----------------------------------------

27 May 2004. Summary of changes for version 20040527:
|
||||
|
||||
1) ACPI CA Core Subsystem:
|
||||
|
||||
Completed a new design and implementation for EBDA (Extended BIOS
|
||||
Data Area) support in the RSDP scan code. The original code
|
||||
improperly scanned for the EBDA by simply scanning from memory
|
||||
location 0 to 0x400. The correct method is to first obtain the
|
||||
EBDA pointer from within the BIOS data area, then scan 1K of
|
||||
memory starting at the EBDA pointer. There appear to be few if
|
||||
any machines that place the RSDP in the EBDA, however.
|
||||
|
||||
Integrated a fix for a possible fault during evaluation of
|
||||
BufferField arguments. Obsolete code that was causing the
|
||||
problem was removed.
|
||||
|
||||
Found and fixed a problem in the Field Support Code where data
|
||||
could be corrupted on a bit field read that starts on an aligned
|
||||
boundary but does not end on an aligned boundary. Merged the
|
||||
read/write "datum length" calculation code into a common
|
||||
procedure.
|
||||
|
||||
Rolled in a couple of changes to the FreeBSD-specific header.
|
||||
|
||||
Code and Data Size: Current and previous core subsystem library
|
||||
sizes are shown below. These are the code and data sizes for the
|
||||
acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
|
||||
these values do not include any ACPI driver or OSPM code. The
|
||||
debug version of the code includes the debug output trace
|
||||
mechanism and has a much larger code and data size. Note that
|
||||
these values will vary depending on the efficiency of the
|
||||
compiler and the compiler options used during generation.
|
||||
|
||||
Previous Release:
|
||||
Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total
|
||||
Debug Version: 163.2K Code, 67.2K Data, 230.4K Total
|
||||
Current Release:
|
||||
Non-Debug Version: 77.7K Code, 11.5K Data, 89.2K Total
|
||||
Debug Version: 163.3K Code, 67.2K Data, 230.5K Total
|
||||
|
||||
|
||||
2) iASL Compiler/Disassembler:
|
||||
|
||||
Fixed a generation warning produced by some overly-verbose
|
||||
compilers for a 64-bit constant.
