The AST2500 datasheet says:

S/W needs to clear this status bit to allow next data receiving
The Rx interrrupt done interrupt status bit needs to be cleared
explicitly before the next byt
and the bus interrupt should be lowered when all interrupts have been

Receive command handling may have to be deferred if a previous receive

Hello,
The interrupt model of the Aspeed I2C controller does handle correctly
the RX_DONE bit. As indicated in the AST2500 datasheet, the RX_DONE
bit needs to be cleared to allow mode data to be received. This series
fixes the behavior and delays the data reception until the bit has
been cleared.

Can I convert from internap snapshot to external snapshot?
If there's 3 snapshots in one qcow2, can I convert them all to external
snapshots?
In general case, what's difference between internal and external snapshot?
I mean in some user situation.
Ex: If I want to all snapshots in only one qcow2, I should use internal
snapshot.

Kernel commit 8fcc4b5923af ("kvm: nVMX: Introduce KVM_CAP_NESTED_STATE")
introduced new IOCTLs to extract and restore KVM internal state used to

Utilize these IOCTLs to add support of migration of VMs which are

Hi,
This series aims to add support for QEMU to be able to migrate VMs that
are running nested hypervisors. In order to do so, it utilizes the new
IOCTLs introduced in KVM commit 8fcc4b5923af ("kvm: nVMX: Introduce
KVM_CAP_NESTED_STATE") which were created for this purpose.

With this we get decent coverage of softfloat.c:
$ ./fp-test -r even:67.22% coverage
$ ./fp-test -r all: 73.11% coverage
Note that we do not yet test parts of softfloat.c that aren't
