[Xen-devel] [PATCH v4 26/28] tools/libxl: build DMAR table for a guest with one virtual VTD

A new logic is added to init_acpi_config(). The logic initializes some fields introduced for DMAR table. For PVH guest, the DMAR table is built as other tables. But for HVM guest, only the DMAR table is built in toolstack and pass through it to guest via existing mechanism. Signed-off-by: Chao

[Xen-devel] [PATCH v4 18/28] x86/vioapic: Hook interrupt delivery of vIOAPIC

[Xen-devel] [PATCH v4 12/28] x86/vvtd: decode interrupt attribute from IRTE

Without interrupt remapping, interrupt attributes can be extracted from msi message or IOAPIC RTE. However, with interrupt remapping enabled, the attributes are enclosed in the associated IRTE. This callback is for cases in which the caller wants to acquire interrupt attributes, for example: 1.

[Xen-devel] [PATCH v4 06/28] vtd: clean-up and preparation for vvtd

This patch contains following changes: - align register definitions - use MASK_EXTR to define some macros about extended capabilies rather than open-coding the masks - define fields of FECTL and FESTS as uint32_t rather than u64 since FECTL and FESTS are 32 bit registers. No functional changes.
