4) Multiple cards
--------------------------
If you happen to be running multiple cards, it would be advisable to load
the bttv module with the card id. This would help to solve any module loading
problems that you might face.
For example, if you have a Twinhan and Clones card along with a FusionHDTV5 Lite
$ modprobe bttv card=0x71 card=0x87
Here the order of the card id is important and should be the same as that of the
physical order of the cards. Here card=0x71 represents the Twinhan and clones
and card=0x87 represents Fusion HDTV5 Lite. These arguments can also be
specified in decimal, rather than hex:
$ modprobe bttv card=113 card=135
Some examples of card-id's
Pinnacle Sat 0x5e (94)
Nebula Digi TV 0x68 (104)
PC HDTV 0x70 (112)
Twinhan 0x71 (113)
FusionHDTV DVB-T Lite 0x80 (128)
FusionHDTV5 Lite 0x87 (135)

The Framebuffer Console
=======================
The framebuffer console (fbcon), as its name implies, is a text
console running on top of the framebuffer device. It has the functionality of
any standard text console driver, such as the VGA console, with the added
features that can be attributed to the graphical nature of the framebuffer.
In the x86 architecture, the framebuffer console is optional, and
some even treat it as a toy. For other architectures, it is the only available
display device, text or graphical.
What are the features of fbcon? The framebuffer console supports
high resolutions, varying font types, display rotation, primitive multihead,
etc. Theoretically, multi-colored fonts, blending, aliasing, and any feature
made available by the underlying graphics card are also possible.
A. Configuration
The framebuffer console can be enabled by using your favorite kernel
configuration tool. It is under Device Drivers->Graphics Support->Support for
framebuffer devices->Framebuffer Console Support. Select 'y' to compile
support statically, or 'm' for module support. The module will be fbcon.
In order for fbcon to activate, at least one framebuffer driver is
required, so choose from any of the numerous drivers available. For x86
systems, they almost universally have VGA cards, so vga16fb and vesafb will
always be available. However, using a chipset-specific driver will give you
more speed and features, such as the ability to change the video mode
dynamically.
To display the penguin logo, choose any logo available in Logo
Configuration->Boot up logo.
Also, you will need to select at least one compiled-in fonts, but if
you don't do anything, the kernel configuration tool will select one for you,
usually an 8x16 font.
GOTCHA: A common bug report is enabling the framebuffer without enabling the
framebuffer console. Depending on the driver, you may get a blanked or
garbled display, but the system still boots to completion. If you are
fortunate to have a driver that does not alter the graphics chip, then you
will still get a VGA console.
B. Loading
Possible scenarios:
1. Driver and fbcon are compiled statically
Usually, fbcon will automatically take over your console. The notable
exception is vesafb. It needs to be explicitly activated with the
vga= boot option parameter.
2. Driver is compiled statically, fbcon is compiled as a module
Depending on the driver, you either get a standard console, or a
garbled display, as mentioned above. To get a framebuffer console,
do a 'modprobe fbcon'.
3. Driver is compiled as a module, fbcon is compiled statically
You get your standard console. Once the driver is loaded with
'modprobe xxxfb', fbcon automatically takes over the console with
the possible exception of using the fbcon=map:n option. See below.
4. Driver and fbcon are compiled as a module.
You can load them in any order. Once both are loaded, fbcon will take
over the console.
C. Boot options
The framebuffer console has several, largely unknown, boot options
that can change its behavior.
1. fbcon=font:<name>
Select the initial font to use. The value 'name' can be any of the
compiled-in fonts: VGA8x16, 7x14, 10x18, VGA8x8, MINI4x6, RomanLarge,
SUN8x16, SUN12x22, ProFont6x11, Acorn8x8, PEARL8x8.
Note, not all drivers can handle font with widths not divisible by 8,
such as vga16fb.
2. fbcon=scrollback:<value>[k]
The scrollback buffer is memory that is used to preserve display
contents that has already scrolled past your view. This is accessed
by using the Shift-PageUp key combination. The value 'value' is any
integer. It defaults to 32KB. The 'k' suffix is optional, and will
multiply the 'value' by 1024.
