So move parsing outside CPU creation loop and do it only once. Parsing also should be done before any CPU is created so that features would affect the first CPU a well. This patch does that for all PowerPC machine types. It is based on previous work from Bharata: https://lists.nongnu.org/archive/html/qemu-devel/2016-06/msg07564.html Signed-off-by: Greg Kurz --- hw/ppc/e500.c | 2 ++ hw/ppc/mac_newworld.c | 1 + hw/ppc/mac_oldworld.c | 1 + hw/ppc/ppc.c | 26 ++++++++++++++++++++++++++ hw/ppc/ppc440_bamboo.c | 1 + hw/ppc/ppc4xx_devs.c | 1 + hw/ppc/prep.c | 1 + hw/ppc/spapr.c | 2 ++ hw/ppc/virtex_ml507.c | 1 + include/hw/ppc/ppc.h | 1 + 10 files changed, 37 insertions(+) diff --git a/hw/ppc/e500.c b/hw/ppc/e500.c index ff5d92e48dd9..b9221cc2c14a 100644 --- a/hw/ppc/e500.c +++ b/hw/ppc/e500.c @@ -814,6 +814,8 @@ void ppce500_init(MachineState *machine, PPCE500Params *params) machine->cpu_model = "e500v2_v30"; } + ppc_cpu_parse_features(machine->cpu_model); + irqs = g_malloc0(smp_cpus * sizeof(qemu_irq *)); irqs[0] = g_malloc0(smp_cpus * sizeof(qemu_irq) * OPENPIC_OUTPUT_NB); for (i = 0; i < smp_cpus; i++) { diff --git a/hw/ppc/mac_newworld.c b/hw/ppc/mac_newworld.c index ecd40914be45..366089085844 100644 --- a/hw/ppc/mac_newworld.c +++ b/hw/ppc/mac_newworld.c @@ -192,6 +192,7 @@ static void ppc_core99_init(MachineState *machine) machine->cpu_model = "G4"; #endif } + ppc_cpu_parse_features(machine->cpu_model); for (i = 0; i < smp_cpus; i++) { cpu = ppc_cpu_init(machine->cpu_model); if (cpu == NULL) { diff --git a/hw/ppc/mac_oldworld.c b/hw/ppc/mac_oldworld.c index 77fbdfffd4e2..5c2dc53cb584 100644 --- a/hw/ppc/mac_oldworld.c +++ b/hw/ppc/mac_oldworld.c @@ -112,6 +112,7 @@ static void ppc_heathrow_init(MachineState *machine) /* init CPUs */ if (machine->cpu_model == NULL) machine->cpu_model = "G3"; + ppc_cpu_parse_features(machine->cpu_model); for (i = 0; i < smp_cpus; i++) { cpu = ppc_cpu_init(machine->cpu_model); if (cpu == NULL) { diff --git a/hw/ppc/ppc.c b/hw/ppc/ppc.c index dc3d214009c5..313b3f0b9a51 100644 --- a/hw/ppc/ppc.c +++ b/hw/ppc/ppc.c @@ -33,6 +33,7 @@ #include "hw/timer/m48t59.h" #include "qemu/log.h" #include "qemu/error-report.h" +#include "qapi/error.h" #include "hw/loader.h" #include "sysemu/kvm.h" #include "kvm_ppc.h" @@ -1355,3 +1356,28 @@ PowerPCCPU *ppc_cpu_init(const char *cpu_model) { return POWERPC_CPU(cpu_generic_init(TYPE_POWERPC_CPU, cpu_model)); } + +void ppc_cpu_parse_features(const char *cpu_model) +{ + CPUClass *cc; + ObjectClass *oc; + const char *typename; + gchar **model_pieces; + + model_pieces = g_strsplit(cpu_model, ",", 2); + if (!model_pieces[0]) { + error_report("Invalid/empty CPU model name"); + exit(1); + } + + oc = cpu_class_by_name(TYPE_POWERPC_CPU, model_pieces[0]); + if (oc == NULL) { + error_report("Unable to find CPU definition: %s", model_pieces[0]); + exit(1); + } + + typename = object_class_get_name(oc); + cc = CPU_CLASS(oc); + cc->parse_features(typename, model_pieces[1], &error_fatal); + g_strfreev(model_pieces); +} diff --git a/hw/ppc/ppc440_bamboo.c b/hw/ppc/ppc440_bamboo.c index 7f22433c8e91..709a779cba7e 100644 --- a/hw/ppc/ppc440_bamboo.c +++ b/hw/ppc/ppc440_bamboo.c @@ -186,6 +186,7 @@ static void bamboo_init(MachineState *machine) if (machine->cpu_model == NULL) { machine->cpu_model = "440EP"; } + ppc_cpu_parse_features(machine->cpu_model); cpu = ppc_cpu_init(machine->cpu_model); if (cpu == NULL) { fprintf(stderr, "Unable to initialize CPU!\n"); diff --git a/hw/ppc/ppc4xx_devs.c b/hw/ppc/ppc4xx_devs.c index d48b61f04910..8cbe50361e86 100644 --- a/hw/ppc/ppc4xx_devs.c +++ b/hw/ppc/ppc4xx_devs.c @@ -56,6 +56,7 @@ PowerPCCPU *ppc4xx_init(const char *cpu_model, CPUPPCState *env; /* init CPUs */ + ppc_cpu_parse_features(cpu_model); cpu = ppc_cpu_init(cpu_model); if (cpu == NULL) { fprintf(stderr, "Unable to find PowerPC %s CPU definition\n", diff --git a/hw/ppc/prep.c b/hw/ppc/prep.c index e62fe643f492..99409a09f0ef 100644 --- a/hw/ppc/prep.c +++ b/hw/ppc/prep.c @@ -508,6 +508,7 @@ static void ppc_prep_init(MachineState *machine) /* init CPUs */ if (machine->cpu_model == NULL) machine->cpu_model = "602"; + ppc_cpu_parse_features(machine->cpu_model); for (i = 0; i < smp_cpus; i++) { cpu = ppc_cpu_init(machine->cpu_model); if (cpu == NULL) { diff --git a/hw/ppc/spapr.c b/hw/ppc/spapr.c index d134eb2f338e..658ccee799c0 100644 --- a/hw/ppc/spapr.c +++ b/hw/ppc/spapr.c @@ -1803,6 +1803,8 @@ static void ppc_spapr_init(MachineState *machine) machine->cpu_model = kvm_enabled() ?
