as title, I know there're two snapshots in qemu, but I don't know when to
use them well.
What I know is internal snapshot will save the info of L1 and L2 table in
the end of image but external snapshot won't because external snapshot
create new file to save cow data.
So when to use internal snaps

When we converted rbd to get rid of the older key/value-centric

file strings encoded in the old format.

This is a small test that will check for the ability to parse
both legacy and modern options for rbd.
The way the test is set up is for failure to occur, but without
having to wait to timeout on a non-existent rbd server. The error
messages in the success path show that the arguments were parsed.

When interrupt remapping is enabled, add a special IVHD device
(type IOAPIC) -- which is typically PCI device 14:0.0. Linux IOMMU driver
checks for this special device.

Register the interrupt remapping callback and read/write ops for the
amd-iommu-ir memory region.

Interrupt remapping needs kernel-irqchip={off|split} on both Intel and AMD
platforms. Move the check in common place.

Hi all,
I noticed that both qemu and seabios create the ACPI table.
Once I think he bios' ACPI table will overwrite the qemu's if seabios
compiled with CONFIG_ACPI.
But after I read this -->

There say:

Emulate the interrupt remapping support when guest virtual APIC is
not enabled.
See IOMMU spec: https://support.amd.com/TechDocs/48882_IOMMU.pdf
(section 2.2.5.1) for details information.
When VAPIC is not enabled, it uses interrupt remapping as defined in
Table 20 and Figure 15 from IOMMU spec.
This series adds the interrupt remapping support for amd-iommu device.
IOMMU spec is available at: https://support.amd.com/TechDocs/48882_IOMMU.pdf
To enable the interrupt remap use below qemu cli
# $QEMU \
-device amd-iommu,intremap=on
I have tested FC-28 and Ubuntu 18.04 guest.
Linux guest
Now that amd-iommu support interrupt remapping, enable the GASup in IVRS
table and GASup in extended feature register to indicate that IOMMU
support guest virtual APIC mode.
Note that the GAMSup is set to zero to indicate that Guest Virtual
APIC does not support advanced interrupt features (i.e v
If you need a Nios II GNU/Linux toolchain, I think the most recent
CodeBench Lite release will work:

We're planning on adding user-mode QEMU to the upcoming 2018.11
release that's actually what I've been testing it for. Results on

We can build some more cross-compilers using buildroot. This base
system contains simply the minimum number of tools required for
buildroot to work. We also download and unpack the buildroot source
tree as that will be common for all system deriving from it.

Now we have a docker image with a nios2 compiler we can add the bits

Hi,
tl;dr Nios II linux-user seems pretty broken
Following up on some mailing list queries about the state of Nios II
Thomas pointed out that buildroot could build cross-compilers for the
architecture. As a quick experiment I've enabled a docker based
buildroot and turned on tests/tcg for it.

This is to work around the limitations of the buildroot
