Hi,
Is there any one, trying out cross compiling and running qemu on
aarch64 host. if so is there a development branch where this wrok is
progressing.
Some one could please let me know the plan/time frame, for qemu
on arm64 hosts running arm64 guests.
Regards,
Mike,
This one's nice and clear. A few comments in line.

Looking at the compile output, in fact ./hw/9pfs/virtio-9p-device.o did
not get compiled after commit ba1183da9a10b94611cad88c44a5c6df005f9b55.

Merge filter_features_for_kvm() and kvm_check_features_against_host().
Both functions made exactly the same calculations, the only difference
was that filter_features_for_kvm() changed the bits on cpu->features[],
and kvm_check_features_against_host() did error reporting.

This removes some duplication in the CPU feature checking and filtering code in
cpu.c, and as a nice side-effect, will make the "check" and "enforce" flags work
in TCG mode too.

target-i386: Simplify reporting of unavailable features
target-i386: Merge feature filtering/c
Instead of checking and calling unavailable_host_feature() once for each
bit, simply call the function (now renamed to
report_unavailable_features()) once for each feature word.

I hope to review it early next week.
Coverity is unhappy with the generated code. Nothing serious, just
heaps of valid DEADCODE defects topped off with a few bogus
FORWARD_NULL defects.
I had a look at the generator, and decided I don't want to mess with
it without decent test coverage. Unfortunately, a few features have
been added
