[HOWTO] ACPI access for monitoring

48 posts in this topic

Recommended Posts

This is the guide how to make monitoring of hardware parameters (temperatures, fan speeds, voltages etc) using DSDT programming.
The method invented by me with THeKiNG presence and improved by Kozlek.
 
Prerequisites
There is FakeSMC plugin named ACPImonitor in my branch or renamed to ACPISensors in kozlek's branch. They are the same.
HWMonitor or other monitoring application: iStat, K-Stat-i, ...
 
How it works.
HWMonitor or other software make a request for known SMC key, for example TA0P (ambient temperature), every 1 seconds.
The request catched by FakeSMC which knows that the key registered by ACPImonitor plugin.
This plugin knows that the value for the key must be read from ACPI device "monitor" by method "TCRR" and make a request to AppleACPIPlatform for evaluate this method.
AppleACPIPlatform interpretates AML codes written into DSDT, finds the method and calculates the value using hardware access.
The value return back to ACPImonitor -> FakeSMC -> AppleSMC -> HWMonitor which shows the "temperature".
 
The kext ACPImonitor will not work OOB. It will work only with DSDT patches for the usage.
 
Simple example DSDT.

                Device (FSAM)
                {
                    Name (_HID, EisaId ("APP0111"))
                    Name (_CID, "monitor")
                    Name (TCRK, Zero)
                    Method (TCRR, 0, NotSerialized)
                    {
                        Return (TCRK)
                    }

                    Method (TCRW, 1, NotSerialized)
                    {
                        Store (Arg0, TCRK)
                        Return (TCRK)
                    }

                    Method (TCPP, 1, NotSerialized)
                    {
                        Store (\_TZ.THM._TMP (), Local0)
                        Return (Local0)
                    }
                }

You have to create new device. It must have
Name (_CID, "monitor")
This is the key for ACPImonitor attached to it.
Then see Method (TCRR,0, NotSerialized) mentioned above. It will return a value or variable TCRK.
In this demo I made a method TCRW which will fill the variable TCRK from SMC key.
The I have to make correspondence ACPI_methodSMC_key in ACPImonitor.kext/info.plist

I can write values to the SMC key TA1P
./SMC_util3 -kTA1P -w28
and see the value 28 appears in HWMonitor as "Ambient temperature" ;)
Value conversions must be provided in DSDT.
 
Predefined keys
ACPI        SMC     Name
TCPU        Th0H    CPU heatsink
TSYS        TN0P    Northbridge temperature
TDIM        Tm0P    DIMM temperature
TAMB        TA0P    Ambient
TCPP        TC0P    CPU proximity
VCPU        VC0C    CPU voltage
VMEM        VM0R    DIMM voltage
ACDC        ACIN, ACEN  Presence of AC power
FAN0 - FAN9 for FAN speed
FTN0 -FTN9 for FAN rotation time
 
In the case of FAN reading we also want to assign name to them. It is also possible with the Info.plist

What to monitor in real DSDT?
This is individual. So why the ACPImonitor will not work OOB.
See example from my notebook. looking through DSDT I found the follow region.

                    OperationRegion (TMIF, SystemMemory, 0xFF800160, 0x20)
                    Field (TMIF, ByteAcc, Lock, Preserve)
                    {
                        THS0,   8, 
                        THS1,   8, 
                        THS2,   8, 
                        Offset (0x08), 
                        FAN1,   8, 
                        Offset (0x10), 
                        TSP0,   8, 
                        TSC0,   8, 
                        TSP1,   8, 
                        TSC1,   8
                    }

Looks like three temperatures and one FAN.
 
As well I found ThermalZone

    Scope (_TZ)
    {
        ThermalZone (THM)
        {
            Method (_CRT, 0, NotSerialized)
            {
                Store (\_SB.PCI0.LPCB.WSEC.C2K (\_SB.PCI0.LPCB.WSEC.TSC0), Local0)
                Return (Local0)
            }

            Method (_TMP, 0, NotSerialized)
            {
                Store (\_SB.PCI0.LPCB.WSEC.C2K (\_SB.PCI0.LPCB.WSEC.THS0), Local0)
                Return (Local0)
            }

 

 
_CRT - critical temperature
_TMP - current temperature
_SB.PCI0.LPCB.WSEC.C2K is a method to convert Celsius to Kelvin degrees.
So I see that the field THS0 is really CPU temperature.
 
