2023-10-12hw/misc/sifive_test.c: replace exit calls with proper shutdownClément Chigot
This replaces the exit calls by shutdown requests, ensuring a proper cleanup of Qemu. Otherwise, some connections like gdb could be broken before its final packet ("Wxx") is being sent. This part, being done inside qemu_cleanup function, can be reached only when the main loop exits after a shutdown request.

2023-10-12target/riscv: move KVM only files to kvm subdirDaniel Henrique Barboza
Move the files to a 'kvm' dir to promote more code separation between accelerators and making our lives easier supporting build options such as --disable-tcg. Rename kvm.c to kvm-cpu.c to keep it in line with its TCG counterpart.

2023-10-10hw/audio/es1370: trace lost interruptsVolker Rümelin
It turns out that there are drivers which assume that interrupts can't be lost. E.g. the AROS sb128 driver is such a driver. Add a lost interrupt tracepoint to debug this kind of issues.

2023-10-10hw/audio/es1370: reset current sample counterVolker Rümelin
Reset the current sample counter when writing the Channel Sample Count Register. The Linux ens1370 driver and the AROS sb128 driver expect the current sample counter counts down from sample count to 0 after a write to the Channel Sample Count Register. Currently the current sample counter starts from 0 after a reset or the last count when the counter was stopped. The current sample counter is used to raise an interrupt whenever a complete buffer was transferred. When the counter starts with a value lower than the reload value, the interrupt triggeres before the buffer was completly transferred. This may lead to corrupted audio streams.

2023-10-06mac_via: always clear ADB interrupt when switching to A/UX modeMark Cave-Ayland
When the NetBSD kernel initialises it can leave the ADB interrupt asserted depending upon where in the ADB poll cycle the MacOS ADB interrupt handler is when the NetBSD kernel disables interrupts. The NetBSD ADB driver uses the ADB interrupt state to determine if the ADB is busy and refuses to send ADB commands unless it is clear. To ensure that this doesn't happen, always clear the ADB interrupt when switching to A/UX mode to ensure that the bus enumeration always occurs.

NetBSD assumes it can send its first ADB command after sending the ADB_BUSRESET command in ADB_STATE_NEW without changing the state back to ADB_STATE_IDLE first as detailed in the ADB protocol. Add a workaround to detect this condition at the start of ADB enumeration and send the next command written to SR after a ADB_BUSRESET onto the bus regardless, even if we don't detect a state transition to ADB_STATE_NEW.

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.

2023-10-05vfio/pci: enable MSI-X in interrupt restoring on dynamic allocationJing Liu
During migration restoring, vfio_enable_vectors() is called to restore enabling MSI-X interrupts for assigned devices. It sets the range from 0 to nr_vectors to kernel to enable MSI-X and the vectors unmasked in guest. During the MSI-X enabling, all the vectors within the range are allocated according to the VFIO_DEVICE_SET_IRQS ioctl. When dynamic MSI-X allocation is supported, we only want the guest unmasked vectors being allocated and enabled. Use vector 0 with an invalid fd to get MSI-X enabled, after that, all the vectors can be allocated in need.

2023-10-05vfio/pci: use an invalid fd to enable MSI-XJing Liu
Guests typically enable MSI-X with all of the vectors masked in the MSI-X vector table. To match the guest state of device, QEMU enables MSI-X by enabling vector 0 with userspace triggering and immediately release. However the release function actually does not release it due to already using userspace mode. It is no need to enable triggering on host and rely on the mask bit to avoid spurious interrupts. Use an invalid fd (i.e. fd = -1) is enough to get MSI-X enabled. After dynamic MSI-X allocation is supported, the interrupt restoring also need use such way to enable MSI-X, therefore, create a function for that.

2023-10-05vfio/pci: enable vector on dynamic MSI-X allocationJing Liu
The vector_use callback is used to enable vector that is unmasked in guest. The kernel used to only support static MSI-X allocation. When allocating a new interrupt using "static MSI-X allocation" kernels, QEMU first disables all previously allocated vectors and then re-allocates all including the new one. The nr_vectors of VFIOPCIDevice indicates that all vectors from 0 to nr_vectors are allocated (and may be enabled), which is used to loop all the possibly used vectors when e.g., disabling MSI-X interrupts. Extend the vector_use function to support dynamic MSI-X allocation when host supports the capability. QEMU therefore can individually allocate and enable a new interrupt without affecting others or causing interrupts lost during runtime. Utilize nr_vectors to calculate the upper bound of enabled vectors in dynamic MSI-X allocation mode since looping all msix_entries_nr is not efficient and unnecessary.
