      Large page TLB flush · d4c430a8
      Paul Brook authored
      
      
      QEMU uses a fixed page size for the CPU TLB.  If the guest uses large
      pages then we effectively split these into multiple smaller pages, and
      populate the corresponding TLB entries on demand.
      
      When the guest invalidates the TLB by virtual address we must invalidate
      all entries covered by the large page.  However the address used to
      invalidate the entry may not be present in the QEMU TLB, so we do not
      know which regions to clear.
      
      Implementing a full vaiable size TLB is hard and slow, so just keep a
      simple address/mask pair to record which addresses may have been mapped by
      large pages.  If the guest invalidates this region then flush the
      whole TLB.

      target-arm: refactor cp15.c13 register access · 3f26c122
      Riku Voipio authored
      
      
      Access the cp15.c13 TLS registers directly with TCG ops instead of with
      a slow helper. If the the cp15 read/write was not TLS register access,
      fall back to the cp15 helper.
      
      This makes accessing __thread variables in linux-user when apps are compiled
      with -mtp=cp15 possible. legal cp15 register to acces from linux-user are
      already checked in cp15_user_ok.
      
      While at it, make the cp15.c13 Thread ID registers available only on
      ARMv6K and newer.
