2023-12-02hw/i386: fix short-circuit logic with non-optimizing buildsDaniel Hoffman
`kvm_enabled()` is compiled down to `0` and short-circuit logic is used to remove references to undefined symbols at the compile stage. Some build configurations with some compilers don't attempt to simplify this logic down in some cases (the pattern appears to be that the literal false must be the first term) and this was causing some builds to emit references to undefined symbols. An example of such a configuration is clang 16.0.6 with the following configure: ./configure --enable-debug --without-default-features --target-list=x86_64-softmmu --enable-tcg-interpreter Signed-off-by: Daniel Hoffman <dhoff749@gmail.com> Message-Id: <20231119203116.3027230-1-dhoff749@gmail.com> Reviewed-by: Michael S.

2023-12-02virtio-sound: add realize() error cleanup pathManos Pitsidianakis
QEMU crashes on exit when a virtio-sound device has failed to realise. Its vmstate field was not cleaned up properly with qemu_del_vm_change_state_handler(). This patch changes the realize() order as 1. Validate the given configuration values (no resources allocated by us either on success or failure) 2. Try AUD_register_card() and return on failure (no resources allocated by us on failure) 3. Initialize vmstate, virtio device, heap allocations and stream parameters at once. If error occurs, goto error_cleanup label which calls virtio_snd_unrealize(). This cleans up all resources made in steps 1-3.

2023-11-28hw/isa/vt82c686: Bring back via_isa_set_irq()BALATON Zoltan
The VIA integrated south bridge chips combine several functions and allow routing their interrupts to any of the ISA IRQs also allowing multiple sources to share the same ISA IRQ. E.g. pegasos2 firmware configures everything to use IRQ 9 but amigaone routes them to separate ISA IRQs so the current simplified routing does not work. Bring back via_isa_set_irq() and change it to take the component that wants to change an IRQ and keep track of interrupt status of each source separately and do the mapping to ISA IRQ within the ISA bridge. This may not handle cases when an ISA IRQ is controlled by devices directly, not going through via_isa_set_irq() such as serial, parallel or keyboard but these IRQs being conventionally fixed are not likely to be change by guests or share with other devices so this does not cause a problem in practice.

2023-11-28qdev: Fix crash in array property getterKevin Wolf
Passing an uninitialised list to visit_start_list() happens to work for the QObject output visitor because it treats the pointer as an opaque value and never dereferences it, but the string output visitor expects a valid list to check if it has more than one element. The existing code crashes with the string output visitor if the uninitialised value is non-NULL. Passing an explicit NULL would fix the crash, but still result in wrong output. Rework get_prop_array() so that it conforms to the expectations that the string output visitor has. This includes building a real list first and using visit_next_list() to iterate it.

2023-11-27hw/dma/xlnx_csu_dma: don't throw guest errors when stopping the SRC DMAFrederic Konrad
UG1087 states for the source channel that: if SIZE is programmed to 0, and the DMA is started, the interrupts DONE and MEM_DONE will be asserted.

2023-11-27hw/ssi/xilinx_spips: fix an out of bound accessFrederic Konrad
The spips, qspips, and zynqmp-qspips share the same realize function (xilinx_spips_realize) and initialize their io memory region with different mmio_ops passed through the class. The size of the memory region is set to the largest area (0x200 bytes for zynqmp-qspips) thus it is possible to write out of s->regs[addr] in xilinx_spips_write for spips and qspips. This fixes that wrong behavior.

2023-11-22riscv: Fix SiFive E CLINT clock frequencyRomán Cárdenas
If you check the manual of SiFive E310 (https://cdn.sparkfun.com/assets/7/f/0/2/7/fe310-g002-manual-v19p05.pdf), you can see in Figure 1 that the CLINT is connected to the real time clock, which also feeds the AON peripheral (they share the same clock). In page 43, the docs also say that the timer registers of the CLINT count ticks from the rtcclk. I am currently playing with bare metal applications both in QEMU and a physical SiFive E310 board and I confirm that the CLINT clock in the physical board runs at 32.768 kHz. In QEMU, the same app produces a completely different outcome, as sometimes a new CLINT interrupt is triggered before finishing other tasks.

2023-11-22hw/riscv/virt.c: do create_fdt() earlier, add finalize_fdt()Daniel Henrique Barboza
Commit 49554856f0 fixed a problem, where TPM devices were not appearing in the FDT, by delaying the FDT creation up until virt_machine_done(). This create a side effect (see gitlab #1925) - devices that need access to the '/chosen' FDT node during realize() stopped working because, at that point, we don't have a FDT. This happens because our FDT creation is monolithic, but it doesn't need to be. We can add the needed FDT components for realize() time and, at the same time, do another FDT round where we account for dynamic sysbus devices. In other words, the problem fixed by 49554856f0 could also be fixed by postponing only create_fdt_sockets() and its dependencies, leaving everything else from create_fdt() to be done during init(). Split the FDT creation in two parts: - create_fdt(), now moved back to virt_machine_init(), will create FDT nodes that doesn't depend on additional (dynamic) devices from the sysbus; - a new finalize_fdt() step is added, where create_fdt_sockets() and friends is executed, accounting for the dynamic sysbus devices that were added during realize(). This will make both use cases happy: TPM devices are still working as intended, and devices such as 'guest-loader' have a FDT to work on during realize().

