TESTING STATUS OF THIS RELEASE
All AAL1GATOR-32 device driver Application Programming Interface (API) functions have been tested in-house using the PM73122 on a proprietary PMC-Sierra, Inc. application platform running VxWorksTM RTOS. As of the publication date of this document, there are no known bugs in this release. However, the customer is advised to consult our web site (http://www.pmcsierra.com) for any relevant errata that may have been issued subsequent to the publication of this document.

DEVICE ERRATA SOFTWARE WORKAROUNDS
This driver implements software workarounds for the Revision A device errata which, depending on the revision code of the AAL1gator device as read by the initialization routines, will be automatically enabled (Rev A) or disabled (Rev C). An option exists for those users who are only using Revision C devices to compile the driver without any workaround code by using the compile switch, "AL3_CSW_DISABLE_ALL_WORKAROUNDS". The only benefit of doing this is a reduction in the size of the compiled code. There are no workarounds required for Revision C devices. There are, however, some DBCES limitations in Revision C devices. The reader is referred to PM73122 Revision C Device Errata (PMC-2011072) for further details. The following describes the workarounds implemented for Revision A device errata. The reader is referred to PM73122 Revision A Device Errata (PMC-2000421) for further details. * SRTS Queue Underrun Impacts Other Lines in A1SP - When using the Synchronous Residual Time Stamp (SRTS) scheme in Unstructured Data Format (UDF) mode, the buffer that contains received SRTS nibbles underruns for a specific line. A signal is sent to the internal clock synthesizer (CGC) that indicates that all the lines are in SRTS underrun. This causes all lines within an A1SP block to revert to normal clocking. In order to prevent this problem, the driver defers enabling of the SRTS bit until the SRTS queue is active and not in the underrun state. The initialization of this workaround is in the aalInitRegsLine() (file: al3_init.c) and the active switching of the SRTS bit is in aalCoreDPR() (file al3_dpr.c). (This problem is only present on unstructured lines)

AAL1GATOR-32 (PM73122) Device Driver Release Notes
*
LOW_CDV Queue Does Not Activate/Deactivate Correctly - For Unstructured Data Format (UDF) lines there is a LOW_CDV bit which can be set in the LIN_STR_MODE memory register which will cause cells to be scheduled every 47 bytes instead of every frame. This eliminates the CDV caused by the scheduler. This mode can only be used in UDF-ML mode when BYTES_PER_CELL is 47. In High Speed mode cells are always scheduled every 47 bytes which assumes that partial cells are never used in HS mode. If a queue is "added" to the ADDQ_FIFO and LOW_CDV is set, data errors may result because the FRAMES_PER_CELL field is defaulted to a 1 instead of 2. Also if a queue is deactivated by clearing the ACTIVE bit when LOW_CDV is set, the CSD can enter a lock condition. In order to prevent this problem, the driver always adds and deletes queues with the LOW_CDV bit cleared and the SUPPRESS_XMT bit set. The workaround is in aalActivateQueueUnstr() (file: al3_chan.c). (This problem is only present on unstructured UDF lines)
