Subject: [Patch Part3 V7 0/8] Enable support of Intel DMAR device hotplug
Date: Sun, 09 Nov 2014 14:47:55 +0000 [thread overview]
Message-ID: <1415544483-27990-1-git-send-email-jiang.liu@linux.intel.com> (raw)
When hot plugging a descrete IOH or a physical processor with embedded
IIO, we need to handle DMAR(or IOMMU) unit in the PCIe host bridge if
DMAR is in use. This patch set tries to enhance current DMAR/IOMMU/IR
drivers to support hotplug and is based on latest Linus master branch.
All prerequisite patches to support DMAR device hotplug have been merged
into the mainstream kernel, and this is the last patch set to enable
DMAR device hotplug.
You may access the patch set at:
https://github.com/jiangliu/linux.git iommu/hotplug_v7
This patch set has been tested on Intel development machine.
Appreciate any comments and tests.
V6->V7:
1) Rebase to v3.18-rc3
V5->V6:
1) Fix a race condition found during review
2) Refine dmar_walk_resources() to dmar_walk_remapping_entries()
Patch 1-4 enhances DMAR framework to support hotplug
Patch 5 enhances Intel interrupt remapping driver to support hotplug
Patch 6 enhances error handling in Intel IR driver
Patch 7 enhance Intel IOMMU to support hotplug
Patch 8 enhance ACPI pci_root driver to handle DMAR units
Jiang Liu (8):
iommu/vt-d: Introduce helper function dmar_walk_resources()
iommu/vt-d: Dynamically allocate and free seq_id for DMAR units
iommu/vt-d: Implement DMAR unit hotplug framework
iommu/vt-d: Search for ACPI _DSM method for DMAR hotplug
iommu/vt-d: Enhance intel_irq_remapping driver to support DMAR unit
hotplug
iommu/vt-d: Enhance error recovery in function
intel_enable_irq_remapping()
iommu/vt-d: Enhance intel-iommu driver to support DMAR unit hotplug
pci, ACPI, iommu: Enhance pci_root to support DMAR device hotplug
