* hw/core/machine: Display CPU model name in 'info cpus' commandPhilippe Mathieu-Daudé2025-07-151-1/+3

* qapi: Move include/qapi/qmp/ to include/qobject/Daniel P. Berrangé2025-02-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | The general expectation is that header files should follow the same file/path naming scheme as the corresponding source file. There are various historical exceptions to this practice in QEMU, with one of the most notable being the include/qapi/qmp/ directory. Most of the headers there correspond to source files in qobject/. This patch corrects most of that inconsistency by creating include/qobject/ and moving the headers for qobject/ there. This also fixes MAINTAINERS for include/qapi/qmp/dispatch.h: scripts/get_maintainer.pl now reports "QAPI" instead of "No maintainers found". Signed-off-by: Daniel P.

* qapi machine: Elide redundant has_FOO in generated CMarkus Armbruster2022-12-141-1/+1
| | | | | | | | | | | | | | | | | The has_FOO for pointer-valued FOO are redundant, except for arrays. They are also a nuisance to work with. Recent commit "qapi: Start to elide redundant has_FOO in generated C" provided the means to elide them step by step. This is the step for qapi/machine*.json. Said commit explains the transformation in more detail. The invariant violations mentioned there do not occur here.

* qapi: introduce x-query-numa QMP commandDaniel P. Berrangé2021-11-021-35/+0
| | | | | | | | | | | This is a counterpart to the HMP "info numa" command. It is being added with an "x-" prefix because this QMP command is intended as an adhoc debugging tool and will thus not be modelled in QAPI as fully structured data, nor will it have long term guaranteed stability. The existing HMP command is rewritten to call the QMP command. Reviewed-by: Philippe Mathieu-Daudé <philmd@redhat.com> Signed-off-by: Daniel P. Berrangé <berrange@redhat.com>
