Hello, For the VirtioSerial F13 feature, a few patches need to be backported from the linux-next tree. Rusty has put them up in his local queue and they'll be pushed to Linus for 2.6.34. The patches are 42de322 virtio: console: statically initialize virtio_cons ddb20f0 hvc_console: make the ops pointer const. 14f5b2b virtio: console: We support only one device at a time 502d56a virtio: console: port encapsulation bd035b3 virtio: console: encapsulate buffer information in a struct db5f217 virtio: console: ensure add_inbuf can work for multiple ports as well 8bd5af9 virtio: console: introduce a get_inbuf helper to fetch bufs from in_vq 44ee715 virtio: console: use vdev->priv to avoid accessing global var. 982892b virtio: console: don't assume a single console port. fadef8b virtio: console: remove global var 1d6770b virtio: console: struct ports for multiple ports per device. 468f638 virtio: console: ensure console size is updated on hvc open 9f6d918 virtio: console: Separate out console-specific data into a separate struct 07efa05 virtio: console: Separate out console init into a new function 6191b29 virtio: console: Separate out find_vqs operation into a different function bfd9f44 virtio: console: Introduce function to hand off data from host to readers e5b54b53 virtio: console: Introduce a send_buf function for a common path for sending data to host 8d5e5a7 virtio: console: Add a new MULTIPORT feature, support for generic ports 5966ef0 virtio: console: Prepare for writing to / reading from userspace buffers 2e62003 virtio: console: Associate each port with a char device 4954379 virtio: console: Add file operations to ports for open/read/write/poll 606ac80 virtio: console: Ensure only one process can have a port open at a time c888962 virtio: console: Register with sysfs and create a 'name' attribute for ports 42eefd8 virtio: console: Remove cached data on port close 7c0ba1b virtio: console: Handle port hot-plug 9fe551d virtio: Add ability to detach unused buffers from vrings d201dd5 virtio: console: Add ability to hot-unplug ports 0f015e0 virtio: console: Add debugfs files for each port to expose debug info b431126 virtio: console: show error message if hvc_alloc fails for console ports from today's linux-next tree. The changes are confined to the drivers/virtio_console.c file (and a few other drivers/char/hvc* files) which haven't seen changes since 2.6.32, so these patches should apply as-is to the feodra tree. A patch that was merged in the 2.6.33 cycle also is needed: c0cefeb hvc_console: Export (GPL'ed) hvc_remove I can send these patches out as a patch series if that's easier for review.
