The vtd_generate_msi_message() in intel-iommu is used to construct a MSI
Message from IRQ. A similar function will be needed when we add interrupt
remapping support in amd-iommu. Moving the function in common file to
avoid the code duplication. Rename it to x86_iommu_irq_to_msi_message().
There is no logic changes in the code flow.

We should handle VTD_FR_CONTEXT_ENTRY_P properly when synchronizing
shadow page tables.  Having invalid context entry there is perfectly
valid when we move a device out of an existing domain.  When that
happens, instead of posting an error we invalidate the whole region.

Without this patch, QEMU will crash if we do these steps:

(1) start QEMU with VT-d IOMMU and two 10G NICs (ixgbe)
(2) bind the NICs with vfio-pci in the guest
(3) start testpmd with the NICs applied
(4) stop testpmd
(5) rebind the NIC back to ixgbe kernel driver

The patch should fix it.

There are two callers for vtd_sync_shadow_page_table_range(): one
provided a valid context entry and one not.  Move that fetching
operation into the caller vtd_sync_shadow_page_table() where we need to
fetch the context entry.

Meanwhile, remove the error_report_once() directly since we're already
tracing all the error cases in the previous call.  Instead, return error
number back to caller.  This will not change anything functional since
callers are dropping it after all.

We do this move majorly because we want to do something more later in
vtd_sync_shadow_page_table().

QEMU is not handling the global DMAR switch well, especially when from
"on" to "off".

Let's first take the example of system reset.

Assuming that a guest has IOMMU enabled.  When it reboots, we will drop
all the existing DMAR mappings to handle the system reset, however we'll
still keep the existing memory layouts which has the IOMMU memory region
enabled.  So after the reboot and before the kernel reloads again, there
will be no mapping at all for the host device.  That's problematic since
any software (for example, SeaBIOS) that runs earlier than the kernel
after the reboot will assume the IOMMU is disabled, so any DMA from the
software will fail.

For example, a guest that boots on an assigned NVMe device might fail to
find the boot device after a system reboot/reset and we'll be able to
observe SeaBIOS errors if we capture the debugging log:

  WARNING - Timeout at nvme_wait:144!

Meanwhile, we should see DMAR errors on the host of that NVMe device.
It's the DMA fault that caused a NVMe driver timeout.

The correct fix should be that we do proper switching of device DMA
address spaces when system resets, which will setup correct memory
regions and notify the backend of the devices.  This might not affect
much on non-assigned devices since QEMU VT-d emulation will assume a
default passthrough mapping if DMAR is not enabled in the GCMD
register (please refer to vtd_iommu_translate).  However that's required
for an assigned devices, since that'll rebuild the correct GPA to HPA
mapping that is needed for any DMA operation during guest bootstrap.

Besides the system reset, we have some other places that might change
the global DMAR status and we'd better do the same thing there.  For
example, when we change the state of GCMD register, or the DMAR root
pointer.  Do the same refresh for all these places.  For these two
places we'll also need to explicitly invalidate the context entry cache
and iotlb cache.

Using a wildcard like this is a bad idea, because if a new

and so no symlink is added for the new file. This can cause
tests to spuriously fail when they can't find their data.
Instead, it's better to symlink an entire directory of

(We can't just change the existing tests/acpi-test-data/

a developer switched git branches from one after that change

Coldfire defines an "Unsupported instruction" exception if execution
of a valid instruction is attempted but the required hardware is not
present in the processor.

We use it with instructions that are in fact undefined or illegal,
and the exception expected in this case by the kernel is the
illegal exception, so this patch fixes that.

Some time ago, I proposed to use an (eval) in .dir-locals.el to set
the mode for all json files and Makefile. Unfortunately, this isn't
safe, and emacs will prompt the user, which isn't very friendly.

Fortunately, editorconfig provides a special config key which does
allow to set the emacs mode. Add a few missing entries and set the
emacs mode.

Update top comment to provide a short summary about the file and the
IDE plugins while at it.
