Support
================================================================
If you have any problems you are welcome to contact us.
You will find the contact information on the web at
http://www.kvaser.com.


================================================================
Version info
================================================================

   * Tested under x86_64 SMP Ubuntu 14.04 x32/x64 (3.13.0-32-generic/3.13.0-32-generic).
   * Tested under x86_64 SMP Ubuntu 16.04 x32/x64 (4.4.0-generic/4.4.0-generic).
   * Tested under x86_64 SMP Ubuntu 18.04 x64 (4.15.0-38-generic).
   * Compiled with gcc version 4.6.3, 4.8.0, 5.4.0, 7.1.1, 7.2.0, 7.3.0 and 8.2.1.
   * Used glibc version 2.15, 2.17, 2.19, 2.24, 2.26, 2.27 and 2.28.


================================================================
General information
================================================================
System requirements: Linux 2.6.29 or later.

================================================================
Known problems
================================================================
   * Firmware bug in old Leaf firmware will make the driver report
     the wrong bus parameters when queried. Update the Leaf firmware.

   * Virtual CAN driver will not behave as it perhaps should when
     it is "off bus".

   * Single channel PCIcanII may report two channels.

   * It is possible to continue "using" a driver while it is
     trying to shut down. Nothing useful will happen, but the driver
     can be blocked from unloading indefinitely.

   * While the driver implements auto response functionality for all
     hardware, the same is not true for auto tx. The latter is only
     available if there is firmware support in the device.
     (This is the same as under Windows.)


New Features and Fixed Problems in V5.31   (24-FEB-2020)
===========================================================================
* Interchanged calls to canSetBusOutputControl() and canGetBusOutputControl()
  using CANlib and t is now consistent.

* Reverted a change regarding setting canDRIVER_NORMAL in v5.27 since this
  globally affected all channels. Calls to canSetBusOutputControl() and
  canGetBusOutputControl() is now persistent across all channels in the device
  until power is cycled in latest generation of devices (kcany, kcanf,
  kcanl). Older devices have not changed their behaviour.

* SDK (canlib)
  -Reading canCHANNELDATA_HW_STATUS will now return canERR_NOT_IMPLEMENTED
   instead of canERR_PARAM.

 -Capability SILENT_MODE is now reported for PCIcanx and PCIcanx II devices.

* Added support for new device:
  - KVASER U100 (01173-1)
  - KVASER U100P (01174-8)


New Features and Fixed Problems in V5.30   (08-OCT-2019)
===========================================================================
* Minor changes.


New Features and Fixed Problems in V5.29   (13-SEP-2019)
==========================================================================
* SDK (canlib)
  - The message data buffer is untouched when reading a remote request frame
    as identified by the canMSG_RTR flag.
  - canGetBusStatistics reports the same result if transmit acknowledge is
    off (0) or on (1). Transmit acknowledge is set by ioctl canIOCTL_SET_TXACK.
  - Fixed a bug in kvFileCopyToDevice.

  - Implemented the following tScript functions:
    kvScriptStatus and kvScriptLoadFileOnDevice.
    kvScriptEnvvarOpen and kvScriptEnvvarClose.
    kvScriptEnvvarSetInt and kvScriptEnvvarGetInt.
    kvScriptEnvvarSetFloat and kvScriptEnvvarGetFloat.
    kvScriptSendEvent.
    kvScriptGetText and kvScriptRequestText.

* SDK (kvlclib)
  - Fixed a bug that, when a frame didn't have any signals in the dbc-file,
    signal-names from other frames wheren't printed out.
  - Added API function kvlcEventCountEx, handling the situation where the number
    of events exceeds the size of an int.

* SDK (kvadblib)
  - Added API function GetLastParseError. Call GetLastParseError to get more
    information if kvadblib encounters format issues when loading a database
    from file.
  - Fixed a bug where non J1939 frames was faulty determined as J1939 frames.
  - Improved the behaviour when reading certain .dbc files with syntax errors
    so as not to cause crashes.
  - Flag KVADB_MESSAGE_J1939 is now set for J1939 frames in
    call to kvaDbGetMsgFlags.

* SDK (kvmlib)
  - Added API functions kvmLogFileGetType.
  - Added API functions kvmLogFileMountEx and kvmKmeCountEventsEx,
    handling the situation where the number of events exceeds the size of an int.

* Common
  - fixed bug where a call to canIOCTL_TX_INTERVAL could cause a crash if
    TX_INTERVAL is unsupported by the device.
  - BusStatistics increments between calls to canGetBusStatistics. Previously,
    it was cleared. The function now has the same behavior as in Windows.

* PCIEcan
  - Implemented canGetBusStatistics for reading the busload value.
  - BusStatistics now separates correctly on standard and extended id frames.


New Features and Fixed Problems in V5.28   (12-MAY-2019)

  useful when connecting PCIEcan via PCI-to-PCIe bridge.

* Added warning when building on host with Secure Boot enabled.

* Updated doc/faq.


New Features and Fixed Problems in V5.26   (26-NOV-2018)
===========================================================================
* Updated the README and "General information" in this document. Since linuxcan
  version V5.12 the minimum Linux kernel version required is 2.6.28. For pciefd
  driver 2.6.29 is required.

* Fixed bug with corrupt serial numbers in PCIcan driver.

* Fixed build problems for GCC 8 and old GCC (4.3 and 4.6).

* SDK (canlib)
  - Fixed a bug where handles became invalid for a short while when
    connecting 2 or more usb-devices that used the same driver.

    going onbus.