Allow the VIA IDE controller to switch between both legacy and native modes by calling pci_ide_update_mode() to reconfigure the device whenever PCI_CLASS_PROG is updated. This patch moves the initial setting of PCI_CLASS_PROG from via_ide_realize() to via_ide_reset(), and removes the direct setting of PCI_INTERRUPT_PIN during PCI bus reset since this is now managed by pci_ide_update_mode(). This ensures that the device configuration is always consistent with respect to the currently selected mode.

This function reads the value of the PCI_CLASS_PROG register for PCI IDE controllers and configures the PCI BARs and/or IDE ioports accordingly. In the case where we switch to legacy mode, the PCI BARs are set to return zero (as suggested in the "PCI IDE Controller" specification), the legacy IDE ioports are enabled, and the PCI interrupt pin cleared to indicate legacy IRQ routing. Conversely when we switch to native mode, the legacy IDE ioports are disabled and the PCI interrupt pin set to indicate native IRQ routing. The contents of the PCI BARs are unspecified, but this is not an issue since if a PCI IDE controller has been switched to native mode then its BARs will need to be programmed.

2023-11-21hw/ide/ahci: fix legacy software resetNiklas Cassel
Legacy software contains a standard mechanism for generating a reset to a Serial ATA device - setting the SRST (software reset) bit in the Device Control register. Serial ATA has a more robust mechanism called COMRESET, also referred to as port reset. A port reset is the preferred mechanism for error recovery and should be used in place of software reset. Commit e2a5d9b3d9c3 ("hw/ide/ahci: simplify and document PxCI handling") improved the handling of PxCI, such that PxCI gets cleared after handling a non-NCQ, or NCQ command (instead of incorrectly clearing PxCI after receiving anything - even a FIS that failed to parse, which should NOT clear PxCI, so that you can see which command slot that caused an error). However, simply clearing PxCI after a non-NCQ, or NCQ command, is not enough, we also need to clear PxCI when receiving a SRST in the Device Control register. A legacy software reset is performed by the host sending two H2D FISes, the first H2D FIS asserts SRST, and the second H2D FIS deasserts SRST. The first H2D FIS will not get a D2H reply, and requires the FIS to have the C bit set to one, such that the HBA itself will clear the bit in PxCI. The second H2D FIS will get a D2H reply once the diagnostic is completed. The clearing of the bit in PxCI for this command should ideally be done in ahci_init_d2h() (if it was a legacy software reset that caused the reset (a COMRESET does not use a command slot)). However, since the reset value for PxCI is 0, modify ahci_reset_port() to actually clear PxCI to 0, that way we can avoid complex logic in ahci_init_d2h(). This fixes an issue for FreeBSD where the device would fail to reset. The problem was not noticed in Linux, because Linux uses a COMRESET instead of a legacy software reset by default.

2023-11-21hw/xen: clean up xen_block_find_free_vdev() to avoid Coverity false positiveDavid Woodhouse
Coverity couldn't see that nr_existing was always going to be zero when qemu_xen_xs_directory() returned NULL in the ENOENT case (CID 1523906). Perhaps more to the point, neither could Peter at first glance. Improve the code to hopefully make it clearer to Coverity and human reviewers alike.

2023-11-21ppc/pnv: Fix PNV I2C invalid status after resetGlenn Miles
The PNV I2C Controller was clearing the status register after a reset without repopulating the "upper threshold for I2C ports", "Command Complete" and the SCL/SDA input level fields. Fixed this for resets caused by a system reset as well as from writing to the "Immediate Reset" register.

2023-11-21ppc/pnv: PNV I2C engines assigned incorrect XSCOM addressesGlenn Miles
The PNV I2C engines for power9 and power10 were being assigned a base XSCOM address that was off by one I2C engine's address range such that engine 0 had engine 1's address and so on. The xscom address assignment was being based on the device tree engine numbering, which starts at 1. Rather than changing the device tree numbering to start with 0, the addressing was changed to be based on the existing device tree numbers minus one.

Coverity warns that "i2c_bus_busy(i2c->busses[i]) << i" might overflow because the expression is evaluated using 32-bit arithmetic and then used in a context expecting a uint64_t. While we are at it, introduce a PNV_I2C_MAX_BUSSES constant and check the number of busses at realize time.