Using ACPImonitor is only way to do monitoring on notebooks because no other methods works and because it usually contains ThermalZone.
 
I know my guide is too short and hope some users shows own examples how to do ACPI monitoring.
 
Note. This method is useful mostly for notebook where temperature and FANs control present in DSDT.
For desktops there are plugins like ITE87xx, Winbond, Fintek depending on you LPC chip installed.
 
 
10.10.2017 ACPIMonitor version 1.0.3
There is a possibility to define some types and sizes for custom keys

            <key>keysToAdd</key>
            <dict>
                <key>TCRR</key>
                <string>TA0P-2</string>
                <key>TCRW</key>
                <string>TA1P-3</string>
                <key>MSLD</key>
                <string>MSLD-1</string>
            </dict>

 
The number after key name means follow
0 -> "flag", len 1
1 -> "ui8 ", len 1
2 -> "ui16", len 2
3 -> "sp78", len 2
4 -> "ui32", len 4

May this plugin live with the other plugins?

Yes. Making plugins we checked for compatibility.

Fans will be doubled. So If one plugin uses FAN0 then other plugin take next number FAN1.  And so on.

how to get fan RPM in HWmonitors

Make the Device as in my example.

Provide a method that will call one of your methods.

Write a line into ACPImonitor.kext/info.plist with correspondence of ACPI method and SMC keys.

Install the kext and see into HWMonitor.

@Slice I really have no idea what code is for fan and for temperatures in this laptop. I am only familiar with other devices in my ACPI files.

Could you give me a hand please? What should I do and in what order?

 

ASUS X550LDV dsl files.zip

 

I am wanting to get rid of kozlek's HWSENSORS and my old FakeSMC version and use yours, but I need some help for that.

Thanks :D

            {
                Store (0x05, Local1)
                While (Local1)

                        Decrement (Local1)

                }

                Return (KELV (Local0))
            }

KELV () - is a procedure to convert Celsius to Kelvin. 

But you need Celsius and the method Store (RTMP (), Local0) gives you the value.

 

See about fans

Name (FANS, Zero)
        Method (RFAN, 1, NotSerialized)
        {
            If (\_SB.PCI0.LPCB.EC0.ECAV ())
            {
                Store (\_SB.PCI0.LPCB.EC0.ST83 (Arg0), Local0)
                If (LEqual (Local0, 0xFF))
                {
                    Return (Local0)
                }

                Store (\_SB.PCI0.LPCB.EC0.TACH (Arg0), Local0)
                Divide (Local0, 0x64, Local1, Local0)
                Add (Local0, One, Local0)
                If (LLessEqual (Local0, 0x3C))
                {
                    Store (Local0, FANS)
                }
                Else
                {
                    Store (FANS, Local0)
                }
            }
            Else
            {
                Store (Zero, Local0)
            }

            Return (Local0)
        }

You can use the method RFAN to get a speed of it. I don't know what is the value so you should make observations what value will be shown by HWmonitor and then created additional recalculation to see rpm.

                    {
                        Decrement (Local1)
                    }
                    Else
                    {
                        Store (Zero, Local1)
                    }
                }

                Return (KELV (Local0))
            }

KELV () - is a procedure to convert Celsius to Kelvin. 

But you need Celsius and the method Store (RTMP (), Local0) gives you the value.

 

See about fans

Name (FANS, Zero)
        Method (RFAN, 1, NotSerialized)

            {
                Store (\_SB.PCI0.LPCB.EC0.ST83 (Arg0), Local0)
                If (LEqual (Local0, 0xFF))
                {
                    Return (Local0)
                }

                Store (\_SB.PCI0.LPCB.EC0.TACH (Arg0), Local0)
                Divide (Local0, 0x64, Local1, Local0)
                Add (Local0, One, Local0)
                If (LLessEqual (Local0, 0x3C))
                {
                    Store (Local0, FANS)
                }
                Else
                {
                    Store (FANS, Local0)
                }
            }
            Else
            {
                Store (Zero, Local0)
            }

            Return (Local0)
        }

You can use the method RFAN to get a speed of it. I don't know what is the value so you should make observations what value will be shown by HWmonitor and then created additional recalculation to see rpm.

