25 September 2003      CPSAR 1.6.6 (external release)

CC Labels: REL_20030925_HALdallas_cpsar_01.06.06

Bug fixes:   PDSP firmware has been updated to fix the OAM padding problem.  It previously
             wrote pad bytes into a reserved field of the OAM cell.  There is a small
             change to the CPSAR configuration code which corresponds to the PDSP spec
             change.

05 August 2003         CPHAL 1.6.5 (external release)

CC Labels: REL_20030805_HALdallas_cpmac_01.06.05

Bug fixes: NTR

New features:  CPMAC : Added support for CPMAC modules that do not have a Phy connected.
               The CPMAC is informed of this by the MdioConnect option
               _CPMDIO_NOPHY. This is the only driver change needed to
               receive and transmit packets through the Marvel switch.
               Note  In this mode Link status will reported linked at 100/FD to
               PhyNum 0xFFFFFFFF.

               ALL:  Cleaned up some Vlynq support logic.

16 July 2003         CPSAR 1.6.3 (external release), no CPMAC release

CC Labels: REL_20030716_HALdallas_cpsar_01.06.03

Bug fixes: 1) Changed default value of CPCS_UU from 0x5aa5 to 0.  The old default value caused
              problems with Cisco routers.

New features:  NTR

01 July 2003         CPHAL 1.6.2 (external release)

CC Labels: REL_20030701_HALdallas_cpmac_01.06.02
           REL_20030701_HALdallas_cpsar_01.06.02

Bug fixes: 1) A previous firmware upgrade caused firmware OAM loopback cells to only work on every other
              command.  This has been fixed in the new firmware version (0.47).
           2) Problem with PTI values changing on transparent mode packets has been resolved.
           3) Previously, successful firmware OAM loopback cells waited 5 seconds before notifying the
              OS of success, rather that notifying immediately.  This has been resolved in firmware.
           4) PITS #148 (MAC and SAR), #149 (MAC) have been fixed.

New features: 1) AAL5 HAL now capable of receiving unknown VCI/VPI cells on a single transparent channel.
                 See updated HAL document (AAL5 appendix) for implementation details.
              2) AAL5 HAL now allows OS to modify the OAM loopback timeout window.  Previously, failed
                 OAM loopback attempts timed out after a nominal 5 seconds (based on the SAR frequency
                 provided by the OS).  Now, the default is 5 seconds, but the OS may change the
                 value via halControl() to any integer number of milliseconds.  See updated HAL document
                 (AAL5 appendix) for implementation details.
              3) MAC (cpmdio): added loopback to Istate.  Used for debug.

Known issues not addressed in this release: NTR.

09 June 2003         CPSAR 1.6.1 (external release), CPMAC 1.6.1 (internal release - no functional change)

Note: This is the same set of fixes being applied to 1.6.0 that were applied to 1.5.3.  The only difference
      between 1.6.1 and 1.5.4 is that 1.6.1 has the TurboDSL fix.

           REL_20030530_HALdallas_cpsar_01.05.03

Bug fixes: NTR.

New features: 1) AAL5 Send() has been modified to accept an ATM Header either in the first
                 fragment by itself, or in the first fragment directly in front of payload data.
                 The API() does not change.
              2) Documentation updates throughout, reflected in latest version of CPHAL user's
                 guide.
              3) AAL5 MaxFrags default value is now 46.  This is based upon the default AAL5
                 RxBufSize of 1518 (MaxFrags = (65568/1518) + 2).  IF THE OS CHOOSES A SMALLER
                 RxBufSize, IT MUST INCREASE THE VALUE OF MaxFrags ACCORDINGLY.  This is done
                 via halControl(), prior to Open().

Known issues not addressed in this release:
              1) The Linux SAR driver is seeing an issue in which it cannot
                 reliably send traffic simultaneously on both the high and
                 low priority queues of a single AAL5 channel. (TurboDSL)

           REL_20030523_HALdallas_cpsar_01.05.02

Bug fixes: 1) PITS #138: CPMAC flooding issue resolved.
           2) PITS #142: OS may now set "MaxFrags" via Control().  This controls the
              maximum number of fragments expected by the CPHAL.  The default value is 2 for
              CPMAC and 1028 for AAL5.  If the OS chooses a RxBufSize that will cause more
              fragments than the defaults, the OS must set "MaxFrags" to a correct value
              ((maximum packet length / RxBufSize) + 2).
           3) PITS #143: Fixed.
           4) Firmware OAM bug fixed. (new firmware release in this version)

           REL_20030514_HALdallas_cpsar_01.05.01

Bug fixes:    1) PITS 132 - (CPMAC) Frames < 60 bytes and split into
                             multi-fragments.
              2) BCIL MR PSP00000353 - (CPMAC) PhyDev not free'd on halClose()
              3) PITS 113 - OsSetup bug in ChannelSetup fixed.
              4) Fixed AAL5 to check return values of InitTcb/InitRcb.
              5) Fixed Shutdown to properly free resources in the case of a Close
                 mode 1 followed by Shutdown.  Previously, buffer and descriptor
                 resources were left unfreed in this case.

