This enables the device to be made available during the setup of the Old World
machine. In order to pass back the previous set of IRQs we temporarily introduce
a new pic_irqs parameter until it can be removed.
An additional benefit of this change is that it is also possible to remove the
pic_mem pointer used for macio by accessing the memory region via sysbus.

Now that the ESCC device is instantiated directly via qdev, move it to within
the macio device and wire up the IRQs and memory regions using the sysbus API.
This enables to remove the now-obsolete escc_mem parameter to the macio_init()
function.
(Note this patch also contains small touch-ups to the formatting in
macio_escc_legacy_setup() and ppc_heathrow_init() in order to keep checkpatch
happy)

VSMT must be set in order to compute VCPU ids. This means that the
following functions must not be called before spapr_set_vsmt_mode()
was called:
- spapr_vcpu_id()
- spapr_is_thread0_in_vcore()
- xics_max_server_number()
We had a recent regression where the latter would be called before VSMT
was set, and broke migration of some old machine types. This patch
adds assert() in the above functions to avoid problems in the future.
Also, since VSMT is really a CPU related thing, spapr_set_vsmt_mode() is
now called from spapr_init_cpus(), just before the first VSMT user.

Some older machine types create more ICPs than needed. We hence
need to register up to xics_max_server_number() dummy ICPs to
accomodate the migration of these machine types.
Recent VSMT rework changed xics_max_server_number() to return
DIV_ROUND_UP(max_cpus * spapr->vsmt, smp_threads)
instead of
DIV_ROUND_UP(max_cpus * kvmppc_smt_threads(), smp_threads);
The change is okay but it requires spapr->vsmt to be set, which
isn't the case with the current code. This causes the formula to
return zero and we don't create dummy ICPs. This breaks migration
of older guests as reported here:
https://bugzilla.redhat.com/show_bug.cgi?id=1549087
The dummy ICP workaround doesn't really have a dependency on XICS
itself. But it does depend on proper VCPU id numbering and it must
be applied before creating vCPUs (ie, creating real ICPs). So this
patch moves the workaround to spapr_init_cpus(), which already
assumes VSMT to be set.

Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
Commit 5d0fb1508e "spapr: consolidate the VCPU id numbering logic
in a single place" introduced a helper to detect thread0 of a virtual
core based on its VCPU id. This is used to create CPU core nodes in
the DT, but it is broken in TCG.
$ qemu-system-ppc64 -nographic -accel tcg -machine dumpdtb=dtb.bin \
-smp cores=16,maxcpus=16,threads=1
$ dtc -f -O dts dtb.bin | grep POWER8
PowerPC,POWER8@0 {
PowerPC,POWER8@8 {
instead of the expected 16 cores that we get with KVM:
$ dtc -f -O dts dtb.bin | grep POWER8
PowerPC,POWER8@0 {
PowerPC,POWER8@8 {
PowerPC,POWER8@10 {
PowerPC,POWER8@18 {
PowerPC,POWER8@20 {
PowerPC,POWER8@28 {
PowerPC,POWER8@30 {
PowerPC,POWER8@38 {
PowerPC,POWER8@40 {
PowerPC,POWER8@48 {
PowerPC,POWER8@50 {
PowerPC,POWER8@58 {
PowerPC,POWER8@60 {
PowerPC,POWER8@68 {
PowerPC,POWER8@70 {
PowerPC,POWER8@78 {
This happens because spapr_get_vcpu_id() maps VCPU ids to
cs->cpu_index in TCG mode. This confuses the code in
spapr_is_thread0_in_vcore(), since it assumes thread0 VCPU
ids to have a spapr->vsmt spacing.
spapr_get_vcpu_id(cpu) % spapr->vsmt == 0
Actually, there's no real reason to expose cs->cpu_index instead
of the VCPU id, since we also generate it with TCG. Also we already
set it explicitly in spapr_set_vcpu_id(), so there's no real reason
either to call kvm_arch_vcpu_id() with KVM.
This patch unifies spapr_get_vcpu_id() to always return the computed
VCPU id both in TCG and KVM. This is one step forward towards KVM<->TCG
migration.

If netdev_add tap,id=net0,...,vhost=on failed in net_init_tap_one(),
the followed up device_add virtio-net-pci,netdev=net0 will fail
too, prints:
TUNSETOFFLOAD ioctl() failed: Bad file descriptor TUNSETOFFLOAD
ioctl() failed: Bad file descriptor
The reason is that the fd of tap is closed when error occured after
calling net_init_tap_one().
The fd should be closed when calling net_init_tap_one failed:
- if tap_set_sndbuf() failed
- if tap_set_sndbuf() succeeded but vhost failed to open or
initialize with vhostforce flag on
- with wrong vhost command line parameter
The fd should not be closed just because vhost failed to open or
initialize but without vhostforce flag. So the followed up
device_add can fall back to userspace virtio successfully.

The legacy "-net" option can be quite confusing for the users since most
people do not expect to get a "vlan" hub between their emulated guest
hardware and the host backend. But so far, we are also not able to get
rid of "-net" completely, since it is the only way to configure on-board
NICs that can not be instantiated via "-device" yet. It's also a little
bit shorter to type "-net nic -net tap" instead of "-device xyz,netdev=n1
-netdev tap,id=n1".
So what we need is a new convenience option that is shorter to type than
the full -device + -netdev stuff, and which can be used to configure the
on-board NICs that can not be handled via -device yet. Thus this patch now
provides such a new option "--nic": It adds an entry in the nd_table to
configure a on-board / default NIC, creates a host backend and connects
the two directly, without a confusing "vlan" hub inbetween.
