Hallo,

ich habe mich jetzt durch die verschiedenen Quellen gewühlt und dabei viele interessante Erfahrungen gewonnen. Z.B. weiß ich jetzt, dass in den unterschiedlichen Versionen der nvapi.h unterschiedliche Funktionsdefinitionen zu finden sind, und dass Funktionen, die man in den neueren Versionen nicht mehr findet, durchaus noch zu funktionieren scheinen.

Meine Testerei wird leider dadurch eingeschränkt, dass ich für den Anschluss an meinem Notebook, an dem mein Display hängt, den NVIDIA-Treiber nicht aktivieren kann. So laufen einige Funktionen auf den Fehler -6. Aber einige Funktionen laufen klaglos.

Code: Select all

            NvAPI._GPU_GetMemoryInfo                         := DllCall(NvAPI.DllFile "\nvapi_QueryInterface", "UInt", 0x774AA982, "CDECL")
stimmt leider nicht. 0x774AA982 ist die ID der Funktion GetDisplayDriverMemoryInfo, wie es auch unten im Skript steht. Es sollte also

Code: Select all

            NvAPI._GetDisplayDriverMemoryInfo                := DllCall(NvAPI.DllFile "\nvapi_QueryInterface", "UInt", 0x774AA982, "CDECL")
sein. Wo hast Du diese lange Liste mit ID's gefunden? Ich konnte so etwas im Netz nicht finden.

Lange Rede, kurzer Sinn, ich habe hier ein paar Funktionen, die zu laufen scheinen. EnumNvidiaDisplayHandle bringt bei mir leider den o.a. Status -6.

Code: Select all

Hey just me
Danke für deine Bemühungen bisher

Gefunden hab ich die ID's hier ==> How to get the id (memory address) of dll-function?
Mich würde aber interessieren wie er auf die ID's dann gekommen (bzw analysiert hat) ist weil mein output für die nvapi.lib via dumpbin sieht so aus (output.7z)
Der Output ist von 2013 deswegen haben sich bestimmt auch ein paar Namen geändert.

In der letzten Version (r343) gibt es GetDisplayDriverMemoryInfo nicht mehr, deswegen denke ich, dass das jetzt GPU_GetMemoryInfo und die Adresse die gleiche geblieben ist.

Hallo jNizM,

nach der aktuellen Doku braucht GPU_GetMemoryInfo() ein physisches Handle auf eine GPU, während GetDisplayDriverMemoryInfo() ein Displayhandle erwartet (worin auch immer sich die unterscheiden).

Ich werde mir auch den Link mal anschauen, für 64-Bit taugen die ID's aber anscheinend nicht.

Re: Projekt NVIDIA

Denk mal die ID's für 64-Bit unterscheiden sich weil es auch 2 nvapi.lib Dateien gibt

32-Bit: nvapi-r343\x86\nvapi.lib (582 KB)
64-Bit: nvapi-r343\amd64\nvapi64.lib (699 KB)

Hiermit hab ich zumindest ein Output bekommen:

Ja, das klappt, aber nur, weil 0 das DEFAULT_DISPLAY_HANDLE ist. Wenn Du, wie im Funktionskopf beschrieben, ein gültiges hPhysicalGpu Handle übergibst, gibt es einen Fehlerstatus.

Re: Projekt NVIDIA

07 Nov 2014, 02:54

Mann, ich hasse das. Da verteilt NVIDIA eine DLL, die eigentlich keine ist, weil sie fast keine Funktionen exportiert und mit Hilfe der LIB Datei statisch gelinkt werden soll. Und dann gibt es auch noch zwei Versionen des API, ein unvollständiges für's gemeine Volk und dann noch ein wahrscheinlich vollständigeres für Entwickler, die sich den Mund verbieten lassen müssen, damit sie es bekommen. So findet man mal hier mal da die in der öffentlich verfügbaren Dokumentation beschriebenen Funktionen in einer nvapi.h, oder auch nicht. Und die im Netz verfügbaren bzw. von jNizM gefundenen ID-Sammlungen sind alle nicht besonders aktuell, so dass man nicht sicher sein kann, ob sie überhaupt zu den aktuellen DLL-Versionen passen. Zusammen mit der nicht wirklich aktiven NVIDIA-Grafik in meinem System führt das zu einer wachsenden Demotivation.

