CapFrameX OSD with RTSS

It would be interesting for many people. Of course, you would have to make it configurable, so that the impact on performance wouldn't interfere if you didn't want it to.

 

@Unwinder Is there a proper way to get the LUID from the ADL or AGS? In case of a Nvidia card I think it's possible to get it from the NVAPI. I used to notice something like that.

 

Another question. I hope it's ok. ^^

I' m using the following struct to get the fan speed from the ADL.

Code:

  [StructLayout(LayoutKind.Sequential)]
  internal struct ADLFanSpeedValue {
    public int Size;
    public int SpeedType;
    public int FanSpeed;
    public int Flags;
  }

Question: Does the Flags property tells me wether the ZeroFanMode is active or not? The context is overdrive version 7 for a Vega 56 Pulse.

 

Ok, any tips to solve this problem?

Edit: We've "fixed" this problem.

 

You answered me on Twitter a few day ago because of the power entries from the NVAPI. The only entry I can find in the NVAPIWrapper is GetCurrentAbsPower(DWORD dwGpu, DWORD* lpPower) and the relative one as well of course...

I would like to grap all these values. Is that possible?


Edit: Ok, it muste be included in.

NV_GPU_POWER_MONITOR_POWER_CHANNEL_STATUS_V2 channels[NV_GPU_POWER_MONITOR_POWER_CHANNELS_MAX];

 

I've defined the following structs within my C# code.

Code:

[StructLayout(LayoutKind.Sequential, Pack = 8)]
    internal struct NvGpuPowerStatus
    {
        public uint Version;
        public uint ChannelMask;
        public uint TotalGpuPowermW;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 16)]
        public char[] Rsvd;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 32)]
        public NvGpuPowerMonitorPowerChannelStatus[] Channels;
    }

    [StructLayout(LayoutKind.Sequential, Pack = 8)]
    internal struct NvGpuPowerMonitorPowerChannelStatus
    {
        public uint PwrAvgmW;
        public uint PwrMinmW;
        public uint PwrMaxmW;
        public uint CurrmA;
        public uint VoltuV;
        public ulong EnergymJ;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 16)]
        public char[] Rsvd;
    }

And Version

Code:

   public static readonly uint GPU_POWER_MONITOR_STATUS_VER = (uint)
          Marshal.SizeOf(typeof(NvGpuPowerStatus)) | 0x10000;

Delegate with the ID from the RTSS SDK.

Code:

   GetDelegate(0xF40238EF, out NvAPI_GPU_PowerMonitorGetStatus);

It doesn't work. All properties have default values.

 

What is NvU8 actually byte or char?

Edit: It just works. ^^

NvU8 = uint8 = sbyte

And I had to change the pack size to 1.

Code:

 [StructLayout(LayoutKind.Sequential, Pack = 1)]
    internal struct NvGpuPowerMonitorPowerChannelStatus
    {
        public uint PwrAvgmW;
        public uint PwrMinmW;
        public uint PwrMaxmW;
        public uint CurrmA;
        public uint VoltuV;
        public ulong EnergymJ;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = 16)]
        public sbyte[] Rsvd;
    }

 

All these Rsvd arrays only have default values.



Is this normal? And how can I identify the entries? I think names/descriptions would be helpful.

 

Or is it the other way around? You must set identifiers so the parameters can be resolved internally?

Any tips?

 

I get values for all properties except the "Rsvd" arrays.What are these "Rsvd" arrays for?

Code:

[StructLayout(LayoutKind.Sequential, Pack = 8)]
    internal struct NvGpuPowerStatus
    {
        public uint Version;
        public uint ChannelMask;
        public uint TotalGpuPowermW;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = NVAPI.POWER_STATUS_RSVD_SIZE)]
        public byte[] Rsvd;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = NVAPI.POWER_STATUS_CHANNEL_COUNT)]
        public NvGpuPowerMonitorPowerChannelStatus[] Channels;
    }

    [StructLayout(LayoutKind.Sequential, Pack = 1)]
    internal struct NvGpuPowerMonitorPowerChannelStatus
    {
        public uint PwrAvgmW;
        public uint PwrMinmW;
        public uint PwrMaxmW;
        public uint CurrmA;
        public uint VoltuV;
        public ulong EnergymJ;

        [MarshalAs(UnmanagedType.ByValArray, SizeConst = NVAPI.POWER_STATUS_RSVD_SIZE)]
        public byte[] Rsvd;
    }

I've tried byte, sbyte and char as for NvU8. Nothing works.

 

How do you prepare for Zen 3? Will it still be "AMD family 17h processors"?

Edit: No, it's 19h. Linux patch: https://git.kernel.org/pub/scm/linu...t&id=2835d860d3fcc3e4829e96987544e811d35dee48

 

@Unwinder Apparently there is max. amount of lines, that RTSS can display with CX as a non primary client. Is there something we can do from our side? We took most of the code from the Shared Memory example (RTSS SDK) but I cannot find any code which could be responsible for that.
