• Why there is no translation tables concatenation for stage 1 of VA translation?
    It is possible to concatenate tables in stage 2 and therefore gain performance by skipping a translation level. Since the HW must be set for it why not to enable concatenation in stage 1 as well and potentially...

  • Using stage 2 translation for VMs and stage 1 translation for native applications in the same system
    Hi Everyone, I have a virtualized environment (Armv8) where I have a virtual machine (EL1 and EL0) alongside some "native" applications running in EL0. I am using 2nd stage translation for isolation...
  • VMSAv8-64 Stage 2 address translation -- PA size forces use of concatenated translation tables
    This question is about VMSAv8-64's EL1&0 stage 2 translation regime. The use of concatenated translation tables for the initial lookup is presented, in the ARM ARM, as an optional alternative to the overhead...
