[Xen-devel] [PATCH v2 0/6] unsafe big.LITTLE support

[Stefano Stabellini <sstabellini@xxxxxxxxxx>]

Hi all,

This series changes the initialization of two virtual registers to make
sure they match the value of the underlying physical cpu.

It also disables cpus different from the boot cpu, unless a newly
introduced command line option is specified. In that case, it explains
how to setup the system to avoid corruptions, which involves manually
specifying the cpu affinity of all domains, because the scheduler still
lacks big.LITTLE support.

Cheers,

Stefano

      xen/arm: Park CPUs with a MIDR different from the boot CPU.

Stefano Stabellini (5):
      xen/arm: make processor a per cpu variable
      xen/arm: read ACTLR on the pcpu where the vcpu will run
      xen/arm: make vpidr per vcpu
      xen/arm: read cacheline size when needed
      xen/arm: update the docs about heterogeneous computing
