similar to: [PATCH 7/10] SMP support to Xen PM

Basic infrastructure for Xen S3 support with a common CPU context save/restore logic for both 32bit and 64bit. Wakeup code is split into two parts: - the first locates after trampoline code, to share all the tricks on the latter, like relocation base and identy mapping - the 2nd part locates in xen code segment, to do the actual CPU context restore Signed-off-by Ke Yu

New versions of tboot support ACPI GAS (Generic Address Structure) for handling sleep states. This required a change to the tboot_shared_t data structure that is not backwards compatible. This patch requires that new version makes use of GAS when invoking tboot on shutdown. Signed-off-by: Shane Wang <shane.wang@intel.com> Signed-off-by: Joseph Cihula <joseph.cihula@intel.com> diff

With the lake of iommu, dom0 must have a 1:1 memory mapping for all these guest physical address. When the ballon decides to give back a page to the kernel, this page must have the same address as previously. Otherwise, we will loose the 1:1 mapping and will break DMA-capable device.

Detect invalid/unsupported configurations in iommu_alloc() - offsets read from hardware must not lead to exceeding a single page (since only that much gets mapped). This covers the apparently not uncommon case of the address pointed to by a DMAR reading as all ones (Linux for example also checks for this). Further correct error handling of that function: Without storing the allocated "struct

Dom0 uses this hypercall to pass ACPI information to Xen. It is not very uncommon for more cpus to be listed in the ACPI tables than are present on the system, particularly on systems with a common BIOS for a 2 and 4 socket server varients. As Dom0 does not control the number of entries in the ACPI tables, and is required to pass everything it finds to Xen, reduce the ERR to an INFO.

Jan, This patch just used to stick all 1''s to MCi_CTL, it should not involve much argue, so I sent it separately. Thanks, Jinsong ==================== Xen/MCE: stick all 1''s to MCi_CTL of vMCE This patch is a middle-work patch, prepare for future new vMCE model.

These errata are fixed in stepping C-2. Unfortunately this chipset is very common and many BIOSes are not disabling remapping. We can

These plugins are intended to support virtualisable network hardware that can be directly accessed from the guest, bypassing dom0.
