2024-02-27hw/i386/pc_{piix, q35}: Eliminate local pci_bus/pci_host variablesBernhard Beschow2-17/+13
There is no advantage in having these local variables which 1/ needlessly have different identifiers in both machines and 2/ which are redundant to pcms->bus which is almost as short.

2024-02-22hw/i386/pc: Do pc_cmos_init_late() from pc_machine_done()Peter Maydell1-23/+16
In the i386 PC machine, we want to run the pc_cmos_init_late() function only once the IDE and floppy drive devices have been set up. We currently do this using qemu_register_reset(), and then have the function call qemu_unregister_reset() on itself, so it runs exactly once. This was an expedient way to do it back in 2010 when we first added this (in commit c0897e0cb94e8), but now we have a more obvious point to do "machine initialization that has to happen after generic device init": the machine-init-done hook. Do the pc_cmos_init_late() work from our existing PC machine init done hook function, so we can drop the use of qemu_register_reset() and qemu_unregister_reset(). Because the pointers to the devices we need (the IDE buses and the RTC) are now all in the machine state, we don't need the pc_cmos_init_late_arg struct and can just pass the PCMachineState pointer.

2024-02-14hw/i386: Fix _STA return value for ACPI0017Jonathan Cameron1-1/+1
Found whilst testing a series for the linux kernel that actually bothers to check if enabled is set. 0xB is the option used for vast majority of DSDT entries in QEMU. It is a little odd for a device that doesn't really exist and is simply a hook to tell the OS there is a CEDT table but 0xB seems a reasonable choice and avoids need to special case this device in the OS. Means: * Device present. * Device enabled and decoding it's resources. * Not shown in UI * Functioning properly * No battery (on this device!)

2024-02-14hw/i386/x86: Fix PIC interrupt handling if APIC is globally disabledBernhard Beschow1-2/+2
QEMU populates the apic_state attribute of x86 CPUs if supported by real hardware or if SMP is active. When handling interrupts, it just checks whether apic_state is populated to route the interrupt to the PIC or to the APIC. However, chapter 10.4.3 of [1] requires that: When IA32_APIC_BASE[11] is 0, the processor is functionally equivalent to an IA-32 processor without an on-chip APIC. This means that when apic_state is populated, QEMU needs to check for the MSR_IA32_APICBASE_ENABLE flag in addition. Implement this which fixes some real-world BIOSes.

2024-02-14amd_iommu: report x2APIC support to the operating systemBui Quang Minh5-46/+133
This commit adds XTSup configuration to let user choose to whether enable this feature or not. When XTSup is enabled, additional bytes in IRTE with enabled guest virtual VAPIC are used to support 32-bit destination id. Additionally, this commit exports IVHD type 0x11 besides the old IVHD type 0x10 in ACPI table. IVHD type 0x10 does not report full set of IOMMU features only the legacy ones, so operating system (e.g. Linux) may only detects x2APIC support if IVHD type 0x11 is available. The IVHD type 0x10 is kept so that old operating system that only parses type 0x10 can detect the IOMMU device. Besides, an amd_iommu-stub.c file is created to provide the definition for amdvi_extended_feature_register when CONFIG_AMD_IOMMU=n. This function is used by acpi-build.c to get the extended feature register value for building the ACPI table. When CONFIG_AMD_IOMMU=y, this function is defined in amd_iommu.c.

When instantiating XenBus itself, for each NIC which is configured with either the model unspecified, or set to to "xen" or "xen-net-device", create a corresponding xen-net-device for it. Now we can revert the previous more hackish version which relied on the platform code explicitly registering the NICs on its own XenBus, having returned the BusState* from xen_bus_init() itself. This also fixes the setup for Xen PV guests, which was previously broken in various ways and never actually managed to peer with the netdev.

2024-01-19hw/i386/pc_piix: Make piix_intx_routing_notifier_xen() more device independentBernhard Beschow1-6/+3
This is a follow-up on commit 89965db43cce "hw/isa/piix3: Avoid Xen-specific variant of piix3_write_config()" which introduced piix_intx_routing_notifier_xen(). This function is implemented in board code but accesses the PCI configuration space of the PIIX ISA function to determine the PCI interrupt routes. Avoid this by reusing pci_device_route_intx_to_irq() which makes piix_intx_routing_notifier_xen() more device-agnostic. One remaining improvement would be making piix_intx_routing_notifier_xen() agnostic towards the number of PCI interrupt routes and move it to xen-hvm. This might be useful for possible Q35 Xen efforts but remains a future exercise for now.

2024-01-08system/cpus: rename qemu_mutex_lock_iothread() to bql_lock()Stefan Hajnoczi4-13/+13
The Big QEMU Lock (BQL) has many names and they are confusing. The actual QemuMutex variable is called qemu_global_mutex but it's commonly referred to as the BQL in discussions and some code comments. The locking APIs, however, are called qemu_mutex_lock_iothread() and qemu_mutex_unlock_iothread(). The "iothread" name is historic and comes from when the main thread was split into into KVM vcpu threads and the "iothread" (now called the main loop thread). I have contributed to the confusion myself by introducing a separate --object iothread, a separate concept unrelated to the BQL. The "iothread" name is no longer appropriate for the BQL. Rename the locking APIs to: - void bql_lock(void) - void bql_unlock(void) - bool bql_locked(void) There are more APIs with "iothread" in their names. Subsequent patches will rename them. There are also comments and documentation that will be updated in later patches.