3. fbcon=map:<0123>
This is an interesting option. It tells which driver gets mapped to
which console. The value '0123' is a sequence that gets repeated until
the total length is 64 which is the number of consoles available. In
the above example, it is expanded to 012301230123... and the mapping
will be:
tty | 1 2 3 4 5 6 7 8 9 ...
fb | 0 1 2 3 0 1 2 3 0 ...
('cat /proc/fb' should tell you what the fb numbers are)
One side effect that may be useful is using a map value that exceeds
the number of loaded fb drivers. For example, if only one driver is
available, fb0, adding fbcon=map:1 tells fbcon not to take over the
console.
Later on, when you want to map the console the to the framebuffer
device, you can use the con2fbmap utility.
4. fbcon=vc:<n1>-<n2>
This option tells fbcon to take over only a range of consoles as
specified by the values 'n1' and 'n2'. The rest of the consoles
outside the given range will still be controlled by the standard
console driver.
NOTE: For x86 machines, the standard console is the VGA console which
is typically located on the same video card. Thus, the consoles that
are controlled by the VGA console will be garbled.
4. fbcon=rotate:<n>
This option changes the orientation angle of the console display. The
value 'n' accepts the following:
0 - normal orientation (0 degree)
1 - clockwise orientation (90 degrees)
2 - upside down orientation (180 degrees)
3 - counterclockwise orientation (270 degrees)
The angle can be changed anytime afterwards by 'echoing' the same
numbers to any one of the 2 attributes found in
/sys/class/graphics/fb{x}
con_rotate - rotate the display of the active console
con_rotate_all - rotate the display of all consoles
Console rotation will only become available if Console Rotation
Support is compiled in your kernel.
NOTE: This is purely console rotation. Any other applications that
use the framebuffer will remain at their 'normal'orientation.
Actually, the underlying fb driver is totally ignorant of console
rotation.

MD devices in sysfs
-------------------
md devices appear in sysfs (/sys) as regular block devices,
e.g.
/sys/block/md0
Each 'md' device will contain a subdirectory called 'md' which
contains further md-specific information about the device.
All md devices contain:
level
a text file indicating the 'raid level'. This may be a standard
numerical level prefixed by "RAID-" - e.g. "RAID-5", or some
other name such as "linear" or "multipath".
If no raid level has been set yet (array is still being
assembled), this file will be empty.
raid_disks
a text file with a simple number indicating the number of devices
in a fully functional array. If this is not yet known, the file
will be empty. If an array is being resized (not currently
possible) this will contain the larger of the old and new sizes.
As component devices are added to an md array, they appear in the 'md'
directory as new directories named
dev-XXX
where XXX is a name that the kernel knows for the device, e.g. hdb1.
Each directory contains:
block
a symlink to the block device in /sys/block, e.g.
/sys/block/md0/md/dev-hdb1/block -> ../../../../block/hdb/hdb1
super
A file containing an image of the superblock read from, or
written to, that device.
state
A file recording the current state of the device in the array
which can be a comma separated list of
faulty - device has been kicked from active use due to
a detected fault
in_sync - device is a fully in-sync member of the array
spare - device is working, but not a full member.
This includes spares that are in the process
of being recoverred to
This list make grow in future.
An active md device will also contain and entry for each active device
in the array. These are named
rdNN
where 'NN' is the possition in the array, starting from 0.
So for a 3 drive array there will be rd0, rd1, rd2.
These are symbolic links to the appropriate 'dev-XXX' entry.
Thus, for example,
cat /sys/block/md*/md/rd*/state
will show 'in_sync' on every line.
Active md devices for levels that support data redundancy (1,4,5,6)
also have
sync_action
a text file that can be used to monitor and control the rebuild
process. It contains one word which can be one of:
resync - redundancy is being recalculated after unclean
shutdown or creation
recover - a hot spare is being built to replace a
failed/missing device
idle - nothing is happening
check - A full check of redundancy was requested and is
happening. This reads all block and checks
them. A repair may also happen for some raid
levels.
repair - A full check and repair is happening. This is
similar to 'resync', but was requested by the
user, and the write-intent bitmap is NOT used to
optimise the process.
This file is writable, and each of the strings that could be
read are meaningful for writing.
'idle' will stop an active resync/recovery etc. There is no
guarantee that another resync/recovery may not be automatically
started again, though some event will be needed to trigger
this.
