2018-03-06spapr: fix missing CPU core nodes in DT when running with TCGGreg Kurz
Commit 5d0fb1508e2d "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.

2018-03-05tap: setting error appropriately when calling net_init_tap_one()Jay Zhou
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. Suggested-by: Michael S.

2018-03-05net: Add a new convenience option "--nic" to configure default/on-board NICsThomas Huth
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.

Since they are also standing in the way for the upcoming 'vlan' clean-up, it's now time to remove them.

Move qapi-schema.json to qapi/, so it's next to its modules, and all files get generated to qapi/, not just the ones generated for modules. Consistently name the generated files qapi-MODULE.EXT: qmp-commands.[ch] become qapi-commands.[ch], qapi-event.[ch] become qapi-events.[ch], and qmp-introspect.[ch] become qapi-introspect.[ch]. This gets rid of the temporary hacks in scripts/qapi/commands.py, scripts/qapi/events.py, and scripts/qapi/common.py.

2018-03-02qapi: Empty out qapi-schema.jsonMarkus Armbruster
The previous commit improved compile time by including less of the generated QAPI headers. This is impossible for stuff defined directly in qapi-schema.json, because that ends up in headers that that pull in everything. Move everything but include directives from qapi-schema.json to new sub-module qapi/misc.json, then include just the "misc" shard where possible. It's possible everywhere, except: * monitor.c needs qmp-command.h to get qmp_init_marshal() * monitor.c, ui/vnc.c and the generated qapi-event-FOO.c need qapi-event.h to get enum QAPIEvent Perhaps we'll get rid of those some other day. Adding a type to qapi/migration.json now recompiles some 120 instead of 2300 out of 5100 objects.

2018-03-02Include less of the generated modular QAPI headersMarkus Armbruster
In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.

2018-03-02qapi: Generate separate .h, .c for each moduleMarkus Armbruster
Our qapi-schema.json is composed of modules connected by include directives, but the generated code is monolithic all the same: one qapi-types.h with all the types, one qapi-visit.h with all the visitors, and so forth. These monolithic headers get included all over the place. In my "build everything" tree, adding a QAPI type recompiles about 4800 out of 5100 objects. We wouldn't write such monolithic headers by hand. It stands to reason that we shouldn't generate them, either. Split up generated qapi-types.h to mirror the schema's modular structure: one header per module. Name the main module's header qapi-types.h, and sub-module D/B.json's header D/qapi-types-B.h. Mirror the schema's includes in the headers, so that qapi-types.h gets you everything exactly as before. If you need less, you can include one or more of the sub-module headers. To be exploited shortly. Split up qapi-types.c, qapi-visit.h, qapi-visit.c, qmp-commands.h, qmp-commands.c, qapi-event.h, qapi-event.c the same way. qmp-introspect.h, qmp-introspect.c and qapi.texi remain monolithic. The split of qmp-commands.c duplicates static helper function qmp_marshal_output_str() in qapi-commands-char.c and qapi-commands-misc.c. This happens when commands returning the same type occur in multiple modules. Not worth avoiding. Since I'm going to rename qapi-event.[ch] to qapi-events.[ch], and qmp-commands.[ch] to qapi-commands.[ch], name the shards that way already, to reduce churn. This requires temporary hacks in commands.py and events.py. Similarly, c_name() must temporarily be taught to munge '/' in common.py. They'll go away with the rename.
