2022-07-26i386/pc: restrict AMD only enforcing of 1Tb hole to new machine typeJoao Martins
The added enforcing is only relevant in the case of AMD where the range right before the 1TB is restricted and cannot be DMA mapped by the kernel consequently leading to IOMMU INVALID_DEVICE_REQUEST or possibly other kinds of IOMMU events in the AMD IOMMU. Although, there's a case where it may make sense to disable the IOVA relocation/validation when migrating from a non-amd-1tb-aware qemu to one that supports it. Relocating RAM regions to after the 1Tb hole has consequences for guest ABI because we are changing the memory mapping, so make sure that only new machine enforce but not older ones.

2022-07-22hw/i386: pass RNG seed via setup_data entryJason A. Donenfeld
Tiny machines optimized for fast boot time generally don't use EFI, which means a random seed has to be supplied some other way. For this purpose, Linux (≥5.20) supports passing a seed in the setup_data table with SETUP_RNG_SEED, specially intended for hypervisors, kexec, and specialized bootloaders. The linked commit shows the upstream kernel implementation. At Paolo's request, we don't pass these to versioned machine types ≤7.0.

2022-03-06pc: add option to disable PS/2 mouse/keyboardJoelle van Dyne
On some older software like Windows 7 installer, having both a PS/2 mouse and USB mouse results in only one device working property (which might be a different device each boot). While the workaround to not use a USB mouse with such software is valid, it creates an inconsistent experience if the user wishes to always use a USB mouse.

The i440fx and Q35 machine types are both hardcoded to use the legacy SMBIOS 2.1 (32-bit) entry point. This is a sensible conservative choice because SeaBIOS only supports SMBIOS 2.1 EDK2, however, can also support SMBIOS 3.0 (64-bit) entry points, and QEMU already uses this on the ARM virt machine type. This adds a property to allow the choice of SMBIOS entry point versions For example to opt in to 64-bit SMBIOS entry point: $QEMU -machine q35,smbios-entry-point-type=64 Based on a patch submitted by Daniel Berrangé.

2021-11-01hw/i386/pc: Move IOMMU singleton into PCMachineStateJean-Philippe Brucker
We're about to support a third vIOMMU for x86, virtio-iommu which doesn't inherit X86IOMMUState. Move the IOMMU singleton into PCMachineState, so it can be shared between all three vIOMMUs. The x86_iommu_get_default() helper is still needed by KVM and IOAPIC to fetch the default IRQ-remapping IOMMU. Since virtio-iommu doesn't support IRQ remapping, this interface doesn't need to change for the moment. We could later replace X86IOMMUState with an "IRQ remapping IOMMU" interface if necessary.

2021-09-30i386: Update SGX CPUID info according to hardware/KVM/user inputSean Christopherson
Expose SGX to the guest if and only if KVM is enabled and supports virtualization of SGX. While the majority of ENCLS can be emulated to some degree, because SGX uses a hardware-based root of trust, the attestation aspects of SGX cannot be emulated in software, i.e. ultimately emulation will fail as software cannot generate a valid quote/report. The complexity of partially emulating SGX in Qemu far outweighs the value added, e.g. an SGX specific simulator for userspace applications can emulate SGX for development and testing purposes. Note, access to the PROVISIONKEY is not yet advertised to the guest as KVM blocks access to the PROVISIONKEY by default and requires userspace to provide additional credentials (via ioctl()) to expose PROVISIONKEY.

2021-09-30vl: Add sgx compound properties to expose SGX EPC sections to guestSean Christopherson
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>

2021-02-16pc: add parser for OVMF reset blockJames Bottomley
OVMF is developing a mechanism for depositing a GUIDed table just below the known location of the reset vector. The table goes backwards in memory so all entries are of the form <data>|len|<GUID> Where <data> is arbtrary size and type, <len> is a uint16_t and describes the entire length of the entry from the beginning of the data to the end of the guid. The foot of the table is of this form and <len> for this case describes the entire size of the table. The table foot GUID is defined by OVMF as 96b582de-1fb2-45f7-baea-a366c55a082d and if the table is present this GUID is just below the reset vector, 48 bytes before the end of the firmware file. Add a parser for the ovmf reset block which takes a copy of the block, if the table foot guid is found, minus the footer and a function for later traversal to return the data area of any specified GUIDs.

2021-02-05acpi: Permit OEM ID and OEM table ID fields to be changedMarian Postevca
Qemu's ACPI table generation sets the fields OEM ID and OEM table ID to "BOCHS " and "BXPCxxxx" where "xxxx" is replaced by the ACPI table name. Some games like Red Dead Redemption 2 seem to check the ACPI OEM ID and OEM table ID for the strings "BOCHS" and "BXPC" and if they are found, the game crashes(this may be an intentional detection mechanism to prevent playing the game in a virtualized environment). This patch allows you to override these default values. The feature can be used in this manner: qemu -machine oem-id=ABCDEF,oem-table-id=GHIJKLMN The oem-id string can be up to 6 bytes in size, and the oem-table-id string can be up to 8 bytes in size. If the string are smaller than their respective sizes they will be padded with space. If either of these parameters is not set, the current default values will be used for the one missing. Note that the the OEM Table ID field will not be extended with the name of the table, but will use either the default name or the user provided one. This does not affect the -acpitable option (for user-defined ACPI tables), which has precedence over -machine option.

2020-09-30target/i386: always create kvmclock deviceVitaly Kuznetsov
QEMU's kvmclock device is only created when KVM PV feature bits for kvmclock (KVM_FEATURE_CLOCKSOURCE/KVM_FEATURE_CLOCKSOURCE2) are exposed to the guest. With 'kvm=off' cpu flag the device is not created and we don't call KVM_GET_CLOCK/KVM_SET_CLOCK upon migration. It was reported that without these call at least Hyper-V TSC page clocksouce (which can be enabled independently) gets broken after migration. Switch to creating kvmclock QEMU device unconditionally, it seems to always make sense to call KVM_GET_CLOCK/KVM_SET_CLOCK on migration. Use KVM_CAP_ADJUST_CLOCK check instead of CPUID feature bits.

2020-07-10xen: cleanup unrealized flash devicesPaul Durrant
The generic pc_machine_initfn() calls pc_system_flash_create() which creates 'system.flash0' and 'system.flash1' devices. These devices are then realized by pc_system_flash_map() which is called from pc_system_firmware_init() which itself is called via pc_memory_init(). The latter however is not called when xen_enable() is true and hence the following assertion fails: qemu-system-i386: hw/core/qdev.c:439: qdev_assert_realized_properly: Assertion `dev->realized' failed These flash devices are unneeded when using Xen so this patch avoids the assertion by simply removing them using pc_system_flash_cleanup_unused().
