Hey Rusty, This patchset is on top of the previous one. It sends a SIGIO signal to apps that request signals for host activity. SIGIO is sent on host connect, disconnect as well as hot-unplug (which can be seen as a special case of host disconnect). Tested using several testcases in the test-virtserial repo: http://fedorapeople.org/gitweb?p=amitshah/public_git/test-virtserial.git Please apply.

Hi Rusty, The main thing in these patches is the introduction of injecting SIGIO on host-side connect/disconnect events and when new data is available for ports. The first two patches fix bugs that I haven't seen, but look like the right thing to do. These have been tested extensively using the test-virtserial test suite. Please apply, Amit. Amit Shah (4): virtio: console: Un-block

From: Hans de Goede <hdegoede at redhat.com> I found this while working on a Linux agent for spice, the symptom I was seeing was select blocking on the spice vdagent virtio serial port even though there were messages queued up there. virtio_console's port_fops_poll checks port->inbuf != NULL to determine if read won't block. However if an application reads enough bytes from

Hi All, The following patch set provides a low-overhead system for collecting kernel tracing data of guests by a host in a virtualization environment. A guest OS generally shares some devices with other guests or a host, so reasons of any problems occurring in a guest may be from other guests or a host. Then, to collect some tracing data of a number of guests and a host is needed when some
