Subject: [PATCH 0/6] Intel IOMMU debugfs support
Date: Thu, 12 Oct 2017 17:03:36 -0700 [thread overview]
Message-ID: <1507853022-136228-1-git-send-email-sohil.mehta@intel.com> (raw)
Hi all,
This series aims to add debugfs support for Intel IOMMU. It exposes IOMMU
registers, internal context and dumps individual table entries to help debug
Intel IOMMUs.
The first patch does the ground work for the following patches by creating a new
Kconfig option - INTEL_IOMMU_DEBUG. It also reorganizes some Intel IOMMU data
structures. The next five patches add debugfs support for IOMMU context
internals, extended context, register contents, PASID internals, and Interrupt
remapping in that order. The information can be accessed in sysfs at
'/sys/kernel/debug/intel_iommu/'.
Regards,
Sohil
