I couldn't get it to compile out of the box on MacOS Mojave and try on a VirtualBox Ubuntu 18 with CMake. Please make a MacOSX binary available on mdsattacks.com I will chase these CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: X11_Xft_INCLUDE_PATH (ADVANCED) used as include directory in directory /home/ecommerce/Downloads/ridl-master used as include directory in directory /home/ecommerce/Downloads/ridl-master used as include directory in directory /home/ecommerce/Downloads/ridl-master X11_Xft_LIB (ADVANCED) linked by target "mdstool" in directory /home/ecommerce/Downloads/ridl-master X11_Xrender_INCLUDE_PATH (ADVANCED) used as include directory in directory /home/ecommerce/Downloads/ridl-master used as include directory in directory /home/ecommerce/Downloads/ridl-master used as include directory in directory /home/ecommerce/Downloads/ridl-master X11_Xrender_LIB (ADVANCED) linked by target "mdstool" in directory /home/ecommerce/Downloads/ridl-master

Seems today's Ubuntu 18 kernel update on VBox crashes my iMac Pro with hyperthreading turned off. I hope it's one time only, first time this machine crashed in almost 18 months.

I will try to work on the Mac OS X port in the next few days, to give you an idea of what has to be changed:

deepdad commented 5 years ago

if it relies on cpuid, will it be correct when you turn off hyper-threading like Apple advises? why doesn't it do an actual test like described in your paper?

StephanvanSchaik commented 5 years ago

Not all information comes from cpuid, such as whether your CPU has SMT enabled or disabled. This is why the tool tries to query this information from known APIs that the OS provides.

The tool doesn't use any of our tests because: 1) Intel hasn't given us the green light yet for this. 2) Mac OS X lacks an API to set explicit processor affinity to actually run the tests using SMT.

508d549341d785afc59681ed3f219ef72437d637 adds support for Mac OS X.