New features: 1) AAL5 Send() modified to be capable of accepting ATM header as first four
                 bytes of first fragment.  This allows the OS to "override" the
                 default ATM header which is constructed from preconfigured channel
                 parameters.
              2) AAL5 Receive() modified to be capable of passing the received ATM header (4 bytes, no HEC)
                 in the first fragment (by itself).  It also passes up the OS an indication
                 of what the received packet type was.  For Host OAM and transparent mode
                 packets, the ATM header is passed in this manner, and for other types of packets
                 (AAL5, NULL AAL) no ATM header is passed currently.

Known issues not addressed in this release:
              1) The Linux SAR driver is seeing an issue in which it cannot

           REL_20030430_HALdallas_cpsar_01.05.00

Bug fixes:   1) Fixed AAL5 bug that rendered the low priority queue
                unusable.
             2) Fixed a bug in AAL5's Oam Rate calculations.
             3) Fixed use of "DeviceCPID" key in AAL5's halControl().
             4) Fixed RxReturn logic in HAL.  The HAL now can handle
                failing MallocRxBuffer calls when multiple fragments
                are being used.

New features: 1) AAL5 Stats now available on a per queue basis.
              2) AAL5 adds two new keys to halControl() for "Set" actions:
                 RxVc_OamCh and RxVp_OamCh.
              3) Shutdown() has been modified for both AAL5 and CPMAC to
                 call Close() if the module is still in the Open state.
              4) CPMAC adds the following access keys to halControl():
                 hcPhyAccess,hcPhyNum,hcCpmacBase,hcSize,and hcCpmacSize.
              5) CPHAL no longer requests an extra 15 bytes on data buffer
                 mallocs.

Known issues not addressed in this release:
              1) The Linux SAR driver is seeing an issue in which it cannot

           REL_20030421_HALdallas_cpsar_01.04.01

Bug fixes:   1) Fixed OAM logic in SAR portion of CPHAL.

New features: 1) OAM loopback counters exposed through halControl.
              2) Host OAM Send() can now use a single channel to send
                 OAM cells on unlimited number of VP's/VC's.
              3) CPHAL now requests "SarFreq" through osControl.
              4) CPHAL now calculates all OAM function rates based on
                 "SarFreq"; function OamRateConfig removed for API.
              5) New OAM function OamLoopbackConfig, used for configuring
                 loopback functions in firmware OAM mode.

Known issues not addressed in this release:  Bug fix 1) in release 1.4
             (see below) does not work properly for multiple fragments.

           REL_20030410_HALdallas_cpsar_01.04.00

This release is for SAR and MAC.

  Bug fixes: 1) Implemented logic in HAL to re-request buffer mallocs
                in the case of MallocRxBuffer failing.  The HAL now maintains
                a NeedsBuffer queue of all RCB's that are without buffers.
                On interrupts, or on Send(), the HAL checks to see if any
                RCB's are on the queue, and if so, calls MallocRxBuffer
                to attempt to get a new buffer and return the RCB to
                circulation.
             2) SAR now properly returns all error codes from halOpen and
                halChannelSetup.

  CC Labels: REL_20030408_HALdallas_cpsar_01.03.01

  This is a SAR only release.  The current CPMAC release is still 1.3.

  Bug fixes: 1) PDSP State RAM / Scratchpad RAM is now completely cleared after reset.
                This resolves a stability issue.

  New features: 1) OamMode is now a parameter in halControl().  Both "Set" and "Get"
                   actions are available.  The value may be "0" (Host OAM), or "1"
                   (Firmware OAM).

  Known issues not addressed in this release:
             1) Appropriate action for HAL in the case of MallocRxBuffer failing.  We
                are investigating whether the HAL should implement a needs buffer
                queue.

             REL_20030404_HALdallas_cpaal2_01.03.00

  This release requires no changes for the ethernet end driver.  The changes necessary
  for the sar driver (firmware file name changes) have already been implemented.

  Bug fixes: 1) RxReturn now returns an error if MallocRxBuffer fails.  On RxReturn error, the driver should
                call RxReturn again at a later time (when the malloc may succeed) in order for the CPHAL
                to maintain a full complement of Rx buffers.  We recommend holding off making this driver
                change until we verify that this condition occurs.

  New features: 1) Removed benign compiler warnings.
                2) PITS 122: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=122
                3) Cpsar label (above) now is applied to everything
                   beneath /cpsar.
                4) PITS 14: http://www.nbu.sc.ti.com/cgi-bin/pits/redisplay_archive?product=cphal_dev&report=14
                   Transferred to MR PSP 00000089.
