2013-02-01sparc: disable qtest in make checkAnthony Liguori1-2/+2
We've seen this repeatedly in buildbot but I can now reliably reproduce it myself too. With a few hundred runs of 'make check', qemu-system-sparc will hang consuming 100% CPU. I've attached GDB to the hung process and unfortunately, I can't get anything useful out of GDB (RIP is not a valid simple and there is nothing else on the stack). At any rate, since this only manifests in qemu-system-sparc and it doesn't appear to be a qtest specific problem, I think we should disable it until the problem is resolved.

2013-02-01virtio-net: migration support for multiqueueJason Wang1-6/+29
This patch add migration support for multiqueue virtio-net. Instead of bumping the version, we conditionally send the info of multiqueue only when the device support more than one queue to maintain the backward compatibility.

2013-02-01virtio-net: multiqueue supportJason Wang2-67/+263
This patch implements both userspace and vhost support for multiple queue virtio-net (VIRTIO_NET_F_MQ). This is done by introducing an array of VirtIONetQueue to VirtIONet. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-02-01virtio-net: separate virtqueue from VirtIONetJason Wang1-81/+114
To support multiqueue virtio-net, the first step is to separate the virtqueue related fields from VirtIONet to a new structure VirtIONetQueue.

2013-02-01vhost: multiqueue supportJason Wang5-58/+120
This patch lets vhost support multiqueue. The idea is simple, just launching multiple threads of vhost and let each of vhost thread processing a subset of the virtqueues of the device. After this change each emulated device can have multiple vhost threads as its backend. To do this, a virtqueue index were introduced to record to first virtqueue that will be handled by this vhost_net device. Based on this and nvqs, vhost could calculate its relative index to setup vhost_net device. Since we may have many vhost/net devices for a virtio-net device. The setting of guest notifiers were moved out of the starting/stopping of a specific vhost thread. The vhost_net_{start|stop}() were renamed to vhost_net_{start|stop}_one(), and a new vhost_net_{start|stop}() were introduced to configure the guest notifiers and start/stop all vhost/vhost_net devices.

2013-02-01tap: multiqueue supportJason Wang9-44/+139
Recently, linux support multiqueue tap which could let userspace call TUNSETIFF for a signle device many times to create multiple file descriptors as independent queues. User could also enable/disabe a specific queue through TUNSETQUEUE. The patch adds the generic infrastructure to create multiqueue taps. To achieve this a new parameter "queues" were introduced to specify how many queues were expected to be created for tap by qemu itself. Alternatively, management could also pass multiple pre-created tap file descriptors separated with ':' through a new parameter fds like -netdev tap,id=hn0,fds="X:Y:..:Z". Multiple vhost file descriptors could also be passed in this way. Each TAPState were still associated to a tap fd, which mean multiple TAPStates were created when user needs multiqueue taps. Since each TAPState contains one NetClientState, with the multiqueue nic support, an N peers of NetClientState were built up. A new parameter, mq_required were introduce in tap_open() to create multiqueue tap fds. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-02-01tap: introduce a helper to get the name of an interfaceJason Wang7-0/+33
This patch introduces a helper tap_get_ifname() to get the device name of tap device. This is needed when ifname is unspecified in the command line and qemu were asked to create tap device by itself. In this situation, the name were allocated by kernel, so if multiqueue is asked, we need to fetch its name after creating the first queue. Only linux has this support since it's the only platform that supports multiqueue tap. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-02-01tap: support enabling or disabling a queueJason Wang3-3/+52
This patch introduce a new bit - enabled in TAPState which tracks whether a specific queue/fd is enabled. The tap/fd is enabled during initialization and could be enabled/disabled by tap_enalbe() and tap_disable() which calls platform specific helpers to do the real work. Polling of a tap fd can only done when the tap was enabled. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-02-01tap: add Linux multiqueue supportJason Wang6-0/+97
This patch add basic multiqueue support for Linux. When multiqueue is needed, we will first check whether kernel support multiqueue tap before creating more queues. Two new functions tap_fd_enable() and tap_fd_disable() were introduced to enable and disable a specific queue. Since the multiqueue is only supported in Linux, return error on other platforms.

