[Xen-devel] [PATCH v2 0/3] Set SMMU s2 input-size based on p2m tables

["Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxx>]

From: "Edgar E. Iglesias" <edgar.iglesias@xxxxxxxxxx>

Hi,

This is a fix for the issue I'm seeing on ZynqMP with missmatched
setup of the SMMU and the shared p2m page-tables with the CPU.

This implementes a global p2m_pfn_bits cap for S2 input-size as
discussed in the previous RFC.

Best regards,
Edgar

v1 -> v2:
* Use a global pfn bitsize instead of a per-domain one.

  xen/arm: Re-order iommu_setup to after setup_virt_paging
  xen/arm: Add p2m_pfn_bits
  xen/iommu: arm: Use p2m_pfn_bits as stage2 input size
