2014-09-03vhost_net: start/stop guest notifiers properlyJason Wang1-14/+27
commit a9f98bb5ebe6fb1869321dcc58e72041ae626ad8 "vhost: multiqueue support" changed the order of stopping the device. Previously vhost_dev_stop would disable backend and only afterwards, unset guest notifiers. We now unset guest notifiers while vhost is still active. This can lose interrupts causing guest networking to fail. In particular, this has been observed during migration. To fix this, several other changes are needed: - remove the hdev->started assertion in vhost.c since we may want to start the guest notifiers before vhost starts and stop the guest notifiers after vhost is stopped. - introduce the vhost_net_set_vq_index() and call it before setting guest notifiers. This is to guarantee vhost_net has the correct virtqueue index when setting guest notifiers. MST: fix up error handling.

2014-08-14e1000: correctly handle phy_ctrl reserved & self-clearing bitsGabriel L. Somlo1-14/+17
Make phyreg_writeops responsible for actually writing their respective phy registers, rather than rely on set_mdic() to do it on their behalf. The only current instance of phyreg_writeops is set_phy_ctrl(); modify it to write the register on its own, while also correctly handling reserved and self-clearing bits. have_autoneg() does not need to check for MII_CR_RESTART_AUTO_NEG, since the only time the flag comes into play is during set_phy_ctrl(), and, following this patch, never actually gets written to the phy control register.

2014-06-29vhost-net: disable when cross-endianGreg Kurz1-0/+19
As of today, vhost assumes guest and host have the same endianness. This is definitely not compatible with modern PPC64 and ARM that can change endianness at runtime. Let's disable vhost-net and print an error message when we detect such a case: qemu-system-ppc64: vhost-net does not support cross-endian qemu-system-ppc64: unable to start vhost net: 38: falling back on userspace virtio This way users can continue to run VMs without changing their setup and have a chance to know that performance will be impacted.

In order to migrate virtio subsections, they should be streamed after the device itself. We need the device specific code to be called from the common migration code to achieve this.

2014-06-29virtio-net: byteswap virtio-net headerCédric Le Goater1-0/+17
TCP connectivity fails when the guest has a different endianness. The packets are silently dropped on the host by the tap backend when they are read from user space because the endianness of the virtio-net header is in the wrong order. These lines may appear in the guest console: [ 454.709327] skbuff: bad partial csum: csum=8704/4096 len=74 [ 455.702554] skbuff: bad partial csum: csum=8704/4096 len=74 The issue that got first spotted with a ppc64le PowerKVM guest, but it also exists for the less common case of a x86_64 guest run by a big-endian ppc64 TCG hypervisor.

2014-06-27hw/net/eepro100: Implement read-only bits in MDI registersPeter Maydell1-2/+2
Although we defined an eepro100_mdi_mask[] array indicating which bits in the registers are read-only, we weren't actually doing anything with it. Make the MDI register-write code use it rather than manually making register 1 read-only and leaving the rest as reads-as-written. (The special-case handling of register 0 remains as before since its mask is all-zeros and the special casing happens before we apply the masking.)

2014-06-23e1000: improve auto-negotiation reporting via mii-toolGabriel L. Somlo2-1/+7
Using mii-tool (on F20-live), the following output is produced: SIOCGMIIREG on ens3 failed: Input/output error ens3: no autonegotiation, 1000baseT-FD flow-control, link ok The first line (SIOCGMIIREG error) is due to mii-tool's inability to read the PHY auto-negotiation expansion register. On the second line, "no autonegotiation" is wrong, and caused by the absence of a flag in the link partner ability register which would indicate that our link partner has acked us. This flag is listed as "reserved" in the Intel e1000 manual, but mii-tool uses it as LPA_LPACK from /usr/include/linux/mii.h. This patch adds read access to PHY_AUTONEG_EXP and defines the link partner ack flag, allowing mii-tool to generate output as normally expected: ens3: negotiated 1000baseT-FD flow-control, link ok Signed-off-by: Gabriel Somlo <somlo@cmu.edu> Reviewed-by: Alexander Graf <agraf@suse.de> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Reviewed-by: Michael S.

AUTONEG_COMPLETE during link_down() - set PHY status reg. AUTONEG_COMPLETE during autoneg_timer() only if we actually brought the link up. - group all checks for "can we, and should we autonegotiate?" together for more clarity.
