The recent fix didn't actually fix the whole problem. Operations can't
only wait for themselves, but we can also end up with circular
dependencies like two operations waiting for each other to complete.
This reverts the first fix and implements another approach.
Kevin Wolf (2):
Revert "mirror:
This reverts commit 7e6c4ff792734e196c8ca82564c56b5e7c6288ca.
The fix was incomplete as it only protected against requests waiting for
themselves, but not against requests waiting for each other. We need a
different solution.

They change the hardware and CPU features that is presented to the VMs,
if the respective

Public bug reported:
I want to use qemu-arm-static to cross-compile software. The compiler
itself is a native cross-compiler connected via "distcc".
The problem is that a script tries to do some stuff with "git" and with
a "git clone -s" command the whole story reproducibly stops with a
Thank you for the explanation. I actually built it for "Virt" machine.
I'll try the "sifive_u" when I can.
But I guess your explanation is correct so this bug could be closed from

According to [1], this is still an issue today.

Currently, attempting to unplug an NVLink2 device will generally
result in the guest crashing. If you're lucky, it instead simply
won't work and remain in a "pending unplug" state indefinitely.
There is code we could we could theoretically improve in qemu to tear
these devices down better.
Currently spapr_phb_nvgpu_populate_pcidev_dt() works a little cryptically.
It steps through all the NVLink2 GPUs and NPUs and if they match the device
we're called for, we generate the relevant device tree information.
Make this a little more obvious by introducing helpers to determine it a

This will allow to reuse a single generic .bdrv_co_create
implementation for several drivers.
No functional changes.

The recent patches from Max Reitz allowed some block drivers to not
provide the .bdrv_co_create_opts and still allow qemu-img to
create/format images as long as the image is already existing
(that is the case with various block storage drivers like nbd/iscsi/nvme, etc)
