iii. Plugging the queue to batch requests in anticipation of opportunities for
|
||||
merge/sort optimizations
|
||||
|
||||
This is just the same as in 2.4 so far, though per-device unplugging
|
||||
support is anticipated for 2.5. Also with a priority-based i/o scheduler,
|
||||
such decisions could be based on request priorities.
|
||||
|
||||
Plugging is an approach that the current i/o scheduling algorithm resorts to so
|
||||
that it collects up enough requests in the queue to be able to take
|
||||
advantage of the sorting/merging logic in the elevator. If the
|
||||
queue is empty when a request comes in, then it plugs the request queue
|
||||
(sort of like plugging the bottom of a vessel to get fluid to build up)
|
||||
(sort of like plugging the bath tub of a vessel to get fluid to build up)
|
||||
till it fills up with a few more requests, before starting to service
|
||||
the requests. This provides an opportunity to merge/sort the requests before
|
||||
passing them down to the device. There are various conditions when the queue is
|
||||
unplugged (to open up the flow again), either through a scheduled task or
|
||||
could be on demand. For example wait_on_buffer sets the unplugging going
|
||||
(by running tq_disk) so the read gets satisfied soon. So in the read case,
|
||||
the queue gets explicitly unplugged as part of waiting for completion,
|
||||
in fact all queues get unplugged as a side-effect.
|
||||
through sync_buffer() running blk_run_address_space(mapping). Or the caller
|
||||
can do it explicity through blk_unplug(bdev). So in the read case,
|
||||
the queue gets explicitly unplugged as part of waiting for completion on that
|
||||
buffer. For page driven IO, the address space ->sync_page() takes care of
|
||||
doing the blk_run_address_space().

|

|
||||
Datagram vs Connected modes
|
||||
|
||||
The IPoIB driver supports two modes of operation: datagram and
|
||||
connected. The mode is set and read through an interface's
|
||||
/sys/class/net/<intf name>/mode file.
|
||||
|
||||
In datagram mode, the IB UD (Unreliable Datagram) transport is used
|
||||
and so the interface MTU has is equal to the IB L2 MTU minus the
|
||||
IPoIB encapsulation header (4 bytes). For example, in a typical IB
|
||||
fabric with a 2K MTU, the IPoIB MTU will be 2048 - 4 = 2044 bytes.
|
||||
|
||||
In connected mode, the IB RC (Reliable Connected) transport is used.
|
||||
Connected mode is to takes advantage of the connected nature of the
|
||||
IB transport and allows an MTU up to the maximal IP packet size of
|
||||
64K, which reduces the number of IP packets needed for handling
|
||||
large UDP datagrams, TCP segments, etc and increases the performance
|
||||
for large messages.
|
||||
|
||||
In connected mode, the interface's UD QP is still used for multicast
|
||||
and communication with peers that don't support connected mode. In
|
||||
this case, RX emulation of ICMP PMTU packets is used to cause the
|
||||
networking stack to use the smaller UD MTU for these neighbours.
|
||||
|
||||
Stateless offloads
|
||||
|
||||
If the IB HW supports IPoIB stateless offloads, IPoIB advertises
|
||||
TCP/IP checksum and/or Large Send (LSO) offloading capability to the
|
||||
network stack.
|
||||
|
||||
Large Receive (LRO) offloading is also implemented and may be turned
|
||||
on/off using ethtool calls. Currently LRO is supported only for
|
||||
checksum offload capable devices.
|
||||
|
||||
Stateless offloads are supported only in datagram mode.
|
||||
|
||||
Interrupt moderation
|
||||
|
||||
If the underlying IB device supports CQ event moderation, one can
|
||||
use ethtool to set interrupt mitigation parameters and thus reduce
|
||||
the overhead incurred by handling interrupts. The main code path of
|
||||
IPoIB doesn't use events for TX completion signaling so only RX
|
||||
moderation is supported.

rotary-encoder - a generic driver for GPIO connected devices

Daniel Mack <daniel@caiaq.de>, Feb 2009

|
||||
0. Function
|
||||
-----------
|
||||
|
||||
Rotary encoders are devices which are connected to the CPU or other
|
||||
peripherals with two wires. The outputs are phase-shifted by 90 degrees
|
||||
and by triggering on falling and rising edges, the turn direction can
|
||||
be determined.
|
||||
|
||||
The phase diagram of these two outputs look like this:

