2013-02-21aio: convert aio_poll() to g_poll(3)Stefan Hajnoczi1-0/+3
AioHandler already has a GPollFD so we can directly use its events/revents. Add the int pollfds_idx field to AioContext so we can map g_poll(3) results back to AioHandlers. Reuse aio_dispatch() to invoke handlers after g_poll(3).

Replace some x86_64 specific inline assembly with something that all 64-bit hosts ought to optimize well. At worst this becomes a call to the gcc __multi3 routine, which is no worse than our implementation in util/host-utils.c. With gcc 4.7, we get identical code generation for x86_64. We now get native multiplication on ia64 and s390x hosts. With minor improvements to gcc we can get it for ppc64 as well.

2013-02-04cutils: unsigned int parsing functionsEduardo Habkost1-0/+4
There are lots of duplicate parsing code using strto*() in QEMU, and most of that code is broken in one way or another. Even the visitors code have duplicate integer parsing code[1]. This introduces functions to help parsing unsigned int values: parse_uint() and parse_uint_full(). Parsing functions for signed ints and floats will be submitted later. parse_uint_full() has all the checks made by opts_type_uint64() at opts-visitor.c: - Check for NULL (returns -EINVAL) - Check for negative numbers (returns -EINVAL) - Check for empty string (returns -EINVAL) - Check for overflow or other errno values set by strtoll() (returns -errno) - Check for end of string (reject invalid characters after number) (returns -EINVAL) parse_uint() does everything above except checking for the end of the string, so callers can continue parsing the remainder of string after the number. Unit tests included. [1] string-input-visitor.c:parse_int() could use the same parsing code used by opts-visitor.c:opts_type_int(), instead of duplicating that logic.

2013-02-01tap: multiqueue supportJason Wang1-1/+0
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 Wang1-0/+1
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 Wang1-0/+2
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>
2013-02-01net: multiqueue supportJason Wang1-4/+14
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.

This broke as part of build system refactorings while CPU patches were in flight, adding conditional fields kvm_fd (8737c51c0444f832c4e97d7eb7540eae457e08e4) and kvm_vcpu_dirty (20d695a9254c1b086a456d3b79a3c311236643ba) for softmmu. linux-user and bsd-user would therefore get a CPUState type with instance_size ~8 bytes longer than expected. Fix this by unconditionally having the fields in CPUState. In practice, target-specific CPU types' instance_size would compensate this, and upstream qom/cpu.c does not yet touch any affected field.
