1What: /sys/devices/platform/at91_can/net/<iface>/mb0_id
2Date: January 2011
3KernelVersion: 2.6.38
4Contact: Marc Kleine-Budde <kernel@pengutronix.de>
5Description:
6 Value representing the can_id of mailbox 0.
7
8 Default: 0x7ff (standard frame)
9
10 Due to a chip bug (errata 50.2.6.3 & 50.3.5.3 in
11 "AT91SAM9263 Preliminary 6249H-ATARM-27-Jul-09") the
12 contents of mailbox 0 may be send under certain
13 conditions (even if disabled or in rx mode).
14
15 The workaround in the errata suggests not to use the
16 mailbox and load it with an unused identifier.
17
18 In order to use an extended can_id add the
19 CAN_EFF_FLAG (0x80000000U) to the can_id. Example:
20
21 - standard id 0x7ff:
22 echo 0x7ff > /sys/class/net/can0/mb0_id
23
24 - extended id 0x1fffffff:
25 echo 0x9fffffff > /sys/class/net/can0/mb0_id

245
246 Currently, board support is essentially an exclusive config option.
247 The kernel is configured for a single platform. Part of the reason
248 for this is to keep kernels on embedded systems small and efficient;
249 part of this is due to the fact the code is already that way. In the
250 future, a kernel may support multiple platforms, but only if the
251 platforms feature the same core architecture. A single kernel build 224 platforms feature the same core architecture. A single kernel build

254 227
255 32-bit embedded platforms that are moved into arch/powerpc using a
256 flattened device tree should adopt the merged tree practice of
257 setting ppc_md up dynamically, even though the kernel is currently
258 built with support for only a single platform at a time. This allows
259 unification of the setup code, and will make it easier to go to a
260 multiple-platform-support model in the future.
261
262NOTE: I believe the above will be true once Ben's done with the merge
263of the boot sequences.... someone speak up if this is wrong!
264
265 To add a 32-bit embedded platform support, follow the instructions
266 for 64-bit platforms above, with the exception that the Kconfig
267 option should be set up such that the kernel builds exclusively for
268 the platform selected. The processor type for the platform should
269 enable another config option to select the specific board
270 supported.
271
272NOTE: If Ben doesn't merge the setup files, may need to change this to
273point to setup_32.c

275
276 I will describe later the boot process and various callbacks that
277 your platform should implement.

607What: noswapaccount kernel command line parameter
608When: 2.6.40
609Why: The original implementation of memsw feature enabled by
610 CONFIG_CGROUP_MEM_RES_CTLR_SWAP could be disabled by the noswapaccount
611 kernel parameter (introduced in 2.6.29-rc1). Later on, this decision
612 turned out to be not ideal because we cannot have the feature compiled
613 in and disabled by default and let only interested to enable it
614 (e.g. general distribution kernels might need it). Therefore we have
615 added swapaccount[=0|1] parameter (introduced in 2.6.37) which provides
616 the both possibilities. If we remove noswapaccount we will have
617 less command line parameters with the same functionality and we
618 can also cleanup the parameter handling a bit ().

13303.5 Overriding Configuration for Special Cases 13353.5 Configuration with Interfaces Support
1336-----------------------------------------
1337
1338 This section applies to distros which use /etc/network/interfaces file
1339to describe network interface configuration, most notably Debian and it's
1340derivatives.
1341
1342 The ifup and ifdown commands on Debian don't support bonding out of
1343the box. The ifenslave-2.6 package should be installed to provide bonding
1344support. Once installed, this package will provide bond-* options to be used
1345into /etc/network/interfaces.
1346
1347 Note that ifenslave-2.6 package will load the bonding module and use
1348the ifenslave command when appropriate.
1349
1350Example Configurations
1351----------------------
1352
1353In /etc/network/interfaces, the following stanza will configure bond0, in
1354active-backup mode, with eth0 and eth1 as slaves.
1355
1356auto bond0
1357iface bond0 inet dhcp
1358 bond-slaves eth0 eth1
1359 bond-mode active-backup
1360 bond-miimon 100
1361 bond-primary eth0 eth1
1362
1363If the above configuration doesn't work, you might have a system using
1364upstart for system startup. This is most notably true for recent
1365Ubuntu versions. The following stanza in /etc/network/interfaces will
1366produce the same result on those systems.
1367
1368auto bond0
1369iface bond0 inet dhcp
1370 bond-slaves none
1371 bond-mode active-backup
1372 bond-miimon 100
1373
1374auto eth0
1375iface eth0 inet manual
1376 bond-master bond0

1378
1379auto eth1
1380iface eth1 inet manual
1381 bond-master bond0
1382 bond-primary eth0 eth1

1384For a full list of bond-* supported options in /etc/network/interfaces and some
1385more advanced examples tailored to you particular distros, see the files in