  - Implemented canNOTIFY_BUSONOFF.

* SDK (kvlclib)
  - Added Vector MDF .log input format.
  - Added API to access information about reader formats.
  - Added option KVLC_PROPERTY_FULLY_QUALIFIED_NAMES to enable use of fully qualified
    signal names when converting log files to output format "selected signals in CSV format".
  - Added number of data decimals property for csv-format. Default value is 4.

* SDK (kvmlib)
  - Fixed a bug where kvmLogFileReadEvent() returned kvmERR_FILE_ERROR
    and not kvmEOF after the last event.

* Corrected timeGetTime in linlib.


New Features and Fixed Problems in V5.19   (15-FEB-2017)
===========================================================================

* The reported frame-id in the callback for canSetNotify is now
  correct when using extended-id.

* The reported event in the the callback for canSetNotify is now
  correct.

* Fixed bug in canReadSyncSpecific where extended identifiers was not
  recognized.

* Removed dependency, so calling 'sudo make install' and 'sudo make load' will
  not rebuild drivers, canlib, linlib nor example code.

* File access modes for installed files have been reviewed.

* Added new APIs:
  - kvFlashLeds.
  - kvReadTimer and kvReadTimer64.
  - canUnloadLibrary. It uses non-portable initialization of mutex (works on
    Linux only).

* Fixed bug when reading customized channel names, causing oops.

* Corrected data exchange between user space and kernel space, for ioctl.

* Fixed problem in makefile when building on openSUSE with kernel older than
  v3.18.0.

* The linlib shared object is now compiled with -lcanlib to declare the
  dependency toward canlib.

* Change canBusOn and canBusOff behavior, to match Windows. It is required to
  call canBusOn (and canBusOff) for each handle, even though they share same
  physical channel. Could potentially be a breaking change.
  See Kvaser canlib documentation for details.


New Features and Fixed Problems in V5.18   (28-SEP-2016)
===========================================================================
* Fix for Leaf incompatibility issue with Leaf FW older than version 3.8.


New Features and Fixed Problems in V5.17   (15-SEP-2016)
===========================================================================
   * Added Single shot functionality.

   * Added dummy canRequestChipStatus for code portability. The function
     canRequestChipStatus is not needed in Linux, but in order to make code
     portable between Windows and Linux, a dummy function returning canOK has
     been added.

   * Added support for reading out customized channel names for mhydra, pciefd
     and leaf (currently it is only possible to set customized channel names
     from Windows).

   * Added canReadSpecific, canReadSpecificSkip and canReadSyncSpecific.

   * Added canRequestBusStatistics and canGetBusStatistics.

   * Added canIOCTL_RESET_OVERRUN_COUNT.

   * Added make target 'uninstall' which unloads all Kvaser modules and
     removes entire Kvaser installation.
     It is possible to uninstall each individual driver, but it is not
     recommended. The usb based drivers uses the common udev rules
     (10-kvaser.rules) file to load and unload modules which remains
     until one executes 'sudo make uninstall'.

   * Added make target 'load'  which does the same as target 'install' and
     then loads all PCI modules also after reboot.

   * Leaf and Eagle devices now also defaults to canDRIVER_NORMAL.

   * Improved handling of illegal input parameters.

   * All canlib example code is reviewed and updated.

        - Kvaser Leaf Pro HS v2      (00843-4)
        - Kvaser USBcan Pro 2xHS v2  (00752-9)

    * Replaced Windows types with stdint types.

    * Added support for canGetHandleData.

    * Added canCHANNELDATA_CHANNEL_CAP_MASK to read which capabilities are
      confirmed dynamically by device.

    * Implemented canIOCTL_TX_INTERVAL, canIOCTL_SET_BRLIMIT and
      canCHANNELDATA_MAX_BITRATE.

    * Removed obsolete USB hotplug support.

    * Fixed bug, where return value of canIOCTL_GET_RX_BUFFER_LEVEL was affected
      by transmit buffer length.


New Features and Fixed Problems in V5.15   (07-MAR-2016)
===========================================================================
   * No changes, this is a companion release to the Windows version.


New Features and Fixed Problems in V5.14   (01-MAR-2016)
===========================================================================
   * A bug regarding maximum number of channels for a kernel module (MAX_CHANNELS)
     has been fixed for all drivers.

     match canReadTimer().


New Features and Fixed Problems in V5.13   (15-DEC-2015)
===========================================================================
   * Updated pciefd driver to work without DMA (option USE_DMA in
     pciefd_config.h). Note, however, that this is an unupported (and
     consequently untested) feature that may break in the future.

New Features and Fixed Problems in V5.12   (21-SEP-2015)
===========================================================================
   * Sampling points of default CAN bitrates are now 75% instead of 62.5%.

     Light 4xHS, Leaf Pro HS v2, KVASER USBcan Pro 2xHS v2, KVASER Memorator
     2xHS v2, Memorator Pro 2xHS v2.

   * Improved support for CAN-FD for PCIEcan 4xHS.

   * Kvaser device drivers now all use a common driver (kvcommon) that is
     loaded seprarately.

   * Updated register names and definitions in PCIEcan driver to comply with
     the names used in the ISO standard for CAN-FD.

   * Kvaser PCIEcan 4xHS requires firmware 2.0.1 or higher.

New Features and Fixed Problems in V5.11   (21-MAY-2015)
===========================================================================
   * Blacklisting SocketCAN kvaser_usb driver when installing leaf and usbcanII
     drivers.
