The driver mapped only 128 bytes of the CAN controller address space when a CPC-PCI v2 was detected (incl. CPC-104P). This patch will fix it by always mapping the whole address space (4096 bytes on all boards) of the corresponding PCI BAR.

When using nanosleep() in an userspace application we get a ratelimit warning NOHZ: local_softirq_pending 08 for 10 times. The echo of CAN frames is done from process context and softirq context only. Therefore the usage of netif_rx() was wrong (for years). This patch replaces netif_rx() with netif_rx_ni() which has to be used from process/softirq context. It also adds a missing comment that can_send() must no be used from hardirq context.

This patch adds support for legacy SJA1000 CAN controllers on the ISA or PC-104 bus. The I/O port or memory address and the IRQ number must be specified via module parameters: insmod sja1000_isa.ko port=0x310,0x380 irq=7,11 for ISA devices using I/O ports or: insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 for memory mapped ISA devices. Indirect access via address and data port is supported as well: insmod sja1000_isa.ko port=0x310,0x380 indirect=1 irq=7,11 Here is a full list of the supported module parameters: port:I/O port number (array of ulong) mem:I/O memory address (array of ulong) indirect:Indirect access via address and data port (array of byte) irq:IRQ number (array of int) clk:External oscillator clock frequency (default=16000000 [16 MHz]) (array of int) cdr:Clock divider register (default=0x48 [CDR_CBP | CDR_CLK_OFF]) (array of byte) ocr:Output clock register (default=0x18 [OCR_TX0_PUSHPULL]) (array of byte) Note: for clk, cdr, ocr, the first argument re-defines the default for all other devices, e.g.: insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 clk=24000000 is equivalent to insmod sja1000_isa.ko mem=0xd1000,0xd1000 irq=7,11 \ clk=24000000,24000000 Signed-off-by: NWolfgang Grandegger <wg@grandegger.com> Tested-by: NOliver Hartkopp <oliver@hartkopp.net> Signed-off-by: NDavid S.

For 'real' hardware CAN devices the netlink interface is used to set CAN specific communication parameters. Real CAN hardware can not be created with the ip tool ... The invocation of 'ip link add type can' lead to an oops as the standard rtnl newlink function was called: http://bugzilla.kernel.org/show_bug.cgi?id=13954 This patch adds a private newlink function for the CAN device driver interface that unconditionally returns -EOPNOTSUPP.

This patch adds a generic driver for SJA1000 chips on the OpenFirmware platform bus found on embedded PowerPC systems. You need a SJA1000 node definition in your flattened device tree source (DTS) file similar to: can@3,100 { compatible = "nxp,sja1000"; reg = <3 0x100 0x80>; interrupts = <2 0>; interrupt-parent = <&mpic>; nxp,external-clock-frequency = <16000000>; }; See also Documentation/powerpc/dts-bindings/can/sja1000.txt.

As discussed on the netdev mailing list, the member "base_addr" of "struct net_device" should not be (mis)used to store the virtual address to the SJA1000 register area. According to David Miller, it's only use is to allow ISA and similar primitive bus devices to have their I/O ports changed via ifconfig. The virtual address is now stored in the private data structure of the SJA1000 device and the callback functions use "struct sja1000_priv" instead of the unneeded "struct net_device".

The CAN network device driver interface provides a generic interface to setup, configure and monitor CAN network devices. It exports a set of common data structures and functions, which all real CAN network device drivers should use. Please have a look to the SJA1000 or MSCAN driver to understand how to use them. The name of the module is can-dev.ko. Furthermore, it adds a Netlink interface allowing to configure the CAN device using the program "ip" from the iproute2 utility suite.
