What: /sys/devices/platform/at91_can/net/<iface>/mb0_id

KernelVersion: 2.6.38

Description:
|
||||||
|
Value representing the can_id of mailbox 0.
|
||||||
|
|
||||||
|
Default: 0x7ff (standard frame)
|
||||||
|
|
||||||
|
Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
|
||||||
|
"AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
|
||||||
|
contents of mailbox 0 may be send under certain
|
||||||
|
conditions (even if disabled or in rx mode).
|
||||||
|
|
||||||
|
The workaround in the errata suggests not to use the
|
||||||
|
mailbox and load it with an unused identifier.
|
||||||
|
|
||||||
|
In order to use an extended can_id add the
|
||||||
|
CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
|
||||||
|
|
||||||
|
- standard id 0x7ff:
|
||||||
|
echo 0x7ff > /sys/class/net/can0/mb0_id
|
||||||
|
|
||||||
|
- extended id 0x1fffffff:
|
||||||
|
echo 0x9fffffff > /sys/class/net/can0/mb0_id

32-bit embedded kernels:
|
|

|
|
||||||
Currently, board support is essentially an exclusive config option.
|
|
||||||
The kernel is configured for a single platform. Part of the reason
|
|
||||||
for this is to keep kernels on embedded systems small and efficient;
|
|
||||||
part of this is due to the fact the code is already that way. In the
|
|

future, a kernel may support multiple platforms, but only if the

|
with classic Powerpc architectures.
|
||||||
|
|
||||||
32-bit embedded platforms that are moved into arch/powerpc using a
|
|
||||||
flattened device tree should adopt the merged tree practice of
|
|
||||||
setting ppc_md up dynamically, even though the kernel is currently
|
|
||||||
built with support for only a single platform at a time. This allows
|
|
||||||
unification of the setup code, and will make it easier to go to a
|
|
||||||
multiple-platform-support model in the future.
|
|
||||||
|
|
||||||
NOTE: I believe the above will be true once Ben's done with the merge
|
|
||||||
of the boot sequences.... someone speak up if this is wrong!
|
|
||||||
|
|
||||||
To add a 32-bit embedded platform support, follow the instructions
|
|
||||||
for 64-bit platforms above, with the exception that the Kconfig
|
|
||||||
option should be set up such that the kernel builds exclusively for
|
|
||||||
the platform selected. The processor type for the platform should
|
|
||||||
enable another config option to select the specific board
|
|
||||||
supported.
|
|
||||||
|
|
||||||
NOTE: If Ben doesn't merge the setup files, may need to change this to
|
|
||||||
point to setup_32.c
|
|
||||||
|
|
||||||
|
|
||||||
I will describe later the boot process and various callbacks that
|
|
||||||
your platform should implement.

What: noswapaccount kernel command line parameter

When: 2.6.40
|

|
Why: The original implementation of memsw feature enabled by
|
||||||
|
CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
|
||||||
|
kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
|
||||||
|
turned out to be not ideal because we cannot have the feature compiled
|
||||||
|
in and disabled by default and let only interested to enable it
|
||||||
|
(e.g. general distribution kernels might need it). Therefore we have
|
||||||
|
added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
|
||||||
|
the both possibilities. If we remove noswapaccount we will have
|
||||||
|
less command line parameters with the same functionality and we
|
||||||
|
can also cleanup the parameter handling a bit ().

3.5 Configuration with Interfaces Support
|
||||||
|
-----------------------------------------
|
||||||
|
|
||||||
|
This section applies to distros which use /etc/network/interfaces file
|
||||||
|
to describe network interface configuration, most notably Debian and it's
|
||||||
|
derivatives.
|
||||||
|
|
||||||
|
The ifup and ifdown commands on Debian don't support bonding out of
|
||||||
|
the box. The ifenslave-2.6 package should be installed to provide bonding
|
||||||
|
support. Once installed, this package will provide bond-* options to be used
|
||||||
|
into /etc/network/interfaces.
|
||||||
|
|
||||||
|
Note that ifenslave-2.6 package will load the bonding module and use
|
||||||
|
the ifenslave command when appropriate.
|
||||||
|
|
||||||
|
Example Configurations
|
||||||
|
----------------------
|
||||||
|
|
||||||
|
In /etc/network/interfaces, the following stanza will configure bond0, in
|
||||||
|
active-backup mode, with eth0 and eth1 as slaves.
|
||||||
|
|
||||||
|
auto bond0
|
||||||
|
iface bond0 inet dhcp
|
||||||
|
bond-slaves eth0 eth1
|
||||||
|
bond-mode active-backup
|
||||||
|
bond-miimon 100
|
||||||
|
bond-primary eth0 eth1
|
||||||
|
|
||||||
|
If the above configuration doesn't work, you might have a system using
|
||||||
|
upstart for system startup. This is most notably true for recent
|
||||||
|
Ubuntu versions. The following stanza in /etc/network/interfaces will
|
||||||
|
produce the same result on those systems.
|
||||||
|
|
||||||
|
auto bond0
|
||||||
|
iface bond0 inet dhcp
|
||||||
|
bond-slaves none
|
||||||
|
bond-mode active-backup
|
||||||
|
bond-miimon 100

||||||
|
|
||||||
|

||||||
