2023-10-11gdbstub: Replace gdb_regs with an arrayAkihiko Odaki
An array is a more appropriate data structure than a list for gdb_regs since it is initialized only with append operation and read-only after initialization.

2023-10-11hw/core/cpu: Return static value with gdb_arch_name()Akihiko Odaki
All implementations of gdb_arch_name() returns dynamic duplicates of static strings. It's also unlikely that there will be an implementation of gdb_arch_name() that returns a truly dynamic value due to the nature of the function returning a well-known identifiers. Qualify the value gdb_arch_name() with const and make all of its implementations return static strings.

hvf_get_supported_cpuid() is only defined for x86 targets (in target/i386/hvf/x86_cpuid.c). Its declaration is pointless on all other targets. All the calls to it in target/i386/cpu.c are guarded by a call on hvf_enabled(), so are elided when HVF is not built in. Therefore we can remove the unnecessary function stub.

2023-10-06q800: add alias for MacOS toolbox ROM at 0x40000000Mark Cave-Ayland
According to the Apple Quadra 800 Developer Note document, the Quadra 800 ROM consists of 2 ROM code sections based at offsets 0x0 and 0x800000. A/UX attempts to access the toolbox ROM at the lower offset during startup, so provide a memory alias to allow the access to succeed.

2023-10-06q800: add ESCC alias at 0xc000Mark Cave-Ayland
Tests on real Q800 hardware show that the ESCC is addressable at multiple locations within the ESCC memory region - at least 0xc000, 0xc020 (as expected by the MacOS toolbox ROM) and 0xc040. All released NetBSD kernels before 10 use the 0xc000 address which causes a fatal error when running the MacOS booter. Add a single memory region alias at 0xc000 to enable NetBSD kernels to start booting under QEMU.

2023-10-06mac_via: work around underflow in TimeDBRA timing loop in SETUPTIMEKMark Cave-Ayland
The MacOS toolbox ROM calculates the number of branches that can be executed per millisecond as part of its timer calibration. Since modern hosts are considerably quicker than original hardware, the negative counter reaches zero before the calibration completes leading to division by zero later in CALCULATESLOD. Instead of trying to fudge the timing loop (which won't work for TimeDBRA/TimeSCCDB anyhow), use the pattern of access to the VIA1 registers to detect when SETUPTIMEK has finished executing and write some well-known good timer values to TimeDBRA and TimeSCCDB taken from real hardware with a suitable scaling factor.

2023-10-06asc: generate silence if FIFO empty but engine still runningMark Cave-Ayland
MacOS (un)helpfully leaves the FIFO engine running even when all the samples have been written to the hardware, and expects the FIFO status flags and IRQ to be updated continuously. There is an additional problem in that not all audio backends guarantee an all-zero output when there is no FIFO data available, in particular the Windows dsound backend which re-uses its internal circular buffer causing the last played sound to loop indefinitely. Whilst this is effectively a bug in the Windows dsound backend, work around it for now using a simple heuristic: if the FIFO remains empty for half a cycle (~23ms) then continuously fill the generated buffer with empty silence.

Still, until a later patch lets the client negotiate extended headers, the code added here should not be reached.

2023-10-04vhost-user: add shared_object msgAlbert Esteve
Add three new vhost-user protocol `VHOST_USER_BACKEND_SHARED_OBJECT_* messages`. These new messages are sent from vhost-user back-ends to interact with the virtio-dmabuf table in order to add or remove themselves as virtio exporters, or lookup for virtio dma-buf shared objects. The action taken in the front-end depends on the type stored in the virtio shared object hash table. When the table holds a pointer to a vhost backend for a given UUID, the front-end sends a VHOST_USER_GET_SHARED_OBJECT to the backend holding the shared object. The messages can only be sent after successfully negotiating a new VHOST_USER_PROTOCOL_F_SHARED_OBJECT vhost-user protocol feature bit. Finally, refactor code to send response message so that all common parts both for the common REPLY_ACK case, and other data responses, can call it and avoid code repetition.

