This is the single most important commit of the last 4 years. This update the api and function that are called inside the 'core' main loop, as well as the components. It was first authored for RISC-V. This change has to be replicated on the Qemu side. The code compile for TRACE and TIMING but was not tested.
Remove the initial definition of the target for RISC-V, and add the header file for aarch64.
'boost_extension' contains files with source code copy-pasted from the boost library itself, or that extend the already existing definition. They were removed and replaced by the official latest boost library (1.84) api.
All compile error from using GCC-13 and boost 1.83 are fixed. This also reinsert some debug output, while using some std api instead of the boost ones.
This avoid a lot of leaking object because the heap was never freed, also the object is more or less staticaly used and could be replaced by a static class.
fix: inconsistant nameing of 'cores'
This bypass transform an uninitalized MMU into a perfect one. The purpose of this change is to allow the uArch simulator to keep processing cycles during boot time. That render flexus unusable for Boot time experiments.
The integer value passed to the function FLEXUS_start is used as an offset from the very first instruction generated by QEMU
Were never called
This is crucial to make QEMU advance alongside KnottyKraken
TAGE checkpointing fixed
feat: add BTB json ckpt (back) Because of the modification brought by TAGE to the BTB, it was necessary to work it out again.
This made all instruction directly fetched from the memory to have 0 has opcode.
This issue apparead only during Release compilation

Have you checked that it still can load KeenKraken ckpt (even the multicore ?) |

mostly adapted the checkpoint system to support para-flex. fixed a bug in the BTB init function that always initialize the set with 64 ways without considering the associativity