'resync' or 'recovery' can be used to restart the
corresponding operation if it was stopped with 'idle'.
'check' and 'repair' will start the appropriate process
providing the current state is 'idle'.
mismatch_count
When performing 'check' and 'repair', and possibly when
performing 'resync', md will count the number of errors that are
found. The count in 'mismatch_cnt' is the number of sectors
that were re-written, or (for 'check') would have been
re-written. As most raid levels work in units of pages rather
than sectors, this my be larger than the number of actual errors
by a factor of the number of sectors in a page.
Each active md device may also have attributes specific to the
personality module that manages it.
These are specific to the implementation of the module and could
change substantially if the implementation changes.
These currently include
stripe_cache_size (currently raid5 only)
number of entries in the stripe cache. This is writable, but
there are upper and lower limits (32768, 16). Default is 128.
strip_cache_active (currently raid5 only)
number of active entries in the stripe cache

-----------------------------------------------
Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
Intel wireless LAN adapters are engineered, manufactured, tested, and
quality checked to ensure that they meet all necessary local and
governmental regulatory agency requirements for the regions that they
are designated and/or marked to ship into. Since wireless LANs are
generally unlicensed devices that share spectrum with radars,
satellites, and other licensed and unlicensed devices, it is sometimes
necessary to dynamically detect, avoid, and limit usage to avoid
interference with these devices. In many instances Intel is required to
provide test data to prove regional and local compliance to regional and
governmental regulations before certification or approval to use the
product is granted. Intel's wireless LAN's EEPROM, firmware, and
software driver are designed to carefully control parameters that affect
radio operation and to ensure electromagnetic compliance (EMC). These
parameters include, without limitation, RF power, spectrum usage,
channel scanning, and human exposure.
For these reasons Intel cannot permit any manipulation by third parties
of the software provided in binary format with the wireless WLAN
adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
patches, utilities, or code with the Intel wireless LAN adapters that
have been manipulated by an unauthorized party (i.e., patches,
utilities, or code (including open source code modifications) which have
not been validated by Intel), (i) you will be solely responsible for
ensuring the regulatory compliance of the products, (ii) Intel will bear
no liability, under any theory of liability for any issues associated
with the modified products, including without limitation, claims under
the warranty and/or issues arising from regulatory non-compliance, and
(iii) Intel will not provide or be required to assist in providing
support to any third parties for such modified products.
Note: Many regulatory agencies consider Wireless LAN adapters to be
modules, and accordingly, condition system-level regulatory approval
upon receipt and review of test data documenting that the antennas and
system configuration do not cause the EMC and radio operation to be
non-compliant.
The drivers available for download from SourceForge are provided as a

-----------------------------------------------
Important Notice FOR ALL USERS OR DISTRIBUTORS!!!!
Intel wireless LAN adapters are engineered, manufactured, tested, and
quality checked to ensure that they meet all necessary local and
governmental regulatory agency requirements for the regions that they
are designated and/or marked to ship into. Since wireless LANs are
generally unlicensed devices that share spectrum with radars,
satellites, and other licensed and unlicensed devices, it is sometimes
necessary to dynamically detect, avoid, and limit usage to avoid
interference with these devices. In many instances Intel is required to
provide test data to prove regional and local compliance to regional and
governmental regulations before certification or approval to use the
product is granted. Intel's wireless LAN's EEPROM, firmware, and
software driver are designed to carefully control parameters that affect
radio operation and to ensure electromagnetic compliance (EMC). These
parameters include, without limitation, RF power, spectrum usage,
channel scanning, and human exposure.
For these reasons Intel cannot permit any manipulation by third parties
of the software provided in binary format with the wireless WLAN
adapters (e.g., the EEPROM and firmware). Furthermore, if you use any
patches, utilities, or code with the Intel wireless LAN adapters that
have been manipulated by an unauthorized party (i.e., patches,
utilities, or code (including open source code modifications) which have
not been validated by Intel), (i) you will be solely responsible for
ensuring the regulatory compliance of the products, (ii) Intel will bear
no liability, under any theory of liability for any issues associated
with the modified products, including without limitation, claims under
the warranty and/or issues arising from regulatory non-compliance, and
(iii) Intel will not provide or be required to assist in providing
support to any third parties for such modified products.
