Useful DSDT Edits

Question

This thread is to list the useful DSDT edits that have been posted throughout other topics in this forum and to prevent them from getting lost in multiple pages worth of posts in threads not directly related to that particular edit.

If you have any useful DSDT edits beyond what an ACPI patcher already applies, please post them here.

If you really want to learn then you should go to InsanelyMac and read DSDT fixes for Gigabyte boards and Vanilla speedstepping threads.

I've been reading these threads, and it's quite a lot to digest. Especially hard because new info keeps coming to light, or old assumptions proved false...

Anyway, I've been meaning to start a thread over here with what I could glean from it to see if we can't compile a slightly more intelligible synopsis of what is involved. I've been waiting for a break in my school and work schedule that would allow me a whole weekend to read through those threads in their entirety, but have been just too busy. There's several good reports from those threads, with people getting their temps down into the 30s, so I think this should be a priority. This is the last thing that really separates my Hack from the Mac. So lets's figure it out ElMangoMez...:cool:

Thank you Knotty.... I am glad to help... but this is not my area of expertise... I can barely understand anything in a dsdt... I keep reminding people I am not a real expert, just an good follower of directions.

Thanks! Special!! My board is EP45UD3P. But I had not be able to understand where to insert the Lower temperatures SBRG/LPCB hack in DSDTSE.

Now I could find PX40, added the code, my cpu is running at under 40 degree C! AppleLPC.kext is properly loaded.

61 0 0xffffff7f808f6000 0x3000 0x3000 com.apple.driver.AppleLPC (1.4.9) <9 5 4 3>

Thanks again!

Hmmm wierd. Doesnt seem like I have a c-state table on my system:


ubuntu@ubuntu:~$ cat dmsg_acpi.log | grep -i SSDT
[ 0.000000] ACPI: SSDT dfee8520 003AB (v01 PmRef CpuPm 00003000 INTL 20040311)
[ 1.158737] ACPI: SSDT dfee7f00 0022A (v01 PmRef Cpu0Ist 00003000 INTL 20040311)
[ 1.159000] ACPI: SSDT dfee83c0 00152 (v01 PmRef Cpu1Ist 00003000 INTL 20040311

But they do have a strange entry(0x0 address and REALLY long length) in my CpuPm:


Name (SSDT, Package (0x18)
{
"CPU0IST ",
0xDFEE7F00,
0x0000022A,
"CPU1IST ",
0xDFEE83C0,
0x00000152,
"CPU0CST ",
0x00000000,
0xF000E816,
"CPU1CST ",
0x00000000,
0xF000E816,
"CPU2IST ",
0x00000000,
0xF000E816,
"CPU3IST ",
0x00000000,
0xF000E816,
"CPU2CST ",
0x00000000,
0xF000E816,
"CPU3CST ",
0x00000000,
0xF000E816
})

Any Ideas?
