[Qemu-devel] [PATCH 0/3] target-arm: fix mmu access protection emulation

[Juha Riihimäki]

The ARM VMSAv6 emulation does not correctly ignore access protection
checks for manager domain translation table descriptors. This causes
ARM Linux kernel to hang during initialization for ARMv7 CPUs. However
that has so far been hidden by another emulation bug where the cp15
c1 system control register has an invalid reset value for the emulated
ARMv6 and ARMv7 processors indicating an earlier processor revision
instead and thus making QEMU run the MMU emulation in ARMv5 mode.

This patch series fixes the access protection emulation in the ARM
MMU emulation (1) and introduces correct cp15 c1 system control
register values for the ARM1136, Cortex-A8 and Cortex-A9 cores (2,3).

  target-arm: fix vmsav6 access control
  target-arm: correct cp15 c1_sys reset value for arm1136 and cortex-a9

  target-arm: correct cp15 c1_sys reset value for cortex-a8
