    OpenSparc T1 - Instruction fetch from ASI_REAL

    924125
      For my reaserch activities, i need to utilize the ASI_REAL address space for fetch instructions from this ASI space and exploit the instruction_real_translation_miss handler in i-TLB misses (iReal miss). How can i fetch instructions from an alternate space in T1;

      According to the supplement T1 manual, when instruction fetches occur, the implicit ASI for instruction fetching is ASI_NUCLEUS. Is there an option to select an other ASI for instruction fetching, in a simulator way that LDXA/STXA workd for load/store operations;

      Thank you in advance,
      Giorgos
