[Qemu-devel] [PATCH 0/7 v9] vhost-user multiple queue support

Hi, Here is the updated patch set for enabling vhost-user multiple queue. This patch set introduces 2 more vhost user messages: VHOST_USER_GET_QUEUE_NUM, for querying how many queues the backend supports, and VHOST_USER_SET_VRING_ENABLE, for enabling/disabling a specific virt queue. Both of the

[Qemu-devel] [PATCH 4/7] vhost-user: add VHOST_USER_GET_QUEUE_NUM message

This is for querying how many queues the backend supports if it has mq support(when VHOST_USER_PROTOCOL_F_MQ flag is set from the quried protocol features). vhost_net_get_max_queues() is the interface to export that value, and to tell if the backend supports # of queues user requested, which is do

[Qemu-devel] [PULL 6/6] gtk: use setlocale() for LC_MESSAGES only

From: Alberto Garcia The QEMU code is not internationalized and assumes that it runs under the C locale, but if we use the GTK+ UI we'll end up importing the locale settings from the environment. This can break things, such as the JSON generator and iotest 120 in locales that use a decimal comma.

Kick off all grabbing logic from fullscreen mode. In the current state it seems to create more problems than it solves. Try running qemu/gtk fullscreen on one head of a multihead host for example ... There probably was a reason the grab-on-fullscreen logic was added in the first place. So pleas
