2020-07-24hw: Only compile the usb-dwc2 controller if it is really neededThomas Huth
The USB_DWC2 switch is currently "default y", so it is included in all qemu-system-* builds, even if it is not needed. Even worse, it does a "select USB", so USB devices are now showing up as available on targets that do not support USB at all. This sysbus device should only be included by the boards that need it, i.e. by the Raspi machines.

2020-07-21qom: Change object_get_canonical_path_component() not to mallocMarkus Armbruster
object_get_canonical_path_component() returns a malloced copy of a property name on success, null on failure. 19 of its 25 callers immediately free the returned copy. Change object_get_canonical_path_component() to return the property name directly. Since modifying the name would be wrong, adjust the return type to const char *. Drop the free from the 19 callers become simpler, add the g_strdup() to the other six.

Root cause is m2sxxx_soc_initfn()'s messing with nd_table[] via qemu_check_nic_model(). That's wrong. We fixed the exact same bug for device "allwinner-a10" in commit 8aabc5437b "hw/arm/allwinner-a10: Do not use nd_table in instance_init function". Fix this instance the same way: move the offending code to m2sxxx_soc_realize(), where it's less wrong, and add a FIXME comment.

2020-07-20hw/arm/armsse: Assert info->num_cpus is in-bounds in armsse_realize()Peter Maydell
In armsse_realize() we have a loop over [0, info->num_cpus), which indexes into various fixed-size arrays in the ARMSSE struct. This confuses Coverity, which warns that we might overrun those arrays (CID 1430326, 1430337, 1430371, 1430414, 1430430). This can't actually happen, because the info struct is always one of the entries in the armsse_variants[] array and num_cpus is either 1 or 2; we also already assert in armsse_init() that num_cpus is not too large. However, adding an assert to armsse_realize() like the one in armsse_init() should help Coverity figure out that these code paths aren't possible.

The "when != lbl:" is necessary to avoid transforming if (fun(args, &err)) { goto out } ... out: error_propagate(errp, err); even though other paths to label out still need the error_propagate(). For an actual example, see sclp_realize(). Without the "when strict", Coccinelle transforms vfio_msix_setup(), incorrectly. I don't know what exactly "when strict" does, only that it helps here. The match of return is narrower than what I want, but I can't figure out how to express "return where the operand doesn't use @err". For an example where it's too narrow, see vfio_intx_enable().

2020-07-03Replace uses of FROM_SSI_SLAVE() macro with QOM castsPeter Maydell
The FROM_SSI_SLAVE() macro predates QOM and is used as a typesafe way to cast from an SSISlave* to the instance struct of a subtype of TYPE_SSI_SLAVE. Switch to using the QOM cast macros instead, which have the same effect (by writing the QOM macros if the types were previously missing them.) (The FROM_SSI_SLAVE() macro allows the SSISlave member of the subtype's struct to be anywhere as long as it is named "ssidev", whereas a QOM cast macro insists that it is the first thing in the subtype's struct. This is true for all the types we convert here.) This removes all the uses of FROM_SSI_SLAVE() so we can delete the definition.

2020-07-03hw/arm/spitz: Encapsulate misc GPIO handling in a devicePeter Maydell
Currently we have a free-floating set of IRQs and a function spitz_out_switch() which handle some miscellaneous GPIO lines for the spitz board. Encapsulate this behaviour in a simple QOM device. At this point we can finally remove the 'max1111' global, because the ADC battery-temperature value is now handled by the misc-gpio device writing the value to its outbound "adc-temp" GPIO, which the board code wires up to the appropriate inbound GPIO line on the max1111. This commit also fixes Coverity issue CID 1421913 (which pointed out that the 'outsignals' in spitz_scoop_gpio_setup() were leaked), because it removes the use of the qemu_allocate_irqs() API from this code entirely.

2020-07-03hw/misc/max111x: Use GPIO lines rather than max111x_set_input()Peter Maydell
The max111x ADC device model allows other code to set the level on the 8 ADC inputs using the max111x_set_input() function. Replace this with generic qdev GPIO inputs, which also allow inputs to be set to arbitrary values. Using GPIO lines will make it easier for board code to wire things up, so that if device A wants to set the ADC input it doesn't need to have a direct pointer to the max111x but can just set that value on its output GPIO, which is then wired up by the board to the appropriate max111x input.

2020-07-03hw/arm/virt-acpi-build: Only expose flash on older machine typesAndrew Jones
The flash device is exclusively for the host-controlled firmware, so we should not expose it to the OS. Exposing it risks the OS messing with it, which could break firmware runtime services and surprise the OS when all its changes disappear after reboot. As firmware needs the device and uses DT, we leave the device exposed there. It's up to firmware to remove the nodes from DT before sending it on to the OS. However, there's no need to force firmware to remove tables from ACPI (which it doesn't know how to do anyway), so we simply don't add the tables in the first place. But, as we've been adding the tables for quite some time and don't want to change the default hardware exposed to versioned machines, then we only stop exposing the flash device tables for 5.1 and later machine types.

2020-07-03hw/arm/virt: Let the virtio-iommu bypass MSIsEric Auger
At the moment the virtio-iommu translates MSI transactions. This behavior is inherited from ARM SMMU. The virt machine code knows where the guest MSI doorbells are so we can easily declare those regions as VIRTIO_IOMMU_RESV_MEM_T_MSI. With that setting the guest will not map MSIs through the IOMMU and those transactions will be simply bypassed. Depending on which MSI controller is in use (ITS or GICV2M), we declare either: - the ITS interrupt translation space (ITS_base + 0x10000), containing the GITS_TRANSLATOR or - The GICV2M single frame, containing the MSI_SETSP_NS register.

2020-07-03numa: Auto-enable NUMA when any memory devices are possibleDavid Hildenbrand
Let's auto-enable it also when maxmem is specified but no slots are defined. This will result in us properly creating ACPI srat tables, indicating the maximum possible PFN to the guest OS. Based on this, e.g., Linux will enable the swiotlb properly. This avoids having to manually force the switolb on (swiotlb=force) in Linux in case we're booting only using DMA memory (e.g., 2GB on x86-64), and virtio-mem adds memory later on that really needs the swiotlb to be used for DMA. Let's take care of backwards compatibility if somebody has a setup that specifies "maxram" without "slots".
