Commit 71054d8841b4 introduced x86_msi_ops.setup_hpet_msi
to setup hpet MSI irq when irq remapping enabled.
This caused a regression of hpet MSI irq remapping.
Original code flow before commit 71054d8841b4:
hpet_setup_msi_irq()
arch_setup_hpet_msi()
Hi Yijing,
There's an effort to refine the remapping interface by
using hierarchy irqdomain, which plans to kill all these interfaces.

We need to ensure that the IOMMUs in the system have a chance to perform
some basic initialisation before we start adding masters to them.
This patch adds a call to of_iommu_init before of_platform_populate.

IOMMU drivers must be initialised before any of their upstream devices,
otherwise the relevant iommu_ops won't be configured for the bus in
question. To solve this, a number of IOMMU drivers use initcalls to
initialise the driver before anything has a chance to be probed.
Whilst this solves the
This patch extends of_dma_configure so that it sets up the IOMMU for a
device, as well as the coherent/non-coherent DMA mapping ops.

This patch plumbs the existing ARM IOMMU DMA infrastructure (which isn't
actually called outside of a few drivers) into arch_setup_dma_ops, so
that we can use IOMMUs for DMA transfers in a more generic fashion.
Since this significantly complicates the arch_setup_dma_ops function,
it is moved out
Hi all,
Here is version three of the RFC I've previously posted here:
RFCv1:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-August/283023.html
RFCv2:
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/283752.html
Changes since RFCv2 include:
- Put the
This patch adds a new function to the iommu_ops structure to allow an
OF device to be added to a specific IOMMU instance using the recently
merged generic devicetree binding for IOMMUs. The callback (of_xlate)
takes a struct device representing the master and an of_phandle_args
representing the
set_arch_dma_coherent_ops is called from of_dma_configure in order to
swizzle the architectural dma-mapping functions over to a cache-coherent
implementation. This is currently implemented only for ARM.
In anticipation of re-using this mechanism for IOMMU-backed dma-mapping
ops too, this patch
The generic IOMMU device-tree bindings can be used to add arbitrary OF
masters to an IOMMU with a compliant binding.
This patch introduces of_iommu_configure, which does exactly that. A
list of iommu_dma_mapping structures are created for each device, which
represent the set of IOMMU instances
