* numa: mirror cpu to node mapping in MachineState::possible_cpusIgor Mammedov2017-05-111-0/+96
| | | | | | | | | | | | | | | | | | | Introduce machine_set_cpu_numa_node() helper that stores node mapping for CPU in MachineState::possible_cpus. CPU and node it belongs to is specified by 'props' argument. Patch doesn't remove old way of storing mapping in numa_info[X].node_cpu as removing it at the same time makes patch rather big. Instead it just mirrors mapping in possible_cpus and follow up per target patches will switch to possible_cpus and numa_info[X].node_cpu will be removed once there isn't any users left.

* numa: equally distribute memory on nodesLaurent Vivier2017-05-111-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When there are more nodes than available memory to put the minimum allowed memory by node, all the memory is put on the last node. This is because we put (ram_size / nb_numa_nodes) & ~((1 << mc->numa_mem_align_shift) - 1); on each node, and in this case the value is 0. This is particularly true with pseries, as the memory must be aligned to 256MB. To avoid this problem, this patch uses an error diffusion algorithm [1] to distribute equally the memory on nodes. We introduce numa_auto_assign_ram() function in MachineClass to keep compatibility between machine type versions. The legacy function is used with pseries-2.9, pc-q35-2.9 and pc-i440fx-2.9 (and previous), the new one with all others. Example: qemu-system-ppc64 -S -nographic -nodefaults -monitor stdio -m 1G -smp 8 \ -numa node -numa node -numa node \ -numa node -numa node -numa node Before: (qemu) info numa 6 nodes node 0 cpus: 0 6 node 0 size: 0 MB node 1 cpus: 1 7 node 1 size: 0 MB node 2 cpus: 2 node 2 size: 0 MB node 3 cpus: 3 node 3 size: 0 MB node 4 cpus: 4 node 4 size: 0 MB node 5 cpus: 5 node 5 size: 1024 MB After: (qemu) info numa 6 nodes node 0 cpus: 0 6 node 0 size: 0 MB node 1 cpus: 1 7 node 1 size: 256 MB node 2 cpus: 2 node 2 size: 0 MB node 3 cpus: 3 node 3 size: 256 MB node 4 cpus: 4 node 4 size: 256 MB node 5 cpus: 5 node 5 size: 256 MB [1] https://en.wikipedia.org/wiki/Error_diffusion Signed-off-by: Laurent Vivier <lvivier@redhat.com> Message-Id: <20170502162955.1610-2-lvivier@redhat.com> Reviewed-by: Eduardo Habkost <ehabkost@redhat.com> [ehabkost: s/ram_size/size/ at numa_default_auto_assign_ram()] Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>
* numa,spapr: align default numa node memory size to 256MBLaurent Vivier2017-03-221-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | Since commit 224245b ("spapr: Add LMB DR connectors"), NUMA node memory size must be aligned to 256MB (SPAPR_MEMORY_BLOCK_SIZE). But when "-numa" option is provided without "mem" parameter, the memory is equally divided between nodes, but 8MB aligned. This can be not valid for pseries. In that case we can have: $ ./ppc64-softmmu/qemu-system-ppc64 -m 4G -numa node -numa node -numa node qemu-system-ppc64: Node 0 memory size 0x55000000 is not aligned to 256 MiB With this patch, we have: (qemu) info numa 3 nodes node 0 cpus: 0 node 0 size: 1280 MB node 1 cpus: node 1 size: 1280 MB node 2 cpus: node 2 size: 1536 MB Signed-off-by: Laurent Vivier <lvivier@redhat.com> Signed-off-by: David Gibson <david@gibson.dropbear.id.au>
* machine: Convert abstract typename on compat_props to subclass namesEduardo Habkost2017-03-141-3/+36
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original problem description by Greg Kurz: > Since commit "9a4c0e220d8a hw/virtio-pci: fix virtio > behaviour", passing -device virtio-blk-pci.disable-modern=off > has no effect on 2.6 machine types because the internal > virtio-pci.disable-modern=on compat property always prevail. The same bug also affects other abstract type names mentioned on compat_props by machine-types: apic-common, i386-cpu, pci-device, powerpc64-cpu, s390-skeys, spapr-pci-host-bridge, usb-device, virtio-pci, x86_64-cpu. The right fix for this problem is to make sure compat_props and -global options are always applied in the order they are registered, instead of reordering them based on the type hierarchy. But changing the ordering rules of -global is risky and might break existing configurations, so we shouldn't do that on a stable branch. This is a temporary hack that will work around the bug when registering compat_props properties: if we find an abstract class on compat_props, register properties for all its non-abstract subtypes instead. This will make sure -global won't be overridden by compat_props, while keeping the existing ordering rules on -global options. Note that there's one case that won't be fixed by this hack: "-global spapr-pci-vfio-host-bridge.<option>=<value>" won't be able to override compat_props, because spapr-pci-host-bridge is not an abstract class.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the Error typedef. Since then, we've moved to include qemu/osdep.h everywhere. Its file comment explains: "To avoid getting into possible circular include dependencies, this file should not include any other QEMU headers, with the exceptions of config-host.h, compiler.h, os-posix.h and os-win32.h, all of which are doing a similar job to this file and are under similar constraints." qapi/error.h doesn't do a similar job, and it doesn't adhere to similar constraints: it includes qapi-types.h. That's in excess of 100KiB of crap most .c files don't actually need. Add the typedef to qemu/typedefs.h, and include that instead of qapi/error.h. Include qapi/error.h in .c files that need it and don't get it now. Include qapi-types.h in qom/object.h for uint16List. Update scripts/clean-includes accordingly. Update it further to match reality: replace config.h by config-target.h, add sysemu/os-posix.h, sysemu/os-win32.h. Update the list of includes in the qemu/osdep.h comment quoted above similarly. This reduces the number of objects depending on qapi/error.h from "all of them" to less than a third. Unfortunately, the number depending on qapi-types.h shrinks only a little.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Similar to the previous patch, it's nice to have all functions in the tree that involve a visitor and a name for conversion to or from QAPI to consistently stick the 'name' parameter next to the Visitor parameter.

