In computing, Machine Check Architecture (MCA) is an Intel and AMD mechanism in which the CPU reports hardware errors to the operating system.. Intel's P6 and Pentium 4 family processors, AMD's K7 and K8 family processors, as well as the Itanium architecture implement a machine check architecture that provides a mechanism for detecting and reporting hardware (machine) errors, such as: system ...

They both provide CPU cache information in a series of sub-leaves selected by ECX - to get information about all the cache levels, it is necessary to invoke CPUID repeatedly, with EAX=4 or 8000'001Dh and ECX set to increasing values starting from 0 (0,1,2,...) until a sub-leaf not describing any caches (EAX[4:0]=0) is found. The sub-leaves that ...
