This patch series implements Address Translation Service support for
the Intel IOMMU. The PCIe Endpoint that supports ATS capability can
request the DMA address translation from the IOMMU and cache the
translation itself. This can alleviate IOMMU TLB pressure and improve
the hardware performance
The PCIe ATS capability makes the Endpoint be able to request the
DMA address translation from the IOMMU and cache the translation
in the device side, thus alleviate IOMMU TLB pressure and improve
the hardware performance in the I/O virtualization environment.

The SR-IOV spec requires the Smallest Translation Unit and the

to be hardwired to 0. If a function is a Virtual Function, then and

This is just a first cut. It needs a fair bit of cleanup before it can be

I have some WIP patches that split out the host device bits into
separate files to get block-raw-posix down to the pure
external module compat hard codes tsc_khz as 200 if KERNEL_VERSION

This breaks kvmclock on hosts with different frequency.
While tsc_khz was only exported on 2.6.23, the majority of relevant
older v2.6 based distros seem to have it exported.

This series adds a new -smbios option for x86 that allows individual

basic path as the support for loading ACPI tables. While SMBIOS is
independent of ACPI, I chose to add the smbios_entry_add() function to
acpi.c because
