2021-05-14hw/smbios: support for type 41 (onboard devices extended information)Vincent Bernat3-4/+131
Type 41 defines the attributes of devices that are onboard. The original intent was to imply the BIOS had some level of control over the enablement of the associated devices. If network devices are present in this table, by default, udev will name the corresponding interfaces enoX, X being the instance number. Without such information, udev will fallback to using the PCI ID and this usually gives ens3 or ens4. This can be a bit annoying as the name of the network card may depend on the order of options and may change if a new PCI device is added earlier on the commande line. Being able to provide SMBIOS type 41 entry ensure the name of the interface won't change and helps the user guess the right name without booting a first time. This can be invoked with: $QEMU -netdev user,id=internet -device virtio-net-pci,mac=50:54:00:00:00:42,netdev=internet,id=internet-dev \ -smbios type=41,designation='Onboard LAN',instance=1,kind=ethernet,pcidev=internet-dev The PCI segment is assumed to be 0. This should hold true for most cases. $ dmidecode -t 41 # dmidecode 3.3 Getting SMBIOS data from sysfs. SMBIOS 2.8 present.

2021-05-14virtio-scsi: Configure all host notifiers in a single MR transactionGreg Kurz1-0/+16
This allows the virtio-scsi-pci device to batch the setup of all its host notifiers. This significantly improves boot time of VMs with a high number of vCPUs, e.g. from 6m5.563s down to 1m2.884s for a pseries machine with 384 vCPUs. Note that memory_region_transaction_commit() must be called before virtio_bus_cleanup_host_notifier() because the latter might close ioeventfds that the transaction still assumes to be around when it commits.

2021-05-14virtio-scsi: Set host notifiers and callbacks separatelyGreg Kurz1-18/+22
Host notifiers are guaranteed to be idle until the callbacks are hooked up with virtio_queue_aio_set_host_notifier_handler(). They thus don't need to be set or unset with the AioContext lock held. Do this outside the critical section, like virtio-blk already does : basically downgrading virtio_scsi_vring_init() to only setup the host notifier and set the callback in the caller. This will allow to batch addition/deletion of ioeventds in a single memory transaction, which is expected to greatly improve initialization time.

2021-05-14virtio-blk: Fix rollback path in virtio_blk_data_plane_start()Greg Kurz1-2/+9
When dataplane multiqueue support was added in QEMU 2.7, the path that would rollback guest notifiers assignment in case of error simply got dropped. Later on, when Error was added to blk_set_aio_context() in QEMU 4.1, another error path was introduced, but it ommits to rollback both host and guest notifiers. It seems cleaner to fix the rollback path in one go. The patch is simple enough that it can be adjusted if backported to a pre-4.1 QEMU.

2021-05-13migrate/ram: remove "ram_bulk_stage" and "fpo_enabled"David Hildenbrand2-6/+1
The bulk stage is kind of weird: migration_bitmap_find_dirty() will indicate a dirty page, however, ram_save_host_page() will never save it, as migration_bitmap_clear_dirty() detects that it is not dirty. We already fill the bitmap in ram_list_init_bitmaps() with ones, marking everything dirty - it didn't used to be that way, which is why we needed an explicit first bulk stage. Let's simplify: make the bitmap the single source of thuth. Explicitly handle the "xbzrle_enabled after first round" case. Regarding XBZRLE (implicitly handled via "ram_bulk_stage = false" right now), there is now a slight change in behavior: - Colo: When starting, it will be disabled (was implicitly enabled) until the first round actually finishes. - Free page hinting: When starting, XBZRLE will be disabled (was implicitly enabled) until the first round actually finished. - Snapshots: When starting, XBZRLE will be disabled. We essentially only do a single run, so I guess it will never actually get disabled. Postcopy seems to indirectly disable it in ram_save_page(), so there shouldn't be really any change.

2021-05-13hw/avr/atmega.c: use the avr51 cpu for atmega1280Frederic Konrad1-1/+1
According to the as documentation: (https://sourceware.org/binutils/docs-2.36/as/AVR-Options.html) "Instruction set avr51 is for the enhanced AVR core with exactly 128K program memory space (MCU types: atmega128, atmega128a, atmega1280, atmega1281, atmega1284, atmega1284p, atmega128rfa1, atmega128rfr2, atmega1284rfr2, at90can128, at90usb1286, at90usb1287, m3000)." But when compiling a program for atmega1280 or avr51 and trying to execute it: $ cat > test.S << EOF > loop: > rjmp loop > EOF $ avr-gcc -nostdlib -nostartfiles -mmcu=atmega1280 test.S -o test.elf $ qemu-system-avr -serial mon:stdio -nographic -no-reboot -M mega \ -bios test.elf qemu-system-avr: Current machine: Arduino Mega (ATmega1280) with 'avr6' CPU qemu-system-avr: ELF image 'test.elf' is for 'avr51' CPU So this fixes the atmega1280 class to use an avr51 CPU.

TYPE_MC146818_RTC is an ISA device, so its DeviceClass::reset() handler is called automatically when its qbus parent is reset (we don't need to register it manually). We have 2 reset() methods: a generic one and the qdev one. Merge them into a reset_enter handler (keeping the IRQ lowering to a reset_hold one), and remove the qemu_register_reset() call.
