Hello,
I am trying to find if there is a way to inject a given binary into guest
code. If there isn't a way to do it, I would like to write a module which
would let us do it. Can somebody suggest what would be nice to have in such
a module?
Thanks,
Aravind.
Instead of writing very compact code, declare all registers that are
clobbered or reserved one by one. This makes the code easier to read.
Also declare all the 16 registers to TCG, and mark pc as reserved.

First, we do some QError usage cleanup in handle_qmp_command() and then
really fix the bug in the last patch.
The QERR_QMP_BAD_INPUT_OBJECT error is going to be used only
for two problems: the input is not an object or the "execute"

Hello,
This patchset introduces flow control to virtio-console and
chardev-based virtio serial ports. This series is based on the
previous series I sent on Mar 31st (00/17: v4: virtio-serial fixes,
new abi for port discovery)
The qemu chardevs can now return -EAGAIN when a non-blocking remote
isn
We were assuming that once unthrottled, ports could accept any amount of
data without getting throttled again.
Fix this assumption.

Disable throttling once a port is closed (and we discard all the
unconsumed buffers in the vq).

The guest kernel can reclaim the buffers when it receives the port close
event or when a port is being removed. Ensure we free up the buffers
before we send out any events to the guest.

Show whether a port is throttled in 'info qtree'.
Also reduce LOC by 1 by assigning 'throttled' status just once.

On writing errors, we just returned -1 even if some bytes were already
written out. Ensure we return the number of bytes written before we
return the error (on a subsequent call to qemu_chr_write()).

If the chardev we're writing to is nonblocking, just report -EAGAIN to
the caller so that the caller can take any further action if it so
wishes.

The initialisation for generic ports and console ports is similar.
Factor out the parts that are the same in a different function that can
be called from each of the initfns.

If the char device we're connected to is overwhelmed with data and it
can't accept any more, signal to the virtio-serial-bus to stop sending
us more data till we tell otherwise.
If the current buffer being processed hasn't been completely written out
to the char device, we have to keep it around a
I am still not able to figure out, how to use it.
Can you please point me to some document or give little bit more details,
how shall I use sshfs?
I am using *qemu -kernel kernelimage -initrd initrd.img /dev/zero -append

Changes from v3->v4:
* Use the standard implementation of load-locked/store-conditional.
I think it's pretty gross, but probably better to be consistent
with the other ports. And at least the port continues to build
when the host compiler doesn't support __sync_bool_compare_and_swap.
It's a simple mask and shift sequence.
Also, fix a typo in the actual masks used.

The inverted conditions as argument to the function looks wrong
at a glance inside translate_one. Since we have an easy function
to produce the inversion now, use it.

This is a per-cpu flag; there's no need for a spinlock of any kind.
We were also failing to manipulate the flag with $31 as a target reg
and failing to clear the flag on execution of a return-from-interrupt
instruction.

A minimal implementation that more or less corresponds to the

to be jumped through when alpha gets system-level emulation.
