RE: [PATCH] Acpica-20030619 and "-g" option

[Grover, Andrew]

Hi Hrvoje,

Well that's what I get for replying to 2 week old email without reading
everything first. Glad to see you took up the challenge.

However, it should be possible to add this support without modifying any
files *except* osunixxf.c. I don't mean to be too demanding but if you
wouldn't mind considering that approach, I'd appreciate it.

Thanks -- Regards -- Andy

I could try ... should i work on 20030619 or there is a newer version?

In what state is CVS version? Stable enough? Which branch to "export"?

[PATCH] acpica-20030714 and "-g"

[Hrvoje Habjanic]

[-- Attachment #1: Type: text/plain, Size: 1401 bytes --]


Hi all!

As you all noticed, "-g" isn't working in latest acpica release. I've managed 
to fix that.

BUT - it can be fixed in two ways:

1. (which i preffer) Using built-in acpi helper functions (tables/* directory)
 - advantages - hopefully, in this way you know what to expect when you 
"unleash" these functions/subs in real kernel on real machine
- disadvantages - everything stays complicated ;-)

2. to copy/paste all important things to osunixxf.c
 - advantages - all important parts in one place
 - disadvantages - code in osunixxf.c and tables/* CAN get out-of-sync, and 
maintaining is more complicated

So, i've decided to go with (1).

Changed files:
common/adisasm.c
compiler/aslstubs.c
compiler/Makefile
osunixxf.c

Changes in adisasm.c are from replacing AcpiOverrideTable*. 

(Andy, i know that it would be "nicer" to put everything in osunixxf.c, but 
use of AcpiOverrideTable is, among other things, causing circular calling. It 
becomes quite complicated to write "clean" code. I think that suggested 
modifications are minimal, and they make disassembler work more like some 
kernel based on this code.)

Still, there is room for improvements, so ....

And another note; currently SSDT tables ONLY get saved, and not disassembled. 
It would be nice to get them disassembled (maybe someone with more knowledge 
of this code/parsing ...)

Hrvoje

Hi Hrvoje 
Can you do the same patch for acpica-20030918 ?

at least read the RSDT ? :)

[PATCH] Acpica-20030619 and "-g" option

[Hrvoje Habjanic]

[-- Attachment #1: Type: text/plain, Size: 468 bytes --]


Well, hello again ... ;-)


After few hours of grep/vi/grep , i've finally made this to work (that is, 
./iasl -g to dump DSDT tables).

Looking at it now, it seems very easy - mmap-ing memory was the most trickier 
part because of page aligement ....

Patch is attached ... it will work on x86 (32bit) - for others - i'm not 
shure.

And another thing. It currently dumps ONLY DSDT table, but, i think it could 
be nice to dump all tables ... maybe later.


Hrvoje
