From 38c87d1469539d2b5224d298db85b0fd43d8bb0c Mon Sep 17 00:00:00 2001 From: Miroslav Rezanina Date: Fri, 19 Oct 2018 12:53:31 +0200 Subject: Add aarch64 machine types Adding changes to add RHEL machine types for aarch64 architecture. Signed-off-by: Miroslav Rezanina --- Rebase notes (210623): - Use CONFIG_TPM check when using TPM structures Rebase notes (6.1.0 rc0): - Add support for default_bus_bypass_iommu Merged patches (6.1.0 rc1): - ea4c0b32d9 arm/virt: Register highmem and gic-version as class properties - 895e1fa86a hw/arm/virt: Add 8.5 and 9.0 machine types and remove older ones --- hw/arm/virt.c | 210 +++++++++++++++++++++++++++++++++++++++++- include/hw/arm/virt.h | 8 ++ 2 files changed, 217 insertions(+), 1 deletion(-) diff --git a/hw/arm/virt.c b/hw/arm/virt.c index cd1a2d985d..3c8e6de36d 100644 --- a/hw/arm/virt.c +++ b/hw/arm/virt.c @@ -78,6 +78,7 @@ #include "hw/char/pl011.h" #include "qemu/guest-random.h" +#if 0 /* Disabled for Red Hat Enterprise Linux */ #define DEFINE_VIRT_MACHINE_LATEST(major, minor, latest) \ static void virt_##major##_##minor##_class_init(ObjectClass *oc, \ void *data) \ @@ -104,7 +105,48 @@ DEFINE_VIRT_MACHINE_LATEST(major, minor, true) #define DEFINE_VIRT_MACHINE(major, minor) \ DEFINE_VIRT_MACHINE_LATEST(major, minor, false) - +#endif /* disabled for RHEL */ + +#define DEFINE_RHEL_MACHINE_LATEST(m, n, s, latest) \ + static void rhel##m##n##s##_virt_class_init(ObjectClass *oc, \ + void *data) \ + { \ + MachineClass *mc = MACHINE_CLASS(oc); \ + rhel##m##n##s##_virt_options(mc); \ + mc->desc = "RHEL " # m "." # n "." # s " ARM Virtual Machine"; \ + if (latest) { \ + mc->alias = "virt"; \ + mc->is_default = 1; \ + } \ + } \ + static const TypeInfo rhel##m##n##s##_machvirt_info = { \ + .name = MACHINE_TYPE_NAME("virt-rhel" # m "." # n "." # s), \ + .parent = TYPE_RHEL_MACHINE, \ + .class_init = rhel##m##n##s##_virt_class_init, \ + }; \ + static void rhel##m##n##s##_machvirt_init(void) \ + { \ + type_register_static(&rhel##m##n##s##_machvirt_info); \ + } \ + type_init(rhel##m##n##s##_machvirt_init); + +#define DEFINE_RHEL_MACHINE_AS_LATEST(major, minor, subminor) \ + DEFINE_RHEL_MACHINE_LATEST(major, minor, subminor, true) +#define DEFINE_RHEL_MACHINE(major, minor, subminor) \ + DEFINE_RHEL_MACHINE_LATEST(major, minor, subminor, false) + +/* This variable is for changes to properties that are RHEL specific, + * different to the current upstream and to be applied to the latest + * machine type. + */ +GlobalProperty arm_rhel_compat[] = { + { + .driver = "virtio-net-pci", + .property = "romfile", + .value = "", + }, +}; +const size_t arm_rhel_compat_len = G_N_ELEMENTS(arm_rhel_compat); /* Number of external interrupt lines to configure the GIC with */ #define NUM_IRQS 256 @@ -2117,6 +2159,7 @@ static void machvirt_init(MachineState *machine) qemu_add_machine_init_done_notifier(&vms->machine_done); } +#if 0 /* Disabled for Red Hat Enterprise Linux */ static bool virt_get_secure(Object *obj, Error **errp) { VirtMachineState *vms = VIRT_MACHINE(obj); @@ -2144,6 +2187,7 @@ static void virt_set_virt(Object *obj, bool value, Error **errp) vms->virt = value; } +#endif /* disabled for RHEL */ static bool virt_get_highmem(Object *obj, Error **errp) { @@ -2241,6 +2285,7 @@ static void virt_set_acpi(Object *obj, Visitor *v, const char *name, visit_type_OnOffAuto(v, name, &vms->acpi, errp); } +#if 0 /* Disabled for Red Hat Enterprise Linux */ static bool virt_get_ras(Object *obj, Error **errp) { VirtMachineState *vms = VIRT_MACHINE(obj); @@ -2268,6 +2313,7 @@ static void virt_set_mte(Object *obj, bool value, Error **errp) vms->mte = value; } +#endif /* disabled for RHEL */ static char *virt_get_gic_version(Object *obj, Error **errp) { @@ -2603,6 +2649,7 @@ static int virt_kvm_type(MachineState *ms, const char *type_str) return fixed_ipa ?
