[PATCH 2/5] Xen/MCE: vMCE injection
Xen/MCE: vMCE injection
In our test for win8 guest mce, we find a bug that no matter what SRAO/SRAR
error xen inject to win8 guest, it always reboot.
The root cause is, current Xen vMCE logic inject vMCE# only to vcpu0, this is
not correct for Intel MCE (Under Intel arch, h/w generate MCE# to all CPUs).
This patch fix vMCE injection bug, injecting vMCE# to all vcpus.

Simultaneous Ring
I have a need to issue a dial command to a number:
same => n,Dial(${DIALGROUP1},${TIMER1},t)
After a number of seconds, let's say 10 seconds. I want to dial another set of numbers while continuing to ring, or interrupting the first group of numbers.
same => n,Dial(${DIALGROUP2},${TIMER1},t)
Is there a way to do this without interrupting the first call?
Thanks,

[PATCH 0/4] Add posted interrupt supporting
From: Yang Zhang <yang.z.zhang@Intel.com>
The follwoing patches are adding the Posted Interrupt supporting to Xen:
Posted Interrupt allows vAPIC interrupts to inject into guest directly
without any vmexit.
- When delivering a interrupt to guest, if target vcpu is running,
update Posted-interrupt requests bitmap and send a notification event
to the vcpu. Then the vcpu will handle this

Anyone succeeds HVM on latest x86-64 xen
I tried latest xen and linux-xen staging tree, but failed to run HVM
domain on x86-64 environment. domU creation is OK.
However the weird thing is not HVM domain itself. Instead system
crashed on dom0 context. I saw once with some stack dump that
xen''s page fault handler is executed on a dom0''s stack which then
causes nested page fault due to unable to fetch vcpu pointer.

Can we disable secondary_bus_reset in runtime?
I think we need this feature at least for debugging purpose, right?
Or, do we already have this feature?
Thanks,

[PATCH][ioemu] support the assignment of the VF of Intel 82599 10GbE Controller
The datasheet is available at
http://download.intel.com/design/network/datashts/82599_datasheet.pdf
See 'Table 9.7. VF PCIe Configuration Space' of the datasheet, the PCI
Express Capability Structure of the VF of Intel 82599 10GbE Controller looks
trivial, e.g., the PCI Express Capabilities Register is 0, so the Capability
Version is 0 and pt_pcie_size_init() would fail.

[PATCH] Fix write parameter masking for 32-bit guests.
Changeset 15046:e527b4ff1948 breaks 32-bit HVM guest: when req->size is
4, "1UL << 32" returns 1 in IA32 system, so the mask becomes 0 wrongly.
The attached patch fixes this by using 64-bit left-shift.

A race condition introduced by changeset 15175: Re-init hypercall stubs page after HVM save/restore
For an SMP Linux HVM guest with PV drivers inserted, when we do save/restore (or LiveMigration) for the guest, it might panic after it''s restored.
The panic point is inside ap_suspend():
....
while (info->do_spin) {
cpu_relax();
read_lock(&suspend_lock);
HYPERVISOR_yield(); ----> guest might panic on the invocation of this function.

[Patch] Add NMI Injection and Pending Support in VMX
Currently, Xen does not support injecting an NMI to HVM guest OS. Adding
this
feature is necessary for those softwares which depend on NMI to function
correctly,
such as KDB and oprofile.
The attached patch allows NMI to be injected to guest OS in NMIP capable
platforms.
It also enables to queue an NMI and then inject it as soon as possible.

[PATCH] Included reserved memory regions in dom0 iommu mappings
This adds a boolean boot parameter to xen to allow reserved memory
regions to be added to the iommu mappings for dom0. The parameter
is "iommu_include_reserved" and is off by default. A warning is
also traced when incorrect RMRR to system memory map values are
detected. This is being added to address some incorrect BIOS''s that
do not report correctly the requied reserved memory

[PATCH] Improve the current FLR logic
Hi, all,
The attached patches try to improve the current FLR logic.
The idea is: removing the FLR logic from hypervisor and adding the
improved logic in Control Panel.
The current FLR logic in hypervisor has some issues: 1) Dstate
transition is not guaranteed to properly clear the device state; 2) the
current code for PCIe FLR is actually buggy: PCI_EXP_DEVSTA_TRPND
