Richard Henderson	5fcabe628b	include/hw/qdev-properties: Remove DEFINE_PROP_END_OF_LIST Now that all of the Property arrays are counted, we can remove the terminator object from each array. Update the assertions in device_class_set_props to match. With struct Property being 88 bytes, this was a rather large form of terminator. Saves 30k from qemu-system-aarch64.

Yang Zhong	1105812382	numa: Enable numa for SGX EPC sections The basic SGX did not enable numa for SGX EPC sections, which result in all EPC sections located in numa node 0. This patch enable SGX numa function in the guest and the EPC section can work with RAM as one numa node. The Guest kernel related log: [ 0.009981] ACPI: SRAT: Node 0 PXM 0 [mem 0x180000000-0x183ffffff] [ 0.009982] ACPI: SRAT: Node 1 PXM 1 [mem 0x184000000-0x185bfffff] The SRAT table can normally show SGX EPC sections menory info in different numa nodes.

Yang Zhong	a7c565a941	sgx-epc: Add the fill_device_info() callback support Since there is no fill_device_info() callback support, and when we execute "info memory-devices" command in the monitor, the segfault will be found. This patch will add this callback support and "info memory-devices" will show sgx epc memory exposed to guest. The result as below: qemu) info memory-devices Memory device [sgx-epc]: "" memaddr: 0x180000000 size: 29360128 memdev: /objects/mem1 Memory device [sgx-epc]: "" memaddr: 0x181c00000 size: 10485760 memdev: /objects/mem2 Signed-off-by: Yang Zhong <yang.zhong@intel.com> Message-Id: <20210719112136.57018-33-yang.zhong@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	5 years ago
Sean Christopherson	dfce81f1b9	vl: Add sgx compound properties to expose SGX EPC sections to guest Because SGX EPC is enumerated through CPUID, EPC "devices" need to be realized prior to realizing the vCPUs themselves, i.e. long before generic devices are parsed and realized. From a virtualization perspective, the CPUID aspect also means that EPC sections cannot be hotplugged without paravirtualizing the guest kernel (hardware does not support hotplugging as EPC sections must be locked down during pre-boot to provide EPC's security properties). So even though EPC sections could be realized through the generic -devices command, they need to be created much earlier for them to actually be usable by the guest. Place all EPC sections in a contiguous block, somewhat arbitrarily starting after RAM above 4g. Ensuring EPC is in a contiguous region simplifies calculations, e.g. device memory base, PCI hole, etc..., allows dynamic calculation of the total EPC size, e.g. exposing EPC to guests does not require -maxmem, and last but not least allows all of EPC to be enumerated in a single ACPI entry, which is expected by some kernels, e.g. Windows 7 and 8. The new compound properties command for sgx like below: ...... -object memory-backend-epc,id=mem1,size=28M,prealloc=on \ -object memory-backend-epc,id=mem2,size=10M \ -M sgx-epc.0.memdev=mem1,sgx-epc.1.memdev=mem2 Signed-off-by: Sean Christopherson <sean.j.christopherson@intel.com> Signed-off-by: Yang Zhong <yang.zhong@intel.com> Message-Id: <20210719112136.57018-6-yang.zhong@intel.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>	5 years ago
Sean Christopherson	80509c5557	i386: Add 'sgx-epc' device to expose EPC sections to guest SGX EPC is enumerated through CPUID, i.e. EPC "devices" need to be realized prior to realizing the vCPUs themselves, which occurs long before generic devices are parsed and realized. Because of this, do not allow 'sgx-epc' devices to be instantiated after vCPUS have been created. The 'sgx-epc' device is essentially a placholder at this time, it will be fully implemented in a future patch along with a dedicated command to create 'sgx-epc' devices.
