• ARMv7-A: What is "Fault not on a stage 2 translation for a stage 1 translation table walk"?
    Hi all, I'm trying to boot Linux on my hypervisor like environment. In booting process, unexpected hyper trap was occurred and became hyp mode. In hyp mode, the Hyp Syndrome Register (HSR) value is 0x93830006...

  • 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...

  • 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...