Ich habe mich trotzdem an der (nicht dokumentierten) Funktion GPU_GetUsages() versucht, bekomme hier aber bestenfalls den vielsagenden Status -1 // Generic error. Schau doch mal, ob Du ein besseres/anderes Ergebnis bekommst:

Code: Select all

   /*
   ///////////////////////////////////////////////////////////////////////////////

   GPU_GetUsages(PhysGpuHandle := 0) {
      Static MAX_USAGES_PER_GPU := 33
      Static SizeOfUsages := 4 + (MAX_USAGES_PER_GPU * 4)
      If (PhysGpuHandle = 0)
         PhysGpuHandle := This.EnumPhysicalGPUs().1
      VarSetCapacity(Usages, SizeOfUsages, 0)
      NumPut(SizeOfUsages|0x10000, Usages, 0, "UInt")
      If (NvStatus := DllCall(NvAPI._GPU_GetUsages, "Int", PhysGpuHandle, "Ptr", &Usages, "CDECL")) = 0

Ja, seit ziemlich genau 5 Minuten (zumindest für 32-Bit):

Man muss die Datei nvapi.lib mit der dumpbin.exe disassemblieren (so man das darf):

Code: Select all

dumpbin.exe /DISASM /OUT:Pfad_einer\Ausgabedatei Pfad_zur\nvapi.lib
In der Ausgabedatei finden sich dann Abschnitte mit Namen wie:

Code: Select all

_NvAPI_GPU_GetMemoryInfo:
und ja, das sind die Funktionsnamen.

Im folgenden Codeabschnitt findet sich dann nach meinen Stichproben immer folgende Befehlskombination:

Code: Select all

 00001164: 68 68 B3 F9 07     push        7F9B368h
 00001169: FF 15 00 00 00 00  call        dword ptr [[email protected]@[email protected]]
Und was da gepushed wird, sieht für viele Funktionen recht bekannt aus.

Hut ab just me =)

NvAPI IDs - Aktuelle (r343) + Alte
_NvAPI_IDs.txt

NvAPI Status
_NvAPI_Status.txt

Class_NVIDIA (ist natürlich noch nicht vollständig und fertig)
Class_NVIDIA.ahk


und GetMemoryInfo() funktioniert auch

Code: Select all

GetMemoryInfo(Index := 1)
{
	static NV_DISPLAY_DRIVER_MEMORY_INFO := 24
	hPhysicalGpu := this.EnumPhysicalGPUs()[Index]
	VarSetCapacity(pMemoryInfo, NV_DISPLAY_DRIVER_MEMORY_INFO, 0), NumPut(NV_DISPLAY_DRIVER_MEMORY_INFO|0x20000, pMemoryInfo, 0, "UInt")
	if !(NvStatus := DllCall(NvAPI._GPU_GetMemoryInfo, "Int", hPhysicalGpu, "Ptr", &pMemoryInfo, "CDECL"))
	{
		MI := {}
		MI.Dedicated        := NumGet(pMemoryInfo,  4, "UInt")
		MI.Available        := NumGet(pMemoryInfo,  8, "UInt")
		MI.System           := NumGet(pMemoryInfo, 12, "UInt")
		MI.Shared           := NumGet(pMemoryInfo, 16, "UInt")
		MI.CurrentAvailable := NumGet(pMemoryInfo, 20, "UInt")
		return MI
	}
	return "*" NvStatus
}

und hier entsteht dann ein GUI-Beispiel:

Hallo jNizM,

ich habe mich mal an der Funktion GPU_GetDynamicPstatesInfoEx() versucht, bekomme aber hier wieder nur den Status -1.Vielleicht hast Du mehr Erfolg.

