2021-09-20hw/arm/aspeed: Allow machine to set UART defaultPeter Delevoryas
When you run QEMU with an Aspeed machine and a single serial device using stdio like this: qemu -machine ast2600-evb -drive ... -serial stdio The guest OS can read and write to the UART5 registers at 0x1E784000 and it will receive from stdin and write to stdout. The Aspeed SoC's have a lot more UART's though (AST2500 has 5, AST2600 has 13) and depending on the board design, may be using any of them as the serial console. (See "stdout-path" in a DTS to check which one is chosen). Most boards, including all of those currently defined in hw/arm/aspeed.c, just use UART5, but some use UART1. This change adds some flexibility for different boards without requiring users to change their command-line invocation of QEMU. I tested this doesn't break existing code by booting an AST2500 OpenBMC image and an AST2600 OpenBMC image, each using UART5 as the console. Then I tested switching the default to UART1 and booting an AST2600 OpenBMC image that uses UART1, and that worked too.

2021-09-13qdev: Support marking individual buses as 'full'Peter Maydell
By default, QEMU will allow devices to be plugged into a bus up to the bus class's device count limit. If the user creates a device on the command line or via the monitor and doesn't explicitly specify the bus to plug it in, QEMU will plug it into the first non-full bus that it finds. This is fine in most cases, but some machines have multiple buses of a given type, some of which are dedicated to on-board devices and some of which have an externally exposed connector for user-pluggable devices. One example is I2C buses. Provide a new function qbus_mark_full() so that a machine model can mark this kind of "internal only" bus as 'full' after it has created all the devices that should be plugged into that bus. The "find a non-full bus" algorithm will then skip the internal-only bus when looking for a place to plug in user-created devices.

Device active and subchannel active, however, are (due to the subchannel becoming status pending with primary respectively secondary status). The other conditions in the actl are only cleared when the guest executes tsch on the subchannel.

2021-09-04hw/pci: remove all references to find_i440fx functionAni Sinha
commit c0e427d6eb5fefc538 ("hw/acpi/ich9: Enable ACPI PCI hot-plug") removed all uses of find_i440fx() function. This has been replaced by the more generic call acpi_get_i386_pci_host() which maybe able to find the root bus both for i440fx machine type as well as for the q35 machine type. There seems to be no more any need to maintain a i440fx specific version of the api call. Remove it. Tested by building from a clean tree successfully.

2021-09-04hw/acpi: define PIIX4 acpi pci hotplug property strings at a single placeAni Sinha
Now that we have "acpi-pci-hotplug-with-bridge-support" PIIX4 PM property being used for both q35 and i440fx machine types, it is better that we defined this property string at a single place within a header file like other PIIX4 properties. We can then use this single definition at all the places that needs it instead of duplicating the string everywhere. While at it, this change also adds a definition for "acpi-root-pci-hotplug" PIIX4 PM property and uses this definition at all places that were formally using the string value.

2021-09-04vhost-vdpa: Do not send empty IOTLB update batchesEugenio Pérez
With the introduction of the batch hinting, meaningless batches can be created with no IOTLB updates if the memory region was skipped by vhost_vdpa_listener_skipped_section. This is the case of host notifiers memory regions, device un/realize, and others. This causes the vdpa device to receive dma mapping settings with no changes, a possibly expensive operation for nothing. To avoid that, VHOST_IOTLB_BATCH_BEGIN hint is delayed until we have a meaningful (not skipped section) mapping or unmapping operation, and VHOST_IOTLB_BATCH_END is not written unless at least one of _UPDATE / _INVALIDATE has been issued. v3: * Use a bool instead of a counter avoiding potential number wrapping * Fix bad check on _commit * Move VHOST_BACKEND_F_IOTLB_BATCH check to vhost_vdpa_iotlb_batch_begin_once v2 (from RFC): * Rename misleading name * Abstract start batching function for listener_add/del Signed-off-by: Eugenio Pérez <eperezma@redhat.com> Message-Id: <20210812140933.226288-1-eperezma@redhat.com> Acked-by: Jason Wang <jasowang@redhat.com> Reviewed-by: Michael S.

2021-09-01hw/timer/stellaris-gptm: Use Clock input instead of system_clock_scalePeter Maydell
The stellaris-gptm timer currently uses system_clock_scale for one of its timer modes where the timer runs at the CPU clock rate. Make it use a Clock input instead. We don't try to make the timer handle changes in the clock frequency while the downcounter is running. This is not a change in behaviour from the previous system_clock_scale implementation -- we will pick up the new frequency only when the downcounter hits zero. Handling dynamic clock changes when the counter is running would require state that the current gptm implementation doesn't have.
