For cards that don't generate interrupts but need to be
polled, there is the possibility to set up a timer that
triggers the interrupt handler at configurable time intervals.
See <filename>drivers/uio/uio_dummy.c</filename> for an
example of this technique.

<title>Using uio_dummy</title>
<para>
Well, there is no real use for uio_dummy. Its only purpose is
to test most parts of the UIO system (everything except
hardware interrupts), and to serve as an example for the
kernel module that you will have to write yourself.

<title>What uio_dummy does</title>
<para>
The kernel module <filename>uio_dummy.ko</filename> creates a
device that uses a timer to generate periodic interrupts. The
interrupt handler does nothing but increment a counter. The
driver adds two custom attributes, <varname>count</varname>
and <varname>freq</varname>, that appear under
<filename>/sys/devices/platform/uio_dummy/</filename>.
</para>
<para>
The attribute <varname>count</varname> can be read and
written. The associated file
<filename>/sys/devices/platform/uio_dummy/count</filename>
appears as a normal text file and contains the total number of
timer interrupts. If you look at it (e.g. using
<function>cat</function>), you'll notice it is slowly counting
up.
</para>
<para>
The attribute <varname>freq</varname> can be read and written.
The content of
<filename>/sys/devices/platform/uio_dummy/freq</filename>
represents the number of system timer ticks between two timer
interrupts. The default value of <varname>freq</varname> is
the value of the kernel variable <varname>HZ</varname>, which
gives you an interval of one second. Lower values will
increase the frequency. Try the following:
</para>
<programlisting format="linespecific">
cd /sys/devices/platform/uio_dummy/
echo 100 > freq
</programlisting>
<para>
Use <function>cat count</function> to see how the interrupt
frequency changes.

initialization. If you don't have a hardware generated interrupt but
want to trigger the interrupt handler in some other way, set
<varname>irq</varname> to <varname>UIO_IRQ_CUSTOM</varname>. The
uio_dummy module does this as it triggers the event mechanism in a timer
routine. If you had no interrupt at all, you could set

Namespaces compatibility list
This document contains the information about the problems user
may have when creating tasks living in different namespaces.
Here's the summary. This matrix shows the known problems, that
occur when tasks share some namespace (the columns) while living
in different other namespaces (the rows):
UTS IPC VFS PID User Net
UTS X
IPC X 1
VFS X
PID 1 1 X
User 2 2 X
Net X
1. Both the IPC and the PID namespaces provide IDs to address
object inside the kernel. E.g. semaphore with IPCID or
process group with pid.
In both cases, tasks shouldn't try exposing this ID to some
other task living in a different namespace via a shared filesystem
or IPC shmem/message. The fact is that this ID is only valid
within the namespace it was obtained in and may refer to some
other object in another namespace.
2. Intentionally, two equal user IDs in different user namespaces
should not be equal from the VFS point of view. In other
words, user 10 in one user namespace shouldn't have the same
access permissions to files, belonging to user 10 in another
namespace.
The same is true for the IPC namespaces being shared - two users
from different user namespaces should not access the same IPC objects
even having equal UIDs.
But currently this is not so.

This feature allows software control of the LCD brightness on ThinkPad

battery" functionality will be enabled by the BIOS when this interface is

The backlight control has eight levels, ranging from 0 to 7. Some of the

On IBM (and some of the earlier Lenovo) ThinkPads, the backlight control
has eight brightness levels, ranging from 0 to 7. Some of the levels
may not be distinct. Later Lenovo models that implement the ACPI
display backlight brightness control methods have 16 levels, ranging
from 0 to 15.
There are two interfaces to the firmware for brightness control, EC and CMOS.
To select which one should be used, use the brightness_mode module parameter:
brightness_mode=1 selects EC mode, brightness_mode=2 selects CMOS mode,
brightness_mode=3 selects both EC and CMOS. The driver tries to autodetect
which interface to use.
There are two interfaces to the firmware for direct brightness control,
EC and CMOS. To select which one should be used, use the
brightness_mode module parameter: brightness_mode=1 selects EC mode,
brightness_mode=2 selects CMOS mode, brightness_mode=3 selects both EC
and CMOS. The driver tries to autodetect which interface to use.
When display backlight brightness controls are available through the
standard ACPI interface, it is best to use it instead of this direct
ThinkPad-specific interface. The driver will disable its native
backlight brightness control interface if it detects that the standard
ACPI interface is available in the ThinkPad.
The brightness_enable module parameter can be used to control whether
the LCD brightness control feature will be enabled when available.
brightness_enable=0 forces it to be disabled. brightness_enable=1
forces it to be enabled when available, even if the standard ACPI
interface is also available.

General note on [U]EFI x86_64 support
-------------------------------------
The nomenclature EFI and UEFI are used interchangeably in this document.
Although the tools below are _not_ needed for building the kernel,
the needed bootloader support and associated tools for x86_64 platforms
with EFI firmware and specifications are listed below.
1. UEFI specification: http://www.uefi.org
2. Booting Linux kernel on UEFI x86_64 platform requires bootloader
support. Elilo with x86_64 support can be used.
3. x86_64 platform with EFI/UEFI firmware.
Mechanics:
---------
- Build the kernel with the following configuration.
CONFIG_FB_EFI=y
CONFIG_FRAMEBUFFER_CONSOLE=y
- Create a VFAT partition on the disk
- Copy the following to the VFAT partition:
elilo bootloader with x86_64 support, elilo configuration file,
kernel image built in first step and corresponding
initrd. Instructions on building elilo and its dependencies
can be found in the elilo sourceforge project.
- Boot to EFI shell and invoke elilo choosing the kernel image built
in first step.

When enabled, the hardware error interrupt is never disabled, and

from.

help
Say Y here if you are getting weird unexplained errors. This will
ensure that icache is what SDRAM says it should be by doing a
byte wise comparison between SDRAM and instruction cache. This
also relocates the irq_panic() function to L1 memory, (which is
un-cached).

help
Say Y here to catch reads/writes to anywhere in the memory range
from 0x0000 - 0x0FFF (the first 4k) of memory. This is useful in
catching common programming errors such as NULL pointer dereferences.
Misbehaving applications will be killed (generate a SEGV) while the
kernel will trigger a panic.
Enabling this option will take up an extra entry in CPLB table.
Otherwise, there is no extra overhead.
config DEBUG_BFIN_HWTRACE_ON

help
All Blackfins include a Trace Unit which stores a history of the last
16 changes in program flow taken by the program sequencer. The history
allows the user to recreate the program sequencer’s recent path. This
can be handy when an application dies - we print out the execution
path of how it got to the offending instruction.
By turning this off, you may save a tiny amount of power.

The trace buffer can be configured to omit recording of changes in
program flow that match either the last entry or one of the last
two entries. Omitting one of these entries from the record prevents
the trace buffer from overflowing because of any sort of loop (for, do
while, etc) in the program.
Because zero-overhead Hardware loops are not recorded in the trace buffer,
this feature can be used to prevent trace overflow from loops that
are nested four deep.

This option enables special console drivers which allow the kernel

This is useful for kernel debugging when your machine crashes very
early before the console code is initialized. After enabling this
feature, you must add "earlyprintk=serial,uart0,57600" to the
