ChangeLog for the EDT PCI 53B software/driver package
=====================================================

For LINUX device drivers, see CHANGELOG_LINUX.txt

version 4.1.6.5

Change all direct register writes to write-readback to correct problem
with some computers showing errors from embselect.

version 4.1.5.4, 4.1.5.5

Aggregate changes in common EDT driver code, tested for production release.

  Host driver changes:

    Lint changes:	Add prototypes and typecasts and removed unused
    			declarations to eliminate compiler warnings.

			Strengthened debugging, removed unwanted debugging.

			Removed last argument to Astro_msg_to_idx() call.

    Bugfixes:		RT message queue locking fixed.

    			Corrected uninitialized driver variable embtype.

			RT wait mask handling fixed.

			Driver memory allocation and free fixed, plus disable
			board interrupts during free.

    Portability:	AMD64 Solaris adjustment.


  Embedded SPARC changes: 

    Optimization:	Move embedded SPARC variables to local from shared
    			with host.

    Bugfixes:		Fix BC_AUTO continue function.

			Fix SCHED_HW handshake.

			Correct customer-specific process_bc() function
			behaviour.

version 4.1.4.4

1. Fixed a bug in p53b_intr_rt() where xmt_actualmask was assigned
   the value of an uninitialized variable (tmpmask).


version 4.1.4.3
Production release

version 4.1.4.2

1. Fixed a bug in the S_MODECODE ioctl() where an interrupted
   return from kernel sleep goes into a tight loop calling
   kernel sleep because retval is not checked and exit condition
   never occurs.  Fix by checking return value and breaking out
   if EINTR is true.

2. Fixed a race condition where different 1553 entities
   (RTs, BC, BM) are stomping on each other while communicating
   with the embedded SPARC.  Fix by requiring critical section
   around code that communicates with embedded sparc, thus serializing
   access.

3. Fixed a bug in the Bus Monitor resulting from a race condition;
   when the BM is first opened, communication with the embedded SPARC
   must be allowed to complete before using the BM.  Changed libp53b.c
   to sleep for 1 second (much more than required) when opening a BM.
