[Qemu-devel] [PATCH v2 0/9] qom: HMP commands to supersede info qtree |
Date: |

Hello,
The main patch of this series is an HMP command "info qom-tree",
which displays the machine composition tree. This names all objects,
including those missing in "info qtree" for lack of bus or for not being a
device.
Properties can be listed with "qom-list" and set with "qom-set", like in QMP.
"qom-get" and displaying properties as part of "info qom-tree" ran into
StringOutputVisitor limitations - this v2 therefore stubs that support out
so that we don't crash.
This series has been around for a year now; I hope to get at least qom-list and
the basic info qom-tree into v2.3, as visualization of my upcoming CPU changes.
Also included are two proposed cleanups of nodes in /machine namespace.
By making it easier to inspect the tree, I hope we'll detect this earlier.
Regards,
Andreas
v1 -> v2:
* Included qom-tree script in series, updating Anthony's email address (Eric)
and dropping reference to "info qtree" from subject (Paolo);
script did otherwise not change, so leaving 2013 copyright
* Renamed from "info qom-composition" to "info qom-tree" (Hani/Paolo)
* Renamed functions from do_* to hmp_* according to changed surrounding code
* Simplified qom-list according to Hani's suggestion
* Added warning for ambiguous paths to qom-set (Hani)
* Added patch stubbing out StringOutputVisitor struct support for qom-get (Hani)
* Added documentation for info qom-tree
* Implemented "info qom-tree /foo" and "info qom-tree -v" options
* Added patch cleaning up MemoryRegion nodes from /machine
* Added patch cleaning up IRQ nodes from /machine