2013-02-01tap: factor out common tap initializationJason Wang1-57/+73

2013-02-01tap: import linux multiqueue constantsJason Wang1-0/+4
Import multiqueue constants from if_tun.h from 3.8-rc3. A new ifr flag IFF_MULTI_QUEUE were introduced to create a multiqueue backend by calling TUNSETIFF with the this flag and with the same interface name many times. A new ioctl TUNSETQUEUE were introduced. When doing this ioctl with IFF_DETACH_QUEUE, the queue were disabled in the linux kernel. When doing this ioctl with IFF_ATTACH_QUEUE, the queue were enabled in the linux kernel. Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: Anthony Liguori <aliguori@us.ibm.com>
2013-02-01net: multiqueue supportJason Wang6-48/+139
This patch adds basic multiqueue support for qemu. The idea is simple, an array of NetClientStates were introduced in NICState, parse_netdev() were extended to find and match all NetClientStates belongs to the backend and place their pointers in NICConf. Then qemu_new_nic can setup a N:N mapping between NICStates that belongs to a nic and NICStates belongs to the netdev. And a queue_index were introduced in NetClientState to track its index. After this, each peers of a NICState were abstracted as a queue. After this change, all NetClientState that belongs to the same backend/nic has the same id. When use want to change the link status, all NetClientStates that belongs to the same backend/nic will be also changed. When user want to delete a device or netdev, all NetClientStates that belongs to the same backend/nic will be deleted also. Changing or deleting an specific queue is not allowed.

2013-02-01net: introduce NetClientState destructorJason Wang2-4/+15

2013-02-01net: introduce qemu_net_client_setup()Jason Wang1-10/+19

2013-02-01net: introduce qemu_find_net_clients_except()Jason Wang2-0/+23
In multiqueue, all NetClientState that belongs to the same netdev or nic has the same id. So this patches introduces an helper qemu_find_net_clients_except() which finds all NetClientState with the same id. This will be used by multiqueue networking.

2013-02-01net: intorduce qemu_del_nic()Jason Wang10-9/+23
To support multiqueue nic, this patch separate the nic destructor from qemu_del_net_client() to a new helper qemu_del_nic() since the mapping bettween NiCState and NetClientState were not 1:1 in multiqueue.

2013-02-01libqtest: Wait for the right child PID after killing QEMUEduardo Habkost1-2/+5
When running "make check" with gcov enabled, we get the following message: hw/tmp105.gcda:cannot open data file, assuming not executed The problem happens because: * tmp105-test exits before QEMU exits, because waitpid() at qtest_quit() fails; * waitpid() fails because there's another process already waiting for the QEMU process; * The process that is already waiting for QEMU is the child created by qtest_init() to run system(); * qtest_quit() is incorrectly waiting for the QEMU PID directly instead of the child created by qtest_init(). This fixes the problem by sending SIGTERM to QEMU, but waiting for the child process created by qtest_init() (that exits immediately after QEMU exits).

2013-02-01configure: Keep -Werror enabled for Release CandidatesAndreas Färber1-1/+1
The automatic drop of -Werror during the RC phases has in the past led to warnings creeping into submaintainer trees. Last QEMU Summit it was concluded that -Werror should stay on and enabled only as part of the release process. To relieve our release manager, instead of always enabling -Werror or doing some number magic, let's enable it depending on whether a .git/ directory exists in the source tree.

2013-02-01Revert "e1000: no need auto-negotiation if link was down"Michael Roth1-5/+0
This reverts commit 84dd2120247a7d25ff1bb337de21c0e76816ad2d. I'm not sure what issue the original commit was meant to fix, or if the logic is actually wrong, but it causes e1000 to stop working after a guest issues a reset. >From what I can tell a guest with an e1000 nic has no way of changing the link status, as far as it's NetClient peer is concerned, except in the auto-negotiation path, so with this patch in place there's no recovery after a reset, since the link goes down and stays that way. Revert this patch now to fix the bigger problem, and handle any lingering issues with a follow-up. Reproduced/tested with qemu-jeos and Ubuntu 12.10.
