Hi!
I think this series still make sense, even though the dirty ring patch
haven't been merged.
Using the -accel to specify accelerator is more graceful and more
feature such as kernel-irqchip锛宬vm-shadow-mem锛宼b-size锛宔tc, can be
specified via domain xml if we continue doing this work, rather than
hard-writing code or using QEMU command line.
Thanks!

This patchset aims to support dirty ring feature which has been introduced
in kernel:
https://lore.kernel.org/lkml/8b3f68dd-c61c-16a0-2077-0a5d3d57a357@xxxxxxxxxx/
The QEMU patchset is also being applied for merge, the review may be under
the way:
https://lore.kernel.org/qemu-devel/20210108164601.406146-1-peterx@xxxxxxxxxx/
Since QEMU enable the dirty ring feature by specifying the "-accel" sub-parameter.
Libvirt use "-machine accel=xxx" option to specify the type of accelerator by
default, which is conflict with QEMU. Either the Libvirt or QEMU may compromise,
According to the Paolo Bonzini's patient and prompt explanation:
https://lore.kernel.org/qemu-devel/3aa73987-40e8-3619-0723-9f17f73850bd@xxxxxxxxxx/
We'd like to have Libvirt switch to "-accel xxx" instead, cause the "-machine"
options for accelerator are legacy and now there is a better mechanism.
This two patches are kind of standalone so maybe it cound be merged in advance
anyway. And the dirty-ring-support patch is reviewed under the way. Once the QEMU
patchset is merged, i'll ping the libvir-list and apply for merge the remainding
patch. The following are details:
https://www.redhat.com/archives/libvir-list/2021-January/msg00660.html
The 2 patches do the following things:
1. introduce QEMU_CAPS_ACCEL so the the next patch can use it to choose the right
option when specifying the accelerator type.
2. switch the option "-machine accel=xxx" to "-accel xxx" when specifying accelerator
type once libvirt build QEMU command line, so that the next patch can build
QEMU command line for accelerator type using "-accel xxx" directly.
Please review, Thanks!
Best Regards !

qemu: use "-accel" option to specify accelerator instead of "-machine"