2023-10-04hw/i386/pc: improve physical address space bound check for 32-bit x86 systemsAni Sinha
32-bit x86 systems do not have a reserved memory for hole64. On those 32-bit systems without PSE36 or PAE CPU features, hotplugging memory devices are not supported by QEMU as QEMU always places hotplugged memory above 4 GiB boundary which is beyond the physical address space of the processor. Linux guests also does not support memory hotplug on those systems. Please see Linux kernel commit b59d02ed08690 ("mm/memory_hotplug: disable the functionality for 32b") for more details. Therefore, the maximum limit of the guest physical address in the absence of additional memory devices effectively coincides with the end of "above 4G memory space" region for 32-bit x86 without PAE/PSE36. When users configure additional memory devices, after properly accounting for the additional device memory region to find the maximum value of the guest physical address, the address will be outside the range of the processor's physical address space. This change adds improvements to take above into consideration. For example, previously this was allowed: $ ./qemu-system-x86_64 -cpu pentium -m size=10G With this change now it is no longer allowed: $ ./qemu-system-x86_64 -cpu pentium -m size=10G qemu-system-x86_64: Address space limit 0xffffffff < 0x2bfffffff phys-bits too low (32) However, the following are allowed since on both cases physical address space of the processor is 36 bits: $ ./qemu-system-x86_64 -cpu pentium2 -m size=10G $ ./qemu-system-x86_64 -cpu pentium,pse36=on -m size=10G For 32-bit, without PAE/PSE36, hotplugging additional memory is no longer allowed. $ ./qemu-system-i386 -m size=1G,maxmem=3G,slots=2 qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32) $ ./qemu-system-i386 -machine q35 -m size=1G,maxmem=3G,slots=2 qemu-system-i386: Address space limit 0xffffffff < 0x1ffffffff phys-bits too low (32) A new compatibility flag is introduced to make sure pc_max_used_gpa() keeps returning the old value for machines 8.1 and older. Therefore, the above is still allowed for older machine types in order to support compatibility. Hence, the following still works: $ ./qemu-system-i386 -machine pc-i440fx-8.1 -m size=1G,maxmem=3G,slots=2 $ ./qemu-system-i386 -machine pc-q35-8.1 -m size=1G,maxmem=3G,slots=2 Further, following is also allowed as with PSE36, the processor has 36-bit address space: $ ./qemu-system-i386 -cpu 486,pse36=on -m size=1G,maxmem=3G,slots=2 After calling CPUID with EAX=0x80000001, all AMD64 compliant processors have the longmode-capable-bit turned on in the extended feature flags (bit 29) in EDX. The absence of CPUID longmode can be used to differentiate between 32-bit and 64-bit processors and is the recommended approach. QEMU takes this approach elsewhere (for example, please see x86_cpu_realizefn()), With this change, pc_max_used_gpa() also uses the same method to detect 32-bit processors. Unit tests are modified to not run 32-bit x86 tests that use memory hotplug.

2023-10-04hw/acpi/cpu: Have build_cpus_aml() take a build_madt_cpu_fn callbackBernhard Beschow
build_cpus_aml() is architecture independent but needs to create architecture- specific CPU AML. So far this was achieved by using a virtual method from TYPE_ACPI_DEVICE_IF. However, build_cpus_aml() would resolve this interface from global (!) state. This makes it quite incomprehensible where this interface comes from (TYPE_PIIX4_PM?, TYPE_ICH9_LPC_DEVICE?, TYPE_ACPI_GED_X86?) an can lead to crashes when the generic code is ported to new architectures. So far, build_cpus_aml() is only called in architecture-specific code -- and only in x86. We can therefore simply pass pc_madt_cpu_entry() as callback to build_cpus_aml(). This is the same callback that would be used through TYPE_ACPI_DEVICE_IF.
