      hw/arm/virt: don't use a15memmap directly · 4b280b72
      由 Andrew Jones 提交于 
      We should always go through VirtBoardInfo when we need the memmap.
To avoid using a15memmap directly, in this case, we need to defer
the max-cpus check from class init time to instance init time. In
class init we now use MAX_CPUMASK_BITS for max_cpus initialization,
which is the maximum QEMU supports, and also, incidentally, the
maximum KVM/gicv3 currently supports. Also, a nice side-effect of
delaying the max-cpus check is that we now get more appropriate
error messages for gicv2 machines that try to configure more than
123 cpus. Before this patch it would complain that the requested
number of cpus was greater than 123, but for gicv2 configs, it
should complain that the number is greater than 8.

      hw/arm/virt: Make block devices default to virtio · 4e2c0b2a
      由 Peter Maydell 提交于 
      Now we have virtio-pci, we can make the virt board's default block
device type be IF_VIRTIO. This allows users to use simplified
command lines that don't have to explicitly create virtio-pci-blk
devices; the -hda &c very short options now also work.

This means we also need to set no_cdrom to avoid getting a
default cdrom device -- this is needed because the virtio-blk
device will fail if it is connected to a block backend with
no media, which is what the default cdrom device typically is.
Providing a cdrom with media via -cdrom will succeed, but silently
create a device with non-removable medium. this is probably
not really what the user wants, but is the best we can do now.

Note that this change means that some command lines which used
to work (by accident) will stop working. Where a drive was connected
manually to a device but without 'if=none' being specified, we
used to treat this as an IDE drive, which we would then not autoplug
because the board doesn't support IDE. Now we will treat it as a
virtio disk and autoplug it, which means the attempt to use the
drive manually will fail:
  qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is already
  in use because it has been automatically connected to another device
  (did you need 'if=none' in the drive options?)
The command line will have to be changed to include 'if=none', as the
error message suggests.

      hw/arm/virt: fix cmdline parsing bug with CPU options and smp > 1 · 886bc7a0
      由 Ard Biesheuvel 提交于 
      The recently introduced feature that allows 32 bit guests to be
executed under KVM on a 64-bit host incorrectly handles the case
where more than 1 cpu is specified using '-smp N'

For instance, this invocation of qemu

  qemu-system-aarch64 -M virt -cpu cortex-a57,aarch64=off -smp 2

produces the following error

  qemu-system-aarch64: Expected key=value format, found aarch64

which is caused by the destructive parsing performed by
cpu_common_parse_features(), resulting in subsequent attempts
to parse the CPU option string (for each additional CPU) to fail.

So duplicate the string before parsing it, and free it directly
afterwards.