 

HOW SHOULD I PROCEED TO USE THE METHOD RTMP THEN??

ALSO, AS YOU CAN SEE IN THIS FOLLOWING IMAGE, HWSENSORS DOESNT SHOW ANY FANS.

The plugin is not intended to work OOB.

You must be a programmer to write an monitoring method in your DSDT.

                Device (FSAM)
                {
                    Name (_HID, EisaId ("APP0111"))
                    Name (_CID, "monitor")
                    Method (FAN0, 0, NotSerialized)
                    {
                        Return (\_SB.TZ.RFAN())
                    }

Then with this device FSAM, can I use it to show the rpm of the fan in HWMonitor of kozlek and maybe modify FakeSMC?

If so, how can I do it?

Yes, kozlek's FakeSMC+kozlek's ACPISensors+kozlek's HWMonitor + this DSDT

Don't mix different thing.

But I am not sure that kozlek was not change something again and the method will not work occasionally.

i run sierra on w520...but hW can't show system fan....so i watch this DSDT edit  gothic860 who run also w520 provide

Slice. Sorry to bother you again

I used a monitoring program for sensors and frequencies in Windows, and I saved the sensor information from the hardware.
It is in this document:
 
 
In this document, inform the voltages and clocks of my GPU (Radeon HD7850), can that with this information, can be inserted in the kexts of sensor plugins?
 
Thanks for your attention

It is not enough. You must write methods to get values found in your DSDT.

"anywhere" - yes, probably inside Device (LPCB)

They absent until you will write procedures to support this.

This is a table of names that known to ACPImonitor plugin that should be used by a programmer to write own monitoring method.

Hmmm got it!

 

Can you help me to do that? I'm not ACPI expert...

Great work and thank you for putting this together.

 

I am trying to get access to values in my sensor hub on my MS Surface Pro 3.  I would also like to enable the volume rocker, power button and windows home button on the digitizer.  The sensor hub is on i2c and I have it enumerated but I believe there is more to it as I've not been able to pull any value data out of it aside from looking at the properties.

 

Id started  to look into enabling the buttons and apparently they are handled via monitoring the gpio and sending acpi events.  I've enabled the Rehabman's ACPI debug kext and made the needed dsdt changes but don't see any acpi events being generated.  Apparently based on some linux driver support the buttons use a non-standard pin config for the gpio.  

 

Would any of this fit into the acpi sensors detection hwsensors uses and if possible, monitoring the rotation/axis/accelerometer and other sensors thru this though, I am not sure what their sam acpi value equivalent would be.  

 

I was able to verify the lid sensor for the typecover is infact working as it follows the acpi spec.  I did also discover a type of tilt sensor built into the typecover that can detect rotation and built a discovery app that uses iokit to output the values.  

 

https://bugzilla.kernel.org/show_bug.cgi?id=84651

 

Any help is appreciated.

 

Thanks!

But the purpose of the project is monitoring temperature and fans speed as it does real mac by SMC controller.

Are there SMC keys on real Macs corresponding to rotation/axis/accelerometer?

Or it should be other drivers like mouse/keyboard/HID system?

      Esse post tem o propósito de documentar os patches necessários para a utilização da kext VoodooI2C e seu satélite VoodooI2CHID no notebook Acer Aspire F15 (ACER-F5-573G).
       
      VoodooI2C é um projeto que adiciona suporte para dispositivos que utilizam o barramento I2C. O trackpad ELAN0501 do notebook Acer Aspire F15 utiliza esse barramento internamente.
       
      As outras opções para ativar o trackpad neste notebook envolvem usar o VoodooPS2Controller ou o ApplePS2SmartTouchPad. O problema do primeiro é que... bem, ele não funciona. No momento em que o trackpad é tocado, o cursor pula pela tela toda sem parar. Já o segundo é o mais fácil pois funciona bem e é capaz de prover funções de multitoque e gestos. Porém, eu sempre achei alguns gestos do ApplePS2SmartTouchPad meio esquisitos, como a rolagem que não acompanha o toque precisamente como aconteceria em trackpads Synaptics no macOS.
       
