DSDT Patching for Dummies - SnowLeo with 100% vanilla /S/L/E

[bgalakazam]

Silencer, I have this problem and verified it over 2 weeks time.

When I sleep (close lid, or from button), upon wake, CPU is on max performance and temp goes back to 60 C (just as there is no speedstep).

C and P states seem to break after sleep.

Please advise.

Weird. I have been using sleep for some time (not anymore), and it was fine (except for the sound). Can you check what eats CPU after wake? Install iStat (version 2.0 is free, google it up), and check the processes there after wake. It might be that some software you installed is problemtatic.

Silencer, what do I have to change so I get microphone working at the cost of sleep? I want to give it a try since I won't be using sleep that much, but I need Skype

Don't need to sacrifice anything, it works with VoodooHDA before and after sleep, but VoodooHDa has some sound quirks after waking up. Just get one of my latest packs (or someone else's) and use VoodooHDA.kext from there.

Well the issue is still there. I sleep,then on wake, CPU temps go to 65-70 C. stayed like that for 30 min. No process was taking more than 1%. I restarted, and CPU temp dropped instantly to 46-48 C.

Fan spins at the same rate. The temps are high just as they were before I implemented C and P states. Apparently wake doesn't turn them back on again.

P.S. Can you repost your latest Extra? Cheers.

Hi.
I m just wondering have you ever figured out any optimized way to control fan? BTW are you able to get fan and other sensor reading via the new version of Fakesmc?
Thanks for your guild. It definitely educated me!

Well, I've been a bit rusty lately, didn't check any updated kexts, since my setup was working just fine. But I've just quickly tried latest FakeSMC.kext with plugins, and no luck so far. The only additional value I could see in iStat was CPU voltage, which is not very useful. ThinkPad fan is not detected automatically, need to try to mess with DSDT. The same goes for GPU temperature. So I've now returned to the original FakeSMC.kext.

Hi
I m currently using HWSensors. Check it out http://www.insanelymac.com/forum/index. ... pic=234452.
It loads faster, and can be loader in extra. I also found out we use PC83785 SuperIO sensor, But the project only have 8379X. Actually there wont be much difference between them. The Plug-in loaded, but no sensor readings.

Perhaps I am digging up an old, dead, thread. If I am, please forgive me. After using Lavalay's tool, my DSDT among all the other devices ACPI had been dumped in a bin format. I am supposed to rename this to .dsl or .asl, or was there an option to dump to these format's that I had missed? I am currently in my Linux distro making my second SSD bootable for the initial Leo install. Hopefully I am able to answer my own question before I make my self look stupid and if not, well thank you for your help guys. I really appreciate this thread

The thread is not dead, but the answer to your question is in the very first original post. To decode the binary DSDT you will need to use a tool called DSDTSE. The the original post for links and description.

You have a very simple syntax problem somewhere near PNLF device. Upload your DSDT somewhere, I'll have a look.

[Charlie.Brown]

You have a very simple syntax problem somewhere near PNLF device. Upload your DSDT somewhere, I'll have a look.

Because you are being so kind. There are absolutely no differences in our DSDT's except our video cards. Mine has the string 7145 as I am sure you are well aware of. If this is already included in the DSDT provided in the first post I'm going straight to Snow. If not, could you please provide the appropriate DSDT Silencer? Thank you.

Oh and I am posting from my hackintosh right now. I am able to get Leo working 100% but whenever I use AresBLN 1.1.9, it never works.

[Silencer]

In that case you can use one of my DSDTs from the posts above, no need to edit yours.

Well, AsereBLN is the bootloader of choice, it actually makes a lot of things easier and better. Make sure you are able to use it before going forward with further improvements.

[chris-uk]

silencer - i think you're a dsdt genius so i'll ask you before i waste hours trying to find the answer..

i have a t60p with the v5250 - i'm still on 10.5.x and been running it for about 18 months with no real issues - i lost sleep a while ago when i updated, and also seem to have temperature issues but i just run at 1ghz and it's zippy enough and stays cool.

i'm going to make the move to 10.6 following your guide - i haven't had time to fully understand it all yet, but am planning to spend some time on it

something i've been wondering is this - given my graphics card (71D4) is the same as 71DE (this is what i changed in patching my kexts on 10.5) - is it possible in DSDT to 'relabel' the graphics card ID rather than having to patch kexts?

thanks..``

Well, theoretically it should be possible, but there is some hardware where re-labeling doesn't do the trick. GPU is one of that hardware. I've tried with my card to relabel it as X1600, and had no luck. What works though, is modification of a kext *.plist to include your ID.

[Silencer]

For anyone interested, here's the latest copy of my /Extra: http://www.mediafire.com/file/ndeddhr2r ... 1-2011.zip

It is for 10.6.6, and it contains important update for the fan speed control. The fix is in FakeSMC.kext (+plugin) and in DSDT. DSDT contains code for temperature measuring and setting appropriate speed. It is optimized for my CPU - Core2Duo 2.3GHz, so if you have anything seriously different you might want to change some values, but in general it will work fine for everyone, full speed kicks in at about 80 degrees, which is safe more that enough (Core2Duo works fine up to 100 degrees). I might include this patch information in the original post if I ever get around it.

Important thing is that in order to use this patch you need to install iStat Menus 2.0 (3.0 is not free anymore). It is widely available everywhere if you google it. How it works is that iStat menus checks CPU temperature every few seconds depending on your settings. And it does so by invoking a method in your DSDT. This method in turn has the code that sets the fan speed depending on the current temperature. I've thoroughly tested it with CPUTest, running it for hours at full load, and this new fan fix worked way better than it was before, when the fan speed was always the same - too loud at no load, too weak with full load.