||||

http://en.wikipedia.org/wiki/Rotary_encoder
|
||||
|
||||
|
||||
1. Events / state machine
|
||||
-------------------------
|
||||
|
||||
a) Rising edge on channel A, channel B in low state
|
||||
This state is used to recognize a clockwise turn
|
||||
|
||||
b) Rising edge on channel B, channel A in high state
|
||||
When entering this state, the encoder is put into 'armed' state,
|
||||
meaning that there it has seen half the way of a one-step transition.
|
||||
|
||||
c) Falling edge on channel A, channel B in high state
|
||||
This state is used to recognize a counter-clockwise turn
|
||||
|
||||
d) Falling edge on channel B, channel A in low state
|
||||
Parking position. If the encoder enters this state, a full transition
|
||||
should have happend, unless it flipped back on half the way. The
|
||||
'armed' state tells us about that.
|
||||
|
||||
2. Platform requirements
|
||||
------------------------
|
||||
|
||||
As there is no hardware dependent call in this driver, the platform it is
|
||||
used with must support gpiolib. Another requirement is that IRQs must be
|
||||
able to fire on both edges.
|
||||
|
||||
|
||||
3. Board integration
|
||||
--------------------
|
||||
|
||||
To use this driver in your system, register a platform_device with the
|
||||
name 'rotary-encoder' and associate the IRQs and some specific platform
|
||||
data with it.
|
||||
|
||||
struct rotary_encoder_platform_data is declared in
|
||||
include/linux/rotary-encoder.h and needs to be filled with the number of
|
||||
steps the encoder has and can carry information about externally inverted
|
||||
signals (because of used invertig buffer or other reasons).
|
||||
|
||||
Because GPIO to IRQ mapping is platform specific, this information must
|
||||
be given in seperately to the driver. See the example below.

The kbuild infrastructure for *lds file are used in several
|
||||
architecture-specific files.
|
||||
|
||||
=== 7 Kbuild syntax for exported headers
|
||||
|
||||
=== 7 Kbuild Variables
|
||||
The kernel include a set of headers that is exported to userspace.
|
||||
Many headers can be exported as-is but other headers requires a
|
||||
minimal pre-processing before they are ready for user-space.
|
||||
The pre-processing does:
|
||||
- drop kernel specific annotations
|
||||
- drop include of compiler.h
|
||||
- drop all sections that is kernel internat (guarded by ifdef __KERNEL__)
|
||||
|
||||
Each relevant directory contain a file name "Kbuild" which specify the
|
||||
headers to be exported.
|
||||
See subsequent chapter for the syntax of the Kbuild file.
|
||||
|
||||
--- 7.1 header-y
|
||||
|
||||
header-y specify header files to be exported.
|
||||
|
||||
Example:
|
||||
#include/linux/Kbuild
|
||||
header-y += usb/
|
||||
header-y += aio_abi.h
|
||||
|
||||
The convention is to list one file per line and
|
||||
preferably in alphabetic order.
|
||||
|
||||
header-y also specify which subdirectories to visit.
|
||||
A subdirectory is identified by a trailing '/' which
|
||||
can be seen in the example above for the usb subdirectory.
|
||||
|
||||
Subdirectories are visited before their parent directories.
|
||||
|
||||
--- 7.2 objhdr-y
|
||||
|
||||
objhdr-y specifies generated files to be exported.
|
||||
Generated files are special as they need to be looked
|
||||
up in another directory when doing 'make O=...' builds.
|
||||
|
||||
Example:
|
||||
#include/linux/Kbuild
|
||||
objhdr-y += version.h
|
||||
|
||||
--- 7.3 destination-y
|
||||
|
||||
When an architecture have a set of exported headers that needs to be
|
||||
exported to a different directory destination-y is used.
|
||||
destination-y specify the destination directory for all exported
|
||||
headers in the file where it is present.
|
||||
|
||||
Example:
|
||||
#arch/xtensa/platforms/s6105/include/platform/Kbuild
|
||||
destination-y := include/linux
|
||||
|
||||
In the example above all exported headers in the Kbuild file
|
||||
will be located in the directory "include/linux" when exported.
|
||||
|
||||
|
||||
--- 7.4 unifdef-y (deprecated)
|
||||
|
||||
unifdef-y is deprecated. A direct replacement is header-y.