      Então descobri que era possível usar o VoodooI2C com trackpads ELAN e resolvi tentar. Ao contrário do ApplePS2SmartTouchPad, o VoodooI2C necessita de muita configuração prévia, sendo o mais complicado o processo de GPIO pinning, mas fiquei bastante feliz com os resultados. Esse post documenta os patches usados.
       
      Meu hackintosh é baseado na EFI de johnnywolinger para macOS 10.14. Não o conheço, mas já deixo meus agradecimentos por ter facilitado minha vida. Como estou rodando o Catalina 10.15.5, tive que atualizar algumas kexts (WhateverGreen se não me engano) para evitar um KP durante o boot. A DSDT que eu estou utilizando veio do repositório dele. As únicas alterações que fiz foram os patches necessários ao VoodooI2C.
       
      PASSOS
      1. Baixe o MaciASL neste link.
      2. Abra a sua DSDT nele e aplique os patches [GPIO] GPIO Controller Enable [SKL+] e [Windows] Windows 10 Patch, conforme foto no spoiler. O propósito desses patches é explicado em detalhes no guia de instalação do VoodooI2C. Simplificando, o primeiro patch ativa os interrupts e o segundo permite que o macOS enxergue o dispositivo I2C.
      3. A partir disso, é necessário aplicar os patches específicos de cada computador. No spoiler, eu explico o processo que usei para encontrar as informações. O texto só faz sentido se você já leu o guia de instalação original. Caso não esteja interessado nos detalhes, siga em frente.
      4. Na DSDT, encontre o method _CRS, que está no final do dispositivo TPDE.
      5. Encontrado o Method _CRS, copie o código abaixo.
      Name (SBFG, ResourceTemplate () { GpioInt (Level, ActiveLow, ExclusiveAndWake, PullDefault, 0x0000, "\\_SB.PCI0.GPI0", 0x00, ResourceConsumer, , ) { // Pin list 0x003A } }) Method (_CRS, 0, Serialized) // _CRS: Current Resource Settings { Name (SBFB, ResourceTemplate () { I2cSerialBusV2 (0x0015, ControllerInitiated, 0x00061A80, AddressingMode7Bit, "\\_SB.PCI0.I2C0", 0x00, ResourceConsumer, , Exclusive, ) }) Return (ConcatenateResTemplate (SBFB, SBFG)) } 6. Copiado, volte ao MaciASL e selecione todo o Method _CRS, conforme a foto. Selecione desde o "Method (_CRS" até aquela última chave que está no mesmo nível de Method.

       
      7. Cole, substituindo todo o Method. Deverá ficar assim depois de colado. Note que temos um item chamado Name SBFG e um chamado Method _CRS.

       
      8. Se estiver tudo certo, compile a DSDT e coloque na pasta EFI/ACPI/Patched, onde o Clover está instalado.
       
      Pra finalizar, basta instalar as kexts VoodooI2C e VoodooI2CHID na pasta de kexts do Clover. Ambas podem ser baixadas aqui.
      Se tudo der certo, ao reiniciar, o trackpad deverá estar funcionando corretamente.

      CONSIDERAÇÕES FINAIS
      Se isso parece difícil demais, não esquenta. A VoodooI2C nem é tão melhor que a ApplePS2SmartTouchPad assim. Fiz mais por curiosidade do que por necessidade.
      Se você quiser BAIXAR A DSDT PRONTA, acesse o repositório do johnnywolinger. Tem tudo lá.
      Por que usar VoodooI2CHID em vez de VoodooI2CELAN? Basicamente, a segunda não funciona. Eu testei tanto com o pin 0x3A quanto com o pin 0x9A. Aparentemente, ela só funciona com dispositivos ELAN mais antigos.
      Por fim, quero transformar esse patch num patch automático a ser utilizado no MaciASL, só que não sei como faz. Se eu aprender, edito o post.