Note: Many regulatory agencies consider Wireless LAN adapters to be
modules, and accordingly, condition system-level regulatory approval
upon receipt and review of test data documenting that the antennas and
system configuration do not cause the EMC and radio operation to be
non-compliant.
The drivers available for download from SourceForge are provided as a
part of a development project. Conformance to local regulatory
requirements is the responsibility of the individual developer. As
such, if you are interested in deploying or shipping a driver as part of
solution intended to be used for purposes other than development, please

NOTE: The LED code has been reported to hang some systems when
running ifconfig and is therefore disabled by default.
2. Ad-Hoc Networking
-----------------------------------------------
When using a device in an Ad-Hoc network, it is useful to understand the
sequence and requirements for the driver to be able to create, join, or
merge networks.
The following attempts to provide enough information so that you can
have a consistent experience while using the driver as a member of an
Ad-Hoc network.
2.1. Joining an Ad-Hoc Network
-----------------------------------------------
The easiest way to get onto an Ad-Hoc network is to join one that
already exists.
2.2. Creating an Ad-Hoc Network
-----------------------------------------------
An Ad-Hoc networks is created using the syntax of the Wireless tool.
For Example:
iwconfig eth1 mode ad-hoc essid testing channel 2

CPU Scheduler implementation hints for architecture specific code
Nick Piggin, 2005
Context switch
==============
1. Runqueue locking
By default, the switch_to arch function is called with the runqueue
locked. This is usually not a problem unless switch_to may need to
take the runqueue lock. This is usually due to a wake up operation in
the context switch. See include/asm-ia64/system.h for an example.
To request the scheduler call switch_to with the runqueue unlocked,
you must `#define __ARCH_WANT_UNLOCKED_CTXSW` in a header file
(typically the one where switch_to is defined).
Unlocked context switches introduce only a very minor performance
penalty to the core scheduler implementation in the CONFIG_SMP case.
2. Interrupt status
By default, the switch_to arch function is called with interrupts
disabled. Interrupts may be enabled over the call if it is likely to
introduce a significant interrupt latency by adding the line
`#define __ARCH_WANT_INTERRUPTS_ON_CTXSW` in the same place as for
unlocked context switches. This define also implies
`__ARCH_WANT_UNLOCKED_CTXSW`. See include/asm-arm/system.h for an
example.
CPU idle
========
Your cpu_idle routines need to obey the following rules:
1. Preempt should now disabled over idle routines. Should only
be enabled to call schedule() then disabled again.
2. need_resched/TIF_NEED_RESCHED is only ever set, and will never
be cleared until the running task has called schedule(). Idle
threads need only ever query need_resched, and may never set or
clear it.
3. When cpu_idle finds (need_resched() == 'true'), it should call
schedule(). It should not call schedule() otherwise.
4. The only time interrupts need to be disabled when checking
need_resched is if we are about to sleep the processor until
the next interrupt (this doesn't provide any protection of
need_resched, it prevents losing an interrupt).
4a. Common problem with this type of sleep appears to be:
local_irq_disable();
if (!need_resched()) {
local_irq_enable();
*** resched interrupt arrives here ***
__asm__("sleep until next interrupt");
}
5. TIF_POLLING_NRFLAG can be set by idle routines that do not
need an interrupt to wake them up when need_resched goes high.
In other words, they must be periodically polling need_resched,
although it may be reasonable to do some background work or enter
a low CPU priority.
5a. If TIF_POLLING_NRFLAG is set, and we do decide to enter
an interrupt sleep, it needs to be cleared then a memory
barrier issued (followed by a test of need_resched with
interrupts disabled, as explained in 3).
arch/i386/kernel/process.c has examples of both polling and
sleeping idle functions.
Possible arch/ problems
=======================
Possible arch problems I found (and either tried to fix or didn't):
h8300 - Is such sleeping racy vs interrupts? (See #4a).
The H8/300 manual I found indicates yes, however disabling IRQs
over the sleep mean only NMIs can wake it up, so can't fix easily
without doing spin waiting.
ia64 - is safe_halt call racy vs interrupts? (does it sleep?) (See #4a)
sh64 - Is sleeping racy vs interrupts? (See #4a)
sparc - IRQs on at this point(?), change local_irq_save to _disable.
- TODO: needs secondary CPUs to disable preempt (See #1)
