2018-09-25hw/net/pcnet-pci: Unify pcnet_ioport_read/write and pcnet_mmio_read/writePeter Maydell
The only difference between our implementation of the pcnet ioport accessors and the mmio accessors is that the former check BCR_DWIO to see what access widths are permitted for addresses in the aprom range (0x0..0xf). In fact our failure to do this in the mmio accessors is a bug (one which was fixed for the ioport accessors in commit 7ba79741970 in 2011). The data sheet for the Am79C970A does not describe the DWIO bit as only applying for I/O space mapped I/O resources and not memory mapped I/O resources, and our MMIO accessors already honour DWIO for accesses in the 0x10..0x1f range (since the pcnet_ioport_{read,write}{w,l} functions check it). The data sheet for the later but compatible Am79C976 is clearer: it states specifically "DWIO mode applies to both I/O- and memory-mapped acceses." This seems to be reasonable evidence in favour of interpretating the Am79C970A spec as being the same. (NB: Linux's pcnet driver only supports I/O accesses, so the MMIO access part of this device is probably untested anyway.)

2018-09-25hw/net/pcnet-pci: Convert away from old_mmio accessorsPeter Maydell
Convert the pcnet-pci device away from using the old_mmio MemoryRegionOps accessor functions. This commit is a no-behaviour-change API conversion. (Since PCNET_PNPMMIO_SIZE is 0x20, the old "addr & 0x10" check and the new "addr < 0x10" check are exact opposites; the new code is phrased to be parallel with the pcnet_io_read/write functions.) I have left a TODO comment marker because the similarity between the MMIO and IO accessor behaviour is suspicious and they could be combined, but this will be left to a different patch.

2018-08-28qapi: Drop qapi_event_send_FOO()'s Error ** argumentPeter Xu
The generated qapi_event_send_FOO() take an Error ** argument. They can't actually fail, because all they do with the argument is passing it to functions that can't fail: the QObject output visitor, and the @qmp_emit callback, which is either monitor_qapi_event_queue() or event_test_emit(). Drop the argument, and pass &error_abort to the QObject output visitor and @qmp_emit instead.

2018-07-16etsec: fix IRQ (un)maskingMichael Davidsaver
Interrupt conditions occurring while masked are not being signaled when later unmasked. The fix is to raise/lower IRQs when IMASK is changed. To avoid problems like this in future, consolidate IRQ pin update logic in one function. Also fix probable typo "IEVENT_TXF | IEVENT_TXF", and update IRQ pins on reset.

2018-07-09hw/net/dp8393x: don't make prom region 'nomigrate'Peter Maydell
Currently we use memory_region_init_rom_nomigrate() to create the "dp3893x-prom" memory region, and we don't manually register it with vmstate_register_ram(). This currently means that its contents are migrated but as a ram block whose name is the empty string; in future it may mean they are not migrated at all. Use memory_region_init_ram() instead. Note that this is a a cross-version migration compatibility break for the MIPS "magnum" and "pica61" machines.

2018-06-12object: fix OBJ_PROP_LINK_UNREF_ON_RELEASE ambivalenceMarc-André Lureau
A link property can be set during creation, with object_property_add_link() and later with object_property_set_link(). add_link() doesn't add a reference to the target object, while set_link() does. Furthemore, OBJ_PROP_LINK_UNREF_ON_RELEASE flags, set during add_link, says whether a reference must be released when the property is destroyed. This can lead to leaks if the property was later set_link(), as the added reference is never released. Instead, rename OBJ_PROP_LINK_UNREF_ON_RELEASE to OBJ_PROP_LINK_STRONG and use that has an indication on how the link handle reference management in set_link().

2018-03-26virtio_net: flush uncompleted TX on resetGreg Kurz
If the backend could not transmit a packet right away for some reason, the packet is queued for asynchronous sending. The corresponding vq element is tracked in the async_tx.elem field of the VirtIONetQueue, for later freeing when the transmission is complete. If a reset happens before completion, virtio_net_tx_complete() will push async_tx.elem back to the guest anyway, and we end up with the inuse flag of the vq being equal to -1. The next call to virtqueue_pop() is then likely to fail with "Virtqueue size exceeded". This can be reproduced easily by starting a guest with an hubport backend that is not connected to a functional network, eg, -device virtio-net-pci,netdev=hub0 -netdev hubport,id=hub0,hubid=0 and no other -netdev hubport,hubid=0 on the command line. The appropriate fix is to ensure that such an asynchronous transmission cannot survive a device reset. So for all queues, we first try to send the packet again, and eventually we purge it if the backend still could not deliver it. CC: qemu-stable@nongnu.org Reported-by: R.

2018-03-19fsl-imx6: Swap Ethernet interrupt definesGuenter Roeck
The sabrelite machine model used by qemu-system-arm is based on the Freescale/NXP i.MX6Q processor. This SoC has an on-board ethernet controller which is supported in QEMU using the imx_fec.c module (actually called imx.enet for this model.) The include/hw/arm/fsm-imx6.h file defines the interrupt vectors for the imx.enet device like this: #define FSL_IMX6_ENET_MAC_1588_IRQ 118 #define FSL_IMX6_ENET_MAC_IRQ 119 According to https://www.nxp.com/docs/en/reference-manual/IMX6DQRM.pdf, page 225, in Table 3-1. ARM Cortex A9 domain interrupt summary, interrupts are as follows. 150 ENET MAC 0 IRQ 151 ENET MAC 0 1588 Timer interrupt where 150 - 32 == 118 151 - 32 == 119 In other words, the vector definitions in the fsl-imx6.h file are reversed. Fixing the interrupts alone causes problems with older Linux kernels: The Ethernet interface will fail to probe with Linux v4.9 and earlier. Linux v4.1 and earlier will crash due to a bug in Ethernet driver probe error handling. This is a Linux kernel problem, not a qemu problem: the Linux kernel only worked by accident since it requested both interrupts. For backward compatibility, generate the Ethernet interrupt on both interrupt lines. This was shown to work from all Linux kernel releases starting with v3.16.

2018-03-13virtio-net: add linkspeed and duplex settings to virtio-netJason Baron
Although linkspeed and duplex can be set in a linux guest via 'ethtool -s', this requires custom ethtool commands for virtio-net by default. Introduce a new feature flag, VIRTIO_NET_F_SPEED_DUPLEX, which allows the hypervisor to export a linkspeed and duplex setting. The user can subsequently overwrite it later if desired via: 'ethtool -s'. Linkspeed and duplex settings can be set as: '-device virtio-net,speed=10000,duplex=full' where speed is [0...INT_MAX], and duplex is ["half"|"full"].

2018-03-05hw/net: Remove unnecessary header includesThomas Huth
Headers like "hw/loader.h" and "qemu/sockets.h" are not needed in the hw/net/*.c files. And Some other headers are included via other headers already, so we can drop them, too. Signed-off-by: Thomas Huth <thuth@redhat.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
2018-03-02Include less of the generated modular QAPI headersMarkus Armbruster
In my "build everything" tree, a change to the types in qapi-schema.json triggers a recompile of about 4800 out of 5100 objects. The previous commit split up qmp-commands.h, qmp-event.h, qmp-visit.h, qapi-types.h. Each of these headers still includes all its shards. Reduce compile time by including just the shards we actually need. To illustrate the benefits: adding a type to qapi/migration.json now recompiles some 2300 instead of 4800 objects. The next commit will improve it further.
