Hi all, This patch series proposes the specification of a new virtio device on which we are working on, namely the Signal Distribution Module (SDM). The SDM routes inter-processor signals intra and inter QEMU instances, using a user-defined communication channel. At the current state the SDM provides a local channel, for intra-QEMU signals, and a channel based on sockets (UNIX or TCP) to exchange signals between processors in different instances of QEMU. Each communication channel exports a common interface for the sake of ease of extension and integration of new channels.
In addition to the virtio version, a platform device version is available as well to be used for cases where a processor is not running Linux but another OS/firmware that does not support virtio. This patch is related to : [Qemu-devel][RFC v3 0/6] SDM Interface where you can find the latest RFC patch set for the QEMU code of the virtio SDM device. Kernel code is publicly accessible from: https://git.virtualopensystems.com/dev/qemu-het-tools branch sdm_test_virtio_mod_v2. QEMU code is accessible from: https://git.virtualopensystems.com/dev/qemu-het-tools branch sdm-dev-v3 Thanks, Christian Christian Pinto (2): content: reserve virtio device ID virtio-sdm: new device specification content.tex | 4 ++ virtio-sdm.tex | 126 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++ 2 files changed, 130 insertions(+) create mode 100644 virtio-sdm.tex -- 1.9.1
