|| ||[PATCH v2 0/7] can: CAN network device driver interface and drivers |
|| ||Tue, 12 May 2009 11:27:57 +0200|
|| ||Article, Thread
here comes v2 of the patch series posted some time ago. See
Changes since v1:
- The SysFS interface has been replaced by the Netlink interface as
suggested by Patrick. For further information have a look to
chapter 6.5 of "Documentation/networking/can.txt" and the header
file "include/linux/can/netdev.h". The patch for the "ip" program of
the iproute2 utility suite will be provided separately.
- The restart function is now properly protected by "dev->tx_lock"
using the "netif_tx_[lock|unlock]" functions.
- For the restart, the device driver must now handle CAN_MODE_STOP as
well, apart from CAN_MODE_START to avoid race conditions.
- The "irq_lock" member of "struct can_priv" has been removed. The CAN
controller driver may should provide its own synchronization if
- The restart function is now protected by "dev->tx_lock" using the
- Cleanup timer usage for the restart function.
- The unused do_set/get_ctrlmode member of "struct can_priv" have been
- "const" has been added to "struct net_device" for some functions not
allowed to touch that structure.
- The library functions "can_set_bittiming" and "can_close_cleanup" have
been renamed to the more general names "open_candev" and
- Use "del_timer_sync" instead of "del_timer" for the re-start timer.
- The macro "ND2D()" has been replaced by "dev->dev.parent" as it does
not make the code more readable.
- Fix improper BTR setting for triple-sampling for the SJA1000 as
pointed out by Oliver.
- Dont use __u8 but __u32 as before for some members of "struct
can_bittiming[_const]" to avoid alignment trouble.
- Definitions shared with user-space applications have been moved to
- Various other minor correction suggested on the netdev ML.
- The MSCAN driver for the MPC5200 has been removed. It needs to be
presented on the Linuxppc-dev and Devicetree-discuss ML as well,
which will be done by a sub-sequent patch.
- Add more source code documentation, especially for the structures
and functions related to bit-timing.
The PF_CAN protocol family for the Controller Area Network is available
in the kernel since version 2.6.25 but drivers for real CAN devices are
still missing. This patch series adds a generic CAN network device
driver interface and, as a start, a few drivers. It is the result of the
on-going discussion and development of the Socket-CAN project hosted at
the BerliOS web-server (http://developer.berlios.de/projects/socketcan).
The patch series consists of the following patches:
1/8) can: Documentation for the CAN device driver interface
2/8) can: Update MAINTAINERS and CREDITS file
3/8) can: CAN Network device driver and Netlink interface
4/8) can: Driver for the SJA1000 CAN controller
5/8) can: SJA1000 generic platform bus driver
6/8) can: SJA1000 driver for EMS PCI cards
7/8) can: SJA1000 driver for Kvaser PCI cards
