* hw/acpi/microvm: turn on 8042 bit in FADT boot architecture flags if presentAni Sinha2022-03-071-0/+6
| | | | | | | | | | | | | | | | | | The second bit of IAPC_BOOT_ARCH in FADT table indicates the presence of keyboard controller implemented as 8042 or equivalent micro controller. This change enables this flag for microvms if such a device exists (for example, when added explicitly from the QEMU commandline). Change 654701e292d98b308b0 ("hw/acpi: add indication for i8042 in IA-PC boot flags of the FADT table") enabled this flag for i386 q35 based machines. The reason for doing the same for micro-vms is to make sure we provide the correct tables to the guest OS uniformly in all cases when an i8042 device is present. When this bit is not enabled, guest OSes has to find other indirect methods to detect the device which we would like to avoid.

* hw/acpi: add indication for i8042 in IA-PC boot flags of the FADT tableLiav Albani2022-03-061-0/+8
| | | | | | | | | | | | | | | | | | This can allow the guest OS to determine more easily if i8042 controller is present in the system or not, so it doesn't need to do probing of the controller, but just initialize it immediately, before enumerating the ACPI AML namespace. The 8042 bit in IAPC_BOOT_ARCH was introduced from ACPI spec v2 (FADT revision 2 and above). Therefore, in this change, we only enable this bit for x86/q35 machine types since x86/i440fx machines use FADT ACPI table with revision 1.

* pc: add option to disable PS/2 mouse/keyboardJoelle van Dyne2022-03-061-2/+26
| | | | | | | | | | | | | | | | 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. This introduces a new machine property to inhibit the creation of the i8042 PS/2 controller.

* intel_iommu: support snoop controlJason Wang2022-03-062-1/+14
| | | | | | | | | | | | | | | | | | | | SC is required for some kernel features like vhost-vDPA. So this patch implements basic SC feature. The idea is pretty simple, for software emulated DMA it would be always coherent. In this case we can simple advertise ECAP_SC bit. For VFIO and vhost, thing will be more much complicated, so this patch simply fail the IOMMU notifier registration. In the future, we may want to have a dedicated notifiers flag or similar mechanism to demonstrate the coherency so VFIO could advertise that if it has VFIO_DMA_CC_IOMMU, for vhost kernel backend we don't need that since it's a software backend.

For example, this may happen when using emulated NVME and the guest submits a large scatter-gather write. At this point, the entry map be remapped causing QEMU to write the wrong data or crash (since remap is not atomic). Avoid this overflow by increasing the lock field to a uint32_t and also detect it and abort rather than continuing regardless.

|/ | | | | | | | | | | | | | | | | | | commit f37f29d31488 "xen: slightly simplify bufioreq handling" hard coded setting req.count = 1 during initial field setup before the main loop. This missed a subtlety that an early exit from the loop when there are no ioreqs to process, would have req.count == 0 for the return value. handle_buffered_io() would then remove state->buffered_io_timer. Instead handle_buffered_iopage() is basically always returning true and handle_buffered_io() always re-setting the timer. Restore the disabling of the timer by introducing a new handled_ioreq boolean and use as the return value. The named variable will more clearly show the intent of the code.

Fix issue by handling oem_id consistently and make acpi_get_slic_oem() return NULL terminated strings. PS: After [1] refactoring, oem_id semantics became inconsistent, where NULL terminated string was coming from machine and old way pointer into byte array coming from -acpitable option. That used to work since build_header() wasn't expecting NULL terminated string and blindly copied the 1st 6 bytes only. However commit [2] broke that by replacing build_header() with acpi_table_begin(), which was expecting NULL terminated string and was checking oem_id size. 1) 602b45820 ("acpi: Permit OEM ID and OEM table ID fields to be changed") 2) Fixes: 4b56e1e4eb08 ("acpi: build_fadt: use acpi_table_begin()/acpi_table_end() instead of build_header()") Resolves: https://gitlab.com/qemu-project/qemu/-/issues/786 Signed-off-by: Igor Mammedov <imammedo@redhat.com> Message-Id: <20211227193120.1084176-2-imammedo@redhat.com> Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Tested-by: Denis Lisov <dennis.lissov@gmail.com> Tested-by: Alexander Tsoy <alexander@tsoy.me> Cc: qemu-stable@nongnu.org Reviewed-by: Michael S.

| | | | | | | | | | | | | | | | | | | | | | | 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.

* smbios: Rename SMBIOS_ENTRY_POINT_* enumsEduardo Habkost2022-01-072-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | Rename the enums to match the naming style used by QAPI, and to use "32" and "64" instead of "20" and "31". This will allow us to more easily move the enum to the QAPI schema later. About the naming choice: "SMBIOS 2.1 entry point"/"SMBIOS 3.0 entry point" and "32-bit entry point"/"64-bit entry point" are synonymous in the SMBIOS specification. However, the phrases "32-bit entry point" and "64-bit entry point" are used more often. The new names also avoid confusion between the entry point format and the actual SMBIOS version reported in the entry point structure. For example: currently the 32-bit entry point actually report SMBIOS 2.8 support, not 2.1. Based on portions of a patch submitted by Daniel P. Berrangé.

This was the first approach which led to regression [1-2], as I/O space for a port is allocated only when it is hot-pluggable, which is determined by HPC bit. * Leave the HPC bit on and disable PCIe Native Hot-plug in _OSC method. This removes the (future) ability of hot-plugging switches with PCIe Native hotplug since ACPI PCI Hot-plug only works with cold-plugged bridges. If the user wants to explicitely use this feature, they can disable ACPI PCI Hot-plug with: --global ICH9-LPC.acpi-pci-hotplug-with-bridge-support=off Change the bit in _OSC method so that the OS selects ACPI PCI Hot-plug instead of PCIe Native.

However that never worked since slot is wired to ACPI hotplug controller. Another non-intended usecase: disable native hotplug on slot when APCI based hotplug is disabled, which works but slot has 'hotplug' property for this taks. It should be relatively safe to rename it to experimental as no users should exist for it and given that the property is broken we don't really want to leave it around for much longer lest users start using it.

* | sgx: Reset the vEPC regions during VM rebootYang Zhong2021-11-101-0/+50
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For bare-metal SGX on real hardware, the hardware provides guarantees SGX state at reboot. For instance, all pages start out uninitialized. The vepc driver provides a similar guarantee today for freshly-opened vepc instances, but guests such as Windows expect all pages to be in uninitialized state on startup, including after every guest reboot. Qemu can invoke the ioctl to bring its vEPC pages back to uninitialized state. There is a possibility that some pages fail to be removed if they are SECS pages, and the child and SECS pages could be in separate vEPC regions. Therefore, the ioctl returns the number of EREMOVE failures, telling Qemu to try the ioctl again after it's done with all vEPC regions.
