PCM 2.5.1 - missing CPU model for MacBook Air with i7-4650U?

[Rolf_Andersson]

Hi, I got this error message when trying to run pcm-tsx.x on my MBA (cpu i7-4650U)

Error: unsupported processor. Only Intel(R) processors are supported (Atom(R) and microarchitecture codename Nehalem, Westmere, Sandy Bridge and Ivy Bridge). CPU model number: 69 Brand: "Intel(R) Core(TM) i7-4650U CPU @ 1.70GHz"
Access to Intel(r) Performance Counter Monitor has denied (no MSR or PCI CFG space access).

Adding

"HASWELL_4650 = 69" to the SupportedCPUModels enum in cpucounters.h and

"|| model_ == HASWELL_4650" to isCPUModelSupported in cpucounters.cpp

allowed me to run the program.

Best,

Rolf

Hi Rolf,

thanks for reporting this. We have just recently noticed that and already have a pre-release version supporting this model. Unfortunately your changes above are not sufficient for supporting it correctly in PCM. Let me send you a patch for testing before the official release.

Thanks,

Roman

I will be happy to test the patch.

Rolf,

please try this small patch in the attachment.

Please post the output of

the patch applied cleanly and the make was successful.

Please find the output of ./pmc.x "sleep 1" enclosed
