AppleIntelCPUPWM panics in spite of HPET Fix

R3van · October 12, 2010

Hello,

i`m just playing around with my dsdt and i`m getting confused because i can`t use vanilla AppleIntelCPUPWM.kext without a Disabler, it ends everytime with a panic!

No HPETs available...CPU(s) configured incorrectly ... AppleIntelCPUPowerManagement/

my HPET fix looks like:

	   
			Device (HPET)
			{
				Name (_HID, EisaId ("PNP0103"))
				Name (ATT3, ResourceTemplate ()
				{
					IRQNoFlags ()
						{0}
					IRQNoFlags ()
						{8}
					Memory32Fixed (ReadWrite,
						0xFED00000,		 // Address Base
						0x00000400,		 // Address Length
						)
				})

and it worked under Leopard 10.5.8.

What could that be?

I can try

Upload your dsdt

send me a kextstat also

Thanks, thats very kind

Whats the goal in this?

I have an overclocked cpu up to 4GHz with a little bit raised vcore and working EIST and C1E in Windows.

If i boot in OSX i have the lowered vcore but the full clock rate of 4 GHz, that can`t work in my case.

So i want to try the vanilla speedstep to see if the voltages get managed correctly, maybe with voodoopower in addition.

i fixed the problem with the kernel panic, instead of:

				Device (HPET)
			{
				Name (_HID, EisaId ("PNP0103"))
				Name (ATT3, ResourceTemplate ()
				{
					IRQNoFlags ()
						{0}
					IRQNoFlags ()
						{8}
					Memory32Fixed (ReadWrite,
						0xFED00000,		 // Address Base
						0x00000400,		 // Address Length
						)
				})
				Name (ATT4, ResourceTemplate ()
				{
				})
				Method (_STA, 0, NotSerialized)
				{
					Return (0x0F)
				}

				Method (_CRS, 0, NotSerialized)
				{
					Return (ATT3)
				}
			}

i had this in my dsdt:

				Device (HPET)
			{
				Name (_HID, EisaId ("PNP0103"))
				Name (ATT3, ResourceTemplate ()
				{
					IRQNoFlags ()
						{0}
					IRQNoFlags ()
						{8}
					Memory32Fixed (ReadWrite,
						0xFED00000,		 // Address Base
						0x00000400,		 // Address Length
						)
				})
				Name (ATT4, ResourceTemplate ()
				{
				})
				Method (_STA, 0, NotSerialized)
				{
					If (LGreaterEqual (OSFX, 0x03))
					{
						If (HPTF)
						{
							Return (0x0F)
						}
						Else
						{
							Return (Zero)
						}
					}
					Else
					{
						Return (Zero)
					}
				}

				Method (_CRS, 0, NotSerialized)
				{
					If (LGreaterEqual (OSFX, 0x03))
					{
						If (HPTF)
						{
							Return (ATT3)
						}
						Else
						{
							Return (ATT4)
						}
					}
					Else
					{
						Return (ATT4)
					}
				}
			}

So the problem with AppleIntelCPUPWM seems to be fixed but i have no speedstepping.

With VoodooPowerMini it remains at full frequency and 1.06V idle / 1.10V load

With VodooPowerACPI it remains at full frequency and 1.18V idle / load.

So VoodooPowerACPI doesn`t work with my System at all and VoodooPowerMini changes at least the Voltages (but not enough) but there is no change in cpu-frequencies, how can i get that?

Edit: Without any VoodooPower Kext i get frequency and voltage speedstepping at default settings (FSB 333, Multi 9, Stock Vcore)

with the following settings the pc reboots directly after starting cinebench: FSB 534, Multi 7,5 (4000MHz), VCore raised.

This settings works in Windows so i do something wrong here, what could it be?

-LPC not loaded - Apply

use it(LPC ICH10)

0x18, 0x3A, 0x00, 0x00

-Platformuuid - unnecessary, Chameleon solves this(RC4 or RC5)

-native power managment and restart fix - use Chameleon RC5(delete Null, disabler, voodoopm...)

http://www.insanelymac.com/forum/index.php?showtopic=225766

DOWNLOAD

http://www.insanelymac.com/forum/index.php...st&id=78839

add in boot.plist

<key>GeneratePStates</key>
<string>Yes</string>
<key>GenerateCStates</key>
<string>Yes</string>

avoid using the ESB2

has given many problems

use Kext IOAHCIBLOCK...

Look it

-LPC not loaded - Apply

Done it.

-Platformuuid - unnecessary, Chameleon solves this(RC4 or RC5)

ok

-native power managment and restart fix - use Chameleon RC5(delete Null, disabler, voodoopm...)

Does it include Kabyls latest support for ATI Graphics?

<key>GeneratePStates</key>
<string>Yes</string>

<key>GenerateCStates</key>

<string>Yes</string>

Have it already, but it don`t work with raised vcore, is there a understandable Guide to set P-State and C-State in ssdt?

avoid using the ESB2
has given many problems

use Kext IOAHCIBLOCK..

Will do it

Thanks for help!

I'm not sure

look it, should say something about it

http://forge.voodooprojects.org/

see the version of chameleon

strings /boot | grep Chameleon

Have it already, but it don`t work with raised vcore

Vcore 1.45

http://browse.geekbench.ca/geekbench2/view/294364

my english Sucks

R3van · October 13, 2010

I tried Chameleon RC 5 Build 593 and it didn`t work with my HD 5850 so i stuck at the one provided by Kabyl.

Vcore 1.45

Yes thats fine, but it doesn`t work for me so can you tell me what you had done to get Speedstep with overclocked cpu and raised vcore?

for my speedstep

-AppleLPC loaded

-HPET Fix

-GeneratePStates/GenerateCStates in boot.plist

-------------------

what is your processor?

see values FID, VID...

prepared manually

PStateChanger

Look it

R3van · October 13, 2010

for my speedstep

-AppleLPC loaded

-HPET Fix

-GeneratePStates/GenerateCStates in boot.plist

Done it equal

what is your processor?

My System is in my signature

see values FID, VID...
prepared manually

yes, that is what i`m searching the whole day, i have decompiled my ssdt-Tables but don`t know how to set the correct values for the frequencies and voltages.

This is what i have at standard clocks:

This is what i get overclocked:

What i need is this:

pstate 0 : 4005MHz : 1.240V (real vCore) : FID 7.5 : VID ? : DID ? (7.5 x 534 MHz)

pstate 1 : 3738MHz : 1.200V (real vCore) : FID 7 : VID ? : DID ? (7 x 534 MHz)

pstate 2 : 3471MHz : 1.180V (real vCore) : FID 6.5 : VID ? : DID ? (6.5 x 534 MHz)

pstate 3 : 3204MHz : 1.160V (real vCore) : FID 6 : VID ? : DID ? (6 x 534 MHz)

MaLd0n · October 14, 2010

Look it, your DSDT

I applied the SS

with the values that you provided

change the values in the bios

only

I've read someone talking about it, I think it was mm67

Look at the Scope (_PR)

DSDT_R3VAN_EXAMPLE.aml.zip

R3van · October 14, 2010

so, done with reinstallation.

That did not run so well

i will search for guides how i can patch the ssdt-Tables.

Thanks for help, if you know some threads about it, feel free to post
