2015-07-27usbnet: Drop usbnet_can_receiveFam Zheng
usbnet_receive already drops packet if rndis_state is not RNDIS_DATA_INITIALIZED, and queues packet if in buffer is not available. The only difference is s->dev.config but that is similar to rndis_state. Drop usbnet_can_receive and move these checks to usbnet_receive, so that we don't need to explicitly flush the queue when s->dev.config changes value.

The network mcf_fec driver emulated receive side method is returning a result of 0 causing the network layer to disable receive for this emulated device. This results in the guest only ever receiving one packet. Fix the recieve side processing to return the number of bytes that we passed back through to the guest.

2015-07-27hw/net: add simple phy support to mcf_fec driverGreg Ungerer
The Linux fec driver needs at least basic phy support to probe and work. The current qemu mcf_fec emulation has no support for the reading or writing of the MDIO lines to access an attached phy. This code adds a very simple set of register results for a fixed phy setup - very similar to that used on an m5208evb board. This is enough to probe and identify an emulated attached phy.

2015-07-24framebuffer: set DIRTY_MEMORY_VGA on RAM that is used for the framebufferPaolo Bonzini
The MemoryRegionSection contains enough information to access the RAM region underlying the framebuffer, and can be cached inside the display device. By doing this, the new framebuffer_update_memory_section function can enable dirty memory logging on the relevant RAM region. The function must be called whenever the stride or base of the framebuffer changes; a simple way to cover these cases is to call it on every full frame invalidation, which is a rare case. framebuffer_update_display now works entirely on a MemoryRegionSection, without going through cpu_physical_memory_map/unmap.

2015-07-24scsi: Handle no media case for scsi_get_configurationMatthew Rosato
Currently, scsi_get_configuration always returns a current profile (DVD or CD), even when there is actually no media present. By comparison, ide/atapi uses a default profile of 0 (MMC_PROFILE_NONE) for this case and checks for tray_open, so let's do the same for scsi. This fixes a problem I'm seeing with Fedora 22 guests where systemd cdrom_id fails to unmount after a QEMU-initiated eject against a scsi cdrom device because it believes the media is still present (but unreadable).

2015-07-22vfio/pci: Fix RTL8168 NIC quirksAlex Williamson
The RTL8168 quirk correctly describes using bit 31 as a signal to mark a latch/completion, but the code mistakenly uses bit 28. This causes the Realtek driver to spin on this register for quite a while, 20k cycles on Windows 7 v7.092 driver. Then it gets frustrated and tries to set the bit itself and spins for another 20k cycles. For some this still results in a working driver, for others not. About the only thing the code really does in its current form is protect the guest from sneaking in writes to the real hardware MSI-X table. The fix is obviously to use bit 31 as we document that we should. The other problem doesn't seem to affect current drivers as nobody seems to use these window registers for writes to the MSI-X table, but we need to use the stored data when a write is triggered, not the value of the current write, which only provides the offset. Note that only the Windows drivers from Realtek seem to use these registers, the Microsoft drivers provided with Windows 8.1 do not access them, nor do Linux in-kernel drivers.

2015-07-20net/vmxnet3: Fix RX TCP/UDP checksum on partially summed packetsDana Rubin
Convert partially summed packets to be fully checksummed. In case csum offloaded packet, vmxnet3 implementation always passes an RxCompDesc with the "Checksum calculated and found correct" notification to the OS. This emulates the observed ESXi behavior. Therefore, if packet has the NEEDS_CSUM bit set, we must calculate and place a fully computed checksum into the tcp/udp header. Otherwise, the OS driver will receive a checksum-correct indication but with the actual tcp/udp checksum field having just the pseudo header csum value. If host OS performs forwarding, it will forward an incorrectly checksummed packet.

2015-07-20virtio-net: Flush incoming queues when DRIVER_OK is being setFam Zheng
This patch fixes network hang after "stop" then "cont", while network packets keep arriving. Tested both manually (tap, host pinging guest) and with Jason's qtest series (plus his "[PATCH 2.4] socket: pass correct size in net_socket_send()" fix). As virtio_net_set_status is called when guest driver is setting status byte and when vm state is changing, it is a good opportunity to flush queued packets. This is necessary because during vm stop the backend (e.g. tap) would stop rx processing after .can_receive returns false, until the queue is explicitly flushed or purged. The other interesting condition in .can_receive, virtio_queue_ready(), is handled by virtio_net_handle_rx() when guest kicks; the 3rd condition is invalid queue index which doesn't need flushing.

2015-07-16qxl: allow to specify head limit to qxl driverFrediano Ziglio
This patch allow to limit number of heads using qxl driver. By default qxl driver is not limited on any kind on head use so can decide to use as much heads. libvirt has this as a video card parameter (actually set to 1 but not used). This parameter will allow to limit setting a use can do (which could be confusing). Signed-off-by: Frediano Ziglio <fziglio@redhat.com> Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
2015-07-15hw/arm/boot: Increase fdt alignmentAlexander Graf
The Linux kernel on aarch64 creates a page table entry at early bootup that spans the 2MB range on memory spanning the fdt start address: [ ALIGN_DOWN(fdt, 2MB) ... ALIGN_DOWN(fdt, 2MB) + 2MB ] This means that when our current 4k alignment happens to fall at the end of the aligned region, Linux tries to access memory that is not mapped. The easy fix is to instead increase the alignment to 2MB, making Linux's logic always succeed. We leave the existing 4k alignment for 32bit kernels to not cause any regressions due to space constraints.

2015-07-14watchdog/diag288: correctly register for system reset requestsXu Wang
The diag288 watchdog is no sysbus device, therefore it doesn't get triggered on resets automatically using dc->reset. Let's register the reset handler manually, so we get correctly notified again when a system reset was requested. Also reset the watchdog on subsystem resets that don't trigger a full system reset.
