Detailed Description

CheckerCPU class.

Dynamically verifies instructions as they are completed by making sure that the instruction and its results match the independent execution of the benchmark inside the checker. The checker verifies instructions in order, regardless of the order in which instructions complete. There are certain results that can not be verified, specifically the result of a store conditional or the values of uncached accesses. In these cases, and with instructions marked as "IsUnverifiable", the checker assumes that the value from the main CPU's execution is correct and simply copies that value. It provides a CheckerThreadContext (see checker/thread_context.hh) that provides hooks for updating the Checker's state through any ThreadContext accesses. This allows the checker to be able to correctly verify instructions, even with external accesses to the ThreadContext that change state.

Helper function used to generate the request for a single fragment of a memory access.

Takes care of setting up the appropriate byte-enable mask for the fragment, given the mask for the entire memory access.

Parameters
frag_addrStart address of the fragment.
sizeTotal size of the memory access in bytes.
flagsRequest flags.
byte_enableByte-enable mask for the entire memory access.
[out]frag_sizeFragment size.
[in,out]size_leftSize left to be processed in the memory access.
Returns
Pointer to the allocated Request, nullptr if the byte-enable mask is all-false for the fragment.