* qapi: Swap visit_* arguments for consistent 'name' placementEric Blake2016-02-081-5/+5

This can be a bit confusing to have to mentally swap the parameter order to match JSON order. It's particularly bad for visit_start_struct(), where the 'name' parameter is smack in the middle of the otherwise-related group of 'obj, kind, size' parameters! It's time to do a global swap of the parameter ordering, so that the 'name' parameter is always immediately after the Visitor argument. Additional reason in favor of the swap: the existing include/qjson.h prefers listing 'name' first in json_prop_*(), and I have plans to unify that file with the qapi visitors; listing 'name' first in qapi will minimize churn to the (admittedly few) qjson.h clients. Later patches will then fix docs, object.h, visitor-impl.h, and those clients to match. Done by first patching scripts/qapi*.py by hand to make generated files do what I want, then by running the following Coccinelle script to affect the rest of the code base: $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'` I then had to apply some touchups (Coccinelle insisted on TAB indentation in visitor.h, and botched the signature of visit_type_enum() by rewriting 'const char *const strings[]' to the syntactically invalid 'const char*const[] strings'). The movement of parameters is sufficient to provoke compiler errors if any callers were missed. // Part 1: Swap declaration order @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_start_struct -(TV v, TObj OBJ, T1 ARG1, const char *name, T2 ARG2, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type bool, TV, T1; identifier ARG1; @@ bool visit_optional -(TV v, T1 ARG1, const char *name) +(TV v, const char *name, T1 ARG1) { ... } @@ type TV, TErr, TObj, T1; identifier OBJ, ARG1; @@ void visit_get_next_type -(TV v, TObj OBJ, T1 ARG1, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, TErr errp) { ... } @@ type TV, TErr, TObj, T1, T2; identifier OBJ, ARG1, ARG2; @@ void visit_type_enum -(TV v, TObj OBJ, T1 ARG1, T2 ARG2, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, T1 ARG1, T2 ARG2, TErr errp) { ... } @@ type TV, TErr, TObj; identifier OBJ; identifier VISIT_TYPE =~ "^visit_type_"; @@ void VISIT_TYPE -(TV v, TObj OBJ, const char *name, TErr errp) +(TV v, const char *name, TObj OBJ, TErr errp) { ... } // Part 2: swap caller order @@ expression V, NAME, OBJ, ARG1, ARG2, ERR; identifier VISIT_TYPE =~ "^visit_type_"; @@ ( -visit_start_struct(V, OBJ, ARG1, NAME, ARG2, ERR) +visit_start_struct(V, NAME, OBJ, ARG1, ARG2, ERR) | -visit_optional(V, ARG1, NAME) +visit_optional(V, NAME, ARG1) | -visit_get_next_type(V, OBJ, ARG1, NAME, ERR) +visit_get_next_type(V, NAME, OBJ, ARG1, ERR) | -visit_type_enum(V, OBJ, ARG1, ARG2, NAME, ERR) +visit_type_enum(V, NAME, OBJ, ARG1, ARG2, ERR) | -VISIT_TYPE(V, OBJ, NAME, ERR) +VISIT_TYPE(V, NAME, OBJ, ERR) ) Signed-off-by: Eric Blake <eblake@redhat.com> Reviewed-by: Marc-André Lureau <marcandre.lureau@redhat.com> Message-Id: <1454075341-13658-19-git-send-email-eblake@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>

| | | | | | | | | | | | | | | | We now always send a JSON blob describing the migration file format as part of the migration stream. However, some tools built around QEMU have proven to stumble over this. This patch gives the user the chance to disable said self-describing part of the migration stream. To disable vmdesc submission, just add -machine suppress-vmdesc=on to your QEMU command line. Signed-off-by: Alexander Graf <agraf@suse.de> Signed-off-by: Juan Quintela <quintela@redhat.com>
