS has
been using mballoc for a few years already with Lustre, and IBM + Bull
did a lot of benchmarking on it. The reason it isn't in the first set of
patches is partly a manageability issue, and partly because it doesn't
directly affect the on-disk format (outside of much better allocation)
so it isn't critical to get into the first round of changes. I believe
Alex is working on a new set of patches right now.

Glock internal locking rules
------------------------------
This documents the basic principles of the glock state machine
internals. Each glock (struct gfs2_glock in fs/gfs2/incore.h)
has two main (internal) locks:
1. A spinlock (gl_spin) which protects the internal state such
as gl_state, gl_target and the list of holders (gl_holders)
2. A non-blocking bit lock, GLF_LOCK, which is used to prevent other
threads from making calls to the DLM, etc. at the same time. If a
thread takes this lock, it must then call run_queue (usually via the
workqueue) when it releases it in order to ensure any pending tasks
are completed.
The gl_holders list contains all the queued lock requests (not
just the holders) associated with the glock. If there are any
held locks, then they will be contiguous entries at the head
of the list. Locks are granted in strictly the order that they
are queued, except for those marked LM_FLAG_PRIORITY which are
used only during recovery, and even then only for journal locks.
There are three lock states that users of the glock layer can request,
namely shared (SH), deferred (DF) and exclusive (EX). Those translate
to the following DLM lock modes:
Glock mode | DLM lock mode
------------------------------
UN | IV/NL Unlocked (no DLM lock associated with glock) or NL
SH | PR (Protected read)
DF | CW (Concurrent write)
EX | EX (Exclusive)
Thus DF is basically a shared mode which is incompatible with the "normal"
shared lock mode, SH. In GFS2 the DF mode is used exclusively for direct I/O
operations. The glocks are basically a lock plus some routines which deal
with cache management. The following rules apply for the cache:
Glock mode | Cache data | Cache Metadata | Dirty Data | Dirty Metadata
--------------------------------------------------------------------------
UN | No | No | No | No
SH | Yes | Yes | No | No
DF | No | Yes | No | No
EX | Yes | Yes | Yes | Yes
These rules are implemented using the various glock operations which
are defined for each type of glock. Not all types of glocks use
all the modes. Only inode glocks use the DF mode for example.
Table of glock operations and per type constants:
Field | Purpose
----------------------------------------------------------------------------
go_xmote_th | Called before remote state change (e.g. to sync dirty data)
go_xmote_bh | Called after remote state change (e.g. to refill cache)
go_inval | Called if remote state change requires invalidating the cache
go_demote_ok | Returns boolean value of whether its ok to demote a glock
| (e.g. checks timeout, and that there is no cached data)
go_lock | Called for the first local holder of a lock
go_unlock | Called on the final local unlock of a lock
go_dump | Called to print content of object for debugfs file, or on
| error to dump glock to the log.
go_type; | The type of the glock, LM_TYPE_.....
go_min_hold_time | The minimum hold time
The minimum hold time for each lock is the time after a remote lock
grant for which we ignore remote demote requests. This is in order to
prevent a situation where locks are being bounced around the cluster
from node to node with none of the nodes making any progress. This
tends to show up most with shared mmaped files which are being written
to by multiple nodes. By delaying the demotion in response to a
remote callback, that gives the userspace program time to make
some progress before the pages are unmapped.
There is a plan to try and remove the go_lock and go_unlock callbacks
if possible, in order to try and speed up the fast path though the locking.
Also, eventually we hope to make the glock "EX" mode locally shared
such that any local locking will be done with the i_mutex as required
rather than via the glock.
Locking rules for glock operations:
Operation | GLF_LOCK bit lock held | gl_spin spinlock held
-----------------------------------------------------------------
go_xmote_th | Yes | No
go_xmote_bh | Yes | No
go_inval | Yes | No
go_demote_ok | Sometimes | Yes
go_lock | Yes | No
go_unlock | Yes | No
go_dump | Sometimes | Yes
N.B. Operations must not drop either the bit lock or the spinlock
if its held on entry. go_dump and do_demote_ok must never block.
Note that go_dump will only be called if the glock's state
indicates that it is caching uptodate data.
Glock locking order within GFS2:
1. i_mutex (if required)
2. Rename glock (for rename only)
3. Inode glock(s)
(Parents before children, inodes at "same level" with same parent in
lock number order)
4. Rgrp glock(s) (for (de)allocation operations)
5. Transaction glock (via gfs2_trans_begin) for non-read operations
6. Page lock (always last, very important!)
There are two glocks per inode. One deals with access to the inode
itself (locking order as above), and the other, known as the iopen
glock is used in conjunction with the i_nlink field in the inode to
determine the lifetime of the inode in question. Locking of inodes
is on a per-inode basis. Locking of rgrps is on a per rgrp basis.

The default_smp_affinity mask applies to all non-active IRQs, which are the
IRQs which have not yet been allocated/activated, and hence which lack a
/proc/irq/[0-9]* directory.

This means that only the first CPU will handle the IRQ, but you can also echo 5
which means that only the first and fourth CPU can handle the IRQ.
prof_cpu_mask specifies which CPUs are to be profiled by the system wide
profiler. Default value is ffffffff (all cpus).

