2024-12-31hw/i386: Mark devices as little-endianPhilippe Mathieu-Daudé5-6/+6
These devices are only used by the X86 targets, which are only built as little-endian. Therefore the DEVICE_NATIVE_ENDIAN definition expand to DEVICE_LITTLE_ENDIAN (besides, the DEVICE_BIG_ENDIAN case isn't tested). Simplify directly using DEVICE_LITTLE_ENDIAN.

2024-12-31hw/misc/ivshmem-flat: Add ivshmem-flat deviceGustavo Romero4-0/+482
Add a new device, ivshmem-flat, which is similar to the ivshmem PCI but does not require a PCI bus. It's meant to be used on machines like those with Cortex-M MCUs, which usually lack a PCI/PCIe bus, e.g. lm3s6965evb and mps2-an385. The device currently only supports the sysbus bus. The new device, just like the ivshmem PCI device, supports both peer notification via hardware interrupts and shared memory. The device shared memory size can be set using the 'shmem-size' option and it defaults to 4 MiB, which is the default size of shmem allocated by the ivshmem server.

2024-12-30hw/pci-host/gpex: Allow more than 4 legacy IRQsAlexander Graf10-33/+58
Some boards such as vmapple don't do real legacy PCI IRQ swizzling. Instead, they just keep allocating more board IRQ lines for each new legacy IRQ. Let's support that mode by giving instantiators a new "nr_irqs" property they can use to support more than 4 legacy IRQ lines. In this mode, GPEX will export more IRQ lines, one for each device.

These devices are only used by the M68K target, which is only built as big-endian. Therefore the DEVICE_NATIVE_ENDIAN definition expand to DEVICE_BIG_ENDIAN (besides, the DEVICE_LITTLE_ENDIAN case isn't tested). Simplify directly using DEVICE_BIG_ENDIAN.

For CPU object, possible_cpu_arch_ids() function is used rather than smp.cpus.

2024-12-26vfio/migration: Rename vfio_devices_all_dirty_tracking()Avihai Horon1-2/+2
vfio_devices_all_dirty_tracking() is used to check if dirty page log sync is needed. However, besides checking the dirty page tracking status, it also checks the pre_copy_dirty_page_tracking flag. Rename it to vfio_devices_log_sync_needed() which reflects its purpose more accurately and makes the code clearer as there are already several helpers with similar names.

2024-12-26vfio/migration: Refactor vfio_devices_all_running_and_mig_active() logicAvihai Horon2-33/+9
During DMA unmap with vIOMMU, vfio_devices_all_running_and_mig_active() is used to check whether a dirty page log sync of the unmapped pages is required. Such log sync is needed during migration pre-copy phase, and the current logic detects it by checking if migration is active and if the VFIO devices are running. However, recently there has been an effort to simplify the migration status API and reduce it to a single migration_is_running() function. To accommodate this, refactor vfio_devices_all_running_and_mig_active() logic so it won't use migration_is_active(). Do it by simply checking if dirty tracking has been started using internal VFIO flags. This should be equivalent to the previous logic as during migration dirty tracking is active and when the guest is stopped there shouldn't be DMA unmaps coming from it. As a side effect, now that migration status is no longer used, DMA unmap log syncs are untied from migration. This will make calc-dirty-rate more accurate as now it will also include VFIO dirty pages that were DMA unmapped. Also rename the function to properly reflect its new logic and extract common code from vfio_devices_all_dirty_tracking().
