* hw/net/e1000: Remove unused E1000_FLAG_MAC flagPhilippe Mathieu-Daudé2025-05-301-54/+41
| | | | | | | | | | | | | | | E1000_FLAG_MAC was only used by the hw_compat_2_4[] array, via the 'extra_mac_registers=off' property. We removed all machines using that array, lets remove all the code around E1000_FLAG_MAC, including the MAC_ACCESS_FLAG_NEEDED enum, similarly to commit fa4ec9ffda7 ("e1000: remove old compatibility code").

* hw, target: Add ResetType argument to hold and exit phase methodsPeter Maydell2024-04-251-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | We pass a ResetType argument to the Resettable class enter phase method, but we don't pass it to hold and exit, even though the callsites have it readily available. This means that if a device cared about the ResetType it would need to record it in the enter phase method to use later on. Pass the type to all three of the phase methods to avoid having to do that.

| | | | | | | | | | | | | | | | | | Before this change, e1000 and the common code updated BPRC and MPRC depending on the matched filter, but e1000e and igb decided to update those counters by deriving the packet type independently. This inconsistency caused a multicast packet to be counted twice. Updating BPRC and MPRC depending on are fundamentally flawed anyway as a filter can be used for different types of packets. For example, it is possible to filter broadcast packets with MTA. Always determine what counters to update by inspecting the packets.

* e1000: set RX descriptor status in a separate operationDing Hui2022-07-061-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The code of setting RX descriptor status field maybe work fine in previously, however with the update of glibc version, it shows two issues when guest using dpdk receive packets: 1. The dpdk has a certain probability getting wrong buffer_addr this impact may be not obvious, such as lost a packet once in a while 2. The dpdk may consume a packet twice when scan the RX desc queue over again this impact will lead a infinite wait in Qemu, since the RDT (tail pointer) be inscreased to equal to RDH by unexpected, which regard as the RX desc queue is full Write a whole of RX desc with DD flag on is not quite correct, because when the underlying implementation of memcpy using XMM registers to copy e1000_rx_desc (when AVX or something else CPU feature is usable), the bytes order of desc writing to memory is indeterminacy We can use full-scale test case to reproduce the issue-2 by https://github.com/BASM/qemu_dpdk_e1000_test (thanks to Leonid Myravjev) I also write a POC test case at https://github.com/cdkey/e1000_poc which can reproduce both of them, and easy to verify the patch effect. The hw watchpoint also shows that, when Qemu using XMM related instructions writing 16 bytes e1000_rx_desc, concurrent with DPDK using movb writing 1 byte status, the final result of writing to memory will be one of them, if it made by Qemu which DD flag is on, DPDK will consume it again. Setting DD status in a separate operation, can prevent the impact of disorder memory writing by memcpy, also avoid unexpected data when concurrent writing status by qemu and guest dpdk.

| | | | | | | | | | | | | | | | | The fact that the MMIO handler is not re-entrant causes an infinite loop under certain conditions: Guest write to TDT -> Loopback -> RX (DMA to TDT) -> TX We now eliminate the effect of this problem locally in e1000, by adding a boolean in struct E1000State indicating when the TX side is busy.

| | | | | | | | | | | | | | | | | | QOM object initialization runs .instance_init() for the type and all its supertypes; see object_init_with_type(). Both TYPE_E1000_BASE and its concrete subtypes set .instance_init() to e1000_instance_init(). For the concrete subtypes, it duly gets run twice. The second run fails, but the error gets ignored (a later commit will change that). Remove it from the subtypes.

Many places including hw/qdev-properties.h (directly or via hw/qdev.h) actually need only hw/qdev-core.h. Include hw/qdev-core.h there instead. hw/qdev.h is actually pointless: all it does is include hw/qdev-core.h and hw/qdev-properties.h, which in turn includes hw/qdev-core.h. Replace the remaining uses of hw/qdev.h by hw/qdev-properties.h. While there, delete a few superfluous inclusions of hw/qdev-core.h. Touching hw/qdev-properties.h now recompiles some 1200 objects.
