Hi Peter,
That command line option doesn't work for boston, although I didn't get any
obvious error, no Ethernet card appears either.
Where can I get that arm image/command which can work well for you with "
-netdev user,id=mynet -device virtio-net-pci,netdev=mynet" ?
Anyway, if that command
We can now use the CPUClass hook instead of a named function.
Create a static tlb_fill function to avoid other changes within
cputlb.c. This also which also isolates the asserts implied.
Remove the named tlb_fill function from all of the targets.

Most of the existing users would continue around a loop which
would fault the tlb entry in via a normal load/store. But for
SVE we have a true non-faulting case which requires the new

I wrote these patches to help me debug an unplug failure. I expect
them to be helpful for others, too.

acpi/piix4: Convert debug printf()s to trace events
acpi/pcihp: Convert debug printf()s to trace events
acpi/pcihp: Add a few more trace points related to unplug

Do encryption/decryption in threads, like it is already done for
compression. This improves asynchronous encrypted io.

Move compression-on-threads to separate file. Encryption will be in it
too.

Background: decryption will be done in threads, to take benefit of it,
we should move it out of the lock first.
But let's go further: it turns out, that for locking around switch
cases we have only two variants: when we just do memset(0) not
releasing the lock (it is useless) and when we actually
Move generic part out of qcow2_co_do_compress, to reuse it for
encryption and rename things that would be shared with encryption path.

qcow2.h depends on block_int.h. Compilation isn't broken currently only
due to block_int.h always included before qcow2.h. Though, it seems
better to directly include block_int.h in qcow2.h.
