changelog

can4linux-3.5.3.gz can4 linux

3.5.3 - For some reasons, parameter location changed from
	/proc/sys/Can/* to /proc/sys/dev/Can/*
      - support for CAN_MAX_OPEN for the ATMEL AT91SAM9263
      - common code base now for most CAN chips supported
      - support for the new CPC_PCI with up to four CAN controllers
      	still preliminary, need to combine the _old_ and _new_
      	in any combination
      - new TARGET=MMC_SJA1000, ARM AT91SAM9269 with 3 external
        SJA1000 with multiplexed memory access.
      - new TARGET=SSV_MCP2515
3.5.2 - More than one process can now open the driver
	This number is defined at compile time.
	Can be set in the Makefile or in defs.h 
	e.g. CAN_MAX_OPEN=4
	This feature is currently on the sja1000 only supported
	and only tested with the CPC-PCI interface

      - ioctl return value changed to 0 on successful return
	extended selfreception flag from 'per channel (minor)' to
	  'per process'
      - prohibit setting a new bitttime if the channel was already opened
	  by another process, setting the same bitrate as the first
	  process is permitted
      - this version should at least compile up to kernel 2.6.22
	testet on 2.6.22 quad core
3.4.6 - udev support
3.4.5 - Tested on SMP and 64 Bit X86 machines
	made some 64 bit type adoptions
3.4.4 - removed Bug in mcf5282 when transmitting from ISR
3.4.3 - removed warnings
	ignoring return value of 'copy_to_user'
	with kernel version 2.6.16.21
      - introducing general DEFS compiler settings.
	used for e.g. -Wno-undef
3.4.2 - Support for EMS CPC-104 (PC104 containing SJA1000)
        changed type of can_base[] to __iomem (contains virtual address)
3.4.1 - bug in mcf5282 interrupt handling which selfreceived messages 
        removed
3.4   - new release with changing the directory structure 
        all files without can_ prefix, because we are in the can4linux
        sub directory
      - read() and write() are now blocking per default
      - getting the time stamp information for received messages
        in canmsg_t can be switched off if not needed
        (saves some us ISR time)
      - supported controllers and CAN interface boards now additional:
        Kvaser PCIcan-Q 
        MPL VCMA9 
        Analog Devices BlackFin 537
        Freescale 5282

3.3.6 - read() is now a blocking read if not opened with O_NONBLOCK
3.3.5 - new ioctl() direkt setting of BTR registers
	each value is possible now using this ioctl()
3.3.4 - two new ioctl() configuration commands for sja1000 devices
	self reception mode - each message sent is delivered back
	      in the rx queue
	listen only mode (CAN controller doesn't acknowledge frames)
3.3.3 - removed cli()/sti() code sections
      - use __iomem 	

3.3 - can4linux for LINUX Kernel build 2.6 in new directury
      more simple directory structure and using the kernel module build

3.2 - Changed Structures compatible between all hardware variants
      Modified and extended to support Generic i82527 cards and
      the SBS PC7compact DINrail mounted industry PC
      by FOCUS Software Engineering Pty Ltd <www.focus-sw.com>

3.1 - Added support for SSV TRM/816 by Sven Geggus <[e-mail]>
      new hardware configuration CAN_INDEXED_PORT_IO used on Elan
    - updated examples (esp. can_send.c to new 3.0 CanStatusPar_struct.

3.0 - going further into compiling the driver directly for the hardware
      specified in Makefile
      Removing old code
        - the old 82cC200 is not longer supported
          only sja1000 in PeliCAN mode
        - begin canceling support for OS < 2.4.0
      new pci detection code, using improved linux pci bios features
      PCI cards should be detected in other PCI busses as 0 as well
      - Changed the CanSja1000Status_par_t to a more generic one 
        CanStatusPar_t

2.6 - 2.5 had a very serious bug. Because of wrong index definitions into
      the Sysctl array, it was possible to set the Base address and IRQ
      to 0 when using the CPC-PCI board

2.5 - removed bug in can_ioctl(); thanks to [e-mail]
      Suport for Advantech Pcm-3680

2.4 - because the driver must be compiled for a specific TARGET
      now some "configuration" values are preset at compile time:
      IOModel, Outc, VendOpt.
      nevertheless, Outc can be overwritten
    - Makefile checks for supported TARGET


2.3 - /proc/sys/CAN/version now contains also the target name can4linux
    is compiled for
    - ioctl() get status returns additional the size and 
      number of rx and tx messages in buffers
    - improved tx buffer handling 
    - Support I+ME PcSlimLine ISA card with SJA1000

!!!!!!!!
2.2 - may be somethg wrong with this version with the CPC-PCI support !!!!
!!!!!Unterst.Controller: SJA1000
     Karten: ATCANMINI_BASIC, ATCANMINI_PELICAN
	CPC_PCI, IXXAT_PCI03
 
2.1 - freigegeben
     2.0 - (nicht released)
     erste Version abger黶tet,
     躡ersetzbar ohne LDDK und nur f黵 einen Controller-typ,
     bzw. Kartentyp, Ausw鋒lbar zur Kompile-Zeit,
     dadurch f黵 embedded Systeme verwendbar (ben鰐igt weniger Speicher)
