[PATCH] xen: Enable Xen console by default in domU
Without console= arguments on the kernel command line, the first
console to register becomes enabled and the preferred console (the one
behind /dev/console). This is tty (assuming CONFIG_VT_CONSOLE is
enabled, which it commonly is).
This is okay as long tty is a useful console. But unless we have the
PV framebuffer, and it is enabled for this domain, tty0 in domU is
merely a dummy. In that

[PATCH 0/5] xen pvfb: Para-virtual framebuffer, keyboard and pointer driver updates
This is an update to the Linux part of the Xen PVFB. Linux Xen PVFB
is a pair of Xen para-virtual frontend device drivers:
drivers/video/xen-fbfront.c provides a framebuffer, and
drivers/input/xen-kbdfront provides keyboard and mouse. Their
backends run in dom0 user space.
Parts in this patch series:
1. Enable Xen console by default in domU
2. Pointer z-axis (mouse wheel) support
3. Module

[PATCH] xen/hvc: Fix polling mode to work with kdb/kgdb
Fix the polling section of the hvc driver to use the global "last_hvc"
variable, rather than the ttys.
With this change debugging a xen dom0 kernel is possible via the
following kernel parameter:
kgdboc=hvc0

[RFC 0/3]: hvc_console rework for platform without hard irqs
This patch set if my first attempt to make virtio_console usable on s390.
To do so, I had to change hvc_console, because s390 has no request_irq and
no free_irq.
I want to get feedback from the main users of hvc_console before I proceed.
The basic idea of this patch set is to remove the calls to request_irq and
free_irq and replace them with backend specific callbacks.
Please see the

You shouldn't use 'static' data either, that's not always guaranteed to
be DMA-able, right?

[PATCH 00/31] virtio: console: Fixes, multiple devices and generic ports
Hey Rusty,
This series adds support for generic ports with each port getting two
vqs: one for input and one for output. The host notifies us via the
config space of the max. number of ports that can be added for a
particular device.
As a result of that change, the buffer management for find_readbufs
and send_bufs is moved to the vqs. Only one outbuf per port is used
so we bide away some time in

[PATCH 00/32] virtio: console: Fixes, multiple devices and generic ports
Hey Rusty,
In this version:
- Assume only one inbuf; no input buffering for ports
- Remove the START/END delimiters for outgoing buffers
- Remove the header that was sent along with each buffer
- Remove unused buffers in the vqs at port remove time
- Send a guest port open message to the host when a console port is
attached
- Remove cached buffers when ports are closed / disconnected
- Send
