x86: fix pv cpuid masking
Invert initial values of the variables parsed into from the command
line, so that completely clearing out one or more of the four bit
fields is possible.
Further, consolidate the command line parameter specifications into
a single place.
Finally, as per "Intel Virtualization Technology FlexMigration
Application Note" (http://www.intel.com/Assets/PDF/manual/323850.pdf),
also handle family 6 model 0x1f.
What remains open is the question whether pv_cpuid() shouldn't also
consume these masks.

x2APIC/VT-d: allocate iommu when create a drhd
A drhd is created when parse ACPI DMAR table, but drhd->iommu is not
allocated until iommu setup. But iommu is needed by x2APIC which will
enable interrupt remapping before iommu setup. This patch allocates
iommu when create drhd. And then drhd->ecap can be removed because
it's the same as iommu->ecap.

x2APIC/VT-d: improve interrupt remapping and queued invalidation enabling and disabling
x2APIC depends on interrupt remapping, so interrupt remapping needs to
be enabled before x2APIC. Usually x2APIC is not enabled
(x2apic_enabled=0) when enable interrupt remapping, although x2APIC
will be enabled later. So it needs to pass a parameter to set
interrupt mode in intremap_enable, instead of checking
x2apic_enable. This patch adds a parameter "eim" to intremap_enable to
achieve it. Interrupt remapping and queued invalidation are already
enabled when enable x2apic, so it needn't to enable them again when
setup iommu. This patch checks if interrupt remapping and queued
invalidation are already enable or not, and won't enable them if
already enabled. It does the similar in disabling, that's to say don't
disable them if already disabled.

x2APIC: improve enabling logic
This patch masks PIC and IOAPIC RTE's before x2APIC enabling, unmask
and restore them after x2APIC enabling. It also really enables
interrupt remapping before x2APIC enabling instead of just checking
interrupt remapping setting. This patch also handles all x2APIC
configuration including BIOS settings and command line
settings. Especially, it handles that BIOS hands over in x2APIC mode
(when there is apic id > 255). It checks if x2APIC is already enabled
by BIOS. If already enabled, it will disable interrupt remapping and
queued invalidation first, then enable them again.

vt-d: Fix ioapic write order in io_apic_write_remap_rte
At the end of io_apic_write_remap_rte, it writes new entry (remapped
interrupt) to ioapic. But it writes low 32 bits before high 32 bits,
it unmasks interrupt before writing high 32 bits if 'mask' bit in low
32 bits is cleared. Thus it may result in issues. This patch fixes
this issue by writing high 32 bits before low 32 bits.

vt-d: Fix ioapic_rte_to_remap_entry error path.
When ioapic_rte_to_remap_entry fails, currently it just writes value
to ioapic. But the 'mask' bit may be changed if it writes to the upper
half of RTE. This patch ensures to recover the original value of 'mask'
bit in this case.

msi: Avoid uninitialized msi descriptors
When __pci_enable_msix() returns early, output parameter (struct
msi_desc **desc) will not be initialized. On my machine, a Broadcom
BCM5709 nic has both MSI and MSIX capability blocks and when guest
tries to enable msix interrupts but __pci_enable_msix() returns early
for encountering a msi block, the whole system will crash for fatal
page fault immediately.

usb-list.patch Normal file

@ -0,0 +1,45 @@
"usb-hc-create" does not check usb-ver parameter. It allows 2/2.0/2.0usb/2.0aaa. While low level
driver doing hc create, it gets an integer by vssanf %d from usb-ver string, so there is no problem.
But 2/2.0/2.0usb/2.0aaa will be saved into VM config.
After that, while doing "usb-list", it cannot handle "2.0/2.0usb/2.0aaa" and will cause error:
Idx BE state usb-ver BE-path
Error: Invalid argument.
Usage: xm usb-list <Domain>
This patch is to let "usb-list" handle all usb-ver cases as low level driver does and won't cause error.
About this problem, I've submitted two patches to upstream before, but got no response. Information
could be referred to:
