* hw/isa/piix3: Modernize reset handlingBernhard Beschow2022-10-311-5/+3Star
| | | | | | | | | | | | | | Rather than registering the reset handler via a function which appends the handler to a global list, prefer to implement it as a virtual method - PIIX4 does the same already. Note that this means that piix3_reset can now also be called writing to the relevant configuration space register on a PCI bridge.

| * | virtio-net: fix bottom-half packet TX on asynchronous completionLaurent Vivier2022-10-281-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When virtio-net is used with the socket netdev backend, the backend can be busy and not able to collect new packets. In this case, net_socket_receive() returns 0 and registers a poll function to detect when the socket is ready again. In virtio_net_tx_bh(), virtio_net_flush_tx() forwards the 0, the virtio notifications are disabled and the function is not re-scheduled, waiting for the backend to be ready. When the socket netdev backend is again able to send packets, the poll function re-starts to flush remaining packets. This is done by calling virtio_net_tx_complete(). It re-enables notifications and calls again virtio_net_flush_tx(). But it seems if virtio_net_flush_tx() reaches the tx_burst value all the queue is not flushed and no new notification is sent to re-schedule virtio_net_tx_bh(). Nothing re-start to flush the queue and remaining packets are stuck in the queue. To fix that, detect in virtio_net_tx_complete() if virtio_net_flush_tx() has been stopped by tx_burst and if yes re-schedule the bottom half function virtio_net_tx_bh() to flush the remaining packets. This is what is done in virtio_net_tx_bh() when the virtio_net_flush_tx() is synchronous, and completly by-passed when the operation needs to be asynchronous.

There is no equivalent ->ram_block_removed() call when a RAMBlockNotifier is removed. The util/vfio-helpers.c code (the sole user of RAMBlockNotifier) is fine with this asymmetry because it does not rely on RAMBlockNotifier for cleanup. It walks its internal list of DMA mappings and unmaps them by itself. Future users of RAMBlockNotifier may not have an internal data structure that records added RAMBlocks so they will need ->ram_block_removed() callbacks. This patch makes ram_block_notifier_remove() symmetric with respect to callbacks. Now util/vfio-helpers.c needs to unmap remaining DMA mappings after ram_block_notifier_remove() has been called. This is necessary since users like block/nvme.c may create additional DMA mappings that do not originate from the RAMBlockNotifier.

* | | | mips/malta: pass RNG seed via env var and re-randomize on rebootJason A. Donenfeld2022-10-271-0/+27

This mechanism works across all different environment block types, generically, which pass some block via the second firmware argument. On malta, this has been tested to work when passed as an argument from U-Boot's linux_env_set. As is the case on most other architectures (such as boston), when booting with `-kernel`, QEMU, acting as the bootloader, should pass the RNG seed, so that the machine has good entropy for Linux to consume. So this commit implements that quite simply by using the guest random API, which is what is used on nearly all other archs too. It also reinitializes the seed on reboot, so that it is always fresh.
