If you only want to use the package that is provided with your Linux
distribution, you should report bugs to the distribution bug tracker
instead, i.e. set Target -> Distribution = Ubuntu, Package = QEMU.
Please don't use Project = qemu in that case. Thanks!

Hello, folks.
There is some optimization activity in MIPS target, and we have some simple
micro-benchmarks for measuring speed of emulation of a single target

Hi,
This series refactor the superio code used in the mips_r4k machine, adding the
TYPE_R4K_SUPERIO device.
Doing so we improve the ISASuperIODevice, fixing an easy bug.
This series also demonstrate that no machine access a I8042 ISA device out of a
Super I/O chipset.
Regards,
Phil.
ISA Super I/O are already modeled by the ISASuperIODevice abstract
device.
Since this board uses a generic ISA Super I/O chipset, refactor it
as the TYPE_R4K_SUPERIO device, child of ISASuperIODevice.

Refactor s390_get_ccw_device() to return device type. This prevents us from
having to use messy casting logic in several places.

Create a boot_setup function to handle getting boot information from
the machine/hypervisor. This decouples common boot logic from the
virtio code path and allows us to make use of it for the real dasd boot
scenario.

Create a new header for basic architecture specific definitions and add a
mapping of low core memory. This mapping will be used by the real dasd boot
process.

We need a method for finding the subchannel of a dasd device. Let's
modify find_dev to handle this since it mostly does what we need. Up to
this point find_dev has been specific to only virtio devices.

Move channel i/o setup code out to a separate function. This decouples cio

This is to support booting from vfio-ccw dasd devices. We basically implement
the real hardware ipl procedure. This allows for booting Linux guests on
vfio-ccw devices.
vfio-ccw's channel program prefetch algorithm complicates ipl because most ipl
channel programs dynamically modify themselves.

This is just a compat symlink for a very old history.
It should not be used directly anymore, but then also not matter.
