2023-04-20hw/net/imx_fec: Support two Ethernet interfaces connected to single MDIO busGuenter Roeck
The SOC on i.MX6UL and i.MX7 has 2 Ethernet interfaces. The PHY on each may be connected to separate MDIO busses, or both may be connected on the same MDIO bus using different PHY addresses. Commit 461c51ad4275 ("Add a phy-num property to the i.MX FEC emulator") added support for specifying PHY addresses, but it did not provide support for linking the second PHY on a given MDIO bus to the other Ethernet interface. To be able to support two PHY instances on a single MDIO bus, two properties are needed: First, there needs to be a flag indicating if the MDIO bus on a given Ethernet interface is connected. If not, attempts to read from this bus must always return 0xffff. Implement this property as phy-connected. Second, if the MDIO bus on an interface is active, it needs a link to the consumer interface to be able to provide PHY access for it. Implement this property as phy-consumer.

2023-04-12migration: Fix potential race on postcopy_qemufile_srcPeter Xu
postcopy_qemufile_src object should be owned by one thread, either the main thread (e.g. when at the beginning, or at the end of migration), or by the return path thread (when during a preempt enabled postcopy migration). If that's not the case the access to the object might be racy. postcopy_preempt_shutdown_file() can be potentially racy, because it's called at the end phase of migration on the main thread, however during which the return path thread hasn't yet been recycled; the recycle happens in await_return_path_close_on_source() which is after this point. It means, logically it's posslbe the main thread and the return path thread are both operating on the same qemufile. While I don't think qemufile is thread safe at all. postcopy_preempt_shutdown_file() used to be needed because that's where we send EOS to dest so that dest can safely shutdown the preempt thread. To avoid the possible race, remove this only place that a race can happen. Instead we figure out another way to safely close the preempt thread on dest. The core idea during postcopy on deciding "when to stop" is that dest will send a postcopy SHUT message to src, telling src that all data is there. Hence to shut the dest preempt thread maybe better to do it directly on dest node. This patch proposed such a way that we change postcopy_prio_thread_created into PreemptThreadStatus, so that we kick the preempt thread on dest qemu by a sequence of: mis->preempt_thread_status = PREEMPT_THREAD_QUIT; qemu_file_shutdown(mis->postcopy_qemufile_dst); While here shutdown() is probably so far the easiest way to kick preempt thread from a blocked qemu_get_be64(). Then it reads preempt_thread_status to make sure it's not a network failure but a willingness to quit the thread. We could have avoided that extra status but just rely on migration status. The problem is postcopy_ram_incoming_cleanup() is just called early enough so we're still during POSTCOPY_ACTIVE no matter what.. So just make it simple to have the status introduced. One flag x-preempt-pre-7-2 is added to keep old pre-7.2 behaviors of postcopy preempt.

2023-04-11hw/i2c/allwinner-i2c: Fix subclassing of TYPE_AW_I2C_SUN6IPeter Maydell
In commit 8461bfdca9c we added the TYPE_AW_I2C_SUN6I, which is a minor variant of the TYPE_AW_I2C device. However, we didn't quite get the class hierarchy right. We made the new TYPE_AW_I2C_SUN6I a subclass of TYPE_SYS_BUS_DEVICE, which means that you can't validly use a pointer to this object via the AW_I2C() cast macro, which insists on having something that is an instance of TYPE_AW_I2C or some subclass of that type. This only causes a problem if QOM cast macro debugging is enabled; that is supposed to be on by default, but a mistake in the meson conversion in commit c55cf6ab03f4c meant that it ended up disabled by default, and we didn't catch this bug. Fix the problem by arranging the classes in the same way we do for TYPE_PL011 and TYPE_PL011_LUMINARY in hw/char/pl011.c -- make the variant class be a subclass of the "normal" version of the device. This was reported in https://gitlab.com/qemu-project/qemu/-/issues/1586 but this fix alone isn't sufficient, as there is a separate cast-related issue in the CXL code in pci_expander_bridge.c.

2023-04-03hw/arm: do not free machine->fdt in arm_load_dtb()Markus Armbruster
At this moment, arm_load_dtb() can free machine->fdt when binfo->dtb_filename is NULL. If there's no 'dtb_filename', 'fdt' will be retrieved by binfo->get_dtb(). If get_dtb() returns machine->fdt, as is the case of machvirt_dtb() from hw/arm/virt.c, fdt now has a pointer to machine->fdt. And, in that case, the existing g_free(fdt) at the end of arm_load_dtb() will make machine->fdt point to an invalid memory region. Since monitor command 'dumpdtb' was introduced a couple of releases ago, running it with any ARM machine that uses arm_load_dtb() will crash QEMU. Let's enable all arm_load_dtb() callers to use dumpdtb properly. Instead of freeing 'fdt', assign it back to ms->fdt.

2023-03-30hw/mips/gt64xxx_pci: Don't endian-swap GT_PCI0_CFGADDRJiaxun Yang
145e2198d749 ("hw/mips/gt64xxx_pci: Endian-swap using PCI_HOST_BRIDGE MemoryRegionOps") converted CFGADDR/CFGDATA registers to use PCI_HOST_BRIDGE's accessor facility and enabled byte swap for both CFGADDR/CFGDATA register. However CFGADDR as a ISD internal register is not controlled by MByteSwap bit, it follows endian of all other ISD register, which means it ties to little endian. Move mapping of CFGADDR out of gt64120_update_pci_cfgdata_mapping to disable endian-swapping.

2023-03-28igb: respect VMVIR and VMOLR for VLANSriram Yagnaraman
Add support for stripping/inserting VLAN for VFs. Had to move CSUM calculation back into the for loop, since packet data is pulled inside the loop based on strip VLAN decision for every VF. net_rx_pkt_fix_l4_csum should be extended to accept a buffer instead for igb.

2023-03-28igb: Fix DMA requester specification for Tx packetAkihiko Odaki
igb used to specify the PF as DMA requester when reading Tx packets. This made Tx requests from VFs to be performed on the address space of the PF, defeating the purpose of SR-IOV. Add some logic to change the requester depending on the queue, which can be assigned to a VF.

2023-03-28igb: Save more Tx statesAkihiko Odaki
The current implementation of igb uses only part of a advanced Tx context descriptor and first data descriptor because it misses some features and sniffs the trait of the packet instead of respecting the packet type specified in the descriptor. However, we will certainly need the entire Tx context descriptor when we update igb to respect these ignored fields. Save the entire context descriptor and first data descriptor except the buffer address to prepare for such a change. This also introduces the distinction of contexts with different indexes, which was not present in e1000e but in igb.

Since the nvme_blk_read/write are used by both the data and metadata portions of the IO, it can't have the 512B alignment requirement. Without this change any metadata transfer, which length isn't a multiple of 512B and which is bigger than 512B, will result in only a partial transfer.