Description
-----------
WARNING: If you have an '810' or '815' motherboard, your standard I2C
temperature sensors are most likely on the 801's I2C bus. You want the
i2c-i801 driver for those, not this driver.
Now for the i2c-i810...
The GMCH chip contains two I2C interfaces.
The first interface is used for DDC (Data Display Channel) which is a
serial channel through the VGA monitor connector to a DDC-compliant
monitor. This interface is defined by the Video Electronics Standards
Association (VESA). The standards are available for purchase at
http://www.vesa.org .
The second interface is a general-purpose I2C bus. It may be connected to a
TV-out chip such as the BT869 or possibly to a digital flat-panel display.
Features
--------
Both busses use the i2c-algo-bit driver for 'bit banging'
and support for specific transactions is provided by i2c-algo-bit.
Issues
------
If you enable bus testing in i2c-algo-bit (insmod i2c-algo-bit bit_test=1),
the test may fail; if so, the i2c-i810 driver won't be inserted. However,
we think this has been fixed.

This is a summary of the most important conventions for use of fault
codes in the I2C/SMBus stack.
A "Fault" is not always an "Error"
----------------------------------
Not all fault reports imply errors; "page faults" should be a familiar
example. Software often retries idempotent operations after transient
faults. There may be fancier recovery schemes that are appropriate in
some cases, such as re-initializing (and maybe resetting). After such
recovery, triggered by a fault report, there is no error.
In a similar way, sometimes a "fault" code just reports one defined
result for an operation ... it doesn't indicate that anything is wrong
at all, just that the outcome wasn't on the "golden path".
In short, your I2C driver code may need to know these codes in order
to respond correctly. Other code may need to rely on YOUR code reporting
the right fault code, so that it can (in turn) behave correctly.
I2C and SMBus fault codes
-------------------------
These are returned as negative numbers from most calls, with zero or
some positive number indicating a non-fault return. The specific
numbers associated with these symbols differ between architectures,
though most Linux systems use <asm-generic/errno*.h> numbering.
Note that the descriptions here are not exhaustive. There are other
codes that may be returned, and other cases where these codes should
be returned. However, drivers should not return other codes for these
cases (unless the hardware doesn't provide unique fault reports).
Also, codes returned by adapter probe methods follow rules which are
specific to their host bus (such as PCI, or the platform bus).
EAGAIN
Returned by I2C adapters when they lose arbitration in master
transmit mode: some other master was transmitting different
data at the same time.
Also returned when trying to invoke an I2C operation in an
atomic context, when some task is already using that I2C bus
to execute some other operation.
EBADMSG
Returned by SMBus logic when an invalid Packet Error Code byte
is received. This code is a CRC covering all bytes in the
transaction, and is sent before the terminating STOP. This
fault is only reported on read transactions; the SMBus slave
may have a way to report PEC mismatches on writes from the
host. Note that even if PECs are in use, you should not rely
on these as the only way to detect incorrect data transfers.
EBUSY
Returned by SMBus adapters when the bus was busy for longer
than allowed. This usually indicates some device (maybe the
SMBus adapter) needs some fault recovery (such as resetting),
or that the reset was attempted but failed.
EINVAL
This rather vague error means an invalid parameter has been
detected before any I/O operation was started. Use a more
specific fault code when you can.
One example would be a driver trying an SMBus Block Write
with block size outside the range of 1-32 bytes.
EIO
This rather vague error means something went wrong when
performing an I/O operation. Use a more specific fault
code when you can.
ENODEV
Returned by driver probe() methods. This is a bit more
specific than ENXIO, implying the problem isn't with the
address, but with the device found there. Driver probes
may verify the device returns *correct* responses, and
return this as appropriate. (The driver core will warn
about probe faults other than ENXIO and ENODEV.)
ENOMEM
Returned by any component that can't allocate memory when
it needs to do so.
ENXIO
Returned by I2C adapters to indicate that the address phase
of a transfer didn't get an ACK. While it might just mean
an I2C device was temporarily not responding, usually it
means there's nothing listening at that address.
Returned by driver probe() methods to indicate that they
found no device to bind to. (ENODEV may also be used.)
EOPNOTSUPP
Returned by an adapter when asked to perform an operation
that it doesn't, or can't, support.
For example, this would be returned when an adapter that
doesn't support SMBus block transfers is asked to execute
one. In that case, the driver making that request should
have verified that functionality was supported before it
made that block transfer request.
Similarly, if an I2C adapter can't execute all legal I2C
messages, it should return this when asked to perform a
transaction it can't. (These limitations can't be seen in
the adapter's functionality mask, since the assumption is
that if an adapter supports I2C it supports all of I2C.)
EPROTO
Returned when slave does not conform to the relevant I2C
or SMBus (or chip-specific) protocol specifications. One
case is when the length of an SMBus block data response
(from the SMBus slave) is outside the range 1-32 bytes.
ETIMEDOUT
This is returned by drivers when an operation took too much
time, and was aborted before it completed.
SMBus adapters may return it when an operation took more
time than allowed by the SMBus specification; for example,
when a slave stretches clocks too far. I2C has no such
timeouts, but it's normal for I2C adapters to impose some
arbitrary limits (much longer than SMBus!) too.

Device Detection (Standard driver model)
----------------------------------------
Sometimes you do not know in advance which I2C devices are connected to
a given I2C bus. This is for example the case of hardware monitoring
devices on a PC's SMBus. In that case, you may want to let your driver
detect supported devices automatically. This is how the legacy model
was working, and is now available as an extension to the standard
driver model (so that we can finally get rid of the legacy model.)
You simply have to define a detect callback which will attempt to
identify supported devices (returning 0 for supported ones and -ENODEV
for unsupported ones), a list of addresses to probe, and a device type
(or class) so that only I2C buses which may have that type of device
connected (and not otherwise enumerated) will be probed. The i2c
core will then call you back as needed and will instantiate a device
for you for every successful detection.
Note that this mechanism is purely optional and not suitable for all
devices. You need some reliable way to identify the supported devices
(typically using device-specific, dedicated identification registers),
otherwise misdetections are likely to occur and things can get wrong
quickly.
