Below is the output of pcm.

I tried to debug the code, below is the call stack.

libPcmMsr.dylib!MSRAccessor::read(unsigned int, unsigned long long, unsigned long long*) (/Users/bixian/pcm/src/MacMSRDriver/MSRAccessor.cpp:37)

And when the debugger step over kern_return_t ret = IOConnectCallStructMethod(connect, kReadMSR, &idatas, struct_size, &odatas, &struct_size);, the returned value is 268435459 rather than 0.
Below is the code snippet and corresponding arguments passed into IOConnectCallStructMethod

int32_t MSRAccessor::read(uint32_t core_num, uint64_t msr_num, uint64_t * value)
{
    pcm_msr_data_t idatas, odatas;

    size_t struct_size = sizeof(pcm_msr_data_t);
    idatas.msr_num = (uint32_t)msr_num;
    idatas.cpu_num = core_num;

    kern_return_t ret = IOConnectCallStructMethod(connect, kReadMSR,
                                                  &idatas, struct_size,
                                                  &odatas, &struct_size);

    if(ret == KERN_SUCCESS)
    {
        *value = odatas.value;
        return sizeof(uint64_t);
    } else {
        return -1;
    }
}
idatas={
    value=0;
    cpu_num=0;
    mar_num=914;
}
struct_size=16
connect=0
kReadMSR=2

I did some research about IOConnectCallStructMethod. It seems IOConnectCallStructMethod is trying to send a struct to a kext and get the output struct, correct? And I double checked that SIP is disabled and com.intel.driver.PcmMsr is loaded.

I cannot diagnose anymore.

could you run pcm with the -r option?

pcm -r

Does it work?

I don't think -r option makes any difference.

this seems to the the same issue: #608 (comment)

Did you try the manual install procedure: https://github.com/intel/pcm/blob/master/doc/MAC_HOWTO.txt
Could you share the output of kextstat ?

this seems to the the same issue: #608 (comment)

Did you try the manual install procedure: https://github.com/intel/pcm/blob/master/doc/MAC_HOWTO.txt Could you share the output of kextstat ?

I basically follow the instructions in https://github.com/intel/pcm/blob/master/doc/MAC_HOWTO.txt, except I use several cmake options, "-DPCM_NO_ASAN=1", "-DNO_SSL=1", "-DCMAKE_BUILD_TYPE=Debug".

The reason why I use "-DPCM_NO_ASAN=1" is the kext fails to be loaded without this option and give me a error message could not find a kext which exports this symbol ___asan_unregister_image_globals.

The reason why I use "-DNO_SSL=1" is I have no openssl installed.

The reason for Debug cmake type is I want to do some debugging.

Here's part of the output of kextstat. Do you need a full version?

I tried to debug the code, below is the call stack.

And when the debugger step over kern_return_t ret = IOConnectCallStructMethod(connect, kReadMSR, &idatas, struct_size, &odatas, &struct_size);, the returned value is 268435459 rather than 0. Below is the code snippet and corresponding arguments passed into IOConnectCallStructMethod

int32_t MSRAccessor::read(uint32_t core_num, uint64_t msr_num, uint64_t * value)
{
    pcm_msr_data_t idatas, odatas;

    size_t struct_size = sizeof(pcm_msr_data_t);
    idatas.msr_num = (uint32_t)msr_num;
    idatas.cpu_num = core_num;

    kern_return_t ret = IOConnectCallStructMethod(connect, kReadMSR,
                                                  &idatas, struct_size,
                                                  &odatas, &struct_size);

    if(ret == KERN_SUCCESS)
    {
        *value = odatas.value;
        return sizeof(uint64_t);
    } else {
        return -1;
    }
}
idatas={
    value=0;
    cpu_num=0;
    mar_num=914;
}
struct_size=16
connect=0
kReadMSR=2

I did some research about IOConnectCallStructMethod. It seems IOConnectCallStructMethod is trying to send a struct to a kext and get the output struct, correct? And I double checked that SIP is disabled and com.intel.driver.PcmMsr is loaded.

I cannot diagnose anymore.

It fails already here (from your log):

IOServiceOpen returned 0xe00002c7
Unable to build CPU topology

pcm/src/MacMSRDriver/MSRAccessor.cpp

Line 139 in c761ba7

cerr << "IOServiceOpen returned 0x" << hex << setw(8) << kernResult << dec << endl;

Code 0xE00002C7 means kIOReturnUnsupported

Not sure why it is not supported. In PCM we don't use kIOReturnUnsupported at all.

Could you try this from the howto:

Logging/Debugging

Sometimes you will get errors while running utilities that may come from the kernel, and you can use something like this DTrace script to correlate it with user-land behavior:

sudo dtrace -n 'fbt:mach_kernel:_ZN*IOUser*:return /execname == "pcm"/ { @hgram[probefunc, arg1, ustack(20)] = count(); }' -c ./pcm

Various commands that can help diagnose errors:

kmutil log stream
kmutil inspect -b com.intel.driver.PcmMsr

It seems that I finally got pcm working. I disable SIP totally instead of disabling partially(only disabling Kext Signing and Filesystem Protections) and run pcm with option -r(sudo pcm -r). I believe that the terminal printing below is the output we expected. Correct?

For now, my only question is, according to your opinion, which of SIP items are required to make pcm works? You may just provide some suggestions or give me some hints and I will keep trying and testing.

  1. Apple Internal
  2. Kext Signing
  3. Filesystem Protections
  4. Debugging Restrictions
  5. DTrace Restrictions
  6. NVRAM Protections
  7. BaseSystem Verification

yes, this is expected output. Unfortunately I don't have access to MacOS system right now. Your help is much appreciated
