| | * | hrtimer: convert kvm-ia64 to the new hrtimer apisArjan van de Ven2008-09-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In order to be able to do range hrtimers we need to use accessor functions to the "expire" member of the hrtimer struct. This patch converts KVM-ia64 to these accessors. Signed-off-by: Arjan van de Ven <arjan@linux.intel.com>

It defines new machvec dig_vtd, hooks for IOMMU, DMAR table detection, cache line flush function, etc. For a generic kernel with CONFIG_DMAR=y, if Intel IOMMU is detected, dig_vtd is used for machinve vector. Otherwise, kernel falls back to dig machine vector. Kernel parameter "machvec=dig" or "intel_iommu=off" can be used to force kernel to boot dig machine vector.

Define helper functions for those address conversion. Cc: Jeremy Fitzhardinge <jeremy@goop.org> Signed-off-by: Isaku Yamahata <yamahata@valinux.co.jp> Signed-off-by: Tony Luck <tony.luck@intel.com>
| | * | | | | ia64/xen: add a necessary header file to compile include/xen/interface/xen.hIsaku Yamahata2008-10-17

Hopefully include/asm-x86/pvclock-abi.h would be moved to somewhere more generic. Another approach is to include include/asm-x86/pvclock-abi.h from include/asm-ia64/pvclock-abi.h. But this would break if/when x86 header files are moved under arch/x86. So for now, same definitions are duplicated as suggested by Tony.
