2012-03-27xen_console: ignore console disconnect events from console/0Stefano Stabellini1-0/+3
The first console has a different location compared to other PV devices (console, rather than device/console/0) and doesn't obey the xenstore state protocol. We already special case the first console in con_init and con_initialise, we should also do it in con_disconnect. Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>
2011-09-09Introduce a new 'connected' xendev op called when Connected.John Haxby1-2/+2
Rename the existing xendev 'connect' op to 'initialised' and introduce a new 'connected' op. This new op, if defined, is called when the backend is connected. Note that since there is no state transition this may be called more than once. Signed-off-by: John Haxby <john.haxby@oracle.com> Signed-off-by: Stefano Stabellini <stefano.stabellini@eu.citrix.com>

2011-07-17xen_console: fall back to qemu serial deviceAlexander Graf1-4/+7
The new xen_console protocol changed the default xen_console output device from whatever Qemu chose to whatever xenstore choses and "pty" as fallback. This is not how Qemu works. It has its own serial redirection semantics. So it xenstore doesn't contain information on what to do, Qemu is the place to ask. Signed-off-by: Alexander Graf <agraf@suse.de>
2011-07-17xen_console: support the new extended xenstore protocolStefano Stabellini1-6/+10
Since CS 21994 on xen-unstable.hg and CS 466608f3a32e1f9808acdf832a5843af37e5fcec on qemu-xen-unstable.git, few changes have been introduced to the PV console xenstore protocol, as described by the document docs/misc/console.txt under xen-unstable.hg. From the Qemu point of view, very few modifications are needed to correctly support the protocol: read from xenstore the "output" node that tell us what the output of the PV console is going to be. In case the output is a tty, write to xenstore the device name. Changes in v2: - fix error paths: free malloc'ed strings and close the xenstore connection before returning; - remove useless snprintf in xenstore_store_pv_console_info if i == 0. Changes in v3: - replace xs_daemon_open/xs_daemon_close with xs_open/xs_close. Changes in v4: - add a compatibility implementation of xs_open/xs_close. Changes in v5: - fix code style.
