Hi. This had some problems in merge testing, I'm afraid:
On aarch64 host, warnings running tests/cpu-plug-test for i386 and s390 targets:
TEST: tests/cpu-plug-test... (pid=12602) /i386/cpu-plug/pc-i440fx-3.0/cpu-add/1x3x2&maxcpus=12: qemu-system-i386: warning: Invalid CPU topology deprecated: sockets (1) * cores (3) * threads (2) != maxcpus (12) [...]
(plus similar ppc64, x86_64 targets)
Ouch. Apologies.
Can we please do something make sure "make check" will fail on these cases? I'd like to be able to trust CI systems like travis-ci.
we probably don't want make check fail on warning. Test was written with assumption that s/c/t tuples matches initially present CPUs, hence a warning. Would something like following fix the issue (local x86 build/test looks fixed with it)? diff --git a/tests/cpu-plug-test.c b/tests/cpu-plug-test.c index 3e93c8e..f4a677d 100644 --- a/tests/cpu-plug-test.c +++ b/tests/cpu-plug-test.c @@ -32,12 +32,12 @@ static void test_plug_with_cpu_add(gconstpointer data) unsigned int i; args = g_strdup_printf("-machine %s -cpu %s " - "-smp sockets=%u,cores=%u,threads=%u,maxcpus=%u", + "-smp 1,sockets=%u,cores=%u,threads=%u,maxcpus=%u", s->machine, s->cpu_model, s->sockets, s->cores, s->threads, s->maxcpus); qtest_start(args); - for (i = s->sockets * s->cores * s->threads; i < s->maxcpus; i++) { + for (i = 1; i < s->maxcpus; i++) { response = qmp("{ 'execute': 'cpu-add'," " 'arguments': { 'id': %d } }", i); g_assert(response); @@ -56,7 +56,7 @@ static void test_plug_without_cpu_add(gconstpointer data) QDict *response; args = g_strdup_printf("-machine %s -cpu %s " - "-smp sockets=%u,cores=%u,threads=%u,maxcpus=%u", + "-smp 1,sockets=%u,cores=%u,threads=%u,maxcpus=%u", s->machine, s->cpu_model, s->sockets, s->cores, s->threads, s->maxcpus); qtest_start(args); @@ -79,12 +79,12 @@ static void test_plug_with_device_add_x86(gconstpointer data) unsigned int s, c, t; args = g_strdup_printf("-machine %s -cpu %s " - "-smp sockets=%u,cores=%u,threads=%u,maxcpus=%u", + "-smp 1,sockets=%u,cores=%u,threads=%u,maxcpus=%u", td->machine, td->cpu_model, td->sockets, td->cores, td->threads, td->maxcpus); qtest_start(args); - for (s = td->sockets; s < td->maxcpus / td->cores / td->threads; s++) { + for (s = 1; s < td->sockets; s++) { for (c = 0; c < td->cores; c++) { for (t = 0; t < td->threads; t++) { char *id = g_strdup_printf("id-%i-%i-%i", s, c, t); @@ -113,7 +113,7 @@ static void test_plug_with_device_add_coreid(gconstpointer data) td->sockets, td->cores, td->threads, td->maxcpus); qtest_start(args); - for (c = td->cores; c < td->maxcpus / td->sockets / td->threads; c++) { + for (c = 1; c < td->cores; c++) { char *id = g_strdup_printf("id-%i", c); qtest_qmp_device_add(td->device_model, id, "{'core-id':%u}", c); g_free(id); @@ -148,7 +148,7 @@ static void add_pc_test_case(const char *mname) data->sockets = 1; data->cores = 3; data->threads = 2; - data->maxcpus = data->sockets * data->cores * data->threads * 2; + data->maxcpus = data->sockets * data->cores * data->threads; if (g_str_has_suffix(mname, "-1.4") || (strcmp(mname, "pc-1.3") == 0) || (strcmp(mname, "pc-1.2") == 0) || @@ -203,7 +203,7 @@ static void add_pseries_test_case(const char *mname) data->sockets = 2; data->cores = 3; data->threads = 1; - data->maxcpus = data->sockets * data->cores * data->threads * 2; + data->maxcpus = data->sockets * data->cores * data->threads; path = g_strdup_printf("cpu-plug/%s/device-add/%ux%ux%u&maxcpus=%u", mname, data->sockets, data->cores, @@ -229,7 +229,7 @@ static void add_s390x_test_case(const char *mname) data->sockets = 1; data->cores = 3; data->threads = 1; - data->maxcpus = data->sockets * data->cores * data->threads * 2; + data->maxcpus = data->sockets * data->cores * data->threads; data2 = g_memdup(data, sizeof(PlugTestData)); data2->machine = g_strdup(data->machine);
