| 227 May 2004. Summary of changes for version 20040527:
3
41) ACPI CA Core Subsystem:
5
6Completed a new design and implementation for EBDA (Extended BIOS
7Data Area) support in the RSDP scan code. The original code
8improperly scanned for the EBDA by simply scanning from memory
9location 0 to 0x400. The correct method is to first obtain the
10EBDA pointer from within the BIOS data area, then scan 1K of
11memory starting at the EBDA pointer. There appear to be few if
12any machines that place the RSDP in the EBDA, however.
13
14Integrated a fix for a possible fault during evaluation of
15BufferField arguments. Obsolete code that was causing the
16problem was removed.
17
18Found and fixed a problem in the Field Support Code where data
19could be corrupted on a bit field read that starts on an aligned
20boundary but does not end on an aligned boundary. Merged the
21read/write "datum length" calculation code into a common
22procedure.
23
24Rolled in a couple of changes to the FreeBSD-specific header.
25
26Code and Data Size: Current and previous core subsystem library
27sizes are shown below. These are the code and data sizes for the
28acpica.lib produced by the Microsoft Visual C++ 6.0 compiler, and
29these values do not include any ACPI driver or OSPM code. The
30debug version of the code includes the debug output trace
31mechanism and has a much larger code and data size. Note that
32these values will vary depending on the efficiency of the
33compiler and the compiler options used during generation.
34
35 Previous Release:
36 Non-Debug Version: 77.6K Code, 11.5K Data, 89.1K Total
37 Debug Version: 163.2K Code, 67.2K Data, 230.4K Total
38 Current Release:
39 Non-Debug Version: 77.7K Code, 11.5K Data, 89.2K Total
40 Debug Version: 163.3K Code, 67.2K Data, 230.5K Total
41
42
432) iASL Compiler/Disassembler:
44
45Fixed a generation warning produced by some overly-verbose
46compilers for a 64-bit constant.
