It’s name is actually FoldedViewer (no trademark infrignment intended if any)
and the JS/ HTML5 program is useful for speeding up analys of DSDT/ SSDT tables
by providing folding capabilities. If you’re using a recent browser, especially
if it’s open-source like Firefox or Chromium, you’ll be able to select files
through a file picker.
fieldsize.c
Compile with gcc -Wall fieldsize.c -o fieldsize
.
Run ./fieldsize and paste the contents from Field
s in it and it’ll display
the fields with the offset on the end of the line. Whitespace is ignored.
Only lines starting with NAME, [numeric value],
, AccessAs
and
Offset ([numeric/hex value]),
are recognized, all other input will cause
the program halt with a fatal error. Parsing stops on EOF (Ctrl + D)
Example input (stdin):
Offset (0x8C),
SVID, 16,
SSID, 16,
Example output (stdout):
Offset (0x8C), // byte 0x8C bit 0
SVID, 16, // byte 0x8C bit 0
SSID, 16, // byte 0x8E bit 0
get_methods
Retrieve the ACPI methods from an AML file (e.g. from acpidump). Usage:
get_methods DSDT.dat SSDT.dat more.dat etc...
methods_tree
A PHP script for converting the output of get_methods
to a HTML document.
Example usage:
./get_methods {DSDT,SSDT*}.dat | ./methods_tree > out.html
acer_ec.pl
Retrieved from
http://aceracpi.googlecode.com/svn/trunk/acer_ec/acer_ec.pl
