The problem is that the Linux driver expects the master transaction inhibit
bit(R_SPICR_MTI) to be set during driver initialization so that it can
detect the fifo size but QEMU defaults it to zero out of reset. The

Firm "no". The PL011 is a perfectly good UART widely
supported by guest OSes, and there is no reason
why we should want to a

As the Xen backend operations were abstracted out into a function table to
allow for internally emulated Xen support, we missed the xen_init_pv()
code path which also needs to install the operations for the true Xen
libraries. Add the missing call to setup_xen_backend_ops().

query-vcpu-dirty-limit's doc comment has an example, but it shows only
input, no output:
##

# Returns information about virtual CPU dirty page rate limits, if any.

Hi,
There is a feature I prepared which may be practical for some QEMU users.
The feature provides a new I2C slave device
that prepares a message depending what i2c-slave callback was called
and sends it outside of QEMU through the character device to a client
that receives that message, processe

When dm_restrict is set, QEMU isn't permitted to update the XenStore node
to indicate its running status. Previously, the xs_write() call would fail
but the failure was ignored.
However, in refactoring to allow for emulated XenStore operations, a new
call to xs_open() was a