Wie ich es sehe, signalisiert die Funktion im zweiten Feld der Rückgabestruktur im Bit 0, ob die dynamic pstates überhaupt aktiviert sind. Wenn ja, sollten in den folgenden Feldern die Werte für die vier 'Domänen' folgen, wobei es wieder ein Bit gibt, das eine Aussage über die Existenz dieser Domäne enthält.

Code: Select all

   /*
   ///////////////////////////////////////////////////////////////////////////////
   //
   // FUNCTION NAME: NvAPI_GPU_GetDynamicPstatesInfoEx
   //
   //! DESCRIPTION:   This API retrieves the NV_GPU_DYNAMIC_PSTATES_INFO_EX structure for the specified physical GPU.
   //!                Each domain's info is indexed in the array.  For example:
   //!                - pDynamicPstatesInfo->utilization[NVAPI_GPU_UTILIZATION_DOMAIN_GPU] holds the info for the GPU domain. \p
   //!                There are currently 4 domains for which GPU utilization and dynamic P-State thresholds can be retrieved:

Hallo,

NvAPI_SYS_GetDriverAndBranchVersion() funktioniert bei mir ausnahmsweise, allerdings mit folgender Änderung:

if !(NvStatus := DllCall(NvAPI._SYS_GetDriverAndBranchVersion, "UIntP", pDriverVersion, "Ptr", &szBuildBranchString, "CDECL"))

Grund: NvAPI_SYS_GetDriverAndBranchVersion(NvU32* pDriverVersion, NvAPI_ShortString szBuildBranchString)

Was so ein kleines "P" so alles anstellt :D
Danke für den Tip

Mich wunderts nur das bei mir angezeigt wird:
Version: 34475
Branch: r343_00

Und ein anderes Tool was ich zum Überprüfen benutze zeigt:
Version: R344.75
Branch: r343_00-311



GPU_GetDynamicPstatesInfoEx() & GPU_GetUsages() schau ich mir gleich mal an

Na ja, das R344.75 dürfte einfach nur aufbereitet sein. Es wäre jedenfalls merkwürdig, wenn in einem 32-bittigen UINT Feld solche Zeichen zu finden wären.

Wo das angehängte -311 herkommt, weiß ich auch nicht. Vielleicht nutzt das Tool noch eine weitere/andere Funktion.

Wie fragst du GPU_GetDynamicPstatesInfoEx() ab? bei mir kommt immer ein leeres Feld

Bei GPU_GetDynamicPstatesInfoEx().Enabled ==> 0

Alles, was ich darüber weiß, kommt aus der 'großen' nvapi.h Datei:

Code: Select all

   typedef struct
   {
       NvU32       version;        //!< Structure version
       NvU32       flags;          //!< bit 0 indicates if the dynamic Pstate is enabled or not
       struct
       {
           NvU32   bIsPresent:1;   //!< Set if this utilization domain is present on this GPU
           NvU32   percentage;     //!< Percentage of time where the domain is considered busy in the last 1 second interval
       } utilization[NVAPI_MAX_GPU_UTILIZATIONS];
   } NV_GPU_DYNAMIC_PSTATES_INFO_EX;
Die Felder des Rückgabeobjekts sind:

Code: Select all

Object.Enabled             <- hier landet der Wert aus 'flags'
Object.GPU.IsPresent       <- hier landet der este Wert aus 'bIsPresent'
Object.GPU.Percentage      <- hier landet der erste Wert aus 'percentage'
Object.FB.IsPrecent        <- hier landet der zweite Wert aus 'bIsPresent'
Object.FB.Percentageq      <- hier landet der zweite Wert ...
...
...
Wenn Du allerdings in Enabled 0 geliefert bekommst, weiß ich nicht, ob der Rest überhaupt aussagekräftig ist. Du könntest dann mal Folgendes versuchen:

Pstates.Enabled := NumGet(DynPstInfo, 4, "UInt") ; & 1 auskommentieren

Return to “Ich brauche Hilfe”