More info about this fix is available in the following thread: http://forum.thinkpads.com/viewtopic.php?f=32&t=91141

[Anastasius]

WOW! Very cool!
Seems to work absolutely OK on my X61t 7767. Thank you for the great work!
(I tried it with your DSDT - but some hardware parts on my tablet stopped working - like Tablet. Need to incorporate your changes into my DSDT).

And is there a way to turn fan completely off when having CPU temperature around 60C, for example? As it is with TpFanControl on Windows?

[Silencer]

And is there a way to turn fan completely off when having CPU temperature around 60C, for example? As it is with TpFanControl on Windows?

Sure, it's actually set up now to switch off at 55 degrees and switch on at 60. But this can be easily adjusted, it's just you don't want to have the same threshold, otherwise fan will start and stop almost constantly.

[grandflash]

It is working on my x61t too. I have a question regarding to screen rotation with gma 965 aka x3100. I was looking for a tool rotating the screen like in windows 7 a long time ago. 2 months ago I found it http://dev.xiligroup.com/?p=1571. Can someone test it to, please? In my case, the mouse cursor is not flipped 180° too, that is really bad. Maybe it is related to the tablet driver or ps2?

Sorry for noob question, where do I modify this value? Thank you!!!

As an offtopic, I'm using SwitchResX - the whole picture gets flipped or rotated 90,180,270 with a click of a button. I also modified TabletMagic driver to flip the tablet portion as well.

[Silencer]

In DSDT. Check the original thread regarding fan speed control I've linked above, there's the code example that explains how to do it.

Silencer, may you help me to flip the tablet portion? How do you enable this feature. Thanks for your help in advance.

I do know SwitchResX too, but did not know that it can rotate the whole screen. Wow.

has published a bios for T61, T61p, R61/R61i X61, X61s X61s SXGA+ X61 Tablet X300 to enable SATA II Speed on your laptop. I have a Intel Postville built in which had only 130 MB/s and now rocks with 250 MB/s (sequential read). By the way, the bios disables the Lenovo hardware check (white list). Have fun.

In my DSDT (X61tablet) i fixed a lot of devices like IntelHDA1984 (Sound), IntelGMAx3100(Video), Serialport for Tablet and WiFi of course. I had a legacy kext in E/E doing this prior. If your interested:

http://osx86.co/f57/installing-snow-leo ... 50669.html

He provided a patched AppleHDA.kext too (X61tablet with AD1984) in the linked post above.

I would help if I had a tablet. Never had any experience with them. I think Sebinouse should be able to help you better, check out this thread.

This is quite interesting. I've spent quite some time working out how to make AppleHDA work, and almost succeeded, but on T60/T60p/X60 we have 1981HD audio codec, which is rather buggy and it will not work with AppleHDA properly.

[Anastasius]

It's not the word! I can confirm that with the DSDT provided the AppleHDA started working (X61T, 7767, AD1984 sound card)!
All sound devices seems to work fine - including Mic.

Though the tablet portion stopped working - will do the integration of this DSDT into my own one.
Thank you!

Update: Wow, I love you, grandflash and Silencer! I added the HDEF device from the DSDT provided and AppleHDA started working! And it seems the system is working faster than it is with VoodooHDA.

Update2: We have to make some kind of Wiki for all those hacks.

Hi, I was wondering if someone could help me out with my buggy DSDT. I think it probably has just a simple syntax error, but I don't know enough of ACPI to figure it out myself. The following link is a zip file with my original and "fixed" DSDTs, as well as the logs from compiling/attempting to compile both.

Thanks in advance.

@Silencer:
Can you please explain what exactly you are doing by patching the CPU0/CPU1 scopes in DSDT in order to enable speedstep feature.
It seems that you are overwriting the _CST function (= what gets executed when the system wants to enter a cstate?) but i couldn't find your code snippet or anything similar neither in the original MacBook1,1 DSDT/SSDTs nor in my Thinkpad x60ts DSDT/SSDTs. There are no _CST functions or C*M* arrays!

All I could find in my TPs SSDT is the following (which is almost similar to what's in the original MacBook1,1 SSDT!):

Code: Select all

 Scope (\_PR.CPU0)
    {
        Name (HI0, 0x00)
        Name (HC0, 0x00)

        {
            CreateDWordField (Arg0, 0x00, REVS)
            CreateDWordField (Arg0, 0x04, SIZE)
            Store (SizeOf (Arg0), Local0)
            Store (Subtract (Local0, 0x08), Local1)
            CreateField (Arg0, 0x40, Multiply (Local1, 0x08), TEMP)
            Name (STS0, Buffer (0x04)
            {
                0x00, 0x00, 0x00, 0x00
            })
            Concatenate (STS0, TEMP, Local2)
            _OSC (Buffer (0x10)
                {

What are you doing? Just curious

Well, usually you have to not only patch _CST function but also PSS. CST is for C-states and PSS is for P-states, which is actual speedstep. My Thinkpad ACPI already has proper definition of speedstep which works well with OSX. so I only patch CST to enable deep sleep and lower power consumption.

It looks like you didn't extract all SSDT tables, there are a bunch of them.

It looks like you didn't extract all SSDT tables, there are a bunch of them.

I extracted them all via "acpidump -a" and grepped them for "CST" or "C1M1" "C1M2" and so on... so I'm pretty sure. Weird :/
I uploaded them, in case you wanna have a look: http://www.mediafire.com/?vrdf27bchahw395