--- What is TOMOYO? ---
|
||||
|
||||
TOMOYO is a name-based MAC extension (LSM module) for the Linux kernel.
|
||||
|
||||
LiveCD-based tutorials are available at
|
||||
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/ubuntu8.04-live/
|
||||
http://tomoyo.sourceforge.jp/en/1.6.x/1st-step/centos5-live/ .
|
||||
Though these tutorials use non-LSM version of TOMOYO, they are useful for you
|
||||
to know what TOMOYO is.
|
||||
|
||||
--- How to enable TOMOYO? ---
|
||||
|
||||
Build the kernel with CONFIG_SECURITY_TOMOYO=y and pass "security=tomoyo" on
|
||||
kernel's command line.
|
||||
|
||||
Please see http://tomoyo.sourceforge.jp/en/2.2.x/ for details.
|
||||
|
||||
--- Where is documentation? ---
|
||||
|
||||
User <-> Kernel interface documentation is available at

||||

--- What is future plan? ---
|
||||
|
||||
We believe that inode based security and name based security are complementary
|
||||
and both should be used together. But unfortunately, so far, we cannot enable
|
||||
multiple LSM modules at the same time. We feel sorry that you have to give up
|
||||
SELinux/SMACK/AppArmor etc. when you want to use TOMOYO.
|
||||
|
||||
We hope that LSM becomes stackable in future. Meanwhile, you can use non-LSM
|
||||
version of TOMOYO, available at http://tomoyo.sourceforge.jp/en/1.6.x/ .
|
||||
LSM version of TOMOYO is a subset of non-LSM version of TOMOYO. We are planning
|
||||
to port non-LSM version's functionalities to LSM versions.

|
||||
|
||||
Basically, the new setup is:
|
||||
|
||||
- we have "real address spaces" and "anonymous address spaces". The
|
||||
difference is that an anonymous address space doesn't care about the
|
||||
user-level page tables at all, so when we do a context switch into an
|
||||
anonymous address space we just leave the previous address space
|
||||
active.
|
||||
|
||||
The obvious use for a "anonymous address space" is any thread that
|
||||
doesn't need any user mappings - all kernel threads basically fall into
|
||||
this category, but even "real" threads can temporarily say that for
|
||||
some amount of time they are not going to be interested in user space,
|
||||
and that the scheduler might as well try to avoid wasting time on
|
||||
switching the VM state around. Currently only the old-style bdflush
|
||||
sync does that.
|
||||
|
||||
- "tsk->mm" points to the "real address space". For an anonymous process,
|
||||
tsk->mm will be NULL, for the logical reason that an anonymous process
|
||||
really doesn't _have_ a real address space at all.
|
||||
|
||||
- however, we obviously need to keep track of which address space we
|
||||
"stole" for such an anonymous user. For that, we have "tsk->active_mm",
|
||||
which shows what the currently active address space is.
|
||||
|
||||
The rule is that for a process with a real address space (ie tsk->mm is
|
||||
non-NULL) the active_mm obviously always has to be the same as the real
|
||||
one.
|
||||
|
||||
For a anonymous process, tsk->mm == NULL, and tsk->active_mm is the
|
||||
"borrowed" mm while the anonymous process is running. When the
|
||||
anonymous process gets scheduled away, the borrowed address space is
|
||||
returned and cleared.
|
||||
|
||||
To support all that, the "struct mm_struct" now has two counters: a
|
||||
"mm_users" counter that is how many "real address space users" there are,
|
||||
and a "mm_count" counter that is the number of "lazy" users (ie anonymous
|
||||
users) plus one if there are any real users.
|
||||
|
||||
Usually there is at least one real user, but it could be that the real
|
||||
user exited on another CPU while a lazy user was still active, so you do
|
||||
actually get cases where you have a address space that is _only_ used by
|
||||
lazy users. That is often a short-lived state, because once that thread
|
||||
gets scheduled away in favour of a real thread, the "zombie" mm gets
|
||||
released because "mm_users" becomes zero.
|
||||
|
||||
Also, a new rule is that _nobody_ ever has "init_mm" as a real MM any
|
||||
more. "init_mm" should be considered just a "lazy context when no other
|
||||
context is available", and in fact it is mainly used just at bootup when
|
||||
no real VM has yet been created. So code that used to check
|
||||
|
||||
if (current->mm == &init_mm)
|
||||
|
||||
should generally just do
|
||||
|
||||
if (!current->mm)
|
||||
|
||||
instead (which makes more sense anyway - the test is basically one of "do
|
||||
we have a user context", and is generally done by the page fault handler
|
||||
and things like that).
|
||||
|
||||
Anyway, I put a pre-patch-2.3.13-1 on ftp.kernel.org just a moment ago,
|
||||
because it slightly changes the interfaces to accomodate the alpha (who
|
||||
would have thought it, but the alpha actually ends up having one of the
|
||||
ugliest context switch codes - unlike the other architectures where the MM
|
||||
and register state is separate, the alpha PALcode joins the two, and you
|
||||
need to switch both together).
