| hi, I have copied DSDT and FADT from /proc/acpi to files, and suppose this could be one way to get the data I was asking about. Now, I don't know what these tables are in fact. ( attempting to figure out some of that now ) Found some decompiler and issued iasl -d fadt.dat - and get something like this: [000h 000 4] Signature : "FACP" /* Fixed ACPI Description Table */ [004h 004 4] Table Length : 000000F4 [008h 008 1] Revision : 04 [009h 009 1] Checksum : 1F [00Ah 010 6] Oem ID : "HP " [010h 016 8] Oem Table ID : "0944 " [018h 024 4] Oem Revision : 00000003 [01Ch 028 4] Asl Compiler ID : "HP " [020h 032 4] Asl Compiler Revision : 00000001 <snip> [038h 056 4] PM1A Event Block Address : 00008000 [03Ch 060 4] PM1B Event Block Address : 00008104 [040h 064 4] PM1A Control Block Address : 00008004 [044h 068 4] PM1B Control Block Address : 00000000 [048h 072 4] PM2 Control Block Address : 00008800 <---- NOTICE 1 [04Ch 076 4] PM Timer Block Address : 00008008 [050h 080 4] GPE0 Block Address : 00008020 [054h 084 4] GPE1 Block Address : 00000000 [058h 088 1] PM1 Event Block Length : 04 [059h 089 1] PM1 Control Block Length : 02 [05Ah 090 1] PM2 Control Block Length : 01 <snip> [0BCh 188 8] Address : 0000000000000000 [0C4h 196 12] PM2 Control Block : <Generic Address Structure> [0C4h 196 1] Space ID : 01 (SystemIO) [0C5h 197 1] Bit Width : 08 [0C6h 198 1] Bit Offset : 00 [0C7h 199 1] Access Width : 00 [0C8h 200 8] Address : 0000000000008100 <--- NOTICE 2 <snip> ACPI Error (tbfadt-0661): 32/64X address mismatch in Pm2ControlBlock: 00008800/0000000000008100, using 64X [20090123] Raw Table Data 0000: 46 41 43 50 F4 00 00 00 04 1F 48 50 20 20 20 20 FACP......HP 0010: 30 39 34 34 20 20 20 20 03 00 00 00 48 50 20 20 0944 ....HP 0020: 01 00 00 00 80 7D FE 77 A4 84 FC 77 00 02 09 00 .....}.w...w.... 0030: B0 00 00 00 F1 F0 F2 00 00 80 00 00 04 81 00 00 ................ 0040: 04 80 00 00 00 00 00 00 00 88 00 00 08 80 00 00 ................ 0050: 20 80 00 00 00 00 00 00 04 02 01 04 08 00 00 00 ............... 0060: C8 00 D0 07 00 00 00 00 01 03 0D 00 32 03 00 00 ............2... 0070: A5 01 00 00 01 08 00 00 00 00 00 00 00 00 00 00 ................ 0080: 00 00 00 00 80 7D FE 77 00 00 00 00 A4 84 FC 77 .....}.w.......w 0090: 00 00 00 00 01 20 00 00 00 80 00 00 00 00 00 00 ..... .......... 00A0: 01 20 00 00 04 81 00 00 00 00 00 00 01 10 00 00 . .............. 00B0: 04 80 00 00 00 00 00 00 01 10 00 00 00 00 00 00 ................ 00C0: 00 00 00 00 01 08 00 00 00 81 00 00 00 00 00 00 ................ 00D0: 01 20 00 00 08 80 00 00 00 00 00 00 01 40 00 00 . ...........@.. 00E0: 20 80 00 00 00 00 00 00 01 00 00 00 00 00 00 00 ............... 00F0: 00 00 00 00 .... <snip> Are these table entries incorrect ?

Question: - if a wrong address would be used, then all sorts of timer related stuff may be all very wrong, huh ? Any comments ? ( Now, what the heck do ... ) Suggestions ? //ARNE |
