* | xen/mapcache: store dma information in revmapcache entries for debuggingStefano Stabellini2017-05-161-2/+3
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Xen mapcache is able to create long term mappings, they are called "locked" mappings. The third parameter of the xen_map_cache call specifies if a mapping is a "locked" mapping. >From the QEMU point of view there are two kinds of long term mappings: [a] device memory mappings, such as option roms and video memory [b] dma mappings, created by dma_memory_map & friends After certain operations, ballooning a VM in particular, Xen asks QEMU kindly to destroy all mappings. However, certainly [a] mappings are present and cannot be removed. That's not a problem as they are not affected by balloonning. The *real* problem is that if there are any mappings of type [b], any outstanding dma operations could fail. This is a known shortcoming. In other words, when Xen asks QEMU to destroy all mappings, it is an error if any [b] mappings exist. However today we have no way of distinguishing [a] from [b]. Because of that, we cannot even print a decent warning. This patch introduces a new "dma" bool field to MapCacheRev entires, to remember if a given mapping is for dma or is a long term device memory mapping. When xen_invalidate_map_cache is called, we print a warning if any [b] mappings exist. We ignore [a] mappings. Mappings created by qemu_map_ram_ptr are assumed to be [a], while mappings created by address_space_map->qemu_ram_ptr_length are assumed to be [b]. The goal of the patch is to make debugging and system understanding easier.

* numa: remove node_cpu bitmaps as they are no longer usedIgor Mammedov2017-05-111-1/+0Star
| | | | | | | | | | | | | | | | | | | | Postfactum "CPU(s) present in multiple NUMA nodes" check was the last user of node_cpu bitmaps, but it's not need as machine_set_cpu_numa_node() does the similar check at the time mapping is set for cpus (i.e. when -numa cpus= is parsed) and ensures that cpu can be mapped only to one node. Remove duplicate check based on node_cpu bitmaps and since the last user is gone remove node_cpu as well, which completes internal transition from legacy bitmap based mapping storage to possible_cpus storage.

* numa: move source of default CPUs to NUMA node mapping into boardsIgor Mammedov2017-05-111-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Originally CPU threads were by default assigned in round-robin fashion. However it was causing issues in guest since CPU threads from the same socket/core could be placed on different NUMA nodes. Commit fb43b73b (pc: fix default VCPU to NUMA node mapping) fixed it by grouping threads within a socket on the same node introducing cpu_index_to_socket_id() callback and commit 20bb648d (spapr: Fix default NUMA node allocation for threads) reused callback to fix similar issues for SPAPR machine even though socket doesn't make much sense there. As result QEMU ended up having 3 default distribution rules used by 3 targets /virt-arm, spapr, pc/. In effort of moving NUMA mapping for CPUs into possible_cpus, generalize default mapping in numa.c by making boards decide on default mapping and let them explicitly tell generic numa code to which node a CPU thread belongs to by replacing cpu_index_to_socket_id() with @cpu_index_to_instance_props() which provides default node_id assigned by board to specified cpu_index.

* numa: equally distribute memory on nodesLaurent Vivier2017-05-111-2/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* numa: Allow setting NUMA distance for different NUMA nodesHe Chen2017-05-112-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch is going to add SLIT table support in QEMU, and provides additional option `dist` for command `-numa` to allow user set vNUMA distance by QEMU command. With this patch, when a user wants to create a guest that contains several vNUMA nodes and also wants to set distance among those nodes, the QEMU command would like: ``` -numa node,nodeid=0,cpus=0 \ -numa node,nodeid=1,cpus=1 \ -numa node,nodeid=2,cpus=2 \ -numa node,nodeid=3,cpus=3 \ -numa dist,src=0,dst=1,val=21 \ -numa dist,src=0,dst=2,val=31 \ -numa dist,src=0,dst=3,val=41 \ -numa dist,src=1,dst=2,val=21 \ -numa dist,src=1,dst=3,val=31 \ -numa dist,src=2,dst=3,val=21 \ ``` Signed-off-by: He Chen <he.chen@linux.intel.com> Message-Id: <1493260558-20728-1-git-send-email-he.chen@linux.intel.com> Reviewed-by: Igor Mammedov <imammedo@redhat.com> Reviewed-by: Andrew Jones <drjones@redhat.com> Signed-off-by: Eduardo Habkost <ehabkost@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We use fd_in_tag to find a GSource, fd_in_tag is return value of g_source_attach(GSource *source, GMainContext *context), the return value is unique only in the same context, so we may get the same values with different 'context' parameters. It is no problem to find the right fd_in_tag by using g_main_context_find_source_by_id(GMainContext *context, guint source_id) while there is only one default main context. But colo-compare tries to create/use its own context, and if we pass wrong 'context' parameter with right fd_in_tag, we will find a wrong GSource to handle. We tried to fix the related codes in commit b43decb015a6efeb9e3cdbdb80f6547ad7248a4c, but it didn't fix the bug completely, because we still have some codes didn't pass *right* context parameter for remove_fd_in_watch(). Let's fix it by record the GSource directly instead of fd_in_tag.
